Abstract
The utility model discloses a novel super-big digital display component, which overcomes the problems in the prior art that eight sections of LED (light-emitting diode) digital display components are complicate in production process and limit in production size. The novel super-big digital display component comprises a printing circuit board and N LED display tubes, wherein N welding plate groups are arranged on the upper surface of the printing circuit board; the N welding plate groups are arranged in a form of seven sections of display codes plus decimal points; the N LED display tubes are respectively welded on the N welding plate groups; each welding plate group comprises M welding plates; the M welding plates are respectively connected with the corresponding parts in a driving circuit on the lower surface of the printing circuit board through a conductive circuit on the printing circuit board; a driving chip in the driving circuit is welded on the lower surface of the printing circuit board; N is a natural number which is more than or equal to 1; M is a natural number which is more than or equal to 2. The technical digital display size can reach more than 5 inch; the product is simple in operation process and easy to maintain.
Description
Technical field
This utility model relates to a kind of digital display device, particularly relates to a kind of novel super large nixie display part.
Background technology
Along with commercial unit automaticity is more and more higher, the display device application on production line is also more and more extensive.8 sections of LED nixie displaies are the conventional parts in computing machine, instrument field, particularly large-scale nixie display, have been widely used in the fields such as education and instruction, bank stock market, station terminal, informative advertising.Such as at field of industrial production, sometimes need the display size that reaches very large, when large scale is made, there is restriction in traditional charactron technique.And traditional large-scale digital device production technology is comparatively complicated, cost is high and yield rate is low, and traditional charactron technique is in printed board, to play PIN pin, die bond then, and bonding wire then, then semi-manufacture test, then encapsulating baking, end product is tested.Traditional manufacturing procedure is various, has increased cost, therefore develops a kind of technique nixie display simple and with low cost imperative.
Utility model content
The utility model has overcome 8 sections of LED nixie display parts in prior art, complex manufacturing technology, and the conditional problem of manufactured size, provides a kind of ultra-large type, the simple novel super large nixie display part of technique.
Technical solution of the present utility model is, provide a kind of novel super large nixie display part with following structure: contain a printed-wiring board (PWB) and N laser-emitting diode, the upper surface of printed-wiring board (PWB) is provided with N pad group, N pad group is arranged in the form of Seven pieces digital displaying code+radix point, N laser-emitting diode is welded on respectively in N pad group, in each pad group, contain M pad, M pad is connected with each pin in driving circuit on printed-wiring board (PWB) lower surface respectively by the conducting wire on printed-wiring board (PWB), driving chips welding in driving circuit is on the lower surface of printed-wiring board (PWB), N is more than or equal to 1 natural number, and M is more than or equal to 2 natural number.M is 2, or is 3, or is 4.Laser-emitting diode and driving chip are surface mounting component.Laser-emitting diode is 3528 or 2121 micro display devices.Driving chip is 74HC595 or 74HC245.On the upper surface of described printed-wiring board (PWB), be provided with transparent encapsulation material layer.
Compared with prior art, the novel super large nixie display of the utility model part has the following advantages: Surface Mount charactron technique is direct die bond on special wiring board, bonding wire then, and then semi-manufacture test, then puts glue baking, end product test.Compare with traditional charactron technique, the latter is without playing PIN pin, can be after special wiring board direct pasting chip, and unlike traditional handicraft, be connected with driver circuit plate by PIN pin.Digital display size can reach more than 5 cun, compares with traditional charactron, and the fluid sealant consumption of Surface Mount charactron is less, and the product of making is very thin, and thickness can be lower than 0.5cm, and cost of manufacture is cheap.The operating procedure of product is simple, is easy to safeguard.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of the novel super large nixie display of the utility model part;
Fig. 2 is the structural representation of the novel super large nixie display of the utility model part printed-wiring board (PWB).
Embodiment
In accompanying drawing explanation, label 1 is laser-emitting diode, the 2nd, and printed-wiring board (PWB), the 3rd, radix point, the 4th, pad.
Below in conjunction with the drawings and specific embodiments, the novel super large nixie display of the utility model part is described further: as shown in the figure, in design and printing wiring board 2, the two sides, front and back of printed-wiring board (PWB) 2 connects by via hole, one side can the miniature laser-emitting diode 1 of Surface Mount 3528 or 2121, one side can drive chip by Surface Mount, need not play pin pin, can reach operation simple, cost-saving.On the surface of the laser-emitting diode 1 after Surface Mount, be covered with encapsulating material, because laser-emitting diode 1 volume is little, encapsulating material is to adopt the mode of some glue to encapsulate, and not only save material, and the finished product thickness of producing is low.Surface Mount charactron technique can increase on the making volume of display device flexibly than traditional charactron technique, meets the demand of various occasions.
