Grayscale 128x112 LCD

This is another low power consumption graphic LCD kit, very useful for low-power hand-held devices. This LCD is used on Soroban. We can provide source code demonstrating how to use it. Although the source code has been developed on MSP430, this LCD can be used with any processor. This LCD works only in parallel mode (8 bit). On the other hand, transfers are a lot faster than a serial device.

Advantages over other displays

You can display a lot more information. For instance with 5-pixel wide characters and 1 pixel space, you can display 8 lines of 17 characters.
This display has a grayscale capability, which allows you to display for instance 2 curves on the same graph.
It's a graphic module. You can display your company logo without requiring a custom design.
4-level grayscale allows you to display images as long a you use dithered files.

This LCD is delivered with its FPC connector for your convenience.

Typical applications

You can use this display for low-power measurement devices. It allows you to display graphics (bargraphs, curves) without taking too much CPU power. As it has a grayscale capability, you can also display more than 1 curve on the same graphics. Its total internal display data is 3584 bytes (128 x 112, 2-bit per pixel). A smart way to refresh it is to use a DMA (in which case you need the same amount of RAM in or around your MPU). At 4 MHz DMA clock, it would take about 1 ms for a complete refresh.
