- Researchers have discovered new host equipment for Blue OLED pixels
- The tests have shown a big leap in energy efficiency
- The breakthrough could mean cheaper production
Good news for anyone who wants a cheaper OLED TV: a new scientific breakthrough could open the way for cheaper and more effective OLED screens in our smart televisions, our phones, our tablets and almost everywhere else – although The impact can be the most important on televisions.
Researchers from the University of Cambridge and the University of Manchester would have discovered new “Oxadiazine” host equipment to create high -efficiency blue oled pixels (via Oled-info).
The Blue OLED pixels are the white whale (blue?) The development of the television panel, is much more difficult to produce with the same efficiency emitting than their red and green counterparts, with more risk of instability and a short duration of conservation. Like the summary of scientific journal Said: “Energy economy and deep blue diode (OLED) with long operating stability remains a key challenge to allow a disruptive change in the OLED screen and lighting technology.”
However, it seems that progress is underway. The document shows the molecular design of the new material, with 21% improvement in energy efficiency and excellent “thermal stability” for use in blue OLED pixels.
And although all OLED devices use blue pixels, the reason why it is particularly good for televisions is that even the most recent and larger television technology requires several layers of blue pixels, so this is where the effects The most important can be felt.
OLED’s future
There has been a great push in recent years towards the development of “Phosphorus Oled” panels with greater energy efficiency and higher brightness
This means that a television screen can deploy less layers of blue pixel for the same brightness output as existing screens.
The latest RGB tandem panel in RGB tandem with four stages of LG (used in the LG G5 and the Panasonic Z95B), for example, uses more blue layers than red or green. QD-Oled, as used in the Samsung S95F, is strongly based on blue light from a layer of quantum dots, several layers of blue pixels are also needed. Thus, any method of reducing the complexity or cost of blue pixels will be welcome.
Although the Phosphorus Oled has proven to be difficult to make so far, these types of breakthroughs show that progress is in the course of blue.
A laboratory breakthrough like this will take time to have an impact on the production of mass panels, of course, but it omen has a good omen for the development of the OLED in the years to come, and the hope of more expensive and more accessible OLED TVs that offer excellent image quality longer.
While OLED television prices to have Driven in recent years, they have largely blocked the $ 1,000 mark, and manufacturers and consumers were waiting for something to break. I hope this future is not too far away.
