technical field

The present invention relates to the technical field of display panels, in particular to a display method applied to a display.

Background technique

Generally speaking, the light transmittance of the liquid crystal display is not the same when the liquid crystal display is viewed from the front and the liquid crystal display is viewed from the side, because the phase retardation (Phase Retardation) generated by the incident light at different angles in the liquid crystal layer is different. According to Gooch-Tarry's Law, the light penetration is related to the refractive index difference and the path length. Because liquid crystals are generally anisotropy and have a birefringence effect, polarized light incident at different angles experiences different refractive index differences in liquid crystals, and the path lengths produced by light entering the liquid crystal layer at different angles are different. , therefore, different brightness will be felt when the viewing angle is different. In addition, the light transmittance is also related to the wavelength. Different colors of light (such as red light, green light, and blue light) have different transmittances when viewed from the front and viewed from the side. The phenomenon of color shift (color shift) in which the displayed colors are not the same. How to reduce the color shift when viewing the liquid crystal display from the front and from the side is one of the topics that the industry is committed to.

Wherein, the weight calculation device first judges whether the indication signal (F) is greater than a first default value (512), if yes, sets the indication signal (F) to the first default value (512), if not, the The indication signal (F) remains unchanged. Then divide the indication signal (F) by the first default value (512) to generate the weighted signal (W). The weighted signal (W) can be expressed by the following formula:

W=F/512.

The low color shift processing device 240 receives the plurality of image data, and performs a color shift processing operation on the plurality of image data to generate a low color shift image signal. The plurality of image data has the first resolution (3840×2160), and a pixel of the plurality of image data includes a red pixel, a green pixel or a blue pixel, that is, the pixel has three colors (red, blue, Green) gray scale, the low color shift processing device 240 calculates an optimal color scale solution corresponding to any gray scale of any color according to the gray scales of the three colors (red, blue, green).

FIG. 2 is a schematic diagram of the optimal color scale solution corresponding to any color gray scale calculated by the low color shift processing device 240 of the present invention. The optimal color scale solution corresponding to any color gray scale calculated by the low color shift processing device 240 includes a first color scale, a second color scale, a third color scale, and a fourth color scale. In other embodiments, the optimal color scale solution corresponding to any color gray scale calculated by the low color shift processing device 240 includes a first color scale and a second color scale.

As shown in Figure 2, wherein the first color level, the second color level, the third color level, and the fourth color level corresponding to the red pixel are arranged according to the upper left, lower left, upper right, and lower right, The first color level, the second color level, the third color level, and the fourth color level corresponding to the green pixel are arranged according to the lower right, upper right, lower left, and upper left, and the corresponding color of the blue pixel The first color level, the second color level, the third color level, and the fourth color level are arranged according to the bottom left, top right, top left, and bottom right.

FIG. 3 is another schematic diagram of the optimal color scale solution corresponding to any color gray scale calculated by the low color shift processing device 240 of the present invention. The low color shift processing device 240 performs 4-pixel low color shift processing (4-Pixel Low Color shift, 4-Pixel LCS). As shown in FIG. 2, the amount of data will increase by 4 times (3840×2160×N, N=4).

In other embodiments, the low color shift processing device 240 can perform 2-pixel low color shift processing (2-Pixel Low Color Shift, 2-Pixel LCS), at this time, the amount of data will increase by 2 times. (3840×2160×N, N=2). 2-pixel low color shift processing is a well-known technology, which will not be repeated here.

The core filtering device 250 is connected to the low color shift processing device 240, and filters the low color shift image signal to generate a filtered image signal, that is, the low color for the bright state and the bright state signal of spatially adjacent pixels, respectively. The partial image signal is filtered, and the dark state and dark state signals are filtered to generate a pixel signal sharing image (Piexl Sharing). In addition to retaining a certain proportion of its own signal, each sub-pixel also has a small proportion of information from the top, bottom, left, and right pixels. Wherein, the core filtering device 250 is represented by the following matrix:

$\left(\begin{array}{ccc}\mathrm{<span\; class="notranslate">\; 0</span>}& \mathrm{<span\; class="notranslate">\; 0.125</span>}& \mathrm{<span\; class="notranslate">\; 0</span>}\\ \mathrm{<span\; class="notranslate">\; 0.125</span>}& \mathrm{<span\; class="notranslate">\; 0.5</span>}& \mathrm{<span\; class="notranslate">\; 0.125</span>}\\ \mathrm{<span\; class="notranslate">\; 0</span>}& \mathrm{<span\; class="notranslate">\; 0.125</span>}& \mathrm{<span\; class="notranslate">\; 0</span>}\end{array}\right)<span\; class="notranslate">\; ,</span>$

It can be known from the matrix that the core filtering device 250 disperses the information of a pixel to the upper, lower, left and right pixels of the pixel, so as to retain part of the information of the pixel in subsequent down-sampling.

The down-sampling (Down-Sampling) device 260 is connected to the core filter device 250 to perform down-sampling on the filtered video signal to generate a down-sampled video signal. In this embodiment, since the low color shift processing device 240 is to perform 4-pixel low color shift processing (4-Pixel Low Colorshift, 4-Pixel LCS), the data is increased by 4 times, so the down-sampling (Down-Sampling) device 260 with 1/2 downsampling in both horizontal and vertical directions. The downsampled resolution returns to 3840×2160.

The weighting device 270 is connected to the temporary storage device 210, the weight calculation device 230, and the downsampling device 260. According to the weighted signal, the weighted operation is performed on the temporary stored image signal and the reduced image signal to output a display signal ( Output). Wherein, the weighting device 270 calculates the display signal according to the following formula:

Output=A×(1-W)+B×W,

Among them, Output is the display signal, A is the reduced image signal that has been processed for low color shift, B is the temporary image signal, and W is the weighted signal. It can be seen from the mathematical formula that when W is 1, it means that the pixel at this location is very likely to be the edge of the at least one object, so Output=B, that is, the original image signal is displayed to prevent the edge of the at least one object from being blurred. When W is 0, it means that the probability that the pixel at this location is the edge of the at least one object is quite low, so Output=A, that is, the image signal after low color shift processing is displayed to reduce the color shift phenomenon. When W is greater than 0 and less than 1, and when W is closer to 1, in the display signal (Output), the original multiple image data is emphasized; when W is closer to 0, in the display signal (Output) , the image signal after low color shift processing is aggravated. Thus, the phenomenon of color shift (color shift) in which the displayed colors of a display are not the same when viewed from the front and viewed from the side can be reduced, and at the same time, the edge of the at least one object is preserved to increase the sharpness. When the display signal is displayed, the two scan lines are turned on at the same time, or the two scan lines are turned on sequentially.
