In a second embodiment of the present application, please refer to fig. 3 and fig. 1 and 2, where fig. 3 is a flowchart illustrating a step of a method for controlling an intelligent movable local touch dimming window according to the second embodiment of the present application. As shown in the figure, the method S for controlling an intelligent movable area-touch dimming window of the present embodiment is based on the control principle of the intelligent movable area-touch dimming window of the first embodiment, and includes the following steps S1-S4, where:

in step S1, a first gesture is formed on the touch screen 3. A first touch signal is generated on the touch screen 3, and the first touch signal corresponds to a first gesture of the user on the touch screen 3 and is transmitted to the transparent dimming function 4.

Specifically, a finger of a user touches any area of the cover glass 2 and slides to form a first gesture in a corresponding area of the touch screen 3, the touch chip 7 of the touch screen 3 recognizes that a touch operation is performed on the surface of the touch screen 3 to generate a first touch signal, and the touch chip 7 sends the first touch signal to the display chip 6 of the dimming function 4 through USB or RS232 communication.

In the present embodiment, the transparency levels of the dimming function 4 are sequentially classified into 0 to 5 levels, wherein the light shielding degrees of the transparencies of the 0 to 5 levels are sequentially decreased. Level 0 is the black screen/opaque state for the highest shade, and level 5 is the white screen/transparent state for the lowest shade. When the overall transparency level of the dimming function part 4 is in any one of the transparency levels of 0 to 2, the track of the first gesture is white, and when the overall transparency level of the dimming function part 4 is in any one of the transparency levels of 3 to 5, the track of the first gesture is black, so that the track of the first gesture is in sharp contrast with the overall transparency of the dimming function part 4, and a user can observe the track of the first gesture conveniently.

In step S2, a dimming region is formed. The transparent dimming function 4 recognizes the first touch signal, determines whether an area formed by the first gesture is a closed area, and displays a dimming area corresponding to the first touch signal if the area is the closed area.

Specifically, the display chip 6 of the transparent dimming function 4 recognizes the first touch signal and determines whether the area formed by the first gesture is the closed area, in this embodiment, because the operation habits of different users are different, it is difficult to draw a closed area on the touch screen 3 by sliding a finger at one time, and therefore the transparent dimming function 4 determines whether the area formed by the first gesture is the closed area by determining whether the area formed by at least one first gesture on the touch screen 3 is the closed area. If the area formed by the first gesture is a closed area, the transparent dimming function 4 is controlled to display a dimming area corresponding to the first touch signal, that is, the dimming area having the same position, shape and size as the area formed by the first gesture is displayed on the transparent dimming function 4. After the transparent dimming function 4 displays the dimming region, the initial transparency level of the dimming region is 0 level, but not limited thereto.

Preferably, when there is a gap in at least one of the regions formed by the first gestures, for example, a gap due to an irregular user operation, the display chip 6 of the transparent dimming function 4 recognizes the first touch signal, and then fills up the gap to form a closed region by the first gesture, and determines that the region formed by the first gesture is the closed region, that is, the dimming region desired by the user. If the transparent dimming function cannot fill up the gap, for example, the gap is large or the user touches the touch screen 3 accidentally, the first gesture is deleted after a period of time, and specifically, the first gesture/scribe line on the touch screen 3 automatically disappears according to a 15s no-operation principle, that is, the touch screen 3 does not operate within 15 s.

Preferably, when the transparent dimming function 4 determines that at least one area composed of the first gesture is a closed area, the redundant drawn lines outside the closed area disappear, specifically, when the user draws a closed area by sliding a finger on the touch screen 3, the redundant drawn lines around the closed area composed of the first gesture usually exist due to the irregular drawn lines drawn by the user, for example, two lines that are excessive due to the intersection of the two drawn lines, the drawn lines that do not form the closed area, and the like, and after the transparent dimming function 4 determines that the area composed of the first gesture is the closed area, the redundant drawn lines automatically disappear.

In step S3, a second gesture is formed on the touch screen 3. The touch screen 3 generates a second touch signal corresponding to a second gesture of the user on the touch screen 3 and transmits the second touch signal to the transparent dimming function 4.

Specifically, a user touches any position of the cover glass 2 by a finger to form a second gesture at a corresponding position of the touch screen 3, the touch chip 7 of the touch screen 3 recognizes that a touch operation is performed on the surface of the touch screen 3 to generate a second touch signal, and the touch chip 7 sends the second touch signal to the display chip 6 of the dimming function 4 through USB or RS232 communication. The second gesture may be a single point of the user's finger on the touch screen 3, or may be a sliding of the user's finger on the touch screen 3, but is not limited thereto.

Step S4, adjusting the transparency of the dimming region. The transparent dimming function 4 recognizes the second touch signal, determines whether the second gesture is in the dimming area, and if so, adjusts the transparency of the dimming area.

Specifically, the display chip 6 of the transparent dimming function 4 recognizes the second touch signal, determines whether the second gesture is in the dimming area, and if so, adjusts the transparency of the dimming area. The transparent dimming function 4 increases the transparency level of the primary dimming region until the transparency level of the dimming region reaches 5 levels each time the second gesture is determined to be within the dimming region, so as to implement any dimming of the dimming region, and the interval between two adjacent determinations that the second gesture is within the dimming region is preferably greater than 500ms, that is, the interval between two adjacent determinations that the transparency of the dimming region is greater than 500 ms. When the user wants to cancel the dimming area, the user can press the dimming area for more than 5 seconds, and the transparency level of the current transparent dimming function 4 is restored to the dimming area.

In this embodiment, if the second gesture is in the dimming area and is dragged in a sliding manner, the dimming area is adjusted to the dragging position, for example, the incident angle of sunlight also changes during the operation of the train, at this time, the dimming area previously set by the user may not block the current sunlight, at this time, the finger of the user clicks on any position of the dimming area, and then the sliding dragging is performed, so that the dimming area is dragged to a position desired by the user, thereby improving the riding experience and satisfaction of the user.

In this embodiment, if the transparent dimming function 4 determines that the second gesture is not in the dimming region and the region formed by the second gesture is a closed region, it is determined that the user wants to add a new dimming region, and a dimming region corresponding to the second touch signal is displayed on the transparent dimming function 4, that is, a dimming region having the same position, shape and size as the region formed by the second gesture is displayed on the transparent dimming function 4, that is, the second gesture is regarded as the first gesture and is processed according to the first gesture processing method, so that the plurality of dimming regions are simultaneously divided on the transparent dimming function 4 to perform individual dimming on each dimming region, thereby meeting the dimming requirements of different passengers.

To sum up, the application provides an intelligent movable regional touch dimming car window and a control method thereof, which are mainly applied to a side window of a vehicle, wherein a touch screen and a dimming function part are arranged on a cover glass, a first gesture of a user on the touch screen forms a closed region to control the dimming function part to generate a corresponding dimming region, a second gesture of the user on the touch screen is positioned in the dimming region to control the transparency of the dimming region, so that the cover glass/the dimming function part can be arbitrarily divided into the closed region to perform independent dimming, the transparency of the other region cannot be influenced when the closed region is dimmed, and the dimming requirements of different passengers can be met.
