Attach lcd panel to Arduino

Projects General Guidance

Hey guys,
I have seen this LCD:

I want to attach it to Arduino, how do I wire it and send data to him?
I have not seen any data on it online, maybe some one have dealt with this model.

Thanks!

You can't drive that kind of display directly from an Arduino (at least, not easily). The segments require a special AC signal that is normally provided by a dedicated LCD controller. Some ASICs that use LCD (such as multimeter, etc.), have the LCD controller embedded in the IC, along with the logic that performs whatever the IC does.

Sorry, but that display requires its specific controller chip. It absolutely cannot be driven by an Arduino without the driver chip.

Driving Mode: 1/4 Duty，1/3Bias

Been there, done that, failed. Display, driver chip, breakout boards, soldering & wiring...

I still have the display & driver chips, now I'm a lot better at soldering SOIC packages (that was a 28 pin chip, iirc), maybe should give it a try again. Though good chance you can find the same display with driver IC on board making life a lot easier. Then it probable works right out of the box.
