Embodiment Construction

[0050] As mentioned in the background art, the display panel in the related art has the problem of pixel crosstalk. The inventors have found through research that the reason for this problem is that when a certain pixel unit among the plurality of pixel units is lit, due to the application of The high turn-on voltage of this pixel unit will cause other pixel units turned on with low voltage to be turned on, thus causing crosstalk between pixels.

[0051] The inventor further found that the reason for the leakage current between the pixel unit and other adjacent pixel units is that the first common layer of each pixel unit usually adopts a large-opening common mask (Common Mask) or an open mask (Open Mask) making, so that the first common layer of each pixel unit has an integrated structure. When a voltage is applied to a certain pixel unit, carriers (usually holes) in the first common layer migrate laterally, thereby causing a leakage current between the pixel unit and other a...

Abstract

The invention provides a display panel and a display device, relates to the technical field of display. The display panel is used for solving the technical problem of pixel crosstalk of the display panel. The display panel comprises an array substrate; a pixel limiting layer, arranged on the array substrate and comprising a plurality of pixel openings; the light-emitting units comprise a first color light-emitting unit, a second color light-emitting unit and a third color light-emitting unit which are respectively arranged corresponding to the pixel openings; at least one groove is formed in the peripheral side of the pixel opening corresponding to the first color light-emitting unit; the first common layer is located on the side, away from the array substrate, of the pixel limiting layer, and the first common layer located in the groove and on the peripheral side of the groove is a continuous film layer. The grooves are formed, and the first common layer is the continuous film layer, so that a carrier transverse transmission path between the light-emitting units of the first light-emitting color and the light-emitting units of other colors is increased, the transverse transmission capacity of carriers in the first common layer is reduced, and pixel crosstalk of the display panel is improved or avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) has many characteristics such as self-illumination, fast response, wide viewing angle and can be fabricated on flexible substrates. It is increasingly used in high-performance display fields such as flexible display devices. middle. [0003] A display panel generally includes a plurality of pixel units, such as a red pixel unit, a blue pixel unit and a green pixel unit. When a certain pixel unit in the display panel is turned on, other pixel units near the pixel unit are also likely to be turned on at the same time, resulting in pixel crosstalk. Contents of the invention [0004] In view of the above problems, embodiments of the present application provide a display panel and a display device for reducing pixel crosstalk of the display panel. [0005] In order t...
