Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] Such as figure 1 As shown, the film laying device 1 provided by the embodiment of the present invention includes an inkjet 10 , a carrier plate 12 and a heater 14 . The carrying plate 12 is used to carry the substrate 2 on which the film layer needs to be laid. The inkjet 10 sprays the film layer material 3 on the substrate 2 according to the preset spray amount and step speed. The heater 14 heats the film material 3 to a preset temperature range during th...

Abstract

The embodiment of the invention discloses a film laying device, comprising an ink sprayer, a bearing plate and a heater, wherein the bearing plate is used for bearing a substrate on which a film is to be laid; the ink sprayer is used for spraying a film material on the substrate according to a preset spraying amount and a preset stepping rate; and the heater is used for heating the film material to a preset temperature range in a process of spraying the film material, so as to reduce uneven diffusion due to a surface tension difference of the film material. Furthermore, the invention provides a film laying method using the device.

Description

technical field [0001] The invention relates to film layer laying technology, in particular to a film layer laying device and method for improving film layer uniformity. Background technique [0002] Most of the existing display panel manufacturing processes use inkjet technology to drop alignment film liquid on the glass substrate, and then use the surface tension of the alignment film liquid itself to diffuse and connect to form a film. However, due to the difference in the surface tension of the alignment film liquid, there will be uneven diffusion, resulting in poor uniformity of the thickness of the alignment film, which will affect the optical quality of the display panel. [0003] Therefore, it is necessary to provide a film laying device capable of solving the above problems and a film laying method using the same. Contents of the invention [0004] In order to solve the above technical problems, an embodiment of the present invention provides a film laying device...
