Hi.
I've acquired one lot of a nice front panel modules.

They have a 16x2 LCD, four SPST push buttons and 3
indicator LED's. All on one single PCB with a common
24-pin ribbon cable connector and a contrast adj pot.
Nice unit, I think :-)

I've put some pictures and other information on my web site at :
http://www.st-anna-data.se/front_panel.html
(Note that this page is not currently linked from my
main page !)

I'm asking $12.50 each.
Shipping :
1 unit : $4.00
2-4 units : $6.00
5-8 units : $10.00

PayPal prefered, but other payment methods conceivable...

Tell me what you think !

Best Regards
Jan-Erik.

Nice board...
Anyway, a few questions:
What are the dimensions of push buttons, i'haven't seen them...
Colour / current of led backlight?

It's that kind of "short way" switch with just aprox
1/4 of a mm between the up and down positions.
With a clear "tactile" feeling and a "click" sound.

> Colour / current of led backlight?

No backlight.
I have to add that to the description. Thanks for
pointing that out...

Sorry, tag fault... Outlook = GRRRR

I have forgotten:
Type of LCD (TN, STN, FSTN?)

Well, actulay I don't know. I'd guess from other (undocumented)
information I have "at least" STN. I've also seen "STHC, Super
Twisted High Contrast" beeing mentioned, but can't make sure
that that relates to this particular module...

Is there any way to tell from looking at the display ?

It's a light grey background with dark blue characters.
The size of a single (capital) character is about 5 x 3 mm.

Note that this module was OEM'ed for a large telecom
company, and it's not in the producers (Densitron) basic
product sortiment...

TN = Twisted Nematic. Old-tech, lousy contrast. Black-on-grey.
STN = Super Twist Nematic, aka Supertwist. Better contrast than TN. Used in
 a lot of 486-era laptop displays ("passive matrix"). Usually
 dark-blue-on-grey or dark-blue-on-green, though colour (RGB) STN displays
 are available (or at least they were when I last checked).
TFT = Thin Film Transistor. Used in almost all new laptops and PC LCDs. Good
 contrast, very expensive in comparison to other LCD technologies.
FSTN = Film-stabilised SuperTwist Nematic. Uses an optical retarder to
 eliminate elliptical light polarisation, resulting in a black-and-white
 display. Some monochrome laptop LCDs were FSTN.

There's a lot of info about the different types of LCDs online - for
instance:
<http://www.orientdisplay.com/lcds-basis.html> (very informative)
<www.idwlcd.com/Products/catalog/LCDFeaturesTypes/LCDFeaturesTypes.htm>
<http://www.pacificdisplay.com/lcd_oper_modes.htm>

(found on Google using the searchstring 'TN STN FSTN LCD "twisted nematic"')

> It's a light grey background with dark blue characters.
Probably STN.
