This technology has also been called true QLED display, [63] and Electroluminescent quantum dots (ELQD,QDEL, EL-QLED). [64] [65] The structure of a QD-LED is similar to the basic design of an OLED. The major difference is that the light emitting devices are quantum dots, such as cadmium selenide (CdSe) nanocrystals. A layer of quantum dots is ...
An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, [1] [2] is a type of light-emitting diode (LED) in which the emissive electroluminescent layer is an organic compound film that emits light in response to an electric current.
This list includes LCD, OLED and microLED display manufacturers. LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material.
We break down the differences between the three main types of TV screen tech – and bring you some of the best models from each category.

Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full-motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market ...
Ching Wan Tang (Chinese: 鄧青雲; pinyin: Dèng Qīngyún; born July 23, 1947) is a Hong Kong–American physical chemist.He was inducted into the National Inventors Hall of Fame in 2018 for inventing OLED (together with Steven Van Slyke), and was awarded the 2011 Wolf Prize in Chemistry. [1]
Steven Van Slyke received his BA degree in chemistry from Ithaca College and his MS degree in materials chemistry from Rochester Institute of Technology.He joined Eastman Kodak in 1979 as a Research Scientist and, together with Ching W. Tang, discovered key materials and thin-film device configurations leading to the demonstration of efficient Organic Light Emitting Diode structures.
