Patent ID: 7379044

Claim:
An image display apparatus comprising: a plurality of pixels arranged in a matrix fashion on a substrate, each of said plurality of pixels being provided with a light emitting element with light intensity thereof varying with a current therethrough and a pixel circuit which drives said light emitting element; a plurality of analog signal lines disposed on said substrate which input an analog display voltage signal into each of said plurality of pixels; and a plurality of current-supply lines which supply a current to said light emitting element provided in each of said plurality of pixels. wherein: said pixel circuit provided in each of said plurality of pixels includes a first thin film transistor, a second thin film transistor, a first capacitor and a second capacitor; a drain electrode and a source electrode of said first thin film transistor are coupled to said light emitting element and a corresponding one of said plurality of current-supply lines, respectively; a drain electrode and a source electrode of said second thin film transistor are coupled to a gate electrode of said first thin film transistor and one of wiring lines disposed within said pixel circuit, respectively; one electrode of said first capacitor is coupled to said gate electrode of said first thin film transistor, and another electrode of said first capacitor is coupled to one of said wiring lines disposed within said pixel circuit; one electrode of said second capacitor is coupled to a gate electrode of said second thin film transistor, and another electrode of said second capacitor is coupled to a line supplied with a triangular waveform voltage during a specified portion of a frame period, said triangular waveform voltage increasing or decreasing at a uniform rate.
