  • Publication number: 20140176504
    Abstract: A display apparatus is disclosed. In one aspect the apparatus includes a touch panel, an information processor, a memory and a display panel. The touch panel generates a current touch signal including a current touch position of a touch. The information processor receives 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. The memory receives the current touch signal from the information processor to store the current touch signal as the stored touch signal. The display panel receives the dynamic luminance information from the information processor 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.
