    摘要： A planar light guide film for a backlight unit having at least one point light source is disclosed. The light guide film includes a light input surface for receiving light from the point light source, a light redirecting surface for redirecting light received from the light input surface and a light output surface for outputting at least the light redirected from the light redirecting surface. The light input surface further includes a composite lens structure having a first and second circular tip segment each circular tip segment with a first contact angle, and a first and second circular base segment each circular base segment with a top and bottom contact angle, the contact angles of the circular base segments being less than the contact angle of the circular tip segments.

    摘要： The present invention provides a planar light guide film for a backlight unit having at least one point light source, the light guide film comprising a light input surface for receiving light from the point light source, a light redirecting surface for redirecting light received from the light input surface and a light output surface for outputting at least the light redirected from the light redirecting surface. The light input surface further comprises a composite lens structure having a circular tip segment with a first contact angle, and a first and second elliptical base segments with a second contact angle, the second contact angle being greater than the first contact angle and the second contact angle being equal to each other andwherein the circular tip segment satisfies the following equation: y1=a1+√{square root over ((r12−x2))} and the elliptical base segments satisfies the following equations: y4=d4+b4×√{square root over ((1−((x+c4)/a4)2)} y5=d5+b5×√{square root over ((1−((x−c5)/a5)2)}.

    摘要： A backlight apparatus for directing light toward a display panel and the resulting display device comprises a solid lightguide comprising opposite TIR surfaces, containing a desired pattern of light redirecting surface features located between the TIR surfaces and interrupting one of the TIR surfaces, the features having a refractive index differing from that of the solid material of the light guide. Such an apparatus provides a more even light distribution to the display.
