Embodiment Construction

[0071] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0072] figure 1 A schematic flow chart of the quality detection method for liquid crystal screens provided in the first embodiment of the present invention, as shown in figure 1 shown, including the following steps:

[0073] Step 101: Detecting the liquid crystal screen, and acquiring optical parameters of the liquid crystal screen;

[0074] Here, the acquiring the optical parameters of the liquid crystal screen includes: acquiring the brightness value, chromaticity value and color temperature value of the liquid crystal screen;

[0075] Specifically, the liquid crystal screen to be tested is illuminated by a fixed light source, and the surface of the liquid crystal screen is scanned by optical lenses in different directions to obtain optical parameters such as brightness value, chromaticity value, and color temperature value of the...

Abstract

A quality detection method for a liquid crystal screen comprises: acquiring an optical parameter of a liquid crystal screen; collecting an image of the liquid crystal screen; and if it is determined that the optical parameter is not in a preset optical parameter range and / or the collected image of the liquid crystal screen is inconsistent with a pre-stored image, determining that the liquid crystal screen is unqualified. By means of the method, unqualified types of products can be effectively distinguished, and unqualified locations of products can be recorded, thereby effectively reducing misjudgment or missed inspection due to vision disparity of human, so as to improve the outgoing quality and yield of the products. Further provided is a quality detection apparatus for a liquid crystal screen.

Description

technical field [0001] The invention relates to a liquid crystal screen quality detection technology, in particular to a liquid crystal screen quality detection method, device and equipment. Background technique [0002] In the traditional LCD screen technology, the stages of defective detection of LCD screen products and the final judgment of the level of LCD screen products are all manual operations. However, due to differences in human vision or human factors, misjudgments and missed inspections of LCD screen products may occur, affecting the factory quality and yield of LCD screen products. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a quality inspection method, device and equipment for liquid crystal screens, which can effectively distinguish the defective type of the product and record the defective position of the product, thereby effectively reducing errors caused by human visual differences, etc. Mis...
