Transparent Cabinet Advertising Machine: Technological Innovation of Modern Advertising and Display
1. Basic concepts and working principles of transparent cabinet advertising machine
1) Transparent cabinet advertising machine (Transparent Display Cabinet) is an innovative display device that combines transparent display technology and digital advertising playback functions, and is an advanced application form of digital signage system. Through special optical design and liquid crystal technology, it enables the screen to display vivid dynamic pictures while maintaining high transparency, achieving the dual display effect of "seeing the real object and the information". This type of equipment usually consists of a transparent LCD screen, a multimedia playback system, a touch interaction module (optional), and a well-designed cabinet. The appearance can be either a traditional display cabinet or a modern simple glass panel.
2) From a technical point of view, the core of the transparent cabinet advertising machine lies in its special LCD panel structure. Unlike ordinary LCD displays, the transparent LCD screen uses two pieces of tempered glass printed with transparent ITO circuits during the production process. After the frame glue is applied on all sides, they are aligned and pressed together. The liquid crystal is poured in the middle and sealed. Finally, a layer of polarizer is attached to the top and bottom of the glass. The key is that the filtering directions of the two layers of polarizers must be perpendicular to each other-if the lower layer filters the light in the X direction, the upper layer must filter the light in the Y direction. This special structure makes the screen highly transparent when it is not powered on, and it can maintain sufficient brightness and color performance when it is powered on to display content.
3) The working mode of the transparent cabinet advertising machine can be divided into two basic states: transparent display mode and normal display mode. In transparent display mode, the screen maintains high transparency (transmittance can reach 15%), and the audience can clearly see the physical products displayed in the cabinet; in normal display mode, the screen presents rich multimedia content like a traditional display. These two modes can be switched with one click of the remote control, providing great flexibility for display design. More advanced products also support regional display control, that is, part of the screen area remains transparent to display the physical object, and the other part plays related advertisements or product information, creating a shocking visual effect of virtual and real combination.
4) From the perspective of system composition, modern transparent cabinet advertising machines usually adopt an integrated design, integrating Android or Windows operating system, multimedia player, network connection module (WiFi/wired), USB interface, etc., and can run independently without an external host. Some high-end models also have built-in PCs, and users can customize hardware configurations according to their needs, avoiding complex wiring problems. The addition of touch function has upgraded the transparent cabinet advertising machine from a passive display device to an interactive experience platform. Users can directly touch the "glass" to query product details, watch demonstration videos or participate in interactive games, which greatly improves the sense of participation and memory.
