显示电源芯片

显示电源芯片整合多项组件来满足系统电源的需求，包括step-up or step-down pulse width modulation，PWM，DC-to-DC converters，low-dropout regulators，LDO regulators，voltage detectors，operational amplifiers， level shifters或其他零组件。 针对显示屏应用，显示电源芯片提供适当及稳定的电压予source drivers，gate drivers，timing controllers及panel cells; 此外，显示电源芯片的内置过度高温及过载电流保护装置能预防其他零组件于异常状况受到破坏。 持续整合其他零组件于显示电源芯片为目前主要趋势，我们相信显示电源芯片将持续为 TFT-LCD 及 OLED 显示屏的主要零件。
