摘要: An image shifting module for shifting imaging positions of sub-images projected on a screen in each frame, and an optical projection device using the same are provided. The image shifting module includes a first vibration mechanism and a second vibration mechanism. The first vibration mechanism is disposed on the transmission path of the sub-images and shifts the sub-images projected on the screen by a first distance along a horizontal direction in each frame time. Moreover, the second vibration mechanism is disposed on the transmission path of the sub-images and shifts the sub-images projected on the screen by a second distance along a vertical direction in each frame time. Through this image shifting module, the image resolution can be increased.

摘要: 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.
