Active Matrix LCD Bias Supply Operates from Battery Input:  02/03/00 EDN Design Ideas  /  (added 11/05)  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, ....

Digital Pot Adjusts LCD's Contrast:  02/04/99 EDN-Design Ideas  / (added 6/06)   You can use a digitally controlled potentiometer for many purposes. In this example, you can use the device to regulate the contrast of a standard (such as two lines by 40 characters) LCD. You can use the circuit in Figure 1 in a portable test system, in which you need to change the contrast of the LCD as a function of the viewing angle. You choose the contrast setup from a menu and then use up or down buttons with µC IC1 to adjust the contrast. The µC stores the contrast value in the digital potentiometer, IC2. This design uses a Xicor 10-k unit (dubbed "EEPOT"), but you could use other devices in the design.  The EEPOT connects to the LCD's VO line. You could connect....

Digital Potentiometer Controls LCD Bias:  03/17/94 EDN-Design Ideas / (added 11/06) Designers of pen-based computers can easily relegate some controls that were previously mechanical, such as switches and potentiometers, to on-screen icons. For example, the circuit in Fig 1 shows one way that digital logic can control the -24V-dc LCD bias using two general-purpose I/O command lines. The DS-1669 from Dallas Semiconductor...
