Optical fiber with function of image compensation

Abstract

Provided in the invention is an optical fiber with function of image compensation. The optical fiber comprises an optical member formed by combination of a plurality of fibers in same-direction arrangement. The optical member includes an output end surface, an input end surface and a lateral adjacent surface. The output end surface is formed by collection of cross sections of ends of the fibers, wherein the cross sections are in geometric shapes like perfect circles or regular polygons. The input end surface is formed by collection of cross sections of the other ends of the fibers, wherein thecross sections are in geometric shapes like perfect circles or regular polygons. The lateral adjacent surface extends in a same direction as the fibers. On the basis of the structure, the image displayed by the picture can keep the predetermined brightness no matter when the user watches the picture in a front or lateral direction.

Description

technical field [0001] The invention provides an optical fiber, especially an optical fiber with image compensation. The output end face of the transmission is tangent and the cross sections of multiple optical fibers formed are perfect circles or regular polygons. The input end face is obliquely cut and the polygon corresponding to the output end face appears Non-perfect circle or non-regular polygon, in order to maintain a certain brightness regardless of viewing the image from the front or side view. Background technique [0002] Fig. 13 and Fig. 14 are schematic diagrams of conventional optical fiber manufacturing methods and the specific application of the first embodiment. Fig. 13 firstly compresses an optical member 50 by a plurality of optical fibers 501 through pressure, and then obtains the optical member 50 in a triangular columnar shape by cutting as shown in Fig. 14 , the optical member 50 has an output end face 51, An input end face 52 and a side adjoining sur...

Problems solved by technology

[0009] In order to solve the problem of the presentation of the patterns affected by the end edges 71 in Figure 18, the industry has proposed the following Figure 23 Shown is a quadrilateral optical member 90, the optical member 90 directly obliquely cuts the part of the original end to form a hypotenuse 91, so as to avoid the problem that the image cannot be presented, but the plurality of optical fibers 92 constituting the hypotenuse 91 will like Figure 24 The disclosed oblique section of the optical fiber 92 produces the problem of light deflection, so that the image brightness is good when the user watches from point N (or point L), but the image will be dark when viewed from point O (or point M), and then Produces brightness differences in images
