Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] An embodiment of the mask assembly for preventing glass substrates from being scratched is as Figure 1 to Figure 2 As shown, the mask plate assembly for preventing scratching of the glass substrate in this embodiment includes a mask plate 1 and a frame 2 welded on the periphery of the mask plate 1, and the mask plate 1 includes a mask version body 11 and is fixedly connected to the The welding area 12 on the periphery of the mask version body 11, the upper surface of the welding area 12 is lower than the upper surface of the mask version body 11, the outer peripheral surface of the welding area 12 is welded together with the inner peripheral surface of the frame 2, and the upper surface of the welding area 12 The height difference from the mask version body 11 is greater than the height of the solder joints. The upper surface of the ...

The invention discloses a mask assembly capable of preventing a glass base plate from being scratched, and belongs to the technical field of OLEDs. The mask plate assembly capable of preventing the glass base plate from being scratched comprises a mask plate and a frame welded to the periphery of the mask plate, the mask plate comprises a mask plate body and a welding area fixedly connected to theperiphery of the mask plate body, the upper surface of the welding area is lower than the upper surface of the mask plate body, and the outer circumferential face of the welding area and the inner circumferential face of the frame are welded together. According to the mask plate assembly capable of preventing the glass base plate from being scratched, the welding area is arranged on the peripheryof the mask plate body, due to the fact that the upper surface of the welding area is lower than the upper surface of the mask plate body, the welding area is of a concave structure on the whole maskplate, and when the periphery of the concave welding area is welded to an inner shaft of the frame, generated welding spots are located on the upper surface of the welding area and lower than the upper surface of the mask plate body, so that the welding spots do not protrude out of the upper surface of the mask plate body, the glass base plate in the subsequent evaporation process is further prevented from being scratched, and scratches are avoided.
Description
technical field [0001] The invention relates to a mask assembly for preventing glass substrates from being scratched, and belongs to the technical field of OLEDs. Background technique [0002] The mask plate assembly includes a mask plate and a frame fixed on the outer periphery of the mask plate. In the prior art, the frame is usually welded on the periphery of the mask plate to form a mask plate assembly. However, when the mask plate is welded to the frame , solder joints will be generated, and the solder joints protrude on the upper surface of the mask plate and the frame. Since a glass substrate needs to be placed on the upper surface of the mask plate assembly during the subsequent evaporation process, the protruding solder joints on the mask plate assembly Dots will scratch the glass, causing scratches on the glass substrate. Therefore, there is a need for a mask assembly capable of preventing glass substrates from being scratched. Contents of the invention [0003...
