An image can also burn in on LCD or OLED displays, if a static image is shown for several hours. To prevent this use a screensaver or make a screen inversion after some time, e.g. a day-night operation with inverted colors. In general a white screen is also better than a black one on TFT displays, in terms of image burn-in.
LC-Displays (LCD, TFT) are sensitive against Electrostatic Discharges (ESD). Always make sure that the shielding of displays is grounded (good connection to earth).
