摘要： An optical engine module, configured to receive an illumination light beam, includes a light valve module, an optical prism, and a first connecting layer. The optical prism is disposed on a transmission path of the illumination light beam and configured to guide the illumination light beam to the light valve module and to guide an image light beam from the light valve module. The light valve module is disposed on the transmission path of the illumination light beam from the optical prism and configured to convert the illumination light beam into the image light beam. The first connecting layer is disposed between the light valve module and the optical prism. The image light beam from the light valve module sequentially passes through the first connecting layer and the optical prism to transmit in a direction. There is no air gap between the optical prism and the light valve module.

摘要： The invention provides a display device including a display panel and a backlight module including a light guide plate, a light source, and an optical film. The light guide plate has light incident and exit surfaces. The light source is disposed at one side of the light incident surface. The optical film is overlapped with the light exit surface, and has first optical microstructures facing the light exit surface. The display panel includes a liquid crystal cell overlapped with the light exit surface, first and second polarizers respectively disposed at two opposite sides of the liquid crystal cell, and a phase retardation film disposed between the first and second polarizers. The first polarizer is located between the liquid crystal cell and the optical film.

摘要： A projection device includes a housing, a rotating component, and a foot pad component. The housing has the first and second parts. The second part has a screw hole. The rotating component has an abutting part and a driving part. The abutting part passes through and abuts against the first part. The foot pad component has a foot pad part, a screw rod part, and a driven-to-move part. The screw rod part is connected between the foot pad part and the driven-to-move part and screwed to the second part through the screw hole. The driven-to-move part is in the housing and embedded in the driving part. The rotating component rotates relative to the first part, causing the foot pad component to be driven by the rotating component to rotate relative to the second part, thereby changing a height of the housing relative to the foot pad part.
