Bonding glue mixture, bonding glue detecting device, display panel and preparation method of display panel

Abstract

The invention provides a bonding glue mixture, a bonding glue detecting device, a display panel and a preparation method of the display panel. The bonding glue mixture comprises bonding glue and a plurality of filling particles which are distributed in the bonding glue, wherein the distribution range of the filling particles can be detected and differentiated by virtue of a matched detecting instrument at a set detection environment. The bonding glue detecting device comprises a magnetic field generating unit and a magnetic field range detecting unit. The display panel comprises a first substrate and a second substrate, wherein the first substrate and the second substrate are closed together and are bonded together through the bonding glue. The preparation method comprises the following steps: coating the first substrate with the bonding glue mixture; closing the second substrate and the first substrate together; precuring the bonding glue mixture, detecting the distribution range of the filling particles by virtue of the matched detecting device, and acquiring the coverage range of the bonding glue according to the distribution range of the filling particles, so as to judge the coating effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an adhesive mixture, an adhesive detection device, a display panel and a preparation method. Background technique [0002] The development of liquid crystal display panels is changing with each passing day, and has become an indispensable part of people's lives. Due to its advantages of large viewing area, uniform and compact volume, low-voltage micro-power consumption, flat-panel structure, passive display, large amount of displayed information, easy colorization, no electromagnetic radiation, and long life, the fields involved in liquid crystal display panels are also gradually expand. With the continuous update of technology and equipment, its display effect has been greatly improved, bringing great convenience to our life and work.

AI Technical Summary

Problems solved by technology

[0004] The unsatisfactory width and uniformity of the sealing glue will lead to glue leakage, easy entry of water vapor, puncture of the sealing glue, pollution of the liquid crystal, and abnormal gaps around the periphery, etc., especially when it is put into the process for the first time, the coating effect cannot be guaranteed.
