Embodiment approach 1
[0071] Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 10 .
[0072] First, a projection display device (display device) according to Embodiment 1 of the present invention will be described with reference to FIG. 1 . The projection type display device of this embodiment is a projection type color display device that modulates light emitted from a light source by a liquid crystal light valve to display a color image.
[0073] FIG. 1 shows the outline of a projection display device according to this embodiment.
[0074] The projection display device, as shown in Figure 1, is a liquid crystal light that adjusts the light of each color of R, G, B, and W by an illumination device 1 that emits each color light of R, G, B, and W (white) in time sequence. A valve (light modulation device, liquid crystal panel) 40 and a projection lens 70 for projecting modulated light are schematically configured.

Embodiment approach 2
[0127] Second, refer to Figure 11 to Figure 15 Embodiment 2 of the present invention will be described.
[0128] The configuration of the projection display device of the present embodiment is the same as that of the first embodiment, but the driving method is different from the first embodiment. Therefore, in this embodiment, using FIG. 11 and Figure 15 Only the driving method of the projection display device will be described, and the description of the configuration of the projection display device will be omitted.
[0129] FIG. 11 is a block diagram showing the configuration of a drive circuit of the projection display device according to the present embodiment.
[0130] A driving method of the projection display device according to this embodiment will be described.
[0131] In the present embodiment, as shown in FIG. 11 , image signals corresponding to the colors R, G, and B are input to the control unit 81A in parallel, and timing signals are input to the control u...

Abstract
Aspects of the invention can provide a display device, a display method, and a projection type display device that allow a characteristic of a display image such as brightness to be continuously changed. The display device can include a light source capable of emitting a plurality of different color lights and a white light, and an optical modulation device for modulating light corresponding to the lights emitted from the light source. The ratio of the period of emitting the white light relative to the total of the periods of emitting the lights from the light source can be variable.
Description
technical field [0001] The present invention relates to a display device, a display method and a projection display device. Background technique [0002] In recent years, information equipment has been rapidly advanced, and demands for high-resolution, low-power consumption, and thin image display devices have increased, and research and development have been actively carried out. Among them, a liquid crystal display device is expected to be a display device capable of electrically controlling the arrangement of liquid crystal molecules and changing optical characteristics, thereby meeting the above-mentioned needs. As one form of such a liquid crystal display device, there is known a projection type liquid crystal display device (liquid crystalprojector) that enlarges and projects a display image emitted from an optical system using a liquid crystal light valve onto a screen by means of a projection lens. [0003] Projection-type liquid crystal display devices include a s...
