Recognition device and alignment system
Embodiments of the present invention provide a recognition device and an alignment system. The recognition device is configured to recognize an alignment mark on a display substrate and comprises a camera unit and a light source unit. The camera unit is configured to shoot the alignment mark, and the light source unit is configured to radiate emitted light onto the alignment mark. The recognition device further comprises a light processing unit configured to process light emitted from the light source unit so that the luminance of the light irradiated onto the alignment mark is greater than that of the light emitted from the light source unit. Through the arrangement of the light processing unit, the recognition device enables the luminance of the light irradiated onto the alignment mark to be greater than that of the light emitted from the light source unit.
