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... |
