PMOLED (Passive Matrix Organic Light-Emitting Diode) is a technology widely used in small display panels, such as smart watches and portable devices. This technology has the characteristics of low power consumption, high contrast ratio and wide viewing angle, gradually replacing traditional display technologies such as LCD (Liquid Crystal Display). However, the lifespan and stability of PMOLED panels have also attracted much attention.

First of all, the life of the panel refers to how long the display panel works and the brightness decreases and is irreversible. For PMOLED technology, its lifetime is related to the organic material and panel structure used. Studies have shown that PMOLED panel materials will undergo physical and chemical changes during stable operation, and will gradually deteriorate due to the influence of the external environment. The panel life of PMOLED products from different manufacturers is also different, generally between 5000-50000 hours.

Secondly, panel stability refers to the stability performance of the display panel under different environmental conditions, such as temperature, humidity, pressure, etc. The lack of stability of the PMOLED panel is mainly manifested in the influence of temperature changes on the display of the panel. Both high temperature and low temperature have adverse effects on PMOLED panels. High temperature will cause the panel to turn yellow, reduce brightness and temporarily black out the screen. Low temperature will cause panel discoloration and image distortion. In addition, the influence of humidity on the PMOLED panel is also relatively large, and higher humidity will cause panel distortion and mottled conditions.

 

In order to improve the panel life and stability of PMOLED, the following measures should be taken:

 

1. Choose high-quality organic materials to make panels to prolong the service life of panels.

2. Improve the stability and vibration resistance of the panel, and reduce the influence of external factors on the display effect.

3. Install transition capacitors to make the drive circuit of the panel more stable, avoid voltage peaks or current peaks, and continue to generate electricity.

4. Add a variety of protection mechanisms, such as over-temperature protection, over-voltage protection, etc., to reduce the damage rate of PMOLED panels.

The above is an introduction to the life and stability of PMOLED panels, hoping to help you understand the use and maintenance of PMOLED panels, so that they can be better used in various portable electronic products.
