摘要： In order that a boost converter of an LDI can reduce electromagnetic interference by generating a panel driving voltage through the use of a variable frequency, while achieving a stable boosting operation using the same frequency whenever each frame begins, an oscillator generates an oscillation signal having a frequency, which varies in a predetermined pattern or hops in a random pattern around a center frequency, and generates an oscillation signal having a preset fixed frequency whenever each frame begins.
摘要翻译：为了使LDI的升压转换器可以通过使用可变频率产生面板驱动电压来降低电磁干扰，同时每当帧开始时使用相同的频率实现稳定的升压操作，振荡器产生具有频率以预定模式变化或以围绕中心频率的随机模式跳跃，并且每当帧开始时产生具有预设固定频率的振荡信号。
