Source driver and a display driver integrated circuit

A display driver integrated circuit (IC), comprising:

• a source driver which drives a data line of a display panel;
• a gate driver which drives a gate line of the display panel;
• and
• a controller which controls the source driver and the gate driver,
• wherein the source driver includes a first capacitor, a second capacitor and a channel buffer, and
• the channel buffer includes:
• a first source line;
• a second source line;
• a charge sharing switch which controls a connection between the first source line and the second source line;
• a first cross charge sharing switch which controls a connection between the first capacitor and the first source line, and a connection between the second capacitor and the second source line, wherein the first capacitor is connected to a first cross charge sharing line through a first terminal and the second capacitor is connected to a second cross charge sharing line through a second terminal;
• and
• a second cross charge sharing switch which controls a connection between the first capacitor and the second source line, and a connection between the second capacitor and the first source line.

A source driver, comprising:

• a first source line connected to a first terminal, a second source line connected to a second terminal, a third source line connected to a third terminal and a fourth source line connected to a fourth terminal;
• a plurality of charge sharing switches which control connections of the first source line, the second source line, the third source line and the fourth source line to each other;
• a plurality of first cross charge sharing switches which control connections between a first capacitor, the first source line and the third source line, and connections bet wen a second capacitor, the second source line and the fourth source line, wherein the first capacitor is connected to a first cross charge sharing line through a fifth terminal and the second capacitor is connected to a second cross charge sharing line through a sixth terminal;
• and
• a plurality of second cross charge sharing switches which control connections between the first capacitor, the second source line and the fourth source line, and connections between the second capacitor, the first source line and the third source line.
