DEVICE AND METHOD FOR VARYING THE ROW SCANNING TIME TO COMPENSATE THE SIGNAL ATTENUATION DEPENDING ON THE DISTANCE BETWEEN PIXEL ROWS AND COLUMN DRIVER

摘要

A display device comprises a control circuit (50) for changing a time period of applying a signal voltage to each of the signal lines (42-1 to 42-n) and a scanning voltage to each of the scanning lines (41-1 to 41-m) within one vertical scanning period (T). The control circuit (50) controls each of horizontal scanning periods (t1 to tm) in such a manner that the period is gradually increased from the scanning line (41-m) located close to a vertical driving circuit (30) to the scanning line (41-1) located remote from the vertical driving circuit (30). In this way, when writing a signal voltage to a pixel via the signal lines, at each pixel the target potential is reached within the time period of applying the signal voltage.
