How to choose high-end rental LED displays when you are looking for LED displays? There are following 7 technical features. Let us go ahead.
7 technical features of high-end rental LED displays

Automatic correction
What is “automatic calibration”? It means that the calibration data is stored on the LED display module. There is no need to do any debugging when replacing the module, receiving card, or sending card. There is no need to resend the data. It can be used after powering on.
With traditional calibration technologies such as “point-by-point calibration”, replacing modules and receiving cards requires professionals to resend the calibration data; each module needs to be numbered, and a folder needs to be created to store the correction coefficient of the corresponding module, which is stored in a USB flash drive or In the mobile hard disk, the user needs to save the module correction coefficients separately and record the module numbers so that they correspond one to one.
After replacing the receiving LED card or LED display module, the correction coefficients need to be re-imported. If the coefficients are not imported after replacing the module, a color will appear. If the user loses the correction coefficients, the correction cannot be enabled.
Top rental LED display manufacturers use “dynamic correction” technology, users do not need to do any debugging after replacing the LED display module or receiving LED card, just replace it; the entire LED screen has the corrected effect, without problems such as color aberration, color blocks, screen blur, etc.
LED Cabinet status monitoring
The receiving LED card configured with the high-end rental LED screen can detect and monitor the box temperature, humidity, power supply, and fan signal line communication status, allowing on-site staff to control the box operating status in real time.
Dual cards, current sharing N+1 power supply dual backup
Since the LED display consists of a large number of cabinets and a large number of electronic equipment, the inevitable failure rate of LED displays. Therefore, when some electronic components on the LED screen fail, it is particularly important that the LED screen can still work normally.
Dual-SIM and dual-power backup function backup is a solution to ensure the reliability and stability of Rental LED displays in high-demand environments.
Dual receiving backup mode, one cabinet uses two receiving cards. The two receiving LED cards work at the same time, in mutual hot backup status, and automatically and seamlessly switch when any signal fails, ensuring that the rental LED screen works foolproof.
When the current sharing power supply is used in parallel, the method of N+m times can be used to output larger power. In a parallel system, each current-sharing power supply can share less power according to its power share. When a single power supply encounters a fault and is damaged, other current-sharing power supplies can continue to provide power to the system, improving the reliability of the system.
EMC optimization design
Rental LED displays need to run with a variety of electronic devices at the same time. In order to avoid electromagnetic interference with each other, the rental LED screen needs to be designed for EMC optimization,such as:
- PCB adopts spike-free wiring design
- low-interference wiring method
- multi-layer copper shielding
- high and low-frequency separation
- multiple processing of sensitive signals and other technologies; multiple filtering
- pure power technology, etc.
- multiple Shielding EMC box structure design
- It will solve electromagnetic interference through the above design.
Silent operation
In some high-end rental LED display occasions, such as museums, concerts, press conferences, etc., there are requirements for the noise of LED displays. Low-noise fans or fanless and low-noise power supplies are required. In to achieve this effect, It will put forward higher requirements on the power supply part.
Low reflectivity
Due to the existence of other light sources such as projections, spotlights, moving headlights, etc., rental LED screens must also consider the issue of lighting.
The LED display should adopt an all-black body packaging design. The combined effect of black PPA material and epoxy resin makes the front of the lamp bead overall black, thereby better improving the contrast of the display.
The colloid surface of the device adopts a matte design. It avoids light reflection caused by the mirror effect of glue, thereby effectively reducing reflection interference and making LED display softer and more vivid.
Intelligent brightness adjustment
During the performance, the display effect will inevitably be affected by stage lighting such as projections, spotlights, and moving head lights. Therefore, it is necessary for high-end rental LED screens to install automatic adaptive photosensitivity adjustment equipment so that the display screen will not be affected by ambient light.
In conclusion
The above are the characteristics of the 7 high-end rental LED displays. As a top used LED screen supplier, IAMLEDWALL provides black light and high-refresh used second hand LED video wall. If you need them, please feel free to contact us.
