Latest high - reliability LED display design requirements

Date: 2018-07-03
Browse: 51

With the development of LED display technology and the deepening of customer awareness, new customers are increasingly demanding the stability and reliability of LED display. Therefore, in order to meet the requirements, the manufacturer must design a more reliable LED display.



At present, the LED display industry standard "general standard SJ/T11141 LED display, in the industry standard and the electronic measuring instrument reliability test GBll463 2 s to determination of test reliability of LED display, in fact it is difficult to realize the MTBF of no less than 10000 hours of the reliability requirement, more can't meet the requirements of high reliability of LED display screen. In order to make LED display with high reliability, the supporting product materials should be greatly improved, and the design requirements must include heating, reasonable and advanced.



I. supporting product materials


1. LED luminous tube.


LED luminescent tube is the key device of LED electronic display, which should adopt mature and reliable LED products. Product features:


Qualitative good, discrete small.


High ESD index: HBM is greater than 4000V.


Small attenuation: less than 5% for 1000 hours


High pressure resistance: Vr = 10V, Ir<2uA


High brightness, wavelength and Angle consistency.


Good lighting: perfect lighting distribution curve.


Can resist temperature difference, humidity and ultraviolet ray, suitable for outdoor environment.



2. Box body.


The whole use steel plate or aluminum, use the door structure. Pin and guide sleeve are adopted at the top and bottom of the box to ensure accurate positioning between the box body.


The overall protection of the box conforms to IP66 standard. The structure should take heat dissipation into consideration.



3. Switching power supply.


The power supply of the display screen adopts the famous brand switch stabilized voltage power module which has passed the certification. All the switching power supply has passed strict test, screening and aging. To ensure full compliance with international safety and quality certification requirements to meet the long-term stability and reliability of the display screen requirements. Under rated working conditions. Ensure service life over 10 years.



4. Connect the plug-in.


The connector is an important connection device in the system. The high quality connector product should be adopted to ensure the thickness of the pure gold plating layer and keep the best electrical connection performance. Ensure good electrical connection performance in high temperature and high humidity environment.


It can make the system run stably and reliably for a long time.



5. Circuit board.


The circuit board is made of flame retardant epoxy board with reasonable design and layout, and it can meet the requirements of electromagnetic compatibility and circuit stability. The processing factory should choose the products produced by famous manufacturers.



6. Drive IC devices of chip.


The drive circuit adopts the international famous brand constant current drive chip. In large temperature range, high precision constant current output and high reliability can improve the uniformity and reliability of the display significantly. The main materials of the display system shall be certified by CE, FCC, UL and CCC.

First of all, the chemical method is mainly used to form the color of the film by chemical oxidation in a specific solution. However, it is necessary to conduct the reference ratio to ensure the final consistency of the color.Second, the high temperature oxidation method, the workpiece must be kept within the scope of the process, and then it must be directly soaked in a specific good molten salt
