The liquid crystal display kit for charging piles generally includes acrylic cover plates (or PC cover plates), sheet metal parts, liquid crystal display screens and other components. Another structure consists of a plastic casing, a liquid crystal display screen and other components. Due to the complex structure of the plastic shell and the high cost of mold opening, it is only limited to standardized varieties with large market capacity. These components are generally assembled into an integrated display kit in a liquid crystal factory for supply.

The electromagnetic protection technology of the charging pile display kit mainly focuses on electromagnetic compatibility (EMC). The core objective is to ensure that the display screen operates stably in the strong electromagnetic interference environment of the charging pile while not generating excessive electromagnetic radiation to the outside.

In the intelligent charging pile equipment, the touch screen (HMI human-machine interface) and the main control board are the two core software and hardware units. The touch screen undertakes interactive functions such as user operation, data display, parameter entry, and fault prompt. The main control board is responsible for core control tasks such as charging strategy execution, circuit control, data collection, and safety protection. The stable communication between the two is the foundation for the safe, reliable, and continuous operation of the charging pile. To address issues such as communication disconnection, program freezing, abnormal data synchronization, and difficulty in detecting hidden faults that occur during long-term operation of equipment, the industry generally adopts the heartbeat packet communication mechanism. As the core technology for link preservation, status self-checking, and abnormal fault tolerance between the touch screen and the main control board, it is the key to ensuring the stable coordination of human-machine interaction and equipment control in charging piles.

Car charging piles are generally outdoors, the light is strong, and they have to withstand severe weather such as wind, sun and rain, so their requirements for display screens are different from thermostats, notebooks, mobile phones, etc. What is the difference between outdoor display and general indoor display? At least the following differences:
