DISPLAY DEVICE AND DRIVING METHOD THEREOF Russian patent published in 2011 - IPC G09G3/36 

FIELD: physics.

SUBSTANCE: liquid-crystal display device recognises every 12 video signal lines (SL1-SLn) in the order of their arrangement as a group and drives the video signal lines with time division in the group in the horizontal scanning period. The order of driving video signal lines in the group for a frame with an even number differs from the order for a frame with an odd number. For each line, the video signal line with an even number is driven first in one frame, and the video signal line with an odd number is driven first in another. The first and last driven video signal lines are specified so that they correspond to blue colour. The number of push-ups, under the effect of which video signal lines fall, is limited to two for the frame with an even number and zero for the frame with an odd number in addition to change of their order, so that the arising of vertical strips at low temperatures is prevented. Additionally, only video signal lines corresponding to the blue colour are specified as having insufficient charge, so that viewers find it difficult to recognise deterioration of image quality due to insufficient charge.

EFFECT: prevention of arising of vertical strips in display devices which perform driving with time division of video signal lines.
