A liquid crystal display color difference detection device and method

Abstract

The invention discloses a liquid crystal display color difference detection device and method, comprising a main casing, a sealed door, a connecting plate, a fixing bolt, a first electric push rod, a supporting plate, a supporting leg, a guiding cylinder, a guiding block, a guiding rod, Fixed plate, second electric push rod, colorimeter body, fixed column, fixed rod, rotating ring, rotating rod, fixed shell, adjusting bolt, moving block, fixed frame, spring, push rod, splint, placing board. This liquid crystal display color difference detection device and method is simple in structure and novel in design, which is convenient for workers to adjust the placement position of the main shell according to their own needs, and at the same time ensures the stable movement of the main shell during the adjustment process, which is convenient to meet the height of workers. , easy to use, under the action of the set clamping mechanism, it is convenient to stably clamp the LCD screen placed on the surface of the placement board, improve the stability of the LCD screen placement, and facilitate the workers to stabilize the LCD screen during the detection process Fixed, improved detection.

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
