Low Temperature Polycrystalline Silicon
(Low Temperature PolySilicon TFT LCD) An active matrix (TFT) LCD screen that is more durable and less complex than screens made with amorphous silicon substrates. It allows for densities of 300 dpi and greater, and it is expected to enable all the computing electronics to be built within the screen itself.
The larger and uniform silicon grains of polysilicon (poly-Si) allow electrons to flow more freely than through amorphous silicon (a-Si), which is made up of smaller and randomly sized grains. It allows the normally external driver chips to be fabricated on the glass substrate which dramatically reduces row and column connections.
