Specific embodiment

Fig. 1 shows the display equipment 100 in the embodiment of the present invention.Show that equipment 100 may include display module 110, optics Modulator 120, eye movement tracing module 130 and controller 140.Controller 140 can be coupled to eye movement tracing module 130 and display mould Block 110.

In certain embodiments, display module 110 can be but be not only restricted to Organic Light Emitting Diode (organic Light emitting diode, OLED) display module, quantum light emitting diode (quantum light emitting Diode, QLED) display module, micro-led (mini-LED) display module, micro- light emitting diode (micro-LED) At least one of display module and liquid crystal display (LCD) module.

Optics modulator 120 may be disposed at display module 110 on emit optics modulator 120 by display module 110 Light modulate to corresponding direction.In certain embodiments, optics modulator 120 includes but is not limited to lenticular film (lenticular film), liquid crystal graded index eyeglass (liquid crystal gradient index lenses), view At least one of poor grating (parallax barriers) and liquid crystal parallax grating.

Fig. 2 shows the viewing graphic pattern of display module 110 and optics modulator 120 in the embodiment of the present invention.In Fig. 2, Display module 110 includes multiple pixels, and the pixel may be partitioned into 9 groups (P1 to P9), 9 different viewing angles are presented Image.Such as the image of pixel P1 the first viewing angle for rendering, the image of pixel P2 the second viewing angle for rendering, The rest may be inferred.Different group pixels are arranged parallel to each other in Fig. 2.Such as viewing line PL1, PL2 and PL3 be parallel to each other and main difference It is formed by pixel P4, P5 and P6.Therefore when the mobile viewing location of viewer, viewer can be seen pixel P4 presentation image, The image that the image and pixel P6 that pixel P5 is presented are presented.

The present invention is not limited to provide 9 kinds of different perspectivess by display module 110.In some embodiments of the invention, it shows Module 110 can provide less or compared with multi-angle of view, and can be provided according to the specification of optics modulator 120 and display module 110 different Pattern of pixels.In addition in Fig. 2, the inclination angle X between optics modulator 120 and display module 110, which can be greater than 0 degree, makes difference The image energy of viewing angle is spread to lower the sudden change between different perspectives.That is inclination angle X can determine according to system requirements It is fixed, and in certain embodiments can be 0 degree.

Optics modulator 120 can guide the light of pixel emission to corresponding direction.In the present embodiment, optics modulator The sequence of 120 view directions modulated can be opposite with the viewing sequence of line of display module 110 is set to.Such as in display mould Block 110, the viewing line that pixel P1 to pixel P9 is formed are set as by left-to-right, but practical when viewer moves from left to right The meeting seen is sequentially to be formed by image to pixel P1 by pixel P9 due to the modulation of optics modulator 120.

Therefore if viewer sees display module 110 by point A, viewer can see provided by pixel P1 from his right eye Image, and image provided by pixel P4 is seen from his left eye.Similarly, if viewer sees display module 110 by point B, Viewer can see image provided by pixel P6 from his right eye, and see image provided by pixel P9 from his left eye.

Since the right eye and left eye of viewer can receive the image of different viewing angles, so display module 110 is able to achieve 3D visual effect.Viewing angle provided by pixel P1 to P9 is pre-determined and limited in the prior art.Therefore resonable In the case of thinking, viewer can be seen image provided by pixel P1 as right eye and see image provided by pixel P4 as left eye, Use correctly realization 3D visual effect.If however viewer's torticollis (yaw) or shake the head (roll) when, viewer can be from his right side Image provided by pixel P2 is arrived soon, and sees image provided by pixel P3 from his left eye.In this example due to Pixel P2 and P3 provide viewing angle may be too close and inconsistent and 3D visual effect can not be formed, viewer can feel Incorrect depth information and feel dizzy.

