…with the letters being of the same color as the backlight. LCDs are not subject to screen burn-in like on CRTs. However, LCDs are still susceptible to image persistence. Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of indium tin oxide (ITO), and…
