Abstract

The invention discloses a mask plate, and belongs to the technical field of display. The mask plate comprises a frame and a mask support located on the frame, wherein the mask support comprises a plurality of first supporting strips and a plurality of shielding strips which are arranged on the frame, the first supporting strips and the shielding strips are arranged in a staggered manner, and firstgrooves are formed in the sides, facing an evaporation material, of the shielding strips; the mask plate further comprises at least one second supporting strip, each second supporting strip is provided with the corresponding first supporting strip, and the second supporting strips are stacked on the corresponding first supporting strips; and the mask plate further comprises a plurality of mask strips located on the frame provided with the second supporting strips. Due to the structure of the double-layer supporting strips, the supporting effect on the mask strips is improved, and the droopingamount of the mask strips is reduced. The problem that due to the fact that the drooping amount of the mask strips is large, the mask strips and a substrate are poor in attaching is solved, and the effects of reducing the drooping amount of the mask strips and improving the attaching tightness of the mask strips and the substrate are achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a mask. Background technique [0002] At present, when making the light-emitting layer of the display panel, the electroluminescent material is first sublimated by evaporation, and then deposited on the substrate attached to the mask after passing through the mask, and then forms an evaporation pattern to achieve Glowing purpose. Therefore, the performance of the mask is directly related to the quality of the OLED display panel. [0003] A mask plate, including a frame, a mask bar and a mask bracket arranged on the frame, the mask bracket includes a plurality of support bars and shielding bars, and the mask bar is supported by the support bars to avoid the sagging of the mask bar is too big. [0004] In the above method, the supporting force of the support strips for the mask strips may be insufficient, resulting in a large amount of sagging of the mask strips, whic...
