When the first group of controllable display areas 13 is lit, the following pattern is obtained:

referring to fig. 4, a first pattern group 14 (corresponding to a first controllable display area group 13) is displayed on the first display image, the first pattern group 14 includes a plurality of elliptical ring-shaped first patterns 110 (one first controllable display area 100 corresponds to one first pattern 110), the lengths of the major axes of the first patterns 110 in the first pattern group 14 are different from each other, the major axes of the first patterns 110 in the first pattern group 14 are approximately parallel, the eccentricity is approximately equal, and the minor axes are approximately on the same straight line, the plurality of first patterns 110 are arranged according to the size, the small-sized first patterns 110 are located in the large-sized first patterns 110, the first pattern 110 with the largest size is a first pattern 111, each of the first patterns 110 has a first minor axis point and a second minor axis point (refer to the first minor axis point 16 and the second minor axis point of the first controllable display area in fig. 5 and 6), the first short axis points of the first patterns 110 are close to each other, and the distances between the second short axis points of any two adjacent first patterns are substantially equal. It can be seen that the first pattern group 14 is composed of a plurality of elliptical and annular first patterns 110, and the sizes of the first patterns 110 are different, the large first patterns 110 are arranged on the radial outer side of the small first patterns 110, and the first short axis points of the first patterns 110 are close to each other, so that the first pattern group 14 is in a horn shape gradually expanding from the small first patterns 110 to the large first patterns 110, and the first patterns 110 are elliptical, so as to enhance the stereoscopic impression of the horn-shaped first pattern group 14, wherein the first pattern 111 forms a horn mouth of the horn-shaped first pattern group 14.

Referring to fig. 8 and 10, the second segment code screen 2 includes a second segment code liquid crystal panel 23, at least a second controllable display area group 24 is disposed in the second segment code liquid crystal panel 23, the second controllable display area group 24 includes an elliptical ring-shaped second controllable display area 25, a major axis of a first reflection 26 (see fig. 11 and 12, the first reflection 26 is an elliptical ring) of the second controllable display area 25 with respect to the first surface 35 of the light processing panel 3 is substantially parallel to a major axis of the first controllable display area 100, an eccentricity of the second controllable display area 25 is substantially equal to an eccentricity of the first controllable display area 100, and a size of the second controllable display area 25 is between a size of the largest first controllable display area 100 and a size of the smallest first controllable display area 100 (the sizes may refer to respective lengths of the major axes).

When the second group of controllable display areas 24 is illuminated, the following pattern is obtained:

referring to fig. 9, 14 and 15, a second pattern group 27 is shown on the mirror image 22, the second pattern group 27 includes an oval ring-shaped second pattern 201, the major axis of the second pattern 201 is substantially parallel to the major axis of the first pattern 110, the eccentricity of the second pattern 201 is substantially equal to the eccentricity of the first pattern 110, and the size of the second pattern 201 is between the size of the largest first pattern 110 (i.e., first pattern 111) and the size of the smallest first pattern 110 (i.e., first pattern 115).

When the first controllable display area group 13 and the second controllable display area group 24 are simultaneously displayed, the first pattern group 14 and the second pattern group 27 are synchronously displayed, the first pattern group 14 and the second pattern group 27 jointly form a display pattern group (see reference numerals 41 and 42 in fig. 15), a projection of the second pattern 201 on a plane where the first display image is located is a second pattern projection, a short axis of the second pattern projection and a short axis of the first pattern 110 are approximately on the same straight line, the second pattern projection intersects at least a part of the first pattern 110, because the first pattern group 14 is horn-shaped as a whole, a central point of the second pattern projection and the first short axis point 16 of the first pattern 111 are respectively located on two sides of a central point of the first pattern 111, and a central point of the first short axis of the second pattern projection and a central point of the second group projection are respectively located on two sides of a central point of the first group 111, the second pattern 201 in the display pattern group is made to look like a sound wave ejected from the horn-shaped first pattern group 14 (the ejection direction is toward the user side), and thus the first pattern group 14 and the second pattern group 27 are combined to form a stereo horn pattern (display pattern group) to be used as the hour meter bezel pattern 42 or the revolution meter bezel pattern 41.

