How To Choose LED Rental Display Products

How to choose high-end products when LED display rentals, high-end LED rental display must have the following 7 technical characteristics: EMC optimization design, automatic calibration, cabinet status monitoring, dual card, current sharing N+1 power supply dual backup, mute Operation, intelligent brightness adjustment, low reflectivity.

[1] EMC optimized design

In the application, the LED rental display needs to run simultaneously with a variety of electronic devices. In order to avoid electromagnetic interference with each other, EMC optimization design of the rental display is required. For example: PCB adopts technology such as spike-free wiring design, low-interference wiring, multilayer copper shielding, high and low frequency separation, and multiple processing of sensitive signals; more optimized circuit design, such as multiple filtering, pure power technology, etc.; multiple Shielding EMC box structure design, etc., through the above design to solve electromagnetic interference.

[2]Automatic calibration

What is "automatic correction"? That is, the calibration data is stored on the module, there is no need to do any debugging to replace the module, the receiving card, and the sending card, and there is no need to resend the data, and it can be used after power-on!

Traditional calibration techniques such as “point-by-point calibration” require professionals to re-send calibration data when replacing modules and receiving cards; each module needs to be numbered and a folder is created to store the calibration coefficients of the corresponding modules, and store them in a 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 of them corresponds; after replacing the receiving card or module, the correction coefficient needs to be re-imported. If the coefficient is not imported after the module is replaced, the color will appear Block patch; once the user loses the correction coefficient, the correction cannot be enabled.

How to choose AL LED rental display products

The rental screen with "automatic correction" technology, the user does not need to do any debugging after changing the module or the receiving card, just change; the whole screen is the corrected effect, no color difference, color block, blurry and other problems, just power on The entire screen is displayed normally.

[3] Cabinet status monitoring

The receiving card configured with the high-end rental screen can detect and monitor the communication status of the cabinet's temperature, humidity, power supply, and fan signal lines, allowing on-site staff to control the running status of the cabinet in real time.

[4] Dual cards, current sharing N+1 power supply and dual backup

Since the LED display is composed of a large number of boxes and a large number of electronic devices, the inevitable failure rate of electronic devices has been plagued by LED display users. Therefore, when some electronic devices on the LED screen fail, it is particularly important that the display screen can still work normally.

The dual card, dual power supply backup function backup is a solution to ensure the reliability and stability of the LED display in a highly demanding environment.

Dual receiving backup mode, one box uses two receiving cards. The two receiving cards work at the same time, in a hot backup state for each other, and automatically and seamlessly switch when any signal fails to ensure that the display screen works without fail.

In the parallel use of current-sharing power supplies, the N+m backup method 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 to work, improving the reliability of the system.

[5] Silent operation

In some high-end occasions for rental screen applications, such as museums, concerts, press conferences, etc., requirements for the noise of LED displays are required. Low-noise fans or fanless and low-noise power supplies are required. Sometimes to achieve this effect, Will put forward higher requirements for the power supply part.

[6] Intelligent brightness adjustment

In the performance, there is only one light source of the LED rental screen on the stage, and its display effect will inevitably be affected by the stage lighting such as projection, spotlight, and moving head light. Therefore, it is necessary to install high-end rental screens that automatically adapt to the light-sensitive adjustment equipment, so that the display screen will not be affected by the ambient light.

[7] Low reflectivity

Due to the existence of other light sources such as projectors, spotlights, and moving head lights, rental screens must also consider the issue of light emission. The LED display package device adopts a black body package design. The combined effect of black PPA material and epoxy resin makes the front of the lamp bead black, thereby better improving the contrast of the display; the surface of the device adopts a matte design. Avoid the light reflection caused by the glue mirror effect, thereby effectively reducing the reflection interference, making the screen display more soft and bright.
