Abstract:
1. An image display device comprising: a first DA converter which converts a first digital signal data to a first analog signal voltage; a second DA converter which converts a second digital signal data to a second analog signal voltage; a plurality of pixels arranged on an insulated substrate; analog selection switches; and signal wires which are connected to the pixels; wherein an amplitude range of the first analog signal voltage is different from an amplitude range of the second analog signal voltage; wherein each of the analog selection switches connects the second DA converter with one of the signal wires when the second analog voltage is between a first voltage and a second voltage or between a third voltage and a fourth voltage; wherein each of the analog selection switches connects the first DA converter with one of the signal wires when the first analog voltage is between the second voltage and the third voltage; and wherein the first DA converter is disposed on a substrate which is different from a substrate on which the second DA converter is disposed.