Further, the mirror image 22 and the first display image 11 have a first pitch 30 in the front-rear direction, the first pitch 30 is preferably 12mm to 18mm, and the user sees the combined image 40 formed by the mirror image 22 and the first display image from the front side of the light processing plate 3, wherein the mirror image 22 is closer to both eyes of the user than the first display image 11, and thus the second pattern 201 is closer to both eyes of the user than the first pattern group 14 in the display pattern group, so that the annular second pattern 201 is ejected to the user side as if it were from the trumpet-shaped first pattern group 14, thereby enhancing the stereoscopic effect of the stereoscopic trumpet pattern formed by the first pattern group 14 and the second pattern group 27.

The user is usually in a viewing angle looking at the first displayed image 11, and in this viewing angle, the position relationship between the second pattern 201 and the first pattern group 14 is substantially the same as the position relationship between the second pattern projection and the first pattern group 14, so that the user will see that the second pattern 201 intersects at least a part of the first pattern 110. In the existing single segment code screen, two independent patterns can not be communicated or intersected on the single segment code screen, so that the automobile instrument panel in the application can display the patterns which can not be displayed by the existing single segment code screen.

In a preferred embodiment, referring to fig. 5 to 7, in the first controllable display area group 13, the first short axis points 16 of all the first controllable display areas 100 are at the same point, that is, the first short axis points 16 of all the first controllable display areas 100 are close together, so that the first short axis points 16 of all the first controllable display areas 100 overlap each other, the first controllable display area 100 with the largest size is a first controllable display area 101, all the first controllable display areas 100 except the first controllable display area 101 have first auxiliary notches 17, and the first auxiliary notches 17 are located at the first short axis points 16 of all the first controllable display areas 100, so that the first controllable display areas 100 do not overlap and are not connected with each other.

For convenience of description, taking the number of the first controllable display areas 100 as five as an example, the sizes are sequentially from large to small: a first controllable display area 101, a second controllable display area 102, a third controllable display area 103, a fourth controllable display area 104, and a fifth controllable display area 105, a second short axis point 151 of the first controllable display area, a second short axis point 152 of the second controllable display area, a second short axis point 153 of the third controllable display area, a second short axis point 154 of the fourth controllable display area, a second short axis point 155 of the fifth controllable display area, the distances between two adjacent second short axis points are equal, wherein the first controllable display areas 100 from the second to the fifth have first auxiliary notches 17, the size of the first auxiliary notch 17 of the second controllable display area 102 is the largest, the size of the first auxiliary notch 17 of the third controllable display area 103 is the next, the size of the first auxiliary notch 17 of the fourth first controllable display area 104 is then the size of the first auxiliary notch 17 of the fifth first controllable display area 105 is the smallest, so that the first short axis point 16 position of the first controllable display area 101 of the first controllable display area group 13 covers the first short axis point 16 positions of the second first controllable display area 102, the third first controllable display area 103, the fourth first controllable display area 104 and the fifth first controllable display area 105. Thus, when the first controllable display area group 13 is lit, the first pattern group 14 is:

referring to fig. 4, the first minor axis point 16 of each of the first patterns 110 is at the same point, all the first patterns 110 except for the first pattern 111 have first notches (i.e., the second pattern 112, the third pattern 113, the fourth pattern 114 and the fifth pattern 115 have first notches corresponding to the first auxiliary notches 17), and the first minor axis points of the first patterns 110 are located at corresponding first notch positions, so that the first patterns 110 do not intersect with each other. So that the first pattern group 14 is horn-shaped.

In a preferred embodiment, referring to fig. 5 and 6, there is a gradual width (radial direction) across the first controllable display area # 101, with the radial width of the first stub point 16 of the first controllable display area # 101 being the largest and the radial width of the second stub point 151 of the first controllable display area # being the smallest. The width of the first controllable display area 101 with gradual change is: the radial width of the first controllable display region 101 gradually becomes smaller from the first minor axis point 16 of the first controllable display region 101 to the second minor axis point 151 of the first controllable display region along the circumferential direction of the first controllable display region 101.

