A kind of intelligent equipment and detection method for fast and automatic batch testing of transparent liquid crystal screen haze consistency

Abstract

The invention provides an intelligent device and a detection method for quickly and automatically testing the haze consistency of transparent liquid crystal screens in batches. The mold is placed in the light-emitting place and moved by an assembly line. A test camera is arranged on one side of the assembly line, and a parallel light source array is arranged on the other side of the assembly line. A transparent liquid crystal screen translation device to be tested is arranged between the test camera and the parallel light source array. , the transparent liquid crystal screen to be tested is moved between the test camera and the parallel light source array through the translation device of the transparent liquid crystal screen to be tested, and a computer is arranged beside the test camera. In the production of transparent LCD screens, testing the scattering effect of parallel light after penetration of transparent liquid crystal screens has the advantages of fast, automatic and cheap. It can achieve rapid and full inspection of the assembly line, improve inspection efficiency, ensure inspection accuracy, and provide detailed inspection. steps to ensure the accuracy of the detection.

Description

technical field [0001] The invention relates to the field of transparent liquid crystal screen production, in particular to an intelligent device and a detection method for quickly and automatically batch testing the haze consistency of transparent liquid crystal screens. Background technique [0002] In December 2012, at the IEC / TC110 working group meeting held in Kyoto, Japan, Chinese representatives put forward a proposal to formulate an international standard for "Optical Test Methods for Transparent Liquid Crystal Displays". After nearly two years of discussions, the proposal was approved in November 2014. At the IEC / TC110 working group meeting held in Tokyo, Japan, the working group voted, and it was agreed that the Chinese National Committee would formally submit an application for a new work project. The proposal plays a very important role in improving the international standard system of transparent display and promoting the development of my country's transparent ...

AI Technical Summary

Problems solved by technology

The method in the proposal is rigorous and reliable in theory, but its shortcomings are obvious. It not only has high environmental requirements, but also is extremely slow, and cannot be used for online detection of semi-finished products. In reality, this haze meter is very expensive and expensive. hundreds of thousands of yuan
