TECHNICAL DATA OF A LARGE OUTDOOR VIDEO WALL & DISPLAYS
Our Full Color LED video displays are manufactured in our hi-tech factory in Shenzhen, China, using first choice CE and UL components and the HIGHEST QUALITY LEDs, from carefully selected TOP BINS with the ultimate uniformity, widest viewing angles & brightness available on the market, made by Epistar (TW) and encapsulated by Nationstar or Kinglight (China) according to client’s request.
Our LED screens are capable of reproducing from a PC: Text, graphics, animation and flicker-free video, LIVE video, TV, cable, time & date etc… In fact, anything that shows on a PC monitor will show on an LED screen, as it simply acts like a second monitor. Professionals also use a video processor to get multiple inputs and windows…
We make both DIP (Direct In-Line package) or SMD (Surface Mount Devices) pixel types, that produce high quality, vivid images in trillion colors, with excellent CONTRAST. Boards are shipped in MODULES or CABINETS of different pixel pitch configurations. Modules are then assembled together on site within a steel frame or enclosure (built by the client according to our specifications ) to become a large size display board. Putting together MODULES with following specifications inside a frame constitutes a screen.
We give up to 5 YEARS FULL WARRANTY on our boards and provide 24H/7 Customer Support

NOTE:
• Modules sizes are variable, and can be modified according to desired screen size. Standard models for fixed installations use iron or aluminum cabinets, while RENTAL TYPE use slim or die-casting aluminum (in smaller sizes).
They can be back or front service,according to client’s requirements.
• Minimum viewing distance means the distance from where a screen looks DOT-FREE
• * Image quality depends on screen size and minimum resolution.
• **1/3 of max. power is normally used during operation. An electronic dimmer adjusts brightness automatically.
110- 240V- 50-60Hz.
• We can also supply ENERGY SAVING SCREENS (40% less power usage) using special components (extra cost)
METRIC CONVERSION: 30cm=1’ / 25mm=1” / 1Meter=1.1Yard / 1Kg=2.2Lbs. / 0°C=32F
SUPPORTING STRUCTURE / FRAME: ( NOT INCLUDED ) Steel frame, built locally according to our specifications. Usual dimensions: 100-20cm depth & 10- 20cm width. Air-conditioning unit(s) could be necessary in some climates, because ideal operating temperatures are between -10 to +35 °C.
CONTROLLER (or board’s brain): The board works in conjunction with a special CONTROLLER unit (or “brain”), including a computer (supplied) and installed inside the enclosure or in a nearby control room. It also works with a video processor. Only 1 unit is needed per screen, whatever its size.
COMMUNICATION: Direct, by data cable, from the controller unit to the board, via network using Cat5 or fiber optic cables depending on distance from control room to the board, or via modem & high speed Internet from a remote office (cable or wireless).
BRIGHTNESS ADJUSTMENT: Manually by software or automatically by electronic dimmer with light sensor.
SPARE PARTS: A FULL set of spare parts including LED modules, driver boards, LED lamps, power supplies and an extra control cards set are delivered free of charge with your order.
WARRANTY: UP to 5 YEARS on circuits & LEDs depending on LED components chosen. Any damaged part will be promptly replaced free of charge with 24/7 worldwide technical support by e-mail & phone, and on-site support if necessary

PIXEL CONFIGURATION FOR VIDEO DISPLAYS
We manufacture 2 types of pixels: “DIP” (Outdoor only) and “SMD” (Indoor and Outdoor).
DIP PIXELS
Stands for Direct In-line Package where all 3 colors LEDs (R,G,B) are close to one another and constitute ONE pixel.
The PITCH -or distance between 2 pixels- is measured between 2 LED lamps of the same color.
The advantage of this type of pixels is that it has a higher brightness than SMD (up to 30% more) but a lower vertical viewing angle only (60° instead of 160)
SMD 3 IN 1 PIXELS
Stands for Surface Mount Device, where the 3 LED colors (R,G,B) are inserted into one dot between 1 and 3mm square. Available in outdoor pitch 3, 4, 5, 6, 8, 10 and 16. The advantage of this type of pixels is that it has wider viewing angle than DIP (160°H/V), but not as bright (30% less)
