Abstract

An interval dot matrix display screen is provided, which is characterized in that: luminescent devices in the screen form a line as pixels according to the standard distance; the line is arranged every integral multiple of the standard distance; the luminescent devices in the screen can also form a row as pixels according to the standard distance and the row is arranged every integral multiple of the standard distance.

Description

The compartment dot matrix display screen

Technical field

The present invention relates to be used for the lattice luminous display technique of the compartment field of display message and advertisement.

Background technology

Electronic display is to press the display device that dot matrix is arranged by luminescent device (as light emitting diode, electric light etc.), by the color of drive signal controlling light emitting device or bright dark, constitutes dynamic picture and text or image.Advantages such as control is ripe, brightness is high because this display screen has, content dynamic change, therefore, on the square, ground such as commercial building, station, airport are widely used in the demonstration of literal or image.

The electronic display of current use is all evenly distributed by dot matrix way by luminescent device, figure or literal are to be made of luminous point, therefore, clearly figure or literal just must use a large amount of luminescent devices, make the display screen cost high all the time, hindered the generally employing of display screen.

Goal of the invention

The dot matrix display screen that the purpose of this invention is to provide a kind of compartment have the dynamic demonstration picture and text identical with the common display screen and the function of image, but cost has only the part of common display screen, and power consumption also reduces because of the minimizing of luminescent device.Therefore purpose of the present invention is exactly to reduce the cost of manufacture and the use cost of display screen, promotes display screen to use more widely in fields such as information issue and advertisings.

The content of invention

Display screen of the present invention is made up of computer control system, driving circuit, screen.It is the determining of displaying contents, the generation of signal and the communication of realization and outer computer etc. that computer control system adopts Single Chip Microcomputer (SCM) system, major function; Driving circuit amplifies the signal that Single Chip Microcomputer (SCM) system produces, and the driven for emitting lights parts are luminous; Screen is a display unit, finishes the Presentation Function of picture and text, and the display mode of the layout of luminophor and picture and text is gordian techniquies of the present invention on the screen.

The technical scheme of screen design is: the luminescent device in the screen is formed row (or row) as pixel by normal pitch, every the integral multiple of normal pitch row (or row) such apart from layout.Suppose that normal separation is S, interval pitch is the integral multiple of normal separation, for example 3S, 4S.Show that picture and text move, utilize the persistence of vision principle to realize showing continuously picture and text.

Be to come displaying contents according to screen row/row at interval when image shows on display screen, therefore a certain instantaneous, image is incomplete.In order to make the image of demonstration complete, employing allows the mode of image motion, according to the persistence of vision principle, add that the observer can have an expection to following piece image according to the movement velocity of image, like this will be persisting a line in certain the row/row image on the retina according to the movement velocity translation of image, therefore, as long as the movement velocity of image is enough fast, the observer will observe the image of continuous motion.The spacing of supposing row/row is N*S, and wherein N is a positive integer, and the speed of image should be higher than N*S/0.1 second so.

Description of drawings

Fig. 1-be the display screen synoptic diagram that every interval 3 row are arranged 1 row

Fig. 2-be the display screen synoptic diagram that every interval 3 row are arranged 1 row

Fig. 3-6-is that every interval 3 row arrange that the display screen of 1 row shows the synoptic diagram of a mobile black triangle

Fig. 7-be that Computer Simulation shows " beautiful   " certain design sketch in a flash

Among the figure: 1-luminophor, 2-abridged luminophor, 3-are shown direction of motion, 4-normal pitch S, 5-luminophor arrangement pitches, the luminous luminophor of 6-of picture and text

Which advantage is the contrast prior art have

1, content innervation

The shown content of display screen is to move by certain speed, around this movement can cause easilier People's attention reaches better effect.

2, save material

Because luminescent device can by several row in the every interval of column or row or a few row row or the delegation that just distribute, therefore, be sent out The use amount of optical device is the part of common display screen, and therefore its driving or control circuit also can reduce.

3, energy savings

Because the consumption of luminescent device and drive controlling device all reduces, therefore also just reduced power consumption, reached the purpose of energy savings.

4, in light weight

The minimizing of various devices will inevitably reduce the weight of display screen.

5, wind resistance

If sky row (row that do not have luminescent device) or null are not sealed, and only the column or row of luminescent device are sealed, will reduce the crosswind area, thus the raising wind loading rating.

Embodiment

The invention will be further described below in conjunction with drawings and Examples:

The display screen synoptic diagram that accompanying drawing 1 is arranged by row for luminophor, the circle 1 that solid line shows among the figure is a luminophor, but the circle 2 that dotted line shows is for there being the luminophor that is omitted in the present invention on common dot matrix display screen, as seen, luminophor is that every interval three row are arranged row, so the actual luminescent device that uses is 1/4 of a common display screen.The direction of motion of the picture and text that arrow 3 expressions among the figure are shown.

Accompanying drawing 2 is a luminophor display screen synoptic diagram by rows, the circle 1 that shows with solid line among the figure is represented luminophor, the circle 2 that with dashed lines shows represents that luminophor is that every interval triplex row is arranged delegation, and the picture and text that arrow 3 expressions among the figure are shown can travel direction.

Accompanying drawing 3-6 arranges that for adopting every interval three row the display screen of row shows the process synoptic diagram of a mobile black triangle.As shown in the figure, establish the normal pitch 4 that need show picture and text and be S, the column pitch 5 that then actual luminophor is arranged is 4S, and 6 is the luminophor of being lighted.Can only show that according to existing luminophor 1/4 of picture and text show, whole picture and text be shown to utilize the persistence of vision principle that the content with three empty row between the luminophor row in 0.1 second all shows.The leg-of-mutton moving direction of arrow 3 expressions among the figure, picture and text are shown a row back and move a normal pitch S along the direction of arrow, the luminophor of screen row have shown that four row afterwards are listed as by next luminophor and have shown, accompanying drawing 3-6 represents the continuous four auspicious of triangle moving process respectively.

Accompanying drawing 7 shows " beautiful   " certain sectional drawing in a flash for Computer Simulation, and bottom line is normal bright luminous point, therefrom embodies columns at interval.The image that instantaneous sectional drawing is represented is also imperfect, but just can see the image of complete motion from the simulated program continuous motion.

Claims