Obviously, when the first controllable display area No. one 101 is lighted, the first pattern No. one 111 has a gradually changing pattern width, and the radial width of the first short axis point is the largest, and the radial width of the second short axis point is the smallest. Under the user's perspective, the first pattern 111 in the horn-shaped first pattern group 14 is the largest, giving the user the illusion that the first pattern 111 is closest to the user, and the width of the first short axis point of the first pattern 111 is the largest, giving the user the illusion that the first short axis point in the first pattern 111 is closest to the user, and the second short axis point in the first pattern 111 is far away from the user, enhancing the effect that the first pattern group 14 is in the inclined horn shape, and thus enhancing the stereoscopic effect of the first pattern group 14.

In a preferred embodiment, the number of the first patterns 110 in the first pattern group 14 is five, the major axis dimension of the second controllable display area 25 is the same as the major axis dimension of the second first controllable display area 102 (the difference between the major axis dimension of the second controllable display area 25 and the major axis dimension of the second first controllable display area 102 is not more than 2mm), the dimension of the second pattern 201 is substantially the same as the dimension (major axis dimension) of the first pattern 110 with the second largest dimension (the second first pattern 112) (the difference between the major axis dimension of the second pattern 112 and the major axis dimension of the second pattern 201 is less than 2mm), the radial width of the second pattern 201 is kept unchanged, and the radial width of the second pattern 201 is substantially the same as the radial width of the first minor axis point of the first pattern 111. When the first pattern group 14 and the second pattern 201 are displayed synchronously, the second pattern 201 looks like a sound wave ejected from the first pattern group 14 (horn shape), and the major axis dimension of the second pattern 201 is approximately the same as the major axis dimension of the second first pattern 112, so that the sound wave has a sufficiently large dimension, thereby enhancing the expression effect of the stereo horn pattern formed by the first pattern group 14 and the second pattern group 27 (see fig. 15).

In a preferred embodiment, referring to fig. 10 and 13, the second controllable display region group 24 further includes a plurality of third controllable display regions, each of the third controllable display regions is in a bar shape, a length direction of each of the third controllable display regions is parallel to a short axis direction of the second controllable display region 25, each of the third controllable display regions includes a first end 312 and a second end 311, the plurality of third controllable display regions are divided into a first third controllable display region group 33 corresponding to a part of an inner contour line of the second controllable display region 25 and a second third controllable display region group 32 corresponding to a part of an outer contour line of the second controllable display region 25, wherein the third controllable display regions in the first third controllable display region group 33 are the first third controllable display regions 302, the third controllable display regions in the second third controllable display region group 33 are the second third controllable display regions 301, the partial inner contour and the partial outer contour are located on either side of the long axis of the second controllable display area 25. A first end 312 of the third controllable display region (the first controllable display region 302 or the second controllable display region 301) corresponds to the first short axis point 252 of the second controllable display region, a second end 311 of the third controllable display region corresponds to the second short axis point 251 of the second controllable display region, and a direction from the first short axis point 16 to the second short axis point is the same as a direction from the first end 312 to the second end 311.

Thus, referring to fig. 14, when the second controllable display area group 24 is lit, the second pattern group 27 further includes a plurality of third patterns 203, the third patterns 203 are in a long shape, a length direction of the third patterns 203 is parallel to a short axis direction of the second pattern 201, the third patterns 203 include a first end 312 and a second end 311, the plurality of third patterns 203 are divided into a first third pattern group 205 corresponding to a partial inner contour of the second pattern 201 and a second third pattern group 204 corresponding to a partial outer contour of the second pattern 201, and the partial inner contour and the partial outer contour are respectively located at two sides of a long axis of the second pattern 201.

Further, the first number third controllable display region group 33 is located at the radial inner side of the second controllable display region 25, the second end 311 of each first number third controllable display region 302 in the first number third controllable display region group 33 is closer to the partial inner contour line of the second controllable display region 25 than the first end 312 thereof, in the first number third controllable display region group 33, each first number third controllable display region 302 is sequentially arranged along the direction of the partial inner contour line, and the first ends 312 of all first number third controllable display regions 302 are sequentially connected to form a first curve, and the direction of the first curve is the same as the direction of the partial inner contour line.

