Simplified blue OLEDs could lead to higher definition TV screens
A multi-university research team has simplified the structure of high-efficiency blue organic light-emitting diodes, an advance that could lead to longer-lasting and higher definition television screens.
Organic light-emitting diodes (OLEDs) are a class of organic electronics found in smartphones and displays and can be more efficient than competing technologies.
Although OLED television screens have vivid picture quality, they also have drawbacks such as high cost, comparatively short lifespans, and blue light stability.
The screen pixels used in OLED displays are composed of red, green and blue subpixels that light up at different intensities to create different colours.
However, the subpixels that emit blue light are the least stable and can be susceptible to so called screen burn-in, which can discolour the screen.
In a paper published in Nature Materials, a team of researchers from Loughborough, Cambridge, and Northumbria Universities, plus Imperial College London, describe a new design that overcomes these issues and may lead to simpler, less expensive systems with purer and more stable blue light.
The findings may pave the way for TV and smartphone screens that consume less energy.
