Abstract: A low reflective, anti-static and anti-fouling optical film, and a forming method thereof are disclosed. The forming method includes mixing an alkoxy silane, a fluoride-modified alkoxy silane, a conductive material and a pores formation agent to form a coating composition. Subsequently, the coating composition is solidified to form an optical film. The optical film includes a silicon oxide compound with fluorine element, the conductive material mixed therein, and a plurality of three-dimensional mesoporous. Therefore, the optical film of the present invention can simultaneously provide a low reflection, an anti-static effect and an anti-fouling effect.

Abstract: Disclosed is a reactive polymer of the following representative formula: R4—R3b—NH—CO—R2b—CO—NH—R1—NH—CO—R2a—CO—NH—R3a—R4 wherein R1 is alkylene, arylene or the combination thereof, R2a or R2b is a linker, R3a and R3b is a cross-linked poly —Si—O— group, and R4 is a vinyl functional group.

Abstract: The present invention relates to a multiple-coating particle and an anti-glare film having the same. The anti-glare film includes a transparent resin and a plurality of multiple-coating particles. The multiple-coating particles are evenly distributed in the transparent resin. The multiple-coating particle is composed of at least two layers of the distinct transparent materials so as to scatter and refract light due to different refractive indexes and to provide anti-glaring effect.

Abstract: The present invention provides an antiglare film, which includes a transparent resin layer, a plurality of transparent hollow particles and a plurality of transparent solid particles. The hollow particles and the solid particles are distributed in the transparent resin layer, while the hollow particles are partially exposed thereon. The refraction index of the hollow particles and the refraction index of the solid particles are different from the refraction index of the transparent resin layer. Applying both the solid particles and the hollow particles mixed together can lead the antiglare film to have an excellent antiglare property, a high contrast and a great clarity.

Abstract: A trackball in one embodiment includes a socket mounted on a PCB and including an upper chamber, a lower chamber in communication with the upper chamber, an opening on a periphery of the lower chamber, rollers disposed around a bottom of the upper chamber, a ball mounted in the upper chamber and rotatably supported by the rollers, a ring cover secured to the socket for projecting an upper portion of the ball therefrom, a light source (e.g., laser diode) mounted in the opening for emitting light onto a lower portion of the ball, and a photosensor mounted under an aperture of the PCB. Rolling the ball will reflect the light from the ball to the photosensor such that the rotational movement of the ball can be converted into a digital signal useable to move a cursor a corresponding distance and direction on a display of, for example, a keyboard.
