Document Type and Number:
WIPO Patent Application WO/2021/190123
Kind Code:
A1
Abstract:
Provided are a mask (20), a display panel, and a method for preparing the mask (20). The mask (20) comprises a fully light-transmitting area (210), a semi-light-transmitting area (220) and a non-light-transmitting area (230), wherein the fully light-transmitting area (210) is used for forming a pixel opening (100) of a display panel; the semi-light-transmitting area (220) is used for forming a pixel defining layer (200) of the display panel; and the non-light-transmitting area (230) is used for forming a supporting column (300) for the display panel. By using the mask (20), three structures, i.e. a pixel opening (100) area, the pixel defining layer (200) and the supporting column (300), can be simultaneously formed with only one masking process; and compared with the prior art, the number of masking processes required in a preparation process for an OLED display panel is reduced, and the process flow is simplified.
