Embodiment Construction

[0019] The main purpose of this application is: use the baffle to limit the glue to the area to be coated on the substrate, vibrate the substrate injected with glue, and use the fluidity of the glue to make the glue evenly distributed in the area to be coated. When the baffle is removed, a colloid with uniform thickness can be formed, which is beneficial to meet the coating requirements of the flexible display device for the colloid.

[0020] The following clearly and completely describes the technical solutions of each exemplary embodiment provided in the present application with reference to the drawings in the embodiments of the present application. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other. Moreover, the directional terms used throughout the application, such as "up", "down", etc., are for better describing the technical solutions of various embodiments, and are not used to limit the protection sco...

Abstract

The invention discloses a colloid coating method and a colloid coating device. The colloid coating method comprises the following steps: setting a baffle plate perpendicular to a base plate to ensurethat the baffle plate is arranged above the upper surface of the base plate and a to-be-coated area is defined on the base plate; injecting glue into the to-be-coated area; shaking the base plate intowhich the glue is injected; solidifying the glue; removing the baffle plate. Based on that, the colloid coating method and the colloid coating device disclosed by the invention have the advantages that the colloids with uniform thickness can be formed, and a coating requirement of a flexible display device on the colloids is met.

Description

technical field [0001] The present application relates to the field of display, in particular to the field of packaging of electronic devices, and in particular to a colloid coating method and a colloid coating device. Background technique [0002] In the traditional colloid coating process, the glue is dripped on the area to be protected, and then cured. The cured colloid can play the role of water vapor barrier and anti-corrosion. combine figure 1 and figure 2 As shown, the glue 11 dripped into the predetermined area has a dome-shaped structure, the thickness of the middle part is larger, and the thickness of the two sides is smaller, and, in order to prevent the glue from peeling off (peeling) or breakage caused by overflow glue, the glue 11 It will not be applied to the edge positions of the substrate (such as a display panel) 12 , such as the edge positions on the left and right sides shown in the figure. Therefore, the cured colloid also has a dome-like structure w...
