Abstract

Disclosed is a drive circuit for an electro-optic device which includes a plurality of scan lines, a plurality of data lines, and a plurality of pixel circuits arranged corresponding to intersections between each of the scan lines and each of the data lines. The drive circuit includes a compensation voltage outputting circuit which, corresponding to a plurality of representative data lines selected out of the plurality of data lines, outputs compensation voltages which are obtained by compensating for differences in voltage characteristics among pixel circuits corresponding to the representative data lines; a reference voltage distributing circuit for outputting a plurality of reference voltages on the basis of at least two of the compensation voltages; and a data voltage outputting circuit for outputting data voltages based on the reference voltages respectively to the data lines.

Description

technical field [0001] The present invention relates to a drive circuit for an electro-optical device, the electro-optic device, an electronic device and a driving method for the electro-optic device. Background technique [0002] Heretofore, liquid crystal display devices have been known as examples of electro-optical devices. The liquid crystal display device includes a display unit, a drive circuit and an adjustment circuit. The display units are arranged at intersections between each of the plurality of scan lines and each of the plurality of data lines, so the display units are arranged in a matrix. Each display unit includes pixel circuits such as thin film transistors (hereinafter referred to as "TFTs") and display electrodes. The drive circuit supplies voltage to the TFT. An adjustment circuit is provided to each drive circuit, and adjusts the reference voltage according to the influence of the TFT and display electrode parasitic capacitance on the electrode volta...
