摘要： A control circuit changes the ratio of an illumination period to a non-illumination period in a frame period of a backlight according to a gradation level in the one frame period of an image displayed on a liquid crystal panel in such a manner that the higher the gradation level, the backlight illumination control circuit increases the ratio of the illumination period to the non-illumination period in the frame period of the backlight, and the lower the gradation level, the backlight illumination control circuit decreases the ratio of the illumination period to the non-illumination period in the frame period of the backlight and thereby controls illumination intensity toward the liquid crystal panel. A time center of illumination intensity in each one frame period of the backlight is controlled in order that the time center exists in a constant temporal position from the beginning of each frame period.

摘要： A backlight device includes a light diffusing member above a plurality of light sources that are partitioned into a plurality of illumination regions by a partition wall. A light incidence plane at which lights from the plurality of light sources enter is higher than the light sources and equal to or lower than a top of a partition wall. Moreover, a second light diffusing member is laminated above the light diffusing member so that a space is provided between the second light diffusing member and the first light diffusing member. The second light diffusing member has a light incidence plane in a position at a height that is higher than the top of the partition member. This makes it possible to independently control each of the illumination regions.

摘要： A backlight illumination control circuit changes the ratio of an illumination period BL to a non-illumination period in a frame period V of a backlight according to a gradation level in the one frame period V of an image displayed on a liquid crystal panel in such a manner that the higher the gradation level, the backlight illumination control circuit increases the ratio of the illumination period BL to the non-illumination period in the frame period V of the backlight, and the lower the gradation level, the backlight illumination control circuit decreases the ratio of the illumination period BL to the non-illumination period in the frame period V of the backlight and thereby controls illumination intensity toward the liquid crystal panel. A time center of illumination intensity in each one frame period V of the backlight is controlled in order that the time center exists in a constant temporal position T from the beginning of each frame period V. This realizes a liquid crystal display device being free from perceived flickers, giving a high contrast feeling, and being excellent in the performance of moving image display.

摘要： An illumination device for a flat panel display may include a light-guiding member for guiding light from a light-emitting lamp, wherein the light-emitting lamp has a light-emitting device incorporated in a lamp body, wherein the lamp body has a reflection surface that reflects light from the light-emitting device and an emitting surface that is opposite to the reflection surface and irradiates the reflected light from the reflection surface toward the light-guiding member. In certain example embodiments, the emitting surface is formed into a shape along the irradiated surface of the light-guiding member and the reflection surface is formed to be curved such that the reflected light is made approximately parallel seen from one direction upon reflecting the light from the light-emitting device.
