A large, thin pane of glass is going to bow slightly, more than a smaller pane of glass of the same thickness. Could this be why it has been (possibly) misunderstood as being plastic? Can someone with a little more than the average eye for detail and knowhow, please verify whether it IS indeed plastic, or not?
Then again, maybe it *is* plastic... which is entirely what I am here to ascertain.
I highly doubt that the OMC screen is plastic; let me explain: Aligning my eye with the edge of the handset, so that my field of vision is parallel with the plane of the screen, and with the entire screen angled so as to encourage a full reflection of ambient light upon the surface, I begin to press on the screen with the very tip of my finger, very carefully and very slowly, whilst observing only the point of contact where my finger meets the screen. I have applied considerable pressure, more than any plastic could take without deforming significantly more than the screen on the OMC test sample appears to. The indentation distortion of the screen is extremely minimal indeed. Any plastic substrate, laminate or composite, would have distorted much more than this, given the level of pressure applied, and considering the thickness of the outer layer of the screen can surely not exceed, at the most, 1mm.
Plastic? I think you're wrong, folks. I really do, and my knowledge of production line techniques and material behaviours (much of which is just common sense, and not jumping to poorly considered conclusions), having worked on them, seems to validate that this is, in fact glass, and not plastic.
