A: Confirm if the LED screen is used indoors or outdoors; display content is text, image, video based or all.
1. Features for outdoor LED display: waterproof, anti UV, screen brightness can be as high as 6,000 nits/s.qm to 10,000 nits/s.qm or above.
2. Features for indoor LED display: non-waterproof, high resolution, screen brightness is within 1000 nits/s.qm to 3000 nits/sqm or above.
3. Single red, single green and single blue color LED displays can be used for playing texts only; RG dual color LED displays can be used for playing texts and simple LOGO images; RGB/full color LED displays can be used for playing texts, images and videos.
B: Confirm the length and height of the LED screen, and also confirm if it is curved, circular, straight or others.
1. The dimension of the LED display should be designed according to the installation site. The viewing distance for most of the audience should be taken into consideration when designing the display dimension. If the display is used for playing videos, the ratio of length and width should be close to 16/9 or 4/3 as standard video display.
2. If the installation of LED screen is on a curved surface, manufacturer has to confirm the detailed information with clients then accept the order to customize such a display screen.
C: How to select LED pixel pitch model according to the display area and resolution of the screen?
1. Resolution of the screen can be calculated according to the screen size. If LED display is for playing video, the resolution of outdoor screen should be at least 40,000 pixels and at least 80,000 pixels for indoor screen. Customers can select the suitable pixel pitch model according to the display area.
2. The targeted model can also be decided according to the best viewing distance.
The best view distance means at the certain vertical distance, the audience can see the whole screen without color shift and the image content is the clearest.
The best view distance = pixel pitch/(0.3-0.8), for example, pixel pitch is 10 mm, then the best view distance is 10/0.3-10/0.8 m, that's about 12.5 to 33 meters.
D: How to decide the cabinet type according to the installation method?
LED display has three types of installation methods. The first one is LED screen that is to be fixed somewhere permanently. Normal cabinets are good for such an installation because it's cheaper. The second one is banner LED display which is to be mounted on wall with front service cabinet structure or with front maintenance LED modules. The third one is LED display that is to be transferred frequently. Die casting rental cabinets are perfect for this kind of installation because the assembling and disassembling and cable connection of such cabinets are very easy to be done.
E: How to estimate the delivery time for a project including the production, testing, shipping and also making steel structure for installation?
Producing time for LED display depends on the size:
Display size is between 1 to 100sqm, it takes about 7-15 days to deliver the goods after confirming the order.
Display size is between 100 to 300sqm, it takes about 15-22 days to deliver the goods after confirming the order.
Shipping time: It depends on the importer's location, shipping method such as shipping by sea or by air or by Express, international logistics situation or whether it is holidays and some other comprehensive factors. For more details, please refer to our shipping guide.
Testing time: Testing time for LED display depends on its display area. Usually it cna be done with 3-7 working days.
Time for making steel installation structure: If making the structure according to our drawing, it takes around 10 working days.
F: How to estimate the total cost for a LED display project?
Formula for calculating LED cabinet qauntities:
Cabinet amount = ( screen width/cabinet width )x( screen height/cabinet height )
Example: screen width is 8.5m, height is 5.5m, cabinet size is 960x960 MM
Cabinet quantities = ( 8500/960 )x( 5500/960 ) = 9 x 6 = 54 PCS
Formula for calculating the total cost of the project:
Total cost = (cabinet quantities x single cabinet price ) + freight insurance + (audio and video accessories + desktop computer + power distributor cabinet + cost for steel installation structure--if needed for these)
G: How to select the control system?
1. Control system's functional requirements: real-time program transmission, various signal input, signal random switching, live broadcast, timed playing in loops, multi-screens centralized control, audio-visual synchronization output, etc.
Signal transmission methods include 3G network, WiFi, LAN cable, optical fiber, etc.
2. There are two types for control system:
One is synchronous control system, it can make real-time synchronous broadcasting with computer. Another one is asynchronous control system, it is geared with a built in content storage playback function.
Control system brands:
Synchronous system brands: LINSN, NovaStar Colorlight, Mooncell, etc.
Asynchronous system brands: Xixun, Onbon, Huidu, Dbstar, etc.
We adopt the control system according to your requirements to ensure of the best control effects.
H: Are there professional technicians providing the cabinets' display connection and system debugging?
If clients don't have professional technicians to do the display connection and system debugging, we can offer free remote debugging service via internet for clients who purchase on our platform. What clients should do is to arrange an electrician who has certain knowledge of computer to assist our engineer to connect the power cables and signal cables.
We hope this LED display shopping guide helps you! Please feel free to contact us if you still have any questions.
