Description

technical field [0001] The invention relates to an on-line testing device and a using method for the temperature performance of a liquid crystal display device, belonging to the technical field of electronic measurement. Background technique [0002] The liquid crystal display device has become a very widely used display device due to its characteristics of low voltage, low power consumption and small color distortion. However, since liquid crystal materials gradually become real crystals at extremely cold low temperatures, and become anisotropic substances or pure liquids at high temperatures, their physical properties are greatly affected by temperature. In the case of high temperature or low temperature, the luminosity and chromaticity parameters of the liquid crystal display device will change. [0003] At present, the existing liquid crystal display device temperature performance testing device adopts an off-line test method, that is, the liquid crystal display device ...
