From a technical point of view, the currently popular monochromatic laser pointer light source on the market uses a blue laser as the core, cooperates with a fluorescent pink wheel to form white light, and then uses the color wheel to separate colors. The biggest disadvantage of this method is that the red and green colors are generated by the color wheel separation, so the monochromatic laser cannot always display the red and green images perfectly.
The red, green, and blue three-color laser light sources will have a higher level of color space than the monochromatic laser + phosphor. The three primary colors of red, green, and blue are complete, which can most realistically reproduce the rich and gorgeous colors of the objective world. Compared with the monochromatic light source, the two-color and three-color have a significant improvement in color performance, which can bring users the ultimate color experience.
At this exhibition, the three-color laser projector attracted enough attention. The author believes that the biggest disadvantage of tri-color lasers is the high cost. Ultra-high product prices are prohibitive for most consumers, so how to reduce costs as much as possible will be the focus of future tri-color laser efforts.
The appearance of the three-color laser projection is also a highlight of this exhibition. In addition to Christie and DP, the two traditional European and American brands, more local ethnic brands also displayed three-color laser pointer projection products at this exhibition.
