switch to LED monitors

I dont know why dell hasnt done this yet. switch all monitors on desktops and notebooks to LED. did you know that you can run an LED screen at full brightniess and it uses less power than a LCD monitor at the lowest brighting level?!? its cheaper, its energy efficent, and it needs to be done! promote this, if you demote i wanna know why!

yardsale Jan 16	yes thats true
bbr Jan 17	Isn't this just like TFT? Resolution would be a problem.
breakable Jan 17	I would propose to clarify: OLED screens or LED back-lit screens.
yardsale Jan 17	it doesnt matter OLED would be nice but i could deal with LED
mugunth Jan 18	yes.. just ditch LCDs...
yardsale Jan 18	apples new macbook air uses LED screeens and backlit keyboards it amazing! the LED screen is so nice i could look at it for a long time
jordann Jan 19	OLED, please!
yardsale Jan 19	yes keep LCD if thats what you want but they just need to give us an option of witch one we want its really not tehat hard dell
vardanian Jan 19	People here please ask me what is the advantage of LED display vs LCD LCD LED Energy efficiency - + Brightness/Contast - + Longer lifetime + - Everybody needs the choice. Apple is expensive and gives no choice. Though they do the best. Thanx!
urantia Jan 20	some of you sound like you dont understand the diffrence with LCD and LED. All we are talking about here is changing the backlighting of an LCD panel from the bulky CCFL tube Backlight which is bulky, consumes more energy and has a limited lifespan not to mention get dimmer as they get older. Compare that to LED backlighting which is not bulky (allows the panels to become quite thin) consumes less energy, is brighter and allows better color reproduction aswell as lasting longer then CCFL and finally not getting dimmer over time like CCFL. (altho they will lose abit of there brightness over the lifespan of a panel.
vardanian Jan 20	but as far as I know the LED looses brightness faster, may be I am wrong. Anyways LED is not that much expensive vs tubes. i am promoting the idea! thanx
yardsale Jan 21	LEDs keep there brightness for a long time and thell allow for the notebook to lose some thickness bc the pannel can be so thin and save battery life
bbr Jan 24	oLED lifetime is up to 4 years, after which the light quality will be down by 50% oLED = ORGANIC light emitting diodes. so they degarde quite rapidly.
ringerc Jan 24	vardanian: All of the above. An LED backlit LCD display will tend to have a longer life (without the backlight fade of CCFL or other LCD backlight options), be brighter, and use less power. The lighting is also more even, which can be very nice for some sorts of work. The main problem with them is that vendors don't realize that white levels of 400 cd/m^2 or more are JUST TOO BRIGHT for many uses and can be a real eyestrain problem. Such high brightness is also unsuitable for colour correction work and quite a few other uses. This isn't a reason not to use an LED backlight, but vendors MUST provide a brightness control with enough range to bring the brightness down to between 80 and 120 cd/m^2 for reading, graphics design, etc in normal indoor lighting. Dell's 2407FPW (CCFL backlit) is already too bright. I had to turn the RGB "gains" (actually just pixel value adjustments) down to get it to 140 cd/m^2 because the brightness control doesn't offer enough control over the backlight. This means that I've had to sacrifice colour precision to get the brightness low enough. If you're going to support brightness ranges of 80 - 400 cd/m^2 or more, you also need to make sure the brightness control is sensitive enough. It needs around 100 possible values, preferably more like 200, to be suitable for sensitive applications. Since this costs $0, it's well worth including. Existing panels like the 2407FPW would be fine if the bottom end of the range went a little dimmer. On a side note, I have an LED backlit XPS M1330 and I love it. Dell included almost enough brightness range and control (I wish I had one more step down for when I'm using it in total darkness, but otherwise it's perfect) and the backlight is pleasantly even and nice. On full brightness it's pleasantly usable in full sunlight even in Western Australia (which is a seriously hot and bright place). Unfortunately the display is very "cold" and blue, with a white point above 9600K, so it takes a lot of adjustment in the video card LUT to bring it back to sRGB-like 6500K and it's just not practical to bring it to "daylight" like 5000K whites for colour work. Still, you can't have everything, and that and the relatively low resolution are the only thing the M1330 suffers from. NOTE: as pointed out by the original submitter this is NOTHING TO DO WITH OLED DISPLAYS.
tlax112 Jan 24	Another good point is that LED and OLED screens are SO much thinner than the standard dell laptop screens.
yardsale Jan 24	exactly led screens could cut some thinkness of a note book
winoffice Jan 27	I demoted because I do not see any reason to "switch to LED monitors". It would be better for the present to "offer LED monitors", but still keep LCD monitors, because LED monitors continue to be significantly more expensive, and therefore customers should still be able to get a cheaper option.
yardsale Jan 31	ya i understand what your saying but itd be nice for an option
xgas Feb 1	LEDs are nice, but they have shorter life expectancy than LCDs, provide it as an option instead of complete replacement.
ajmukon Feb 12	OLEDs look them up- they are replacing LCD, PLASMA, PROJECTION TV/ Monitors and are natively HD, with a 1,000,000:1 contrast ratio (and i think that # is low)
champ Feb 14	Wow, I can't believe the number of people who don't understand what an "LED monitor" is. Hmm, how to put this clearly... THEY ARE BOTH LCDs! The typical laptop has an LCD monitor with an CCFL (cold cathode fluorescent lamp) backlight. What is being suggested here is to go to an LED backlight for the LCD display, instead of a CCFL backlight due to its higher energy efficiency and resulting longer battery life. Saying "LED vs LCD" is a total misnomer. Try LED backlight vs. CCFL backlight. again, both are LCD panels. On a side note oLEDs are a completely different technology which does not require any backlight, as the pixels themselves give off light. I don't think that's what we are talking about here since people are referring to the Macbook Air, which is an LCD with an LED backlight. I'll support this as long as there's good brightness control. I'd hate to have a fixed brightness. I use laptops in dark rooms often, and I like to have the screen very dark in those instances.
