In the production industry of display panels, the production work is divided into clear and complete systems, and the defects of the display panels are also exposed in the mature and traditional production mode.
Because the pixel structures and the pixel drive are independently produced and then packaged, when a plurality of pixel structures are packaged on the panel substrate, enough area mounting pixel drive needs to be reserved, as shown in fig. 3, the general pixel structures 10 are arranged in an array distribution mode, and the pixel drive is mounted in the reserved area between two adjacent columns of pixel structures, so that the transition gap 20 between two adjacent columns of pixel structures is large, the display panel is caused to have jumping and trailing problems when the display elements are translated in the display process, and because each part is independently produced, the problem is difficult to solve by controlling the distance between the pixel structures in the panel substrate factory when packaging. Furthermore, in the existing display panel, the arrangement modes of the RGB sub-pixels are consistent among a plurality of pixel structures, so that the interactivity between the sub-pixels of the pixel structures is poor, only a single pixel structure can be used as a pixel point for displaying, and when the display elements are translated, the distance between the pixel point and the pixel point is large, and the problems of display jumping and smear are also highlighted.
Accordingly, the prior art is in need of improvement and development.
