Abstract
An electro-optical device includes data lines divided into groups of M data lines, where N is a natural number equal to or greater than three. Output lines are arranged in correspondence with the data lines and receive, during a predetermined period, output of a correction voltage having a predetermined voltage level and sequential data voltages for defining gray scale levels of the pixels. A time division circuit simultaneously supplies the correction voltage output to the output line to M data lines of each group of data lines, where M is a natural number equal to or greater than two and equal to or less than “N−1”.
Claims8
An electro-optical device comprising:
- scanning lines;
- data lines divided into groups of data lines, each group of data lines including N data lines, N being a natural number equal to or greater than three;
- pixels arranged in correspondence with intersections of the scanning lines and the data lines;
- output lines arranged in correspondence with the data lines, the output lines receiving, during a predetermined period, output of a correction voltage having a predetermined voltage level and sequential data voltages for defining gray scale levels of the pixels;
- and
- a time division circuit that simultaneously supplies the correction voltage output to the output line to a sub-group of M, M being a natural number equal to or greater than two and equal to or less than “N−1”, data lines of each group of N data lines and that then simultaneously supplies the correction voltage output to the output line to a different sub-group of M data lines of each group of N data lines, the time division circuit performing a time division operation for the sequential data voltages output to the output line and distributing the data voltages which have been acquired by the time division operation to corresponding data lines in each group of data lines.
A method of driving an electro-optical device having scanning lines, data lines, pixels arranged in correspondence with intersections of the scanning lines and the data lines, and output lines arranged in correspondence with the data lines, the method comprising:
- outputting a correction voltage having a predetermined voltage level;
- simultaneously outputting the output correction voltage to a sub-group of M, M being a natural number equal to or greater than two and equal to or less than “N−1”, data lines from among data lines of one group including N, N being a natural number equal to or greater than three, data lines and then simultaneously outputting the output correction voltage to a different sub-group of M data lines from among data lines of one group including N;
- outputting sequential data voltages to the output lines after the correction voltage is output to the output lines;
- and
- performing a time division operation for the output sequential data voltages and distributing data voltages defining gray scale levels of the pixels, which have been acquired by the time division operation, to data lines in each group of data lines.
