Abstract
An apparatus for driving a display panel comprises a receiving circuit of a TV broadcasting wave. The writing and reading operations of the pixel data to/from the memory are performed synchronously with the self-advancing clock signal, thereby preventing a disturbance of a display image upon channel switching. The display driving apparatus according to another aspect of the invention has two frame memories to alternately store pixel data and a memory control apparatus to control the writing and reading operations to/from the frame memories which makes a scanning line interpolation processing apparatus constructed by a memory, an arithmetic operating circuit, and the like unnecessary. Furthermore, the driving apparatus can be altered to allocate storage in a memory for pixels which are to be displayed in one picture plane. This storage allocation allows a motion image and the still image to be simultaneously displayed.
