Abstract
In a system including a color liquid crystal panel, a drive control device for driving the panel, and a microprocessor, the drive control device reduces the burden on the microprocessor as well as power consumption. In a liquid crystal display drive control device that incorporates a memory for storing image data displayed on a color liquid crystal panel, reads out the image data sequentially from the memory, generates image signals of the three primary colors for each pixel of the panel, and outputs the image signals from external output terminals, the drive control device includes a transparency arithmetic circuit that applies calculation processing to two image data read out from built-in memory and generates data for a transparent display, supplies display data generated by the transparency arithmetic circuit to a driver, and makes the driver generate and output drive signals to the liquid crystal panel.
