A: Confirm led display is used for indoor or outdoor, display content is text or image or video.
1. Features for outdoor led display: waterproof, anti UV, screen brightness can be as high as 6000 cd/sqm to 10000 cd/sqm or above.
2. Features for indoor led display: non-watertight, high resolution, screen brightness is within 1000 cd/sqm to 3000 cd/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 display screen, and make clear if it is curved.
1. The dimension of the led display should be designed according to the installation site. The view distance for most of the audiences should be consulted when design the display dimension. If the display is used for playing videos, the length and width ratio 16/9 or 4/3 for common video display should be taken into account.
2. If the installation of led display is on a curved surface, manufacturer has to confirm the relative figures with clients then accept the order to customize the curved display.
C: How to select led 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 display should be at least 60000 dots and at least 100000 dots for indoor led display. Clients can select suitable led model according to the display area.
2. The display size should also be decided according to the best view distance.
The best view distance means at the certain vertical distance the audience just 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 category installation methods. The first one is led display to be fixed somewhere. Common cabinets are good for this installation because it's cheap. The second one is banner led display to be mounted on wall with front access cabinet structure or with front maintenance led modules. The third one is led display to be transferred frequently, die casting rental cabinets are good for this installation because the cabinets assembling and disassembling and cable connection is simple.
E: How to evaluate the delivery time for a project including the producing time, testing time, shipping time and time for making steel installation structure?
Producing time for led display depends on the size:
Display size is between 1 to 100 sqm, it takes about 7 days to deliver the goods after confirm the order.
Display size is between 100 to 300 sqm, it takes about 15 days to deliver the goods after confirm the order.
Shipping time: It depends on the importers location, shipping method such as shipping by sea or by air or by express delivery, international logistics situation, whether it is holidays and some other comprehensive factors. For details, please refer to your shipping method.
Testing time: Testing time for led display depends on its display area and installation height, usually it's done with 3-7 working days.
Time for making steel installation structure: If making the structure according to our sketch, it takes about 10 working days.
F: How to evaluate the total cost for a led display project?
Formula for calculating the total cost of the project:
Total cost= (cabinet amount x cabinet price ) + Freight insurance + audio and video accessories + desktop computer + power distributor cabinet + cost for steel installation structure.
G: How to select the control system?
1. Control system functional requirements are as below: real-time program transmission, various signal input, set-time broadcasting, signal random switching, live show, multi-screens centralized control, audio-visual synchronization output and so on.
Signal transmission methods include 3g net work, WiFi, LAN cable, Optical fiber and so on.
2. Two categories for control system:
One is synchronous control system, it can make real-time synchronous broadcasting with computer, another one is asynchronous control system, it has been built in content storage playback function.
Control system brands:
For synchronous system brands: LINSN, Colorlight, Mooncell, Nova, etc.
For asynchronous system brands: ECSR, DBS, Huidu, etc.
We select relevant control system according to your requirements to ensure the best control effect.
H: Are there professional technicians doing the cabinets installation and system debugging?
If clients don't have professional technicians to do display connection and do system debugging, but 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.
