Active Matrix LCD Bias Supply Operates from Battery Input: 02/03/00 EDN
Design Ideas / (added 6/06) 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 ....
