Touch detectable display device and driving method thereof

A display device comprising:

• a display panel;
• a lighting unit adapted to illuminate the display panel in response to receipt of a lighting control signal;
• a pressure sensing unit adapted to generate a first sensor output signal in response to a touch on the display panel;
• a light sensing unit positioned to receive light from the lighting unit and ambient light and in response thereto to generate a second sensor output signal in response to a touch on the display panel;
• a sensor scanning driver adapted to generate and supply sensor scanning signals to the pressure sensing unit and to the light sensing unit in response to receipt of a sensor scanning control signal;
• and
• a signal controller being operable to generate the lighting control signal and the sensor scanning control signal in response to receipt of the first and the second sensor output signals, the signal controller being further operable to generate the lighting control signal, the sensor scanning control signal.
