Displays can be of two types: thin-film transistor liquid crystal displays (TFT-LCD) or based on organic compounds light-emitting diodes (OLED) that offer high-quality image at low power consumption. LCD and OLED displays incorporate both extremely hard materials (molybdenum and titanium nitride) and extremely soft materials (silver alloys). An SEM analysis of these structures is complicated because of the thickness of glass (or plastic) substrates, organic interlayers, and integral touch screens.
