Seal agent curing device

Abstract

The invention relates to the technical field of liquid-crystal display and discloses a seal agent curing device. The seal agent curing device comprises an ultraviolet laser and at least one optical fiber set; each optical fiber set comprises at least one ultraviolet optical fiber connected with the light-emitting end of the ultraviolet laser, and the light-emitting end of each optical fiber set faces a precured seal agent on a substrate. Due to the fact that the ultraviolet laser and ultraviolet optical fibers used for transmitting ultraviolet laser light are adopted, ultraviolet light output by the light-emitting end of each optical fiber set can directly irradiate the precured seal agent, energy waste caused by blocking the ultraviolet light through an existing mask plate is avoided, and the utilization rate of light energy is greatly enhanced. Besides, the mask plate does not need to be adopted in the seal agent curing device and does not need to be replaced when the substrate is replaced by a different substrate. Therefore, production efficiency can also be greatly improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a frame sealing glue curing device. Background technique [0002] Among the flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, relatively low manufacturing cost and low radiation, and occupies a dominant position in the current flat panel display market. leading position. Liquid crystal panel is the core component of TFT-LCD liquid crystal display. The core materials for making liquid crystal panels include alignment materials to realize liquid crystal alignment, liquid crystal materials that act as switches, and sealing glue that isolates liquid crystals from the outside world. At present, the box-making process often adopts the One Drop Fill (ODF) method. The method includes: first coating the liquid crystal material and the sealant on the surface of the array substrate...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned ultraviolet curing device for sealing glue, the ultraviolet light generated by the ultraviolet light source is distributed in a planar shape, and it is difficult to ensure the uniformity of the ultraviolet light intensity and the verticality of the ultraviolet light propagation path, and the area requiring ultraviolet curing is much smaller than In the area that needs to be shielded, most of the ultraviolet light is blocked by the mask plate, resulting in a waste of light energy, and when packaging different types of products, it is necessary to replace a new mask plate, and a vacuum adsorption system must be used to clean the mask plate. Fixing again, the process is complicated, and the process time is also long. Therefore, the defects of the prior art are that the utilization rate of light energy is low, and the production efficiency of the product is low.
