The Pure Truth About Black and other characteristics of your LED screen
Author: Fabio Aversa
In the past we have talked about some basic information on LED technology. So, to summarize, if you missed something, this brief summary:
* = A semiconductor LED that emits light
* Pixel = bright point of the base, which may contain one or more LEDs
* Pitch is the distance between pixels, in millimeters
* White = perfect balance of pure red, green and blue
* The minimum Screen (MDV) = is the closest you can get the pixelated image. The type of screen, and displays the content type, plays a role here.
* = Small LED Display Modules (4 * 4 cm over 1 * 1m) mounted
* Colors available = up to 280 trillion (65000 * 65000 * 65000).
* Sets the gamma correction = exponential necessary to adjust the color the logarithmic vision of the human eye
We will now take greater detail on other features that define the quality of an LED screen. We have mentioned several the importance of having a pure white (the perfect balance of red, green and blue) to get the best image quality. Let us now see the importance of having pure black.
How can I get a black screen on an LED? Well, does it turn off all LEDs. Very easy, huh? Actually, no. The biggest problem for black with LED screen is that you do not get the black LED. In fact, if all the lights are off, you can not rely on its advanced electronic control system.
Tan mechanical LED display. In fact, everything depends on the dark black shape on the surface can be achieved when the screen is off.
you may end up with a large mirror in black turn off the screen. Therefore, the design of the LED walls is so important because it must be dark without being flat and is reflected as a mirror.
Why, precisely, is colored black so important? It defines the levels of screen contrast LED. The level of contrast is the difference between the light emitted by the screen and the light reflected from the surface of the screen. The lower the reflected light, the contrast is high and therefore the depth of color and natural images.
To increase the level, the LED display professionals including manufacturers supply pamphlets anti-reflection of the light division and do not take it, to increase visibility of the screen even in direct sunlight. The contrast level of an LED display is a key element to consider, including during the massive demonstrations on television.
What should be aware of when an event broadcast live on the LED screen? First, the refresh rate LED wall. The refresh rate indicates the number of times the image is updated most of the television screens have a refresh rate of 50Hz, and only a few products in the last generation have a refresh rate of 100Hz.
Professional LED screens have a minimum refresh rate of 240Hz, which is almost triple that of most monitors TV. The refresh rate is crucial because it determines the image quality: if it is too low, the LED flashes the screen shows an image recorded by a professional camera. Some manufacturers offer a higher refresh rate to 2000Hz to meet the needs of the broadcasting industry, especially for important events with movements fast camera and format HD.
Secondly, be aware of the brightness levels. Depending on location, may have different needs shine. Outdoor events, obviously, need a high contrast of brightness of the sunlight. However, if the event is indoors, you should have a lower brightness to avoid solarization. To give a practical example, on average before the brightness is 2000 to 3000 NTI for indoor use and up to 5,000 to 6,000 for outdoor use NITS LED.
