Detailed Description

The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the embodiments of the present invention, and should not be construed as limiting the invention.

In one embodiment of the present invention, as shown in fig. 1, there is provided an electronic ink printing process on a paper-plastic material, comprising the steps of:

s100: providing transfer printing paper, printing a light-emitting structure on the transfer printing paper to form a sample wafer, and printing a pattern on the sample wafer;

s200: die cutting the sample except for the pattern;

s300: soaking the sample wafer subjected to die cutting in water, and demolding and separating the sample wafer to form transfer printing paper and a printing layer;

s400: and taking out the printing layer after demoulding, and transferring the printing layer to a paper-plastic material.

According to the electronic ink printing process on the paper-plastic material, the light-emitting structure and the pattern are printed on the transfer printing paper in sequence, the non-pattern structure part on the sample sheet is removed through die cutting, the transfer printing paper is removed through demolding, the printing layer with the light-emitting structure and the pattern is obtained, and the printing layer is transferred to be pasted on the paper-plastic material, so that the electronic ink is printed on the paper-plastic material, the pattern can emit light after the printing layer is electrified, the light-emitting pattern can be changed according to the difference of the light-emitting structure, and various pattern effects are achieved.

In this embodiment, further in the step S100, the light emitting structure includes a base gloss oil layer, a conductive layer, a dielectric layer, a light emitting layer, a transparent electrode layer, and a top gloss oil layer printed on the transfer printing paper in sequence, and the pattern is printed on the top gloss oil layer. The base gloss oil layer can enable transfer printing paper to be more flat and smooth, and a conducting layer printed subsequently has better film-forming property, so that the uniformity of the conducting performance is guaranteed. The shape of the conductive layer is generally the shape of a light-emitting pattern, so that the pattern formed after the conductive layer is electrified to emit light is the pattern to be presented. The dielectric layer can ensure that the whole light-emitting structure has better barrier property, prevent the upper transparent electrode layer from permeating the light-emitting layer and being short-circuited with the conductive layer, and improve the yield of products. The dielectric layer and the light-emitting layer must be sized to cover the pattern formed by the conductive layer to prevent the upper transparent electrode layer from contacting the short circuit from the edge. The transparent electrode layer has good conductivity and good light transmittance, so that the light-emitting structure has a good light-emitting effect. The top gloss oil layer is mainly used for protecting the transparent electrode layer from isolating external water, oxygen and the like, and also preventing the electrode from directly exposing the outside, thereby avoiding potential safety hazards.

Further, the uppermost layer printed on the light emitting structure is a printed pattern, and some printing with colors and patterns can be printed on the uppermost layer, so that the light emitting structure has a very good visual effect even in the case of no light emission.

In this embodiment, further, after printing the base gloss oil layer and the top gloss oil layer, both need to be dried. Specifically, it may be subjected to a drying process using a blower or an oven.

In this embodiment, the conductive layer and the transparent electrode layer are further printed using a conductive ink as a raw material, and after the conductive ink is printed, the conductive ink is cured. Therefore, the conductive layer and the transparent electrode layer after curing treatment can ensure good conductivity and ensure the product quality.

In this embodiment, the conductive ink is further sintered and cured by high temperature or infrared. This may enable curing of the conductive ink.

In the embodiment, the conductive ink is silver paste, and after the silver paste is printed, the conductive ink is baked for 15-25 minutes in an environment at 100-120 ℃. The silver paste is good in guiding performance after being printed and cured as the conductive ink, and can be baked for 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, 21 minutes, 22 minutes, 23 minutes, 24 minutes or 25 minutes in an environment of 100 ℃, 110 ℃ or 120 ℃ to realize curing.

In this embodiment, the dielectric layer is printed by using a dielectric ink as a raw material, and after the dielectric ink is printed, the dielectric ink is heated in an environment at 100 ℃ for 25 to 35 minutes, so that a solvent in the dielectric ink is sufficiently volatilized. Specifically, the dielectric ink may be heated in an environment at 100 ℃ for 25 minutes, 26 minutes, 27 minutes, 28 minutes, 29 minutes, 30 minutes, 31 minutes, 32 minutes, 33 minutes, 34 minutes, or 35 minutes to sufficiently volatilize the solvent in the dielectric ink and achieve curing.

In this embodiment, the luminescent layer is printed by using luminescent ink as a raw material, and after the luminescent ink is printed, the luminescent layer is heated in an environment at 100 ℃ for 25 to 35 minutes to sufficiently volatilize a solvent in the luminescent ink. Specifically, the luminescent ink may be heated in an environment at 100 ℃ for 25 minutes, 26 minutes, 27 minutes, 28 minutes, 29 minutes, 30 minutes, 31 minutes, 32 minutes, 33 minutes, 34 minutes, or 35 minutes to sufficiently volatilize the solvent in the luminescent ink and achieve curing.

In this embodiment, in the step S300, the sample wafer after die cutting is soaked in water for 25 to 35 seconds. Specifically, the sample wafer after die cutting is put into water and soaked for 25 seconds, 26 seconds, 27 seconds, 28 seconds, 29 seconds, 30 seconds, 31 seconds, 32 seconds, 33 seconds, 34 seconds or 35 seconds to be fished out, the transfer printing paper and the printing layer are slightly pushed to be easily separated,

in this embodiment, further, in step S400, after the printing layer is transferred to the paper-plastic material, the moisture and the air bubbles between the printing layer and the paper-plastic material need to be drained. The printing layer can be stably attached to the paper-plastic material, such as a curved paper-plastic material.

The electronic ink printing process on the paper-plastic material provided by the embodiment of the invention has the following advantages:

first, DIY customizable glow effects are achieved.

Secondly, the creative luminous product can be manufactured by the design of the electrode layer pattern and the matching of the DIY layer.

Thirdly, the manufacturing and mass production of the light emitting part device can be realized by the full printing mode.

Fourthly, the limitation that the transparent conductive electrode substrate is required to be printed on originally is broken through, and the printing luminescence can be carried out on any smooth paper-plastic material suitable for printing.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
