The invention discloses a small-sized liquid crystal screen electric-control lighting-on detection method which is achieved by utilizing a small-sized liquid crystal screen electric-control lighting-on detection device. The small-sized liquid crystal screen electric-control lighting-on detection device comprises a rack, a display and a working table top, wherein a detection unit and a signal machine are arranged on the working table top, position limiting of different sizes of small-sized liquid crystal screens is achieved through the joint effect of a movable positioning block, a fixed positioning block and / or semi-fixed positioning block on the detection unit, detection of different positions is achieved through the joint effect of a universal adjusting mechanism and a universal adjusting knob, and the small-sized liquid crystal screen electric-control lighting-on detection process is achieved. By adopting the small-sized liquid crystal screen electric-control lighting-on detection method, accurate electric-control lighting-on detection of the small-sized liquid crystal screens with the sizes smaller than 8 inches is achieved, and detection of different sizes of liquid crystal screens can be also achieved. In addition, detection of liquid crystal screens at different positions is also achieved by adopting the detection method, and thus the detection accuracy is improved.
Description
technical field [0001] The invention belongs to the field of liquid crystal screen detection, and in particular relates to a small-size liquid crystal screen electric control lighting detection method. Background technique [0002] With the rapid development of flat panel displays and the improvement of people's living standards, liquid crystal display screens have been widely used in daily life and industrial production, and their application fields and application forms are becoming more and more diverse. [0003] With the continuous expansion of the application field of LCD screens and the continuous improvement of people's requirements for the picture quality of LCD screens, the picture inspection after the production of LCD screens is becoming more and more important. However, due to the defect that the traditional LCD screen detection device can only detect one-to-one size, it is difficult to detect LCD screens of different sizes, and it is impossible to detect LCD scr...
