Curving Radius
Some LED panels can have a slight curve for use in studios,
corporate offices or other applications where a flat wall is not
desirable.
Distance from Presenter to LED
wall
Refers to the distance of the subject on the stage and the LED wall
behind them. This is important for the camera setting needed to
have the correct depth of field, minimizing moiré.
Driving Method
Sometimes referred to as Scan Mode, the driving method tells you
how many LEDs are active at one time. LEDs are turning off and
on at a visually imperceptible speed, this is what helps control the
perceived brightness. If a Driving Method is 1/15 scan, that means
that at any given time only 1/15th of the LEDs are active. This
happens so fast however that it will not be detected by the eye.
Gray Scale
A bit of a misnomer, Gray Scale refers to the color depth, or simply
(perhaps too simply), the number of available colors.
• A 12-bit gray scale will have a potential of 4096 colors (2
12
)
• A 14-bit gray scale will have a potential of 2
14
color or 16,384
• A 16-bit gray scale offers a 2
16
color potential or 65,536 colors
HDR – High Dynamic Range
HDR is a series of technologies that improve the range of color
and contrast in a video image. By offering higher brightness, wider
color ranges, more detail and higher headroom, HDR provides more
lifelike depth and image quality.
IC Driver
The IC Driver controls the state of each individual LED in the LED
panel. It controls the on-off state through Pulse Width Modulation
(PWM) or the more advances Scrambles Pulse Width Modulation
(S-PWN). The refresh rate of each LED panel is determined by the IC
Driver.
IP Rating
Ingress Protection rating provides a range for the level of protection
from solid objects or liquid for electrical enclosures or mechanical
casings.
Mask
Masks are an extra layer of protection for LED pixels. They also
significantly improve the overall image quality and create a more
efficient display. Also known as louvers or shaders, masks are black
plastic screens that cover the face of the module.
Module
A module in an LED panel houses the LED’s themselves. Often two
or more modules will be a part of a single LED Panel.
