Abstract: Provided are a lens adjusting device and a projection apparatus. The device includes a first adjusting support including a lens support, a first guide post and a second guide post; and a second adjusting support including a moving support, a first limit slot, and a first boss. The first guide post is fixedly clamped in the first limit slot, the second guide post being connected to the first boss, and the lens support being supported by and slidably connected to the first guide post and second guide post, such that the lens support is slidable relative to the second adjusting support along the first direction. The lens support is configured to adjust a position of the second guide post relative to the first boss prior to the second guide post and the first boss being fastened to each other to parallel the second guide post and the first guide post.

Abstract: A system and method for dynamically adjusting a color gamut of a display system, and a display system are provided. The display system includes a light source system and an imaging system. The light source system includes an excitation light source and a narrow-spectrum primary-light source. The imaging system includes a spatial light modulation device and the system for dynamically adjusting the color gamut of the display system. The excitation light source emits excitation light which is processed to output at least one broad-spectrum primary light. The narrow-spectrum primary light source outputs at least one narrow-spectrum primary light. The narrow-spectrum primary light and the wide-spectrum primary light are combined and then output to the imaging system. The brightness of light emitted by the excitation light source and the narrow-spectrum primary light source is adjusted. Therefore, the efficiency is improved and the costs are reduced while enhancing the color gamut.
