I'm building a home made flight deck for Flight Simulator. I want to add a couple of LCDs for both the radios and the autopilot panels. I'm not an electronics expert and I have several questions about Matrix LCDs:

- Does LCDs are Reflective, Transmissive or Transreflective? I'd like my panel's displays to be seen in almost any light condition.

- Is it possible to keep an LCD running on both I2C and RS232 protocols? I thought about connecting LCD#1 via RS232 to my PC and LCD#2 via I2C to LCD#1 and that will let me use ONLY 1 serial or USB port.

- If it's not possible, is there a way to handle I2C protocol from the PC's serial ports?

- How does LK404's keyboard connection works? Is there a DIN connector on the display's PCB?

Does LCDs are Reflective, Transmissive or Transreflective? I'd like my panel's displays to be seen in almost any light condition.

It depends on the display. If you use a standard yellow/green backlit one, it will generaly be Transflective.

Is it possible to keep an LCD running on both I2C and RS232 protocols? I thought about connecting LCD#1 via RS232 to my PC and LCD#2 via I2C to LCD#1 and that will let me use ONLY 1 serial or USB port.

Yes, you have to be carefull in the command sending though. But connecting LCD#2 to LCD#1 will not work.

If it's not possible, is there a way to handle I2C protocol from the PC's serial ports?

Not that I know of, for I2C you need an I2C communication card.

How does LK404's keyboard connection works? Is there a DIN connector on the display's PCB

Yes.
