1- What is the LED?
one of the most frequently asked questions about LED screen, LED stands for light-emitting diode and is a semiconductor device that emits light when an electrical current passes through it.
There are two basic types of LEDs typically referenced: discrete LEDs and surface-mounted (SMD) LEDs, A discrete LED, also known as through-hole or dual in-line package (DIP), is a single conducting component mounted through a hold-punched printed circuit board (PCB) and soldered in place.
An SMD LED is soldered to the PCB via six pins and is typically packaged with at least two other LEDs as a pixel.
2- What is the brightness, viewing angle, and wavelength of the LED?
Luminous intensity is equal to the amount of luminous flux emitted at a very small solid angle in the given angular orientation of the light source. The unit of measurement for luminous intensity is the candela and the symbol is IV.
Viewing angle is the total cone angle in degrees that includes the central high-intensity portion of the LED beam from the apex of the axis to the off-axis point where the LED intensity is 50% of the axis intensity.
This off-axis point is known as half theta (θ 1/2 and twice θ 1/2 is the full viewing angle of the LED, yet light is visible beyond the θ ½ point.
Wavelength is the distance between two points of opposite phase and is equal to the speed of a wave divided by frequency and determines the color that human eyes can recognize.
3- What is the cooling system for display screen? Does the display screen need air conditioning?
one of the most frequently asked questions about LED screen.
Each cabinet has fans for ventilation and we suggest the customer to equip several industrial fans inside the installation structure for ventilation instead of an air conditioner.
What are synchronous and asynchronous system?
Synchronous control:
Synchronous control system device – The most frequently asked questions about LED screen
Synchronous control is a kind of traditional display control technology through computer and other equipment to control the content and effect of LED display. This method usually requires professional control software and hardware to achieve, and the control system needs high performance and high stability.
The main feature of synchronous control is good real-time performance. It can control the content and effect of the display screen in real time through computers and other devices to achieve a high degree of customization and flexibility.
In addition, synchronization control can also realize multi-screen linking through network connection so as to achieve large-scale and complex display effect.
Asynchronous control:
Asynchronous control system device – The most frequently asked questions about LED screen
Asynchronous control is a display control technology that relies on the control card through the control card memory data to achieve the content and effect of the LED display. Control cards often have high storage capacity and processing capacity, and can store a large number of display content and effects, and through calling different control templates to achieve a set Variety of different display effects.
The main advantage of asynchronous control is simple, easy to use, does not need professional control software and hardware, only through the control card memory data to achieve the display effect.
In addition, asynchronous control allows greater flexibility and versatility through wireless communications and other means to enable real-time updates of the displayed content.
Can we do maintenance from the front if the rear installation space is very limited?
Yes, some special displays support front access, and you can remove the units and other accessories from the front side.
Can large full color LED display and sound be provided?
Yes we can supply any large LED display and audio. The LED display will be supplied with function card, subwoofer, speakers (1 pair), video/audio switch, audio tuning equipment and DVD if needed of course these are optional equipment with extra charge.
Do we need to follow some sequence in installation and keep each cabinet in its correct position?
All cabinets are modular and each cabinet can be in any position so there is no need to follow any sequence in installation since the sequence can be set up through the software after installation.
How do you connect wires and cables?
Each cabinet have one pair of power cable (output/input) and one pair of data cable (output/input) and we develop the wiring diagram for each order and customers just need to follow the diagram.
Which method of connecting wires is better, the method of connecting hidden wires or the method of connecting exposed wires?
The hidden wiring method is more stable due to less conductors in the wires and the exposed wiring method is more convenient for operation and easier and faster to replace any wire or cables, For permanent installation, we recommend using the hidden wiring method, and for rental displays we recommend using the exposed wiring method.

4- What is pixel pitch?
one of the most frequently asked questions about LED screen, one of the most Important OF What you should know about LED screens.
Pixel pitch is the distance between the center of a pixel and the center of an adjacent pixel, Typically, pixel pitch is measured in millimeters.
For example, if an LED display has a pixel pitch of 8.0 mm that means the center of each pixel, regardless of how many total pixels there are in the display, is eight millimeters from the center of an adjacent pixel.
Pixel pitch determines the density of pixels in an LED screen, The lower the pixel pitch number, the closer the pixels are together, and thus the higher the pixel density.
Pixel pitch is a very important factor when choosing the right LED display and may be affected by optimal viewing distance, proximity to other LED displays, and other environmental aspects.
