LED VS OLED!!! Which is Perfect???

OLED vs LED

     a major breakthrough was achieved with the introduction of OLED displays. OLED stands for Organic light emitting diode. An organic compound is used in the emissive layer of the display, situated between the two diodes of the display unit. Nowadays, OLED has not only been launched in TV sets and monitors, but has also been introduced in laptops, smartphones, tablets, etc. OLED displays have become very popular and are now being considered as the most important invention in display research in a decade, surpassing LCD and plasma technology.

The Working of OLED screens

     As mentioned, the term OLED stands for ‘Organic’ Light emitting diode. The organic here actually refers to the organic Carbon compound film which is located just before the screen layer. The organic layer molecules become conductive due to the delocalization of pi electrons. The OLEDs have a simple structure of two layers- the emissive and the conductive layer. A voltage being applied across the two diodes, the electrons start to fill in the LUMO of the carbon organic layer in the middle, causing it to emit its own light. OLED displays are therefore much better than LCD and Plasma as they do not require their own backlight at all.

Working Principle of LED

     A light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

     In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material.

     Since light is generated within the solid semiconductor material, LEDs are described as solid-state devices. The term solid-state lighting, which also encompasses organic LEDs (OLEDs), distinguishes this lighting technology from other sources that use heated filaments (incandescent and tungsten halogen lamps) or gas discharge (fluorescent lamps).

Why are OLED TVs so pricey?

     The application of organic materials to a substrate required to build an OLED TV has thus far proven problematic in larger size panels. Low yields at the factory mean high prices at retail. The problem is so vexing that, as I mentioned, only LG is offering consumer OLED TVs at the moment.

    as per my opinion the OLED is very good for use but it is very costly that is very big deal to over come.

    In the world samsung is one of the leading brand to manufacturing OLED Display  , iPHONE X , Xs , Xmax display use is manufactured by samsung only on this is the big think.

     I'm using LED because OLED very costly......↜↝
