用LED作背光是相当直接了当的,而EL背光对设计师存在太多的秘密。EL背光用到太多的EL控制器和混合电路。尽管这些器件提供对EL面板的良好控制并具有简便的电路接口,但其成本和形状因子在某些应用中可能是不允许的。在这种情况下,便会希望使用一种现有的MCU为EL面板提供驱动信号 LED backlighting is quite straightforward, while the EL backlight has too many secrets to the designer. The EL backlight uses too many EL controllers and hybrid circuits. Although these devices provide good control of the EL panel and have a simple circuit interface, their cost and form factor may not be acceptable in some applications. In this case, you will want to use an existing MCU to provide driving signals for the EL panel
