Abstract: A bonding method for using a bonding apparatus includes: transporting and reeling a carrier tape which is packaged with an adhering component, on a pressing assembly, and bending the carrier tape through a bending member to be divided into an input section and an output section; driving a roller to indirectly press and abut a front end of the adhering component to bring the adhering component into contact with a bonding start point a base component; and rolling the roller over the carrier tape to attach the adhering component to the bonding area while moving the bending member to indirectly scrape the adhering component from the carrier tape so as to firmly attach the adhering component to the base component without generation of air bubbles.

Abstract: A bonding device includes a first carrying module for a tape assembly to be disposed thereon and reeling a carrier tape and a cover tape, a driving module disposed to drive an up-down movement and a rotation of the first carrying module, a second carrying module movably disposed on the first carrying module, and a bonding module disposed on the second carrying module. The bonding module includes a bending member on and through which a carrier tape is reeled and bent to be divided into an input section and an output section. The bending member is moved together with a roller, during rolling of the roller, to indirectly scrape an adhering component from the carrier tape so as to facilitate attachment of the adhering component to the base component.

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 uniform reflective light-guide for accompanying an edge light source to form a backlight module for an LCD display includes a light-guiding layer and a reflective layer. The light-guiding layer further defines a light-introducing surface and a light-exiting surface. The light-introducing surface is to allow lights emitted from the edge light source to enter the light-guiding layer. The light-exiting surface perpendicular to the light-introducing surface is to allow at least a portion of the lights to leave the light-guiding layer. The reflective layer is to reflect the incident lights back to the light-guiding layer. The reflective layer and the light-guiding layer are manufactured integrally into a unique piece by a co-extrusion process so as to avoid possible existence of an air spacing in between. A reflective surface is defined to interface the reflective layer and the light-guiding layer, and a three-dimensional micro-structure is constructed on the reflective surface.
