Abstract

The invention provides a mask plate net stretching assembly, a net stretching device and a net stretching method, the mask plate net stretching assembly, the net stretching device and the net stretching method are used for stretching a mask plate on a mask frame, the mask plate comprises two welding areas located at the two opposite ends of the mask plate, each welding area comprises a first faceand a second face which are opposite, and the mask frame comprises two opposite first side edges; the first surface is attached to the surface of the first side edge of the mask frame; the mask platenet stretching assembly comprises a main frame which comprises a pressing plane used for pressing a second face of a welding area and a back face opposite to the pressing plane, and a hollow area penetrating through the pressing plane and the back face is arranged in the middle of the main frame; and the force application structure is arranged on the main frame and applies a first pressing actingforce and a second pressing acting force to the two opposite ends of the main frame correspondingly, and the directions of the first pressing acting force and the second pressing acting force are perpendicular to the pressing plane and are the same. According to the mask plate net stretching assembly, the net stretching device and the net stretching method provided by the invention, defects causedby wrinkles of mask plate net stretching can be overcome.

Description

technical field [0001] The invention relates to the technical field of display manufacturing, in particular to a mask template stretching component, a stretching device, and a stretching method. Background technique [0002] OLED (Organic Light-Emitting Diode, also known as organic laser display, organic light-emitting semiconductor) has fast response time, large viewing angle, high contrast, light weight, and low power consumption. It is considered to be the most promising flat panel display device , and is considered to be the display technology most likely to be made into a flexible display device. The luminescent material of the AMOLED display is mainly deposited on the display substrate by using a fine metal mask (Fine Metal Mask, FMM). FMM opening is an important part of OLED production, and the effect of opening greatly determines the yield rate of OLED evaporation process. [0003] In related technologies, the FMM stretching process is as follows: the mask is stret...
