In this thesis, based on Electro-Magnetic theories and principle, we propose a hybrid method to suppress the Electro-Magnetic Interference (EMI) in antenna effect without metal shielding devices. The hybrid proposal uses the suppressing antenna effect rules of EMI technology. Furthermore, the hybrid proposal could meet the EMC requirement; also provide a product cost reduction, better propagation in temperature, and easier fabrication.
In the proposed scheme, we offer a number of methods to reduce EMI radiated emission problems.
1. Grounding (0V reference plane) pattern rebuilding.
2. Using filter and EMI suppressing component technique in the proper positions.
3. PCB layout Modify.
In this thesis, the following contributions are gained:
According to our knowledge, we use hybrid proposal method to lower down EMI radiated emission level without shielding devices from the TFT-LCD Television. We bright out an efficient and economical way to reduce EMI radiated emission level. The experiments show that, we are able to cut off the extra cost, reduce the temperature, and also production easily.
