Abstract

The utility model relates to an optical gate controllable high luminance optical fiber lattice color screen which is composed of a cold light source, a monochromatic or three primary color board, a controllable optical gate and a control system. The utility model uses the ultra luminance cold light source. Color patterns are formed by optical fiber lattices, and the luminance and the color of each lattice are controlled by the controllable optical gate. The optical fiber lattices are formed by the arrangement of single strand of optical fibers or optical fiber bundles, and the entire display screen is formed by the combination of a plurality of unit screens. The utility model has the advantages of high luminance, complete colors, capability of being manufactured as products, indoor and outdoor splicing and installation and normal use in the daytime.

Description

Optical gate controllable type high-brightness fiber-optic dot matrix color line screen

The utility model relates to a kind of optical fiber dot matrix colorful display screen.

The realization large color screen shows, practical at present have lattice luminous LED display, projection and liquid crystal projecting, a colored optical fiber display screen etc.The colored optical fiber display screen has: as " passive integrated super large screen terminal display " (notification number 2243704), it utilizes LCDs to make image source, with first, last optical fiber battle array, first, last lens battle array alternate combinations, utilize the light transmitting fiber conducting image, utilize twice amplification of lens, to show the jumbotron display effect." no seam large screen television display screen " (notification number 2283951), it is made up of kinescope, video screen, seam filler strip, light transmitting fiber.It is on the giant-screen basis of existing kinescope splicing, utilizes light transmitting fiber, and the pattern on the video screen is sent to the other end, forms a big screen display screen that does not have seam fully.

But the purpose of this utility model aims to provide a kind of high brightness, the full commercialization production of color, is convenient to the oversize colorful display screen that also can normally use daytime is installed.

The implementation of the utility model purpose is, optical gate controllable type high-brightness fiber-optic dot matrix color line screen includes cold light source 1, monochrome or three primary colors plate 2, optical fiber dot matrix screen 4, and optical fiber dot matrix screen is combined by polylith unit screen.Cold light source 1 adopts the above superbright degree cold light source of 5000 lumens, and colour table 2 and 4 of optical fiber dot matrix screens have controlled optical gate 3, and the luminous point on colour table and the controlled optical gate 3 is corresponding one by one with the luminous point of optical fiber dot matrix screen A end, and controlled optical gate is controlled by control system.

The utility model is described in detail in detail with reference to the accompanying drawings.

Fig. 1 the utility model structural representation.

Fig. 2 three primary colors composition that hardens.

By practical study as can be known, realize must possessing following three conditions with the colored type variable giant-screen of optical fiber fabrication high brightness:

1, superbright degree cold light source;

2, the fiber lengths of forming optical fiber dot matrix screen can not be longer than 2m, and short more good more;

3, must control each luminous point of optical fiber dot matrix.

For satisfying above three conditions, the utility model has adopted the above superbright degree cold light source of 5000 lumens, brightness height.Optical fiber dot matrix screen 4 is made up of polylith unit screen, makes the fiber lengths of forming optical fiber dot matrix screen no longer than 2m, and optical loss is limited in the specialized range, also can be easy to commercialization production, be easy to install, particularly outdoor splicing is installed, and any ultra-large type of formation is installed does not have gap dynamic color display screen.

Main is, the utility model allows the corresponding optical fiber dot matrix of each primary colors square formation of three primary colors plate (see figure 2) A hold in colour table 2 and 4 controlled optical gate 3 (see figure 1)s of peace of optical fiber dot matrix screen, makes each luminous point in the optical fiber dot matrix, the color that is every or every bundle optical fiber can be synthetic by three primary colors, and color is complete.And utilize controlled optical gate to control the R of each luminous point, G, B primaries flux, with color and the brightness of regulating each luminous point, realize adjustment to display image brightness, contrast and gray scale.

Controlled optical gate adopts existing optical gate, and it has machinery and two kinds of electronics.Mode to the control of controlled optical gate is also a lot, as adopting the color LCD screen control technology that has been widely used on notebook computer and the liquid crystal projection apparatus, camera shutter etc.

Go into from optical fiber dot matrix screen A end-fire through the light modulated of controlled optical gate, amplify through the optical fiber dot matrix, gone out by the B end-fire, enlargement factor is an optical fiber dot matrix B end points spacing and the ratio of A end points spacing.

The utility model adopts superbright degree cold light source that short fiber is throwed, and makes the pattern of large-size screen monitors end also high-visible by day, and also can normally use daytime.Adopt colour table and the controlled optical gate coloured silk of checking colors to control, color is complete, makes the large-size screen monitors pattern have bright-coloured true color effect true to nature.Utilize the utility model will make colored large-size screen monitors be widely used in outdoor each series advertisements and propaganda.
