Abstract:
1. An illumination control device for illuminating a light modulation information display device with light, comprising: at least one illumination device for irradiating light which is generated through discharging, the at least one illumination device having a first portion and a second portion; and a driving waveform generation section for controlling the light which is irradiated from the at least one illumination device to the light modulation information display device, wherein: the light modulation information display device is operable so as to have a first period and a second period during which an image is displayed; during the first period, the driving waveform generation section applies a first voltage to the second portion of the at least one illumination device, the first voltage causing the second portion of the at least one illumination device to be turned entirely-ON; and during the second period, the driving waveform generation section applies a second voltage to the first portion of the at least one illumination device wherein the second voltage is different from the first voltage and the second voltage is a partially-ON voltage for causing the first portion of the at least one illumination device to be illuminated such that the at least one illumination device sustains a discharging state.
