Abstract: A touch panel comprises multiple first sensing electrodes constituting multiple rows, wherein the first sensing electrodes in each of the rows are electrically connected to each other, multiple second sensing electrodes constituting multiple columns crossing the rows, wherein the second sensing electrodes in each of the columns are electrically connected to each other, and multiple conductive patterns disposed between the first and second sensing electrodes. Each of the first and second sensing electrodes comprises multiple protrusions protruding outward from a corresponding boundary and multiple concave portions extending inward between the protrusions in a plan view. Pairs of protrusions extending from opposite sides of each of the first and second sensing electrodes are disposed opposite each other and are symmetrical to each other.

Abstract: An operation method of a display driver includes generating a count value by counting a period of a synchronization signal related to a synchronization packet received from a host, receiving a mode change command from the host, the mode change command indicating a change from a video mode transmitting first image data to a display by bypassing a frame memory to a command mode transmitting second image data to the display through the frame memory, and generating an internal synchronization signal having a period substantially equal to the period of the synchronization signal by using the count value based on the mode change command after a last pulse of the synchronization signal is generated. A time interval between the last pulse and a first pulse of the internal synchronization signal is equal to the period of the synchronization signal.
