Abstract
A field sequential driving method for driving a liquid crystal display, wherein said liquid crystal includes a plurality of gate lines, comprising the steps of: grouping said gate lines into a plurality of zone, including a first zone to an Nth zone; sequentially addressing the first zone to the Nth zone, wherein addresses each zone comprising: writing black signals into pixels in the zone; writing white signals into pixels in the zone after the black signals are written into pixels in the zone; sequentially writing color signals to corresponding pixel in the zone; and sequentially flashing light source from the first zone to the Nth zone.

A field sequential driving method for driving a liquid crystal display, wherein said liquid crystal includes a plurality of gate lines, comprising the steps of:
- grouping said gate lines into a plurality of pixel zones, including a first pixel zone to an Nth pixel zone;
- sequentially addressing the first pixel zone to the Nth pixel zone, wherein addressing each pixel zone comprises:
- writing black signals into pixels in the pixel zone;
- writing white signals into pixels in the pixel zone after the black signals are written into pixels in the pixel zone;
- sequentially writing color signals to corresponding pixels in the pixel zone after the white signals are written into pixels in the pixel zone;
- and
- sequentially flashing light source from the first pixel zone to the Nth pixel zone.
A field sequential driving method for driving a liquid crystal display, comprising the steps of:
- dividing a plurality of gate lines, driving a plurality of pixels, into a first pixel zone and a second pixel zone;
- writing first black signals into a part of the pixels in the first pixel zone;
- writing first white signals into the first pixel zone after the black signals are written into the first pixel zone;
- sequentially writing color signals corresponding to each pixel after writing the first white signals, only in first pixel zone ,driven by each gate line respectively;
- writing second black signals into second pixel zone after color signals are written;
- writing second white signals into another part of the pixels in the second pixel zone after second black signals are written;
- sequentially writing another synchronized color signals corresponding to each pixel after writing the second white signals, only in another pixel zone ,driven by each gate line respectively;
- sequentially and periodically turning on a plurality of independent first light sources in the first pixel zone;
- and
- sequentially and periodically turning on a plurality of independent second light sources in the second pixel zone.
