DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME

摘要

A display apparatus includes a touch panel, an information processing unit, a storage unit, and a display panel. The touch panel generates a present touch signal including touch position information by a touch. The information processing unit receives the present touch signal from the touch panel and a stored touch signal from a storage unit, applies the present touch signal to the storage unit, and compares the stored touch signal with the present touch signal to generate dynamic luminance information. The storage unit stores the present touch signal. The display panel receives the dynamic luminance information from the information processing unit, and displays an image by distinguishing between an emphasis area corresponding to the present touch signal and the stored touch signal and a background area surrounding the emphasis area. Accordingly, power consumption can be reduced, and the visibility can be improved.
