Claim Text:
1. A display apparatus comprising: a display that displays a screen corresponding to a video signal, the display includes a plurality of pixels; a control unit configured to write the video signal into a memory at a predetermined writing speed according to a synchronization signal; a source driver configured to a capacitance type touch panel configured to be layered on the display and detect a touch operation, wherein the memory has a capacity which is smaller than the video signal of one frame, includes a write address and a read address, the addressing of which is formed in a ring shape, and independently writes and reads the video signal at different speeds, wherein the control unit controls the source driver to start reading the video signal when the video signal is written to fill a full capacity of the memory, allowing the touch panel to detect the touch operation in a blanking period, and wherein, when the capacity of the memory is 10% of the video signal of the single frame, the source driver reads the video signal which is written into the memory at a reading speed which is increased by 10% of the writing speed, and displays the video signal on the display.
