How does LED screen produce different colour at every pixe

 AVR Expos and Orlando Audio Visual Rentals have been assisting with events across the United States since 1988. We specialize in the production of events such as corporate meetings, expos, fundraisers and many other types of events. With so many events that we have assisted with over the years, it’s helpful to know which venues have certain guidelines and procedures that must be followed in order to properly setup and produce an event. That’s why we are here to show you how does LED screen produce different colours at every pixel?

What is an LED?

LEDs are semiconductors that emit light when an electric current is passed through them. LEDs are made up of a number of components including a cathode, an anode and a P-N junction. The voltage applied to the diode determines the brightness and color of the LED. The P-N junction has two layers, one that conducts positive charge and one that conducts negative charge. When charges cross the P-N junction they recombine, releasing energy in the form of light. The type of LED used will determine the wavelength (color) of the emitted light. LEDs have three different ranges for wavelengths: infrared (700 nm), visible (400 nm) and ultraviolet (100 nm). A blue LED for example produces high intensity waves on 400nm range with low power consumption as compared to other colors like red, green or yellow.

How does an LED work?

The LED is a two-lead semiconductor light source. When electricity is applied to the leads, it excites electrons in the semiconductor material and produces light. LED lights create light that is brighter than incandescent lamps and longer lasting than fluorescent lamps. They also consume less power and are more efficient. As an example, our Led wall can provide up to 100% brightness on one of its side while being 50% on the other side with only 20Watts. For this reason, they have become popular for use as a lighting source in commercial buildings and homes. In addition to their energy efficiency, LEDs offer some additional advantages over traditional light sources: they emit very little heat so they don’t require cooling systems; they use less energy than conventional bulbs; they last much longer — up to 100 000 hours or 25 years of continuous operation before fading out! San Francisco Audio Visual Rentals specializes in event technologies such as projection, lighting, scenic, and staging. With the thousands of events across the United States we have assisted with, our knowledge of hotel guidelines and procedures allows us to ensure all needs are met on time!

What are the benefits of using an LED?

LEDs are great for many reasons. They are very energy efficient, which means that they use less power and generate less heat than other technologies. LEDs can also be made in any color (or color temperature) you want. One of the coolest features about LED technology is that because it only uses one color, it produces a much brighter and more vivid light than other technologies like fluorescent and halogen lights, which use mercury to create a variety of colors. Finally, LEDs have a longer lifespan than other types of light bulbs — they last between 50,000 and 100,000 hours before needing to be replaced. That’s 20+ years! So what are you waiting for?

How does an LED screen produce different colours at every pixel?

LED screens are made up of individual pixels, which can be controlled individually to produce any color. To achieve full color, each pixel needs three subpixels — one red, one blue and one green. When a white image is displayed on the screen, all three subpixels shine in full brightness so you see white light. But when an RGB image is displayed on the screen, each of the three subpixels shines only partially — for example, half of the red subpixel shines while none of the blue and green subpixels do. You see a particular color (in this case pink) because only two colors are shining brightly while the other two are completely dark. This means that by changing how much power these two colors get you can change which color you see on the LED wall! For example, if you want to display a purple color on your LED wall then the first step would be to display either an entirely red or blue image. That way, both of those pixels will show their maximum intensity and no white subpixels will show up on the screen. The second step is similar: use your left over sub-pixel to set it at maximum intensity as well so there’s no green or cyan showing up. Now you have successfully created your very own custom purple!
