OLED: super-sharp images thanks to organic LEDs
The acronym OLED stands for “Organic Light Emitting Diode” and describes super-sharp images in 4K. They are also referred to as a further development of conventional LEDs. The term is particularly well known in the field of television technology. In this article, you can find out more about how organic LEDs work and their advantages.
What is OLED?
As the name „Organic Light Emitting Diode“ already suggests, OLED is a technology with organic diodes. These organic LEDs ensure a special image quality. They are LEDs made from carbon. The compounds used in the conductive layers of the panel are based on carbon molecules.
How do organic LEDs work?
Research into organic light-emitting diodes has been going on since the 1980s. OLEDs can be used to generate flat light. An OLED consists of one or more transport layers and emission layers. The current flow between the two voltage poles around these layers causes negative charge carriers to meet positive charge carriers. This causes excess energy to be emitted in the form of light particles. The production of OLEDs is very complex.
OLED vs. LED
The invention of LEDs is considered a revolution in lighting technology. Both LEDs and OLEDs boast low power consumption with a long service life. However, there are also differences, particularly with regard to displays:
OLEDs are not dependent on external backlighting due to a carbon-containing film that is placed in the panel in front of the glass pane. OLED panels emit their own light and are therefore particularly narrow. The situation is different with LCD displays, where the panel is illuminated by specially arranged LEDs. LCD displays are dependent on a backlight. In addition, inorganic LEDs are considerably more expensive than OLEDs.
Advantages of OLED technology
As OLEDs emit their own light, this technology ensures better contrasts between the display areas. Above all, OLEDs offer a brighter glow than conventional LEDs. The result is a particularly vivid and realistic image. They also impress with lower response times. The low heat development also speaks in favor of the use of organic LEDs.
Application areas of OLEDs
In addition to televisions, OLEDs are also used in smartphones, tablets and PCs. Compared to other devices, OLED screens emit less blue light and are therefore better for the eyes. In addition, OLED can also serve as large-scale room lighting, meaning that this technology plays a key role in conference room technology.
