Background technique

People have experienced the era of print advertising from black and white to color, color to high-definition, and three-dimensional advertising (three-dimensional advertising) is recognized as the next-generation advertising display mode. Because three-dimensional advertising pictures are clear, lifelike, and lifelike, they are very eye-catching, and corporate brand promotion is in-depth. People's hearts are more and more favored by enterprises and advertising companies.

Three-dimensional pictures are generally composed of grating plates and pictures with three-dimensional algorithms. This technology has appeared 10 years ago, but it has not been commercially applied. The reasons are: 1. The quality of grating plates is not good enough. It is PS board or acrylic board. These materials are processed by hot extrusion. During the molding process, due to the uneven heat release, the grating part changes unevenly. As a result, the ridges of the grating are not straight lines, resulting in matching with the picture When the alignment line is not straight, it directly affects people's viewing effect; 2. The cost is high. The cost mentioned here is for the cost of ordinary print advertisements. The cost of three-dimensional pictures mainly depends on four aspects, a. The cost of the board itself, The three-dimensional pictures that can be used for advertising require a strong sense of three-dimensionality. Generally, the material needs to be 1mm-6mm thick, and the material is PS or acrylic. Compared with print advertisements, the cost of the plate itself has increased; If you want to obtain good-quality three-dimensional pictures, you must use a high-precision printer or printing machine with a DPI of at least 300 or even higher. Therefore, the printing cost will increase; c. Processing costs. Whether it is directly printed on the back of the grating material, it is facing the problem of alignment. Once the alignment starts to fit, the material is scrapped if it is found to be skewed (which causes dizziness in human vision), that is, the processing cost increases; d. Labor cost, if in The factory completes the vertical painting processing and then replaces it. Taking the 2mm plate as an example, the weight can be imagined. In addition, the replaced lenticular plate will expand due to thermal expansion and contraction due to environmental temperature changes. The same printing parameters cannot be mass-produced. In summary The cost of three-dimensional advertising posters is huge, generally 10 times, or even dozens of times, that of print advertisements, and once the customer does not advertise on three-dimensional posters, it is difficult to replace ordinary advertisements, so it cannot be used on a large scale.

Contents of the invention

The purpose of the present invention is to solve the problem that three-dimensional advertisements cannot be popularized on a large scale due to factors such as poor grating plate quality and high cost in the process of applying three-dimensional pictures to the advertising industry, and provide flat pictures and three-dimensional pictures for light boxes universal display device.

The universal display device for plane pictures and three-dimensional pictures of the light box according to the present invention comprises a protective glass, a first adhesive layer, a PET base material, a cylindrical lens grating, a focal length glass and a second adhesive layer;

The far display screen side of the protective glass is bonded to one side surface of the PET substrate through the first adhesive layer, and the other side surface of the PET substrate is provided with a cylindrical lens grating;

A plane advertisement picture is sandwiched between the cylindrical lens grating and the near display screen side of the focal length glass; a three-dimensional information picture is arranged on the far display screen side of the focal length glass through the second adhesive layer, and the three-dimensional information picture is located at the focal point of the cylindrical lens grating .

Advantages of the present invention: firstly, the present invention processes the grating film on the PET film base material with silicon back glue through UV transfer process, which is a cold processing process, and the processed grating film has straight ridges and high precision, And the quality of the pitch of the grating film is stable, not affected by the change of ambient temperature, and then the film is attached to the glass surface, the grating film faces inward, when the flat picture is applied, the flat picture is sandwiched between the grating film and the focal length glass; the three-dimensional picture application At the same time, the three-dimensional picture is attached to the focal length glass with a low-viscosity film, and then adjusted conveniently through the up, down, left, and right adjustment knobs. The advanced technology, and the light box manufactured by this technology greatly reduces the cost of three-dimensional advertising, making three-dimensional advertising can be applied on a large scale.
