Title: LIGHT SOURCE SYSTEM AND DISPLAY DEVICE
Abstract:
A light source system (10), comprising: a light source device (100), a first light splitting and combining device (104), a wavelength converter (107) and a light processing device (106). The light source device (100) issues first excitation light and second excitation light, the first excitation light having a first polarization state, and the second excitation light having a second polarization state that is different from first polarization state. The first light splitting and combining device (104) comprises at least one transparent substrate (104a), wherein the at least one transparent substrate (104a) guides excitation light in a first preset proportion among the second excitation light to one of the light processing device (106) and the wavelength converter (107), and guides another part of the excitation light among the second excitation light and the first excitation light to the other one of the light processing apparatus (106) and the wavelength converter (107), the first preset proportion corresponding to the number of the transparent substrates. The light processing device (106) scatters the received excitation light and emits third excitation light. The wavelength converter (107) converts the received excitation light into excited light. The third excitation light and the excited light are guided to a light-emitting channel.
