Abstract
The utility model is applied to the field of detection devices of panel display screens, particularly to a lighting device applied to automatic optical detection of a panel display screen. The lighting device comprises a backlight source, side light sources and a bearing mechanism, wherein the backlight source is positioned at the bottom of a display screen to be detected; the side light sources are positioned at two sides of the display screen to be detected; and the bearing mechanism is used for bearing the backlight sources and the side light sources. The lighting device applied to automatic optical detection of the panel display screen, provided by the embodiment of the utility mode, is capable of meeting the requirements on image brightness variation and uniformity of the display screen after the display screen to be detected lights up and reaching the purpose of lighting dust. The dust is effectively filtered through a detection algorithm and the defect of electric testing performance of the display screen is identified.
