Brilliant LED Production

(English version) Fine and Ultra-Fine-Pitch LED solutions are continuing to explode in applications and orders. Last month in fact, a single display opportunity for a 1.25-mm pixel pitch LED display in the US pushed over $5 million. Opportunities for displays providing native HD and 4K resolution are emerging at an astonishing rate and in all verticals including entertainment, command control and U.S. Government systems. There is a line in the sand, Ultra-Fine-Pitch LED displays are replacing LCD walls and projection DLP systems. LCD and projection technology currently holds a majority of the digital signage market at over 80 percent. Yet LED display image quality has begun to emerge as a rival to these other technologies in many applications and will soon surpass each with the inherent mature display solution. While the display performance design and implementation of Ultra-Fine-Pitch is now competitive, there is significant work ahead for manufacturers to realize the vast market p...

( English version) LED screens came first in the battle with neon signs. LED screens are winning the fight against static billboards. LED and LCD screens become leaders in the in-window advertising throughout the world. Energy-saving LED lamps are getting cheaper and push the incandescent and luminescent lamps from the shops. The advance of digital advertising continues. For several years our Magazine has been covering the trends in the market of LED and LCD displays. The forecasts of reputable international consulting companies show that LED and LED-related applications will have established the leading position in the world markets by 2020. Several factors of efficiency prove this statement: the LED-based products are getting cheaper from year to year; the coefficient price-quality is improving; the dynamic luminous efficiency is growing while the power consumption is falling (which becomes a key factor in conditions of the ever-growing prices on energy-resources). The researc...

(English version)  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 under...
