Patent ID: 7084847

Claim:
An image display apparatus comprising: image display means including a pixel in a region near an intersection at which each of signal lines and each of scanning lines are intersected with each other, said signal lines and said scanning lines being arranged in a matrix, and said pixel being connected to said signal line and said scanning line via a switch element; a group of gradation voltage lines to provide analogue gradation voltages in accordance with display gradations; decoder means for producing switch drive signals by which any one of said gradation voltage lines is selected in accordance with digital high-gradation image data; trigger signal output means for sequentially producing trigger signals in accordance with said image data; and a plurality of switch means, coupled to receive said switch drive signals and said trigger signals, for selecting a specified gradation voltage line in response to said switch drive signals under condition in which said trigger signals are inputted to said switch means, to supply a gradation voltage from said specified gradation voltage line to a specified signal line; wherein a plurality of switch drive lines for transmitting said switch drive signals are connected to said decoder means; a plurality of trigger lines for transmitting said trigger signals are connected to said trigger signal output means; output lines for transmitting said specified gradation voltage to said specified signal line are connected to said plurality of switch means; and said plurality of switch drive lines and said group of gradation voltage lines are arranged to intersect said plurality of trigger lines and said output lines.
