摘要： An apparatus for driving a display panel includes a first memory which stores a frame image data, a second memory which stores overshooting information. The apparatus receives an image signal from an external system via a CPU interface process. The second memory stores a difference data between the frame image data and an overshooting data. The overshoot is then calculated from the difference data and the frame image data. The apparatus also includes a two-line memory which stores an image signal of an n-th frame in a line unit and an image signal of an n−1-th frame in another line. The two-line memory compares the consecutive two frame data, so that the apparatus extracts overshooting information from a look up table.

摘要： A display panel includes an array substrate, an opposite substrate and a liquid crystal layer disposed between the array substrate and the opposite substrate. A sensing array outputs an initial voltage in response to an initial thickness of the liquid crystal layer during an initializing time and a sensing voltage in response to a varied thickness of the liquid crystal layer due to external force during a sensing time. A control part compares the sensing voltage with the initial voltage, determines whether the external force is applied to the display panel, and generates information indicating a position to which the external force is applied. Thus, the display apparatus may improve sensing ability to an external signal inputted through the display panel thereof.
