LIGHT SOURCE SYSTEM AND DISPLAY DEVICE

WIPO Patent Application WO/2021/008332

A1

A light source system (100) and a display device (10). The light source system (100) comprises: an excitation light source (110) used for emitting excitation light (a); a wavelength conversion device (180) provided with a conversion region (Y) and a reflection region (B), the conversion region (Y) and the reflection region (B) being located on different planes, the timing being on a light path of the excitation light (a), the conversion region (Y) being used to convert at least part of the excitation light (a) into excited light (b1), and the reflection region (B) being used to reflect the excitation light (a); a collection lens group (170) that is used for guiding light emitted from the conversion region (Y) to be transmitted along a first direction to obtain first light (b), and that is used for guiding the excitation light (a) emitted from the reflection region (B) to be transmitted along a second direction to obtain second light (c); a first guiding device (130) used for guiding the excited light (b1) in the first light (b) to be emitted along a first optical path (L1); and a second guiding device (150) used for guiding the second light (c) to be transmitted along a second optical path (L2). The first guiding device (130) is further used to combine the excited light (b1) transmitted along the first optical path (L1) and the second light (c) transmitted along the second optical path (L2).
