Response Time: Slower than TFT, may show ghosting in fast motion

Backlight: Often LED or EL; optional for some models

Interface: 8-bit parallel, SPI, or I²C (depends on driver/controller)

Typical Controller: KS0713, SBN1661, or equivalent

Power Consumption: Low – suitable for battery-powered devices

Applications: Industrial controls, medical devices, meters, legacy embedded systems

Note: STN displays offer cost-effective graphical solutions where high speed or color is not required.
