Photosensor and display device including photosensor
摘要：
A photosensor is provided, which includes a sensor, a reference voltage generator and a processor. The sensor receives an external light and generates a sensing voltage in response to an amount of the external light received. The reference voltage generator is blocked from the external light and generates a reference voltage. The processor receives the sensing voltage from the sensor and the reference voltage from the reference voltage generator to generate a sensor output voltage in response to a difference between the sensing voltage and the reference voltage.
