LCD less contrast and color appearing yellowish

Hi, PAL,
Since I brought my HTC Diamond HK WWE version on June, and compare with my several friends of HK_Traditional Chinese Version 1.37.842.....
and discovered that mine having much higher contrast as all of my friend's one less contrast and color appearing yellowish....
I'm sure it is the difference of LCD/hardware, as I've flash several ROMs included the said version...
So, does HTC change the spec or supplier of LCD display???
Do anyone has idea of this phenomena ??

hi all,
My Diamond's LCD is also less contrast and the white background appears yellowish. I found out that this batch shipment has this problem and I have checked more than 10 new sets.
Hopefully HTC is looking into this problem. Really disappointed!!

Same here. I have 2 Diamonds, bought a month apart. The new one (arrived today) has lighter contrast and the white screens have a yellow tint. Very disappointing.

Mine also same bought 1 week ago after compare with few friends, Is that the batch problem or HTC going to cut cost using lower grade LCD for future set. Very disappointing (for those who's bought 1 week ago u might think your LCD is prefect, go and compare with 1st batch quality u will go )

So, does anyone contact HTC to get their explanation??
Personally, I'll complaint such disappointed deviation and give them pressure.
Wish you get htc positive response..

hmm, might be that it is just the 'calibration' of the light sensor. When you disable "automatic adjust backlight" and use the slider to set your backlight, all looks fine I believe

Disabling automatic backlight doesn't help improving contrast/saturation...
Would be awesome if someone could come up with a hack that made it possible to adjust contrast on the Diamond... I've played with Resco Photo Viewer and by increasing contrast on photos all looks extremely good.
It's completely insane that they let us adjust backlight strenght but not contrast!!! A contrast settings slider would help tremendously for us with the low contrast / washed out screens!

we knows that htc provided lcd from 2 factories...one that's more white and another that they said more bilanced in color..but if you compare 1 to 1 seems to be better the first...this is not only for the diamond!!!i had 2 htc touch that had the same problem!!!so..be happy with your diamond..white or yellow that is..
p.s i a have yellow..

i am buyers 16.7.2008 is white my friend buyers 15.10.2008 he i yellow

I know that I'm not the only one reporting this, but I'm the first one to provide pictures and video that prove that the problem is not so small as some might think.
It seems HTC started to use lower quality LCD screens with some (maybe all) of the newer Diamond units. These screens have a yellowish tint, and seem to have lower contrast.
Here is the proof (it's a comparison with my old Kaiser):
(both devices are at maximum backlight, and the Diamond's "auto backlight" option is off)
Pictures:

http://img24.imagevenue.com/img.php?image=10597_Picture_005_122_672lo.jpg
The difference seen in the picture is a bit exaggarated in comparison to what I see in real life (even though I did not touch the picture with any editing software, this is right from the camera), so I've included a video too, which more accurately portray the differences:
http://www.youtube.com/watch?v=7cVGORLm-Qc
(in real life the difference is just a bit more pronounced than in this video)
It is important to notice that without a direct comparison to a unit like the Kaiser (or the first batch of Diamonds), it might be hard to know that your Diamond has this phenomena, because even with this phenomena the screen look decent.
My fear is that both types of LCD screens are going to sell with new Diamond units from now on, making those who bought the yellowish screen unable to ever sell the unit for a decent amount of money (when they feel like upgrading).
We need a formal answer from HTC regarding this issue.

Me too, I was sending my TP to repair after using it for 2 months, due some really dissapointed problem like the LCD screen bottom corner peeling off and sliding keyboard starting to become not align with the body.
So they said they're going to replace the LCD 1st and return to me while waiting for the new stock of sliding keyboard. So I just got back my TP from SIS (HTC Malaysian Distributor) today, and found that the screen became VERY yellowish and terrible in different angle-viewing, besides, the new LCD screen viewing angle is terrible, some more fading off and cloudy, like covered with a greyish+yellowish cloud like that!
I did complain to the girl @ SIS, but she said she can't do anything! "this is the NEW BATCH of original screen from HTC!"
But after 'google' thru the net, I've found a lot of other country Touch Pro/Diamond has this issue. And get replaced a new one for them by HTC. Then why Malaysian can't?! This is unfair!!!!!
LET'S SHOUT THIS OUT LOUD TILL THEY REPLACE IT FOR US!!! Check this out, more others has this dissapointing & terrible quality problem for this expensive device!!!

