Display apparatus and method of driving the same

A display apparatus comprising:

• a touch panel configured to generate a current touch signal having a touch position information 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 and the current touch signal, and generate dynamic luminance information and an image signal;
• a memory configured to receive the current touch signal from the information processor to store the current touch signal as the stored touch signal;
• a display panel configured to receive the image signal from the information processor to display an image;
• and
• a backlight assembly including a plurality of individually driving light sources, and configured to receive the dynamic luminance information from the information processor and provide different amounts of power to pixels so as to generate light having different luminances in an emphasizing region corresponding to the stored touch signal and a background region surrounding the emphasizing region,
• 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.

A method of driving a display apparatus including a display panel and a touch panel integrally formed with the display panel, the method comprising:

• detecting a current touch signal including touch position information;
• determining a current touch position as a portion of an emphasizing region when the touch position information of the current touch signal is not disposed in the emphasizing region;
• providing different amounts of power to pixels so as to display an image having an emphasizing luminance and a background luminance that is different from the emphasizing luminance in the emphasizing region and a background region that surrounds the emphasizing region, respectively, to dynamic individual control the display panel;
• storing the current touch signal to generate a stored touch signal, wherein the current touch signal further comprises touch time information;
• and
• comparing the touch time information of the stored touch signal 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.
