Philips Display Innovations Premiering at IFA 2014
MMD, the leading technology company and brand license partner for Philips Monitors, unveils at IFA 2014 various innovations which are attuned to the way people work and live - such as the quest for health and well-being, a desire to be enthralled and entertained, and a wish for style and elegance in home and work environments. IFA takes place from 5 to 10 September in Berlin.
Shifting blue light toward the healthier end of the spectrum
With people spending more time than ever interacting with digital devices, continuous blue-light exposure through extended screen time poses a potential risk of long-term damage to eyesight. Making its debut appearance at IFA 2014, the brand-new Philips SoftBlue display reduces eye fatigue by eliminating emissions of blue light at harmful wavelengths, helping to mitigate the negative impact on eyes and improve well-being. Unlike software-based approaches, the SoftBlue display works using a new technology which changes the peak of the blue-chip in the LED. It does this without detracting from colour fidelity or brightness, so users can enjoy accustomed image quality without the prolonged detrimental effect of blue-light exposure.
Another innovation with a firm focus on delivering a sharper, fatigue-free viewing experience is the 4K Ultra High Definition display, which packs four times as many pixels per inch of screen as Full HD and delivers four times the clarity for the sharpest, most brilliant picture ever. The IFA 2014 show will feature two new, larger additions to the 4K line-up, with 32-inch and 40-inch 4K UHD displays joining the 28-inch version. The larger displays offer even more screen space and clarity for detail-rich entertainment such as movies and games, as well as data-intensive office applications.
Amazing gaming
Taking the game up a level for serious players, MMD is showcasing the 144 Hz Gaming Monitor 272G5DYEB with NVIDIA G-SYNC technology. By letting the graphics processing unit (GPU) control its refresh, this 27-inch display delivers ultra-smooth image motion that includes a more complete trajectory of moving objects - including the critical images that are skipped on displays with standard refresh rates. At 144 Hz, the screen content updates nearly two and a half times faster than a standard monitor, giving players the split-second response speed to target objects more accurately and take their game to the next level.
From after-hours to business hours
Designed with graphics professionals in mind, the new 27-inch Philips 272P4A display with Adobe RGB technology is also on view. With Quad HD (QHD) resolution of 2560 x 1440, the display offers the clarity of detail that is vital in applications that rely on pixel-precise accuracy. With Adobe RGB on board, the display can render far more colours than a regular monitor. Users also have the certainty of colour consistency on every device in the production workflow - for example, images loaded from digital cameras have exactly the same colors when rendered on the display. This saves time and effort for photographers, graphic designers, video editors and other professionals involved in the workflow.
Performance with impressive looks
Excellent technology and performance do not mean compromising on looks - as the new 27-inch 275C5 display shows. Apart from the iconic Moda 2 design in glossy white, the new display features Bluetooth for a tidy, cable-free tabletop or desktop and also supports Miracast. With two powerful 7W speakers for audio performance, the 275C5 can work as a stand-alone music station for the living room.
Rounding out the show are Smart All-in-One touch displays - stand-alone multimedia systems which bring the exciting Android app world to larger screens - and the new 21:9 Panoramic Ultra Wide Screen, with a resolution of 3440 x 1440 for heavy-duty multitasking and data applications.
Visitors to the Philips stand in Hall 22 will have ample opportunity to try out all these displays and see how they perform.

It's good to see an alternative for ASUS RoG Swift.
Also... with all that blue light movement, I failed to find any reliable scientific source claiming that blue led backlight will hurt your sight. It makes me question the whole idea, especially with the visible sun output being orders of magnitude higher. Staring at clear LEDs is bad for your eyes, but so is staring at any bright source of light. The only blue light related thing I found scientists to kinda agree about is that if you have a surgery replacing your natural eye lens with a synthetic, it should have a blue and uv filters similar to ones in the natural lens or else your eye may experience rapid aging symptoms. And even that wasn't 100% certain.
I'd like to find a credible paper, and until that, I call it woo woo. I'm not a great fan of spreading fear to sell stuff.
It doesn't hurt your eyesight. The wavelength of light which you perceive as blue triggers melatonin production in the eye. Melatonin is a hormone that affects sleep. If you keep looking at a monitor that is excessively blue late at night, you will not feel sleepy as fast as if you were looking at a monitor that has a lower color temperature, tending towards yellow. Also, you get eye fatigue and some people report their eyes getting red when staring too long at a computer monitor.
