Three-dimensional printing method and three-dimensional display panel

Abstract

The invention provides a three-dimensional printing method and a three-dimensional display panel. The three-dimensional display panel comprises a transparent panel substrate, wherein the transparent panel substrate is provided with a first surface and a second surface; a grating layer film is formed on the first surface of the transparent panel substrate through silk screening; a depth layer film and a color layer film are sequentially printed on the second surface of the transparent panel substrate; and the depth layer film is stagged away from the grating layer film by a certain angle. The three-dimensional printing method comprises the following steps of: (1) forming the grating layer film on the first surface of the transparent panel substrate through silk screening and curing the grating layer film through ultraviolet light; (2) performing texture layering on patterns to be printed to obtain a color layer and a depth layer; (3) forming the depth layer film on the second surface of the transparent panel substrate through silk screening; and during silk screening, staggering the depth layer film away from the grating layer film by a certain angle, and then performing heating and curing; and (4) printing the color layer film and heating and curing the the color layer film. The three-dimensional printing method provided by the invention is capable of realizing the patterns with 3D three-dimensional effect on the transparent panel substrate, so that the layered panel with the patterns with 3D three-dimensional effect and depth of field can be fabricated.

[0004] Nowadays, a variety of patterns are printed on various home appliances to increase the aesthetic feeling of the design, satisfying people's pursuit of higher and higher beauty in life, different patterns also reflect the user's taste and personality, and can also reflect different brands Therefore, in the pursuit of multifunctional and humanized home appliances, there is also a higher demand for various panel pattern designs and printing technologies. The most commonly used printing technology on home appliance panels is screen printing technology (referred to as silk screen printing) technology), but at the present stage, silk screen printing technology can only reflect the light and shade of the pattern and the difference in unevenness through the depth of the ink, and cannot achieve a comprehensive and multi-directional display of the level and depth of the pattern, and cannot present a 3D stereoscopic effect. Therefore, the current The pattern obtained by silk screen printing technology is essentially flat and lacks three-dimensionality.
