LED Screens in All MacBooks by 2009?

Juan Moro said:
Weird... IIRC, the financial chief said in a conference last year that all computers would get LEDs in 2008...

Thats what I said before in another topic before,but wasn't it Steve himself which actually said that last year at WWDC?
I remember him saying:
All displays will be LED backlight in 2008!!
It would be a bummer for me since I am waiting for the iMac to be updated with it but they just got updated.
Do we have to wait 9 months again for the next update?:mad:
Cheers

In a "white" LED, the light emitted from the electronics is typically a bluish color, and this blue light strikes a phosphorous coating on the inner wall of the LED's surface - when excited, this phosphorous coating emits a range of other wavelengths approximating white light.

Where did you get this information? LED's are typically silicon or other materials that are impregnated with impurities to cause a p-n junction. When current is passed through the semi-conductor it causes photons to be released that are in wavelengths of light indicative of the particular material that is used.

Listed below are some of the various substrate used and the resulting color.

Aluminium gallium arsenide (AlGaAs) — red and infrared
Aluminium gallium phosphide (AlGaP) — green
Gallium nitride (GaN) — green and blue also white (if it has an AlGaN Quantum Barrier)
Silicon carbide (SiC) as substrate — blue
Sapphire (Al2O3) as substrate — blue
Zinc selenide (ZnSe) — blue
Diamond (C) — ultraviolet

There is no inner wall phosphorus coating.
 
so...

the revision probably wont have an lcd?

I think this news is kinda good then im not waiting till 2009 to order it just for the sake of a screen thats bright soon as you turn it on.

I got the ok to sell my old one today so I think I'm just going to order a blackbook? sure the revision might have faster processors. but the current one will more then do me as im surviving now on 1.7ghz really old i dont even know what it is.

talking to myself anyway, I think tonight I might just order it I cant wait anymore!

well thinking about it, I've got a question,

what would you suggest buying between the blackbook or the standard macbook pro?

its like a £250 difference in price. I just wondered what the perks would be?

My Electircal Materials professor (BEEng '04). Sorry, it must have been out-of-date informaiton, or else he was misinformed. It's not exactly my area of concentration.

That's what I thought, so for this refresh I would be fine with a built in iSight and built in remote sensor with a little slimming and maybe some slight exterior changes. Also drop the prices just a bit at least and bump the 23" up to 24" obviously. That is all I am asking for! Seriously what is Apple's problem with this??? Why would they possibly take this long to update them?
Click to expand...

I expect Apple likely have shed-loads of these units in stock that they need to whittle down, so with no compelling reason to update them as it applies to the Macintosh platform at this time, they might as well keep pushing them out and recovering the sunk costs of buying them.

Once they are ready to support Blu-Ray and need HDCP support (and likely HDMI support on the portables and the Mini), then we will likely see a serious "fire sale" on the remaining ACD stock as they prepare to launch the new models.

The screen also have a longer lifespand. if you look at a year old macbook and tghe current one, you will easily see that the older screen's brightness have radicaly faded.

No. What you remember and what was actually said are 2 different things. Jobs generally doesn't promise anything verbally that's not confirmed on the web. From A Greener Apple:
Apple plans to reduce and eventually eliminate the use of mercury by transitioning to LED backlighting for all displays when technically and economically feasible.

They won't be updated until Macworld at the earliest. If you need one, buy it.

Yes, but in this case the phosphorous material is used to alter the color of the light by absorbing the yellow band.
Click to expand...
That appears to be in direct contradiction with the text in the article you're responding to.

It stated that, rather than filtering out some of the yellow band, it was actually absorbing some of the light from the blue band to excite the phosphor, which in turn injects extra yellow-band light.

The article said:
The 'white' of white LEDs comes from the narrow-band blue naturally emitted by GaN LEDs, plus a broad spectrum yellow generated by a phosphor coating on the die which absorbs a proportion of the blue and converts it to yellow.

As I stated above, it is very possible that this information, too, is now out of date.

I hadn't thought about the whole Blu-Ray aspect :( But they have to be at least revised by the end of this year according to the statement i referenced earlier about completely getting rid of the chemicals in all the displays by 2008. They better live up to that because this is beyond ridiculous! :mad:
 
Apple Is __not__ Green

Sorry,

I won't be convinced that apple is green until they make iMacs that can be used as an external monitor.

Today you buy an iMac....3 years from now you buy a new Power Mac...you shouldn't need to buy a new display.

Until Apple stops making throwaway products like iMacs or iPods / iPhones with irreplaceable batteries they're NOT GREEN. By irreplaceable I mean by the end user themselves without voiding warranty, or by the manufacturer without charging an insane amount of $$$.

I've done this rant before, look at my other postings.

Let me just end this one in saying that all of the stuff above is what makes apple look horrible as a customer but what makes them look great as an investor. Keep throwing them away and buying new ones and my stock in AAPL will continue to go up.
 
i wonder why anyone would mark this as being negitive. some of these people that mark as negitive need to think twice before they do, to me this seems like a GOOD thing and not bad or negitive in any way shape or form even IF its going to be sometime in 2009 before it happens.

They are going to update the LCD backlight to LED and i am going to mark this as negitive , DUH. positive all the way, only a retard would mark this as being negitive. just cause they cant have it NOW dont mean its a bad thing. if Apple was to just throw out the hardware to customers then Apple would be no better then most of the PC makers out there.

I tend to agree with you but you should write to Apple/Jobs about this directly instead of complaining on a forum where Apple probably won't hear you. (Before you yahoos chime in and claim Apple reads these boards, even if that's true, they don't read every post in every thread written by every person.)
 
MacWorld Paris

What about LED Cinema Displays?!
Click to expand...

New LED Cinema displays (20" and 24") will be announced along with the new "Mac" mini-tower at MacWorld Paris in September.

The 30" won't be updated until MWSF'09 in January - the 30" panels won't hit the right price point before then.

(ps: waiting to order a 55" LED-backlit LCD this fall...)
 
they really need to step up the macbook's to led backgrounds...but then again, they need to do a bunch to upgrade the mbp to justify the price difference at that point..
 
JeffDM said:
They do have dual head being a selling point for their notebooks though, even dual link with their MacBook Pro.
Click to expand...

That reminds me of the only other thing on my MacBook Pro wishlist other than a docking station - dual DVI outputs (so I can connect two external screens).

Hey, Apple, anyone listening ?
 
I decided to wait for these to come out. I can't keep buying over and over again.

I need to do this once. It will kill me to have a new Macbook with LED screen and aluminum casing come out after buying the current one.

I have no choice but to wait. It's frustrating but I only want to do this once.
 
If you need a MacBook, buy it. If you like to wait for the next great improvement in computers, you'll be waiting until the next coming of Jesus. :p

As for the Macworld in Paris, Apple won't be there. So don't hope for anything new then.
 
I find it funny that "same brightness and color range as previous screens" is an advantage. I.e., the advantage is that it is the same and not worse? Haha... I think, by definition, that is not an advantage -- it just is...