HTC Diamond Screen Contrast

Okay today i bought my US version Diamond from ebay, yeah i said it ebay, im just a poor man w, BUT! The first diamond i had was a UK version which i bought from Expansys 600 $ .
Now i seen many people have this problem the "yellow contrast tint" on the US Diamond, so i am writing this post to ask should i even bother contacting HTC, about the Yellow Tint? and would they fix it (Swap LCD screen out to a normal one), under warranty or even for money?
Or am i better off changing it myself with a replacement lcd screen from ebay or from any where else i can get my hands on one?
Also the reason this is a problem for me, seeing how some people can deal with it, its that the dullness of the screen actually hurts my eyes, seeing how i wear glasses.
Thank you in advance for any advice you may have for me.

Also my display has contrast yellow tint. (Italian Diamond)
The other, however, seems to have the contrast blue tint...

were you able to fix it? My screen has the same problem

hi
no fix htc wont help either and charges 163 to rep the screen so best bet is to buy a diam100 screen and rep it yourself

I supply HTC Touch Diamonds for my clients and set them up with software that we make here and I can safely say all new Diamonds have the yellow screen. We've tried to source them from several different locations, every one of the new ones has a yellow screen. The ones we get are mostly DIAM100's as well, so the model number doesn't dictate the screen tint. I've still got one of the original diamonds with the proper white screen and I'm glad I do as I can't stand the yellow ones.

CAN SOMEONE PLEASE just MAKE A CONTRAST PROGRAM FOR THIS PHONE!!! ITS SUCH A SHAME!!

I've got a US Diamond with a white screen, thankfully.

As far as I know, the underlying technology in the screen doesn't support it, so it'll be a tad pointless.

from what i was led to beleve from orange sum diamonds are made in china (the good ones) while some are made in taiwan for a portion of the price, these cheaply made ones are the ones with the screen tint issue!! i had to return my diamond a few times b4 i finally got a decent one lol

this is really a deal killer for me. i was about to buy a us version than read that us versions are prone to yellow screens but if this is true, even the euro versions are now all yellow!

I am glad to see this issue has been brought up. I've got 2 Diamonds from both regions as well, and can confirm this 100%. It was actually the first thing I noticed when powering on the American Diamond for the first time.
My only guess is that the American version is using a cheaper LCD, as the blacks looks more like washed out grays. The whites, are this off-white cream color, its just not healthy to look at. The backs of both my Diamonds are 'Made in Taiwan'.
So I'm sticking to the European Diamond as it looks a lot better, and I can easily live without 3G.
On the Left, European Diamond
On the Right, American Diamond
Brightness 100% on both:

I have a Vodafon UK version and days before a friend of mine got a diamond that the white was like you say "white cream"....
so you wrong saying that the european version have a cheap lcd. mine is colorfull and bright.

The same problem on my Diamond from Orange Romania.

Same probleme with my Diamond dressed in white ^^, but its not that bad as show on the photo, its only a little bit yellow.

i`m from romania and i buy a htc diamond from france , paris , and the screen its not yellow .... its white/blue .......

LCD display

I broke my digitizer and LCD display and bought the replacements via ebay. Both were "OEM" or whatever.
I replaced them, and the digitizer seems to have worse multitouch than before. I understand that it sucks, but my 2 points never used to get confused when they crossed axis, (or so I dont remember them getting confused).
But also, my LCD seems to have a pink hue to it. I definitely know mine did not have this before the break. I read over a lot of posts here and elsewhere about the pink hue problem. This doesn't appear to be a browser problem, but an actual hardware issue.
Should I return the LCD and get a replacement and hope that the other one I get will be regular, or are my odds slim to none. My previous one was NOT pink whatsoever. And this new one I noticed it right off the bat.

N1 screen isnt LCD... did you get an LCD or an AMOLED?

Well it's LCD with LED backlight. I believe the company I got it from off Ebay got the OEM product directly from Samsung.
It is the same as the one I had before. The part number on the display is the same as the one on my original cracked one, 60h00287-00p

So the colours are a lot more bland and the black isn't really black? You would most definitely know if you got an LCD, it would look ugly compared to what you had.

