| description | A display device in accordance with the present invention includes: a gate driver for carrying out display scanning on pixels sequentially in a first direction of a TFT liquid crystal panel so as to set pixels to display states thereof according to information to be displayed by the pixels in the TFT liquid crystal panel, the pixels being arranged in two dimensions and being individually controllable in terms of the display state through illumination; and a backlight unit for illuminating the individual pixels with intensity of light which increases and subsequently decreases in synchronism with the display scanning carried out by the gate driver, but only after the display scanning. The arrangement enables the backlight flashing period to be determined independently from a TFT panel scanning period or response time of liquid crystal, ensures an extended operating time of a TFT panel, effects a display period equal to, or longer than, the black blanking type, and achieves higher contrast than the black blanking type. |
