Problems solved by technology

However, due to the characteristics of the material of the sub-pixels in region 1, the lifetime of the blue sub-pixel is the shortest compared to the lifetime of the red sub-pixel and the lifetime of the green sub-pixel
Correspondingly, the brightness of the blue sub-pixel decays faster, which causes problems such as color shift in area 1
[0004] It can be seen that in the prior art, there is a technical problem that the brightness attenuation of each sub-pixel is quite different in the area corresponding to the optical and electronic components in the display area.

Abstract

The present invention provides a display panel and a display device, wherein the display panel includes: a first display area and a second display area; a light emitting unit including a red sub-pixel, a green sub-pixel and a blue sub-pixel; In the first display area, the opening area of ​​the red sub-pixel is A', the opening area of ​​the green sub-pixel is B', and the opening area of ​​the blue sub-pixel is C'; in the second display area, The opening area of ​​the red sub-pixel is A, the opening area of ​​the green sub-pixel is B, and the opening area of ​​the blue sub-pixel is C, where A≤C, B≤C; where A'

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) devices have the advantages of simple structure, fast response, active light emission, low power consumption, etc., and have been widely used in display fields such as mobile phones, tablets, and televisions. [0003] In order to achieve full screen display, such as figure 1 As shown, generally an area 1 that also performs display is set in the display area of ​​the OLED display device, and an optical and electronic component 100 (such as a camera) is set in the area 1 . In the prior art, in order to ensure that the optical electronic element 100 can receive a sufficient amount of light, it is often necessary to increase the transmittance of the region 1 . When the transmittance of area 1 is increased by reducing the pixel density of area 1, it is ...
