I have the same LCD with the same circumstances but from my probing I found that:
pin 1~ GND
pin 16&17~ V- for the back light
pin18~ NC (pin space between back light +&-)
pin~19&20~ V+ for back light

I have a seeking suspicion that pin 2 is the LCD power and that the other pins follow a standard LCD module pin-out

Pin 1&2 are ground
Pin 19&20 are Vcc, 5 to 27v
Pin 3to10 should go strait to the chip, a binary counter should tell you what they do.
Pin 11to18 should be functions.
I could tell you more with a better PIC.

That strongly suggests it was a one time special mass manufacture for this
one purpose only.
We will probably never see its like in a future products again.

If it is a device that has to do with communication, look for the FCC # and then go here. http://transition.fcc.gov/oet/ea/fccid/help.html

the pc078pyl identity is the name of the chip and apparently there may be several manufacturers, check:

I think the 02 at the end is becuase it is now the 2nd version.

I have no idea how to match a logo across a world full of corporate logos, but I did several searches for the pinouts based on that chip - all to no avail.

There are only a few mfgs of 20 pin LCDisplays.
Is it feeding a Hitachi chip on the other side ?
Or is it direct from the Taiwan black blob ?
What will you do with the pinout once you have it ?

Why is the manufacturer's name important to you?
