Description

[0001] The present application belongs to the technical field of naked eye 3D display, and particularly relates to a method for reducing 3D crosstalk and a stereoscopic image display device.

[0002] With the rapid development of stereoscopic display technology, one of the mainstream naked eye three dimension (3D) display technologies is a parallax-based stereoscopic display technology, mainly including two ways: grating type and lens array type. With the development of liquid crystal technology, liquid crystal materials are widely used in various fields. Liquid crystal grating is an active grating, which can realize three-dimensional stereoscopic display. Please refer to Figure 1 It is a principle diagram for 3D display using liquid crystal grating. The liquid crystal grating 2 distributed at intervals in the light transmission region is arranged in front of the display panel 1, and the liquid crystal grating 2 is a "parallax barrier". The image displayed by the display panel 1 includes left-eye image information (L) and right-eye image information (R). In the 3D display mode, the left-eye image information and the right-eye image information of the display panel 1 are selectively separated by the liquid crystal grating 2, so as to achieve the effect of 3D display.

[0003] However, in the stereoscopic image display device, a luminance difference may be generated based on different positions in the screen.

[0018] First, the method for reducing 3D crosstalk is described in detail, please refer to Figure 2A , Figure 2A The flowchart of the method for reducing 3D crosstalk provided by the embodiment of the application comprises:

[0019] 201, determining the left spatial distance of each prism column in the 3D prism grating to the left eye of the viewer and the right spatial distance to the right eye of the viewer;

[0020] Crosstalk is a very important concept in the field of 3D display, which can be defined as the phenomenon that the view of a non-viewing channel enters the viewing channel due to incomplete view separation. Crosstalk will cause ghosting, contrast reduction, etc. in stereoscopic images, and it is one of the most important factors affecting image quality and viewing comfort in 3D display. In actual application, when the viewer watches a large-screen naked-eye 3D screen, he or she will encounter the phenomenon that the screen brightness is not the same, that is, some areas are bright and some areas are dark. Therefore, the application provides a method for reducing 3D crosstalk. After a hemispherical 3D prism grating containing a plurality of continuous prisms arranged uniformly is added to the 3D screen, the way of pixel light emission on the screen surface is adjusted. It should be noted that each prism (also referred to as a strip) corresponds to a light intensity parameter, and the pixels corresponding to each prism are compensated through the light intensity parameter.

[0021] It should be noted that the light intensity transmitted to the left eye and the right eye of the viewer is different for each strip, so the light intensity transmitted to the two eyes respectively for each strip is obtained. First, the left spatial distance of each prism column in the 3D prism grating to the left eye of the viewer and the right spatial distance to the right eye of the viewer are determined. Specifically, the position coordinates of each prism column on the screen in the 3D prism grating are established with the left eye of the viewer as the origin; then the first left spatial distance is determined according to the position coordinates of the first prism column, and the specific calculation formula is: Wherein, r represents the first left spatial distance, which is the spatial distance from the first prism column to the left eye of the viewer, the first prism column is any prism column of the prism columns in the 3D prism grating, and (x, y, z) represents the position coordinates of the first prism column. Similarly, the spatial distance from the first prism column to the right eye of the viewer, i.e. the first right spatial distance, is calculated.

[0022] Therefore, the corresponding left spatial distance and right spatial distance are calculated for each prism column in the above manner.

[0023] 202、calculating left light intensity of the first prism column to the left eye of the viewer according to the first left spatial distance, and calculating right light intensity of the first prism column to the right eye of the viewer according to the first right spatial distance;

[0024] After obtaining the first left spatial distance and the first right spatial distance, calculating left light intensity of the first prism column to the left eye of the viewer according to the first left spatial distance, and calculating right light intensity of the first prism column to the right eye of the viewer according to the first right spatial distance.

