Through the years that have passed, families have included television watching as part of their daily routines. News that are locally sourced and information overseas are easier to access, and it’s all thanks to technology’s evolution. Display technologies used for televisions are the same as the available computer monitors in Cork and other stores worldwide. TV monitors can
also, act as more giant screens for computer users.
During the 20th century, people initially loved the images that come from black and white television boxes. But as years progressed, colored television came, and more improvement happened along the way.
CRT Technology
The Cathode Ray Tube was discovered in 1897 by German physicist Ferdinand Braun. The CRT primarily functioned using three electron beams: primary colors red, green, and blue guided by magnetic charges that produced different colors displayed on screens.
LED Displays
Today, LED televisions are more present in homes that need controlling of backlights or dimming the screen for safer viewing. Televisions that are mostly sold, as well as computer monitors in Waterford, also have this feature. The Light Emitting Diode stemmed from the discovery of electroluminescence (a natural phenomenon where light does not produce heat) by Henry Joseph Round in 1907, which Nick Holonyack improved in 1961. Holonyack then earned for himself the title: “father of the LED.”
OLED Displays
OLEDs are LEDs with an O—and it stands for organic. This type of display technology utilizes either passive or active matrix and works without the backlight; this then allows images projected on-screen to display deep levels of black that make moving images look elegant. Another good thing about OLEDs is that they are thin, flexible, and smaller than traditional LED screens.
There is so much more to learn about TV progression. Take a look at this infographic by Irwin’s Megastore to know more.
