Patent ID: 7187373

Claim:
An image display device comprising: a plurality of displaying pixel elements arranged in rows and columns; a plurality of gate lines, arranged corresponding to the respective display pixel rows, each connected to the displaying pixel elements on a corresponding row, for selecting the display pixels on the corresponding row when said each is selected; a plurality of data lines, arranged corresponding to the respective display pixel columns, each connected to the displaying pixel elements in a corresponding column, for transferring pixel data to the displaying pixel elements in the corresponding column; a peripheral control circuit responsive to an operation mode instructing signal for driving a selected gate line of said plurality of gate lines to a selected state to supply an accumulated charge of a corresponding display pixel onto a corresponding data line; and a plurality of amplifier circuits, arranged corresponding to the respective pixel columns, each for amplifying a voltage applied onto the data line in a corresponding column when activated, each amplifier circuit including a capacitance element, a differential amplifier circuit having a first input coupled to a corresponding data line and a second input connected to said capacitance element for differentially amplifying signals on the first and second input signals when made active, a first switching element coupling said first input to a reference power supply supplying a predetermined voltage in response to a first switch control signal, and a second switching element coupling an output of said differential amplifier circuit to said capacitance element in response to a second switch control signal.
