Temperature sensor and display device including the same

A display device comprising:

• a touch sensing unit configured to sense a user's touch input;
• a display panel disposed on the touch sensing unit, including a display area and a non-display area, and wherein the display panel is configured to display an image in the display area;
• and
• a temperature sensor configured to calculate a temperature value in correspondence with the user's touch input,
• wherein the temperature sensor includes:
• a first sensor including a sensing element, wherein the first sensor is configured to measure a first resistance value of the sensing element in a first state, and wherein the first sensor is configured to measure a second resistance value of the sensing element in a second state different from the first state;
• a second sensor configured to measure a touch pressure corresponding to the touch input in the second state;
• a compensator configured to calculate a first change rate based on the first resistance value and the second resistance value, and wherein the compensator is configured to calculate a change rate of a correction resistance value by correcting the first change rate based on the touch pressure;
• and
• a temperature calculator calculating a temperature value based on the change rate of the correction resistance value.
