Background

The existing zinc sulfide based high field electroluminescent device can only emit light with different colors according to the difference of doping elements, and the color of the emitted light is monotonous. For example, manganese-doped zinc sulfide can emit yellow light, terbium-doped zinc sulfide can emit green light, but the color is adjusted by means of doping, so that patterns cannot be conveniently displayed.

However, such a method may seriously reduce the transmittance and the light emission intensity of the device itself.

As shown in fig. 1 and 2, a groove is then formed in the transparent adhesive film by stamping or etching, and the depth of the groove is less than or equal to the depth of the transparent adhesive film. A first insulating layer 31, a luminescent layer 32 and a conductive layer 33 are sequentially arranged in the groove; wherein the order of the insulating layer and the light emitting layer may be reversed. The first insulating layer 31, the light emitting layer 32, the second insulating layer 311 and the conductive layer 33 may be sequentially disposed in the groove; wherein the thickness of each layer is 5-300 microns, and the width of the groove is 5-2000 microns.

The luminescent layer contains a zinc sulfide-based daylighting material, preferably a material capable of emitting blue light with low wavelength, such as copper-doped zinc oxide.

The conductive layer can be formed by conventional conductive paste such as silver paste and the like after baking.

And a first transparent bonding layer 4 is arranged on one side of the transparent adhesive film, which is far away from the transparent conductive layer.

The other side of the first transparent bonding layer is a second transparent substrate 5; the first transparent substrate and the second transparent substrate may be glass, plastic, film, or the like.

The other side of the second transparent substrate is a second transparent adhesive layer 6.

The quantum dot film 7 is also a quantum dot color conversion film, which is disposed between the third transparent substrate 8 and the second transparent adhesive layer. The quantum dot color conversion film is formed by dispersing different kinds of quantum dots in a polymer, and the different quantum dots can convert blue light emitted by the light emitting layer into red, orange, yellow, green and other colors with long wavelength.
