Document Type and Number:
Japanese Patent JP4996222
Kind Code:
B2
Abstract:
A display device in which a plurality of pixels are disposed in a matrix form includes data lines connected with the pixels, a signal controller for processing image data received from the outside and generating a plurality of control signals and clock signals, a gray voltage generator for generating a plurality of gray voltages, and a data driver including a plurality of data driver ICs for selecting gray voltages corresponding to image data from signal controller among the gray voltages and applying them as data voltages to data lines, wherein data driver includes four data driver ICs groups and each data driver IC group receives a separate clock signal and includes at least two data driver ICs connected in series with each other is disclosed. Because data driver IC groups receive the separate clock signals a signal delay can be reduced, and because phases of the clock signals are different a harmonic component can be reduced compared with the related art in which the clock signals have no phase difference, and thus EMI can be reduced.
