    Abstract: A cooling device includes a printed circuit board having a hole, a light valve disposed on the front surface of the printed circuit board, and a thermal diffuser disposed on the back surface of the printed circuit board. Therefore, the thermal diffuser can contact the light valve through the whole, and directly receives heat from the light valve. Guided by partition wall and channels, a fan of the thermal diffuser sucks airflows into stream channels to fully exchange heat with diffuser fins for cooling the light valve, so that the cooling efficiency of the light valve can be increased. Then, the airflows blow and cool the printed circuit board to form an integrated cooling system.

    Abstract: An image displacement device includes a first grating and a second grating. The first grating has a first surface and a second surface opposite the first surface, the first surface receives image beams, and the image beams leave the first grating by the second surface. The second grating is disposed downstream from the first grating in a light path and has a third surface and a fourth surface opposite the third surface. The third surface receives the image beams, and the image beams leave the second grating by the fourth surface. The image beams are projected to form a plane image comprised of pixels, each pixel is displaced in a direction by the image displacement device, and a displacement of each pixel is smaller than five times a width of one pixel.

    Abstract: A low thermal-drift optical lens includes a first lens group, a second lens group and an aperture stop. The first lens group includes a first lens and a second lens, and the second lens group includes a third lens and a cemented lens. The aperture stop is disposed between the second lens and the cemented lens, and a lens with a refractive power of the low thermal-drift optical lens closest to the minified side has at least one inflection point. In an operating temperature range of −40° C. to 80° C., a thermal drift of the low thermal-drift optical lens relative to a focal plane at 25° C. is less than or equal to 10 um.

    Abstract: A cooling device for an optical engine includes a cooler module, a first temperature/humidity sensor, a second temperature/humidity sensor and a temperature control system. The cooler module includes a cooler, the cooler has a heat-absorbing surface and a heat-dissipating surface, and the heat-absorbing surface is thermally coupled to at least one heat source. The first temperature/humidity sensor is disposed in a position not in contact with the cooler module, and the second temperature/humidity sensor is disposed on the heat-absorbing surface. The temperature control system is capable of receiving a signal from the first temperature/humidity sensor, receiving a signal from the second temperature/humidity sensor, and transmitting a signal to the cooler module.

    Abstract: A display system including a display device and a light combining device is provided. The display device includes a first display region and a second display region. The light combining device has a first surface and a second surface opposite to the first surface. The first surface is capable of reflecting a first light beam from the first display region to an observing region for forming a first virtual image. The second surface is capable of reflecting a second light beam from the second display region to the observing region for forming a second virtual image. A curvature of the first surface is different from a curvature of the second surface, and a position of the first virtual image is different from a position of the second virtual image.