[0025] Specifically, the left light intensity is calculated by the following formula:

[0026] u=a0*exp(jkr) / r;

[0027] k=2π / λ;

[0028] wherein, the u is used to represent the left light intensity, the a0 is a standard coefficient, the r is used to represent the first left spatial distance, the j is used to represent complex amplitude, and the λ is used to represent wavelength, and it is to be noted that the wavelength is the wavelength of visible light.

[0029] Similarly, the right light intensity of the first prism column to the right eye of the viewer can be calculated.

[0030] 203、calculating a compensation coefficient of the left eye corresponding to the first prism column according to the left light intensity, and calculating a compensation coefficient of the right eye corresponding to the first prism column according to the right light intensity;

[0031] After obtaining the left light intensity and the right light intensity, calculating a compensation coefficient of the left eye corresponding to the first prism column according to the left light intensity, and calculating a compensation coefficient of the right eye corresponding to the first prism column according to the right light intensity. Specifically, it includes: calculating a left light intensity mean value according to the left light intensity of each prism column to the left eye of the viewer; calculating the compensation coefficient by the following formula: k=U_mean / U; wherein, the k is used to represent the compensation coefficient, the U_mean is used to represent the mean value of the left light intensity, and the U is used to represent the left light intensity of the first prism column to the left eye of the viewer. For example, U1, U2…Un are the left light intensity of each prism column to the left eye of the viewer, and U_mean=(U1+U2…+Un) / n.

[0032] Similarly, the right eye compensation coefficient corresponding to the first prism column can also be determined.

[0033] 204、compensating the pixel corresponding to the first prism column according to the compensation coefficient of the left eye and the compensation coefficient of the right eye, so as to reduce 3D crosstalk.

[0034] After the compensation coefficient of the left eye and the compensation coefficient of the right eye are determined, the pixels corresponding to the first prism column are compensated according to the compensation coefficient of the left eye and the compensation coefficient of the right eye, so as to reduce 3D crosstalk. Specifically, the output brightness of the pixels corresponding to the first prism column after reducing crosstalk is calculated according to the compensation coefficient of the left eye and the compensation coefficient of the right eye respectively; the output brightness value of the first prism column is converted into a gray value, so as to determine the gray value of each pixel corresponding to the first prism column after reducing crosstalk, and then the screen is driven to display, wherein the specific way of converting into a gray value is to convert the output brightness value of the first prism column into the gray value according to the mapping relationship between the brightness of the display and the input gray scale, and the input gray scale is a 0-255 gray scale image of the display.

[0035] For better understanding of the present application, please refer to Figure 2B A possible background light intensity change diagram for double-eye viewing provided by the embodiment of the present application is shown in the figure, two curves in the figure are obtained by formula calculation, the dashed line represents the background light intensity seen by the right eye, and the solid line represents the background light intensity seen by the left eye. In the figure, the two curves coincide at 110 in the horizontal axis direction. The solid line is multiplied by the compensation coefficient, and the dashed line is also multiplied by the compensation coefficient, so that the difference between the two lines is reduced, or the coincidence rate is improved, so as to reduce 3D crosstalk. For example, when the horizontal axis is 0-50, the solid line is multiplied by a value less than 1, and the dashed line is multiplied by a value greater than 1, so as to realize high coincidence of the two lines.

[0036] In the embodiment of the present application, the left spatial distance of each prism column in the 3D prism grating to the left eye of the viewer and the right spatial distance of each prism column to the right eye of the viewer are determined; the left light intensity of the first prism column to the left eye of the viewer is calculated according to the first left spatial distance, and the right light intensity of the first prism column to the right eye of the viewer is calculated according to the first right spatial distance, the first prism column being any prism column of each prism column in the 3D prism grating; the compensation coefficient of the left eye corresponding to the first prism column is calculated according to the left light intensity, and the compensation coefficient of the right eye corresponding to the first prism column is calculated according to the right light intensity; the pixels corresponding to the first prism column are compensated according to the compensation coefficient of the left eye and the compensation coefficient of the right eye, so as to reduce 3D crosstalk.
