Display device and driving method thereof

A display device, comprising:

• a display panel comprising a plurality of gate lines;
• and
• a gate lines driver configured to receive a gate clock signal and an output enable signal, the output enable signal having a first level and a second level, the gate lines driver being further configured to output respective gate line driving signals to respective ones of the plurality of gate lines,
• wherein the gate lines driver comprises a level shifter configured to output a first gate line driving voltage or a second gate line driving voltage different from the first gate line driving voltage when the output enable signal is the first level, and to output a third gate line driving voltage having a level between those of the first and second gate line driving voltages when the output enable signal is the second level.

A method of reducing a time for switching a gate line driving signal of display device having plural gate lines from a level that is less than a full gate-on level to the gate-on level, the method comprising:

• during a gate line pre-charging period of respective gate line, causing the gate line driving signal of the respective gate line to be at the full gate-on level;
• during a corresponding gate line main-charging period that follows the pre-charging period, causing the gate line driving signal of the respective gate line to be at the full gate-on level;
• and
• during an interposed period that is interposed between the gate line pre-charging period and its corresponding gate line main-charging period, causing the gate line driving signal of the respective gate line to be at an intermediate level that is between the full gate-on level and an opposed gate-off level;
• wherein the full gate-on level causes corresponding pixel switching elements of the display device to which that level is applied to be in a low resistance, saturated mode;
• wherein the gate-off level causes the corresponding pixel switching elements of the display device to which that level is applied to be in a sub-threshold turned-off mode;
• wherein the intermediate level causes the corresponding pixel switching elements of the display device to which that level is applied to be in an intermediate resistive mode having a resistance between that of turned-off mode and that of the low resistance, saturated mode;
• and
• wherein a time for transitioning the gate line driving signal from the intermediate level to the full gate-on level is substantially less than a time for transitioning the gate line driving signal from the gate-off level to the full gate-on level.
