How to choose a rental LED display?
In popular entertainment activities all over the world, LED displays are playing an increasingly important role. How to choose a rental LED display is a skill that our industry practitioners must master. Here are 7 key points you need to pay attention to
1. EMC design optimization
In applications, rental LED display needs run simultaneously with a variety of electronic devices , in order to avoid electromagnetic interference with each other, we need to be leased screen EMC optimized design. For example: PCB-free wiring spikes design, low interference alignment mode, multi-layer copper shielded, high-frequency discrete, multi-sensitive signal processing technology; more optimized circuit design, such as MFT, clean power technologies; multiple EMC shielding box structure design, etc., via above designed to solve electromagnetic interference.
2. The automatic correction
What is “automatic correction”? Correction data is stored on the module, replace the module, receiving card, sending card without any debugging without having to resend the data, it can display once with the power.
Traditional “point by point correction” correction technology, the replacement of modules, receiving cards require professionals to operate to resend the corrected data; number needed for each module, create a folder to store the appropriate correction factor module, stored on disk or U mobile hard disk, with a post-module are not imported coefficient color patches will appear; if the user is lost once the correction coefficient, the correction can not be enabled.
Users need to save individual modules correction coefficient, and good recording module number, making it one correspondence; receiving replacement cards or modules need to re-import the correction factor, such as the replacement has a “move correction” technology leasing screen, user-replaceable module after receiving the card or group without any debugging, for the like; the effect of the entire screen are corrected, no color, color, blurring-screen and so on. Just connect to electrify, the entire screen display normal.
3. Housing status monitoring
High-end rental led display receiving card can detect on the cabinet temperature, humidity, power supplies, fans line the signal line communication state detection and monitoring, so that field staff real-time control box running.
4. Dual card, average current N + 1 dual backup power supply
Due to the large number of cabinet led display a large number of electronic equipment configuration, and the inevitable failure rate of electronic equipment has been plagued LED display user. Thus, when the upper part of the screen led electronic devices when a failure occurs, the display is still able to work is particularly important.
Dual card, dual power backup features for under demanding environmental solutions to ensure the reliability and stability of the LED display.
Double sink backup mode, a receiving box using two cards. Receives two cards work at the same time, another hot spare, automatic seamless switching at any one signal fails, ensure that the display foolproof.
In the current power supply in parallel, can be part of the N + m-fold approach to greater power output. Parallel system, each of the current power supply can be shared equally share power less power, when a single main power failure damage, other current power supply can provide power to the system to continue to work to improve the reliability of the system.
5. Quiet operation
In some high-end lease screen applications occasions, such as museums, concerts, press conferences and other noise on the LED display requests, the need to use low-noise fan or no fan noise and low power, and sometimes in order to achieve this effect, power supply section will put forward higher requirements.
6. Intelligent brightness adjustment
In the show, the stage and screen rental led only one light source, the display will be affected projection, lighting, moving lights and other stage lighting. So it is necessary to install the high-end rental display automatically adapts to the photosensitive conditioning equipment, ambient light will not affect the display screen.
7. Low reflectivity
Because of projection, lighting, moving lights and other light sources, but also consider the light-emitting screen lease issues. LED display package devices with full black body design package, by the combined effect of the black PPA material and epoxy resin, so that the overall partial black front lamp beads, in order to better improve the contrast of the display; the device colloid surface using matte design, avoid the light reflected by the mirror effect produced by glue, thus effectively reducing the reflection interference, screen softer vivid screen display.
