Embodiment Construction

[0044] Based on the above, using a wide color gamut light source (such as R, G, B three-color pure laser light source) can achieve the color gamut standard of Rec.2020, but there are technical problems such as high cost (such as red laser and green laser are expensive and the electro-optic conversion efficiency is low. low), the present invention provides a display device and a display method that can reduce the use of wide color gamut light sources. Usually, in a wide color gamut image data, not every frame of image has a very bright color, in other words, only a part of the image has a particularly green or red bright color, which requires the light source to provide Larger color gamut area, and when displaying other pictures, a smaller color gamut area can already cover all the colors in the image, and this period uses other light sources with relatively narrow color gamuts to replace wide color gamut light sources ( Such as pure laser light source) as the light source of t...

Abstract

The invention relates to display equipment and a display method. The display equipment includes a light source device, an image data processing module, and a light modulating device. The light sourcedevice is used for emitting first light and second light; the first light has narrower gamut than the second light; the image data processing module receives first image data that includes trichromatic brightness data, based on the second light, of pixels of an image; when the image is a narrow gamut image, the image data processing module transmits second image data to the light modulating device, wherein the second image data is acquired by converting the trichromatic brightness data, based on the second light, of the pixels of the image; when the image is a wide gamut image, the image dataprocessing module transmits the first image data to the light modulating device; the light modulating device modulates the second light according to the first image data or modulates the first light according to the second image data, in order to generate image light.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method. Background technique [0002] The color gamut usually refers to the spectral trajectory of visible light that the human eye can see in nature, and the area formed by the visible spectral trajectory is the largest color gamut area that the human eye can see visible light. At present, projectors, monitors, etc., which are composed of different display devices, all use R, G, and B three primary color display systems to reproduce the color of the image. In a specified chromaticity space, such as CIE1931x, y chromaticity space, the triangle formed by the three primary colors of R, G, and B of the display device is called the color gamut that the device can display. The brighter and more realistic the color picture, but this requires the light source of the display device to provide a larger color gamut. For example, the color gamut sta...
