在一些实施例中，所述预设事件还包括来电或未接来电事件、未读短信事件、日程提醒事件等，处理器4还在确定终端设备100有来电或未接来电事件、未读短信事件或日程提醒事件等事件时，产生相应的电平信号至所述电源开关52而控制电源开关52导通，从而电源51为所述光源33供电，光源33发光而通过所述导光板321及导光柱322导至壳面板1外进行提示。
在一些实施例中，所述壳面板1也可为终端设备100的后壳面板，所述收容孔20设置于后壳面板上，且指纹按键30收容于后壳面板上的收容孔20中。
其中，终端设备1可以为手机、平板电脑、个人数字助理PDA、销售终端POS或车载电脑等等。
从而，本发明中，所述处理器4可在来电或未接来电事件、未读短信事件、日程提醒事件、指纹触摸事件或按键按压事件等事件发生时，控制发光部32的光源33发光，以产生对应的提示。
本发明的指纹按键30、发光提示结构2及终端设备100，可在指纹按键30的区域同时实现指纹按键的功能和提示功能，无需在壳体的其他地方额外设置提示灯等提示装置，节约了设计空间。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
