摘要： A projection apparatus includes at least one light source, a field lens, a light valve, and a projection lens. The light source provides an illumination beam. The field lens is disposed in a transmission path of the illumination beam including an effective beam passing through the field lens and a ghost beam reflected by the field lens. The effective beam forms a light spot on the light valve capable of converting the effective beam into an image beam. The projection lens is disposed in a transmission path of the image beam and a ghost beam path of the ghost beam. A center of the light spot does not overlap a center of the light valve. An offset direction from the light valve to an optical axis of the projection lens is the same as a direction from the center of the light valve to the center of the light spot.

摘要： The present invention provides a color wheel including a motor and a color filter module. The color filter module includes a first color filter having a first transmittance and a second color filter having a second transmittance that is smaller than the first transmittance. 50% of the first transmittance is corresponding to a first light wavelength and a second light wavelength that is larger than the first light wavelength. The second color filter and the first color filter have substantially same hues. 50% of the second transmittance is corresponding to a third light wavelength and a fourth light wavelength that is larger than the third light wavelength. The second color filter satisfies a first condition chosen from the third light wavelength being larger than the first light wavelength or the second light wavelength being larger than the fourth light wavelength.

摘要： An image display apparatus includes a screen, a reflection mirror, an adaptive optics, and a projection unit. The reflection mirror has a reflective surface facing a light incident surface of the screen, and is separated from the light incident surface by a space. The boundary of the space is defined by the edges of the reflective surface and the light incident surface. The adaptive optics is disposed on the boundary of the space. The projection unit is disposed outside the space. The adaptive optics has a light exit side facing the reflective surface of the reflection mirror, and a light incident side facing the projection unit. A projecting light is generated from the projection unit, passes through the adaptive optics for adjusting the image size formed by the projecting light, and then is projected to the reflective surface of the reflection mirror for being reflected to the light incident surface.
