Abstract

According to the manufacturing method of the display panel and the display panel, two first through holes, a first open hole and a first opening are formed at the same time through the same photomask, and two second through holes, a second open hole located in the first open hole and a second opening located in the first opening are formed at the same time through the same photomask; the complexity of the manufacturing process of the LTPO display panel can be reduced, the number of photomasks is reduced, and the cost is reduced.

Description

technical field [0001] The present application relates to the field of display, and in particular, to a manufacturing method of a display panel and a display panel. Background technique [0002] Display panels of types such as organic light emitting display (Organic Light Emitting Display, OLED) panels have been widely used in people's lives, such as display screens of mobile phones, computers, and the like. Low temperature polycrystalline oxide (LTPO) display technology combines low temperature polycrystalline silicon (LTPS) and indium gallium zinc oxide (IGZO) two thin film transistors, so it can make the display panel have the characteristics of strong driving ability and low power consumption at the same time. For high-frequency display and low-frequency display, it has increasingly become a hot technology in display panels. [0003] However, the LTPO display panel has the problems that the structure of the display panel is complex, the manufacturing process is complica...
