Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises a plurality of pixel units as well as a light-sensitive unit and a processing chip, wherein the plurality of pixel units are distributed in a matrix manner; at least part of the pixel units comprise light emitting areas and light transmittance areas; the processing chip is connected with the output end of the light-sensitive unit; after the intensity of ambient light is sensed by the light-sensitive unit, a corresponding current signal is generated and transmitted to the processing chip; a gray scale value of a light transmittance area corresponding to the light-sensitive unit is judged by the processing chip according to the received current signal, and a control signal for controlling the gray scale of the light transmittance area to be displayed as the gray scale value is output to the light transmittance area. Due to arrangement of the light-sensitive unit and the processing chip in the display panel disclosed by the embodiment of the invention, the light transmittance rates of the light transmittance areas can be adjusted under the action of the light-sensitive unit and the processing chip, furthermore, the influence of relatively intense ambient light to a display screen can be reduced, the screen contrast ratio can be ensured, and thus the screen quality of the display panel can be improved.

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] At present, with the continuous development of display technology, displays have been widely used in various electronic devices, and the diversification of displays has gradually become one of the important features of electronic devices. Among them, the transparent display panel is a new type of display screen, such as Figure 1a As shown, the transparent display panel has both a light-emitting area (that is, a display area) that can realize a normal display function and a light-transmitting area that allows ambient light to pass through. Usually in the design, the light-transmitting area is coated with white color resist or transparent color resist or even not coated with resin, so that the ambient light can pass through and the background can be seen clearly. Figure 1b It shows a pixel arrangement for trans...

Problems solved by technology

When displaying images, when the ambient light is dark, less light is transmitted, which has little effect on the display screen, and the display screen can be seen more clearly; when the ambient light is strong, more light is transmitted, Both the light emitted by the light-emitting area and the natural light passing through the light-transmitting area will enter the user's eyes. From the perspective of the human eye, the contrast of the image displayed on the transparent display panel will decrease, so that people can't see the display screen clearly and think that the display quality is low.
