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

Back through the 20th century, when televisions were the black and white entertainment boxes to their progression in the years that followed, colored television was then invented. TV technologies from the Cathode Ray Tube (CRT), Light Emitting Diode (LED), and Liquid Crystal Displays (LCD) gave birth to both computer monitors in Corklaptops in Waterford, and all the other screened gadgets in other parts of the world.

Since modern gadgets are like mini televisions that can be placed in backpacks and handbags, more ways to innovate such took place through the course of the years, and here are some of them:

Plasma Displays
In the continuity of display evolution, the full-color television was introduced in 1995 as Plasma Display. This tech consists of tiny cells coated with phosphor in a glass-filled glass tube, then UV lights are generated through the gas as the gas atoms barrage on cells.

Through plasma technology, TV sizes were reduced because of the absence of the CRT tubes.

OLED Displays

Eastman Kodak in 1987 advanced the discovery of electroluminescence that was discovered in 1907 through the Organic Light Emitting Diode or OLED. The OLED is a film of organic compounds and semiconductors that emit light as a response to electric current. OLEDs also work without the backlight, so the display of deep black color levels is possible.

AMOLED Displays

This type of display is an OLED with an active-matrix. It is a step further from the OLED made with increased resolution and an infinite contrast ratio introduced in 2008. Because of this, screens have become thinner and more flexible, and the display is no longer rigid but smooth.

But as it is stated, AMOLEDs are organic; that is why its “loophole” is in its being organic, which means that the TV or gadget lasts for only several years.
