Abstract
A pixel circuit including a writing circuit, a compensation circuit, a reset circuit, a brightness control circuit, and a light emission control circuit is provided. The writing circuit provides a first data signal and a second data signal. A first compensation unit of the compensation circuit provides, in a first time period, a first driving current according to the first data signal. A second compensation unit of the compensation circuit provides, in a second time period separated from the first time period, a second driving current according to the second data signal. The reset circuit provides a reference voltage to the compensation circuit. The light emission control circuit conducts the first compensation unit to the brightness control circuit in the first time period, and conducts the second compensation unit to the brightness control circuit in the second time period.
