Abstract: A display apparatus and a display system are provided. The display apparatus includes: a narrow-spectrum light source configured to emit narrow-spectrum light in elliptical distribution; a reflection device including a reflection surface for reflecting the narrow-spectrum light to obtain to-be-modulated light; and a light modulation device configured to modulate the to-be-modulated light to obtain image light of an to-be-modulated image. The light modulation device includes a modulation surface configured to receive the to-be-modulated light, the modulating surface is at a preset angle to an optical axis of the to-be-modulated light such that the to-be-modulated light forms a circle light spot on the modulating surface. The narrow-spectrum light complying with the elliptical distribution is incident onto the light modulation device to form a circle light spot, thereby helping the light modulation device to emit image light in circular angular distribution, improving light effect and achieving better image display quality.

Abstract: A light source system includes an excitation light unit, a spectral filter unit, a scattering unit, and an excited-light unit. The excitation light unit is configured to emit excitation light. In an embodiment, the spectral filter unit reflects a portion of the excitation light to the scattering unit, the scattering unit scatters the same to generate a first light and a second light, and the spectral filter unit transmits the second light. The spectral filter unit also transmits another part of the excitation light to the excited-light unit, the excited-light unit emits excited light under the illumination thereof, and the spectral filter unit reflects the excited light, so that the spectral filter unit merges and emits the transmitted second light and the reflected excited light. The excitation light is thus split into two paths at the spectral filter unit, and finally emits light by combining excitation light and excited light.
