The flexible film light-emitting circuit 1 is a novel light-emitting circuit structure which is newly designed for solving the technical problem of the invention. The technology is a special circuit structure which applies the light-emitting principle technology of an organic light-emitting semiconductor and is newly applied. The concrete structure is as follows:
The flexible film light-emitting circuit 1 comprises a substrate film 9, wherein the substrate film 9 is generally a transparent film material or a colored semitransparent film material; a light guide protective layer 10, a luminescent sheet 11, a conductive silver paste layer 12 and a circuit integral protective coating 13 are sequentially arranged on the substrate film 9. The light guiding protective layer 10 is optionally provided, and is generally provided when it is required to protect the printing uniformity of the luminescent material and to restrict the condensing effect of the luminescent material. In this embodiment, the light guiding protective layer 10 is optionally disposed, and the light guiding protective layer is made of unidirectional light-transmitting material, and only light on one side of the light emitting sheet can transmit.
The luminous sheet is made of an organic luminous semiconductor material and is printed on the surface of the base material film in a screen printing mode, and the luminous sheet can be printed on the base material film by a printer by utilizing an electronic ink printing technology.
A layer of conductive silver paste is printed on the entire surface of the light-emitting sheet 11, so as to energize the light-emitting sheet 11, and in this embodiment, the conductive silver paste layer 12 is used, which is naturally sufficient to energize the light-emitting sheet 11. Therefore, the conductive paste is not limited to the conductive silver paste, and the conductive graphite may be used. The conductive silver paste layer is connected with a power supply control box through a printed wire 14.
In order to protect the insulating effect of the whole circuit, a layer of circuit whole protective coating 13 is provided on the whole circuit. At the same time, the printed conductor 14 is also provided with a conductor protection layer 16.
Preferably, the substrate film 9 is a transparent flexible film.
Referring to fig. 4, the flexible thin film light-emitting circuit 1 is connected to a power control box through a flexible circuit board plug 00, the power control box controls whether the light-emitting sheet 11 is electrified according to a switch instruction of a circuit control signal, the light-emitting sheet 11 emits light after being electrified, and a light-emitting area 111 is formed on the light-guiding protective layer 10. The light emitting sheet is connected to a power source through a printed wire 14, and a wire protection layer 16 is provided on the printed wire 14.
Preferably, the wire protective layer 16 has a multi-layered structure for preventing interference, and has an electromagnetic interference release function.
In order to solve the technical problem of the present invention and achieve the technical effect required by the present invention, the touch control circuit of the present invention must be matched with a transparent touch control circuit 3 made of a transparent touch conductive material. As shown in fig. 5. The transparent touch control circuit 3 comprises a touch key 17, a printed wire 14 and a flexible circuit board plug 00, wherein the position of the touch key 17 corresponds to the position of the light guide protection layer 10 of the flexible film light-emitting circuit 1. The transparent touch control circuit 3 is connected with the flexible circuit board plug 00 through the printed wire 14 and then connected with the touch signal control box through the flexible circuit board plug 00.

More preferably, the interlayer 2 is disposed on the flexible thin film light-emitting circuit 1 and/or the transparent thin film touch circuit 3, the interlayer 2 is an electromagnetic interference preventing coating or an electromagnetic interference preventing grid made of a transparent conductive material, and the transparent conductive material is made of a special conductive high polymer or tin antimony oxide. And an electromagnetic interference preventing coating or an electromagnetic interference preventing grid made of the transparent conductive material is coated on one surface, correspondingly attached to the flexible thin film light-emitting circuit 1 and the transparent thin film touch circuit 3.
