Problems solved by technology

[0004] The present application provides a display panel, a method for preparing a display panel, and a display device. On the one hand, it solves the problem of color mixing in the blue sub-pixel area caused by abnormal evaporation of red luminescent material and / or green luminescent material to the blue sub-pixel area. The problem, on the other hand, has improved to a certain extent the problem of color shift in OLED display panels caused by blue light attenuation

Abstract

The invention provides a display panel, a display panel preparation method and a display device. According to the display panel, a blue light compensation pattern is additionally arranged around a blue sub-pixel region; the blue light compensation pattern has the characteristics of absorbing light with the wavelength larger than the wavelength of blue light and converting the light into blue light, so that the problem of color cast of the OLED display panel due to blue light attenuation is solved, and meanwhile, the problem of color mixing due to abnormal coating to a blue sub-pixel area is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel, a method for preparing a display panel, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display technology has been developed for more than 30 years, and is currently widely used in lighting, display and other fields. The OLED display panel has the advantages of high brightness, high contrast, low power consumption, fast response speed, wide viewing angle, etc. In addition, because the OLED display panel has the characteristics of self-illumination, no additional backlight is needed, so the OLED display panel has a thin thickness and light weight. The characteristics are in line with the development trend of thinner and lighter displays. [0003] At present, in the manufacturing process of the OLED display panel, a fine metal mask (FMM) is used to vapor-deposit a small molecule organic light-emitting materia...
