LED displays also cost 40 to 60 percent less per thousand viewers than most other forms of advertising. In fact, businesses can communicate with thousands of people each day for just a few dollars.
When purchasing an LED display, it is important to understand a few basic principles that will help you select the right product for your application. The following sections present a brief overview of some of these basic principles.
Pitch (Resolution) / LED Diode Density :
Pitch Resolution, is the total number of pixels in a display. More resolution means more LED diodes and more circuits, which usually means better picture quality. LED density of a display is the total number of LED diodes in one square meter. Our high-density of super-bright, high quality LED diodes typically exceeds standards by a long shot.
Viewing Distance / Viewing Angle
Longer distances require less resolution and shorter distances require higher resolutions. With wide viewing angle LED’s, the image is visible in consistent brightness and uniform colors throughout the entire viewing range of the display.
Brightness
The Brightness of an LED display is generally expressed by a numerical value in NITs. A NIT is defined as unit of illuminative brightness described as candela output per square meter (cd/M2). The higher the number of NITs, the brighter the display. In general, 1,500 NITs, provides readable text in outdoor daylight, while grayscale and outdoor video require up to 5,000 NITs for acceptable color depth.
Our high-density of super-bright, high quality LED diodes typically exceed this standard by a long shot. Contrast ratio is another important factor in overall brightness, and refers to the difference between levels of blacks compared to the levels of whites in the display. Things like reflective surfaces, glare from the sun, and dimming all affect contrast ratio. To optimize the contrast ratio and overall brightness,
LED
The LED light emitting diode.
LED panel
Through a certain control, the LED array device composed of the display screen.
Dual-color LED display
The red, green, blue three primary colors in any two-color LED device composed of LED display.
Full-color LED display
The red, green, blue three-color LED device composed of LED display.
Brightness
LED display unit area of luminous intensity. Unit: Candela / m 2 (cd/m2).
Gray level
LED display with a brightness in the dark from the brightest to the brightness difference between the series.
Pixel
The smallest LED display imaging unit.
Module
The number of pixels that the composition, structure independent of the composition of the smallest LED display modules.
Best viewing angle
The direction of the LED display brightness down to the normal direction brightness half, the same plane with the two directions of a normal direction by the angle. The level into perspective and vertical viewing angle.
