Brilliant LED Production

Outdoor LED Displays Market Size By Application (Perimeter Boards, Billboards, Mobile Panels, Video Walls, Traffic Lights, LED Matrix Boards), By Technology (Surface Mounted, Individually Mounted), By Color Display (Tri-Color, Monochrome, Full Color), Industry Analysis Report, Regional Outlook (U.S., Canada, UK, Germany, China, Mexico, Brazil), Application Potential, Price Trends, Competitive Market Share & Forecast, 2016 – 2024. Growing inclination of established corporate brands to advertise products with LED displays will positively boost outdoor LED displays market size. Rising demand for billboards with wireless connections (for regularly changing content) and high resolution displays for scoreboards, hoardings, stadium screens, etc., will fuel the industry trends. Market players often engage in product innovation to be able to cater to corporate demands. For instance, Panasonic, which is already an official partner of the Rio 2016 Olympics and the Rio 2016...

Dynamic brightness range, color rendering and contrast of a LED screen Brightness and color rendering on a LED screen An essential parameter of LED screens is an ability to display a certain number of colors. All visible colors result from color mixing of basic colors that make up a pixel, typically, Red (R), Green (G) and Blue (B). Apparently, the more colors a screen may render, the higher the image quality, provided that the colors are natural and color transitions are smooth. Initially, the image is formed on a computer and image quality is evaluated on a PC monitor. The image on a LED screen must be as close to the initial image as possible. A current de-facto standard is a 24-bit color coding (TrueColor) where the brightness value of each channel is presented as a 8-bit number. Thus, ideally, a high quality LED screen should render at least 2 24  colors (or more than 16 million). We already analysed how the image is generated on an LED screen with the ...

Today we tend to take LED video screens for granted. Indeed, they became common features in our towns and we mostly pay attention to their outward quality parameters. But since our magazine specializes in this technology, we believe time has come to spell out major technical principles of modern LED video screens, those principles that ultimately ensure what millions of people see on screens every day. Modern LED video screen is a complex system with enormous number of components. The image quality and operational parameters depend on the quality of each of those components as well as on the functionality of screen control system. The following LED video screen characteristics are essential from the point of view of image quality: LED video screen resolution (so called  spatial  resolution), in LED video screens it is closely related to distance between pixels or pitch size; Maximum brightness (measured in Nits); Dynamic brightness range understood as the numbe...