yardsale Feb 14	yes thats what i was wanting
ajmukon Feb 14	okay... that makes MORE sense... now i am regretting voting it down...
expatinasia Feb 20	"An LED backlit LCD display will tend to have a longer life (without the backlight fade of CCFL or other LCD backlight options), be brighter...lighting is also more even, which can be very nice for some sorts of work." As a hardware designer for a couple companies that you might be familiar with, I can tell you that all of the above "facts" are wrong. Where do you get this nonsense?
pjeff Feb 20	@ expatinasia... Everything I've read about this subject says the above facts are correct. If you have information to the contrary please post some links to back up your claims.
iamxyj Feb 21	I'm looking into buying an XPS M1530 myself come Christmas 2008 (or maybe there'll be something else available by then). In any case, I think this laptop DEFINITELY needs some LED backlighting. The truth of the matter is, LED backlit panels are much thinner. The LED backlit M1330 is 0.1" (0.87" vs. 0.97") thinner than the regular CCFL backlit M1330 (that's a quater of a centimeter if you care). Considering how "thin" laptop panels are, 0.1" (0.254cm) would make a visible difference and would make the M1530 look even more stunning than it already does. Mr. Dell, please bring LED backlighting to the XPS M1530 as an option just like you did with the M1330~
iamxyj Feb 22	I've been doing a lot of reading about the M1530 lately and I just found a review on PC MAG website dated at Jan 30, 2008 that states the following: "Unlike the XPS M1330 and the Macbook Pro 15-inch (LED), the M1530 doesn't yet have an option for an LED screen. (LED options will be available early this year)." (link: http://www.pcmag.com/article2/0,2817,2254452,00.asp) Is this true? I mean I wouldn't be surprised if LED backlighting eventually hits the M1530 (I'd be surprised if it doesn't) but is the claim that it will happen early this year true? PS: I forgot to 1-up Champ regarding the LED vs LCD misnomer. People, LED backlighting doesn't replace LCDs, it replaces the CCFL used in the backlight of LCDs to make the whole assembly thinner, more energy efficient, brighter, more colorful, etc. For example: CCFL + LCD Panel = what we have now, relatively thick LEDs + LCD Panel = what we want as an option, relatively thin. OLEDs is something completely different, it's a new technology with only prototypes available from companies like Sony and Samsung.
yardsale Feb 23	not just on the XPS on the inspirons
yardsale Feb 24	yes dont forget about the little guy!
jdelidc Mar 9	demoted because i don't like seeing the flicker in crt/plasma/led. it drives me nuts after a while. (granted setting it to 85 htz clears it up but still) but would be a nice option
jdelidc Mar 9	not to mention tv studios would not want flicker on camera so they gotta use lcd
chernobyl Mar 19	Couter productive pricing. Although OLED offers a better picture quality compared to current LCD, I would not like to pay a premium for the OLED experience.
chernobyl Mar 20	And when it does its all mine!!!!!
matt_d Apr 21	Sony's OLED TV, the XEL-1, is 11 inches, and has a retail price of about $2500. As the technology matures, the price will come down.
sin Apr 27	iamxyj explained it rather well. I alwo want an m1530 with LED backlighting, as I've seen the difference between LED and CCFL on an m1330.
gelatinousblob Apr 30	LED screens will be the norm within a year as mass production makes production cheaper and more universal. Their advantages seem pretty clear.
jdelidc Apr 30	i'm buying LCD until it's discontiunued. even then i'm going to be looking for used ones. don't care what the norm is. see my mar 9 comments
paperpilot Apr 30	A better display alternative would be the thin CRT, which Cannon has been developing under the moniker SED. Unfortunately the technology is tied up in the patent courts for the time being.
jimmy_p May 1	LCD's don't flicker because of refresh rate, LED or CCFL.
kidell May 9	LEDs reflect a lot of the background details. i feel it very bad like psp. dont u ppl feel that way
scott31337 May 20	LED LCD is an option on some of Dell Portables, and some people are not willing to pay the price for it.
idangold May 29	LED Hi def 1920X1200 for xps 1530... enough said...
metothelimit Jun 11	Does someone know when dell will start to sell in Europe the new models of the xps 1530 with led screen and new graphic card (9600m gt - ddr3 or ddr2?)?
mgri3 Jun 20	dell debería poner como opción en todas las gamas de portatiles xps en todos los países incluyendo españa la pantalla con retroiluminación por led ya que tiene una definición de colores mayor y un consumo menor que te puede dar media hora más de autonomía yo estoy esperando a que integren esta tecnología en los portátiles ya que aporta muchas ventajas tanto a nivel óptico como de rendimiento de las baterías
champ Jun 20	The above run through babelfish: dell would have to put like option in all the portable ranges of xps in all the countries including Spain the screen with backlighting by LED since it has a greater definition of colors and a consumption smaller than can half an hour give more of autonomy I to you I am hoping to that they integrate this technology in the portable ones since contributes many advantages as much to optical level as of yield of the batteries
penguinsa Jun 27	If you remove the CCFL and replace with LED, surely that reduces the items that require a high voltage. CPU's etc can run on 3.3Volts... OK, maybe you still need 5V for hard drives. But I suspect the latest small drives can run on 3.3V as well... Which means Dell could (eventually) use batteries with less cells. Higher current at a lower voltage equals greater efficiency, and better battery life for a given physical battery size. Sounds good to me !
gamer128 Yesterday	Yardsale's Idea is wonderful! I mean think...It would be great for console gaming! And it's a whole lot better than the current LCD's!
