LED uses 3A-5A elemental compound semiconductor materials as inorganic materials, and OLED uses organic semiconductor materials as carbon-oxygen compound materials;

The light-emitting diodes are operated in direct current mode;

The principle of LED light emission is based on the electrons and holes in semiconductors (electrons are negative and holes are positive), which generate energy in the form of photons to emit light, while OLED uses organic molecules to excite electrons between the two electrodes. And electric holes, in order to achieve the purpose of luminescence.

If you compare LEDs with OLEDs, OLEDs have more advantages than LEDs. Due to technical reasons, OLED screens are lighter and thinner than LEDs, anti-vibration, wide viewing angles, not easy to generate heat, and high luminous efficiency. LEDs are rarely used in TVs. . Therefore, although OLED is superior to LED, there is no trend to replace LED.
