Problems solved by technology

However, this kind of inspection process will bring the following problems: first, the entire inspection process needs to be carefully inspected step by step, resulting in an extremely slow inspection process; second, if the moving speed of the green light source is not synchronized with the eye's observation range, it is easy to miss area, thus leaving a quality hazard; third, the green light is reflected by the LCD panel and enters the inspector's eyes, which can damage the eyes for a long time

Embodiment Construction

[0016] The present invention will be further described below.

[0017] The frame rubber raw material of the liquid crystal panel is actually the raw material for making the sealant frame, and the frame rubber material of the liquid crystal panel of the present invention is mainly improved on the basis of the conventional frame rubber material. In the past, frame rubber raw materials were mainly composed of organic resins, photoinitiators, coupling agents, thermosetting agents and fillers. The frame glue material of the liquid crystal panel of the present invention adds a non-repelling fluorescent agent to the previous components, that is, the frame glue material of the liquid crystal panel of the present invention includes a base material (mainly an organic resin), a photoinitiator, and a coupling agent , heat hardeners, fillers and fluorescent agents. Among them, the non-repelling fluorescent agent refers to a fluorescent agent with fine particles ≤ 4 μm that does not chemic...

Abstract

The invention relates to a frame adhesive raw material of a liquid crystal display panel and a sealed adhesive frame of the liquid crystal display panel which is manufactured by the frame adhesive raw material. The frame adhesive raw material comprises a base material and a non-rejected fluorescent agent. The frame adhesive raw material of the liquid crystal display panel contains the fluorescent agent, so that uncured sealed adhesive frames which are coated by the frame adhesive raw material have luminescence function, and coating status of the frame adhesive raw material is easy to observed or acquired by inspection personnel or inspection equipment through light of the frame adhesive raw material; during the period, external light sources are not needed, so that operation difficulty for the inspection personnel is reduced, the detection process becomes simple and rapid, zone to be checked is not easy to omit, and damage to eyes is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of a thin film transistor liquid crystal display (TFT-LCD for short), and specifically relates to a frame glue material of a liquid crystal panel and a sealant frame manufactured from the frame glue material. Background technique [0002] As an important material in TFT-LCD, the frame rubber raw material of LCD panel plays a key role in the TFT-LCD industry. The main purpose of the frame glue raw material is to paste two glass substrates together and solidify between the two glass substrates into a high-strength sealant frame to avoid leakage of liquid crystal injected between the two glass substrates and prevent Harmful substances such as water vapor and dust from the outside enter and contaminate the liquid crystal. [0003] When inspecting the coating status of the sealant frame of the liquid crystal panel, due to the poor transparency of the glass substrate, inspectors cannot directly observe it, so it ...
