An organic electro-luminescence display device includes: a first substrate having transmissive properties; a touch electrode for a touch sensor, the touch electrode being provided on a main surface of the first substrate; an insulating film provided on the main surface and covering the touch electrode wherein the insulating film includes a first surface at the touch electrode-side and a second surface opposite to the first surface; an organic light-emitting element provided on the second surface of the insulating film; a second substrate provided facing the main surface of the first substrate; and an integrated circuit electrically connected with both the touch electrode and the organic light-emitting element. The touch electrode, the insulating film, and the organic light-emitting element are interposed between the first substrate and the second substrate.

Organic EL display device

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.

Display driving method to drive a display based on display data with respect to a display unit including pixel arranged at data and scan line intersections, and corresponding display driving device and display apparatus

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.
