Abstract
Inside the cylinder with retaining ring at the projection exit of common projection TV set, are set a projection lens and a plane mirror, and the projection exit is connected to display screen comprising optical-fibre panel, optical-fibre image-transmitting bundle and casing. High-brightness image is projected onto the small end face of optical-fibre image-transmitting bundle and transmitted to large end face. The optical-fibre panel has same material as optical fibre and inclined end face so that it enlarges the image. The flat TV set has large display area, thin display screen, high brightness and low production cost.
Description
The present invention relates to a kind of dull and stereotyped large-scale tv machine.
Existing dull and stereotyped large-scale tv machine mainly contains two kinds of liquid crystal flat panel display and plasma panel displays.The former is restricted because of the monolithic area, so need the multi-disc combination, constitutes large-screen, influences the effect of rating; Latter's cost is very high, is difficult to promote.
The object of the present invention is to provide a kind of being easy to make, cost is low has flat TV set to the projection TV set zoom function.
The present invention is made up of projection TV set, it is characterized in that: a projection lens 21 and a level crossing 23 are set in the cylinder that has back-up ring 20 of general projection television machine 22 projection export departments, and wherein level crossing 20 is arranged between back-up ring 24 and the projection lens 21; This device comprises a display screen with enlarged image function, and it is by fibre faceplate 1, and optical fiber image transmission beam 7 and shell 6 are formed; Optical fiber image transmission beam 7 is made up of optical fiber 4, and two end face one ends of optical fiber 4 tilt, and an end is vertical, and wherein inclined end face is formed the large end face 3 of optical fiber image transmission beam 7, and perpendicular end surface is formed the small end face 10 of optical fiber image transmission beam 7, and small end face 10 is the input face of display screen; Two end faces 2 in the fibre faceplate 1 and 11 all tilt, and the inclination angle is more than or equal to the critical angle of the optical fiber in the fibre faceplate 1; End face 2 sandings are the output face of display screen, end face 11 polishings; End face 11 and end face 3 are coupled, and the arrangement position of the fiber end face in the fiber end face in the end face 11 and the end face 3 is corresponding one by one, and the fiber core material in the fibre faceplate 1 is identical with stamen material in the optical fiber image transmission beam 7; Have a sleeve pipe 5 to be fastened on the optical fiber image transmission beam 7, its top is toroidal, and the bottom is taper, is stuck with the bellmouth of shell 6 bottoms; The back side of the big termination of the inboard of shell 6 and optical fiber image transmission beam 7 is glued together with binding agent 12; The bottom that is fastened on the sleeve pipe 9 of optical fiber image transmission beam 7 ends flushes with small end face 10, and protectiveness overcoat 8 is arranged outside the optical fiber image transmission beam 7; Fill light absorbing material 13, the major axis of the oval end face 14 that this horizontal spacing equals to tilt between the horizontal spacing between the inclined end face of the large end face 3 of optical fiber 4; Extend the optical fiber 4 of the big head bottom part of optical fiber image transmission beam 7, be attached to big head bottom part and disturb bunchy suddenly; On the big head bottom part light absorbing material several equally spaced arc-like sheets 15 are arranged, this arc-like sheet 15 sticks on the light absorbing material of big head bottom part.
Above-mentioned fibre faceplate 1 also can be made up of the grid that inner surface is aluminized, described grid can be glass or plastics, each checkerwork cell that constitutes grid is square, one group of inclination of its inner surface, one group vertical, grid be docking together through the large end face 3 of sanding, outside the aluminizing of grid 17 faces, checkerwork cell in the grid is corresponding one by one with inclined ellipse shape end face 14 in the large end face 3, and oval end face 14 is between the aluminium plated surface of two inclinations in the checkerwork cell, covers a scatter plate 16 in the outside of grid.
Advantages such as the present invention adopts the mode of display screen with enlarged image function and projection TV set combination, finishes the flat panel display of television image, and it is unrestricted to have a display area, and thickness of displays is thinner, and high brightness shows and cost is low, making is simple.

Image amplification principle of the present invention is the small end face of high-brghtness picture images projection at optical fiber image transmission beam, be on the input face of display screen, import on the large end face through optical fiber image transmission beam, the fiber core material intrafascicular owing to fiber core material in the fibre faceplate and fibre optic image transmission is identical, again since the end face of fibre faceplate be tilt and the inclination angle more than or equal to the critical angle of optical fiber, so image light enters fibre faceplate, be that the output face of display screen scatters out from the frosted end face of fibre faceplate at last, thereby image is exaggerated.If replace fibre faceplate with grid, the sanding of the large end face of optical fiber image transmission beam palpus is that the image light that input face transmits is scattered at large end face from small end figure like this, scatter out from scatter plate after the checkerwork cell reflection of aluminizing, thereby image is exaggerated.
The optical fiber monolithic layer of optical fiber image transmission beam sees that Fig. 8,18,19 is the gummed part, makes the light absorbing material plate by the shape of this monolithic layer gummed part 18, and its thickness equals the major axis of the oval end face of slant optical fiber.With closing plate clamp the gummed part 18 of optical fiber monolithic layer and light absorbing material plate a slice a slice gummed that overlapping, and add certain pressure, it is cured under stationary temperature, makes the big end portion of optical fiber image transmission beam after at last it being ground, polishes.Under big head bottom part light absorbing material plate, be stained with equally spaced arc-like sheet.The optical fiber monolithic layer is not glued together part and is disturbed suddenly, is attached on the corresponding arc-like sheet.Optical fiber monolithic layer gummed part 19 becomes the small end head of optical fiber image transmission beam after gluing together, closing sheet, curing, cutting, grinding and polishing.The arc-like sheet effect is to avoid optical fiber 4 undue crooked, prevents optical fiber 4 exposures or fractures.
Fibre faceplate is made the optical fiber monolithic layer of end slope shown in Figure 9 earlier, and the inclination angle of end face is more than or equal to the critical angle of optical fiber.This monolithic layer entire body gummed.Make the light absorbing material plate by the shape of optical fiber monolithic layer, its thickness equals the poor of the major axis of oval end face of slant optical fiber and fibre diameter.With closing plate clamp optical fiber monolithic layer and light absorbing material plate a slice a slice gummed that overlapping.And add certain pressure, it is cured under stationary temperature, form fiber bundle, at last fiber bundle is cut, make cut surface be parallel to the end face of fiber bundle, again the fibre faceplate that cuts down is carried out grinding and polishing, a mirror polish wherein, one side sanding.
