Hello all. This is htcuser.. the original poster of the other thread that got closed. i don't know why I got banned.. specially since I was not one of the Op who was flaming on the thread. Well anyways.... I saw this thread and got encouraged to continue my quest in finding out why this is happening to our phone. So as you all know from my other thread... I have another Touch that is useless so I decided to open it up and see if I can find the problem in why we have such a terrible view angle. Last time I went as far as opening up the phone and exposing the screen. I did not take the screen off because I did not want to break it. But.... exposing the screen I did notice that there was a film on top of the screen like a screen protector. I found it odd because our fingers would never touch the actual screen since its enclosed. Well anyways.. I thought maybe this film way the polarizing film causing us the poor viewing angle. So I went ahead and peeled it off slowly to prevent damage to the screen. It took me about 30 minutes of slowly peeling the thing since it was glued permanently. Definitely was not meant to be removed! So anyways... the film was not the problem. All it was is a darker film to reduce the screen brightness. Once the film was off the touch screen would light up very bright white and unusable.Once I laid the film back on top.. then it would look normal. SO.. THATS HOW FAR i GOT LAST TIME. NOW... THIS TIME i WENT A LITTLE FURTHER MORE. Actually.. I went for the whole cake. Encourage by this thread I decided to open up the Touch once more and go all out on it. This time I pulled the whole screen out from the phone. And ripped the screen apart as much as I could and did without damaging it. Ok... so this is whats inside. I will start from the actual glass screen in which we view. Ok heres the stack order,,,....
1: Glass screen
2: thin blurry transparent film
3: another thin blurry transparent film
4: Thick plastic layer (LED's resides on the bottom of this layer)
5: Somewhat of a think plastic metallic mirror like layer.
1 to 5 are enclosed in 2 aluminum housings in which make up the whole LCD monitor.
Thats it... 5 layers of parts. My suspicions from observing the parts was that number 2 and 3 layers were the culprit in which are polarizing the image. It could not be the glass since glass is clear, it could not be the 5th layer since thats is like a mirror and reflect all the bright light of the back light, and it could not be the 4th layer since thats where the actual LED light are and thats what emits all the light. Sooo.. between the 1st and 4th and 5th layers there is 2 and 3. The 2 suspicious films. So ok.. i figured.. let me rig up the batter and turn it on and see how the screen look with out them on. So I did,,,,, unfortunately.. those 2 layers don't come off since they are fused to the actual 4th back light layer. Only way to take them off was to cut them. Of course I didn't do that.. i want to save the phone.
So what i did was to fold them inwards out the way and then see the screen without them in between. So I did..... I finally did. Once both films were out the way.. guess what? The terrible viewing angle is STILL THERE!!!!!! Arrrg!! Sooo close!So next obvious step is to fold everything except the back light layer and see the screen. i di and the problem is still there. :P
So..... ladies and germs...... The conclusion is that the actual problem lays on the actual GLASS screen where the image is processed. So there is no fix but to get a real manufacture proper screen. The actual glass does have one more film on it but that film cannot be peeled off ... otherwise you are peeling off the actual image you see when the phone is turned on. SO that small film that displays the image is actually the culprit. Damn..................... soo close.
Took me about 4 hours of testing.. seeing.... observing... and ripping apart and putting everything back. I learned how to dismantle the phone completely so at least i gained that knowledge. :P . Now.. i just need to buy a can of high pressure air to blue off all the dust inside the screen that stay in there when I opened it up. :P
I hope you all understand that we did get ripped off once more by Sprint of HTC. I don't know who to blame .. but the ones that got the terrible view angle screen are the real suckers. (ME)
