Hello all,

i m not sure if it's the right forum . n way we have practical problem with the LCD testing.

We have a segmented LCD of size 65mm x 60mm size with 288 segments (number and different symbols). Now after mounting on the card , how to test and confirm all the segments are glowing ?

one i thought of is to capture the image(how?) of lcd with all segments on and compare it with saved image of all segments on.

But how to take the image ? should this be done in jpeg format or bmp file ?


please help me out. Thanks.
