Abstract

The invention discloses a liquid crystal display yellow spot detection device and method. The device comprises an adsorption component and a negative pressure pipeline communicated with the adsorption component at a minimum, and the negative pressure pipeline is further connected with a negative pressure source; the negative pressure pipeline is used for supplying negative pressure generated by the negative pressure source to the adsorption component and maintaining the stable negative pressure value, so that the adsorption component can be adsorbed to the light emergence surface of a powered-up liquid crystal display to be detected and last for first preset duration and stop supplying negative pressure to the adsorption component after the first preset duration is ended. By means of the liquid crystal display yellow spot detection device, the pressure to which the liquid crystal display is subjected after a touch screen is attached to the display can be simulated, the liquid crystal display which possibly generates yellow spots is detected out in advance, and the manufacturing yield rate of liquid crystal display panels is effectively raised.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a macular detection device and a detection method of a liquid crystal display. Background technique [0002] Display, according to different manufacturing materials, can be divided into: cathode ray tube display (CathodeRayTube, CRT), plasma display (PlasmaDisplayPanel, PDP), liquid crystal display (LiquidCrystalDisplay, LCD), organic light-emitting diode display (OrganicLight-EmittingDiode, OLED), etc. . Compared with other displays, LCD has the advantages of right-angle display, low power consumption, small size and zero radiation, allowing users to enjoy a better visual environment. [0003] However, in the actual manufacturing process of the liquid crystal display panel, due to the limitation of technology and equipment, the liquid crystal display panel formed after the liquid crystal display screen is bonded with the touch screen often appears yellowish. figure 1 with...
