Active-Matrix LCD Bias Supply Operates from Battery Input -
02/03/00 EDN-Design Ideas.....Many active-matrix-LCD applications need
multiple voltages for thin-film-transistor (TFT]bias. Typically, three
voltages are necessary 5V for column driver; a positive
voltage, such as 10V; and a negative voltage, such -5V, for TFT gate
drive, or row driver. For handheld electronic devices, a battery must.....
