Embodiment Construction

[0032] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments of the present invention will be exemplified below, together with the accompanying drawings, and described in detail as follows.

[0033] Such as image 3 , 4 As shown, the composite light-concentrating sheet 1 with diffusing particles according to the preferred embodiment of the present invention includes a substrate 11 , several curved prism units 12 and several diffusing particles 13 . The base material 11 has a first surface 11a and a second surface 11b, and allows light to pass through. The first surface 11 a of the substrate 11 is used as the light emitting side of the substrate 11 , and the second surface 11 b is used as the light incident side of the substrate 11 , and vice versa. The curved prism unit 12 has a curved profile microstructure unit (microstructure), the curved prism unit 12 is arranged adjacent to each other on...

Abstract

A compound condenser with diffusion particles is provided, which comprises a substrate and a plurality of diffusion particles. The substrate is provided with a first surface and a second surface. The bend prism units are arranged on the first surface of the substrate and the diffusion particles are mixed into the bend prism units at least, which can make the ray through the second surface generate diffusion at the same time. The bend prism units have at least one bend extension curved surface to form a appropriate surface curvature change and lead the ray to generate refraction above two-dimension, and then reflect the bend prism units.

Description

technical field [0001] The invention relates to a composite light-condensing sheet with diffusing particles, especially a light-condensing sheet for Liquid Crystal Display (LCD), in which several curved prism units are formed on one surface, mixed with several diffusing particles, Composite light-concentrating sheet that provides dual effects of diffusion and light-concentrating. Background technique [0002] For existing spotlights, please refer to figure 1 , 2 As shown, it discloses that a light concentrating sheet 9 includes a substrate 91 and several prism units 92 , and the prism units 92 are arranged in parallel on a first surface of the substrate 91 . The prism unit 92 is composed of two inclined surfaces, which are used for refracting light so as to generate light concentration. For example, when a light ray 93 is incident on the substrate 91 with a larger incident angle relative to a second surface of the substrate 91 (that is, the light ray 93 is not perpendicul...
