PMOLED (Passive Matrix Organic Light Emitting Diode) is an organic light emitting diode display technology. Compared with other common display technologies such as LCD, LED and AMOLED, PMOLED has lower power consumption, higher contrast ratio, higher brightness and faster response speed. PMOLED has a wide range of applications and is currently mainly used in the following areas:

1. Consumer electronics: PMOLED has been widely used in consumer electronics products such as smart watches, smart phones, wearable devices, MP3 players and e-books. These products require display effects with high brightness, high contrast and energy saving, and PMOLED just meets these requirements.

2. Car display: PMOLED can also be used in display devices such as car dashboards, entertainment systems and navigation systems, because of its high contrast, high brightness, fast response and strong durability.

3. Medical industry: PMOLED can be used in medical equipment, such as mobile monitors, artificial limbs and dentures, etc. Its energy-saving and high-brightness characteristics enable users to clearly see the display content in low-light or low-light conditions .

4. Industrial control: PMOLED can also be used on industrial controllers and monitors to display important production data and monitor equipment status. Its high contrast and high brightness ensure that users can easily read and understand relevant information in low-light environments.

In terms of market prospects, with the popularization of consumer electronic equipment and people's increasing demand for high-quality displays, the market prospect of PMOLED is very optimistic. It is estimated that by 2025, the market size of PMOLED will reach more than 4 billion US dollars, and the compound annual growth rate (CAGR) will remain above 14%.

In addition, with the development of 5G technology and the acceleration of the intelligent process, the market prospect of PMOLED is even broader. The arrival of 5G networks will greatly increase the functional and performance requirements of various consumer electronic devices. As a high-quality and practical display technology, PMOLED will have a wider application space in the future.
