What really does Triluminos and X-Reality Engine technology mean? Is Sony’s smartphone display really worth it?
The Xperia Z Ultra with its 6.4 inch Full HD (1080p) TFT display is really the first super smartphone to have left behind competition and stand out in the crowd. Abiding by it’s specifications, it is clear that there is no one that stands a chance when pit against this gigantic power smartphone.
Sony has done some interesting things in the display zone in regards to the Xperia ZU – the technologies that they are boasting about are Triluminos and X-Reality Engine technology. Let’s throw some light on these and try to understand what Sony is really trying to do here.
If you don’t want to go through all the stuff I am going to write (which honestly is more detailed than the video), just watch the video below:
Let’s at first establish the fact that the Xperia ZU has a 6.4 inch Full HD display resulting into a PPI of 342. While this is quite high, it is still quite low when compared to HTC One which leads the PPI department with an absolute number of 469 (simply because it fits all those pixels in a 4.7 inch screen).
Now, let’s talk about the technology behind the Xperia ZU display.
Triluminos technology resonates with the fact that it has more colors to offer to your eye than the usual conventional LCD displays which offer only a reduced range of colors. This technology uses ‘Quantum Dots’ that emit a specific wavelength and these different wavelengths (by different quantum dots) are perceived as different colors by the human eye. The wavelength depends on the size of this quantum dot which can indeed be controlled precisely.
Often LCDs use a white backlight that passes through RGB (red, green, blue) filters to form colors that we perceive. However, it is very hard to form accurate colors that we actually want to see (or rather should see) which is why conventional LCDs result into washed out colors. With Triluminos, the white backlight is replaced by a blue LED which causes a film of quantum dots to produce pure green and pure red colors. The different wavelengths emitted are then culminated to form the color on the screen that we perceive. How awesome?
I can only think of Samsung’s Super AMOLED display that can offer such high contrast and vivid color reproduction. Hopefully, Sony’s attempt would give Samsung’s sAMOLED some competition and a reason to come up with better display techniques.
The other technology that Sony is talking about is X-Reality for Mobile displays. This is actually a software process which involves calibration, manipulation, a lot of calculation and image adjustments (image processing in short) to make pictures look sharper with reduced noise and with more vivid eye-popping colors. This technology has been borrowed from Sony’s high end TVs.
So while I really appreciate Sony’s attempt to introduce breakthroughs in the display technology for Mobiles, it is only after some real-life spontaneous use that I can comment on with a clear opinion. Right now, all this is text book and obvious expectation. So let’s wait for the review unit to come in and I’ll get back with more info.
