OLED (Organic Light-Emitting Diode)

An OLED is a type of light-emitting diode in which the emissive electroluminescent layer is made of an organic compound that emits light when an electric current passes through it. This organic semiconductor layer is sandwiched between two electrodes, with at least one electrode typically being transparent.

Applications:
OLED technology is widely used in television screens, computer monitors, smartphones, handheld devices, digital watches, portable systems, and point-of-sale (POS) devices.

Unlike traditional LCDs, OLED displays do not require a backlight. This allows them to produce deep blacks, resulting in superior contrast ratios—especially in low-light environments such as dark rooms. Additionally, OLED panels are thinner and lighter than LCDs, making them ideal for compact and modern electronic designs.
