As a modern intelligent electronic display device, the service life of full-color LED display screens is affected by many factors. The following are the main reasons for the reduction of the life of full-color LED display screens:

The impact of product temperature on the life of the display screen:

High temperature is the main cause of the light decay of LED display screens and shortens the life of LED display screens. The life of LED display screens is manifested as its light decay, that is, as time goes by, the brightness gradually decreases until it finally goes out. The attenuation of the luminous flux of LED display screens caused by high temperature is irreversible. Here is the knowledge about nit brightness.

Increased temperature will reduce the luminous efficiency of LED display screens, affecting their light effect and color.

The impact of environmental dust on the life of display screen products:

The deposition of dust will affect the heat dissipation of electronic components and equipment, causing the temperature of components to rise rapidly, the thermal stability to decrease, and even leakage, which may cause burning in severe cases. Dust will also absorb moisture, corrode electronic circuits, and cause short circuit failures.

Effect of humidity on product life:

Humid gas can penetrate the packaging materials and the joint surface of components into the interior of IC devices, causing oxidation corrosion and short circuit of internal circuits. Methods to improve the reliability of humid environments include the use of moisture-proof materials, dehumidifiers, protective coating covers, etc. What are the supporting equipment for LED display screens?

Effect of corrosive gases on product life:

Humidity and salty air environments will accelerate the corrosion effect of metal parts and form leakage paths. Insulating materials absorb moisture and can also cause an increase in material volume conductivity and dissipation coefficient.

Effect of electromagnetic radiation on product life:

Radio frequency radiation generally interferes with electronic systems in two ways. One is that the electrical noise interference of the radiation field directly penetrates the system, and the other is introduced through the power supply. Electromagnetic interference is enough to change the value of the CPU program counter PC, causing the microcomputer to mistakenly "jump out" of the executing program.

Effect of vibration on product life:

Electronic equipment is often subjected to environmental shock and vibration during normal use and testing. When the mechanical stress caused by the generated deflection exceeds the allowable working stress of the component parts, this environment can cause physical damage to the components and structural parts. Take you to understand LED chips: technology, applications and development.

The above factors will have an adverse effect on the service life of full-color LED display screens. In order to extend the service life of the display screen, it is necessary to fully consider these factors during the design, use and maintenance process, and take corresponding measures to manage and control them.
