Title: LIGHT-SOURCE SYSTEM AND DISPLAY DEVICE
Abstract:
A light source system (200), comprising an excitation light source (201), a scattering device (207), a wavelength conversion device (209), a light splitting/converging device (205) and a relay lens (210). The light splitting/converging device (205) is used to guide a first part of excitation light sent from the excitation light source (201) to the scattering device (207) and to guide a second part of excitation light sent from the excitation light source (201) to the wavelength conversion device (209); the scattering device (207) is used to scatter the first part of the excitation light and then supply to the light splitting/converging device (205); the light splitting/converging device (205) is also used to guide the scattered first part of the excitation light to a light exiting channel; the wavelength conversion device (209) is used to convert the second part of the excitation light to an excited light which is then supplied to the light splitting/converging device (205); the light splitting/converging device (205) is also used to guide the excited light to the light exiting channel; the relay lens (210) is provided inside the light exiting channel, and is used to focus the scattered first part of the excitation light and the excited light sent by the light splitting/converging device (205). Also provided is a display device.
