Abstract: A touch projection system includes a screen, an image-capturing device, a micromirror device, and a TIR prism disposed in front of the micromirror device. The TIR prism includes an optical path compensation structure or a hollowed channel, so that an image light from the screen, traveling through the TIR prism to be reflected by the micromirror device, can travel through the optical path compensation structure or the hollowed channel to avoid a probable optical path difference on the image light due to traveling through the TIR prism. Thereby, the invention can solve that a distortion may be induced in a touch image formed by the image-capturing device receiving the image light reflected by the micromirror device.

Abstract: A projector includes a color wheel module and an optical engine. The color wheel module includes a rotation device, a mount, a color wheel, and an optical sensor. The color wheel is fixed on a rotary part of the rotation device. The rotation device and the optical sensor are fixed on the mount. The mount has an anti-dust structure includes a curved surface that is opposite to a rotary surface of the rotary part and extends in a rotation direction of the rotary part. The curved surface and the optical sensor are arranged sequentially in the rotation direction. Either by shortening a distance between the curved surface and the rotary surface or by a guiding slot that is disposed beside or lower than the curved surface, dust deposited on the optical sensor can be reduced effectively.

Abstract: An optical module includes a light source, a phosphor wheel, a first driving unit, a color wheel, a second driving unit, a third driving unit and a control unit. The phosphor wheel includes a phosphor area. The color wheel includes a plurality of sector-shaped filters. At least one of the sector-shaped filters includes a plurality of filter areas. Central angles of the filter areas are identical. Colors of at least two adjacent filter areas are different. The control unit selectively controls one of the first driving unit and the second driving unit by a delay time to control an overlap ratio between the phosphor area and one of the filter areas. The control unit selectively controls the third driving unit to drive the color wheel to move with respect to the phosphor wheel, so as to move one of the filter areas to a position corresponding to the phosphor area.

Abstract: A projector includes a projection lens, an optical engine, and a light device. The light device has a lighting axis and includes a movable frame, two light sources fixedly disposed on the movable frame, and a driving part kinematically connected with the movable frame. The driving part is disposed in front of the two light sources. The driving part moves the movable frame such that the two light sources moves simultaneously so as to selectively make one of the two light sources emit light along the lighting axis, which avoids single light source operating for long time. The optical engine is disposed close to the light device and has a light entrance axis. The light entrance axis coincides with the lighting axis. The optical engine includes a digital micromirror device that modulates light from the light device to be projected out the projector through the projection lens.

Abstract: A projector includes a holding casing having a hole structure, a projection lens movably disposed through the hole structure, a containing casing detachably fixed to the holding casing for forming a containing space, an image projection module disposed in the containing space, and a flexible washer. A first engaging structure is formed on an external surface of the projection lens. The flexible washer jackets the projection lens and has first and second ring structures and a connection ring structure formed therebetween. The first engaging structure is engaged with the second engaging structure of the first ring structure for positioning the first ring structure on the projection lens. The second ring structure is clamped between the holding casing and the containing casing for sealing the containing space cooperatively with the connection ring structure and the first ring structure when the containing casing is fixed to the holding casing.

Abstract: A touch projection system includes a light source device, a micromirror device, and an image-capturing device. The micromirror device can provide three reflection directions. The micromirror device can selectively reflect projection light emitted by the light source device in one of the reflection directions to project the reflected projection light onto a screen to form an image. The micromirror device also can reflect image light from the screen in another one of the reflection directions. Further, the micromirror device can reflect the image light from the screen in the other one of the reflection directions, which has a larger deflection angle, to be received by the image-capturing device, for example for determining a touch operation performed on the screen. Thereby, the limitation of structural interference by other components to the image-capturing device is reduced, so that the touch projection system can be assembled in a compact configuration.

Abstract: A projection device includes a first light source, a second light source, a driving unit, a reflecting member and a light integrator. The driving unit and the first light source are located at opposite sides of a second light axis of the second light source. The driving unit and the second light source are located at opposite sides of a first light axis of the first light source. The driving unit drives the reflecting member to move between a first position and a second position. When the reflecting member is located at the first position, the first light source emits a first light along the first light axis to the light integrator. When the reflecting member is located at the second position, the second light source emits a second light along the second light axis and the reflecting member reflects the second light to the light integrator.
