Abstract
A liquid crystal display device includes a liquid crystal display panel, a backlight which illuminates the liquid crystal display panel, and a display control circuit which controls the liquid crystal display panel and the illumination light source. The display control circuit includes a panel driving section which drives the liquid crystal display panel after supply of power, a state detecting section which detects a display driving state that the panel driving section drives the liquid crystal display panel for display of a stable image corresponding to a video signal, and a light source driving section which drives the backlight in accordance with an illumination request signal, after detection of the display driving state by the state detecting section.
Claims4
A liquid crystal display device comprising:
- a liquid crystal display panel;
- an illumination light source which illuminates said liquid crystal display panel;
- and
- a display control circuit which controls said liquid crystal display panel and said illumination light source;
- wherein said display control circuit includes a panel driving section which drives said liquid crystal display panel after supply of power, a state detecting section which detects a display driving state that said panel driving section drives said liquid crystal display panel for display of a stable image corresponding to a video signal, and a light source driving section which drives said illumination light source in accordance with a request of illumination, after detection of the display driving state by said state detecting section,
- wherein said panel driving section is configured to be in a transfer driving state of transferring liquid crystal molecules from a splay alignment to a bend alignment upon supply of power in a case where said liquid crystal display panel is of an OCB mode, and in the display driving state subsequently to the transfer driving state.
