摘要： A touch sensor configured to be disposed in a liquid crystal display panel includes a plurality of x-axis read-out lines crossing and insulated from a plurality of y-axis read-out lines and a plurality of sensor units. Each sensor unit includes a reset unit, a capacitance detector, a first output unit, and a second output unit. The reset unit outputs a first reset signal based on a first control signal. The capacitance detector changes the first reset signal based on a variation of a cell gap of the liquid crystal display panel caused by a touch event. The first output unit changes an electric potential of a corresponding x-axis read-out line in response to the first reset signal changed in the capacitance detector. The second output unit changes an electric potential of a corresponding y-axis read-out line in response to the first reset signal changed in the capacitance detector.

摘要： Restoring an image is achieved by restoring a block by executing at least one first restoring function and at least one second restoring function. The first restoring function may be implemented using software, and the second restoring function may be implemented using hardware. By assigning restoring functions to be either first restoring functions or second restoring functions, even an image having high resolution can be restored and reproduced in real-time.
