The invention discloses a light guide plate detection apparatus, which includes a mounting fixing stand, a detection platform, a side light source apparatus, a camera support and a camera. The detection platform, the side light source apparatus and the camera support are connected with and fixed to the top surface of the mounting fixing stand. The camera support is connected with and fixes the camera. The detection platform includes a support, a table top, an LED light strip, an LED light shielding plate, a reflective mirror and the side light source apparatus. The apparatus is used for detecting the optical performance and the brightness uniformity of a light guide plate, and detecting whether the light guide plate has dirt, bright spots, other impurities, burrs, scratches and other appearance defects, so people can then determine whether the detected light guide plate can be put into use. The light guide plate detection apparatus is high in detection efficiency and high in automation, has a simple structure, and exhibits the stable and reliable performance. Moreover, dust on the light guide plate can be eliminated and prevented from affecting a light guide plate detection result.
Description
technical field [0001] The invention relates to the field of detection equipment, in particular to a light guide plate detection device. Background technique [0002] The backlight is a light source device used to ensure that the back of the LCD screen emits light. Because the liquid crystal display itself is transparent and does not emit light, it needs a backlight to assist. Some indicators such as the brightness and uniformity of the backlight have a direct impact on the performance of the liquid crystal display. The light guide plate is the transmission medium of the backlight light source, and its shape and material composition determine the brightness and distribution uniformity of the light exit surface. The function of the light guide plate is to convert the side light source into a surface light source and emit light evenly. At present, the common applications of light guide plates are: backlight of liquid crystal display, mobile phone display, ultra-thin adver...
