The FPD93140 is a Low Power Gate Driver with Power Supply for Small Format LCD Displays. The FPD93140 and the companion FPD94128 (Controller / Column Driver with Integrated Frame Buffer) form a complete 2-chip solution for driving TFT LCD panels containing up to 176RGB X 240 pixels with versatile mounting and scan options. Its function is to drive the gates of the LCD active matrix displays and to generate all the supply voltages necessary for display operation. A shift register activates rows sequentially in programmable sequences based on the external clock. On chip charge pumps require a minimum number of external capacitores to generate all the necessary voltages to power the FPD94128 Column Driver and drive the LCD rows. Under command from the FPD94128 series Column Driver, the FPD93140 can drive from 2 to 240 rows. This allows the use of various display sizes and Partial Display modes to reduce power consumption.
