Abstract

The utility model provides a large display screen device, which enlarges elemental areas to obtain pictures of large image scale, so that the utility model can provide distant viewing. The utility model is mainly composed of an optical fiber 2, a reflecting surface 4, an input surface 6, an optical fiber bundle 7, a protective sleeve 8, a rear cover 9, an amplifying panel 10, a display surface 5, etc. With the utility model, a display area with dozens of square meters can be obtained. The utility model supports rich colors, and has the advantages of convenient and flexible installation and low cost. The utility model can be used for large outdoor televisions, dynamic signboards, etc.

Description

Pixel enlarges formula large display screen curtain

The utility model relates to a kind of image display device, especially very large-display screen.

Be applied in the giant display of open occasions such as square, station, have huge marketable value in fields such as advertisement, propagandas.Can mainly contain in large tracts of land, long sight distance technique for displaying at present: projection equipment, vacuum teletron array, light-emitting diode display etc., these prior aries are applied to above-mentioned occasion all its restricted factor, for example: the projection type technology, have the particular requirement on the space geometry between its projector and the screen, and its screen is owing to being that " passive luminous " is subject to ambient light interference; The teletron array, its brightness height, picture quality are good, but can't eliminate between the small screen significantly image seam, and relatively heavier; Its chromaticity was lower when light-emitting diode display was used for coloured image; And other new technology as liquid crystal, plasma scope, because its sky high cost, and is not suitable for the demonstration that area reaches several square metres and even tens square metres.

The purpose of this utility model provides a kind of display screen that large-scale image shows of specializing in, and its display area can be selected assembly unit by the user as required between a few square meter to tens square meters, can use and large-scale open-air TV, dynamic billboard etc.

The utility model is achieved in that a kind of very large-display screen, utilize similar medical endoscope principle, gather the light signal of each pixel from a width of cloth small size image, with optical fiber it is conducted to than showing on the large tracts of land respectively, come the area of expanded view picture by the area that enlarges pixel, for watching at a distance.Its principle is seen accompanying drawing 1: from the light signal of optic fibre input end 1 incident, conduct to amplifying head 3 inside through optical fiber 2, reflection on silver-plated parabola 4 is distributed to demonstration on the focussing glass 5.Its area is expanded, (the corresponding reduction of brightness).Make the unit module of n * n pixel with said structure, see accompanying drawing 2: its optic fibre input end is arranged in input face 6, amplifying head is arranged in and amplifies plate 9, and the user can select the module spliced of certain specification and quantity to dress up entire display screen according to the requirement of size and resolution.See accompanying drawing 3: connect image forming apparatus such as projector at input face.

The utility model can reach to following main effect: first: save cost.Amplify plate and adopt the unskilled labor engineering plastics, optical fiber can adopt the organic glass fiber, has avoided using on large tracts of land expensive display material.Second: installing space is flexible.Display screen has less relatively thickness, becomes slab-shaped on the whole, and fibre bundle can cause suitable position and connect imaging device.The 3rd: picture quality is better.Can support abundant colors and higher resolution, and, compare the less interference that is subjected to surround lighting of screen of reflecting type because display surface is luminous internally.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the structure and the schematic diagram of single pixel expansion instrument.

Fig. 2 is n * n the manufacturing cell that pixel integrates.

Fig. 3 is overall package signal and fundamental diagram.

As shown in Figure 1: 2 is light transmitting fiber, from the light signal of a pixel from its input end 1 incident, and penetrate from the other end, arrive amplifying head 3 inner chambers, 3 inner chamber is a paraboloidal, and there is silver-plated reflection horizon 4 on its surface, fiber-optic output is positioned at parabolic focus, the light of outgoing will be distributed on the translucent display surface 5, illuminate display surface internally, and the light-emitting area that is equivalent to pixel is expanded.

As shown in Figure 2: the utility model is made module and mainly is made up of several parts such as input face 6, fibre bundle 7, protective casing 8, bonnet 9, amplification plate 10, display surfaces 5.Input face 6 is rearranged by optic fibre input end.Also can adopt other structures according to different image devices, its line of pixels column position with amplify plate on the arrangement position of parabolic cavity corresponding, middlely connect with optical fiber.

As shown in Figure 3: the user selects the module spliced of certain specification and number to dress up large display screen according to actual needs, is whole input face 13 on image projection to the small screen with picture reproducer 11,12 is camera bellows, and 15 is the frame of giant-screen, and image shows on the whole display surface 14 of giant-screen.

Picture reproducer 11 can be projector, projector, slide projector etc.Or other powerful image device.Ideal situation is to make the small screen 13 connect the digital video equipment with enough brightness, but relevant technologies remains further to be developed.
