can anyone give me some idea on designing a lcd panel tester? just want to turn on all the pixel of the lcd and manuelly look for non working pixel. able to test Dot character and dot graphics lcd.
There are different types of LCDs, some have drivers and convertors already built-in and can receive serial data, others operate in on a parallel byte of data. Some operate on 5 volt TTL and others on 12 volt CMOS .
am i right to say that i need to create a driver using HD47880 to test the character LCD panel? if yes, can anyone give me some ideas on how to create the driver?
