LED or OLED? Often, there is here a likelihood. But even if the two light-emitting diodes are similar in their functioning, there are some differences. And we want to look at here once more that to find out who now really is in terms of environmental performance, energy savings and co..
Structure And Working Principle Of LED And OLED
Both LED and OLED lamp bulb, whose effectiveness is on the load evaluator equal effort of differently charged particles are fundamental. Initially disparate carriers (positive/negative) strive to make on both sides charge equal and mingle through a semiconductor. The only difference in this respect is that LED consist of inorganic and OLED organic semiconductors.
Most important components of the OLED are anode, cathode, substrate (a glass), as well as the light-emitting and the transport layer (of polymer). The current flows through the organic layers from the cathode to the anode, the electrons of the polymer to the emitting layer move.This results in the polymer layer to holes, which then “jump into the emitting layer”, where they are filled by electrons. The electrons in the holes, releasing extra energy as light – and thus become the organic light source. The graphic shows the Schematic of an OLED (right) and LED (left). We have already described the function of a LED in a different blog post.
LED And OLED-What Light Source For What Purpose?
According to Toughestflashlights, another important difference is that OLED Panel spotlights, LED point light sources are. This means that the light of OLED is soft and diffuse, while LED bulbs are suitable as point lighting for room lighting and accent lighting. Also, LEDs have a significantly better luminance, lifetime and efficiency than OLED.
