Abstract

The invention provides a display panel and a display device. The display panel includes a substrate; a plurality of pixels including a first pixel and a second pixel; and a display area which comprises a first sub-display area and a second sub-display area, wherein the first pixel is located in the first sub-display area, the second pixel is located in the second sub-display area, and the pixel density of the first sub-display area is less than that of the second sub-display area; the first pixel comprises a first pixel defining wall, and at least two adjacent first pixel defining walls are independent of each other. In the invention, the first pixel defining wall blocks a part of incident light. The light transmittance of the area where one first pixel defining wall is located is smaller than that of the area between every two adjacent first pixel defining walls. An area between two adjacent first pixel defining walls is high in light transmittance. In this way, the overall light transmittance of the first sub-display area is further improved, and optical components such as a camera arranged below the first sub-display area can receive sufficient optical signals.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] In display technology, Organic Light Emitting Diode (OLED) is widely used in the industry due to its thinness, active light emission, fast response speed, wide viewing angle, rich colors and high brightness, low power consumption, and high and low temperature resistance. It is recognized as the third-generation display technology after Liquid Crystal Display (LCD). [0003] figure 1 It is a structural schematic diagram of a display device in the prior art. [0004] Such as figure 1 As shown, in the prior art, a display device 100 includes a display panel 110 and an optical component 120 . The display panel 110 covers the optical part 120 . The display panel 110 includes a pixel definition layer 111 and an organic light emitting layer 112 . Wherein, the pixel definition layer 111 is provided wit...
