All about OLED display

OLED display

OLED TV is a type of TV screen that is based on the way organic light-emitting diodes work (OLED). OLED TV is not the same thing as LED TV.

The OLED screen is based on an organic material that is used in light-emitting diodes as the semiconductor material (LEDs). Displays use organic thin sheets between two conductors. This structure glows brightly when energized. OLED displays can be thinner and lighter than other types of displays because they don’t need backlighting. OLED displays can be seen from up to 160 degrees away, even in bright light, and they only need two to ten volts to work.

Dr. Ching W. Tang was the first person to work on OLED technology at Kodak. FOLED, which stands for “flexible organic light-emitting display,” is one type of OLED. Moreover it promises to bring portable displays that roll up to the consumer market.

LG and Samsung are two companies that sell OLED TVs.

Advantages over LED display

An OLED screen is better than an LCD screen in the following ways:

  • Better contrast, more brightness, a wider viewing angle, a wider range of colours, and much faster refresh rates all add up to a better image.
  • Use less electricity.
  • Simpler design that enables ultra-thin, flexible, foldable and transparent displays
  • Better durability – OLEDs are very durable and can operate in a broader temperature range


OLED is the best display technology. In fact, OLED panels are used to make the most beautiful TVs ever, which have the best picture quality and are the thinnest TVs ever made. And this is just the beginning. In the future, OLED will make it possible to make large TVs that can roll up and are see-through.

LG Display is the only company that makes OLED TV panels right now. Moreover the Korean company that makes displays makes a wide range of OLED TV panels. LG Electronics, Panasonic, Sony, Philips, and other companies buy these panels.


OLEDs have flaws. First, OLEDs cost more to produce than LCDs, however this may change in the future due to their simple construction (some believe that future OLEDs will be printed using simple ink-jet processes).

OLEDs’ limited lifespan (like any display) was a problem a few years ago. Consistent improvement has made this a non-issue today. OLEDs are now durable enough for phones and TVs. Emmissive OLEDs might be problematic under direct sunshine. Some consider contemporary AMOLEDs (such as Samsung’s Super AMOLED and Super AMOLED Plus and Nokia’s CBD displays) superior to LCDs.
