    • A fixed pixel display device has a construction such that the leading-edge and trailing-edge waveforms of a voltage to be applied to a data electrode can be made steep. The fixed pixel display device is provided with scanning electrodes, data electrodes connected to actuation drivers (50), and light-emitting regions. The actuation drivers (50) each includes a switching circuit, an output circuit (51) and a subtraction circuit (52). The switching circuit is equipped with a first and switching circuits (53), (54) and a comparator 55. When a difference (Dm,n−Dm-1,n) between values of data for controlling states of light emission at light-emitting regions composed by the scanning electrodes in mth and (m−1)th rows is not smaller than a first reference value [not greater than a second reference value], the first switching circuit (53) [the second switching circuit (54)] is maintained in an ON state to apply a first voltage V1 [a second voltage V2] to the data electrode in an nth column. When the difference is smaller than the first reference value and is greater than the second reference value, the first and second switching circuits (53), (54) are maintained in OFF states, respectively.
    • 固定像素显示装置具有使得施加到数据电极的电压的前沿和后沿波形能够变得尖锐的结构。 固定像素显示装置设置有扫描电极,连接到致动驱动器(50)的数据电极和发光区域。 致动驱动器(50)各自包括开关电路,输出电路(51)和减法电路(52)。 开关电路配备有第一和开关电路(53),(54)和比较器55。 当用于控制由扫描电极构成的发光区域处的发光状态的数据的值之间的差(D m,n-D m-1,n n) 在第m和第(m-1)行中,第一开关电路(53)不小于第一参考值(不大于第二参考值) [第二开关电路(54)]保持在导通状态,以将第一电压V 1 [第二电压V 2>]施加到数据电极,其中n th 列。 当差小于第一参考值并且大于第二参考值时,第一和第二开关电路(53),(54)分别保持在OFF状态。
