Abstract

The invention relates to a display panel, a multi-area display panel and a display device. The display panel comprises a light emitting device layer, wherein the light-emitting device layer comprisesa plurality of sub-pixels, and each sub-pixel comprises a first electrode, a light-emitting layer and a second electrode which are stacked in sequence; and an electrochromic device which is used in cooperation with the first electrode or shares a control electrode with the first electrode, wherein the control electrode is used for controlling voltage applied to the two ends of the electrochromic device to switch the light transmittance of the display panel. The electrochromic device and the first electrode are combined or share the control electrode, the electrochromic device is set to be in alight-proof state when the sub-pixels emit light and is used for weakening reflection of external light and improving the display effect, and the electrochromic device is set to be in a light-transmitting state when the sub-pixels do not emit light and is used for allowing the external light to pass through so that the photosensitive device arranged below the display panel can receive the external light, and the photographing function is achieved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display panel, a multi-region display panel and a display device. Background technique [0002] With the rapid development of display devices, users have higher and higher requirements for screen-to-body ratio. Since cameras, sensors, earpieces and other components need to be installed above the screen, a part of the area above the screen is usually reserved in the prior art for the installation of the above-mentioned Components, such as the front notch area of ​​the iPhone X, affect the overall consistency of the screen, and the full-screen display has attracted more and more attention from the industry. Contents of the invention [0003] The object of the present invention is to provide a display panel for a full screen, a multi-region display panel and a display device. [0004] In order to achieve the above object, the first aspect of the present inventio...
