ABSTRACT:
A display driving/controlling integrated circuit includes a display memory for storing data to be supplied to a display unit, a bus line of n-bit configuration for transmitting display data to be stored in the display memory, with n bits set as one unit, and a data array direction selection circuit connected to the bus line, for outputting display data on the bus line to the display memory with the bit array thereof kept in the original bit array status or outputting the display data to the display memory with the bit array thereof inverted with respect to the original bit array. There is provided means for writing display data with the bit array thereof inverted with respect to the original bit array when the display data is written into the display memory. Therefore, when the display panel is divided into upper and lower sections and driving LSIs have to be used for the upper and lower sections, wirings between the LSI output terminals and the display panel can be simplified and the wiring connections can be easily made.
