Patent abstract
The present disclosure relates to a pixel circuit and pixel driving apparatus technology. In this technology, two LEDs are arranged in parallel and selectively used in a hybrid manner in which a PWM (pulse width modulation) scheme for supplying a ramp voltage as a gate voltage for a transistor arranged within a pixel and for turning off the LEDs at the moment when the gate voltage becomes equal to a threshold voltage and a PAM (pulse amplitude modulation) scheme for determining a starting value of the ramp voltage based on a grayscale value of the pixel are combined.
