Problems solved by technology

This traditional process has a large number of channels and the process is complex, but if the pixel definition layer is omitted, it will cause uneven display or color mixing of the self-luminous panel, which will affect the display effect

Abstract

The invention discloses a display panel and a method of manufacturing the same. The manufacturing method comprises: providing a substrate; forming an active switch on the substrate; forming a light emitting layer electrically connecting to the active switch on the active switch; and forming a passivation layer having a recessed part between the active switch and the light emitting layer; and filling a color photoresist layer aligned to the light emitting layer in the recessed part of the passivation layer. With the recessed part of the passivation layer, the color photoresist layer can be formed in the recessed part directly in a filing manner.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, relates to an organic light emitting diode display panel and a manufacturing method thereof. Background technique [0002] Active-matrix organic light emitting diode (AMOLED) display screens have the characteristics of high contrast, wide color gamut, and fast response speed. Since AMOLED is self-illuminating and does not require a backlight, it can be made thinner and even more flexible than AMLCD. The AMOLED display is mainly controlled by a specific TFT to adjust the switch and brightness of the OLED device, and the screen is displayed after adjusting the ratio of the three primary colors. Among them, the control TFT often uses a metal oxide semiconductor, which not only has a high on-state current and a low off-state current, but also has the characteristics of high uniformity and stability. [0003] After the anode process, pixels are defined with a pixel de...
