FIELD: information technology.
SUBSTANCE: display has a display unit with scanning signal lines which are divided into a plurality of groups (Gr1, Gr2, …) which are successively selected. When successive scanning is carried out in scanning signal lines belonging to a selected group, signal potentials of the same polarity are successively transmitted to a data signal line. The polarity of the signal potential is inverted between a preceding group and the next group selected continuously. A plurality (n) of idle scanning periods (periods Da, Db, …) are entered between a horizontal scanning period, which corresponds to the last horizontal scanning in the preceding group, and the horizontal scanning period corresponding to the first horizontal scanning in the next group. In each of the idle scanning periods, one of the scanning signal lines belonging to a group selected after the preceding group undergoes idle scanning so that this scanning signal line is maintained in driven state for a given period of time, and then disconnected to match the loaded state of the driving circuit of scanning signal lines.
EFFECT: suppressing non-uniformities in form of horizontal strips on the display which uses block inversion control.
