摘　　要：本文深入探讨了液晶电视接口在热插拔过程中遇到的浪涌问题,并详细分析了浪涌过压、浪涌过流以及接地不同步等三大失效模式。为应对这些挑战,文中提出了相应的解决策略:通过TVS器件有效抑制浪涌过压,串接适当阻值的电阻减轻浪涌过流影响,并通过金属结构外壳设计、长短引脚设计及引脚功能排序等方法解决接地不同步问题。这些措施旨在提高液晶电视接口的稳定性与可靠性,确保热插拔操作不会对设备造成损害。This paper deeply discusses the surge problem encountered in the hot swap process of LCD TV interface,and analyzes three failure modes in detail,such as surge overvoltage,surge overcurrent and ground unsynchronization.In order to cope with these challenges,the corresponding solution strategies are put forward:TVS devices can effectively suppress surge overvoltage,connect appropriate resistance values to reduce the impact of surge overcurrent,and solve the ground unsynchronization problem by metal structure shell design,long and short pin design and pin function ordering.These measures are designed to improve the stability and reliability of the LCD TV interface and ensure that the hot swap operation will not cause damage to the device.
