Designing an LCD Dot Matrix Display Interface - National
Semiconductor Application Note (app note added 2/06) |

Digital pot adjusts LCD's contrast - 02/04/99 Issue of EDN
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..... [Design Idea by Jef Collin, CSE Systems, Turnhout,
Belgium] |

Digital Potentiometer Controls LCD Bias - 03/17/94 EDN-Design
Ideas.....Designers of pen-based computers can easily relegate some
controls that were previously mechanical, such as switches and
potentiometers.... [Design Idea by Michael Cortopassi, Dauphin Technology,
Lombard, IL] |
|
Easily Display Bit Map Images on Small Graphic LCDs - 11/19/98
EDN-Design Ideas.....Combining a high-level language, such as Microsoft
Windows, with low-level assembly code or C++ code allows you to display
perfect bit-map pictures on your small-graphic LCD screen...... [Design
Idea by Todd Fitzsimmons, Densitron Corp, Santa Fe Springs, CA] |

Embedded processor directly drives LCD - 9-Jan-03 Issue of EDN Driving
a bare LCD does not necessarily require specialized interface circuitry or
peripherals. This Design Idea describes an alternative drive scheme, which you
can easily implement using the general-purpose outputs of a microcontroller. Many
embedded-system applications need to interact with a user by displaying simple numeric
or alphanumeric characters..... [Design Idea by Daniel Malik, Motorola, Czech
Republic] |
|
Excel offers painless LCD initialization - 20-Sep-01 Issue of EDN To
display a font or a symbol on an LCD, you need to convert the desired character into
numerical data. Creating the data for an entire font set requires specialized tools;
even with these tools, the task can be daunting. Alternatively, you can build a font
calculator using an Excel spreadsheet..... [Design Idea by Alberto Bitti, Eptar, Lugo,
Italy] |

Fourth Generation of LCD Backlight Technology - AN65 Linear TechnologyThis
publication, LTC's fourth effort devoted to LCD backlighting in as many years, treats
subject comprehensively. The text considers lamps, display and layout induced losses,
circuitry, efficiency related issues, optimization and measurement techniques. Twelve
appended sections cover lamp types, mechanical design, electrical and photometric
measurement, layout, circuitry and related topics. |
