2 more elements
A touch screen apparatus, comprising:
- a touch screen having first and second touch sensing units, wherein the first touch sensing unit measures a touch position of a touch input object and the second touch sensing unit measures a touch force of the touch input object;
- a temperature sensing unit having a temperature sensor measuring a temperature of the touch screen;
- and
- a touch driving circuit connected to the touch screen, generating touch position data and touch force level data, and correcting the touch force level data in accordance with the measured temperature at the temperature sensing unit,
- wherein the temperature sensor is connected to touch driving circuit when a first touch is detected at the first and second touch sensing units after the touch screen is in a sleep mode and connected to ground when no touch input object is detected at the first and second touch sensing units.
