Abstract

The display device drive unit includes a liquid crystal driver that generates a liquid crystal driving voltage for display device driving, and can operate in a master mode for outputting the foregoing voltage and in a slave mode for driving the display device in accordance with the liquid crystal driving voltage that has been inputted from the outside. The display device drive unit further includes a selection register for storing mode information that indicates whether the liquid crystal drivers is set to be in the master mode or the slave mode, and the liquid crystal driver outputs the liquid crystal voltage when the mode information indicative of the master mode is stored, and stops outputting the foregoing voltage when the mode information indicative of the slave mode is stored. Thus, it is not necessary to provide a setting terminal for switching between the master mode and the slave mode, and it is also possible to switch between both the modes after the drive unit has been packaged in the display device.
