CN2318680Y - Array light source back- and forth moving imaging display screens - Google Patents

Abstract

The utility model relates to a display device with the spaced rows of arrayed light sources making back and forth movement for imaging, which utilizes the visual persistence principle for human eyes and comprises a light emitting array, a back and forth movement mechanical system, an electronic control device, etc. The utility model is characterized in that a plurality of rows of light emitting arrays composed of light emitting elements are installed on a connecting rod at intervals, and the connecting rod can make back and forth movement. When the light emitting array makes back and forth movement rapidly, the electronic control device carries out real-time control to each light emitting element according to the speed of the back and forth movement, so that pictures and characters which need to be input can be displayed. The utility model does not need a large amount of light emitting elements and can conveniently modify displayed contents, and the cost is lower than that of a usual LED display screen. Besides, the display device has the advantages of light and air penetration, and small integral air resistance, and when installed in the open, the display device is safer than other advertising boards.

Description

The array light source back and forth movement becomes image display screen

The utility model is a kind of display device, relates to a kind ofly utilizing human eye vision to persist effect and obtaining the device of display effect.Being suitable for indoor and outdoor occasions such as various sound attitude large-scale advertisement, shop sign, information board uses.

A large amount of at present LED display of using are to form with array format with light emitting diode.This LED screen is along with area increases, and required light emitting diode quantity becomes geometric series to increase, and cost of manufacture is quite expensive.Introduced a kind of persistence of vision phenomenon of utilizing in " practical electronics digest " second phase nineteen ninety-five ' hand-held electronic information display screen ' translation, with single-row light emitting diode array, under electronic circuit control, handing its quick translation, the beholder just can see the graph text information that a width of cloth is stored in advance.The principle of hand-held electronic information display is very simple, and the data that will be stored among the ROM are read successively by the address exactly, by several diode displaying.The static demonstration only can be seen bright dark variation, cannot see Word message, with the direction parallel fast moving of display (several light emitting diodes nestle up vertical setting of types) along the address increase, reason owing to persistence of vision, the shown information in previous column position also temporarily remains in the visual memory, has just become literal that people can discern, figure.Certainly above-mentionedly brandish single-row light emitting diode array imaging device with hand and only be used for principle of specification, the area of its demonstration, content are all limited, and display quality is also barely satisfactory.The technical scheme that has realized at present adopts multiple row light emitting diode bar shaped array to rotate around circumference under power drive, demonstrates continuous high quality image.But, show that also there is weak point in the circumference rotation scheme of array, one, the circumference rotating machinery is simple in structure but take bigger space, so display device is furnished with more restriction; Its two, the physical size of circumference whirligig can not be too big, so display size can not be too big; Its three, the safety precautions of having relatively high expectations of circumference whirligig.

The purpose of this utility model is that design a kind ofly is fixed on the plane that back and forth movement forms on the connecting rod (or the curved surface on intimate plane) display device by ordered series of numbers point-like luminescent device (each row is made up of several pointolites) with a determining deviation, each luminescent device is by being stored in Data Control in the storer in advance, because of human eye vision persists effect, promptly can be observed complete literal or pattern.

The display device of utilizing human eye vision to persist principle provided by the utility model, by luminous array (each array is made up of several luminophors).When the quick back and forth movement of connecting rod, the luminous array that is fixed in the above is regular to be lighted or extinguishes each luminophor by preset program.That introduces in circuit control mode and the first translation of mentioning of literary composition is similar, and difference only is that single-row light-emitting array will show full content in the translation process in the translation.And each row light emitting array of the utility model only shows the decomposition content that its movement travel is that part of, and round one-period, and data delivery should guarantee the continuous of displaying contents.As long as control the data delivery form well, just can make LED display and can show repertoire.The utility model can be made the standard block structure, and the joint that links to each other with another unit activity connecting rod is all left at the movable rod two ends of each unit, can select several unit to be connected to form long width of cloth display screen as required.Because the utility model adopts space type array layout, has therefore significantly reduced light emitting diode quantity, has reduced cost.Than the circumference whirligig, can reduce the physical size of device greatly, can assemble and be spliced into large-sized display screen.

Describe the structure of the utility model standard block in detail below in conjunction with accompanying drawing.

Among the figure: 1. fixed frame, 2. movable rod, 3. and the linkage connector that joins of another unit, 4. luminous array, the 5. pointolite on the luminous array, 6. back and forth movement mechanical drive system, 7. electronic-controlled installation, 8. Power Supply Assembly.

Luminous as shown in FIG. array 4 is arranged by an element 5 and is formed, and luminous array 4 can be row or some row.Electronic control circuit should be synchronous with the connecting rod shuttle speed, just can see the picture and text that manifested.Change the control program in the electronic circuit, can obtain different literal or pattern.When back and forth movement, just can constitute various curved surfaces if movable rod changes the luminous array that flexible structure (as: driving chain etc.) then fixes on it into, make the picture and text that show more varied and colorful.Because the utility model is to be main body by framework and spaced luminous array, no matter therefore whether move the ventilation and penetrating light that does not influence its behind buildings.Because whole windage I reduces unsafe factor, reduce outdoor erected cost again.

Claims (3)

1. row back and forth movement imaging display device between an array light source, comprise formations such as fixed frame, luminous array, back and forth movement mechanical system, electronic-controlled installation, Power Supply Assembly, it is characterized by the luminous array of said ordered series of numbers, each row is to be made of point light source light-emitting device (as light emitting diode, incandescent lamp, fluorescent light, flashlamp etc.), but it is fixed on the mechanical system of back and forth movement at a certain distance, is equipped with electronic-controlled installation and Power Supply Assembly.When the quick back and forth movement of light emitting array, according to the speed of back and forth movement each luminescent device is carried out control in real time by electronic-controlled installation, just can show the picture and text of pre-input.

2. according to row back and forth movement imaging display device between claim 1 described a kind of array light source, it is characterized by complete unit and become independently cellular system, can show picture and text separately, but several such unit link together again, form bigger display system.

3. according to row back and forth movement imaging display device between claim 1 described a kind of array light source, it is characterized by and change movable rod into luminous array that flexible structure (as: driving chain etc.) then fixes on it and can constitute various curved surfaces when the back and forth movement, make the picture and text that manifest be apparent in the curved surface space.
