Philips Readies its Own 27-inch AMVA Display

Quickly following on AOC's footsteps, Philips is preparing the release of a self-branded 27-inch monitor equipped with an AMVA (Advanced Multi-domain Vertical Alignment) panel, the 271P4QPJKEB/00. Part of the Brilliance P-line, this incoming widescreen has a W-LED backlight, a native resolution of 1920 x 1080 pixels, 178/178 degree viewing angles, a 6 ms (GtG) response time, 300 cd/m2 brightness, a 5,000:1 contrast ratio (20,000,000:1 DCR), and D-Sub, DVI, HDMI and DisplayPort connectors.

The 271P4QPJKEB/00 also comes with two built-in 2 W speakers, a 3-port USB 2.0 hub, a 2.0-megapixel camera, a 'people sensor' (that lowers brightness when the user is not in front of the display), and a stand allowing for height, pivot, swivel and tilt adjustment. This monitor is available for pre-order priced as low as €400.

€400? Pricey...

And what the heck is w-led? It also uses blue leds with luminophourous coating like in el cheapo series? Not a calibrated RGB led?

W(white)-LED is standard these days for cheap TN and IPS panels. It's cheap to make but it fails when it comes colour reproduction (blue-ish tint).

Yeah there for the sarcasm from me... blueish tint there for they are actually use blue leds, as the have more power covered with luminophourous substance to filter our the light and get somewhat of white like light... cheap trick... I am still proud of my ol' good CCFL :D, But I wish a upgrade.... but everything I approach that is worth the job costs around 1K$ :D

BTW guys... I did an experiment one day... Android and IOS phones support mirroring with certain apps with windows... I've tried it...
Compare the contrast, color capability of those little screens, your yaw will drop and you will have bad dreams afterwards so beware :D

Well NXP Semiconductors is one of the top 20 most biggest semiconductor manufacturers... (counting the revenue...)

Yea CCFL>W-LED, the only alternative is RGB LED but it's rare and very expensive. I'm glad I got a good deal for my monitor, the new version (ZR2440w) is really bad due to W-LED backlight (and it uses a 6-bit panel with A-FRC instead of an 8-bit).

Phones tend to have oversaturated colours, contrast etc. to look "better" ;)

Their debt to equity ratio has been declining for the last few years, meaning despite bullshit numbers made up to please investors by projecting amazing sales and other made up figures, their whole business model is unsustainable currently.

I am using an LG IPS... don't be afraid it is not a samsung amoled phone that I dislike btw also because of the tint... :D

I feel sad your your deal... :( as you see I still live with a humble and small LP2275W... at least it is 8bit and CCFL... and I like it still. Color wise especially.

BTW adding with that Philips legacy... if you are old enough you know Philips bought Sylvania... and the European tube technology from 70ties... the meaning... it has more patents and military technology that you can dream of... it is same caliber as American Raytheon, that also was an old humble tube manufacturer along with RCA. Now Philips works in many spheres like nuclear and medical... these little cheap monitors? I don't really get the Idea for these china rebrands... I think it just a leisure time activity from it's small division to say you know we are still alive and keep the brand naming alive for a simple customer...

When will these manufacturer's stop peddling their 1920 x 1080 27inch monitor crap. The models look nice but I don't buy a new monitor every year or two. And I don't think I am alone thinking this?

If customers want professional/better image quality/better color reproduction they are going to pass over this and all the other recently released 1080 junk.

This monitor is 200 euro too much, priced at ~ $250CAD/USD, or euro, this would be on my "check it out" list. For the kind of $$$ they are asking i could get something MANY times better...

Yeah to pricey. If it would have at least RGB-LED not crappy blue leds...

CCFL better than white LED?????
If CCFL wouldn't became so yellowish over time and the uneven backlight especially due to the darkening of its sides...

After my good ol' IBM Thinkvision died due to CCFL lamps my next one will have the cheap white LEDs that at least have better color and more durable.

Aso not all white LEDs have blue tint... That depends on the phosphor coating the blue or ultraviolet LED similar to the fluorescent lamps and there are high quality white LEDs used in lightning and higher end TV and monitors.

LED are mere zeners and they also degrade over the time... and very fast... same as with CCFL... That is why we still don't have AMOLED screens at home... they have a very short life span.

