Is it possible to interface a Hitachi LMG7131PNFL (2-1/2" X 3") LCD screen?

Other Hardware Displays

The other day I got a Hitachi LMG7131PNFL screen out of a Fluke DSP-100 cable meter.
What I am wondering about is the pin layout (the regular 16 pins) and if the protocol of the chips are the same.

On the back of it there are in all 8 chips:
3- HD66284BTF chips
3- BD66285BTF chips

  • are the main ones

Here are some pictures:

Is the pin layout just like any other HD44780 or is it different? LiquidCrystal lib.?
Any help at all would be greatly appreciated.

Extraordinarily unlikely!

Far too many chips for a start. Is the display actually multi-line alphanumeric?

Have you a datasheet?

(If not, that's the end of it!)

That is a passive display with no memory or smart controller. These kind of displays exist with an integrated controller like the Toshiba T6963C which has memory for graphics and text. The raw display is very hard to drive from an Arduino, let alone the display with the T6963C is pretty complicated to use, and requires almost all the pins of an Arduino Uno.

My best recommendation is to get a newer and more accessible display.
