- Researchers have discovered a new host material for OLED Blue Pixels
- The tests showed a great leap in energy efficiency
- The advance could mean cheaper production
Good news for anyone who yearns for a cheaper OLED TV: a new scientific advance could pave the way for cheaper and efficient OLED exhibitions on our smart televisions, telephones, tablets and practically everywhere, although the impact could be larger in TVs.
According to reports, researchers from the University of Cambridge and the University of Manchester have discovered a new host material of ‘oxadiazine’ to create high -efficiency blue OLED pixels, of lower cost (through INFO OLED).
OLED BLUES pixels are the white whale (blue?) Of television panel development, which demonstrates much more difficult to produce with the same light emission efficiency than its red and green counterparts, with more risk of instability and A short useful life. As the summary of scientific role He says: “The Organic Organic Diode (OLED) with energy efficiency with long operational stability remains a key challenge to allow a disruptive change on the OLED screen and lighting technology.”
However, it seems that progress is being made. The document shows the molecular design of the new material, with improvements of 21% in energy efficiency and an excellent “thermal stability” for use in blue OLED pixels.
And although all OLED devices use blue pixels, the reason why it is especially good for televisions is that even the last and best television technology requires multiple layers of blue pixels, so that is where you can feel the biggest effects .
OLED’s future
There has been a great impulse in recent years to develop panels ‘fosffor waves’ with greater energy efficiency and greater brightness
This means that a TV screen can implement fewer layers of blue pixels for the same shine outlet as existing screens.
The last OLEDm RGB Tandem ‘Four-Stack’ of LG (used in LG G5 and Panasonic Z95B), for example, uses more blue or green layers. QD-OED, as used in the Samsung S95F, depends largely on the blue light that arrives through a layer of quantum points, so several layers of blue pixels are also required. Therefore, any method to reduce the complexity or cost of blue pixels will be very welcome.
While phosphor OLED has proven to be difficult to manufacture so far, these types of progress show that progress is being made in blue options in general.
A laboratory advance like this will have time to impact the production of mass panels, of course, but it is a good omen for the development of OLED in the coming years, and the hope of cheaper and more accessible OLED televisions that offer excellent quality of image for a longer time.
While OLED television prices have In recent years, they have stagnated largely around the $ 1,000 brand, and manufacturers and consumers have been waiting for something to break the point. With luck, that future is not too far.
