Hi all, Does anyone have a datasheet for a :- Panasonic LNP175011 LED Display Panel ?
Its a 32 by 16 dot matrix display of 5mm tri-color LEDs. Used in scrolling LED signs etc.
On the PCB are 2x 32-bit shift registers, 2x 3to8 decoders, a timing IC, and lots of transistors for driving the rows and columns. There are adjustments for (presumably) red and green brightness. I think the shift registers drive 32 red columns and 32 green columns, then I guess the decoders select the row. Not sure about the timing though. Data gets in via a small IDC connector, and further displays can be daisy-chain connected (Each board has an IN and an OUT connector, plus power)
The only data sheet I can find on the web is a 1 page description of power supply details (5v) and dimensions. No data format, pinout, timing spec etc. Can anyone else shed more light on it?
Many Thanks, Andrew
