Abstract

The invention provides a graphene electroluminescence dot matrix display panel and a manufacturing method thereof. The graphene electroluminescence dot matrix display panel comprises an upper conductive layer, a transition layer, a lower conductive layer and a protection layer in sequence from top to bottom, wherein a light emitting material is printed on one side, adhered to the transition layer, of the upper conductive layer; the upper conductive layer is a graphene film; a light emitting dot matrix is formed on the surface of the upper conductive layer. According to the graphene electroluminescence dot matrix display panel and the manufacturing method thereof, a patterned display panel can be formed by uniformly coating the upper graphene conductive layer with the light emitting material of a matrix mode. Patterning can be achieved for the graphene electroluminescence dot matrix display panel, the problem that a conventional cold light piece is monotonous in display can be solved, and moreover due to the structure of two light emitting layers, the light emitting brightness of the graphene electroluminescence dot matrix display panel can be improved.

Description

technical field [0001] The invention relates to the technical field of electroluminescent light sources, in particular to a graphene electroluminescent dot matrix display panel and a manufacturing method thereof. Background technique [0002] Electroluminescence is a phenomenon in which electrical energy is converted into light energy under the action of an electric field to make objects glow. Electroluminescent cold light sheets can be used in lighting, display and backlighting in daily life due to their advantages of uniform light emission, low power consumption and high brightness. However, the conductive layer of the electroluminescent luminescent sheet currently on the market is indium tin oxide, which has the disadvantages of being fragile, poor light transmission, and high price. People's pursuit of patterned display. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a...
