Abstract:
A liquid crystal display device includes an upper substrate, a lower substrate including a data line and a gate line insulated from the data line, a liquid crystal layer between the lower substrate and the upper substrate, a current sensing unit which detects a data current based on a data signal applied to the data line so as to detect a change in a liquid crystal capacitance of the liquid crystal layer, a rectifying amplifier which rectifies or amplifies the detected data current so as to generate and output a rectified signal, a pulse generator which generates a sensing pulse by comparing the rectified signal with a reference voltage, and a duty width detector which detects a duty width of the sensing pulse generated by the pulse generator where the reference voltage is set based on a voltage difference between data signals successively applied to the data line.

Claim (Index 12):
A liquid crystal display device comprising:\n a display panel; a pixel on the display panel, the pixel comprising a liquid crystal layer having a liquid crystal capacitance which varies depending on a temperature change; a data driver which applies a data signal to the pixel and a gate driver which applies a gate signal to the pixel; a timing controller which controls the data driver and the gate driver; and a temperature sensor which detects a temperature of the liquid crystal layer, and comprises:\n a current sensing unit which detects a data current generated by the data signal; \n a rectifying amplifier which rectifies or amplifies the detected data current so as to output a rectified signal; \n a reference voltage conversion unit which sets a reference voltage based on a voltage difference between data signals successively applied to the data line; \n a pulse generator which compares the rectified signal with the reference voltage so as to generate a sensing pulse; \n a duty width detector which detects a duty width of the sensing pulse output from the pulse generator; and \n a temperature calculator which determines the temperature of the liquid crystal layer based on the duty width, \n wherein the timing controller corrects an input image data based on the temperature of the liquid crystal layer output from the temperature sensor.
