The method of the embodiment of the present invention is described in detail below by using application examples, which are only used for illustrating the present invention and are not used for limiting the protection scope of the present invention.
Application example
The application example of the invention can be used for the problem of color cast of the transparent area caused by common sub-pixel (Pentia) pixel arrangement, the under-screen camera technology and the IC SPR algorithm patch in the full-screen display technology. The application example of the invention realizes color cast processing, and can process color cast of local transparent display of pure color images, gray-scale images and natural images.
In the related art, when the gray scale values are set before the transparent area image is displayed, the gray scale values are often set to be the same; for example, the gray scale values are all set to be 255, and if the panel loads the parameter, the displayed image is all white; the application example of the invention adjusts the gray scale value of the transparent area before the transparent area displays the image, and the corresponding distribution after the gray scale value of the transparent area is adjusted is lattice distribution; the application example of the present invention performs gray scale processing on the local pixel illustrated in fig. 2-1, fig. 7 is a schematic diagram of the local pixel distribution after performing gray scale value processing according to the application example of the present invention, it should be noted that the pixel distribution illustrated in fig. 7 is not a real pixel distribution, but is a schematic diagram abstracted by setting a gray scale value, and for fig. 7, the application example of the present invention performs the following processing: performing gray-scale value zeroing processing on a first non-pixel position sharing a sub-pixel with a pixel position and a second non-pixel position in diagonal relation with the first non-pixel position; fig. 8 is a diagram illustrating a distribution of pixels for gray-scale processing according to an exemplary application of the present invention, and refers to an image position corresponding to a transparent area of a Panel (Panel) at a lattice position of fig. 8. The application example of the invention is that the common design of the non-color-shift lattice arrangement is displayed according to Panel pixel arrangement, local transparent area pixel arrangement design and Panel IC SPR, namely, on the basis that the local transparent area has pixel position setting points, the lattices with different regular arrangements are designed at the non-pixel positions (except the pixel positions corresponding to the SPR rendering common sub-pixels) of the transparent area, so that the lattices which normally display the non-color shift can be used as the pixels of the images corresponding to the transparent area, and the non-color-shift images are displayed in the Panel transparent area.
The application example of the invention can integrate the algorithm for correcting the color cast of the transparent area based on Panel IC SPR into an IC, so that the original image data is subjected to color cast correction through the algorithm for correcting the color cast of the transparent area integrated in the IC, namely, the transparent area is processed according to a non-color cast lattice designed based on the Panel IC through the algorithm for correcting the color cast of the transparent area, so that the image block of the transparent area is processed into a lattice conforming to the design; because the pixel density of the transparent area is smaller, when the same image is displayed, the brightness of the transparent area is darker than that of the normal area, the application example of the invention improves the brightness of the transparent area by improving the gray scale of the transparent area, and simultaneously performs gray scale infiltration on the boundary of the transparent area and the normal area to weaken the boundary dividing line between the transparent area and the normal area; using fewer sub-pixels to achieve a higher number of Pixels Per Inch (PPI) through an image sub-pixel sharing algorithm; the uneven color blocks appearing in Panel are weakened, the application example of the invention realizes color cast processing, and better visual effect images can be obtained; fig. 9 is a flowchart of a method of an application example of the present invention, as shown in fig. 9, including: color shift correction by an algorithm for correcting color shift of the transparent region integrated in an Integrated Circuit (IC); improving the gray scale of the transparent area to improve the brightness of the transparent area, and performing gray scale infiltration on the boundary of the transparent area and the normal area; performing an image sub-pixel sharing algorithm process to achieve a higher number of Pixels Per Inch (PPI) with fewer sub-pixels; the non-uniform patches in the panel are subjected to a de-emphasis process.
The invention discloses an application example of RGBG Pentile pixel arrangement and an example of local transparent area 4 bright 1, wherein pixels corresponding to pixel positions in a transparent area are reserved, pixels corresponding to pixel positions in a transparent area are reserved or set to be 0 according to a certain rule (pixels corresponding to the positions of sub-pixels shared by the pixels in the pixel positions in the transparent area need to have a gray level value set to be 0, the phenomenon that an image in the transparent area is greenish, the reason of greenish is related to ICSPR sub-pixel sharing) is prevented), the dot matrix which is designed according to the method and can enable a Panel IC to display the colorlessness is a transparent area display colorlessness image designed based on a Panel IC SPR, the pixels in the transparent area are correspondingly processed according to the colorlessness dot matrix rule, the positions of bright spots are reserved with original image gray levels, and the positions of black spots correspond to image pixel gray levels set to be 0. For different Panel ICs, the image corresponding to the transparent area can be processed into a dot matrix without color cast by the method, so that the color cast displayed by the transparent area can be corrected.
