A “Light-Emitting Diode”, which is a semiconductor device that emits visible light when an electric current passes through it.
A flat panel display, which uses an array of light-emitting diodes (LEDs) as pixels for a video display.
Any area where the light cannot be controlled.
The pixel (a word invented from “picture element”) is the smallest representative unit of a digital image. Pixels are normally situated in a two-dimensional grid, and the number of pixels in that grid determines its overall resolution.
Resolution refers to the total number of count of pixels in a digital image. The higher the pixel density is, the higher the quality / sharpness of the image is.
The distance from the center of an LED cluster (or pixel) to the center of the next LED cluster (or pixel), measured in millimeters. Pixel pitch typically ranges from .9mm up to 10mm.
Pixel pitch directly correlates your display resolution and optimal viewing distance. The smaller the pixel pitch number, the more pixels used to make up the image on your display, therefore improving the resolution and optimal viewing distance. Having a smaller pixel pitch does help your picture, but at a cost.
The nits is the brightness value of a display.
NationStar Technology is the leading manufacturer for chips, LEDs and LED lighting products. It encapsulates the red, green and blue colors within one pixel on a base of gold wire, which is a better conductor and dissipates heat.
SMD: It stands for Surface Mounted Devices, a special type of high power LED lights. With no wires, these devices provide less fuss and seamless application.
COB: It stands for Chip on Board. It takes the LED away from the surface and actually embeds it into the PCB board.
- Cabinets and Tiles (quantity varies per size)
- Power/signal cables to connect between panels and power/signal source cable (quantity varies per size)
- One magnetic tile removal tool
- One Allen key for adjusting panel position
- Aluminum plate to connect panel corners for installation structure (quantity varies per size)
Control Sender Unit (quantity varies per actual resolution of screen configuration)
Power distribution box (distro)
Video processor (based on quantity of signal inputs to be used)
Installation structure or frame
Flight cases (standard packaging is wooden cases)
Colorlight S4 HD
It is a powerful video signal unit that supports DVI and HDMI signal input.
The quantity of control sender units vary per actual resolution of the screen configuration.
The maximum input resolution is 1920×1200 pixels.
The control sender unit can reproduce the content only within a limit amount of pixels, but it cannot scale the content to match exactly. This limitation can easily be taken care of by using a video processor / switcher with an integrated scaler. There are a variety of video processing scalers that can adapt to different resolutions and match to the screens pixel configuration.
Most likely the AV source (ex. Apple TV) was connected directly into the control sender unit. The source does not output the same resolution as the native LED screen.
It is important to consider the input source(s) that will be used and whether or not will be switching between inputs during live screen operation.
Opus LED panels currently support SDI, HDMI, DVI, DP 1.2, HDMI 2.2 and CVBS input formats.
The computer needs to be at a resolution larger than that of the actual wall. If the LED Screen has a resolution of 1700 x768, any content around 1920 x1080 resolution is fine as the content will input into the actual sender control unit “Colorlight player” at 1700 x768.
Once an LED screen is installed on location it should be calibrated immediately. The coefficients of color, gamma, greyscale and brightness are stored within the receiving card of each section. When a tile is replaced, the coefficients are sent directly to the new tile, so it will mimic the original one. Obviously, with age, LEDs dim over time, so regular calibration sessions are recommended every 12+ months.
14-16 bits, this is the best scale available. The majority of the LED displays are 12bits, and the economic LED displays are 8 bits.
MBI 5153 (PWM) is a leader brand / cutting edge technology from Taiwan. The 5153 chip has a higher refresh rate than the 5124 chip.
Smaller the LED there is no room for a mask instead the LED is protected with a coating. When a mask is on the LED overtime could deform with heat influencing the view of it and needing to be replaced.
Only to dealers that have been processed and approved to be an Opus Brilliance Dealer. We do not sell direct to end users.
Many of the LED screens that are sold direct to end users are not Ultra-Fine Pixel Pitch LED Video Display with the same quality and specifications.
The dealer gets our local support and two years warranty.
Additional training to teach the technicians in the installation process is quoted per request.
