Abstract
An optical sensor circuit is provided. In the optical sensor circuit, an output stage circuit transmits a voltage of first and second node to the output line according to a first driving signal. A first sensor is configured to generate a first photocurrent according to a first color light that senses an ambient light, and generate a second photocurrent according to a second color light. A second sensor is configured to generate a third photocurrent according to a third color light, and generate a fourth photocurrent according to the second color light. In a sensing phase, when the first sensor senses the first color light, and the second sensor senses the third color light, the first sensor adjusts a voltage level of the voltage according to the first photocurrent, and the second sensor adjusts the voltage level of the voltage according to the third photocurrent.
