Researchers have been successful in developing a new technique that will enhance the existing TV and smartphone displays. This technique will make the displays brighter with enhanced contrast and long-lasting life. In several modern smartphone, tablets, laptop, or TV screens have organic light emitting diodes (OLEDs) to light screens.
Usually, these OLED screens are laced with an anti-glare filter that ensures that it is easy to see images on a sunny day. However, the physics of anti-glare filter traps half of OLED pixels light inside the display. As a result, this naturally halves the energy efficacy of the OLED screens.
The display manufacturers have thus opted to sacrifice the energy efficiency to enhance the overall usability. Scientists at the Imperial College at London have developed next-gen OLED pixels that overcome the aforementioned inadequacies.
Other Potential Applications of New OLED Pixels
The scientists have published their findings in the ACS Nano journal. The study claims that it is possible to generate OLEDs that can bypass the anti-glare filter installed in the screens and give out special polarized light. Further, scientists regulate the chemistry of OLED materials to achieve this. The developers claim that the displays manufactured through such OLEDs will be more energy efficient. It also implies that such displays will have long-lasting battery life coupled with low carbon emission. The scientists expect to make all kinds of screens shine more brightly with better contrast.
While the team at the Imperial College was studying OLEDs for enhancing the displays, they also found that the materials and the technique may have other useful applications as well.
This polarized light generated by the OLED materials have potential applications in transmission, encryption of data, and storage of information and thus can be used for data compilation and computing.
