Mask assembly assembling method

Abstract

The invention discloses a mask assembly assembling method. The mask assembly assembling method comprises steps of external force application, tension application, alignment installation and external force release. The mask assembly assembling method is characterized in that through one or more tension application steps, alignment installation steps and external force release steps, one or more mask units are installed to a mask frame; and after all the mask units are installed, all external forces are released so that a mask assembly is obtained. Through the mask assembly assembling method, the shape of the mask frame provided with all the mask units is basically the same as that of the mask frame without the mask units, in other words, the shape of the mask frame is basically unchanged and thus a mask assembly precision is improved so that a precision and quality of the product are improved.

Description

technical field [0001] The invention relates to the field of OLED manufacturing, in particular to a method for assembling a mask component. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have self-illumination at the same time, no backlight is required, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, and have a wide temperature range It is considered to be the next-generation flat-panel display emerging application technology due to its excellent characteristics such as simple structure and manufacturing process. [0003] Mask components for evaporation are needed to make the organic layer of OLED display, such as figure 1 As shown, it is a schematic diagram of the overall planar structure of the mask assembly. The mask assembly includes a mask frame 11 and a mask plate 10. The mask plate 10 is provided with mask pattern areas 101 and 12 formed by evaporation holes. T...

[0003] Mask components for evaporation are needed to make the organic layer of OLED display, such as figure 1 As shown, it is a schematic diagram of the overall planar structure of the mask assembly. The mask assembly includes a mask frame 11 and a mask plate 10. The mask plate 10 is provided with mask pattern areas 101 and 12 formed by evaporation holes. The mask plate is fixed on the solder joint on the mask frame. Usually, the mask plate is fixed on the mask frame 11 by laser welding after applying a certain tension, and the tension of the mask plate 10 is converted into a pulling force on the mask frame 11. The mold frame is deformed under the tension of the mask plate, which affects the position accuracy of the evaporation holes in the mask pattern area. The position accuracy is not high and the quality of the OLED display is not high.
