LCD splicing screen is one of the most versatile and flexible terminal display devices nowadays, and it is also one of the most popular and widely used terminal display devices among users. The LCD splicing screen adopts imported industrial grade or above devices, and all its components are screened for 72 hours of high-temperature aging (able to withstand high temperatures above 70 degrees Celsius).

Tolerance: Reduce the capacitance of components by more than 20%; Switching power supply redundancy of over 30%; The interface circuit allows for reliable operation of component parameters with a power supply voltage of ± 5%; The dynamic characteristics of the components have significant redundancy, ensuring that the system can still operate reliably when the characteristics of the components change.

　　Communication protocols also have various types of fault tolerance:Support continuous refreshing of communication data, and any accidental errors can be quickly corrected; Software also has various fault tolerance measures; Various fault-tolerant measures are adopted for data storage; Real time prompt in case of program misoperation; Using rational judgment to propose illegal data; Hardware supports hot swapping.

　　Electromagnetic compatibility:The power circuit adopts standard computer power supply and shielding measures, and the power noise filter (to stabilize the DC power supply of the switching power supply); The power supply and circuit have good electromagnetic shielding, with a four wire system for separating high current signal ground, low current signal ground, structural safety ground, and power ground, as well as separating analog ground and logic ground as much as possible;

Design specifications for printed circuit boards, including strict regulations on component arrangement, wiring, filtering, etc. Use an oscilloscope to measure the noise dryness on the ground wire of each printed circuit board, with a peak value not exceeding 50mV; The interface circuits within the board, between the boards, and between the chassis have anti-interference design; Strictly separate the on-site wiring, signal lines, and AC power lines (power lines) of the system; Having a good grounding system; In order to improve the reliability of the system, measures are taken to reduce the power supply usage, reserve sufficient margin, and use balanced current drive for external interfaces.
