Patent ID: 8624816

Claim:
A liquid crystal display device, comprising: a display unit including a plurality of liquid crystal cells at crossing regions of a plurality of data lines and a plurality of gate lines; a source driver for supplying source voltages to the plurality of data lines; and a temperature sensor for sensing an ambient temperature and for outputting a temperature sensing signal corresponding to the ambient temperature, wherein the source driver comprises a source amplifying register unit for controlling a rising slope, over time, of the source voltages in accordance with the temperature sensing signal, wherein the source amplifying register unit comprises: an analog-digital converter for converting the temperature sensing signal to a digital sensing signal; a memory for storing a reference digital value corresponding to a reference temperature; a comparator for comparing the digital sensing signal with the reference digital value and for outputting a corresponding comparative value; and a controller for outputting a source amplifying set value in accordance with the comparative value, the source amplifying set value for controlling the rising slope of the source voltages.
