Problems solved by technology

[0003] Mask components for evaporation are needed to make organic layers of OLED displays, 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 mask frame by laser welding to form solder joints. 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 to the mask frame 11. The tension of the mask frame is deformed under the tension of the mask plate, and the mask plate sags due to its own gravity during the evaporation process, which affects the position accuracy of the evaporation holes in the mask pattern area, and the position accuracy is not high. The quality of the OLED display is not high

Embodiment Construction

[0062] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0063] The inventive idea of ​​the present invention is as follows, because in the prior art, in the process of assembling the mask assembly, when the mask plate with a certain tension is installed behind the mask frame, the tension of the mask plate is converted into a pulling force on the mask frame , The mask frame is deformed under the action of tension, which will have a great impact on the accuracy and quality of the product, and at the same time reduce the yield. A method for assembling a mask assembly provided by the present inve...

Abstract

The invention discloses an assembling method of a mask assembly. The method includes the steps of installation of shielding strips and installation of mask units. The shielding strips shield the gaps between adjacent mask units, and the strips mask do not shield the mask patterns on the mask units. According to the assembling method of mask assembly provided by the invention, in the step of installation of mask units, the fixed edges of the mask frame are first applied with predetermined external force, part of the external force is withdrawn every time a mask unit is installed, and the external force is completely withdrawn when all the mask units are installed, such that the mask frame maintains a basically same shape before the installation of the first mask unit and after installation of all the masks. The shielding strips also have supporting effect on the mask units to prevent sagging of the mask units due to own gravity, so as to improve the accuracy of the mask assembly and further improve the precision and quality of the product.

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] Because Organic Light-Emitting Diode (OLED) has self-illumination at the same time, no backlight is needed, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide temperature range, The excellent characteristics such as simple structure and manufacturing process are considered to be the emerging application technology of the next generation of flat-panel displays. [0003] Mask components for evaporation are needed to make organic layers of OLED displays, 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 mask f...
