DRIVER CIRCUIT

摘要

A driver circuit driving a display device comprises: a gradation voltage generating circuit for generating m gradation voltages (m is an integer larger than or equal to 2) indicative of m stages of gradation levels; n decoder circuits each configured to select, out of the m gradation voltages, n drive voltages (n is an integer larger than or equal to 2) corresponding to n data pieces on the basis of n input gradation signals; m gradation voltage wirings each for transferring the m gradation voltages to the n decoder circuits, respectively; and a charge supplementing circuit for supplementing each of the m gradation voltage wirings with an amount of electric charge when a voltage drop occurs in the gradation voltage wirings.

1. A driver circuit driving a display device comprising:
a gradation voltage generating circuit for generating m gradation voltages (m is an integer larger than or equal to 2) indicative of m stages of gradation levels; n decoder circuits (n is an integer larger than or equal to 2) each for selecting and outputting, out of the m gradation voltages, n drive voltages corresponding to n data pieces on the basis of n input gradation signals; m gradation voltage wirings each for transferring the m gradation voltages to said n decoder circuits, respectively; and a charge supplementing circuit for supplementing, if a voltage drop occurs in any one or more of the m gradation voltage wirings, said any one or more of the m gradation voltage wirings with an amount of electric charge.
