Abstract

A display panel comprises a substrate, pixel definition layers and a plurality of sub-pixels, the pixel definition layers define a plurality of sub-pixel areas, the sub-pixels are arranged in the sub-pixel areas in a one-to-one correspondence mode, the sub-pixels comprise main pixels and sub-pixels surrounding the main pixels, and the main pixels and the sub-pixels are independently driven by different driving circuits respectively. The sub-pixels are designed into the main pixels and the sub-pixels surrounding the main pixels, and the main pixels and the sub-pixels are independently driven respectively, so that the brightness of the sub-pixels is favorably adjusted, and the light-emitting service life of the sub-pixels is favorably compensated; besides, by arranging the three pixel definition layers and controlling the heights and the material types of the three pixel definition layers, the printing difficulty of the light-emitting material can be reduced, and therefore mass production of products can be achieved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a manufacturing method thereof. Background technique [0002] Organic electroluminescent display (Organic Light Emitting Display, OLED) is a new generation of display, OLED device usually includes a cathode, an anode, an organic thin film sandwiched between the cathode and the anode, after a voltage is applied between the cathode and the anode, the Organic thin films emit light. Compared with liquid crystal displays, OLED displays have many advantages such as self-illumination, fast response, wide viewing angle, and color saturation. [0003] Printed organic electroluminescence display (OLED) is a display technology that combines modern printing process with OLED display. It has the advantages of simple process, high material utilization, low cost, environmental protection, flexibility, etc. mainstream technology. Since the lifespan of the l...
