Background technique

In a conventional display device, a pixel is formed by sub-pixels of three colors of red, green and blue (RGB) or sub-pixels of four colors of red, green, blue and white (RGBW) as shown in FIG. 1 . In practical applications, the resolution of the display device can be improved by increasing the number of pixels per inch (PixelsPerInch, PPI for short) of the display device. However, in order to improve the PPI, it is necessary to reduce the pixel size and the distance between pixels as much as possible. However, with the continuous refinement of the process, the improvement of the process will reach the limit.

In the prior art, three sub-pixels or four sub-pixels form one pixel. When a display device requires a large number of pixels to achieve high-resolution display, the required number of sub-pixels is also large. Therefore, there are following technical problems:

1) In the prior art, the actual display resolution of the display device is the same as the physical resolution of the display device. If a higher display resolution is desired, it is necessary to increase the physical resolution of the display device by increasing the number of sub-pixels. Since there is also a limit to the improvement of the process, it is difficult to increase the number of sub-pixels when it reaches a certain number;

2) The number of sub-pixels in the display device is large, resulting in a large number of data lines, thereby increasing the power consumption of the display device and reducing the aperture ratio of the display device;

3) The number of sub-pixels in the display device is large, and the size of each sub-pixel is small, which makes the manufacturing process of the display device difficult and expensive.