When the first third controllable display region group 33 is lit, the first third pattern group 205 is located radially inward of the second pattern 201, the second end (corresponding to the second end 311 of the third controllable display region) of each third pattern 203 in the first third pattern group 205 is closer to the partial inner contour line of the second pattern 201 than the first end (corresponding to the first end 312 of the third controllable display region), in the first third pattern group 205, each third pattern 203 is sequentially arranged along the partial inner contour line direction, and the first ends of all third patterns 203 are sequentially connected to form a first curve, and the first curve has the same direction as the partial inner contour line. It can be seen that the first and second pattern groups 205 are arranged along the inner contour of the second pattern 201, so that the first and second pattern groups 205 are as if the second pattern 201 were ejected from the first pattern group 14, thereby enhancing the expression effect of the stereo horn pattern.

The second controllable display region group 32 is located outside the second controllable display region 25, the second end 311 of each second controllable display region 301 in the second controllable display region group 32 is closer to the partial outer contour line of the second pattern 201 than the first end 312 thereof, in the second controllable display region group 32, each second controllable display region 301 is sequentially arranged along the partial outer contour line direction, the first ends 312 of all the second third controllable display regions 301 are sequentially connected to form a second curve, and the direction of the second curve is the same as the direction of the partial outer contour line.

The second third pattern group 204 is located outside the second pattern 201, a second end (corresponding to the second end 311 of the third controllable display region) of each third pattern 203 in the second third pattern group 204 is closer to the part of the outer contour line of the second pattern 201 than a first end (corresponding to the first end 312 of the third controllable display region) thereof, in the second third pattern group 204, each third pattern 203 is sequentially arranged along the part of the outer contour line direction, the first ends of all the third patterns 203 are sequentially connected to form a second curve, and the direction of the second curve is the same as the direction of the part of the outer contour line. Similarly, the second and third pattern groups 204 are just like a partial wake formed when the second pattern 201 is ejected from the first pattern group 14, and the first and third pattern groups 205 and 204 jointly form a wake formed when the second pattern 201 is ejected from the first pattern group 14, so that the three-dimensional horn pattern jointly formed by the first pattern group 14 and the second pattern group 27 has a stronger expression effect.

In a preferred embodiment, referring to fig. 10 and 14, the second controllable display area group 24 further includes a plurality of digital controllable display areas 28, and the plurality of digital controllable display areas 28 are located at the radial outer side of the second third controllable display area group 32 and are uniformly distributed from small to large along the arrangement direction of the second third controllable display area group 32 (the arrangement direction of each second third controllable display area 301 in the second third controllable display area group 32). When the digitally controllable display region 28 is illuminated, a digital pattern 202 is formed on the mirror image 22, and thus the second pattern group 27 further includes a plurality of digital patterns 202, and the plurality of digital patterns 202 are located radially outside the second third pattern group 204 and are uniformly distributed from small to large (according to the value of each digital pattern 202) along the arrangement direction of the second third pattern group 204.

Referring to fig. 15, if the stereo horn pattern constitutes the revolution meter bezel pattern 41, the number patterns 202 may be 0, 1, 2, 3, 4, 5, 6, 7, 8; if the stereo horn pattern constitutes the hour meter bezel pattern 42, the plurality of digital patterns 202 may be 0, 20, 40, 60, 80 … … 200, 220.

Referring to fig. 14, the third pattern 203 in the second and third pattern groups 204 is partially or entirely lit according to the vehicle speed or the engine speed. Taking the stereo horn pattern as an example to form the dial pattern 42 of the hour meter, the vehicle speed is raised from "0", the second third controllable display area group 32 is lit from the first second third controllable display area 301 at one end thereof, the second third controllable display area 301 corresponds to the digital controllable display area 28 of 0, when the vehicle speed reaches 20, the second third controllable display area group 32 is lit between the digital controllable display area 28 of "0" and the digital controllable display area 28 of "20", and thus the user can see that the number of lit third patterns 203 in the second third pattern group 204 is correlated with the positive vehicle speed. So that the current vehicle speed or engine speed can be better represented using the third pattern group 204 No. two.

