Facts about virtual pixel technology

We all know that the video management feature in virtual pixel LED screens provides a 400% increase in the quality of images. Unlike a computer screen, LED screens have much less pixels despite its big size because the distance between the pixels is about 30mm or more. So for example, if a normal computer screen has 1024×768 pixels, an LED display 4×3 meters in size will have only 192×144 pixels. That is certainly a big difference!

There are two ways in which a virtual pixel LED really works. One is the geometrical concept where half of two identical pixels placed close to each other are taken to produce two more pixels similar to the original two. When this process of doubling two pixels into four continues, the image quality goes up by 400%. However, this geometrical concept is quite old and not so popular because of one limitation. The multiplication process works fine as long as the distances between pixels are the same. But if a bigger pitch is needed for a higher viewing distance, the distance between the pixels are not equal anymore. As a result, the image quality is affected because the virtual pixels are now stretched.

The other method is the interpolated technology which works much like the MP3 technology that is utilized in the music industry. It is a format derived from the acoustic perception of the human ear. This audio-specific format represents an audio code consuming much less space as compared to other methods of storing audio. Similarly, interpolated pixels are produced by compressing a big sized image into a smaller resolution that is available on the screen. This compression is based on how the human eye visually perceives the image. Because this technology can control the visual perception, it is known as “virtual”. This splendid technology disregards the distance between pixels because the geometrical distribution is of no importance on the image quality.
