How to choose high-end rental LED display, China rental led display manufacturer
experts said that high-end led rental display to have 7 technical features: EMC optimization design, automatic correction, box status monitoring, dual-card, current-n+1 power dual backup, quiet operation, intelligent brightness adjustment, low reflective nature.
One:EMC Optimized Design
In the application, the LED rental display needs and a variety of electronic equipment at the same time, in order to avoid each other electromagnetic interference, the leasing screen needs to be optimized for EMC design.
For example: PCB using no sharp barbed wiring design, low interference line mode, multilayer copper shield, high frequency separation, sensitive signal multiple processing technology, more optimized circuit design, such as multiple filter, pure power technology, multiple shielding EMC box structure design, etc., through the above design to solve electromagnetic interference.
What is automatic correction? is to store the correction data on the module, replace the module, receive card, send card without doing any debugging, no need to resend the data, power can be used! Traditional correction technology such as "point-by-step correction", replacement module, receiving card requires professional operation to resend the correction data; Set up a folder to store the corresponding module calibration coefficients, stored in the U disk or mobile hard drive, the user needs to save the module correction coefficient, and record the module number, so that each corresponding; Replace the receiving card or module, you need to re-import the correction factor, such as the replacement module after the import factor will appear patches; If the user loses the correction factor , you cannot enable correction.
With the "Dynamic correction" technology rental screen, the user to replace the module or receive cards without any debugging, change the good; the whole screen is corrected effect, colorless, color block, Huati and so on, just power on the whole screen display normal.
Three, cabinet status monitoring

configuration of the receiving card for the box temperature, humidity, power supply, fan signal line communication status detection and monitoring, so that the on-site staff real-time control of the box running state.
Four, dual-card, current-n+1 power double Backup
As LED display by a large number of boxes, a large number of electronic equipment, and the inevitable failure rate of electronic equipment has been plagued by LED display users. Therefore, when the LED screen part of the electronic devices in the failure, the display can still work is particularly important. Dual dual-Power back-up backup is a high demand environment to ensure the reliability and stability of LED display solutions
. Double receive backup way, one box uses two card. Two receiving cards work at the same time, each other hot backup state, in any way signal failure automatically seamless switch, to ensure that the display work foolproof. In the parallel use of the current-sharing power supply, a n+m-fold method can be used to output larger power.
In the parallel system, each current power supply can share less power according to the power, and when a single power supply is in trouble, other current-sharing power supply can continue to provide power supply to the system and improve the reliability of the system.
Five, silent operation
In some rental screen applications of high-end occasions, such as museums, concerts, press conferences, etc. to the LED display noise requirements, the need to adopt a low noise fan or no fan and low noise power supply, sometimes to achieve this effect, the power part of the higher requirements.
Six. Intelligent Brightness Adjustment
In the performance, the stage and only led rental screen a light source, its display effect will be projected, spotlights, shaking lights and other stage lighting effects.
So high-end rental screen is necessary to install automatic adjustment equipment, will not be affected by the ambient light display screen.
Low reflective nature Because of projection, spotlights, shaking light and other light source, rental screen also need to consider the issue of luminescence. LED display
packaging devices used in full black packaging design, the composite effect of the black PPA material and the epoxy resin makes the light bead face the whole to be black, thus enhances the contrast of the display screen better; the device colloid surface adopts the design of fog surface, avoids the light reflection which is produced by the glue mirror effect, thus effectively reduces the reflective interference, So that screen body screen display more soft and bright.
