In order to implement the aim, the utility model provides a semi-dynamic vacuum fluorescent displaying device, comprising: an outer housing with vacuum space mainly consists of a panel glass and a base plate; a cathode is used to emit electron when voltage is exerted; an anode which is applied with fluorescent substance is used to respond to the presumptive pattern of electric displaying which is emitted by the cathode when voltage is exerted; an electric controlling device is used to produce electric field, to accelerate and control the electron which is emitted by the cathode, the electric controlling device is arranged on the place corresponding to the part of displaying digit and complex pattern in the anode.
Description
Technical field
The utility model relates to a kind of vacuum fluorescent display.
Background technology
By there being non-grid to classify, existing vacuum fluorescent display can be divided into two classes: one, such vacuum fluorescent display mainly is made up of negative electrode, grid, anode, is referred to as the dynamic vacuum fluorescence display.Negative electrode is under the situation of energising, and the electronics from cathode emission goes out through the control of grid and anode, clocklike bangs and swashs light-emitting phosphor, and it is more that such structure can satisfy the display message amount, needs the little demand of small product size again.Two, such vacuum fluorescent display mainly is made up of negative electrode and anode, is referred to as static Fluorescent Vacuum Display.Under the situation of cathodal closing, realize showing that it is bigger that such structure is fit to character display, the demand that function is less by the gating anode voltage.
But, will show numeral and complex pattern when the part occurring, and the character that most of zone shows is very big, and when simple,, aperture plates is installed all on luminous element as using the structure of dynamic vacuum fluorescence display, will increase cost; As use static vacuum display device structure, the local wiring difficulty then can occur maybe can't connect up, in particular, leading foot is too many when showing numeral and complex pattern, cause difficult wiring maybe can't arrange the leading foot position, under the situation that can connect up, require wiring board that big installation site is provided, be unfavorable for saving cost, the reason that causes above-mentioned shortcoming is that its working method is the corresponding pattern of a leading foot, in the time of will showing numeral and complex pattern in the part by the decision of the operation principle of static vacuum fluorescent display, can cause local leading foot too many, can't connect up.
Summary of the invention
The purpose of this utility model is the advantage in conjunction with above-mentioned two kinds of displays, use the structure of dynamic vacuum fluorescence display in the part of static fluorescence display, solving static vacuum fluorescent display need show numeral and during complex pattern, the problem of difficult wiring occur.
For realizing said purpose, the utility model provides a kind of half dynamic vacuum fluorescence display, and this half dynamic vacuum fluorescence display comprises:
The main shell of forming by face glass and substrate with vacuum space;
Negative electrode, emitting electrons when being used to be applied in voltage;
Be coated with the anode of fluorophor, when being used to be applied in positive voltage, the electronics of response cathode emission shows predetermined pattern;
Electronic-controlled installation is used to produce electric field, and the target electrons emitted is quickened and control, described electronic-controlled installation be arranged on described anode in show the corresponding position of part of numeral and complex pattern.
In the above-mentioned half dynamic vacuum fluorescence display:
Described electronic-controlled installation is a grid, and described grid can be installed between described face glass and the described negative electrode, and it is applied negative voltage, produces to repel electric field; Also can be installed between described substrate and the described negative electrode, it is applied positive voltage, produce the attraction electric field.
Described electronic-controlled installation is a transparent conductive material layer, is installed between described face glass and the described negative electrode, and it is applied negative voltage, produces to repel electric field.
There is difficult wiring in static vacuum fluorescent display when needs show numeral and complex pattern.The utility model shows the position of numeral and complex pattern at needs, be provided with electronic-controlled installation accordingly, promptly grid or transparent conductive material layer are installed in this position, on grid or transparent conductive material layer, anode, apply pulse voltage, make fluorophor luminous on request, can reduce a large amount of leading foots, reduce the wiring difficulty, for product arranges that more multiword symbol information provides the space.
Description of drawings
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is the profile of the utility model embodiment.
In the drawings, the connotation of each Reference numeral is:
1 local aperture plate 2 face glasss 3 transparent shielding conductive layers
4 negative electrodes, 5 grids, 6 anodes
7 substrates
Embodiment
Below in conjunction with accompanying drawing the utility model is done further introduction in detail.
The utility model is quoted the control mode of Dynamic Fluorescence display at the position that will show numeral and complex pattern, promptly aperture plate is installed, is carried out the control of three utmost points, minimizing leading foot that like this can be a large amount of at this position, referring to Fig. 1, as will show 3 " 8 " time, static fluorescence display needs 21 leading foots, after changing the control of three utmost points into, local aperture plate 1 promptly is set thereon, leading foot only needs 11 leading foot (not shown), will save 10 leading foots, reduces the difficulty of wiring greatly.
Referring to Fig. 2, shell of the present utility model mainly is made up of face glass 2, substrate 7 and the sealing of side glass (not shown).The anode 6 that is coated with fluorophor is installed on the substrate 7, on anode 6, applies positive voltage.
Electronic-controlled installation can be grid 5, it can be set in place between negative electrode 4 and anode 6, also can be between face glass 2 and negative electrode 4 (not shown), and corresponding to the part that needs to show numeral and complex pattern on the anode 6.When grid 5 is between negative electrode 4 and anode 6, grid 5 is applied positive voltage, negative electrode 4 electrons emitted are subjected to the attraction from grid 5, are accelerated to arrive anode 6; In the time of between face glass 2 and negative electrode 4, grid 5 is applied negative voltage, negative electrode 4 electrons emitted are subjected to the repulsive force from grid 5, are accelerated to arrive anode 6.In Fig. 2, grid 5 is arranged on the substrate 7, and between negative electrode 4 and anode 6.
Electronic-controlled installation can also be the transparent conductive material layer (not shown), and it is arranged on the inner surface of face glass 2 and is used as electrode, and it is applied in negative voltage, produces repulsive force, electrons emitted is accelerated arrives anode 6.
Face glass also is provided with a transparent shielding conductive layer 3 for 2 times, is used to shield the electronic jamming that comes from the external world.
Technological process is identical with present vacuum fluorescent display substantially for the utility model, and difference is mainly manufactured at anode substrate, and is specific as follows:
Though the utility model discloses as above with preferred embodiment, be not in order to limit the scope that the utility model is implemented.Any those of ordinary skill in the art, in not breaking away from spirit and scope of the present utility model, when doing a little improvement and variation, promptly all equivalent variations of doing according to the utility model should be the utility model claim and contain.
