Abstract

The utility model relates to a cold light numerical code display board, composed of a cold light emitting board, a switch pipe group, a connecting conducting wire group, and a connecting socket. One or a plurality of seven-segment aluminium layers which are of the shape of a Chinese character 'ri' are arranged on the lower current conducting layer of the cold light board; each seven-segment layer of the shape of a Chinese character 'ri' is connected with an outer power supply by the connecting conducting wire through the switch pipe; the switching on and switching off of the switch pipe group are controlled by an interface circuit communicated with the connecting socket, a digital circuit communicated with the interface circuit, or the output end opening of a computer. The utility model is particularly suitable for being used as a large digital display board, and has the advantages of simple structure, convenient manufacture, and low cost.

Description

The digital display board of cold light

The utility model relates to the digital display board of a kind of cold light, belongs to digital display technique field.

Now Chang Yong 8 sections light-emitting diode displays are by a circular point shape and 7 charactrons that the strip light emitting diode is formed, rectangular diode is formed a day word figure, the circular point shape diode is as the radix point effect, so each digital display tube is for being drawn by nine lines (can be eight lines when not wanting radix point), wherein one is its common port, eight (or 7) are its section control end, its public end ground connection of light-emitting diode display for common cathode, its eight (or seven) section control end then shows that with computing machine P1 mouth or number code translator is connected in the circuit by interface circuit, so that data are illustrated by display tube.Therefore this display when showing that as large-scale numeral for example sports ground situation of contest mark shows, just needs with many diode serial connections because the length of rectangular diode itself can not be too big, complex structure so not only, make inconvenience, and the maintenance trouble, expense is also high.

The purpose of this utility model is to provide a kind of cold light simple in structure, that making is easy to maintenance digital display board, can satisfy the required large and small digital display board of various occasions, especially super-huge digital display board.

The purpose of this utility model is to realize like this; the digital display board of a kind of cold light includes the cold light luminous plaque; connect lead; the switching tube group; gang socket; wherein the cold light luminous plaque is served as reasons and is gone up the transparent insulation fender; last transparency conducting layer; luminescent layer; lower conductiving layer; moisture barrier; following insulating protecting plate is formed; the lower conductiving layer that it is characterized in that the cold light luminous plaque be one be provided with at least one seven sections day word aluminium lamination; and its seven periods of word each day; be that an end of one group lead group links with seven sections respectively; the other end of lead group is that the end of output terminal of one group switching tube group is connected with seven respectively; the other end of switching tube group output terminal connects mutually; and be connected with two connection terminals of gang socket respectively with the other end of the joining lead of last conductive layer; and be connected with the alternating current 220V power supply by this socket; the input end of seven switching tubes of each switching tube group and gang socket seven are that one group connection terminal is connected, and link by the decoding interface circuit in this socket and digital circuit or the computer circuits.

The digital display board of the cold light of said structure, when digital circuit or computer circuits have output, make the segmentation combination conducting of switching tube in the switching tube group by interface circuit with input quantity, thereby make the day word on the luminous plaque demonstrate 0～9 numeral, the same with existing digital display pipe, it can form required tens, hundred figure places, thousands digit by a plurality of days words, maybe can adopt radix point and forms the long number that has radix point.

Advantage of the present utility model is: simple in structure, easy to make, especially show for large-scale numeral, it can remedy the deficiency of former digital display plate, and price is also cheap far beyond original digital display plate, but also has luminous flicker free, the visual angle is big, and visibility is far away, advantages such as long service life.

Come the utility model is further narrated with drawings and Examples below:

Description of drawings:

Fig. 1 is the one-piece construction synoptic diagram of the digital display board of cold light.

Fig. 2 one has the circuit connection diagram of the digital display board of cold light of two figure places.

By Fig. 1, shown in 2 as seen, the digital display board of cold light is by cold light luminous plaque 1, switching tube group 2, gang socket 3 be connected lead 4 and form, when the display digit in the cold light luminous plaque is two figure places, seven switching tubes are that one group switching tube group has two groups, in cold light luminous plaque 1, last conductive layer has the terminals of lead joining with it and gang socket 3 to link, lower conductiving layer have two groups totally 14 leads draw, they are divided into two groups, every group seven, end with two groups of output end of switching tube links respectively, the other end of switching tube output terminal connects the back mutually and becomes a lead, link connection terminal (1) with the connection terminal (2) of gang socket 3, (2) link with～220V power supply; The connection terminal of gang socket 3 (5)～(11), (13)～(19) link with an end of the input end of switching tube respectively, the other end ground connection of the input end of switching tube, and two above-mentioned set of connections terminal (5)～(11), (13)～(19) link by socket 3 and digit translation interface circuit.

In an embodiment, switching tube group in the said structure and gang socket can consist of one with the cold light luminous plaque, also can be respectively and be provided with, it is more compact to form integrative-structure for small-sized cold light digital display board, it is also convenient to use, but for the large cold light digital display board, for easy to maintenance, switching tube group and gang socket and display board branch are arranged then better.
