LED display rental when the choice of high-end products, high-end LED rental display to have about 7 technical features: EMC optimization design, automatic calibration, box status monitoring, dual card, current N + 1 power dual backup, Running, intelligent brightness adjustment, low reflectivity.
First, EMC optimization design
In the application, LED rental display and a variety of electronic devices need to run at the same time, in order to avoid mutual electromagnetic interference, the need for rental screen EMC optimization design. For example: PCB with no spire wiring design, low interference alignment, multi-layer copper shield, high and low frequency separation, sensitive signal multiple processing technology; more optimized circuit design, such as multiple filtering, pure power technology; Shielding EMC box structure design, etc., through the above design to solve electromagnetic interference.
Second, automatic correction
What is "automatic calibration"? Is the calibration data stored in the module, replace the module, receive card, send card without any debugging, no need to re-send data, power can be used!
The traditional "point by point correction" and other correction technology, replace the module, the receiver card requires professional operation to re-send correction data; need to give each module number, the establishment of the corresponding folder storage module correction factor, stored in the U disk or In the mobile hard disk, the user needs to save the module correction coefficient separately, and record the module number, so that one to one correspondence; replace the receiving card or module need to re-import the correction factor, such as the replacement module will not appear after the introduction of the coefficient Block patch; if the user once the correction coefficient is lost, the correction can not be enabled.
With the "dynamic correction" technology rental screen, the user to replace the module or receiver card without any debugging, for the like; the whole screen are corrected results, no color, color, Huaping and other issues, just power On the screen display normal.
Third, the box state monitoring
High-end rental screen configuration of the receiver card can be on the box temperature, humidity, power, fan signal line communication status detection and monitoring, so that the scene staff real-time control box running.
Four, dual card, current flow N + 1 power dual backup
As the LED display by a large number of boxes, a large number of electronic equipment, and electronic equipment inevitable failure rate has been plagued by LED display users. Therefore, when the LED screen part of the electronic device in the event of failure, the display is still working properly is particularly important.
Dual card, dual power backup function backup is for high demand to ensure that the LED display reliability and stability of the solution.
Double receive backup mode, a box using two receiving cards. Two receiver cards work at the same time, mutual hot standby state, in any way the signal failure automatically seamless switch to ensure that the display work foolproof.
In parallel use of current sharing, can be used N + m times the method to output a larger power. In parallel system, each current-sharing power supply can be divided by power share less power, when a single power supply failure caused by failure, other current-sharing power supply can continue to provide power to the system work to improve system reliability.
Five, quiet operation
In some rental screen applications of high-end occasions, such as museums, concerts, press conferences on the LED display noise requirements, the need for low noise fan or fanless and low noise power, and sometimes to achieve this effect, Will put a higher demand for the power part.
Six, intelligent brightness adjustment
In the show, the stage and only LED rental screen a light source, the display will inevitably be projected, spotlights, moving lights and other stage lighting effects. So high-end rental screen is necessary to install automatically adapt to the light adjustment equipment, not because of ambient light and affect the display screen.
Seven, low reflective
As the projection, spotlights, moving lights and other light sources exist, the rental screen should also consider the issue of light. LED display package device using a full black body package design, by the black PPA material and epoxy resin integrated effect, so that the overall positive side of the lamp beads, so as to better improve the display contrast; device colloidal surface using matte design, To avoid the effect of the mirror produced by the light reflection, which effectively reduce the reflective interference, so that the screen screen display more soft and bright.
