Two professors from the University of Michigan announced at the Display Week conference in Los Angeles that organic self-luminous diode (OLED) screens have a theoretical lifespan of 100 years. They pointed out that the OLED screen consists of red, green and blue parts and does not require a liquid crystal layer and backlight layer, and can emit light on its own.
According to reports, the OLED screen has a switching light-emitting properties, that is, when the power is turned on to show the brightness, and after the power is cut off, there is no light output. The brightness of this screen is proportional to the power-on time, the longer the power-on time, the higher the brightness. The two professors said that in terms of durability, the green diode is the most durable, while the blue diode has the lowest durability. However, if the effect of the blue diode is not taken into account, the theoretical lifetime of an OLED panel can be more than 100 years, or about 1 million hours.
The professors said that this data is based on laboratory aging tests they conducted. Although current OLED technology has significantly reduced the use of blue diodes, it cannot be completely eliminated. It is worth noting that OLED technology has been in development for 35 years.
The announcement of this theoretical lifetime is positive for the future development of OLED technology. As more and more devices adopt OLED screens, consumers can be more confident in using this technology because it has a long life and provides a quality display.
