In the column direction, the same color The sub-pixels are not adjacent, and the sub-pixels of odd-numbered rows and even-numbered rows are not aligned, that is to say, different rows in the display panel of the BV3 pixel structure are not aligned, that is, the starting positions of adjacent rows are "staggered" by half a sub-pixel. Therefore, in the column direction, each sub-pixel (a small number of sub-pixels except the edge) is adjacent to two sub-pixels in an adjacent row at the same time, and is located in the middle of these two sub-pixels, at this time, three sub-pixels of different colors are It crosses between them in a shape similar to that of a "pin-shaped".

The image information currently input to the display panel of the BV3 pixel structure is the image information of the Real RGB pixel structure. The Real RGB pixel structure is shown in Figure 2, including several R sub-pixels, G sub-pixels and B sub-pixels arranged in an array. In the column direction, the sub-pixels of the same color are adjacent, and the sub-pixels of the odd-numbered and even-numbered rows are aligned; and the size of the two second pixels 21 composed of adjacent six sub-pixels in the Real RGB pixel structure is the same as that of the BV3 pixel. In the structure, a first pixel 11 composed of three adjacent sub-pixels has the same size.

Since the image information input into the display panel of the BV3 pixel structure is the image information of the Real RGB pixel structure, it is necessary to use an image rendering method to render the image information corresponding to the Real RGB pixel structure into the image information corresponding to the BV3 pixel structure.
