What is the difference between LED and OLED?

LED is a light-emitting diode, the material used is based on 3A-5A elemental compound semiconductor, LED according to its luminous wavelength to distinguish, can be roughly divided into visible light diodes and infrared light-emitting diodes. Its luminescence principle is to use the semiconductor electrons and holes combined, the release of energy in the form of photons to emit light. Generally used in information billboards, infrared products, traffic signals, lighting equipment, optical fiber products.

OLED is an organic light-emitting diode, the use of a new organic semiconductor material (that is, a material containing hydrocarbons), it is coated on a conductive glass sheet, through the current, you can release a variety of different wavelengths of light. OLED is currently mainly used in automotive displays, mobile phones, game consoles, handheld portable minicomputers, personal digital assistants (PDAs), car audio and digital cameras. Etc.

The main difference between LED and OLED is:

Liquid crystal panel is through the backlight light, through the refraction of liquid crystal molecules and produce a variety of different colors, liquid crystal molecules themselves can not light, LED refers to the backlight, and OLED itself can light, do not need a backlight.

Leds use metal materials, while OLeds use organic materials

OLED is more advanced, it can emit light independently without light exposure, the contrast is relatively good, and the usually used LED is to have a backlight irradiation to see things.

The screen made by OLED is thinner than LED, shock-resistant, wide viewing Angle, not easy to heat, and high luminous efficiency, and LED is almost not used in TV displays.
