Display panel and display device

Abstract

The invention describes a display panel and a display device. The display panel comprises a pixel group. The pixel group comprises a first sub-pixel pair and a second sub-pixel pair. The first sub-pixel pair and the second sub-pixel pair respectively comprise two sub-pixels of the same color, and the two sub-pixels of the same color are adjacent and arranged along a first direction. At least one third sub-pixel is located at the central position between the first sub-pixel pair and the second sub-pixel pair. The pixel group comprises a first pixel group and a second pixel group. The first pixel group and the second pixel group are axially symmetrical, and the axis of symmetry extends along the first direction. The first pixel group is arranged in a first pixel column along the first direction, the second pixel group is arranged in a second pixel column along the first direction, and the first pixel column and the second pixel column are alternately arranged along a second direction. The adjacent sub-pixels of the same color are assembled together as much as possible so that smaller pixel size and high PPI can be realized. Besides, the sub-pixels of the same color form a straight line so as to be beneficial to manufacturing of the sub-pixels and improve the process efficiency.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] In recent years, with the continuous development of display technology, various display devices have emerged, such as liquid crystal display devices, organic light-emitting display devices, etc., which have become mainstream products in the display industry. Among them, organic light-emitting display panels are thinner, lower A series of excellent performances such as power consumption, high brightness, high contrast, high resolution, and wide viewing angle have become the mainstream trend in the development of the display industry, and are currently a hot research topic in the display field. [0003] The current development trend of display screens for mobile phones and tablet PCs is high resolution and high display quality. Therefore, designing high PPI (pixel per inch) OLED displays is a very critical technology fo...

Problems solved by technology

[0004] For the evaporation process, the openings of the evaporation mask (MASK) correspond to the sub-pixels one by one, and the red, green and blue blocks correspond to the sub-pixels one-to-one. When the design resolution is high enough, the evaporation mask will not be able to Corresponding (color mixing defects occur), which limits the improvement of product resolution

[0005] For the printing process: Due to the limitation of the droplet size and precision that can be printed at present, it is difficult to further improve the PPI of the display by using the traditional red, green and blue strip pixel design (RGB Strip)
