  • Touchscreen PS2 Adapter, EZscreen L@@K

    I recently purchased an LCD that had a built in touchsceen, but no touchscreen controller , I wanted to know what those 4 pins did. After research I found that they are axes (x1, x2, y1, y2) but I couldn't find out how to wire then into ps2 or Serial, until I came across this.

    My question is if I were solder the 4 pins to the pins located on the ps2 device, and load thier drivers would everything work as normal. Is this a fix to possible touchscreen problem, or is there a way I can wire one of theses ps2 boxes myslef. Please let me know ASAP.

    I highly doubt that would work. If you could just plug the 4 pins into the ps2 port, why would they have touchscreen controllers?

    The 4 pins are are just power in and out for the x and y axes. The controller calculates the position based on the resistance on the x and y axes, and calculates the position and emulates a mouse.

    Like LCD screens, the controller is the expensive part

          Just got off the phone with EZscreen, and they claim that if a Touchscreen is Analog Resistive and not Analog Matrix, the ps2 and serial controller will work . This is great news for anyone who is looking to fix older touchscreens. Just thought I'd let you all know.
