Abstract

The invention relates to a display panel, a preparation method thereof and a display device, and solves the problem that pixel units in a present display panel is uneven in thickness and low in film homogeneity. The display panel comprises a pixel limiting layer and a conducting layer laminated with the pixel limiting layer, and the first surface, adjacent to the pixel limiting layer, of the conducting layer is provided with infiltration patterns. Thus, the spreading speed of ink drops is improved, the concentration difference of the ink drops is reduced, and finally, the film homogeneity of the pixel unit is improved, and light emitting performance of the display device is ensured.

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 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 dro...
