TFTs / NHD-2.4-240320CF-CSXI#-F minimal wiring for power
« on: July 23, 2015, 12:39:50 AM »
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
