    LCD w/ EL Backlight & source for EL Sheets

    I recently brought an 20x2 LCD w/ el backlight. It came without the inverter attached. The inverter has 4 pins, Vcc (or Vss i dont have the pinout with me at the moment), Ground, AC output, AC Output which are pins 1,2,3,4 respectively. I know what to attach pins 1 and 2 to, but what abt 3 and 4? Any help would be appreciated.

    Also, if you want to buy large sheets of EL for your custom designs, go to http://www.beingseen.com/sheets.html
    They have lots of nice stuff.

    oh and before i get flamed a million times for a small LCD, its for my home box, not in the car.

    pinout..

    Okay, you connect your voltage source to the VCC pin... and ground it to the "ground pin".. I don't know what voltage it needs (probably 5v).

    Then you connect each of the AC output pins to the EL strip wherever is most convienient... if possible I think you'll get more even lighting if you connect the AC output to opposite sides of the EL strip.

    Good Luck,
