Abstract

The invention discloses an LED lamp sheet capable of displaying a three-dimensional picture, and a processing technology thereof. The processing technology comprises the steps: taking a lamp sheet base body, coating the upper surface of the base body with a photoresist in a spin-coat manner after pretreatment, and carrying out baking and exposure development, wherein a photoetching pattern existson the surface of the base body at the moment; placing the base body in a surface treatment liquid, soaking, spraying ultraviolet fluorescent ink after soaking, and removing the photoresist, wherein asprayed ultraviolet fluorescent pattern exists on the surface of the base body, and an ultraviolet fluorescent ink layer is formed; on the upper surface of the ultraviolet fluorescent ink layer, placing the base body in the surface treatment liquid again, soaking, repeating photoetching and ink spraying steps after soaking, spraying a layer of infrared fluorescent ink on the ultraviolet fluorescent pattern, and forming an infrared fluorescent pattern to obtain an infrared fluorescent ink layer; and spraying conventional printing ink on the lower surface of the base body to obtain a conventional ink pattern. According to the invention, the LED lamp sheet prepared by the method is excellent in pattern durability, relatively good in heat resistance and ethanol resistance, and relatively highin practicability.

Description

technical field [0001] The invention relates to the technical field of light sheets, in particular to an LED light sheet capable of displaying three-dimensional images and a processing technology thereof. Background technique [0002] Advertising light boxes are generally based on blister, acrylic, inkjet cloth, etc., and adopt a box-type hollow structure advertising carrier. It has the characteristics of waterproof and luminous, and is mainly suitable for indoor and outdoor advertising. [0003] With the advancement and development of science and technology, in the era of rapid development of LED advertising light boxes, the use of display screens is also very popular. Most of the existing screens use light sheets to print patterns on the light sheets, and then place the screen on the light source for display. It shows that one light sheet can only print one picture, and the pictures cannot be overlapped and displayed. [0004] For example, the authorized announcement numb...
