Corning? EAGLE XG? Glass, the market-leading LCD glass since its release in 2006, provided the perfect surface for high-definition electronics manufacturers. For both the backplane supporting the TFT array and the color filter that enables the full-color display, EAGLE XG Glass gave panel makers the stable, flat, thin, and lightweight substrates they required.
The fact that Corning could produce such a remarkable glass at an affordable price was a big factor in driving down retail prices for FHD TVs. That trend, in turn, helped spur the industry to adopt high-definition broadcast standards in the United States in 2015.
But even with the advancement of 1080p, TV resolution still paled in comparison to smartphones and handheld tablets.
By the mid-2010s, electronics engineers had devised ways to dramatically increase the number of pixels in the same small space, bringing even more brilliance and clarity to large TV screens. Thus were born “ultra-high definition” (UHD) TVs, with resolutions of 3840 by 2160 pixels. In casual reference, the industry rounded up the horizontal pixel count instead of vertical, and the platform became popularly known as 4K.
The additional pixels brought significant improvements in color, sharpness, and lifelike experience. As more consumers jumped on the 4K bandwagon – and retail prices dropped into a more-affordable range – many video streaming services and cable providers like Netflix and Hulu have launched 4K content, too. EAGLE XG Glass has continued to serve the 4K platform admirably.
Electronics lovers, though, have always yearned for more – more brightness, more clarity, more immersion – all made possible by more pixels. So, it was inevitable that industry innovators would rise to the challenge, and Sharp introduced the world’s first 8K television in 2015.
The resolution of 8K equates to 7,680 by 4,320 pixels. It also creates the most brilliant images ever showcased on in-home televisions, virtually immersing the viewer in the picture on the screen.
Since then, 8K technology has turned from a jaw-dropping fantasy to an intriguing and attainable aspiration. In early 2019, 10 manufacturers launched 8K models at the Consumer Electronics Show – twice the number from the previous year.
