Abstract
The utility model discloses a novel plastic film electroluminescent screen. The utility model is characterized in that a PVC transparent plastic film insulating layer is arranged between a pattern layer and a transparent conducting layer; an insulating layer and a luminescent layer are arranged between the transparent conducting layer and a vacuum evaporation conducting layer; the outer side of the vacuum evaporation conducting layer is provided with a PVC transparent plastic film insulating layer for installation; the transparent conducting layer and the vacuum evaporation conducting layer are respectively connected with an external power conducting strip. The utility model is thermoformed after the vacuum in the utility model is sucked by a vacuum hot press. The utility model has the advantages of low cost, electricity saving in use, clear figures and characters, no noise, shock resistance, and possibility to bend. The utility model is applied to signboards, fingerposts, automobile number plates, etc.
Description
The utility model relates to a kind of novel plastic thin-film electroluminescent screen.Be applicable to sign board, signpost, nameplate and license plate etc.
The luminescent screen that uses has vitrified enamel optical screen and glass luminescent screen at present.Vitrified enamel optical screen easy fracture is afraid of collision, damages easily; The vitrified enamel optical screen needs just can make, consume a large amount of electric energy through the repeated multiple times sintering, and cost is higher, and the vitrified enamel optical screen is made pole plate with its iron plate, weight is big, iron plate itself is charged in the use, so need add the insulation course protection, enamel screen can not crookedly be used and be restricted in addition.Collision is afraid of in the easy embrittlement of glass luminescent screen, and weight is big, the moisture-proof extreme difference, and for moisture proof also need add drying agent, glass luminescent screen manufacturing and encapsulation difficulty in addition.
The purpose of this utility model is to design a kind of novel plastic thin-film electroluminescent screen of being made up of graph layer, transparency conducting layer, transparent plastic film insulation course, luminescent layer and vacuum evaporation conductive layer for overcoming above-mentioned weak point; Save electric energy, pictograph is clear.
The utility model content, between the graph layer of novel plastic thin-film electroluminescent screen and transparency conducting layer, be provided with PVC transparent plastic film insulation course, be provided with insulation course and luminescent layer between transparency conducting layer and the vacuum evaporation conductive layer, vacuum evaporation conductive layer outside is provided with can be for the PVC transparent plastic film insulation course that usefulness is installed; Transparency conducting layer and vacuum evaporation conductive layer respectively are connected to the external power supply conducting strip.
Transparency conducting layer and external power supply conducting strip, vacuum evaporation conductive layer and the external power supply conducting strip of novel plastic thin-film electroluminescent screen are all bonded together by conductive silver paste, and the inside that figure or literal or figure and literal can be printed on graph layer also can be printed on the outside; Can make light part for luminescent screen to figure or literal or figure and literal also can make and be dark portion.
The utility model advantage:
(1) great advantage of novel plastic thin-film electroluminescent screen is power saving, every square metre power consumption 80W, and brightness lamp box type billboard every square metre power consumption 200W suitable with it.
(2) brightness is 30cd/m
2, high-visible with interior pictograph at 30m, good brightness light is soft.
(3) can not produce any electromagnetic induction signal in the work, so noiseless.
(4) each layer of the present utility model is plastics, so in light weight flexible, anti-vibration is shock-resistant, and the life-span is long.
(5) array packages is hot-forming after being vacuumized by the vacuum hotpressing machine according to the order of sequence for each layer of the utility model, makes easily, and cost is low.
(6) simple installation, only needing to coat adhesive sticker in outer field PVC plastic insulating layer outside can bonding installation.
Description of drawings:
Fig. 1 is the utility model synoptic diagram.
Fig. 2 is the A-A cut-open view of Fig. 1.
Further specify the utility model embodiment below in conjunction with accompanying drawing, the luminescent screen body of novel plastic thin-film electroluminescent screen is drawn two external power supply conducting strips 2,3 for 1 li, is provided with PVC transparent plastic film insulation course 5 between the graph layer 4 of luminescent screen body and transparency conducting layer 6; Be provided with insulation course 7 and luminescent layer 8 between the another side of transparency conducting layer and the vacuum evaporation conductive layer 9, vacuum evaporation conductive layer peripheral hardware one deck can be for the PVC transparent plastic film insulation course 10 that usefulness is installed; Transparency conducting layer 6 is bonding with external power supply conducting strip 2 usefulness conductive silver pastes, and vacuum evaporation conductive layer 9 also uses conductive silver paste bonding with external power supply conducting strip 3.Having encapsulated cause vacuum hotpressing machine at last vacuumizes back hot-forming.Novel plastic thin-film electroluminescent screen principle of work is by after transparency conducting layer 6 that is contained in the luminescent layer two sides and 9 energisings of vacuum evaporation conductive layer, produces AC field, impels the luminescent layer that scribbles fluorescent powder to produce light.The main effect of PVC transparent plastic film insulation course 5 is protection transparency conducting layers and plays insulating effect that the effect of insulation course 7 is to prevent transparency conducting layer 6 and luminescent layer 5 short circuits; PVC transparent plastic film insulation course 10 is protection vacuum evaporation conductive layers and plays insulating effect, also is used for installing the utility model.Word among Fig. 1 " PVC " can be made as light, then shields the end for dark-coloured, also " PVC " can be made as dead color, and it is bright then shielding the end.Contrast is clearly demarcated, so that literal or figure seem is very clear.
