Abstract
In one embodiment of the present invention, an active matrix display apparatus includes a screen having a plurality of regions each provided with a gate driver, in each of which plurality of regions scanning lines are driven so as to be sequentially selected by use of timing of a gate clock signal supplied to the gate driver, wherein corresponding ones of the gate clock signals for some of the plurality of regions have respective different pulse widths. Thus, it is possible to realize a display apparatus including a screen having a plurality of regions, in which display apparatus a difference in brightness between ones of some of the plurality of regions can be prevented.
Claims6
An active matrix display apparatus comprising:
- a screen having a plurality of regions each provided with a gate driver, in each of which plurality of regions scanning lines are driven so as to be sequentially selected by use of timing of a gate clock signal individually supplied to the gate driver, wherein:
- corresponding ones of the gate clock signals for some of the plurality of regions have respective different pulse widths, and
- the gate driver generates a scanning signal so that the scanning signal has a same period between pulse-start timing and pulse-end timing as a period of the gate clock signal between pulse-end timing of a pulse and pulse-start timing of a following pulse.
A method for driving an active matrix display apparatus including a screen having a plurality of regions each provided with a gate driver, the method comprising:
- driving scanning lines in each of the plurality of regions so that the scanning lines are sequentially selected by use of timing of a gate clock signal individually supplied to the gate driver, wherein:
- the scanning lines are driven in each of the plurality of regions so that corresponding ones of the gate clock signals for some of the plurality of regions have different pulse widths, and
- the gate driver generates a scanning signal so that the scanning signal has a same period between pulse-start timing and pulse-end timing as a period of the gate clock signal between pulse-end timing and pulse-start timing.
