Abstract: 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.

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.