In a preferred embodiment, referring to fig. 3 and 8, the first controllable display area group 13 and/or the second controllable display area group 24 further include a segment code value controllable display area group 20, a second auxiliary notch 18 (see fig. 6 and 7) is provided on part or all of the first controllable display area 100 to avoid the segment code value controllable display area group 20, and a fourth notch 31 (see fig. 13) is provided on the second controllable display area 25 to avoid the segment code value controllable display area group 20. Taking the stereo horn pattern to form the dial ring pattern 42 of the speedometer as an example, the segment code numerical value controllable display area group 20 can display the segment code numerical value pattern 200 of the current vehicle speed, and the second auxiliary notch 18 and the fourth notch 31 are arranged, so that the segment code numerical value pattern 200 cannot be overlapped with other patterns, and a user can obtain the clear and non-interference segment code numerical value pattern 200 to know the current vehicle speed. Thus, the first pattern group 14 and/or the second pattern group 27 in the stereo speaker pattern further include the segment code number pattern 200, a second gap (corresponding to the second auxiliary gap 18 on the first controllable display area 100) is provided on part or all of the first pattern 110 to avoid the segment code number pattern 200, and a third gap 29 (corresponding to the fourth gap 31 on the second controllable display area 25) is provided on the second pattern 201 to avoid the segment code number pattern 200.

Preferably, referring to fig. 6 and 7, the second auxiliary notch 18 is located at the second short axis point position of the first controllable display area 100, and the fourth notch 31 is located at the second short axis point 251 position of the second controllable display area. Thus, on the first pattern group 14 and the second pattern group 27, the second notch is located at the second short axis position of the first pattern 110, and the third notch 29 is located at the second short axis position of the second pattern 201 (see fig. 14). The segment code numerical pattern 200 is located at the third notch 29 and the second notch, and on the stereo horn pattern, the segment code numerical pattern 200 is integrally arranged opposite to the plurality of digital patterns 202, so that the stereo horn pattern is integrally more coordinated.

In addition, referring to fig. 13, due to the existence of the fourth gap 31, a fourth auxiliary gap 34 is disposed on the first third controllable display area group 33, and the fourth auxiliary gap 34 is used to avoid the segment code value controllable display area group 20. That is, a portion of the first controllable display area 302 in the first third controllable display area group 33 is removed to avoid the segment code value controllable display area group 20.

In a preferred embodiment, referring to fig. 3, 8, and 15, the first controllable display region group 13 and the second controllable display region group 24 are both two in number and are respectively disposed approximately bilaterally symmetrically, the short axis direction of the first controllable display region 100 in the left first controllable display region group 13 is from the upper right to the lower left, and the short axis direction of the first controllable display region 100 in the right first controllable display region group 13 is from the upper left to the lower right. Two first pattern groups 14 and two second pattern groups 27 are provided, respectively, substantially bilaterally symmetrically, to serve as a dial pattern of a revolution counter and a chronometer on an instrument panel, respectively, and a short axis direction of the first pattern 110 on the left side is from upper right to lower left, and a short axis direction of the first pattern 110 on the right side is from upper left to lower right. The user is caused to generate the illusion that both the revolution meter bezel pattern 41 and the hour meter bezel pattern 42 are ejected to the middle of the both, enhancing the display effect of the combined image 40.

In a preferred embodiment, the second pattern 201 exhibits a gradient color. Referring to fig. 9, taking the revolution meter bezel pattern 41 as an example, the second pattern 201 may be a blue-red gradient, a portion of the second pattern 201 corresponding to the numbers 0-6 in the digital pattern 202 is blue, a portion of the second pattern 201 corresponding to the numbers 7-8 in the digital pattern 202 is red, and a portion of the second pattern 201 corresponding to the numbers 6-7 in the digital pattern 202 is a blue-red gradient.
