I VIII. New description: ' 【New technical field of the art】 】 This creator relates to the frame structure of a panel of a display, in particular to a frame member and a frame member which are mutually lapped by a relatively reduced thickness The new frame structure with the corresponding concave and convex shape to align the positioning. [Prior Art] _ Check, general thin display such as LCD display or PDP display, etc. 'Metal frame for fixing the panel and backlight module. The large-area metal sheet is stamped and formed, that is, the entire sheet metal sheet is integrally cut, and the remaining part of the frame is completely cut off. In addition to the advantages of no need for positioning, the conventional molding method has the disadvantages of costly materials, high cost, and excessive stress in the form of one-piece stamping to make the flatness poor. In order to save consumables and reduce costs, as shown in Figures 1a to 1c, it is reproduced from the Republic of China New Patent Bulletin No. M26 00 81, which discloses an "improvement of the LCD panel frame". The utility model mainly comprises a frame body (24) which is composed of two L-shaped workpieces (22) or four long-length workpieces (32) but is arranged vertically around the outer frame of the frame body (24). There is a bend in the direction. Wherein, the two L-shaped workpieces (22) or the four elongated workpieces (32) are joined by a vertical plane joint (as shown in the first and the lc diagrams) or a beveled joint (as shown in FIG. 1b). Wait. The disclosure uses a workpiece cut into an L-shaped or a long strip to be docked. Although it can save part of the consumables and reduce the cost, the butt joint method is not easy to accurately position, so a step is often formed at the joint, so that the plane is made. Degree and M285175 The texture of the joint is not good. [New content] The main purpose of the present invention is to provide a frame structure of a novel display panel to improve the disadvantages of the prior art in forming a step at the joint, and the flatness and texture are not good. In order to achieve the above and other objects, according to the frame structure of the display panel of the present invention, a rectangular frame having a receiving space is formed by a plurality of frame members for mounting a panel and a backlight module, etc., wherein the frame member and the edge are included The frame members are overlapped with each other at the ends, and a contiguous surface of a relatively reduced thickness is formed on the end portions, and a corresponding concave portion and a convex portion are respectively formed on the overlapping surfaces thereof, Connected to each other. According to the present invention, the plurality of frame members are arranged in different directions by the stamping technique, and the stress is sufficiently released, so that the flatness after molding is excellent. This is the main purpose of the creation. According to the present invention, the frame member and the frame member are overlapped with each other by a lap joint surface of a relatively reduced thickness, and the corresponding concave and convex portions are aligned and positioned so that the interface between the frame members has no difference. Positioning is accurate and easy to assemble. This is another purpose of the creation. According to the present invention, by using a plurality of frame members to be joined separately, the consumables can be minimized, and the cost can be reduced relatively. This is another purpose of the creation. The embodiments of the present invention will be further described with reference to the embodiments. The embodiments are merely preferred examples, and are not intended to limit the implementation of the present invention. Get the best understanding. First, the frame structure of the present display panel is used for a thin display such as an LCD display or a PDP display to fix a metal frame such as a panel and a backlight module. According to the frame structure of the present invention, as shown in Figures 2a to 2e, a plurality of frame members 1 〇 form a rectangular frame 1 having a receiving space 1 a, for example, four equal-length frame members are required according to design. i 〇 constitutes an equilateral rectangular frame, or a pair of long frame members 10, and a pair of short frame members 1 〇 constitute a rectangular frame or the like. Wherein, the frame member 1 〇 and the frame member 1 系 are overlapped with each other at the ends, and a contiguous surface 1 1 of a thickness of 1 /2 is formed on the adjacent end portions thereof, and the lap joint is formed. Each of the faces i is formed with a concave portion 1 1 a and a convex portion 1 1 b having a shape corresponding to, for example, a semicircular shape; and a corresponding eye 1 2a and a pin 1 are respectively provided on the overlapping surface 1 1 2b, the lap joints 1 1 can be accurately positioned and connected to each other. Further, at the outer side end of the frame member 10, a vertical portion 13 is formed in the thickness direction to define a housing space 1a. According to the present invention, the overlapping faces 11 are joined by, for example, spot welding, solvent, adhesive or gluing. In the embodiment of the above 2a to 2e, the vertical portion of the plurality of frame members is first. After stamping, it is joined into a rectangular frame i. The 3rd to 3d drawings show another molding process of the inventive frame structure. As shown in Fig. 3c, the frame member 丨〇, 1 〇 is joined to a frame and then passed through the punching machine. The tangential line 2 cuts off the excess portion and punches out the vertical portion 13 to form (as shown in Fig. 3d). Figures 4a and 4b show the forming process of the original frame structure with a single frame member. In Fig. 4a, the 'M285175' on both ends of the frame member 1 has a relatively reduced thickness. The joint surface 1 1 and the lap joint surface 11 are respectively formed with a semi-circular concave portion 1 1 a and a convex portion 1 lb corresponding to the shape, and corresponding rims 1 are respectively disposed on the lap joint surface 1 1 2a and the dowel 1 2b, the vertical portion 13 is stamped and formed, and then bent 90 degrees along its four corners, the two ends are overlapped to form a rectangular frame 1. Moreover, it will be understood by those skilled in the art that the two ends of the frame member 10 are joined together at the corners of the rectangular frame 1 except for the corners, or are joined together at the corners of the rectangular frame 1. , its efficacy is exactly the same. As shown in Figures 5, 6 and 7, based on the same thinking, it will be understood by those skilled in the art that the recess 1 1 a and the projection 1 lb on the fascia 1 1 of the frame member 10 may be Corresponding triangles, rectangles, semi-ellipses, double semi-circles or other suitable shapes (not shown). The above is only the preferred embodiment of the present invention, and is not limited to the scope of the present invention, that is, the equivalent changes and modifications made without departing from the scope of the patent application should remain within the scope of this creation. In summary, the frame structure of the display panel of the present invention, in addition to reducing the consumables to a minimum extent and relatively reducing the cost, is aligned by relatively reducing the thickness of the lap joint and the corresponding concave and convex shape. This makes it easy to assemble between the sides, the interface is seamless, the positioning is accurate and the flatness is good. It is indeed a novel, progressive and industrially useful creation.
