Abstract

The invention discloses an evaporation masking plate. The evaporation masking plate is used for evaporating a pixel region on a display panel. The display panel comprises a substrate, a pixel limiting layer arranged on the substrate, and cushion blocks arranged on the pixel limiting layer. The substrate is divided by the pixel limiting layer into a plurality of sub-pixel regions, and the sub-pixel regions include the evaporation sub-pixel regions and the non-evaporation sub-pixel regions. The evaporation masking plate comprises a masking plate body and evaporating holes formed in the masking plate body, and the evaporating holes penetrate the masking plate body. A thinning region is arranged at the portion, corresponding to the cushion blocks on the display panel, of the masking plate body so that the thickness of the position, corresponding to the cushion blocks on the display panel, of the masking plate body can be smaller than the whole thickness of the masking plate body. By means of the evaporation masking plate, a gap between the evaporation masking plate and the substrate can be removed, the attachment compact degree can be increased, the color mixing risk can be reduced, and the evaporation quality can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an evaporation mask and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diodes (OLED for short) are self-luminous devices that do not require a backlight source and are light and thin in appearance, while traditional liquid crystal displays (LCDs) require a backlight source to work and have a thicker appearance. Organic light-emitting diode displays have low power consumption, wide viewing angles, and fast screen response, which is the technology that best meets people's future functional requirements for displays. Therefore, organic light-emitting diodes are expected to replace liquid crystal displays in the near future and have high market potential. [0003] In the production process of organic small molecule light-emitting diodes, the current relatively mature technology is the use of vacuum evaporation technology. During the device prep...
