Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] During the spreading process of the ink droplet, due to the large contact angle between the ink droplet and the substrate of the pixel container, it is very easy to present a spreading shape with a thick middle and a thin edge, which eventually leads to the thickness of the pixel unit formed after drying. Inhomogeneity affects the luminous performance of the device.

Abstract

Embodiments of the present invention refer to a display panel, a display device, and a method for manufacturing a display panel, which solve the problems of uneven thickness of pixel units and poor uniformity of film layers in existing display panels. The display panel includes a substrate and a pixel definition layer disposed on the substrate, the pixel definition layer includes a pixel groove and a balance groove, wherein the pixel groove runs through the first surface of the pixel definition layer and the second surface opposite to the first surface, The balance groove is connected through the pixel groove. The display panel provided by the embodiment of the present invention can effectively ensure the reasonable edge thickness of the pixel unit, prevent the occurrence of the situation that the edge thickness of the pixel unit is too small, and further improve the uniformity of the film layer of the pixel unit, and ensure the luminous performance of the display panel .

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display device and a method for preparing a display panel. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display devices occupy an important position in the field of display technology due to their many advantages such as thinness, high brightness, low power consumption, and high definition. At present, in the preparation process of OLED display devices, pixel units of OLED display devices are usually prepared based on inkjet printing technology. Specifically, an inkjet printing process is used to inject ink material into the pixel containers of the display panel to form ink droplets, and the ink droplets spread in the pixel containers to finally form pixel units. [0003] However, the thickness of the pixel unit in the existing pixel container is not uniform, and the uniformity of the film layer is poor, whic...
