Abstract

The utility model relates to an optical fiber enlarging show screen, which is composed of a transparent plate with texture, an optical fiber array plate opened with optical fiber positioning holes, and fiber optic bundles mounted on the optical fiber array plate. The optical fiber enlarging show screen has simple structure, and has obvious superiority than traditional optical fiber show screens; in particular, the optical fiber enlarging show screen can enlarge dynamic images, and can be used as various coloured show screens with high resolution.

Description

Optical fibre enlarging show screen

The utility model relates to a kind of display device, and particularly a kind of colored optical fiber amplifies display screen.

Optical fiber on the market shows goods at present, generally be to adopt plastic optical fiber output to show, and this method, display performance is poor, therefore is difficult to apply.

The purpose of this utility model is to provide a kind of simple in structure, and power consumption easy to process is little, lose effective, the display screen that sharpness is high, particularly the optical fiber that dynamic image can be amplified amplifies display screen.

The utility model is made up of fibre bundle 5, color liquid crystal light valve panel 7, tunable light source 8, casing 4, the optical fiber array plate 3 that has the transparent panel 1 of texture and have fibre bundle pilot hole 2 thereafter.

The utility model is owing to adopted the transparent panel that has texture, woven design texture particularly, the optical fiber array plate that has the fiber orientation hole has been installed in the back of transparent panel 1, optical fiber inlays in the hole of optical fiber array plate, fibre bundle pilot hole pitch-row depends on the size that the pixel of former image is exaggerated, and this display screen can amplify dynamic image and sharpness is better than traditional display screen.

The utility model low price, simple in structure, easy for installation, visual, amplification effect is good, is desirable amplification display screen.

With reference to the accompanying drawings embodiment of the present utility model is described in detail below:

Fig. 1 is that synoptic diagram cuts open in the utility model structure office

Transparent panel 1, fiber orientation hole 2, optical fiber array plate 3, casing 4, fibre bundle 5, fiber array image receiving end 6, liquid crystal light valve plate 7, tunable light source 8.

The utility model comprises fibre bundle 5, tunable light source 8, and color liquid crystal light valve panel 7, and form by the transparent panel 1 of band texture and the optical fiber array plate 3 that has fiber orientation hole 2 thereafter.When 40 times of about 3 inches zoomings of receiving end, available 400 millimeters * 300 millimeters, thick 4 millimeters, one of the transparent panel of band texture, 400 millimeters * 300 millimeters, one in thick 3 millimeters organic glass, press 0.35 millimeter of aperture on it, pitch-row is drilled with about 30,000 holes for 2 millimeters and makes optical fiber array plate, is installed on the casing 4 two plates are parallel, and the crack can be adjusted as required between two plates.Optical fiber is cut into 300 millimeters long, 30,000, per 200 is one group, one end is evened up closely and the horizontal direction gummed, totally 150 groups, 150 groups of optical fiber stack and vertically compose diagonal line again and are approximately 3 inches rectangle section, through receiving on the fiber array image receiving end 6 as the receiving end of fibre bundle after the bright and clean processing, the other end correspondence of fibre bundle is passed the hole 2 on the optical fiber array plate 3, is heated to be semisphere after evening up, and is the convex lens shape, like this, picture element on the liquid crystal light valve plate 7 of every optical fiber correspondence is an end of convex lens shape through fiber optic conduction to optical fiber, by convex lens optically focused, shine on the transparent panel 1 that has texture, because the astigmatism effect of texture on its plate, on display panel, just demonstrate and the corresponding pixel that has been exaggerated of liquid crystal light valve plate 7 pixels, the view picture image just has been exaggerated.

It is low that this optical fiber amplifies the display screen cost, amplify about 9～10 kilograms of the used homemade optical fiber of display screen as 2 * 1.5 meters optical fiber, per kilogram is about 80 yuans, because cost is low, zooming is effective, manufacturing procedure is simple, therefore can be made into various large-sized high-resolution colored optical fibers and amplifies display screen, is applied to the every field of national economy.

Claims

1, a kind of optical fiber amplifies display screen, comprises fibre bundle 5, color liquid crystal light valve panel 7, tunable light source 8 and casing 4, and of the present utility model being characterised in that reaches the optical fiber array plate 3 that has fiber orientation hole 2 thereafter by the transparent panel 1 that has texture and form.
