说明：  非常好的元件应用说明，白色家电的显示出来要求相对较低，使用通用芯片74HC164替代专专用显示出来驱动driver芯片，既可获的相同显示出来效果，又可降低成本，提高系统可靠性.
(Very good application components, white goods displayed requirements are relatively low, the use of general-purpose chip 74HC164 alternative specifically dedicated display driver driver chip, both received the same display effect, but also reduce costs, improve system reliability.)
