Patent ID: 6975290

Claim:
An active matrix type display apparatus comprising: a pixel unit formed by arranging a plurality of pixel circuits in a matrix manner, said pixel circuits each having an electrooptic device; data line driving means for supplying luminance data to said pixel circuits as a data line current via data lines; and current control means for dividing the data line current supplied from said data line driving means into a data current for writing the luminance data to each of said pixel circuits and a remaining bypass current; wherein said pixel circuit includes: a first analog switch having one terminal connected to said data line and controlled by a first scanning line; current-to-voltage conversion means connected to another terminal of said first analog switch, for converting the data current inputted via said first analog switch into a data voltage; a second analog switch having one terminal connected to an output terminal of said current-to-voltage conversion means and controlled by a second scanning line; data retaining means connected to another terminal of said second analog switch, for retaining the data voltage supplied from said current-to-voltage conversion means via said second analog switch; and driving means for driving said electrooptic device according to the data voltage retained by said data retaining means.
