Flat screen TVs are the norm these days, but have you ever stopped to wonder when and how they were invented? It turns out that what we consider modern flat-screen televisions has been evolving for over a century.
Television has come a long way since its inception in the early 20th century. Initially, manufacturers used cathode ray tubes (CRTs) to construct television screens. This technology produced bulky sets with rounded glass displays that took up significant space in living rooms. However, CRT TVs were considered state-of-the-art back then despite their bulkiness and low-quality images.
The first significant step towards the invention of the flat-screen TV came in 1964 when Paul Nipkow presented an electronic system using a metal disk with spirals punched into it. This device was nicknamed “Nipkow’s disc,” which worked by scanning successive lines on an image and transmitting them onto a screen thus formed by illuminated spots.
However, Nipkow’s analysis method did not take off as it was too complex and impractical to be mass-produced for consumer products; instead, companies further developed cathode-ray tube-based displays throughout the rest of the 20th century until liquid crystal display (LCD) technology replaced them entirely.
In 1968 George Heilmeier at RCA Labs described LCD technology he had invented about five years earlier- liquid-crystal materials sandwiched between two layers of transparent electrodes became colored segments controlled by tiny electrical signals that were displayed based on light transmission through the panels’ segments aligned with or against polarizers positioned behind them.
So why does this matter? Well, LCDs would serve as cornerstone building blocks for future flat screen prototypes. By switching between polarizing states at lightning-fast speeds under voltage control from thin-film transistors applied directly next door via photolithography techniques found only available recently discovered within semiconductor fab plants!
Innovation marched on after this initial breakthrough. In the mid-1990s, flat-panel CRT technology was introduced, forming the first ever thin television displays. Additionally, plasma display panels arrived on the scene around this same time period.
In 2002, Sharp released its first commercial LCD TV for consumers in Japan – a sleek design featuring a slim bezel which drew attention to its high-quality picture and viewing angles unattainable with previous technologies such as cathode-ray tubes or projection systems. The response to these new inventions was overwhelming; they paved the way for everything we have now when you look at ultra-thin displays mounted on stylish metal frames adorning walls worldwide!
In recent years advances in LED-backlit local dimming technology have increased brightness and color contrastability beyond what was thought possible just fifteen years ago while maintaining energy efficiency near sustainable levels claimed by eco-minded leaders like Apple Inc.’s current CEO Tim Cook.
Currently, flat-screen TVs come in various sizes ranging from small table-top units to very large screens suitable for home theatre setups or conference rooms. They can also be found to support advanced functionality such as internet connectivity, voice commands and even 3D images that pop out at viewers thanks to special glasses worn by those watching.
Thus it’s clear that our modern-day flat-screen TVs are products of years of technological progress which began over six decades ago– and while there are certainly more innovations likely still ahead as manufacturers seek ways to enhance product performance further without increasing costs too much unnecessary… But one thing is sure: today’s televisions would be almost impossible without this continuing wave of progress built upon generation after generation since Paul Nipkow’s ingenious interpretations revolving “Nipkow disc,” brought about entirely new possibilities all those many decades back!
