Embedded installation is a common installation method that allows two objects to be installed close together to form a whole. It looks simple, beautiful and saves space, making it a popular installation method nowadays.
In the industrial sector, industrial displays offer a variety of installation methods, including snap-on, wall-mounted, cantilevered, desktop, and louvered horizontal types. Equipment manufacturers choose the appropriate installation method based on different scenarios. Among these, embedded installation is more common in scenarios such as electrical equipment, instrumentation, and terminal equipment, as it is a suitable application and aligns with the embedded system paradigm.
Embedded installation is divided into internal and external embedding. Although both are embedded, they have fundamental differences. Internal embedding involves embedding the entire device inside another device, while external embedding, due to its thin outer frame, has the meaning of "inlaying". Therefore, if a distinction must be made between external and internal embedding, then external embedding is inlaying and internal embedding is embedding. Together, they are "embedding".
Choosing between external and internal installation is a question that many engineering designs consider. What factors determine this choice? In addition to the structure of the device itself, it also relates to the adaptability of the touch industrial display to the environment and its compatibility with the application scenario.
There's no rule stating that any type of equipment must use embedded or external displays. Even the same equipment, across different generations, may have altered external designs, or even be modified to meet specific customer requirements. We often see self-service terminals in indoor locations like banks, train stations, and subways using embedded industrial displays, while in indoor locations like airports, we see externally mounted self-service terminals. The same type of application will have different presentations, and the same type of equipment will also have different designs.
Indoor and outdoor environments differ, so will this affect the choice of embedded touch devices?
Currently, common outdoor terminal equipment includes express delivery lockers, self-service retail terminals, and charging piles. The accompanying display devices are mostly embedded. To cope with outdoor wind and rain, the monitor has a protective visor design. Even though many monitors now have an IP65 dust and water resistance rating, this visor helps reduce damage caused by prolonged exposure to sunlight and ultraviolet rays. In ordinary indoor environments, the embedded design is aesthetically pleasing, but in dusty factory environments, the recessed design can cause dust accumulation, making cleaning difficult and reducing touch sensitivity.
The choice between external and internal installations also involves the disassembly and maintenance of the equipment. If the terminal equipment malfunctions, an externally installed device is easier to disassemble; while an internally installed device, which is embedded in the terminal equipment, requires the entire device to be disassembled.
External mounting involves opening holes for installation, while internal mounting involves connecting to the main body of the terminal device as one unit. During installation, both methods can achieve a sealed installation, preventing water and dust ingress.
For applications where the display can be completely blocked or covered, an embedded design is preferable, while an external design is more suitable for applications that need to cope with changes in the external environment.
