Embodiment Construction
[0053] Based on the above, using a wide color gamut light source (such as R, G, B three-color pure laser light source) or a mixed light source with a wide color gamut light source and a fluorescent light source can make the display device achieve the color gamut standard of Rec.2020, but there are technologies such as high cost Problems (such as red laser and green laser are expensive and the electro-optical conversion efficiency is low), the present invention provides a display device and a display method that can reduce the use of wide color gamut light sources.
[0054] In one embodiment, the present invention proposes a method for dynamically enhancing the color gamut by adding laser light emitted by a wide-color gamut light source to the fluorescence, so that the display device can reach and exceed the DCI-P3 color gamut standard. while maintaining high efficiency. Furthermore, a scheme proposed by the present invention to dynamically adjust the brightness of the first li...

The invention relates to a display device and a display method. The display device includes a light source device, an image preprocessing controller and a light modulation device. The light source device emits first light and second light, and the color gamut of the second light is wider than that of the first light. The image preprocessing controller obtains the color gamut range of the image to be displayed and the brightness value of each pixel according to the original image data of the image to be displayed, and according to the color gamut range of the image to be displayed and the brightness value of each pixel value to determine the current color gamut range and control the light source device to emit the first light and second light corresponding to the amount of light required by the current color gamut range, and the light modulation device according to the current color gamut range corresponding The image data modulates the light emitted by the light source device to generate the image light of the image to be displayed, and the image data corresponding to the current color gamut range is used by the image preprocessing controller or the light modulation device according to the original image of the image to be displayed obtained through data conversion.
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 light sources of display devices such as laser projectors are generally divided into three categories. One is to excite phosphors of different colors by short-wavelength lasers to generate primary color light of the three primary colors of red, green, and blue. Another type directly uses red, green and blue three-color lasers as the three primary color light sources. The third type is a combination of the first two types. Generally, the blue laser light source is used as a short-wavelength excitation light source to excite phosphors to generate red and green primary color light, and it is also used as a blue primary color light. Each of the three different implementation techniques has advantages and disadvantages. For the scheme of laser excitation phosphor or laser fluorescence mixing, because t...
