Grayscale 160x128 LCD

Fair grayscale image display with extreme low power

This device is one of the best LCDs in the sub-milliamp class. It allows you to draw nice graycale graphics and also to display pictures. As this display has 16 gray levels, dithering is not necessary to display nice picturees. It also allows to display non-alphabet characters, especially japanese kanji or other asian languages character that require a higher resolution dot matrix.
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.
Another advantage is that this display works in 3 modes, parallel, 4-wire SPI, 3-wire SPI. .

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 nicely. We can also provide a PGM reader library (compiled library only).

This LCD is delivered with its FPC connector for your convenience, and an interface board is under design. It will allow to use this LCD on a universal printed circuit (pitch = 2.54mm).

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 10240 bytes (128 x 160, 4-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 3 ms for a complete refresh.

Kit contents

This LCD can be purchased with its connector if you want to make your own board, or with an adaptor board if you want to use it in a hand-wired hardware.
Our product naming conventions are as follows:

LCD is simply called after its part number (in this case PW160128LCD)
The LCD and the connector set is called after its part number, with the suffix SET. (In this case PW160128LCDSET).
Finally, the LCD + connnector + adaptor board set is called KIT (in this case PW160128LCDKIT).
