Detailed ways

In order to facilitate the understanding of the application of the present invention, a more comprehensive description of the application of the present invention will be given below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the application of the present invention can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

Figure 1 shows a schematic structural diagram of a related true pixel arrangement structure. The rectangular structures located inside in FIG. 1 are sub-pixel R, sub-pixel G, and sub-pixel B. For the convenience of description, the sides of the sub-pixel rectangular structure are called sub-pixel sides.
