Description
Technical field
The utility model relates to a kind of even Wave surface light focusing sheet, particularly about being used in the concentration piece of display (Display), the corrugated of its light focusing unit has even curvature, to improve optical characteristics (optical characteristic).
Background technology
Known concentration piece, please refer to shown in Figure 1, world patent WO96/23649 number " BRIGHTNESS ENHANCEMENT FILM " discloses a concentration piece, and this concentration piece comprises a substrate (base) 1 and several prisms 2, and this prism 2 is arranged on the surface of this substrate 1.This prism 2 is made up of one first plane 2a and one second plane 2b, and it is in order to refracted ray, so that produce the optically focused phenomenon.
Yet this first plane 2a and the second plane 2b belong to the plane, promptly are different from curved surface, so the plane only can produce refracted ray at one dimension, so this concentration piece only produces the optically focused phenomenon at one dimension.
Another known concentration piece, please refer to shown in Figure 2, United States Patent (USP) the 6th, 277, No. 471 " Wave surface light focusing sheet " patents, it discloses a Wave surface light focusing sheet (brightness enhancement film) and comprises a substrate 11 and a corrugated slice layer (brightness layer) 12.This substrate 11 has a upper surface and a lower surface.This corrugated slice layer 12 has a upper surface and a lower surface, arranges several corrugated slices (rippled ridge) 121 on its upper surface.This corrugated slice 121 is to be rearranged by several light focusing unit (brightness unit) 122, and this light focusing unit 122 has curved surface, and this curved surface makes this light focusing unit 122 can produce the optically focused phenomenon of two dimension in order to carry out the light refraction of two dimension.The surface is for pasting surface under this corrugated slice layer 12, to form Wave surface light focusing sheet on this substrate 11.
Shown in Fig. 1,2, this United States Patent (USP) the 6th, 277, the curved surface of No. 471 light focusing unit 122 is reached two-dimentional optically focused, utilize one of this light focusing unit 122 that curved surface is substituted the first plane 2a and the second plane 2b of world patent WO96/23649 number, improve the first plane 2a of world patent WO96/23649 number and the second plane 2b whereby only in the shortcoming of one dimension optically focused.
