The present disclosure discloses a display driving circuit. The display driving circuit is configured to have a function of detecting a short of a data line occurring on a display panel.

Display driving circuit having short detection function

The present disclosure discloses a precharge circuit capable of compensating for a resistance deviation between channels so that sense lines of a display panel can be uniformly charged and a source driver including the same. The precharge circuit may include a voltage terminal configured to provide a reference voltage, a common line connected to the voltage terminal, and channel lines connected to the common line and configured to transfer, to respective sense lines of a display panel, the reference voltage transferred through the common line.

Precharge circuit and source driver including the same

The present disclosure discloses a display driving apparatus. The display driving apparatus of the present disclosure may be configured to drive a source signal in a state optimized for a panel load of a display panel.

Display driving apparatus

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.
