Body. Difference between OLED and LED. Its uses.

Conclusion. Way forward.

 OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLED display offer improved image quality– better contrast, higher brightness, fuller viewing angle, a wider colour range and much faster refresh rates and lower power consumption over an LED display.

About OLED technology:

  1. Organic Light Emitting Diode (OLED) is a newer display technology for mobiles and monitors. It consists of an organic layer sandwiched between two conducting sheets (an Anode and a cathode) with a glass plate the top and bottom.
  2. The carbon-based organic material emits electro-luminescent light when electricity is applied across the two conducting sheets.
  3. The panel is much thinner as it does not require backlight and filters. OLEDs are superior in their exceptional colour reproduction, fast response times, higher brightness and extremely light weight designs.

The Differences between LED and OLED:

OLEDs are made of organic materials.LEDs are made from inorganic compounds.
The pixels of an OLED are self illuminating.The LEDs used to light an LED display.
OLED are expensive, though OLED prices are dropping significantly.LED are currently less expensive than OLED displays.
OLED feature a wider viewing angle than do LED.LED feature a limited viewing angle.
With OLED panels, the colours do not get washed out when viewers watch from extreme angles.In LED panels, the colours sometimes get washed out when viewers watch from extreme angles.
OLED technology offers the ability to develop lighter and thinner display.LED are heavier and thicker display.
OLED are more energy efficient. OLEDs have better Power efficiency.LED consume more energy efficient when compared to their OLED counterparts.
Response Time of OLEDs is faster than that of LED.Response Time of LED is slower than that of OLED.

Uses of an OLED:

  1. Lighting Applications: OLED lighting has the illumination of higher quality, varied panel shapes, and better-diffused light sources. This is used for lightning purposes.
  2. Mobile Phones: OLEDare used in mobile phones.In mobile phone AMOLED technology is used in screens which has better colours and contrast.
  3. Television Sets: Major giants in the industry pushing the use of OLED in television sets. OLEDs have advantages such as they include thin, low cost displays with a low driving voltage, wide viewing angle and high contrast and colour gamut.
  4. Fashion Industry: OLED technology is also used in the fashion industry, the automotive sector, production of cameras, and video games.

OLED has come a long way and is expected to be the mainstream display technology, usurping LEDs and LCDs in the future. However, research is still required to address some of the drawbacks of the technology.
