It all depends entirely upon the make and model of screen, and whether it contains integrated driver electronics or not.
But there's a saying which applies perfectly, "There's no point in re-inventing the wheel". What you want can be done perfectly well using a simple and very cheap (about £5/$5 or €5) electricians LCD or LED multimeter. They're self-contained, battery-powered and just need two wires to be connected. If you want you can gut the working parts from the casing and fit them into whatever you prefer, and even connect a DC power supply to it to replace the battery, but personally I'd just stick an adhesive pad on the back and mount it directly to the outside of your device.
Job done.
