I bought the screen used from a friendly CSer and I believed he had the DS.
Installed it on my DL and it was a perfect fit. The center "o" being right in the center of the split screen.
When I installed on my K100D the "o" was slightly misaligned. Dunno if I **** up OR its just like that. Like I've said, minor annoyance for a whole lotta better view.
To install make sure you have a big rubber blower, plastic tweezer(can be bought from Sim Lim tower), pictorial instructions from DP review(gotta search for it), a clean environment and a bit of patience.
You'll need to lift and dislodge a metal frame from the tab and then the screen is free. Just do it carefully and slowly.
Opps! now the installation seem a bit harder, never mind, 未曾尝试,如何了解。 (how to understand if you dont try), I will try. Thanks for sharing.:thumbsup:
