Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. . Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0030] OLED display devices are more and more widely used, and mask components are usually used to manufacture OLED display devices. For example, please refer to figure 1 , the mask assembly 10 may include: a mask plate 101, a mask frame 102, and a fine metal mask ( figure 1 not shown in ), where the edge of the mask plate 101 is welded to the mask frame 102 . During the welding process, stress F1 will be generated on the welded part of th...

Abstract

The invention provides a mask, and belongs to the technical field of display. The mask comprises a mask main body, wherein a hollow region is arranged on the mask main body, n bulges are arranged at an edge of the mask main body in an upward extension way, and n is more than or equal to 3. By the mask, the problem that the mask can be deformed under an effect of stress generated by welding duringthe welding process of the mask and a mask frame to further cause that the hollow region in the mask also can be deformed is solved. The mask is used for manufacturing a mask assembly.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask plate and a mask component. Background technique [0002] Organic Light-Emitting Diode (English: Organic Light-Emitting Diode, referred to as: OLED) display devices are more and more widely used due to their many advantages such as active light emission and fast response speed, and OLED display devices are usually manufactured using mask components. [0003] For example, the mask assembly generally includes: a mask frame, a mask plate and a fine metal mask. Wherein, the edge of the mask plate is welded to the mask frame, the mask plate is provided with a hollow area, the fine metal mask covers the hollow area, and a hollow pattern is formed on the fine metal mask. Please refer to figure 1 , when making the mask assembly, it is necessary to weld the edge of the mask plate 101 to the mask frame 102 . During the welding process, stress F1 will be generated on the welded p...