Limited viewing need not be concerned about in order to improve 3D visual effect and viewer be allowed easily to watch display equipment 100 Angle, display equipment 100 can use the position of the tracking viewer's eyes of eye movement tracing module 130.Controller 140 will define simultaneously Eye across the position of viewer's eyes is generated to eye straight line, and according to multiple viewing locations on eye to eye straight line The image data of pixel in display module 110.Therefore display equipment 100 can be automatic vertical to present with better quality and less limitation The visual effect of body.

Fig. 3 shows that the embodiment of the present invention shows the viewing situation of equipment 100.In Fig. 3 viewer V slightly rotary head (or Or yawed)) viewing display equipment 100.Viewer V is given in order to provide image, eye movement tracing module 130 can detect viewer V Right eye and left eye position.Controller 140 can export the central location VC of viewer V eyes according to the position of viewer's V eyes.

Next referring to Fig. 1, controller 140 can be in the central location for defining corresponding viewer's eyes on display module 110 The central incident line CPL1 of VC.Central incident line CPL1 can indicate to penetrate central position of the optics modulator 120 from viewer's eyes Set the center pixel that VC should be seen that.Fig. 4 shows the central incident line on display module of the embodiment of the present invention 110.

Since central incident line CPL1 is also related to the placement location of optics modulator 120 and display module 110, controller 140 can be according to parameter definition center incident line CPL1 relevant to optics modulator 120 and display module 110.For example, the ginseng Number can include lens spacing, the curvature of optics modulator 120 and the optics modulator 120 and display module of optics modulator 120 At least one of inclination angle between 110.Light between display module 110 and optics modulator 120 in some examples simultaneously Learning gap can be fixation.These parameters can determine when manufacture in certain embodiments, and can be recorded in the memory of controller 140 It is interior.By the required parameter, controller 140 can export central incident line CPL1 according to the central location VC of viewer's eyes.

In certain embodiments for the central incident line CPL1 of more accurate export, controller 140 can also be used timing to lead Parameter out.Such as the parameter that related and controller 140 uses to optics modulator 120 and display module 110 can further include seeing The distance between the person's of seeing eyes and eye-angle deviant.In embodiment, eye-angle deviant can be display module 110 Horizontal direction and viewer eye to the angle between eye straight line.Therefore in a manufacturing process caused by error and certain systems Making error caused by implied terms in program can be corrected.

The pixel of display module 110 is set to repeat patterns block in certain embodiments, and controller 140 can be found pair Answer a plurality of central incident line of the different central incident lines.Such as shown in Figure 3 and Figure 4, controller 140 can be directed to pattern block B1 Central incident line CPL1 is exported, and exports central incident line CPL2 for pattern block B2.

After central incident line CPL1 export, controller 140 can more be directed to the pixel of pattern block B1, according to the reference of pixel The distance between point and the corresponding central incident line export each modulator to pixel (modulator-to-pixel) deviant.I.e. Modulator can be exported to pixel offset value for each pixel of pattern block B1.The reference of pixel in certain embodiments Point can be but be not only restricted to the central point of such as pixel.

According to the modulator of the pixel of pattern block B1 to pixel offset value, controller 140 can export corresponding pattern block Viewing location on the eye of the pixel of B1 to eye straight line EL.I.e. for each pixel of pattern block B1, controller 140 all can The viewing location on eye to eye straight line EL is exported, may be viewed by the pixel from the viewing location.Such as controller 140 in Fig. 3 The viewing location VPA of respective pixel PA can be exported, and the viewing location VPB of respective pixel PB can be exported.In this example as Plain PA will show from the viewing location VPA image data that should be seen and pixel PB and will show from viewing location VPB The image data that should be seen.

Since eye to eye straight line EL is defined by the connecting line extended between viewer V eyes, when viewer V torticollis or Eye can change to eye straight line EL when shaking the head, therefore by the viewing location defined on eye to eye straight line EL, produced by controller 140 And the practical view direction of viewer V can be matched in the image data presented in pixel, lower the defect that viewer sees and increasing Add visual quality.

Scene image to be shown can be generated using biggest advantage of light track algorithm in the present embodiment.It controls in this example Device 140 can according to viewing location export respective pixel light vector (ray vectors), and by along institute derived from light to The luminous intensity (light intensities) in sample scene is measured to generate the image data of pixel.

