The segmented piece comprises a first panel surface, and a second panel surface which is connected with and relatively perpendicular to the first panel surface; the fixing structure is a fixing snag arranged on the second panel surface, the butting structure is a fixing hole which is arranged in the second panel surface and corresponds to the fixing snag, and the fixing snag is of a wedge structure. The edge of the LCD panel is butted and limited by a positioning snag of the segmented piece constituting the front frame. The first panel surface of the segmented piece is further provided with a positioning hole(s), and the positioning snag of the segmented piece constituting the front frame is inserted in the positioning hole of the segmented piece constituting the middle frame.
The aim of the invention is further achieved by the following technical scheme. An LCD device module comprises a frame; the frame comprises a plurality of segmented pieces constituting the frame; the frame comprises a front frame, and a middle frame; the structure of the segmented piece(s) constituting the front frame is the same as that of the segmented piece(s) constituting the middle frame.
Preferably, the segmented piece is provided with a fixing structure(s), and a butting structure(s) used for matching with a fixing structure(s) of another segmented piece, and the segmented piece constituting the front frame is matched and fixed together with the butting structure of the segmented piece constituting the middle frame by the fixing structure. The middle frame and the front frame are fixed together by the fixing structures and the butting structures arranged on the segmented pieces; thus, the front frame is fixed on the middle frame.
Preferably, the segmented piece comprises a first panel surface, and a second panel surface which is connected with and relatively perpendicular to the first panel surface; the fixing structure is a fixing snag arranged on the second panel surface, and the butting structure is a fixing hole which is arranged in the second panel surface and corresponds to the fixing snag. The matching mode of the fixing snag and the fixing hole is suitable for assembly, and has simple assembly process, and high efficiency.
Preferably, the fixing snag is of a wedge structure. The snag of a wedge structure is easily inserted in the fixing hole, and is conveniently compressed in the fixing hole.
Preferably, the first panel surface of the segmented piece is provided with a positioning snag(s), and the positioning snag of the segmented piece constituting the middle frame is butted on the LGP of the LCD module. The LGP is positioned by butting the LGP through the snag of the segmented piece, and the structure of the snag is simple.
Preferably, the edge of the LCD panel is butted and limited by the positioning snag of the segmented piece constituting the front frame. The edge of the LCD panel is butted and limited by the positioning snag; the structure of the snag is simple, and assembly is convenient.
Preferably, the first panel surface of the segmented piece is further provided with a positioning hole(s), and the positioning snag of the segmented piece constituting the front frame is inserted in the positioning hole of the segmented piece constituting the middle frame. The positioning snag is inserted in the positioning hole; thus, the segmented piece can be better fixed on another segmented piece, and the segmented piece constituting the front frame can be accurately positioned and assembled on the LCD module.
A frame of an LCD module comprises a plurality of segmented pieces constituting the frame. The frame comprises a front frame, and a middle frame; the structure of the segmented piece(s) constituting the front frame is the same as that of the segmented piece(s) constituting the middle frame.
Preferably, the segmented piece is provided with a fixing structure(s), and a butting structure(s) used for butting with the fixing structure of another segmented piece, and the segmented piece constituting the front frame of the LCD module is matched and fixed together with the butting structure of the segmented piece constituting the middle frame of the LCD module by the fixing structure. The middle frame and the front frame are fixed together by the fixing structures and the butting structures arranged on the segmented pieces, and then the front frame is fixed on the middle frame.
Preferably, the segmented piece comprises a first panel surface, and a second panel surface which is connected with and relatively perpendicular to the first panel surface; the fixing structure is a fixing snag of the second panel surface, and the butting structure is a fixing hole which is arranged in the second panel surface and corresponds to the fixing snag. The first panel surface of the segmented piece is provided with a positioning snag(s) and a positioning hole(s), and the snag of the segmented piece constituting the middle frame is butted on the LGP of the LCD module; the fixing snag of segmented piece constituting the front frame is inserted in the positioning hole of the segmented piece constituting the middle frame, and the edge of the LCD panel is butted and limited by the positioning snag of the segmented piece constituting the front frame. Both the functions of the front frame and the middle frame can be achieved by using the segmented pieces of the same structure. The segmented pieces have the advantages of simple structure, and low production cost.
Because the front frame and the middle frame of the LCD module of the invention are comprised of a plurality of segmented pieces of the same structure, the segmented pieces constituting the front frame can be superposed outside the segmented pieces constituting the middle frame, and then the front frame and middle frame of different sizes can be respectively formed. Thus, because the segmented pieces constituting the front frame and the middle frame are of the same structure, the segmented pieces can be produced by only one mold, and the front frame and the middle frame can be produced just by the same mold, thereby saving the production cost. In addition, because the front frame and the middle frame are segmented, and the segmented pieces are of the same structure, the segmented pieces are cut only on one section without singly producing each segmented piece, and segment pieces of different sizes can be cut in accordance with LCD modules of different sizes, thereby further reducing the production cost of LCD modules.
