Sparkfun's Graphic LCD 160x128 HUGE

bullet

 

bullet

160x128 pixels, 20 columns x 16 rows of 8x8 text.  White pixels with blue background

bullet

Powered by +5 VDC.  But, can connect I/O directly to Propeller without resistors (at least mine hasn't died yet...). 

bullet

Controller chip is a T6963C from Toshiba.  SRAM is a 32kB IS65C256AL.  LCD drivers are Avant SND8080G (four of them).

Docs:  display datasheet, user app note, Toshiba app note.

Here's my Spin driver and test code

Notes:

bullet

Data bus pins  are backwards from datasheet!   Pin#12 is the MSBit and Pin#19 is the LSBit...

bullet

Can power backlight from 5VDC.

bullet

Can connect directly to Propeller's 3.3V I/O pins.  Was afraid of overloading LCD output drivers, but seems to work fine.

bullet

Just connect Reset line to one end of a 100nF capacitor with the other end grounded.

bullet

Display does generate the required -10V, so just use a 10k or 20k pot to generate the V0 LCD bias signal.

bullet

Memory size is 32kB, plenty of room for several text/graphics screens.  Allows for easy scrolling.

bullet

Using built-in font, only 20x16=320 bytes required for a text screen.

bullet

Font size is hard-wired to be 8x8.

bullet

Set text and graphics area widths to 20, the number of columns.  This way, text will wrap properly.

4D Systems sells many types of OLED displays.  These displays offer high resolution in a small size with low power consumption.  They also sell VGA adapters, USB-serial converters, and a few other interesting things.

bullet

One interesting product is the ľOLED-96-PROP

Parallax has a contest ending April 30, 2008 to develop a bitmap showing code for this device.
