Preferably, the insertion portion has a tapered tip, which facilitates easy insertion of the support post 431 into the through hole. As shown in FIG. 2 , the support pad 432 includes a cylindrical portion and a flange portion connected to the cylindrical portion, the flange portion is connected to the printed circuit board 36 , and the through hole penetrates both the cylindrical portion and the flange portion. FIG. 8 shows four elastic connectors 43 , which are generally respectively located at the four corners of the lower surface of the display 33 and spaced a certain distance from the edge of the display 33 . However, in other embodiments, the number of elastic connecting members 43 is not limited to four, for example, it may be less than four or more than four, which may be determined according to factors such as the size of the display 33 .
