Displays
|
A screen is a major accessory for the boards.
With colour and touch, it provides a powerful and interactive interface to the sketches. |
Monochrome LCD
|
Monochrome LCD provides an easy introduction to displays.
My first display was a 4 lines by 20 characters LCD with I²C connection. It is very easy to interface and doesn't require a large broadband to operate. I'm still using it for my fischertechnik models. Similar monochrome screens offer a 128 x 64 graphic area. Most of the times, they operate at 5 V and are being replaced by OLED displays running at 3.3 V. |

TFT Screens with Touch
|
The most common option is TFT screens. They come with 8- or 16-parallel bus for data and 4 pins for commands, or with SPI or I²C protocols. Options include resistive or capacitive touch, and haptic feedback.
Most of the time, the LCD controllers feature basic pixel management. However, some controllers are full GPUs, with elaborate graphic primitives and embedded fonts. |

E-Paper Displays
|
The TFT screens face two major concerns: power consumption and readability.
To cope with those concerns, the very interesting e-paper displays technology brings both ultra low power consumption and improved readability. |
