Officejet 8500 LCD question

[ltarjanyi]

I have the same question someone asked before, without answer. Could anyone help?

"

Hi, i want to reuse LCD display from my printer OfficeJet 8500, but I don't know interface LCD with panel. The LCD module has codename SB05444-00_A and the panel, when LCD was mounted is SB05823-00.

Can I ask for schematic diagram of panel or description LCD interface?
This interface has 11 pins, and it looks that is interface with serial data transfer (none-standard interface I guess).

At least identification of LCD driver chip and its datasheet would be a great help. What I can see on the LCD panel, is that only 9 pins are connected to the driver chip. From this 9 it seems that 5 is related to GND, powering the chip and backlight. So 4 is left for communication pointing towards SPI communication. (Also it seems, that the driver chip has at least 110 pins most of them connected to LCD segments.)

Any idea by anyone?
