[0001] The utility model relates to the technical field of liquid crystal screens, and in particular to a rotary clamp for detecting liquid crystal screens. Background Art

[0002] Liquid crystal screens use liquid crystal material as their basic component. Liquid crystal material is filled between two parallel plates. Voltage is used to change the arrangement of the molecules within the liquid crystal material to achieve the purpose of light blocking and light transmission, displaying images of varying depths and shades. Furthermore, by adding a three-color filter layer between the two plates, color images can be displayed. LCD screen testing includes power supply capacity testing, performance testing, brightness testing, color testing, power consumption testing, interface testing, anti-interference testing, impact testing, and collision testing.
