The invention provides a display method of grouped function option image, which includes certain function option programs and a relative image database in an electronic device EMS memory, each function option program is started by triggering of an events signal respectively, the relative image database stores certain pre-set unit images and indicates to at least two unit images according with pre-set function of various function option program, and combines into a relative image group. The method detects the events signal firstly, and executes the function option program corresponding to the events signal. Next, the unit image indicated by the pre-set relative image group of the function option program is selected in the relative image database, and combines into the combination image. Finally, the combination image is showed on the display.
