Abstract

Introduction Disclosed here is a PCB (Printed Circuit Board) patterning method which is very suitable for PCBs used in LCD (Liquid Crystal Display) module. This method makes it possible to make the PCB very narrow and also the EMI (Electro Magnetic Interference) noise from the PCB be better than traditional patterning methods. Traditional ways and its disadvantages The major LCD module consists of a Liquid Crystal Cell (2 glasses which sandwich liquid crystal) , Driver-ICs which supplies appropriate voltage to the LC-Cell, and PCB(s) which provides the data signal to the driver-ICs. To provide the signals to driver-ICs, via holes are used in PCB to make overhead crossing of each data line across the data bus.
