Abstract:
1. A fixed pixel display device provided with a multiple number M (M≧2) of stripe-shaped scanning electrodes extending in a first direction and another multiple number N(N≧2) of stripe-shaped data electrodes extending in a second direction different from said first direction such that light-emitting regions formed of overlap regions of said scanning electrodes and said data electrodes are arrayed in a two-dimensional matrix form of M rows×N columns, wherein: said fixed pixel display device is provided with actuation drivers connected to the respective data electrodes to actuate said data electrodes; each said actuation driver comprises a switching circuit, an output circuit, and a subtraction circuit; said switching circuit is provided with: (A) a first switching circuit for applying a first voltage V (B) a second switching circuit for applying a second voltage V (C) a comparator for performing on/off control of said first switching circuit and second switching circuit; a voltage, outputted from said output circuit on a basis of a value D a value (D (1) when said input value is not smaller than said first reference value, said first switching circuit is maintained in an ON state for a predetermined duration shorter than said fixed duration on a basis of an output from said comparator such that during said predetermined duration, a first voltage V (2) when said input value is not greater than said second reference value, said second switching circuit is maintained in an ON state for a predetermined duration shorter than said fixed duration on a basis of said output from said comparator such that during said predetermined duration, a second voltage V (3) when said input value is smaller than said first reference value but is greater than said second reference value, said first switching circuit and said second switching circuit are maintained in OFF-states, respectively.