Fig. 5 shows the scene S1 to be shown of display module of the embodiment of the present invention 110.In Fig. 5, scene S1 energy to be shown It is formed by multiple voxels (voxels), and each voxel includes colouring information and luminance information.In this example, if viewing location VPA corresponds to light vector RA, and controller 140 will check voxel along light vector RA.Such as light vector RA can lead in Fig. 5 It crosses voxel VX1 and VX2 controller 140 is enable to handle voxel VX1 and VX2 and pixel PA and be able to display voxel VX1 and VX2.In Controller 140 can generate the image data of pixel PA by color combining and luminance information in some embodiments, wherein color And luminance information is stored in multiple pixels with suitable weight.

However in some embodiments of the invention, scene to be shown can be formed with different configuration, such as can be by multiple depths Degree face (depth planes) forms scene, and each depth plane can include with corresponding color information, transparence information and bright Spend multiple points of information.Fig. 6 shows the scene S2 to be shown of display module of the embodiment of the present invention 110.Scene S2 can be by depth Face D1 to D3 is formed.If viewing location VPA corresponds to light vector RA in Fig. 6, controller 140 will be checked along light vector RA Point on depth plane D1 to D3, and believed according to the colouring information, transparence information and brightness recorded on the point of depth plane D1 to D3 Cease the color and brightness to determine pixel PA.

In certain embodiments, each depth plane D1 to D3 can have transparent region and opaque region.Opaque region Can have the surface 2D or 3D, and the face that rear will be obstructed.Such as depth plane D1 may include the object of prospect and depth plane D3 can be wrapped Include the object of background.Therefore the object for being shown in depth plane D1 can obstruct the object for being shown in depth plane D3.Due to depth plane It constructs comparatively simple, it is possible to be generated in real time by 3D rendering engine.

Because showing that equipment 100 can use eye movement tracing module 130 to track the position of viewer's eyes and be directed to each picture Element generates image data according to the viewing location on eye to eye straight line EL, and the image that display module 110 is presented will meet viewer Viewing location and view direction.Even if viewer's torticollis or when shaking the head, viewer can also be seen with corresponding viewing angle forever See image.In in the prior art, only image can be presented for specific viewing angle in display equipment, so when viewer's torticollis or shaking Viewer may can be appreciated that the image of inconsistent viewing angle when head, therefore 3D visual effect may be very poor.Therefore compared to existing There is technology to show that equipment 100 can provide preferable visual quality, when viewer's torticollis or benefit of the invention can be more when shaking the head Obviously.

Viewing angle to be shown, and the prior art can be determined according to eye to eye straight line in real time additionally, due to controller 140 Pre-determined and limited viewing angle can only be provided, so display equipment 100 can provide wider viewing angle compared with the prior art Degree.Show that image is presented just for limited and pre-determined viewing angle in equipment in the prior art, so when viewer moves When dynamic, viewer will be appreciated that the image of repetition viewing angle.Using display equipment 100 of the invention, controller 140 can be generated The image of the different viewing angles of corresponding viewer position, therefore viewer can see wider viewing angle under same scene.

In addition in some embodiments, if eye movement tracing module 130 detects the change of viewer's eyes position, controller 140 can determine that whether the change of position is greater than critical value.If the change of position is fairly small and is no more than critical value, controller 14 New image data can not be generated；If the change of position is greater than critical value, controller 140 will generate corresponding viewer's eyes position The new image data set, i.e., when the change of eye position degree appreciable greater than viewer, display equipment 100 can be according to sight The new eye position of the person of seeing generates new image data, when the change of eye position is seldom if lower operand.

In the present embodiment, although display equipment 100 is to provide different viewings by tracking eyes for a viewer The image of angle is to generate 3D visual effect, if enough close to the first viewer and sharing identical eye to eye straight line, the second viewing The image that person can also provide according to display equipment 100 feels 3D visual effect.
