LTPS LCD
(redirected from LTPS TFT LCD)

    0.01 sec.
LTPS LCD
(Low Temperature PolySilicon LCD) An active matrix LCD screen that is faster and more integrated than screens made with amorphous silicon substrates. Rather than the single-crystal silicon used in chips, amorphous silicon advanced the active matrix industry by allowing thin film transistors (TFTs) to be deposited on large substrates. There is a huge investment in existing amorphous technology; however, polysilicon provides an alternate approach for certain applications.

Faster, Denser, More Integrated
The larger and more uniform grains of polysilicon (poly-Si) allow electrons to flow 100 times faster than they do through the random-sized grains of amorphous silicon (a-Si), enabling higher resolutions and higher speed. In addition, instead of surrounding the screen area, the row/column driver electronics are integrated onto the glass substrate, thereby reducing the TFT section and the wiring between the pixels. Thus, LTPS LCD pixels can be closer together and achieve densities of 200 dpi and greater. See LCD and polysilicon.
