I'm having a board made to drive this LCD for a product we're developing. The board designer said it would cost a lot less if we could provide a schematic of an existing board that drives this LCD. Our board is based on a PIC microcontroller but it should be pretty much the same for any microcontroller.

The full part number is: F-51854GNFJ-SLW-ABN.

The LCD uses a Seiko Epson S1D15714 controller.

Thanks,

What 'schematic' do you mean? The datasheet is right there on the website. 8-bit or serial interface can be used.
But that SED is not supported by LCDinfo, if that's what you mean.

I was looking for a schematic of a board based on a microcontroller (PIC preferred) that had a connection for this LCD. I didn't realize this site was for discussing the LCDInfo software, I though it was a generic LCD info site.

I'm hoping you can still help me though. I know very little about electronics, though I've been programming for years. This particular LCD has a 20 pin connector (page 13 of the specifications). Most of the pins connect directly to the microcontroller. What I'm unsure about are the power pins. There are four, Vss (ground), Vdd (+5V for Logic), Vout (DC/DC voltage converter output), and V3 (power supply for LCD Drive). I'm ok with Vss and Vdd, but I know these LCD's require a boosted negative voltage for the LCD Drive. Do I just have to connect a variable resister between Vout, V3 and ground? Or do I need to do something to invert and boost the voltage?

Thanks for any help you can provide.

No problem for discussing generic LCD topics too. There are separate areas for LCDInfo discussion and then also generic hardware and development areas.



I checked the datasheet and looks like the display uses positive lcd drive voltage. So no need for inverting or anything like that.

Just connect a variable resistor to Vout, V3 and GND like you said.
