UPD16650 Datasheet (NEC) - 120-/128-OUTPUT TFT-LCD GATE DRIVER

UPD16650, 120-/128-OUTPUT TFT-LCD GATE DRIVER

Pin symbol X1 to X128 Pin name Driver output Description of function Output scan signals to drive the TFT-LCD gate electrodes.

The output changes when the shift clock φX rises.

The amplitude of the driver output is VDD - VEE1.

See the timing charts shown later for details of how to switch between th

DATA SHEET MOS INTEGRATED CIRCUIT µPD16650 120-/128-OUTPUT TFT-LCD GATE DRIVER The µPD16650 is a TFT-LCD gate driver.

Provided with a level shift circuit at the logic input, this chip can output a high gate scan voltage for a CMOS-level input.

The µPD16650 has an output change-over function for switching from the 120-output mode to the 128-output mode, and vice versa, thereby supporting the VGA, SVGA, and XGA panels.

Its output enable function (OE) enables installing the driver on either sid
