Patent ID: 8199085

Claim:
A display apparatus comprising: a temperature sensor detecting a temperature; a first memory; a timing controller that receives an (n−1)th image signal and an nth image signal of consecutive frames, corrects the nth image signal and outputs a corrected signal of the nth image signal, wherein the timing controller generates a clock signal whose phase increases or decreases according to the detected temperature without changing a frequency of the clock signal, writes the nth image signal in the first memory in synchronization with the clock signal, reads the (n−1)th image signal from the first memory, and compares the nth image signal and the (n−1)th image signal with each other to correct the nth image signal based on the comparison result; a data driver that provides an image-data voltage corresponding to the corrected signal of the nth image signal; and a liquid crystal panel that displays an image corresponding to the image-data voltage.