Are you SURE its an LCD? as andrew said, the nexus only has an AMOLED screen which is a completely different technology
if it is indeed an amoled, then you may have gotten an ATT nexus amoled which is known to have a purple/pink hue

Well what I'm saying is the p/n written on both displays are the same, both from samsung. Which means, yes, it is a AMOLED display.
I don't think it's a case of an "at&t" display being sent to me. My nexus one was for at&t, and I didn't have such pink issue. But this new display does.

well china sells a lot of fakes and they can match up stuff like that.....
and not all nexus display this kind of saturation. Do you have a picture so we can see the extent of the hue?

it doesn't show up much in pics.
but I think it's beginning to fade. I've been leaving the display up with a red color. and alternating through white and black.
Here's a pic I took. But again, it doesn't show up much in it.

nah its noticeable on the keyboard and borders. use if for a while and see if the screen conditions itself. that is the same hue i believe that some att users were mentioning

It's worse to the eye than in the photo though.
I'll see if it fixes itself.

hopefully it just needs to be broken in

At 100% brightness, the pink tink is barely noticeable.
Actually, anything above 50% brightness and it seems fine. It's when it gets lower than that, it starts to look pink

TFT Screen

Hi all,
Want to to get this phone but HD7 screen is worrying me.....
Is there a lot of difference between tft and ameoled? Will the difference be obvious?
Why on earth would HTC keep the same display as hd2 and not ameoled...

Hi,
the HTC HD7 has a super LCD screen. The HD2 has a standard TFT LCD.
From what I hear super LCDs are comparable to SUPER AMOLED screens.
I think, I saw another thread concerning the same.

If its true then hd7 for me

Yeah from the specs i read, its going to have SLCD, which is just as good as SAMOLED

Can you point me to these specs? I have heard that it has SLCD and the MSM8250 but have not been able to see this confirmed anywhere. I am getting the phone regardless since I passed on the HD2 and kept and Iphone 2.5g on TMO all this time. Either way I am looking forward to WP7.

SLCD are similar to Amoled but is better in terms of battery life. SLCD is good.

AMOLED v STFT
The difference between SAMOLED and SLCD is that high quality SLCD screens are sharper while SAMOLED screens have higher color saturation.
Compare the screen on the G2 and the Vibrant, text looks crisper on the SLCD on the G2, but the colors are more saturated (darker blacks, brighter colors) on the SAMOLED on the Vibrant.
It is because of the sub pixel layout of the SAMOLED display. Overall both work well.

the fact that they have the loudpseakers listed as mono already tells me thats wrong.... There's 2 stereo speakers on the device's top and bottom...
Plus slashgear already mentioned it was a regular TFT, and that the viewing angles match the HD2 to prove this(S-LCD has better viewing angles like IPS)

The reason the G2 looks sharper is also helped by the fact that its got a smaller screen.
If HTC's do have S-LCD screen, does that mean they also have the MSM chipset? People here who have emailed and asked HTC have been replied to saying it has the MSM chipset.... this is really frustrating because theres so many cross-information flying about lol. AHHHH!

The only "msm" chipset is in the g2, 7XXX, the HD7 is using the first gen QSD 8250 commonly misidentified as msm 8250. The second gen snap dragon is QSD 8255, currently ont he desire HD.

S-LCD has a better sunlight legibility, where as OLED, AMOLED and SAMOLED all have bad sunlight legibility.

To be honest, all screens have bad sunlight visibility aside from E-ink displays

I just added this in the screen thread, but just to make sure you guys know!
It is the same rubbish TFT, nowhere near S-LCD or anything like it.

HTC Mozart Left, Samsung Omnia 7/Focus Middle, HTC HD7 right.

That screen is a deal breaker for me. I wish the Omnia were being sold in the US rather than the Focus. I like the form factor better.

I'd love it if it had some sort of metal element like the HD7's chrome bezel!
The brown-grey 'metallic' back is not enough... why don't samsung build 'em like HTC!
I'm going to go and check out the Omnia 7 tomorrow, but i'm worried the plastics won't be up to the HD7.
With the screens switched OFF and sitting on your desk the HD7 looks so so so much more BAWSS!
It's going to be a hard call.

Yeah I really prefer HTC's hardware design and build quality to Samsung. If only they could have put even S-LCD on this phone.
Engadget basically called the screen crap in their review.
http://www.engadget.com/2010/10/20/htc-hd7-review/
Really a shame, I was looking forward to this device. I may ultimately end up going with it still, but the Focus is awfully tempting now.

