摘要： A light diffuser containing light diffusing elements is arranged in the most appropriate position between a spatial light modulator and an illumination optical system. Thereby, particles as light diffusing elements diffuse rays of light emitted from a laser light source. Accordingly, indefinite numbers of speckle pattern are formed so that, for example, a speckle noise which occurs on an image projected to a screen is reduced. As a result, loss of light amount after light diffusion is suppressed to small amount, and thereby a laser image display apparatus capable of displaying a bright and high-quality image having no luminosity irregularity is provided.

摘要： An image display device and an image display system which can establish visible light communication without interfering with an image displayed at a predetermined frame rate are provided. A controller controls a spatial light modulator in accordance with an image signal to display the image, and also modulates an intensity of a visible light output from a backlight with a frequency higher than the frame rate of the image signal to have the visible light output from the backlight carry additional information. A light receiver receives the visible light and demodulates to extract the additional information. An additional information generator outputs the additional information.
