Abstract

The embodiments of the present invention refer to a film structure, a display panel, a display device, and a film structure preparation method, which solve the problems of uneven thickness of pixel units and poor film uniformity in the existing film structure. The film layer structure includes a pixel defining layer and a conductive layer laminated with the pixel defining layer, the first surface of the conductive layer includes a raised portion, wherein the first surface is a surface adjacent to the pixel defining layer. The film layer structure provided by the embodiment of the present invention realizes uniform thickness and good film layer uniformity based on the surface tension of the ink droplet by providing a raised portion on the first surface adjacent to the conductive layer and the pixel defining layer. The purpose of the pixel unit, thereby improving the uniformity of the film layer of the pixel unit, and ensuring the light-emitting performance of the film layer structure.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a film layer structure, a display panel, a display device and a method for preparing the film layer structure. Background technique [0002] OLED (Organic Light-Emitting Diode) display device occupies an important position in the field of display technology due to its advantages of 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 container to form ink droplets, and the ink droplets spread in the pixel container to finally form pixel units. [0003] However, during the spreading process of the ink droplet, the solvent volatilization rate is different between the edge area and the central area of ​​the ink droplet, whi...
