Patent ID: 7123247

Claim:
A display control circuit which controls display of an electro-optical device having pixels specified by 1st to N-th scan lines (N is a natural number) and 1st to M-th signal lines (M is a natural number) intersecting each other, the display control circuit comprising: an area-block-display control data storing section which stores area-block-display control data used to set a display area or a non-display area in units of area blocks each of which includes a plurality of the signal lines and a plurality of the scan lines; a controller which: sets the display area or the non-display area in units of the area blocks on the basis of the area-block-display control data, for a scan drive circuit which sequentially performs scan-driving of at least part of the 1st to N-th scan lines corresponding to the display area; and which sets the display area or the non-display area in units of the area blocks on the basis of the area-block-display control data, for a signal drive circuit which drives at least part of the 1st to M-th signal lines corresponding to the display area; a band-partial-display control data holding section which holds band-partial-display control data used to set the display area or the non-display area in units of line blocks each of which includes a plurality of the scan lines; and a mode switching section which performs switching between a first mode and a second mode; wherein the display area or the non-display area is specified in units of the area blocks for the scan drive circuit and the signal drive circuit on the basis of the area-block-display control data, in the first mode; and wherein the display area or the non-display area is specified in units of the line blocks for only the scan drive circuit of the scan drive circuit and the signal drive circuit on the basis of the band-partial-display control data, in the second mode.
