Problems solved by technology

[0003] In the prior art, when a preset force is applied to the mask frame, in order to reduce friction, the mask frame is usually placed on the air bearing, and the mask frame is supported by the air bearing. However, the existing mask There is a problem that the plate frame cannot be supported by air floatation, which affects the accuracy of the subsequent application of preset force to the mask frame and the precision of the mask.

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0024] As mentioned in the background technology, the existing mask frame has the problem that it cannot be supported by air floatation. The inventors have found through research that the reason for this problem is: in order to reduce the weight of the mask frame, usually The surface of the mask frame facing the air flotation is provided with multiple weight-reducing grooves. Due to the existence of the weight-reducing grooves, the flatness of the surface of the mask frame facing the air flotation is low, so that t...

Abstract

Disclosed is a mask frame, comprising: a hollow area (10); and a frame area (20) surrounding the hollow area (10). The frame area (20) comprises a first surface (21) and a second surface (22) that are oppositely arranged, and the first surface (21) comprises a first step surface (211) surrounding the hollow area (10) and a second step surface (212) surrounding the first step surface (211); and the vertical distance between the first step surface (211) and the second surface (22) is larger than the vertical distance between the second step surface (212) and the second surface (22), the first step surface (211) is used for placing a mask, and the second step surface (212) is provided with a plurality of weight reduction grooves (30).

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a mask frame. Background technique [0002] The display panel usually needs to use a mask in the production process. The mask is usually fixed on the mask frame during evaporation. When the mask plate is fixed on the mask plate frame, a certain tension can be applied to the mask plate. [0003] In the prior art, when a preset force is applied to the mask frame, in order to reduce friction, the mask frame is usually placed on the air bearing, and the mask frame is supported by the air bearing. However, the existing mask There is a problem that the plate frame cannot be supported by air floatation, which affects the accuracy of subsequent preset force applied to the mask frame and the precision of the mask. Contents of the invention [0004] The present invention provides a mask frame to ensure that the air float can accurately prop up the mask frame,...
