Nowadays, LED display has become a part of people‘s life.The display screen industry keeps developing and expanding, but at the same time of the rapid development of this industry, its application technology of safety and fire prevention has been put on the agenda again. The multiple display screen fires in China have sounded the alarm to the entire LED industry.

The fireproof performance of the display screen is mainly related to the two aspects of fireproof raw materials and tank process.So, today, delun sell focuses on the analysis of four factors that affect the fireproofing raw materials of the display screen:

First, the plastic package factor

The plastic kit is an important part of the fireproofing raw material of the display screen. As it is mainly used as the material for the mask bottom of the unit board module, PC+ glass fiber material with flame retardant function is used.It not only has the function of flame retardant, but also can avoid deformation, brittle and cracking when used in high and low temperature and long term.At the same time, it USES good sealing glue, which can effectively prevent the rain from infiltrating into the interior of the external environment, thus avoiding the fire situation caused by short circuit.

Second, wire factor

The larger the unit area of the display screen, the greater the power used, so the electrical stability of the wire is higher.In many wire products, only the use of the requirements of national standards to ensure its safety and stability.These requirements must be met when selecting: first, the core must be a conductive carrier for copper wire.Secondly, the core area tolerance is within the standard range.Finally, the insulation and flame retardant of the wrapped core rubber should be up to standard.

Third, power supply factors

When selecting power supply products, only UL - certified power supply products are the best choice.Because its effective conversion rate can guarantee the safety and stability of the power supply load, it can work well in the hot external environment.

Fourth, external protective structural material factors

It is very important to select the external protective structure material.Due to the low fire rating of the aluminum plastic board of general outdoor display products, it aging rapidly with the high temperature and the cold and hot impact of rain, making it in the humid weather season, rain and dew easily infiltrate into the interior of the screen, easy to cause short circuit of electronic components and cause fire.Therefore, we should choose aluminum plastic plates with higher fire rating in the market, so that they are excellent in fire resistance, strong in fire resistance and flame retardant, as well as strong in oxygen aging performance of special materials for core materials, so as to avoid fire.

Therefore, as a display manufacturer, the quality of products must be guaranteed from the selection of raw materials within the products, so as to avoid the fire phenomenon caused by problems such as poor quality of products.
