Abstract

The invention relates to a detecting device, which is suitable for detecting the angle of a light absorption axis of a first polarizer of a liquid crystal panel, and the liquid crystal panel comprises a first baseplate, a second baseplate and a liquid layer. The detecting device includes a light source, a rotatable detecting polarizer and a light detector. The light source is arranged at one side of the liquid crystal panel, and the liquid crystal panel is arranged on the optical path of the light source. The rotatable detecting polarizer is arranged at the other side of the liquid crystal panel and is arranged on the optical path of the light source, and the first polarizer is arranged between the baseplate and the rotatable detecting polarizer. The optical detector is arranged on the optical path of the light source, and the optical detector and the first polarizer are respectively arranged at two sides of the rotatable detecting polarizer; so using the detecting device can rapidly detect the angle of the light absorption axis of the first polarizer.

Description

technical field [0001] The present invention relates to a detection device and a detection method, and in particular to a detection device and a detection method for detecting the angle of the absorption axis of a polarizer of a liquid crystal panel. Background technique [0002] With the increasingly developed electronic industry, flat panel displays have eliminated cathode ray tube displays and become the current mainstream. Among the flat panel displays, the liquid crystal display technology is the most mature and popular. Among them, the LCD panel is the key to the quality of LCD monitors. [0003] figure 1 It is an exploded schematic diagram of an existing liquid crystal panel. Please refer to figure 1 The liquid crystal panel 100 includes a first polarizer 110 , a first substrate 120 , a second substrate 130 , a liquid crystal layer 140 and a second polarizer 150 . The liquid crystal layer 140 is located between the first substrate 120 and the second substrate 130...
