Abstract: The invention refers to a diffusion plate and a backlight module having the diffusion plate. The diffusion plate comprises a plate-body and a plurality of pyramid-like structures arranged on a surface of the plate-body. Each pyramid-like structure has a bottom surface, a first convex portion and a second convex portion. The first convex portion and the second convex portion have different vertex angles, and therefore the pyramid-like structure can also be called as “pyramid-like structure with multiple vertex angles”. The pyramid-like structures with multiple vertex angles can increase the light splitting points, which can improve the light splitting effect of the diffusion plate. The light source of a single light-emitting diode can be divided into eight point-light sources (light splitting points) or more, which is double the number of light splitting points compared with the traditional pyramid structure with single vertex, and thus can greatly improve the light diffusion effect.

Abstract: A vibration and shock isolator may include a resilient member and a compressing member. The resilient member may be connected between a vibrating source and an object. The compressing member may provide the resilient member with a compression displacement in accordance with the vibration characteristics applied to the resilient member from the vibrating source to change stiffness of the resilient member. Thus, a designed natural frequency of the isolator may be simply changed using the shape memory wire to suppress vibration amplification. As a result, the isolator may effectively relieve the shock and the vibration so that a structural stability of a structure may be ensured. Further, the isolator may have a simple structure so that the isolator may have improved reliability and durability.
