Touchscreen film to a 14.1" TFT LCD

[DiTBho]

I have a 14.1" TFT LCD, it's 1024x768 pixel 4:3, and I'd like to add a resistive film on it in order to convert it into a  touchscreen.

If this crazy thing makes sense, is there any place from where you recommend to bought it? and a USB controller for it?

Of course it makes sense everybody is doing it, and the only reasonable price is Ali, the biggest difficulty is the 4:3 aspect ratio, the available 14' are not 4:3, and the available 4:3 are not 14" 

14" but not 4:3

I may try to adapt a 15" film to a 14.1" screen, but in this case I would also adapt the plastic frame around the LCD, and make it half inches larger on each corner


This is the evil plan:

That's the biggest one, somehow 4:3 I've found for you:
