Introduction to OLED: OLED stands for Organic Light-Emitting Diode, a technology that offers brighter and clearer full-color images with faster response times compared to other flat displays.

Light Emission Mechanism: OLEDs consist of a thin, transparent anode made of Indium Tin Oxide (ITO) and a metal cathode, sandwiching an organic substrate. This substrate includes a hole transmission layer (HTL), emitting layer (EL), and electronic transmission layer (ETL). When voltage is applied, holes and electrons combine in the emitting layer to produce light.

Advantages of OLED: OLEDs offer a wide range of visibility, small size, high image quality, and low power consumption. They provide good visibility from a distance, a wide viewing angle, high color saturation, high contrast, and efficient electricity-to-light conversion.

Applications: OLED technology is used in various devices such as PDAs, audio/visual systems, mobile phones, portable games, personal care appliances, household goods, dynamic information displays, and digital cameras. The range of applications is continually expanding.

Electro-mechanical Properties: OLEDs typically use passive matrix technology, with a logic supply voltage of 2.8 to 3.6 V, a contrast ratio of 1000:1, a viewing angle greater than 160°, a response time of less than 10 µs, and an operating temperature range of 20 to 70°C.
