If you want some more information about this issue I can put up a link to my thread where xocomaox helps me out.
Hi,
Did anyone have any luck with fixes? I've just found the same problem in the bottom right of my screen. Swype is now useless as it breaks up my words as if I'm adding a space and when I want an 'm' or '.' it presses all the buttons around it.
I've done many reboots and now just done a factory reset and the problem isn't fixed. With scanning through my apps I've worked out it is all up the right side of the screen and then a 1/3 across the bottom from the right - Down the red line and then across to the Chrome icon.

Just to let you guys know, I got my replacement from Verizon over the weekend and have already sent my old one back. The replacement is great (they claim it's certified like-new, but honestly it looks MINT. I do not see any scratches or marks on it whatsoever. I believe it is open-box new) and works perfectly, so I see that a few are failing and that cable or board seems to be the culprit. Especially since it's losing input on such a precise area of the screen. What you guys are describing is exactly what I was experiencing, only a different area of the screen. (mine has a 1cm band across the exact middle of the phone from left to right that would not register touches)
If you did not buy your phone through your carrier, you can submit a claim on LG's website for the phone and they will email you a shipping label for your phone to send it back. They can repair it for you, but it takes some time. People I have spoken with said it can take 2 weeks or longer to get your repaired phone back.
If your warranty has already expired, you might want to consider repairing the screen/digitizer yourself, as the screen piece comes off quite easily. You can probably take it off and unplug,. plug back in to see if it helps. If not, buying an entirely new assembly with the LCD screen and digitizer already glued together is the most highly recommended option. This is due to the meticulous and difficult task of both separating and gluing the screen back onto the digitizer without compromising either. If you do not have professional equipment to do this, I strongly suggest you spend the extra money and buy the whole assembly together. This is the difference between $20 and $80 but it is worth the piece of mind, believe me.
Also, please be aware that places are selling non-OEM screens with the digitizer attached that are sub-par quality. Always try to get an OEM screen. It will be at least $70.
