Organic light emitting diodes (devices) or OLEDs are monolithic solid-state devices that typically consist of a series of organic thin films sandwiched between two thin film conductive electrodes. It is a display technology used in many electronic devices, such as smartphones, televisions, and wearables. In an OLED display, each pixel is made up of organic compounds that emit light when an electric current passes through them. Unlike traditional LCD displays, this eliminates the need for a backlight. As a result, OLED displays can achieve deeper blacks and higher contrast ratios, leading to vibrant and more realistic images.
Aromatic hydrocarbons are cyclic, planar compounds that resemble benzene in electronic configuration and chemical behavior. Benzene has the molecular formula C6H6 and is the simplest aromatic hydrocarbon. The carbon atoms in benzene are linked by six equivalent σ bonds and six π bonds.
