Abstract

A method of manufacturing a base includes the following steps. First, a plate is provided. Next, the plate is machined to form a bottom frame. The bottom frame has a bottom portion and a plurality of side walls disposed at the bottom portion. Next, whether the bottom frame is designed for being assembled to a first display panel or a second display panel is determined. The size of the first display panel is different from that of the second display panel. Next, if the bottom frame is designed for being assembled to the first display panel, a pad is formed on the bottom portion of the bottom frame such that a first base is formed. Next, if the bottom frame is designed for being assembled to the second display panel, the bottom portion is punched to form a plurality of barricades such that a second base is formed.

Claims

1. A method of manufacturing a base, comprising:

providing a plate;

machining the plate to form a bottom frame, wherein the bottom frame has a bottom portion and a plurality of side walls disposed at the bottom portion, and the side walls and the bottom portion together form a first accommodating space;

determining whether the bottom frame is designed for being assembled to a first display panel or a second display panel, wherein the thickness of the first display panel is smaller than the thickness of the second display panel, the length of the first display panel is larger than the length of the second display panel, and the width of the first display panel is larger than the width of the second display panel;

forming at least one pad at the bottom portion of the bottom frame such that a first base adapted to be assembled to the first display panel is formed if the bottom frame is designed for being assembled to the first display panel, wherein the first display panel is adapted to be disposed on the pad and located in the first accommodating space; and

punching the bottom portion of the bottom frame to form a plurality of barricades such that a second base adapted to be assembled to the second display panel is formed if the bottom frame is designed for being assembled to the second display panel, wherein the barricades are arranged along the side walls, each of the barricades maintains a distance from the corresponding side wall, the barricades and the bottom portion together form a second accommodating space in the first accommodating space, and the second display panel is adapted to be disposed in the second accommodating space.

2. The method of manufacturing a base as claimed in claim 1, further comprising disposing a buffer between each of the barricades and the corresponding side wall after the barricades are formed.

3. The method of manufacturing a base as claimed in claim 1, wherein the bottom frame further has at least one arc-shaped connection portion, the side walls and the arc-shaped connection portion are disposed on the bottom portion, and the arc-shaped connection portion connects two of the side walls and is bendingly disposed between the corresponding two of the side walls.
