What are the key points to keep in mind when choosing an LED rental screen?
As an important pillar of the industry differentiated from the solid LED display market, LED rental market due to the low threshold of entry, in recent years to achieve rapid development, the product is to continue to push the new, and presents a trend of high-definition development, point pitch breakthrough 2.0mm below. Due to the red-hot rental market, the industry's professional leasing manufacturers and mainstream enterprises have launched the corresponding products for the market, such as LED rental screen. Then consumers in the choice ofLED rental screenWhat points to pay attention to when? Next, the editorial staff of the Vise will address this issue to introduce you to the next.
Points to note when choosing an LED rental screen:
I. EMC Optimized Design
In the application, LED rental screen needs and a variety of electronic equipment running at the same time, in order to avoid electromagnetic interference with each other, the need for LED rental screen EMC optimization design. For example: PCB using spike-free wiring design, low interference routing, multi-layer copper shielding, high and low frequency separation, sensitive signals multiple processing technology; 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 the electromagnetic interference.
Two, dual card, equal flow N +1 power double 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 part of the electronic devices on the LED screen in the event of failure, the display can still work normally is particularly important.
Dual card, dual power backup function backup is a solution to ensure the reliability and stability of the LED display for demanding environments.
Dual-receiver backup mode, a box using two receiver cards. Two receiver cards work at the same time, each other hot backup state, in any one way signal failure automatically seamless switching, to ensure that the display work foolproof.
In the parallel use of equalizing power supply, N+m backup method can be adopted to output larger power. In the parallel system, each equalizing power supply can share less power equally according to the power share, when a single power supply meets with failure and damage, other equalizing power supplies can continue to provide power to the system to work and improve the reliability of the system.
Intelligent brightness adjustment
In the performance, the stage and only LED rental screen a light source, its display effect will inevitably be affected by the projection, spotlights, moving head lights and other stage lighting. So the LED rental screen is necessary to install automatic adaptation photoregulation equipment, will not be affected by the ambient light and display screen.
Fourth, the box state monitoring
LED rental screen configuration of the receiver card can be box temperature, humidity, power, fan signal line line communication status detection and monitoring, so that the site staff real-time control of the box operation status.
V. Automatic calibration
What is "automatic calibration"? It means that the calibration data is stored on the module, so you don't need to do any debugging to replace the module, receiver card or transmitter card, no need to re-send the data, just power on and use it!
Traditional "point by point correction" and other calibration techniques, the replacement of modules, receiver cards need to be operated by professionals to re-send calibration data; the need to give each module number, the establishment of a folder to store the calibration coefficients of the corresponding module, stored in a U disk or removable hard disk, the user needs to be saved separately from the correction coefficients of the module, and record the number of the module, so that the Users need to save the module correction coefficients individually, and record the module number so that they correspond to each other; need to re-import the correction coefficients after replacing the receiver card or module, if the coefficients are not imported after replacing the module, there will be a color patch; if the user loses the correction coefficients, the correction will not be able to be activated.
With "auto-correct" technology LED rental screen, the user to replace the module or receiver card without doing any debugging, change on the good; the whole screen are corrected for the effect, no color difference, color block, screen and other issues, just power on the whole screen display normal.
Sixth, silent operation
In some LED rental screen application of high-end occasions, such as museums, concerts, press conferences, etc. on the LED display noise requirements, the need to use low-noise fan or no fan and low-noise power supply, and sometimes in order to achieve this effect, the power supply part of the higher requirements.
VII. Low reflectivity
Due to the projection, spotlights, moving head lights and other light sources, LED rental screen should also consider the issue of light emitting.LED rental screen encapsulation device using a full black body encapsulation design, by the black PPA material and epoxy resin comprehensive effect, so that the lamp beads on the front side of the overall black, so as to better improve the contrast of the display; device colloidal surface with a matte surface design, to avoid by the adhesive specular effect produced by the The device gel surface adopts matte design, avoiding the light reflection caused by the specular effect of the glue, thus effectively reducing the reflective interference and making the screen display softer and more colorful.
The above on the choice of LED rental screen to pay attention to what points are shared here for you, I hope this article is helpful to you. If there is still anything you do not understand you can leave a message to the editor, we will answer for you as soon as possible.
