Problems solved by technology
Among them, under the same generation, the Frame (frame) used by Open Mask is designed with the same size, the only difference is that the Cover (shielding layer) welded on the Frame is different. The Cover and the upper surface of the Frame are welded and fixed. Grinding the upper surface of the Frame, but after multiple times of grinding, the overall height of the Frame will be reduced too much, so that it can no longer be used, and a new Frame needs to be replaced. The Frame in the prior art has a low reuse rate and a serious waste of resources

The invention relates to the technical field of display equipment, and discloses a supporting device of a mask plate. The supporting device of the mask plate comprises a plurality of bracket fixing seats and brackets in one-to-one correspondence with the bracket fixing seats, wherein the plurality of bracket fixing seats are sequentially connected end to end to form a closed annular structure, ineach pair of bracket and bracket fixing seat in one-to-one correspondence, the bracket is installed on the bracket fixing seat in the height direction of the bracket fixing seat in a position-adjustable mode, a mask plate welding face is formed on the top face of each bracket, when the mask plate is replaced, a new mask plate is welded after the mask plate welding face is polished, the thickness of the bracket in the height direction of the supporting device of the mask plate is reduced after repeated polishing, therefore, the overall height of the supporting device of the mask plate is reduced, and at the moment, the overall height of the supporting device of the mask plate can be adjusted by adjusting the installation height of the bracket on the bracket fixing seat so as to meet the requirement. The recycling times of the supporting device of the mask plate can be increased, so that the cost can be saved, and the resource waste is avoided.
Description
technical field [0001] The invention relates to the technical field of display equipment, in particular to a mask plate supporting device. Background technique [0002] Flat-panel displays include LCD displays, OLED displays, PDP displays, and electronic ink displays. OLED displays have the advantages of thinness, low power consumption, high contrast, high color gamut, and flexible display. It is the development trend of the next generation of displays. OLED displays include PMOLED and AMOLED displays. AMOLED displays are implemented in the following two ways. The first implementation uses LTPS (low temperature polysilicon) backplane and FMM Mask (fine metal mask) technology, and the second implementation uses Oxide (Oxide) backplane, WOLED (white organic electroluminescent device), and color film. The first implementation method is mainly applied to small-sized panels, corresponding to mobile phones and mobile applications; the second implementation method is mainly applie...