Apparently, the solution for some is to go for yellow-tinted glasses or use F.Lux. I carried out a little experiment with a friend whereby I calibrated his >8500K color temperature laptop display to 6500K. He no longer seems to suffer from eye fatigue. I made 5000K, 5500K, and 6000K color profiles for my laptop display in addition to the reference 6500K profile. I actually yawned and wanted to fall asleep when I was using the 5000K profile in bed; this never used to happen when the laptop was at 6500K.
I get disturbed whenever I am using monitors that are even slightly above 6500K nowadays, after I have spent so much time using my calibrated displays (desktop @ 6500K, laptop @ 6500K, and Xperia Z2 phone @ 6500K). My laptop seemed to have an annoying blue tinge last time I was studying, and I had lent my colorimeter (i1DP) to someone. Had to use a 6000K profile in the meantime to feel right back at home. Got my sensor back and it turns out the display had drifted to 6750K. Made a new profile and all was fine again.
This also explains why office lighting tends to be bluish; night lights tend to be yellowish and allow one to relax; sunlight at midday is 6500K, which contains enough 'blue' to trigger some good melatonin production and keep you well awake.
No woo woo at all concerning these established facts.

Thanks for the info. I found various articles about how it (wavelengths of around 430nm) damages eyes, causes cancer etc, which were disturbing. Eg today's CodeProject newsletter link: http://gigaom.com/2014/09/01/what-is-the-blue-light-from-our-screens-really-doing-to-our-eyes/
When manufacturers claim blue light reduction, it's mostly about decreasing the peak output at this blue-purple spectrum without shifting overall white point.
I have displays with both CCFL backlight, which is said to include peaks in that spectrum, and GB-LED, which has peaks outside of that range, both calibrated and I don't really think that the old CCFL one is evil. The only fatigue I can report is when I have to use monitor with poor viewing angles and bad color reproduction. I can feel that it takes way more effort to process the image, and the difference is clearly visible after working for longer periods.
Regarding sleep, I had an opportunity to experiment with that a few years ago when I was working from home in EU for a company in US. As I had to stay up late, I got some 6000K lights, as well as 2700K ones. If I had to work overnight, I was using the white ones, then turning them off and using the yellow-orange ones around 1-2 hours before going to bed. It was really effective, as such combination was letting me to work for longer periods without sleepiness, at the same time allowing me to sleep comfortably after work.
Also, I've been using f.lux too, when I was reading for longer periods in the evening, when it had little to do with my work. Combined with adjusting color of light in room, it seemed to help. On the other hand when I was sleeping in periods which didn't vary from day to day, I didn't need any extra helpers and white room light and no f.lux was fine. There was time when I was convinced that this light color really affects my sleepiness until I switched to dark theme in Visual Studio to find out later that it had no effect on how sleepy I am when coding at night. It wasn't a conscious decision and wasn't done on purpose to verify blue light thing. I just gave it a try and it stayed like that, as it seems to causes less eye fatigue, at least in my case. But perhaps there were other conditions that might affect how I felt at that time. I can't exclude them, making it an anecdotal proof. Human body is so complicated and there are so many factors, that proving and disproving health-related claims is extremely difficult.
I'd like to see some reliable research in this area. I've seen papers saying that it works for some mammals, but not for humans too. And by reliable I mean a large population with a test group that can't tell who's tested and how, and a meaningful way to measure the outcome, which is well defined before the experiment starts, not research like linked here: http://en.wikipedia.org/wiki/Melatonin#Light_dependence with a subjective opinion in a group of 20 people. In my eyes, such experiment is a waste of time, as it's unreliable. After learning so much about statistics, data mining, survey sampling, and having several doctors in family, I'm skeptical. I don't say I could prove that it's wrong, but that there's not enough proof how it works, and the experiments were frequently dodgy, even with samples of 6 people.
If f.lux seems to work for some people, that's fine. If someone prefers different lighting for early and late evening, that's fine. I don't ask to throw f.lux, tinted glasses and monitors with reduced blue light away. I even switched to orange lights around 2 hours ago. But the blue light (peak wavelength without shifting white point) reduction fear-inducing campaign is just wrong and evil in my opinion. There's money behind that, as fear sells products that remedy it. If hardware manufacturers are really concerned with health, be it eye damage, or sleep disorders, or whatever - they should invest some money in reliable research, so they could either keep people healthier or find out that the claims were unjustified, so they could spend the rest of R&D money in other areas.
