Not So FAQ: Can you use 30 temperature sensors, 200 feet from the PC ?
Here is a not-so-common customer question: Is it possible to measure server temperatures using 30 different sensors, 200 feet away from the computer? Answer: Yes, this possible! Our WRDOWY17 temperature sensor is a natural choice for this type of application. The Crystalfontz 16×2 character LCD with keypad gives an easy serial or USB interface to 32 WRDOWY17 sensors.

e-Paper is Here!
Question: What’s so special about e-Paper? Answer: The key to e-paper is low power. e-Paper Displays Are A Low Power Solution If your project needs a very low-power display solution, a zero-power ePaper display is the answer. First designed to mimic the appearance of black ink on white paper, these electrophoretic display modules are sometimes referred
Tutorial: Driving a 144×32 Graphic LCD
We have published a sample Arduino Sketch that shows how to drive a Sitronix ST7920 based CFAG14432D 144×32 Graphic LCD in our support forum. With just a few primitive functions, you can create some nice looking displays. We used a Seeeduino v4.2. An Arduino Uno would work just as well. Here is a video overview of

The Legendary HD44780 Controller
Modern Character LCD display modules have been possible since 1987 when Hitachi introduced the HD44780 LCD controller. Since then, Hitachi no longer manufactures this integrated circuit (IC), but modern LCD controller ICs make it a point to be HD44780-compatible. Controller Compatibility The character LCD display modules offered by Crystalfontz America Inc. are no exception to

What is the Difference Between OLED, PMOLED, and AMOLED?
Confused about the differences (and similarities) between OLEDs, PMOLEDs, and AMOLEDs? Quick Version: OLED stands for Organic Light Emitting Diode. PMOLED is Passive Matrix OLED — Passive Matrix Organic Light Emitting Diode. AMOLED is Active Matrix OLED. An Active Matrix OLED uses a TFT (Thin Film Transistor) transistor-per-pixel architecture.

AMOLED
AMOLED is Active Matrix OLED. An Active Matrix OLED uses a TFT (Thin Film Transistor) transistor-per-pixel architecture. Using a transistor-per-pixel allows higher resolution displays to be made and avoids the problems associated with high duty cycle passive displays. Detailed Definition In an AMOLED, once a pixel is turned on, it can stay on for the
OLED
OLED stands for Organic Light Emitting Diode. OLEDs are used to make OLED Displays, which can either be PMOLED (Passive Matrix OLED) or AMOLED (Active Matrix OLED). Crystalfontz carries a full line of OLED modules. Detailed Definition What makes OLEDs useful for display construction is that they can be fabricated in bulk. For instance, to
What Makes an LCD Sunlight Readable?
Have you ever been at the car wash in the late afternoon, struggling to read the instructions on the display at the pay kiosk? That may be because it was not a sunlight-readable LCD display. What Makes a Display Readable in Bright Light? There are two ways to get sunlight readability: 1) is to work
