new iphone screen puts blue-coloured spotlight on japan supplier

The success of the IPhone has changed the fate of dozens of suppliers, from glass makers to robotic manufacturers that cut metal shells.
Now, as Apple
A Japanese oil refinery known for its gas station chain is preparing to launch a new smartphone with an OLED screen.

1980. seek to reduce dependence on oil after the global oil crisis.
Now, buy Google\'s latest Pixel smartphone or Galaxy model from Samsung Electronics.
The blue pixels on the OLED screen are most likely made with Idemitsu\'s material or patent.
The wider adoption of advanced displays, the provision of clearer images and the use of less battery power has made Japanese suppliers the focus, which so far have little stake in iPhone sales.
Canon Tokki
For example, giant vacuum machines capable of making OLED screens have almost a monopoly.
Japan Printing Co. , Ltd.
And Toppan Printing Company
It is the leading manufacturer of fine metal mesh required for printing OLED pixels.
\"Samsung has been using OLED screens for several years, but with Apple, it has become a huge boost,\" said Alberto Moer, a technical analyst at Sandford . \"Bernstein & Co.
\"It makes everyone else want to do the same thing.
People familiar with the matter said: \"Apple plans to launch at least one new iPhone with OLED screens this year, which is the 10 th anniversary of the launch of the product.
Cupertino, California
According to industry estimates, the company\'s use of OLED displays will drive demand for hundreds of millions of units.
IHS Markit predicts they will exceed the liquid.
The Crystal display of the smartphone panel is expected to reach $22 this year. 7 billion (roughly Rs.
1,46, 293 crores)in 2017.
Idemitsu\'s unlikely role in OLED technology stems from its early study of blue diodes, which will not last long, but are critical to providing a variety of colors on the display.
The frequency of blue light is higher than that of red and green. it can gather enough energy to cut off chemical bonds.
Even under LCDs for decades, oled has promised to provide better screens.
OLED displays can be thinner, more energy-efficient, and produce a deeper black color because organic pixels can glow on their own, while LCD displays require backlight panels.
They can also be made of flexible plastic for a wider range of shapes and applications.
The challenge of creating a long time is
The price is low enough and the screen is bright for a long time.
When Idemitsu began its development in 1985, OLED was just a promising science.
Japan\'s second in ten years
The largest refinery strives to produce materials that last for more than a few seconds until a breakthrough in extended life.
This makes pioneer company
It includes the world\'s first commercial OLED display for car stereo in 1999.
\"We were there from the beginning,\" said Yuichiro kaw, chief researcher at the Idemitsu Electronic Materials Development Center . \".
With that comes more progress, but South Korean screen makers have invested heavily to produce displays that compete for prices with LCD monitors.
Samsung has put the future of smartphones on OLED, and the vast majority of small displays are currently produced.
LG Electronics Co. , Ltd.
Formed an alliance with Idemitsu in 2009, focusing on TV panels.
Takamitsu Nagase, general manager of Idemitsu electronics in charge of business strategy, said: \"We have had all the key patents for 10 years
Material Department.
\"But only in the past three or four years has it become a real business.
\"While Idemitsu was an early lead in the development of OLED technology, Dow Chemical, Merck & Co.
Other competitors have joined in and invested a lot of money in research to find a better way to produce organic materials.
General Display Company
Founded in 1994 by a former Princeton professor and traded under ticker OLED, commercialize a way to extract more light from organic molecules.
This process includes the use of rare iridium gold.
Help UDC become one of the leading suppliers in the industry.
Others do not believe that the use of heavy elements provides space for technological improvements.
\"Once you add the iridium star, you will introduce restrictions and lose that wonderful Lego toy --
Like the ability to form shapes, \"said Chihaya Adachi, director of the Center for organic photon and electronic research at Kyushu University.
Adachi and his researchers were able to create carbon compounds that never existed before in a week.
This allows them to quickly produce and test tiny OLED square samples for brightness and longevity before returning to the drawing board.
In 2012, this approach made a breakthrough, promising a much lower cost and power consumption, and a much lower color oled.
Idemitsu says the technology is called thermal activation delayed fluorescence (TADF)
Could threaten its blue diode patent, causing greater damage to the status of the UDC.
The existing Idemitsu and UDC are also not stagnant.
Since 2013, the refinery has been working on its own TADF technology and opened a research center in Switzerland in January.
Last year, UDC paid 87 million euros ($93 million)
The entire OLED patent portfolio of basf se.
\"The science behind the blue TADF will be solved this year,\" said Adachi, who is also
Founder of Kyulux Inc.
It\'s a company that commercializes the technology.
\"The next step is to solve the problem of mass production.
