碩士 === 明新科技大學 === 系統晶片與嵌入式系統產業研發研究所 === 98 === The technology of the semiconductor industry and the ever-changing electronic products used in the implementation of the microprocessor and its peripheral circuits are increasing at a fast pace. It is developing a wide range of 4C (computers, communications and consumer electronics and automotive electronics or “CarTronics”) devices such as integrated systems, bringing life to facilitate the interests of human beings considerably. This includes Liquid Crystal Displays (LCD). LCD is an outstanding, lightweight devise which is widely used in a variety of portable electronics and television domains. It is universally accepted by consumers and has been replacing the traditional Cathode Ray Tube (CRT) related product applications. However, the multi-function LCD is gradually upgrading and this is accompanied by a worsening problem of the complexity of the Electromagnetic Compatibility specification design (EMC). Due to the latter, Electromagnetic Compatibility issues of electronic products has become an important element of validation. In the text, LCD panels have deliberated on the circuit design for Electromagnetic Compatibility, in line with the actual case of such research. The first part of the circuit architecture for the LCD panel designed to meet the Electromagnetic Compatibility for out theories, meets EMC requirements of the design point. The second part of the LCD panel circuit goes through the conduct Electromagnetic Compatibility measurement volume. The use of the relevant Electromagnetic Interference(EMI), countermeasures the circuit for the LCD panel of EMI test items affected by the volume measurement analysis results of the system.
