Thin-Film Transistors (TFTs) are a type of field-effect transistor made by depositing thin layers of semiconductor material onto a substrate. They are commonly used in display technologies, such as liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs), where they help control individual pixels for better image quality. TFTs offer advantages like flexibility, lightweight design, and the ability to be produced on various substrates, including glass and plastic. Their thin structure allows for high-resolution displays and efficient power consumption, making them essential components in modern electronic devices like smartphones and tablets.
