Method for driving display panel
First Claim
1. A driving method for dividing each field of an input video signal into a plurality of subfields and driving a display panel for each of the plurality of subfields, so as to perform gradation display, said display panel having a plurality of pixel cells on each display line, wherein said method has, for each of said subfields:
- an address process in which a display data write scan is performed to set said pixel cells respectively in a light emitting mode or a non-light emitting mode by scanning said pixel cells for each at least one display line in accordance with display data based on the input video signal; and
a sustain process in which only said pixel cells that are set in the light emitting mode in the address process are caused to emit light, and wherein if the display data represents same data for a plurality of display lines, said display data write scan is performed simultaneously on the plurality of display lines in the address process.

Abstract
A driving method for a display panel which has, for each subfield, an address process in which a display data write scan is performed to set pixel cells respectively in a light emitting mode or a non-light emitting mode by scanning the pixel cells for each at least one display line, and a sustain process in which only the pixel cells that are set in the light emitting mode in the address process are caused to emit light. If display data represents same data for a plurality of display lines, the display data write scan is performed simultaneously on the plurality of display lines in the address process.

8. A driving method for dividing each field of an input video signal into a plurality of subfields and driving a display panel for each of the plurality of subfields, so as to perform gradation display, said display panel having a plurality of pixel cells on each display line,
wherein the method has, for each of said subfields: -
an address process in which a display data write scan by a selective erase address method is performed to set said pixel cells respectively in a light emitting mode or a non-light emitting mode by scanning said pixel cells for each display line in accordance with display data based on the input video signal; and
a sustain process in which only said pixel cells that are set in said light emitting mode are caused to emit light, and wherein, in the address process, the display data write scan is executed for display lines in which the display data indicates that a proportion having logical values which are equal to a predetermined value corresponding to the non-light emitting mode for said pixel cells on one display line is large, before the display data write scan is executed for the other display lines in which the display data indicates that the proportion is small.

9. A driving method for dividing each field of an input video signal into a plurality of subfields and driving a display panel for each of the plurality of subfields, so as to perform gradation display, said display panel having a plurality of pixel cells on each display line,
wherein the method has, for each of said subfields: -
an address process in which a display data write scan by a selective write address method is performed to set said pixel cells respectively in a light emitting mode or a non-light emitting mode by scanning said pixel cells for each display line in accordance with display data based on the input video signal; and
a sustain process in which only said pixel cells that are set in said light emitting mode are caused to emit light, and wherein, in the address process, the display data write scan is executed for display lines in which the display data indicates that a proportion having logical values which are equal to a predetermined value corresponding to the light emitting mode for said pixel cells on one display line is large, before the display data write scan is executed for the other display lines in which the display data indicates that the proportion is small.
