Samsung Galaxy S4 to use Green PHOLED

Among the rumours about Samsung Galaxy S4 that come out every day, there is one about the display technology – that the new flagship will use a technology called Green PHOLED. It is still a Full HD OLED and the picture quality is unchanged, but the new display will be 25% more energy efficient than what we have seen so far.

Of course, the sources claiming this may well be making a mistake and confusing PHOLED with FOLED, which is a normal OLED display with flexible plastic substrate (such display is used in the YOUM brand by Samsung). PHOLED, on the other hand, means phosphorescent organic light-emitting diodes. Suppose it’s the latter as Samsung is reported to have been experimenting with different diodes and colours for some time.

The phosphorescent diodes have one particular advantage – they are about 4 times as power-efficient as the fluorescent ones traditionally used by Samsung. The technology has a problem, however – the green and the red PHOLEDs are far more durable than the blue ones, which means that the picture will be deteriorating gradually while the blue PHOLEDs are ‘dying’.

So the solution of Samsung is quite simple – the company will use fluorescent blue diodes and phosphorescent green and red diodes. This will keep the picture of Samsung Galaxy S4 perfect longer and will still result in cutting the power spent for supplying the device with a third or fourth. Since the screens consume the mist of our smartphones energy, this means that Samsung Galaxy S4 will last longer.

So we are even more eager for the special press event in New York on May 14 when the Korean company will unveil its new flagship – Samsung Galaxy S4. Stay tuned with us for the freshest news about the device and live coverage of the conference. You can also follow us on Facebook and Twitter.
