Abstract: An autostereoscopic display device and a method are provided. The autostereoscopic display device includes a display panel, a plurality of collimation units, and a plurality of refraction units. The display panel has a plurality of pixel groups, each of the pixel groups includes a plurality of pixels, all of the pixels are arranged in an array, and the display panel emits image light in a light-emitting direction. Each of the collimation units is located at one side of at least one pixel to receive the image light, and each of the collimation units converges the image light into collimated image light. Each of the refraction units is located in front of at least one pixel on two sides of a center of the pixel group, so as to receive the collimated image light and refract the collimated image light into refraction image light.

Abstract: A beam splitting apparatus applicable for a projecting system is provided. The beam splitting apparatus comprises a shaft, a plurality of dichroic mirrors and a housing. The shaft and the dichroic mirrors are surrounded and sealed by the housing. The outer surface of the shaft is screw-surrounded by the dichroic mirrors. The dichroic mirrors rotate with the shaft and split an incident light into a plurality of primary color light beams, and scroll the position of the primary color light beams circularly. The beam splitting apparatus can reduce the noise and the energy loss, and raise the display frames rate to increase the display quality.

Abstract: A charging system for a wireless mouse and charging method are disclosed. The system comprises a transceiver unit having a first charging module and a circuit, and a wireless mouse body having a second charging module and a control circuit. When the wireless mouse is in normal operation, the transceiver unit is electrically connected to a port of a computer to charge power from the port by using the first charging module and to transfer data between the computer and the wireless mouse via the circuit. Alternatively, when the operation of the wireless mouse is done, the transceiver unit is plugged or snapped in the wireless mouse body to charge the second charging module with power by discharging the charged first charging module. Furthermore, when the power of the wireless mouse is used up, the second power storage unit of the second charging module of the wireless mouse body is directly replaced with the charged first power storage unit of the first charging module of the transceiver unit.

Abstract: A scrolling device with color separation and a projection system incorporating same are disclosed. The scrolling device comprises a scrolling shaft and a plurality of dichroic mirrors that are spirally arranged as screw threads on the scrolling shaft. The scrolling device rotates around predetermined axis, and the dichroic-mirror threads can separate an incident light beams into two or more color light beams, thereby scrolling the positions of these color beams. The scrolling color beams are then transmitted to a light modulating panel in the projection system. Therefore, a single-panel projection system with color scrolling function is achieved.
