Why LCD display often fused to the glass?
I know several tablets have the LCD display often fused to the glass, why is this done? My research so far leads me to that perhaps this is to assure no dirt gets in between to ruin your tablet experience. Are there any other reasons they are fuzed together, such as to assure the Glass, Touch digitizer and Display screen work better together? I guess I just need some more justification for doing this to a tablet when it is known it will make it more expensive to repair.

How about making things smaller and more compact. With the pieces glued together, one will only have to design one mounting mechanism for the assembly. Otherwise, you would need at least to separate ways of attaching the individual pieces. Tolerances would have to be kept to a very precise level, to guarantee the proper function of the digitizer in relation to the LCD assembly. For as long as slim and sleek sells, designers will have to come up with ways of getting this accomplished. That, in my opinion, is also the reason why adhesives are in favor on newer devices. Definitely a space saver. Of course, that is only my 2 pfennig.:)

There are several convenient reasons for fusing the display to the glass, however the most fundamental reason which would create a better tablet experience is refraction. Or lack of. With two glass panels separated by air, there is a greater index of refraction, meaning that more light is lost within the material, and less reaches your eyes. By fusing the display, the refractive index is less, and the amount of light lost is reduced, and as a result, you get more colours, brighter display, better contrast ratios, etc etc :)
