Device and method for detecting color difference of liquid crystal display screen

Abstract

The invention discloses a device and method for detecting color difference of a liquid crystal display screen. The device for detecting color difference of the liquid crystal display screen includes amain casing, a sealed door, a connection plate, a fixing bolt, a first electric push rod, a support plate, a support leg, a guide cylinder, a guide block, a guide rod, a fixing plate, a second electric push rod, a colorimeter body, a fixing column, a fixing rod, a rotating ring, a rotating rod, a fixing shell, an adjusting bolt, a moving block, a fixing frame, a spring, a push rod, a clamping plate, and a placing plate. According to the device and method for detecting the color difference ofthe liquid crystal display screen, the structure is simple, the design is novel, the placement positionof the main casing can be conveniently adjusted according to the needs of a worker, at the same time, stable movement during the adjustment of the main casing is ensured, height of the worker is conveniently met, using is convenient, the liquid crystal display screen placed on the surface of the placing plate is conveniently stabilized and clamped under the action of an arranged clamping mechanism, stability of the placement of the display screen is improved, stable fixation of the liquid crystal display screen during the detection is facilitated for workers, and the detection result is improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a liquid crystal display color difference detection device and method, belonging to the technical field of liquid crystal display color difference detection applications. Background technique [0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors (TFT). It mainly uses current to stimulate liquid crystal molecules to generate points, lines, and surfaces to form a picture with the back lamp tube; IPS, TFT, and SLCD all belong to LCD. Subclass; the working principle of the liquid crystal display is: under the action of the electric field, the alignment direction of the liquid crystal molecules is changed to change (modulate) the light transmittance of the external light source, complete the electro-optical conversion, and then use the R, G, B three The different excitations of the primary color signals pass through the red, green, and blue pri...

AI Technical Summary

Problems solved by technology

[0003] There are many problems in the detection process of the existing liquid crystal display. When the existing liquid crystal display is detected, the fixing effect of the liquid crystal display is not very ideal, which will easily cause the liquid crystal display to shift during the rotation process, which will easily lead to the detection of the display screen. At the same time, the height of the detection table is stable, which is not convenient for workers of different heights to detect, which affects the use
