High Voltage LCD Driver HI-8010 alternative

(1/1)

R_A_F:
Hello,

I'm converting an old piece of avionics for sim use. It has a liquid crystal display with an integrated IC to drive it. The whole thing is pretty simple. Two knobs (dual concentric encoders) and a display. Well due to my lets say carelessness  :-//, I've managed to kill that driver. It's a Holt HI-8010. I've looked everywhere for a replacement, no joy. It's a 30 volt (-30V to 0V) display driver. Link to the datasheet - (http://www.holtic.com/documents/90-hi-8010_v-rev-gpdf.do).

Is there any LCD aficionado here who could tell me if there's a suitable off-the-shelf alternative for such driver? Could I possibly use a VFD display driver and limit its voltage?

Thanks for any input.

Here's a photo of said display:

this part seems unobtanium ??

If you have space you can program a small microcontroller (PIC?) to emulate the shift register and use a totem pole per pin to do voltage translation. Can fit an small board.

I contacted Holt directly as well. We'll see. I was hoping someone would know a possible alternative to that IC. Pretty much all of the mainstream LCD drivers are low voltage.

Thanks. Yeah, if I can't find a replacement I'll have to resort to building my own driver.
