Problems solved by technology

[0004] At present, masks can be made by etching Invar sheets and electroforming nickel-iron alloys. Etching Invar sheets requires pre-preparing Invar sheets and then processing them into masks by etching, while electroforming nickel The iron alloy is directly made into a mask by electrodeposition. Relatively speaking, the cost of making a mask by electroforming nickel-iron alloy is relatively low, and the process is simple (electroformed nickel-iron alloy can only be made by electroforming, while etching I

Abstract

The present invention discloses a mask assembly, which comprises a mask plate, an outer frame and auxiliary welding strips, wherein the mask plate is provided with a mask pattern and a semi-etching zone, the auxiliary welding strip is placed in the semi-etching zone, and the mask plate and the auxiliary welding strip are fixed on the outer frame through laser welding. With the mask assembly designed by the present invention, when the materials of the mask plate and the outer frame are different metal materials, the mask plate can be firmly welded on the outer frame through the auxiliary welding strip.

Description

technical field [0001] The invention relates to a mask component, in particular to a mask component for OLED evaporation. Background technique [0002] Organic Light-Emitting Diode (OLED) displays have a series of advantages such as self-illumination, low-voltage DC drive, full curing, wide viewing angle, and rich colors. Compared with liquid crystal displays, OLED displays do not require a backlight source, and the viewing angle Large, low power, its response speed can reach 1000 times that of LCD, but its manufacturing cost is lower than that of LCD with the same resolution. Therefore, OLED displays have broad application prospects and will gradually become the fastest growing new display technology in the next 20 years. [0003] The production of the organic layer material in the OLED structure requires the use of a mask assembly for evaporation. The mask assembly mainly includes a mask plate and an outer frame. The mask plate is usually welded to the outer frame by lase...
