My curiousity got the best of me and the rest is up to you. I did an Image search with Google, defining it by the pic size of 500x375 which is what it said it was when saved it to my pc. Then queried it with "COMPANY LOGO LCD 20 pin", and came up with the following link and 50K examples. YOU get to search them all, good luck hunting!!!

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.
the pc078pyl identity is the name of the chip and apparently there may be several manufacturers, check: http://core-ic.com/quote.php?lcount=2&S1=ON&P1=PC078PYL02
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?
