Progression of TV Technologies from CRT, LCD, LED, OLED

TV technology has indeed taken a far leap to deliver a lifelike experience to every home. With the availability of black and white televisions in the 20th century, people embraced the idea of having a TV set in every household. The invention of the black and white eventually developed into a colored entertainment box that ultimately led to innovation for computer monitors in Corklaptops in Waterford, and all the other screened gadgets worldwide.

A little throwback on how TV progression happened will be a good start.

CRT Technology

After watching the black and white screen for many years, the German physicist Ferdinand Braun invented the CRT or Cathode Ray Tube in 1897. CRT is a television with three electron beams inside the box casing referred to as RGB or red, green, and blue. From these primary colors come the different colors that are displayed on TV screens.

LCD Displays

LCD or Liquid Crystal Display was invented in the 1960s and further researched by James Fergason in 1972. Through his research, the creation of the first modern LCD watch became possible. This invention became the foundation of the flat-screen TVs that most homes have today. To add, LCDs do not emit light directly, which is the electron CRT beams exact opposite.

Quantum-Dot Displays

In 2013, the Quantum-Dot Technology paraded itself and speedily made its way until today. QLED or Quantum-Dot Light Emitting Diode, also known as Quantum dots, are tiny particles (made of semiconductor nanocrystals) used as light sources that carry high-intensity images when hit with light.

Because of this technology, images displayed on TV screens are MORE vibrant and lifelike—think 3D? Oh, there’s so much that QD displays can do, like the possibility that advancement for flat-panel TV screens can only get better in the years to come.
