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...
