Abstract: A high brightness diffusion plate for homogenizing light beams provided by at least one light source of a backlight module to a display panel is provided, which includes a diffusion layer, a transmittance layer, and a plurality of connecters. The transmittance layer is disposed above the diffusion layer, and the connecters are connected between the diffusion layer and the transmittance layer. Since the high brightness diffusion plate of the present invention is an integrated structure and is stronger, the present invention is not only easier for being assembled inside the backlight module, but also makes the light source provided by the backlight module being more homogeneous.

Abstract: A magnetic altitude adjusting mechanism is described. The magnetic altitude adjusting mechanism includes a slide, a track, and a magnetic repulsive device. The slide including a magnetic piece is bar-shaped. The magnetic piece is configured in the slide. A longitudinal direction of the magnetic piece and a longitudinal direction of the slide are the same. The slide is coupled to the track so as to move along the track and be prevented from rotation thereon. The magnetic repulsive device is disposed on one end of the track to generate a magnetic repulsive force for fixing the slide on the track. The slide stops on a predetermined position with the magnetic repulsive force while an external force is released after the slide is adjusted to the predetermined position by the external force.

Abstract: A color wheel includes a rotating shaft extending upwardly from a support face and having an engaging portion formed on the rotating shaft. A color filter plate set is disposed around the rotating shaft over the support face and includes a plurality of angularly arranged color filter plates. A first pressing ring is disposed between the color filter plate set and the support face. A second pressing plate is sleeved around the rotating shaft over the color filter plate set, and a fixing member is disposed around the rotating shaft over the second pressing plate. The fixing member engages the engaging portion and presses the second pressing plate and the color filter plate set so that the color filter plate set is prevented from moving outwardly from the support face.

Abstract: A torque adjusting mechanism including a shaft, a main body, and an adjusting device is provided. The main body has a circular wall and a through hole disposed therein for coupling to the shaft. The adjusting device disposed on the main body includes an adjusting hole, an adjusting button and an elastic body disposed inside the adjusting hole. The adjusting hole is perpendicular to the through hole and penetrates the circular wall. The adjusting button coupled to the adjusting hole can be adjusted along the adjusting hole. One end of the elastic body contacts with the adjusting button and the other end presses on the shaft. Therefore, the elastic body can provide a predetermined torque between the shaft and the main body and further increase the torque between the main body and the shaft.

Abstract: A stepless height adjusting apparatus includes a slider, a slide way, and an elastic supporting device. The slider is an axial symmetry bar. The axial symmetry bar has a larger cross section perpendicular to the axis thereof on the top portion and a smaller cross section perpendicular to the axis thereof on the bottom portion so as to form an incline on the side surface. The slider couples to the slide way to move on the slide way. The elastic supporting device is disposed on the top portion of the slide way to support the slider with balance forces between the elastic supporting device and the incline of the slider. When an external force is pushing the slider, the slider may move along the slide way. When the external force is removed, the slider may stop at a determined position on the slide way by the balance force.

Abstract: A torsion adjusting module is described. The module includes a shaft, a main body, an elastic member, and an adjusting device. The main body is made of an elastic material with an unclosed circular structure to couple to the shaft. A distance is formed at ends of the unclosed circular structure to keep a gap between the main body and the shaft. The elastic member is disposed in the gap between the shaft and the main body. The adjusting device is disposed at the ends of the unclosed circular structure to adjust the distance between the ends to adjust a torsion between the shaft and the main body. A predetermined torsion is set between the shaft and the main body before the adjusting device adjusts the adjusting device. The torsion is increased when the adjusting device is pressed to shrink the distance of the ends.
