Abstract: The preset invention provides a frame structure, a display device with the frame structure, and a method of fabricating the display device. The frame structure includes a first frame and a second frame. The first frame includes two lateral portions opposite to each other, and a top portion and a bottom portion opposite to each other. A first engaging component is disposed on the lateral portion. The second frame is disposed around the first frame. The second frame includes a top plank and two lateral planks. The top plank is disposed corresponding to the top portion, and the lateral plank is disposed corresponding to the lateral portion. A second engaging component is disposed on the lateral plank. The second engaging component is slidably engaged with the first engaging component. Thus, the present invention can decrease thickness of the frame structure and the display device for preferable aesthetic and low cost.

Abstract: A light guide for a keypad includes a plurality of through hole portions adapted to correspond respectively to keys on the keypad. Each of the through hole portions is adapted to receive at least a part of the corresponding key, and to receive light incident thereinto from at least one light source. Each of selected ones of the through hole portions has a contour with a non-curved contour portion that includes a light incident face and a reflecting face forming an angle with the light incident face. Light incident on the reflecting face is reflected into at least one other through hole portion. The light guide can also be configured to have a tree-like structure.

Abstract: A fabricating method is used for fixing a plastic element to an aluminum alloy element. According to the method, an aluminum alloy forming process is performed for forming an aluminum alloy element made of aluminum. Then, an anodic layer is formed on the aluminum alloy element through an anodic treatment, such that a plurality of micro-holes is formed in the anodic layer. Finally, molten plastic are solidified on the anodic layer through a plastic insert molding. The molten plastic forming the plastic element is filled into the micro-holes of the anodic layer, so as to fix the plastic element on the aluminum alloy element.
