摘要： 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.

摘要： A pixel circuit including a compensation circuit, a writing circuit, a light emitting element, and a power supplying circuit is provided. The compensation circuit comprises a first node, and provides a driving current to the light emitting element according to a voltage of the first node and a system high voltage. The writing circuit provides a data voltage to the compensation circuit according to a first control signal so that the compensation circuit sets the voltage of the first node. The power supplying circuit selectively couples the compensation circuit to the light emitting element, and provides the system high voltage and a system low voltage to the compensation circuit, in which the system low voltage is configured to reset the voltage of the first node. The first control signal and the second control signal are opposite to the first emission signal and the second emission signal, respectively.
