FE0202 does not have any icon on it.. just a 4 digit display..
i understand.. as per the datasheet.. there is no common pin

also.. what does BP and L stands for? no pin info is given.. strange..

shyam thats the display controller.. its not difficult to use that LCD.. just no pin description.. coz as per i know.. these kind of LCD do have common pins just like 7-seg displays.. but no description on datasheets.. i checked 3 datasheets for FE0202..

maybe TPS can help?
