Though, for me, the benefits of touchscreen technology far outweigh the occasional need to wipe the display of a device surreptitiously against my trouser leg - for others it remains a real bone of contention. Though perhaps, however, not for much longer...
Famed panel maker LG.Philips has this week revealed it has developed a new type of LCD which it claims is resistant to virtually all forms of dirt and grime and which employs a principle similar to that used on non-stick frying pans, by which it presumably means Teflon.
The result - though apparently untested at a culinary level - means the new LCDs minimise fingerprint marks, dust and dirt and even ink from permanent markers can be easily wiped clean. Even more encouragingly, LG.Philips has a 15.4in notebook prototype built which it hopes to push into mass production early next year.
Understandably, LG.Phillips wouldn't divulge exactly what makes its panels so effective but it did take the time to explain what everyone else was doing wrong:
"TFT-LCD panels usually feature a coating on the surface of the polarizer film, designed to reduce glare and reflections. Because of their chemical properties, some of these coatings have a tendency to hold onto dirt and oil. Generally, to make LCD panels dirt-resistant, manufacturers must add a second coating to the polarizer film in addition to the glare-reduction coating. This is a time consuming process that slows delivery time and adds to the cost of panels. LG.Philips LCD has found a way to eliminate this additional step while also delivering superior dirt resistance."
The proof, as they say, will be in the pudding or - in this case - maybe in throwing the pudding at the screen and seeing how it wipes off...
