Patent ID: 8289259

Claim:
A display device comprising: a display portion configured to be connected to a plurality of signal line groups; a signal driver configured to be connected to said plurality of signal line groups and output a plurality of video data groups to said plurality of signal line groups at timings respectively in a single horizontal period, each of said timings is shifted from an adjacent timing by a predetermined time; and a delay control circuit configured to vary said predetermined time every horizontal period and supply said predetermined time to said signal driver wherein said signal driver includes: a delay circuit configured to output said plurality of video data groups at said timings respectively in said single horizontal period, said each timing is shifted from an adjacent timing by said predetermined time, and a drive circuit configured to output said plurality of video data groups from said delay circuit to said plurality of signal line groups respectively in said single horizontal period, wherein said plurality of signal line groups is sorted into N (N is a integer, equal to or more than 2) groups, and is connected to said signal driver and said display portion as N sorted signal line groups, wherein said signal driver further includes: a division circuit configured to sort said plurality of video data groups into N groups to generate N sorted video data groups, wherein said delay circuit includes: N delay portions configured to output said N sorted video data groups at said timings respectively in said single horizontal period, said each timing is shifted from an adjacent timing by said predetermined time, and wherein said drive circuit outputs said N sorted video data groups from said N delay portions to said N sorted signal line groups respectively in said single horizontal period.
