Problems solved by technology

At present, the commonly used method is to add a filter 185 on the inside or outside of the fluorescent wheel. Generally, it is designed as a circle of color wheel rings, which can only be designed according to the requirements of one color gamut. This kind of system can only emit one color. The primary color light required by the multi-color gamut cannot meet the multi-color gamut requirements, and the application limitations are relatively large

Abstract

The present invention provides a color wheel, including a substrate, and disposed on the substrate: a conversion layer, used to convert the wavelength of incident light to obtain received light; a first filter layer, used to perform wavelength conversion of the received light. filtering to obtain the first light for modulating the image in the first color gamut; and a second filter layer for filtering the light received to obtain the image for modulating the second color gamut the second light; wherein, the planes where the light-incident surface of the conversion layer, the light-incident surface of the first filter layer, and the light-incident surface of the second filter layer are respectively located are parallel to or coincident with each other. The invention also provides a light source system and a display device using the color wheel. The color wheel provided by the present invention can filter the received light to obtain the output of primary color light meeting the requirements of two color gamuts, so as to achieve different viewing effects and greatly enhance the user experience.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color wheel, a light source system and a display device. Background technique [0002] This section is intended to provide a background or context to a detailed description of the invention that is recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] see figure 1 , the laser fluorescent light source 100 in the prior art needs to produce red, green, blue or more colors of fluorescence, the usual method of use is to coat different phosphors on the color wheel, the excitation light source 110 generates excitation light, and irradiates the color wheel The conversion layer 183 provided with phosphor powder on the 180 excites the fluorescence, and the rotation of the driving motor produces the fluorescence of different colors emitted sequentially. Since the fluorescence spectrum is wide, its wavelength range will e...
