Abstract

The invention discloses a display panel and a display device, which have a see-through area and a pixel display area. Since at least part of the see-through area has a transparent auxiliary electrode, and the transparent auxiliary electrode is electrically connected to the cathode in the adjacent pixel display area, and the transparent auxiliary The electrodes extend above the cathode auxiliary wiring and are electrically connected to the cathode auxiliary wiring, that is, the cathode is electrically connected to the cathode auxiliary wiring through the transparent auxiliary electrode, so that the resistance of the cathode is reduced by using the transparent auxiliary electrode. Moreover, since the transparent auxiliary electrode is arranged in the see-through area, the area of ​​the pixel display area will not be reduced, and the see-through function of the see-through area will not be affected. In addition, since the transparent auxiliary electrode is arranged in the see-through area with a relatively large area, the area of ​​the transparent auxiliary electrode can also be made larger, thereby greatly reducing the resistance of the transparent auxiliary electrode itself, thereby avoiding the problem of excessive resistance of the transparent auxiliary electrode. The problem of uneven brightness.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is one of the hot spots in the field of flat panel display research today. Compared with liquid crystal displays, OLED has the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. , OLEDs have begun to replace traditional Liquid Crystal Displays (LCDs) in the field of flat panel displays such as mobile phones, PDAs, and digital cameras. [0003] Since the organic light emitting display does not require a separate light source, it is relatively thin and can be used as a see-through display device that is transparent and capable of displaying images. See-through organic light-emitting display devices such as figure 1 as shown, figure 1 It is a schematic structural view of an existing see-through organic ligh...
