Abstract
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.
Claims16
A display driving apparatus comprising:
- an output buffer configured to output a source signal corresponding to display data to a display panel;
- and
- a panel load detection circuit configured to determine an amount of a panel load of the display panel to which the source signal is to be provided, and output a control signal corresponding to a level of a comparison signal generated by comparing a charging voltage of the panel load with a preset reference voltage,
- wherein the output buffer outputs the source signal with an amount of current corresponding to the amount of the panel load, by the control signal.
