Control of EMI in Small Size LCD Module

The LCD resolution and the camera video frequency will be higher along with its application in the handset.When the system frequency will exceed 40 MHz,the traditional filter method has achieved their technical limit for suppress EMI and ESD.In order to adapt the increasing of data rate and to display the real time image,a technique was proposed to convert RGB parallel transmission signals to serial differential signal for controlling EMI of wireless and interface circuit.This method can also simplify the interface design.
