Abstract: A display driving device performs display drive based on display data with respect to a display unit including pixels arranged at respective intersections of data lines and scanning lines. The device includes: a current setting unit configured to store current gradation values which are set for the respective scanning lines that constitute a frame of the display data; a current gradation control unit configured to, at each of scan timings for the respective scanning lines within one frame, generate a constant current corresponding to a current gradation value for a corresponding scanning line among the current gradation values stored in the current setting unit; and a data line driving unit configured to supply the constant current generated by the current gradation control unit to the respective data lines for time periods corresponding to pixel gradation values defined by the display data.

Abstract: A display driving device performs display drive based on display data on a display unit in which data lines connected to a plurality of pixels arranged in a column direction and scanning lines connected to a plurality of pixels arranged in a row direction are disposed and in which the pixels are arranged at respective intersections of the data lines and the scanning lines. The display driving device includes a data line driving unit configured to supply a constant current to the data lines for time periods corresponding to gradation values of pixels specified by the display data whenever the scanning lines are selected. The data line driving unit drives the data lines such that the constant current is supplied to all or a part of pixels, of which gradation values specified by the display data indicate non-emission, for a non-emission time period.

Abstract: A scanning line driving device drives scanning lines in a display unit including data lines each connected to a plurality of pixels arranged in a column direction and the scanning lines each connected to a plurality of pixels arranged in a row direction, the pixels arranged at respective intersections of the data lines and the scanning lines. The device is configured to sequentially keep each of the scanning lines in a selected state pursuant to a predetermined order and output a scanning line drive signal, which is set to a low level in a high-luminance display drive and to a high level in a low-luminance display drive, to all the scanning lines during a blanking period between a period in which one scanning line is kept selected and a period in which a next scanning line is kept selected.
