Claim Text:
1. A display apparatus comprising: a touch panel configured to generate a current touch signal including a current touch position of a touch; an information processor configured to receive the current touch signal from the touch panel and a stored touch signal to compare the stored touch signal with the current touch signal to generate dynamic luminance information; a memory configured to receive the current touch signal from the information processor to store the current touch signal as the stored touch signal; and a display panel configured to receive the dynamic luminance information from the information processor and provide different amounts of power to pixels so as to display an image having different luminances in an emphasizing region corresponding to the current touch signal and the stored touch signal and a background region surrounding the emphasizing region, respectively, wherein the current touch signal further comprises touch time information, wherein the information processor is configured to compare touch time information of the stored touch signal with a reference transition time and a termination time to change a portion of the emphasizing region, which corresponds to a touch position of the stored touch signal, into a transition region when the touch time information exceeds the reference transition time, and wherein the information processor is further configured to change a portion of the transition region, which corresponds to the touch position of the stored touch signal, into the background region when the touch time information exceeds the termination time.
