Samsung Electronics has developed a breakthrough in OLED panels. On the 25th, it announced a joint effort with Korea Ewha Women's University to find ways to extend the life of OLEDs.
According to the report, compared with liquid crystal (LCD) panels, the biggest advantage of OLEDs is that they do not require a backlight module and can display pure black. The OLED has fewer backlight modules and lower power consumption, which makes the device lighter and thinner and more promising. However, a major drawback of OLEDs is that blue OLEDs have a limited lifetime, which is only about 5,000 hours, far lower than liquid crystal or plasma panels, which is a major obstacle to the popularity of OLEDs.
Nowadays, the problem of the short life of the blue OLED has been solved. The Yonhap News Agency reported that Samsung's Samsung Advanced Institute of Technology (SAIT) and Ewha Women's University worked together to find out the cause of blue OLED degradation, and found a way to extend the life of OLEDs.
The study found that it is extremely important to control electron transport and reduce the generation of excitons. It is recommended to use a new material composition framework to develop a longer lifetime blue OLED device. This discovery was published in the online edition of the journal Nature Communications.
Samsung's investment in the development of OLED panels is also reminiscent of whether the company intends to restart the OLED TV panel production line.
In order to meet Apple's big orders, Samsung set up the A5 factory last year to produce smart machine OLED panels. Unexpectedly, the iPhone X was less than expected, and Apple's smart machine OLED orders were half-cut, and the A5 factory prospects were questioned. The Samsung A5 factory may be changed to the production line of OLED TV panels.
