Description
Technical field
The invention relates to a kind of light-collecting component, can the gain light-collecting component structure of optically focused diaphragm of brightness improving brightness uniformity of the backlight module that refers to be used for the liquid crystal visual organ especially.
Background technology
The photoelectricity correlation technique is constantly weeded out the old and bring forth the new in recent years, adds the arrival of digital times, and then has promoted the flourish of LCD market.LCD (Liquid Crysta1 Disp1ayer; LCD) have that high image quality, volume are little, in light weight, advantage such as low voltage drive, low consumpting power and applied range, therefore be widely used in consumer electronics or computer products such as Portable TV, mobile phone, mobile computer and desktop display, and replace cathode-ray tube (CRT) (Cathode Ray Tube gradually; CRT) become the main flow of display.
Backlight module is one of key part and component of display panels.Because liquid crystal itself can't be luminous, therefore need to use backlight module to supply light source, can show normal and the well-balanced image of brightness so as to making liquid crystal panel.Usually have light-collecting component in the backlight module, for example diffusion sheet (diffusion sheet) and brightness enhancement film (brightness enhancement film) to increase the briliancy of emergent ray, make the distribution of emergent ray can be more even.
For further being the effect of the optically focused blast of gain backlight, two-layer above light harvesting membrane layer can be stacked.
Yet at present with the two-layer above stacked shortcoming that may cause of light harvesting diaphragm: the prism arrangement structure of one, the interference of light---known rule easily with the striped of light source and liquid crystal panel generation optical interference, influences picture display effect.Two, static dirt---two layers the folded structure of light harvesting diaphragm easily produces static dirt (easily adsorbing the foreign substance pollution structure) because of the friction between surface of contact.In view of this, the design of light harvesting diaphragm still has the demand of improvement.
Summary of the invention
Therefore this novel purpose is providing a kind of light-collecting component exactly.
According to this novel above-mentioned purpose, a kind of light-collecting component is proposed, it comprises base material and a plurality of prism.A plurality of prisms are arranged on the base material continuously, form a prism paddy between adjacent prisms, and the bottom of all prism paddy is positioned at same plane to form a reference field.These a plurality of prisms are divided into first prisms and second prisms.First prisms has a relative peak and is higher than reference field one first height, and the drift angle bisector of each prism of first prisms is all perpendicular to reference field.Second prisms has a relative ebb and is higher than reference field one second height, and the drift angle bisector of each prism of second prisms is neither perpendicular to reference field.Each first prism and each second prism alternately are arranged on the base material continuously, and first height is greater than second height.
According to this novel above-mentioned purpose, a kind of light-collecting component is proposed, it comprises the first light harvesting film and the second light harvesting film.Two opposite faces of each light harvesting film are a prism facets and a plane.The prism facets of the first light harvesting film contacts the plane of the second light harvesting film.Each prism facets comprises a plurality of prisms arranges continuously, and forms a prism paddy between adjacent prisms.The bottom of all prism paddy is positioned at same plane to form a reference field.These a plurality of prisms are divided into first prisms and second prisms.First prisms has a relative peak and is higher than reference field one first height, and the drift angle bisector of each prism of first prisms is all perpendicular to reference field.Second prisms has a relative ebb and is higher than reference field one second height, and the drift angle bisector of each prism of second prisms is neither perpendicular to reference field.Each first prism and each second prism alternately are arranged on the base material continuously, and first height is greater than second height.
From the above, after this novel light-collecting component of application multilayer is stacked, can reduce the striped of optical interference, promote picture display effect, reduce simultaneously because of the static dirt that friction produced between the light-collecting component surface of contact.
