160x128 pixels, 20 columns x 16 rows of 8x8 text. White pixels
with blue background |
|
Powered by +5 VDC. But, can connect I/O directly to Propeller
without resistors (at least mine hasn't died yet...). |
|
Controller chip is a
T6963C from Toshiba. SRAM is a 32kB
IS65C256AL.
LCD drivers are Avant SND8080G (four of them). |

|
Notes:
 |
Data bus pins are backwards from datasheet!
Pin#12 is the MSBit and Pin#19 is the LSBit... |
|
Can power backlight from 5VDC. |
|
Can connect directly to Propeller's 3.3V I/O pins. Was
afraid of overloading LCD output drivers, but seems to work fine.
|
|
Just connect Reset line to one end of a 100nF capacitor with the
other end grounded. |
|
Display does generate the required -10V, so just use a 10k or
20k pot to generate the V0 LCD bias signal. |
|
Memory size is 32kB, plenty of room for several text/graphics
screens. Allows for easy scrolling. |
|
Using built-in font, only 20x16=320 bytes required for a text
screen. |
|
Font size is hard-wired to be 8x8. |
|
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. |
|
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. |
