## Abstract

Disclosed is an inspecting equipment for inspecting a light emission characteristic of a display screen includes: a carrying device provided for carrying the display screen, a cover device and a data analyzing device. The cover device has a detecting surface provided with a plurality of luminance detectors, and covers an emitting surface of the display screen to form a darkroom between the cover device and the detecting surface. A plurality of corresponding luminance information is generated by the luminance detectors provided for detecting a plurality of measuring zones of the emitting surface. The data analyzing device receives the luminance information and analyzes the light emission characteristic of the display screen according to the luminance information. And, it is thus able to rapidly inspect the light emission characteristic of the display screen during manufacture process, and is easy to be applied to a present producing line.
