Abstract: Disclosed are a wavelength conversion device, a light-emitting device and a projection system, comprising a wavelength conversion layer having a first surface and a second surface opposite each other. The first surface receives an excitation light. The wavelength conversion layer absorbs the excitation to produce a converted light and emits the converted light or the mixture of the converted light and the excitation light from the first surface and the second surface. A scattering reflective substrate is stacked with the wavelength conversion layer and includes a white porous ceramic or a white scattering material for scattering the incident light. The scattering reflective substrate includes a third surface facing the second surface and scatters at least a part of the incident light on the third surface and then emits all the light from the third surface to the second surface.

Abstract: A projection screen includes an optical collimating layer and a surface diffusion layer which are arranged in sequence. A grating absorption layer for absorbing ambient light from various directions except a projection light direction is also provided between the optical collimating layer and the surface diffusion layer. The grating absorption layer includes a plurality of light-absorption ring-shaped units with different radii. The plurality of light-absorption ring-shaped units are arranged in a concentric ring. Each of the light-absorption ring-shaped units consists of a plurality of gratings arranged in the circumferential direction of the concentric ring. By taking a vertical symmetrical center line of the projection screen as a center, in a direction extending along the circumferential direction of the concentric ring to the left side and the right side of the projection screen, the distance between two adjacent gratings in the same light-absorption ring-shaped unit gradually increases.