Is it just me or are engadget's reviews always showing this phone from an angle. When it is viewed directly (which is how any person would look at it normally) the blacks aren't nearly as gray as engadget portrays them.
I will still be getting this phone in a heartbeat and selling my AMOLED equipped Nexus one on launch day.

Engagdet is a joke for reviews of anything.
The'll gobble dicks all day long for "previews" but when it's time for reviews, it's like a complete 180.
(unless its an apple product) Did anyone notice today's halt on all news during the back to mac conference?

[Q] Screen Color Balance Warm?

Just received an Incredible S & have a few questions. Is this the normal color temperature for it's screen. The phone on the right is a Samsung Exhibit II. Both should be at full brightness. Whites on the IncS look like a cream color.

Also odd that I bought the phone from Amazon.com & it seems to be meant for the India according to the software # & that English (India) was the only language option. No wonder there was no sense update. The warranty should still be ok in the US?
I got this phone to use with my legacy T-Mobile data plan for 4g & tethering. Both work fine unlike the Exhibit II but I notice that the wifi hotspot shows a 3g symbol. I seem to be getting 4g speeds tethered(other then ping) to just testing on the phone. So the 3g wifi hotspot is really 4g where there is service?

Can anyone just look at their phone LCD & compare it to another phone or their monitor & tell me if the colors on this phone are suppose to be like this?

I've ask this on another Android forum & have gotten no replies there either. I don't know why, but I hope this isn't how the screen should be normally & everyone is in denial. In any case contacted tech support & they do agree that the color balance is too warm in that picture. So I will be sending it in soon & hope that I get better screen back.

my screen seems normal compared to my mac... guess your piece is faulty ... good luck with the new one

HTC repair had a pretty quick turnaround getting my phone back to me in about a week. Unfortunately they don't tell you what they fixed/replaced. I sent it in for loose USB & warm color screen. The USB is better & even the speaker sounds a little better, but the screen I still think is rather on the warm color temperature side.
Can I have some more confirmation from other Incredible S users if the colors are really this off. It's a shame since the screen looks nice with anything besides white. It's something I could probably live with if this is just how it is with this phone(maybe I'm just too use to cooler screens). Here's another photo comparison to my old Nokia N900. I know the camera has it's own white balance processing but this is how it really looks to my eyes.

Same thing on mine, I think they want to mimic the color temp of AMOLED display that I hate. TBH I really hate AMOLED over saturated colors. Still this thing is a little better than AMOLED still it's nowhere as good as my Dell UltraSharp .

So I'm not alone, but is this the norm or just a panel lottery? I wonder why they can't just supply software controls like on PC's so we can adjust colors to our liking.

I guess this issue is only with the incredible S manufactured lately...one of my friend bought INC S some two weeks back...I compares it with mine (I got it when it got released) n found put that the display had a yellow tint...we reported to the shopkeeper... he told us that this issue is only with latest INC S...
Sent from my HTC Incredible S using xda premium

two of my friends have inc's and their screens have the blueish white tint to the screen as mine is a warmer yellowish tint.
i had to replace the screen on mine a couple of weeks ago and it still has the warmer tint .
have gotten used to it and i only notice if i put it next to my friends phones..

It is a bit warm colour on my IS as well, especially when I compared it to nexus s SLCD version. However, before the comparison I did not feel any uncomfortable looking at the screen.
Without proper tool to analyse the screen and give detailed statistics, It's hard to tell if It's faulty or not.
Different manufacturer/technology makes different screen, such as super amoled tends to be greenish on nexus s and lots of people love it. So I think It's down to personal preference and taste.
However, if you think yours is too warm, don't hesitate to get a replacement.
Sent from my HTC Incredible S using XDA App

THe first batch of Incredible S phones had a ACER manufactured screen, but later the displays came from SHARP which have not the same quality.
I saw this on a Dutch forum:
This guy has 3 Incredible S (don't ask me why.)
Phone A: Bought on 17-03-2011
Phone B: Bought on 20-07-2011
Phone C: Bought on 18-04-2011
It looks like Phone A and C are from the first batch and B with a SHARP screen.
HTC does this also with other phones like the Sensation

So on the chance that HTC would replace my screen I wonder if one could specifically request an Acer? Probably not and they might not even have those screens anymore.
Not sure if ACER would be better anyway since I found this about the Sensation screens "To really sum it up, the Sharp screen is slightly less "vivid" than the Acer. But the Acer has ghosting, tearing and flickering. In short: more issues."
