Abstract: The present disclosure is mainly related to a backlight detection device. The backlight detection device may comprise a film-pressing device and a vacuum equipment. The film-pressing device may be configured to place a film on a surface of a backlight. The vacuum equipment may be configured to evacuate a gap between the film and the surface of the backlight so that the film generates a pressure on the surface of the backlight.
