Abstract
The invention discloses a composite prismatic lens, which comprises a lower substrate layer, wherein a lower prism layer is arranged on the lower substrate layer; an adhesive layer is arranged on the lower prism layer; an upper substrate layer is arranged on the adhesive layer, and an upper prism layer is arranged on the upper substrate layer; both the upper prism layer and the lower prism layer comprise multiple lines of triangular prisms and multiple lines of half-cylinders, the triangular prisms and the half-cylinders are alternately distributed and are connected at the lower ends, and the corners of the triangular prisms are provided with arc surfaces; the triangular prisms of the upper prism layer correspond to the half-cylinders of the lower prism layer, and the half-cylinders of the upper prism layer correspond to the triangular prisms of the lower prism layer; the lower substrate layer is 200-300 microns thick, the upper prism layer and the lower prism layer are 30-80 microns thick, and the thickness of the adhesive layer is 10%-30% of that of the upper prism layer. The composite prismatic lens disclosed by the invention integrates functions of two prismatic lenses, has an excellent optical effect, and is capable of effectively improving the brightness and light uniformity of a backlight module and the yield of the backlight module.
Description
Technical field
The present invention relates to a kind of prismatic lens.
Background technology
Recently, develop various panel display apparatus (Flat Panel Display, FPD), and therein, liquid crystal indicator (Liquid Crystal Display, LCD) be to utilize according to the liquid crystal transmittance of applied change in voltage, the electron device that the various electric signal that various devices are produced are converted to visual information and transmit.
Because of liquid crystal indicator be there is no self light emitting source be subject to light type device, therefore needs can irradiate the independent light supply apparatus of whole picture being made up of liquid crystal display in the back.Above-mentioned liquid crystal indicator is referred to as backlight module (Back Light Unit, BLU) with lighting device.
In liquid crystal display, backlight module has played the effect that uniform area light source is provided.Backlight module comprises lamp source, reflector plate, site, light guide plate, lower diffusion barrier, prismatic lens and upper diffusion barrier successively.Wherein, lower diffusion barrier mainly has the effect of diffusing light, can make light source become uniform area source, and prismatic lens can play further concentrated light, improves the effect of brightness, and upper diffusion barrier Main Function is protection prism and improves visible angle.Cooperatively interacting of these diaphragms just, just makes us can obtain the uniform area source of high brightness.
In the time carrying out assembling backlight, between diaphragm, can there is mobile, friction mutually, cause diaphragm to scratch, meanwhile, between film and film, also likely sneak into dust impurity etc., thereby backlight module yield (or claiming qualification rate) is reduced.
Summary of the invention
Mutually to move, rub in order to solve between the each diaphragm of existing backlight module, cause the mutual scuffing between diaphragm, or between diaphragm, in the time cutting or assemble, sneak into dust or chip, the phenomenon that the qualification rate of backlight module production and assembly is reduced, the invention provides a kind of composite prism sheet that integrates two prismatic lens functions, can effectively improve the brightness of backlight module and the homogeneity of light, and improve the group yield of mould backlight.
The technical scheme that the present invention solves its technical matters is: a kind of composite prism sheet, comprise lower substrate layer, on described lower substrate layer, there is lower layers of prisms, described lower layers of prisms is provided with one deck gluing layer, described gluing layer is provided with substrate layer on one deck, and described upper substrate layer is provided with layers of prisms on one deck;
Described upper layers of prisms and lower layers of prisms include several rows triangular prism and several rows semicolumn, and described triangular prism and semicolumn are alternately distributed and are mutually connected in lower end, and the edges and corners of described triangular prism are arc surface;
The triangular prism of described upper prism is corresponding with the semicolumn of described lower prism, and the semicolumn of described upper prism is corresponding with the triangular prism of described lower prism;
The thickness of described lower substrate layer is 200 ~ 300 μ m, and the thickness of described upper layers of prisms and lower layers of prisms is 30 ~ 80 μ m, and the thickness of described gluing layer is 10% ~ 30% of upper layers of prisms thickness.
Beneficial effect of the present invention is: integrate two prismatic lens functions, and described prismatic lens has good optical effect, can effectively improve the brightness of backlight module and the homogeneity of light, and improve the group yield of mould backlight.
