Abstract
A driving display device includes a gray scale voltage generating circuit for generating a plurality of levels of gray scale voltages from a reference voltage, an amplitude adjustment register capable of setting the amplitude of a characteristic curve of a plurality of levels of the gray scale voltages with respect to gray scale numbers, and a gradient adjustment register capable of setting the gradient of the characteristic curve. With this arrangement, the gradient and amplitude of the gray scale number-gray scale voltage characteristic are adjusted.
