Display panel and display device

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a first display area and a second display area, the second display area is multiplexed as alight sensing element setting area, the first display area comprises a plurality of first pixels arranged in an array, and the second display area comprises a plurality of second pixels arranged in anarray; each first pixel comprises a plurality of first sub-pixels, each second pixel comprises a first area and a second area, each first area comprises a plurality of second sub-pixels, the area ofthe first sub-pixels is smaller than that of the second sub-pixels, and the area of the first area is smaller than or equal to that of the second area; the second area is in an open state when a lightsensing element works, and external light enters the light sensing element through the second area; and the second area is in a closed state when the display panel performs full-screen display, and the second sub-pixels are used for realizing normal display of the second display area. According to the technical scheme of the embodiment of the invention, normal display of the under-screen light sensing element setting area can be realized, and the screen-to-body ratio of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] At present, the demand for high screen-to-body ratio for mobile phones and other products is increasing day by day, and the market penetration rate of full screen is close to 70%. The so-called screen-to-body ratio is the ratio of the screen area to the overall machine area. A higher screen-to-body ratio can bring users a better visual experience. [0003] Since the camera, light sensor and other components need to be placed on the front of the mobile phone, there are usually two existing solutions. One is to design a non-display area at the top of the screen, such as the "notch screen", "water drop screen", etc. Solutions such as "hole-digging screen" cannot display images in non-display areas; the other is a lifting camera. Although it can realize full-screen display, it requires the response ...

[0003] Since the camera, light sensor and other components need to be placed on the front of the mobile phone, there are usually two existing solutions. One is to design a non-display area at the top of the screen, such as the "notch screen", "water drop screen", etc. Solutions such as "hole-digging screen" cannot display images in non-display areas; the other is a lifting camera. Although it can realize full-screen display, it requires the response time of the camera mechanism when shooting, and the camera has no casing protection, and the lifting structure will increase. The thickness of the mobile phone is not conducive to the development of light and thin
