Abstract
The utility model is used for the screen of a television kinescope through optical fibers. The utility model has no black slit or distortion amplification. The utility model can be used for the display with a high definition. The utility model is characterized in that the integration is a matrix which is composed of m x n amplifying unit devices; each unit is cooperated with an input frame by a bracket at the end surface of the kinescope; the input frame is provided with small holes whose number is the same as the number of luminous points which are preassigned by a computer; big holes with the same number corresponding to the input frame are arranged in an output frame; fiber optic bundles which are composed of optical fibers with unequal diameters are arranged between the input frame and the output frame and are separately and mutually connected with small holes and big holes. A picture which is outputted can keep the original brightness, sharpness, color saturation and contrast. The picture is undistorted.
Description
The utility model relates to optical fiber and is used for the television picture tube screen image is done undistorted amplification, and obtain a kind of display device of the standard straight angle plane display screen that new area increases, can be widely used in commerce, advertising, medical treatment and sporting world's large scale display.
The at present domestic corrective measure that only has the black seam of pair kinescope screen curtain wall to eliminate, used the combined system of major diameter lens and concentric circles polarization plasticity plate, but there is not the image multiplication effect, this system can not eliminate black seam fully, there is the thin black seam that can not disappear simultaneously between the concentric circles polarization plates, and every index such as definition, brightness, contrast descends a lot, whole-screen brightness is inhomogeneous, the visual angle also narrows down in 40 degree, complex structure need involve great expense by large-screen right-angle plane picture tube formation matrix.
Task of the present utility model provides the matrix that a kind of on-right angle plane small size chromoscope constitutes, zoom into large-size direct angle plane screen, not only can show general intermediate-resolution TV image, and the high definition satellite television programming about energy display of high resolution computer display monitor central monitoring system or 1200 lines, especially can eliminate the black in length and breadth seam that forms because of the glass bulb structure in the general tv screen wall fully isolates, the complete sum of recovering entire pattern is continuous, and every demonstration index is compared unconverted nothing and isolated black seam TV image amplifying device with former screen.
For finishing the technical scheme that above-mentioned goal of the invention is taked: light relies on the total reflection propagation of dielectric boundaries to advance in optical fiber, and lose minimum, the route of transmission of fibre-optic degree of crook and light is irrelevant simultaneously, so utilize one section not equal diameter optical fiber, its two ends can be realized the amplification of light or be dwindled, ratio is the ratio of the area of two different cross sections, the propagation of above-mentioned not isometrical optical fiber, obtain the output that a light-emitting area increases in its larger diameter end cross section, and brightness variation and change color and input are synchronous, its light spot form is identical with end surface shape, irrelevant with light source, the ratio of the intensity of illumination of illuminance and light source input is the inverse that light-emitting area increases multiple, therefore can realize the non-lens amplification of not isometrical optical fiber to light.For this reason can be as the amplification of TV image, the picture tube of ordinary color tv set is all with the cathode emission electronics, in the acceleration of high voltage electric field with add under the deflecting action of electromagnetic field, screen is scanned, make the fluorescent material pointwise luminous and form the demonstration of image, the demonstration that is every images is all with the different luminosity of luminous point one by one and glow color and piece together, one images can be divided into various luminous points, with one section not the smaller diameter end cross section of isometrical optical fiber aim at a luminous point on the screen, then one and this brightness will appear in larger diameter end, the circular light spot of the amplification that color changes synchronously, the light beam that each luminous point on the chromoscope screen all uses the not isometrical optical fiber of same configuration to form is drawn amplification, just can obtain the right-angle plane chromatic image that a width of cloth amplifies at the major diameter output end face, its brightness, contrast, the variation of color saturation and image are gone up original definition, all with picture tube on consistent.
According to different requirements to resolution, optical fiber radical contained in the not isometrical fiber bundle is different, also constituted different purposes, applicable to the intermediate-resolution large scale video screen of no black piece and the high Resolution and Large Size video screen of no black piece, can make large scale colour TV screen into by middle size colour TV equally.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model amplifying device cellular construction figure;
Fig. 2 is not isometrical optical fiber structure figure;
Fig. 3 is an input frame shelf structure schematic diagram;
Fig. 4 is the output framework structural representation;
Fig. 5 is output framework left side TV structure figure;
Fig. 6 is the end view of the TV image amplifying device of m * n unit combination;
Fig. 7 is the TV image amplifying device vertical view of m * n unit combination.
The utility model is formed matrix by m * n amplifying device unit, as shown in Figure 6 and Figure 7, each unit cooperates input framework 3 by the picture tube support on the picture tube 1 glass bulb end face 2, its picture tube support 2 is that 1mm is to avoid scratch screen shell glass with constituting kinescope glass shell cooperating of input framework 3 with the input frame gap, according to shown in Figure 1, above-mentioned input framework 3 positive settings and the aperture of in advance visual video data being cut apart the luminous point same number of distribution with computer, establish and import the macropore of framework 3 corresponding same numbers in the output framework 6, the fiber bundle that not isometrical optical fiber 4 compositions are set between input framework 3 and the output framework 6 interconnects with big aperture respectively, one end of not isometrical optical fiber 4 is smaller diameter end cross section 8, the other end be larger diameter end cross section 7 as shown in Figure 2, big, the ratio in smaller diameter end cross section 8 and 7 cross section is between 1.5~2.Every optical fiber 4 two ends are inserted aperture and the macropore imported in framework 3 and the output framework 6 respectively and must be adhesively fixed by bonding agent, and its bonding plane 5 plays firm effect.
According to shown in Figure 3, the not isometrical optic fibre hole that input framework 3 has with the light-emitting pixels correspondent equal is an aperture, and centerline hole all is vertical with screen, whole optic fibre holes formation standard 3:4 rectangles areas of taking a sample, and its diagonal equates with picture tube 1 effective diagonal.
According to shown in Figure 4, the not isometrical optic fibre hole of output framework 6 is a macropore, and centerline hole all is vertical with output face, and the hole in its output framework 6 is chamfered bore, as shown in Figure 5.
The utility model will be combined into matrix for m * n amplifying unit device in length and breadth, non-black gap on the framework 6 of output, occur and isolate TV image amplification right angle screen, its brightness, definition, color saturation, contrast all keep former screen image, and be visual and undistorted.
