I was just thinking if it would be possible to change the whole Touch HD screen to a capacitive screen just like on the iphone or would this be impossible? because you can get your screen changed if there is a crack so why not make it a capacitive screen.
no you can't.
you'll have to provide drivers into the spl and that's kind of impossibile.
apart from drivers, you also need to change the hardware, it's not simply plugging in a screen.

Hi,
Recently ive repaired a HTC Universal, put it back together as best as i could.
Now when i do touch the screen with a stylus, the screen has funny colours behind it. It kind of like when you touch/ prod your Computer LCD. It only happens when theres pressure on the screen so its not really a huge problem. The touch screen is definately there cause when i tap the screen it responds (e.g i tap start and the menu pops down).
If its normal then i can take it, but if its not im complaining to the ebay seller.
This doesent happen when i put any form of pressure on my HTC magician LCD, so im curious.
Let me know what happens with your universal
Cheers,
Whitemoo.
This is not normal behaviour of any touchscreen device!!
hmmm... well i just looked at the broken lcd screen, and even though the LCD itself is shattered, the touch screen is in perfect nick.
I put pressure on the touch screen and couldnt see any of the symptoms i saw on my current LCD
You guys recon i should swap the touch screen over? either way im complaining to the sellers, DODGY.
whitemoo.
from my knowledge, im pretty sure its normal. it happens sometimes on my 9000 so yeahh....
Hi there!
I'm having issues while coding for my Evo. While touching the screen, the Evo interprets me touching the buttons as another press on the screen instead of a onKeyDown, onBackPressed, etc. (It actually sets the MotionEvent pointer count to 2, and I can get the co-ords that I'm touching that are off the main screen, for example, 830*190 when touching the back button.)
Short of coding in the locations of the buttons (which would be different for every phone with capacitive buttons, if they all have the same issue), is there any way to get around this? Does anyone else have this issue with a different capacitive buttoned device?
The nexus has the same problem. It seems that the buttons are a extension of the actual screen. Multitouch doesn't support more than 2 touches on HTC phones. And even that is problematic because the phone registers actualy one big touch and determines the fluctuations in its size. So if you want to pinch to zoom for example the phone will compare the size of the touch between your fingers. Basically you've got a hardware limitation and there's nothing you can do about it.

well my htc hd2 is using android and using it a year by now and notice that the upper left of the screen is not working?is it the lcd or digitizer or just need to align it?i dropped this many times(up to 5 times i think)but no damage on the housing and it looks new,and it is annoying in some games cause it wont work and i notice a very little red dot on that part.....pls help
If you lost sensitivity and the screen does not respond to touch, then it's a digitizer, if picture is distorted or, as you describe, a red dot appeared where it shouldn't be - LCD, sounds like both in your case. I am not quite sure how it doesn't work in games or whether the problem is present in normal screens. Alignment is a procedure to tune and correct mistakes in touch recognition or to make touch more precise on resistive screens.
I suggest replacement of your LCD + DIGITIZER. Dropping it many times may have caused it too, even if housing looks perfect.
They say the screen is 4.7 but also advertise on screen buttons and for some reason the screen just looks smaller than 4.7 inch. The buttons always seem to be there, it's my understand that on screen buttons means that when they aren't needed that they go and that part of the screen that was dedicated to those buttons returns to normal function. I've seen no proof of this however and was wondering if they're just dedicated buttons and it's being called on screen so they can make the screen larger in the spec sheets? Or if the screen is 4.7inch and those buttons are nothing to do with the visible screen size?
Thanx.
The buttons go away during full screen videos, and other apps that use full screen mode (like many games). The screen itself is not smaller than advertised, you're just getting a slightly lower resolution than advertised, when not in full screen mode
In that if a tablet has a resistive screen can you change it for a capactive screen, if it is obviously the same size and the connector are the same?
Just curious as have an old resistive screen tablet which is cracked but no replacements are available.

Unfortunately no you can not, the electronics are different as is the actual sensing screen itself. Typically the cap sense might be connected/communicating to the main processor via an I2C bus, resistive might also (you can find chips that handle either cap sense or resistive screens), potentially given a lot of work (I have done this once) you can substitute a cap sense screen and interface chip for the res screen and interface chip by intercepting the comms bus between screen interface and processor - this requires extensive redesign and build so for typical commercial items it is not really on.... sorry.
