Actually in my unit (rebirth) the touchscreen is not very good in that it doesn't react when the pressed area is large (i.e. when using a finger). It works only with the stylus or if I bend my finger to use the nail, which is not always comfortable or possible. It would be nice if the Pyra screen didn't have this flaw (I had several devices with resistive touch screens, and none ever behaved like that).
Yes, that was one horrible batch of touchscreens... we immediately switched to different ones after them.
Now things become more interesting.
I removed a (cracked) touchscreen from one of the LCDs I had lying around and put it in front of various screens (Pandoras LCD, computer monitors, etc.)
It was perfectly fine, as good as on the Pandora.
I haven't tested that one on the Pyra yet, as I got it at home and I'm at work right now, but I will do that tonight.
What I need to find out is whether it was the same touch or not.
We had multiple versions:
* One version which was too hard to press
* Another one which worked find for us (the one we approved).
If the model number on the touchscreen is accurate (it should be!), then it should be one of the ones we approved!
However, we received 4 samples back then which we used to approve.
After that, we received 20 displays, fully assembled.
The one I now tested is one of those 20.
So, what does that mean?
- ... the approved sample might be fine and the later delivered ones are different
- ... the grain of the touchscreen might hit exactly the dpi size of the LCD, leading to the grainy picture
- ... the one I've removed right now is from an older batch but has the same model number
[doublepost=1458561446,1458560578][/doublepost]Okay, just did some more tests, as I remembered I got a GPD XD here which has a similar resolution.
In fact, the issue is the high resolution!
Both the Pyra and Pandora touchscreen look that bad when I put them in front of the GPD XD screen!
The grain exists because we wanted a matte screen (I don't really like glossy), but it seems that's not possible anymore with that high dpi.
So the solution is probably to use a non-matte touchscreen with some AntiGlare to prevent all those reflections.
