Film transfer printing equipment, transfer printing plate assembly, and adsorption force control device for transfer printing equipment

Abstract

The invention provides film transfer equipment, a transfer plate assembly and a transfer equipment adsorption force control device. The film transfer equipment comprises a transfer plate used for transferring a film layer to a base plate for the film layer to be transferred, and a base station used for bearing the base plate. The film transfer equipment further comprises an adsorption force control unit, wherein the adsorption force control unit acts on at least one of the base plate and / or the transfer plate in the transferring process so as to increase the difference between first adsorption force of the base plate to film forming matter transferred out from the transfer plate and second adsorption force generated by the transfer plate to the film forming matter. The film transfer equipment, the transfer plate assembly and the transfer equipment adsorption force control device can reduce residue and particle phenomena in the transferring and film forming processes through a simple and low-cost method.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a film transfer printing device, a transfer printing plate assembly, and a device for controlling the adsorption force of the transfer printing device. Background technique [0002] Film-forming technology is a commonly used technology in the field of liquid crystal display manufacturing, and film-forming by transfer printing plate is a common film-forming process. However, during the transfer film forming process, due to the film-forming substance solution is prone to residue when transferring from the surface mesh of the transfer plate to the substrate surface, and the remaining film-forming substance solution is easy to form particulate matter in the continuous production process Adhesion to the subsequent film layer makes it difficult to control the thickness of the subsequent film layer and the particulate matter on the film surface. Optimizing and improving ...

Problems solved by technology

However, during the transfer film forming process, due to the film-forming substance solution is prone to residue when transferring from the surface mesh of the transfer plate to the substrate surface, and the remaining film-forming substance solution is easy to form particulate matter in the continuous production process Adhesion to subsequent film layers, making subsequent film thickness and surface particulate matter difficult to control at all times

Optimizing and improving the material and mesh structure of the transfer printing plate is a common technical means to solve the above problems in the prior art. However, the cost of improving the material or mesh structure of the transfer printing plate is high and the flexibility is low. It is suitable for different substrates and different The film-forming substances are not targeted
