The History of TV Technology: The Journey to Perfect Black | LG USA

LG OLED TVs are ushering a new category of television. But it's built on a technology that's decades in the making. To understand how we got here â and where we're going, we must first understand the history of TVs.
The first look at TV came at the 1939 New York World's Fair â where black and white TVs were introduced. Then, 14 years later, color images were produced by broadcasting three monochrome images in red, green and blue, simultaneously. But this wasn't enough for those who understood how good television could be, so by the 1980s we were on a mission to reach higher contrast ratios and a superior color gamut, and develop TVs that were also more energy efficient. The result of this quest was the production of the first liquid-crystal display (LED) and Plasma TVs. Both of these types of televisions required dedicated backlighting, making TV sets in the era thicker, heavier and unable to produce perfect black.
Over the next decade, work continued, and in the 1990s came HD TVs â which set a new digital standard with quadruple the resolution of previous televisions. During this time, LCD TVs became thinner and lighter, thanks to LED backlighting, but were still unable to produce a true, perfect black. Flash forward to 2015 â when large-screen organic light-emitting diode displays were unveiled by LG. By using an organic substance that glows when an electrical current is introduced, there's not only no need for backlighting â which results in a remarkably slender display â but because each pixel can be shut off, perfect black and infinite contrast were finally achieved.
