Description

Technical Field

[0001] The utility model relates to display technology, in particular to a double pixel display panel and a display device. Background Art

[0002] The screen of the display panel is composed of small dots, which are called pixels. The number of horizontal dots and vertical dots of a square display panel is multiplied by the total number of pixels of the screen. However, in order to conveniently express the size of the display panel, it is usually expressed in the form of horizontal pixels × vertical pixels, that is, the resolution of the display panel, such as 1024×768 pixels, which is very common in computer display panels, and 1920×1080 pixels, which is very common in full HD display panels of mobile phones.

[0003] The display panel needs to undergo a display test before leaving the factory to detect whether there are damaged pixels. Since each pixel unit is composed of R pixels, G pixels and B pixels, when a pixel in the pixel unit is damaged, the display panel will have a local color deviation problem and cannot be repaired. If too many pixels are damaged, the display panel can only be scrapped, which undoubtedly increases the product cost. Utility Model Content
