Abstract
A control circuit includes a power supply switch unit and a reset switch unit. The power supply switch unit is electrically connected to a data line and a pixel circuit. When the data line has a data voltage, the power supply switch unit is turned on according to a power supply signal, so that the pixel circuit is charged by the data voltage. The reset switch unit is electrically connected to the pixel circuit. After the pixel circuit is charged by the data voltage, the reset switch unit is turned on according to the reset signal to reset a voltage of the pixel circuit to the reset voltage.
