摘要：
An exemplary light sensor (20) includes a supporting base, a light-sensing unit (21) provided at at least one first location of the supporting base where ambient light is received, and a compensating unit (22) provided at a second location of the supporting base shielded from ambient light, the compensating unit having a structure that is the same as the light-sensing portion. The light-sensing portion includes at least one amorphous silicon thin film transistor (TFT) (210) configured for sensing light, and the compensating unit is configured for providing a reference value current for the light-sensing unit. A display device using the light sensor is also provided.
