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

EMC Optimized Design

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

Automatic Correction

What is meant by “automatic calibration”? That is to store the calibration data on the module, no need to do any debugging when replacing the module, receiving card, and sending card, no need to resend the data, you can use it after power on!

Traditional calibration technologies such as “point-to-point calibration” require replacement of modules and receiving cards by professionals to resend calibration data; each module number needs to be created, and a folder is stored to store the calibration coefficient of the corresponding module, stored on a USB flash drive or In the mobile hard disk, the user needs to save the module NOVACLB calibration coefficients separately, and record the module numbers so that one of them corresponds to another; after the receiving card or module is replaced, the calibration coefficients need to be reimported. Block patch; if the user loses the correction coefficient, the correction cannot be enabled.

Rental screen with “auto-correction” technology, users do not need to do any debugging after replacing the module or receiving card, just change; the entire screen is the corrected effect, no color difference, color block, Huaping and other problems, just power on The whole screen is displayed normally.

Cabinet Status Monitoring

The receiving card configured on the high-end rental screen can detect and monitor the cabinet temperature, humidity, power, and fan signal line communication status, allowing field staff to control the cabinet operation status in real time.

Dual Card, Current Sharing N + 1 Power Supply Dual Backup

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

Dual-card, dual-power backup function backup is a solution for ensuring the reliability and stability of LED display screens in high-demand environments.

Dual-receive backup mode, one box uses two receiving cards. The two receiving cards work at the same time and are in hot backup state with each other. When any signal fails, it will automatically switch seamlessly to ensure that the display screen works perfectly.

In parallel use of current sharing power supply, 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 the power share. When a single power supply encounters failure and damage, other current-sharing power supplies can continue to provide power to the system to improve system reliability.

Silent Operation

In the high-end occasions of some rental screen applications, such as museums, concerts, press conferences, etc., there are requirements for the noise of LED display screen. Low-noise fans or fanless and low-noise power supplies are required. Sometimes to achieve this effect, Higher requirements will be placed on the power supply section.

Intelligent Brightness Adjustment

During the performance, there is only one light source for the LED rental screen on the stage, and its display effect will inevitably be affected by stage lights such as projection, spotlights, and moving head lights. Therefore, high-end rental screens need to be equipped with automatic photosensitivity adjustment equipment, which will not affect the display screen due to ambient light.

Low Reflectivity

Due to the existence of other light sources such as projection, spotlights, moving head lights, etc., rental screens must also consider the issue of light emission. Novastar LED Video Controller display packaging device adopts a full black body packaging design. The combination of black PPA material and epoxy resin makes the front of the lamp bead overall black, so as to better improve the contrast of the display. The light reflection caused by the glue mirror effect is avoided, thereby effectively reducing the reflection interference and making the screen body display more soft and vivid.
