Patent ID: 7944414

Claim:
A display drive apparatus which drives a plurality of two-dimensionally arranged display pixels comprising a display panel based on display data, the display drive apparatus comprising: a selection circuit which sequentially sets the display pixels in each of a plurality of rows of the display panel in a selected state at every predetermined selection period including a first former period and a second later period, wherein the second later period of the selection period in one of the two adjacent rows of said plurality of the rows and the first former period in the other of the two adjacent rows are set as overlap periods which overlap with each other, and wherein the first former period of the selection period in one of the two adjacent rows of said plurality of the rows and the second later period in the other of the two adjacent rows are set as non-overlap periods which do not overlap with each other; a gradation signal generation circuit which generates a signal current as a gradation signal which controls a luminance gradation of each display pixel based on the display data, and which outputs the gradation signal corresponding to the pixels in each of a plurality of columns of the display panel in time-series at a timing corresponding to the first former period of the selected period in each row; and a current write circuit including a plurality of current holding/distributing circuits respectively provided to the columns of the display panel, each of which includes two latch sections for supplying a gradation current corresponding to the gradation signal in the selection period in each row, wherein each of the latch sections (i) in the first former period of the selection period in each row, supplies the gradation current to the corresponding display pixel, based on the gradation signal corresponding to one of two display pixels in one row of the display pixels in said two adjacent rows, of the gradation signals output by the gradation signal generation circuit, while fetching and holding said gradation signal corresponding to another one of two display pixels, and (ii) in the second later period of the selection period, supplies the gradation current to the corresponding display pixel in another row of said two adjacent rows, based on the gradation signal held in the first former period.
