It can be understood that how to print can be selected according to the printing mode, and the specific printing mode includes screen printing, flexography, gravure printing, inkjet printing, etc., and the printing mode and the process of printing the luminescent paste are not described in detail in the present invention, and the printing scheme described in the present application can be implemented in any printing mode without limitation to the printing substrate.
The luminescent paste is an existing fluorescent ink capable of emitting light after being conducted, the existing fluorescent ink is formed by adding a fluorescent substance into a common ink, preferably, the fluorescent substance in the invention is barium powder and EL electronic powder, when the fluorescent ink is printed on the first ITO substrate 110, the fluorescent ink can be uniformly printed on the first ITO substrate 110 due to the flowing performance of the ink, and meanwhile, due to the drying performance of the ink, the fluorescent ink can be attached to the first ITO substrate 110 to form the luminescent layer. It is understood that such fluorescent inks commonly used in the market can be used in the present invention.
Further, the insulating layer 130 is provided with a hollow pattern, the light emitting layer 120 printed with the light emitting paste is connected to the conductive layer 140 through the hollow pattern, and a region of the light emitting layer 120 connected to the conductive layer 140 is the display region 200. The hollow pattern in the present invention is to connect the light emitting layer 120 and the conductive layer 140; since both the light emitting layer 120 and the ITO can be conductive, an insulating layer 130 is disposed to isolate the ITO from the conductive layer 140 in order to prevent an open circuit. A light emitting sheet is disposed on the conductive layer 140, and the light emitting sheet is disposed at the display area 200 and is used for exciting a fluorescent substance in the fluorescent ink to emit light.
Further, when the light emitting display surface sticker 100 is connected to a circuit board of an electrical appliance and the conductive layer 140 is in a conductive state, the display area 200 on the light emitting layer 120 performs light emitting display according to a preset program. Specifically, when the conductive layer 140 is in a conductive state, a current exists in the light emitting sheet, a voltage exists at two ends of the light emitting sheet, and an electric field generated by the voltage excites the fluorescent substance in the fluorescent ink, that is, converts electric energy into light energy, thereby generating light. The generated light is presented in the display area.

Further, the insulating layer 130 is formed by printing an insulating paste on the light emitting layer 120.
The insulating layer 130 is printed with an insulating paste, which is a commercially available insulating material, and any insulating material that can be printed on the light emitting layer 120 can be used in the present invention.
Further, the conductive layer 140 is formed by back electrode printing.
The current can be collected and conducted by conventional back electrode printing, in particular by conventional screen printing, on the conductive layer 140.
Further, as shown in fig. 2, in a top view of a preferred embodiment of the light emitting display surface sticker 100 provided by the present invention, the hollow pattern is a seven-segment digital display pattern, and an area of the light emitting layer 120 connected to the conductive layer 140 is a seven-segment digital display area 200.
Specifically, the seven-segment digital display area 200 is a display mode of a digital format, i.e., a common counting format. It is understood that the hollow pattern in the present invention is not limited to the seven-segment digital display pattern. Taking the panel of the washing machine as an example, the hollow pattern can also be a series of operation indication display patterns of washing, dewatering and the like on the panel of the original washing machine. Of course, the hollow pattern in the present invention may also be a pattern deformation of the display area on other existing electrical appliance panels, and is not described here by way of example.
Further, a key layer 160 is further disposed between the photo-curing ink layer 150 and the conductive layer 140; when the light emitting display surface sticker 100 is in a state of being connected to a circuit board of an electrical appliance, the key layer 160 is used for receiving user operations and starting a preset program.
As shown in fig. 3 and 4, in another preferred embodiment of the present invention, a key layer 160 is further provided, wherein the key layer 160 is a function area 300, and when a user presses a corresponding function key, a portion of an electrical appliance corresponding to the function key starts to operate. Taking a washing machine as an example, the corresponding function keys are, for example: power, start, pause, etc.
The preset program is a computer program controller, and is used for receiving a corresponding instruction of an electrical appliance host to display, when the light-emitting display surface sticker 100 is powered on, a circuit board of the electrical appliance transmits a display instruction to the light-emitting display surface sticker 100 in a current mode, and the light-emitting display surface sticker 100 displays a corresponding part in the display area 200 according to the display instruction.
Or, the part of the computer program controller related to the function key can be embedded into the conductive layer 140 of the display panel, when the user operates the key on the display panel, the conductive layer 140 on the light-emitting display surface sticker 100 and the related circuit can be opened or closed, and the electrical signal is transmitted to the computer program controller, and the computer program controller controls the corresponding function part of the electrical appliance to execute the operation.
The keys can also be set in a touch control mode, and when a user touches a certain key, a control program of the key is triggered, so that a subsequent series of functional operation processes are executed.
Further, the photo-curable ink layer 150 is formed by printing a photo-curable ink on the conductive layer 140.
Specifically, there are various printing manners for printing the photo-curable ink on the conductive layer 140, which have already been mentioned in the present invention and are not described herein again. The color of the photocurable ink is not limited, and may be any one of the existing color systems. The main function is to print the surface sticker 100 integrally, so that the surface sticker is beautiful and protects the conductive layer 140. It is to be understood that the photo-curable ink is not limited to be printed in a full or only one layer, and characters such as letters and numbers can be printed, so that a user can visually recognize the display area 200 and the functional area 300 on the surface sticker 100.
Further, a second ITO substrate is disposed on a side of the light-emitting display surface sticker 100 facing away from the first ITO substrate 110. The second ITO substrate is prepared in the same way as the first ITO substrate 110, and ITO is also coated on a carrier, and the thickness and material of the carrier can be set according to specific requirements. The second ITO substrate serves to protect the light-emitting display surface sticker 100, so that the light-emitting display surface sticker 100 is waterproof, prevents photo-curable ink from being oxidized, protects against radiation, and the like.
In general, a space is reserved in a panel portion of an electrical appliance for attaching the light emitting display surface sticker 100, and the light emitting display surface sticker 100 is fixed to the electrical appliance in various manners, such as by gluing, adsorbing, and fixing with screws. When a part of the indication pattern on the surface patch 100 needs to be changed, only the surface patch 100 needs to be replaced. For example, if a display pattern for delaying water inflow is added to the washing machine, the surface patch 100 with the pattern is replaced and attached to the washing machine, and then a corresponding command is implanted into a computer program of the washing machine, so that the function of displaying and lighting can be realized. The problem that when the pattern of the panel is changed by a traditional washing machine, the circuit on the panel needs to be changed in a continuous manner is avoided, the material consumption of the circuit board is saved, the cost is saved, and the operation is convenient and fast.
