Description

Polychrome solid plate display screen

Technical field

The utility model relates to a kind of conduction light-emitting device that is used for sign such as common information pattern symbol, sign, particularly a kind of polychrome solid plate display screen that exchanges the enamel decentralization type electroluminescence.

Background technology

At present, signs such as some common information pattern symbols, sign are used widely, and adopt passive mode luminous or active illuminating to strengthen order mostly and show effect.The passive luminous light projector that also claims shows, generally adopts the light projector effect of reflectorized material such as fluorescent powder by external light source, produces eye-catching effect.But the long afterglow of reflectorized materials such as fluorescent powder decay is very fast, according to not enough or do not have under the situation of light source, can't produce the light projector effect in external light source light, is subjected to the restriction of service condition, is difficult to play its due eye-catching warning function.Active illuminating also claims to conduct electricity luminous, and the optical screen that video screen, light emitting diode or the neon bulb that mainly adopts teletron etc. to show shows etc. by conducting electricity luminous effect, produce eye-catching effect.Higher because of manufacturing costs such as teletron, diode or neon bulb etc. are fragile, apply so influence it.For overcoming above-mentioned shortcoming, the electroluminescent display panel that is used for sign such as common information pattern symbol, sign is come out one after another.The electrode contact of a plurality of transparency electrodes of this electrode contact that utilizes coating electrically conductive luminescent powder substrate and mutual not conducting placed on it, the conduction light-emitting device of composition have advantages such as the service condition of not being subjected to restriction, energy-conservation, long service life.But this based light emitting device is subjected to the influence of its process equipment and manufacture craft etc. bigger in actual production, and its yield rate is lower, not only caused the waste of artificial and material, and panel is of poor quality, inefficiency.

The utility model content

The purpose of this utility model provides a kind of polychrome solid plate display screen, it is not except that being subjected to service condition restriction, energy-conservation, the advantage that the life-span is long of keeping that prior art exists, it is reasonable also to have structure distribution, the panel outward appearance is good, intensity is high, acid-alkali-corrosive-resisting, the visual angle is big, the resolution height significantly improves the characteristics of product quality and eye-catching caution effect.

The purpose of this utility model is achieved in that this device comprises the metal substrate that has contact conductor; luminescent layer; the transparent conductive film layer that has contact conductor; its technical essential is: the bulk metal substrate surface is before high temperature sintering is coated with; back enamel insulating protective layer; at the high resistance medium Titanium of preceding enamel insulating protective layer upper surface high temperature sintering as the reflection horizon; be coated with the luminescent layer of using conduction luminescent powder high temperature sintering to become at the reflection horizon upper surface; the luminescent layer upper surface is provided with transparent conductive film layer; utilize insulated porcelain sleeve to pass luminescent layer the contact conductor of fixing on it; the reflection horizon; metal substrate and preceding; back enamel insulating protective layer is drawn, and the nesa coating laminar surface is covered vitreous enamel cover-coat enamel protective seam together with the exposed end bread of other each layer.

Because the utility model adopts the bulk metal plate to make substrate; and with materials such as enamel and successively sintering process make insulating protective layer, high resistance medium Titanium reflection horizon thereon; the conduction luminescent layer; and processing need show on this foundation plate signs such as common information pattern symbol, sign; so its structure distribution is reasonable; the panel outward appearance is good, intensity is high, acid-alkali-corrosive-resisting; the visual angle is big; the resolution height; can realize not having the seam large tracts of land and show, be applicable to the fierce place of vibration and rugged surroundings such as dust storm invasion and attack, acid and alkali corrosion are arranged.It has also significantly improved the effect of product quality and eye-catching caution except that not being subjected to of keeping that prior art exists service condition restriction, energy-conservation, the advantage that the life-span is long.

Below in conjunction with accompanying drawing the utility model is further described.
