Abstract

The invention discloses a mask plate installing frame and a mask plate assembly and relates to the technical field of mask plates to be used for solving the problem that a mask plate installing framein the related art cannot well adapt to changing of the width of a mask plate. The mask plate installing frame comprises a frame body and a plurality of first fixed units; the plurality of first fixedunits are all arranged on the frame body and are distributed in the first direction in a spaced manner; the frame body is provided with an opening; each first fixed unit comprises two first sub-fixedunits movably connected with the frame body; in the second direction, every two first sub-fixed units are correspondingly located on the two sides of the opening and are oppositely arranged; each first sub-fixed unit comprises a first body and a first connection portion arranged on the first body; each first connection portion is used for being connected with a mask plate; and in the first direction and the second direction, the positions of the first connection portions relative to the frame body are adjustable. The mask plate installing frame and the mask plate assembly can be used for netexpanding adjustment of the mask plate.

Description

technical field [0001] The invention relates to the technical field of mask plates, in particular to a mask plate mounting frame and a mask plate assembly. Background technique [0002] Organic electroluminescent (OLED, Organic Light-Emitting Diode) devices have many advantages such as self-luminescence, fast response time, wide viewing angle, low cost, simple manufacturing process, good resolution and high brightness, and are considered to be the next generation of planar Emerging application technologies for displays. In the production process of OLED devices, vacuum evaporation is an important process. OLED organic evaporation uses a high-precision mask as a mold. After the organic material is volatilized at high temperature, it passes through the effective opening area of ​​the mask in the state of material molecules. The mask openings are evaporated onto the backplane glass. Among them, the flatness of the mask directly affects the effect of evaporation. The higher th...
