gkhnyldrm Posted April 30, 2004 Report Share Posted April 30, 2004 i made the lcd project in the main page but it caused short circuit,if you wired +5V to pin15 it causes short circuit. if you want your backligt on,wire the cable to (+) and (-) at the back of the lcd.Project Link: http://www.electronics-lab.com/projects/pc/020/index.html Quote Link to comment Share on other sites More sharing options...
MP Posted May 1, 2004 Report Share Posted May 1, 2004 Pins 15 and 16 are for your backlight on some display types and they are on the side with a couple of characters like K and L or + and -. Also, the voltage needed for the backlight might be +5 volts or -15 volts or anything in between. Different manufacturers use different voltages for the backlight. The first page of the projects advises you to get familiar with your display data sheet. This is because there are more types of displays out there than there are color TV manufacturers. They all have their own way of doing things.From your data sheet: What voltage does your particular display need to run the backlight? You will need to substitute this voltage for the +5V listed in the project. Where does it suggest you connect the wires?If your display does not have a backlight circuit, you might be sending voltage to components on the display's circuit board which are causing this problem.Everything you need to know is in the data sheet for your display. If you do not have a data sheet for the display, you can post a request in the data sheet request area on this site. Someone in this community probably has it or has seen it.If you are in a hurry, just disconnect pins 15 and 16 and go on with the project. You will still be able to see the characters. Just not as well.Also, I am just curious about something. What software will you be using to run the display?MP Quote Link to comment Share on other sites More sharing options...