So I don't understand your frustration...

LEDs have far better lifespan than CCFLs anyway, and AMOLED is a different technology. CCFLs have a abrupt fail mode similar as regular fluorescent lamps, besides the yellowing thing over time and darkening of its ends which make a annoying uneven backlight, while LEDs often fail by simply dimming out over time unless control circuit or associated components fails.

Because yesterday my monitor died due to CCFL lamps burned out while otherwise was fine and I loved it. Also had two laptops with burned CCFL/inverter. And this happened to lots of people over there.

So I didn't understood how said CCFLs are better than white LEDs.

I can tell you one... it is same in sound, some have musical golden ears some don't, same is about sight and color sense. The natural sense balance.

If you measure the spectral artificial white light you'll notice it has several uneven spikes of each wavelength...

Something like that in the image, but way worse... btw same is is with CCFL but more even character...



So. I am trying to say, if to some LED backlit is acceptable. I truly envy you, that you like LED light etc..., so far I've only accepted few RGB solutions, but none with blue leds... the color seems to way off and it irritates me so much deep inside... it is a very subjective thing, there for I mentioned the example with sound. It is the same I suppose - very personal matter of taste.

About that LED vs CCFL life span. I really don't use things over two years, but if I like them... an example of me and my monitor - I sent my HP monitor to RMA at end of third year of warranty and swapped the whole unit... new lamps inside... where is the problem? :confused:

The next thing... I really hate the PWM dimming method of LED's. My eyes hurt watching it... using on max brightness also hurts my eyes during nights... it is like sitting in front of a CRT :(.

BTW I feel sorry also for your monitor... unexpected money spending before Xmas... not fun indeed...

I think what Derek12 was trying to say is that LED backlight can last longer (it's not prone to tinting/dimming as the CCFL is).

However it also depends on the quality of the CCFL, on my last monitor (cheap TN panel) I had to set brightness to maximum to even get a somewhat acceptable bright screen due to CCFL being so old.
Now I have it at 8% and after time the CCFL will wear out yes but I can just correct it by setting it at 12-13% and since there is so much headroom it can last a long time.

But you are right about PWM flicker, very harsh blue light etc. that is the reason that CCFL is still used in newer semi-pro monitors.

AMOLED would be too expensive to make, next step is OLED for monitors but we will see what kind of downsides that has.

I thought OLED stood for organic LED and had a very short lifespan that faded into a very blue screen.

I think it was the blues that would fail because of moisture, leaving you with a blue-less screen.

They have increased the life of blue up to 4,000 and are testing 10,000 hour lifespans if I recall correctly, but it still remains the weakness to OLED on anything larger than a 7" screen that is going to be used for less than 4 years (PSP, Phones)

My next display is going to be a 1440p ips, a korean one, and I hope to keep that for quite a while.

You are right of course! But I wished to say.. LED's are not eternal too... Dumb example, you've seen those big advertisement screens using multi segment LED matrix? Those high power led tend to make failures very fast just as mere Zener diodes do. Those nasty burned out segments... :D It is like Russian space rocket launch success rate. :nutkick:

You are right about putting at lower power settings extends the life span of any device I suppose. The only thing that personally for me failed with ccfl were only inverters... but that is a easy fix. And I bet I was at fault that it broke, due to mechanical shock btw - alcohol you know :laugh: And if it is cheap china it will be cheap china. We all know that.

OLED yes they fade out and the color balance drives in hell... I make my living as mobile phone technician for certain manufacturers. I've seen the first pioneering technologies and results after many years of using the device... first that were mass produced using early OLED's were Nokia 8800 ARTE and same display unit in 7900 and then N85 and N86, after a year their color black level shifted to something bizarre like, of course only on heavy users! Same is with newer SAMOLED units... color balance is so shifted... The technology is still to RAW and undeveloped. I have a Nokia N9 also(big and fast flashdrive), it has the best contrast ratio in the current market, yes indeed, and those deep blacks also, but but... pentile matrix and low resolution, we have to wait for few years still.

Our future are in sLCD and and super IPS tech from Sony, LG and SHARP. Not any of OLED techs.

LoL moisture? No, it is the way of semiconductor degradation graph depending on the chemistry of each light emitter.
