Problems solved by technology

[0003] In the panel technology where the color photoresist is set on the array substrate (Color Filter On Array, COA), there is a more complicated process after the RGB process is completed, and the subsequent process will often affect the RGB organic material, resulting in damage to the OLED device. And then affect the display life and effect

Abstract

The invention discloses a display panel. The display panel comprises a substrate, an active switch and a color photoresist layer, wherein the substrate is covered with a passivation layer; and the passivation layer covers the active switch and the color photoresist layer. By covering the active switch and the color photoresist layer with the passivation layer, occurrence of the gas overflowing problem of the color photoresist layer in subsequent processing of a color filter can be effectively prevented, so that the color photoresist layer can be well protected by the passivation layer, thereby ensuring the service life and efficiency of the display panel without increasing processing steps; and meanwhile, the pattern of a current photomask is not required to be changed, and by only changing the photomask processing sequence, effective protection of the display panel can be realized, so that the display panel achieves a better display effect, thereby further improving the display effect of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. 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] In the panel technology where the color photoresist is set on the array substrate (Color Filter On Array, COA),...
