Thanks! Got it working  :D There was a short I didn't catch tucked near the FFC.

Hey Saurabh_B,

Thanks for your help. I did leave the cathodes floating on accident, but when I connected them to the ground the screen still remained black. Does the microcontroller driving the LCD need to be initialized to power the backlight? Thanks for the advice on the parallel connection and Reset pinout too!

Hello Paul,

I'm also looking at a variety of New Haven LCDs for a project. I read that you stated that if a datasheet states the connector should be hot-bar soldered it cannot be used with a FFC ZIF connector. Is this because of an electrical issue or there just aren't surface mount connectors for it? Thanks for your help.

Best,
Jesse Enjaian

Hello. I'm trying to setup a development environment for this LCD. I read in another thread that a 2.4-240320 series LCD could tie VDD, IOVDD, and the backlight anode together at 3.1v instead of having to step down for VDD and IOVDD. I believe I did so (I've attached a CAD of the PCB with a FFC connector where the left most pin is 1 and the bottom pins are all ground) for this LCD as well, but the screen remains black when I hook it up to a voltage generator at 3.1v. I also tied RESET and IM0 to VDD to be high without any pull-ups at 3.1v. Does the problem look mechanical or did I wire something incorrectly? Thanks so much for your help with this.

Best,
Jesse Enjaian
