Embodiment Construction

[0044] Wide color gamut using the above light source (e.g., R, G, B three-color laser light source pure) may be implemented Rec.2020 standard color gamut, but high cost and other technical problems (such as red laser light and green laser expensive and relatively the electro-optical conversion efficiency low), the present invention provides a wide color gamut can be reduced using the light source apparatus and display method of a display. Typically, in a wide color gamut image data, each frame has a not very bright colors, in other words, only a part of image particularly green or bright colors in particular red, this time the need to provide a light source larger color gamut, when displaying another screen, a smaller color gamut can already cover all colors in the image, but this time using a relatively narrow color gamut of the light source in place of other wide color gamut light source ( a laser light source such as pure) as a light source of a display device, which saves the ...

Abstract

The invention relates to a display device and a display method. The display device includes a light source device, an image data processing module, and a light modulation device. The light source device is used to emit the first light and the second light. Compared with the second light, the first light has a narrower color gamut. The image data processing module receives the first image data, and the first image data includes each pixel of an image. The brightness data of the three primary colors based on the second light; when the image belongs to the narrow color gamut image, the image data processing module transmits the second image data to the light modulation device, wherein the second image data is each pixel of the image The brightness data of the three primary colors based on the second light is obtained by converting; when the image belongs to the wide color gamut image, the image data processing module transmits the first image data to the light modulation device, and the light modulation device transmits the first image data according to the first image data Modulating the second light or modulating the first light according to the second image data generates image light.

Description

Technical field [0001] The present invention relates to display technology, and particularly relates to an apparatus and a display method. Background technique [0002] Generally refers to the color gamut of the human eye to see the nature of the visible spectral locus, constituting the track of the visible spectrum is the area of ​​the region visible to the human eye can see a maximum color gamut. Currently, various display devices in the projector configuration, display or the like is employed involving pen R, G, B three-color display system, the image is reproduced color reproduction. In one specific color space, such as CIE1931x, y chromaticity space, a display device R, G, B three-color color gamut triangle formed by the apparatus can be referred to as a display area of ​​the larger color space, the people feel presented colors more vivid picture, more realistic, but this requires a display light source device capable of providing a greater color gamut. For example, a light ...
