Abstract
A flat-panel display device includes a display control unit having a scanning line driver for periodically selecting at least two adjacent scanning lines and driving such lines together. A scanning controller controls a driver to turn on elements connected to a first one of the adjacent scanning lines located on one side of a row of the pixels capacitively coupled thereto and driven for the row of pixels, and elements connected to a second one of the adjacent scanning lines located on another side of the row of pixels capacitively coupled thereto and not driven for the row of pixels, at a substantially identical timing, and to turn off the elements connected to second adjacent scanning line earlier than the elements connected to the first adjacent scanning line.
Claims11
A flat-panel display device comprising:
- a plurality of display pixels arranged in a matrix;
- a plurality of scanning lines formed along rows of the display pixels;
- a plurality of signal lines formed along columns of the display pixels;
- a plurality of switching elements formed in the vicinity of intersections between the scanning lines and the signal lines and each driven via a corresponding scanning line to apply a potential of the corresponding signal line to a corresponding display pixel;
- and
- a display control unit for driving the scanning lines and the signal lines;
- wherein said display control unit includes:
- a scanning line driver for periodically selecting at least two adjacent scanning lines from the plurality of scanning lines to drive the adjacent scanning lines together;
- and
- a scanning controller for controlling said scanning line driver to turn on the switching elements connected to a first one of the adjacent scanning lines which is located on one side of a row of the display pixels capacitively coupled thereto and driven for the row of display pixels, and the switching elements connected to a second one of the adjacent scanning lines which is located on another side of the row of display pixels capacitively coupled thereto and not driven for the row of display pixels, at a substantially identical timing, and to turn off the switching elements connected to the second adjacent scanning line at an earlier timing than that for the switching elements connected to the first adjacent scanning line by a predetermined period.

A display control method for a display panel which includes
- a plurality of display pixels arranged in a matrix, a plurality of scanning lines formed along rows of the display pixels, a plurality of signal lines formed along columns of the display pixels, and a plurality of switching elements formed in the vicinity of intersections between the scanning lines and the signal lines and each driven via a corresponding scanning line to apply a potential of the corresponding signal line to a corresponding display pixel, said apparatus comprising:
- the steps of
- periodically selecting at least two adjacent scanning lines from the plurality of scanning lines to drive the adjacent scanning lines together;
- and
- performing a control of turning on the switching elements connected to a first one of the adjacent scanning lines which is located on one side of a row of the display pixels capacitively coupled thereto and driven for the row of display pixels, and the switching elements connected to a second one of the adjacent scanning lines which is located on another side of the row of display pixels capacitively coupled thereto and not driven for the row of display pixels, at a substantially identical timing, and of turning off the switching elements connected to the second adjacent scanning line at an earlier timing than that for the switching elements connected to the first adjacent scanning line by a predetermined period.
