Description

Description
REINFORCEMENT PANEL FOR LCD AND MANUFACTURING
METHOD THEREOF
Technical Field
[1] The present invention relates, in general, to a reinforcement panel for a liquid crystal display (LCD) and a method of manufacturing the same, and more particularly, to a reinforcement panel for an LCD and a method of manufacturing the same, in which torsion, bending rigidity, and impact-resistant strength can be improved significantly while minimizing the thickness of the reinforcement panel and a material thickness, in line with a trend toward the slimness of an LCD, i.e., a display means for various electronic products. Background Art
[2] In general, an LCD 1, i.e., one of display means for various electronic products has a reinforcement panel 2, as illustrated in FIG. 1, coupled to its rear portion.
[3] The reinforcement panel 2 is fabricated through blanking, piercing and bending processes. Corner portions 4 formed by a bending process of lateral portions 3 have opening portions. After the corner portions 4 are assembled with the LCD 1, torsion rigidity and impact-resistant strength are weakened due to a small assembly contact area at the time of assembly with counterpart assembly components and a weak structure of the opening portions. Accordingly, there has been an urgent need for the development of a reinforcement panel capable of solving a high defective proportion of a product.
[4] To solve the problems, the applicant of the present invention has early filed a Korean
Patent Application (Application No. 10-2004-15527) entitled "Reinforcement panel for LCD and method of manufacturing the same".
[5] That is, in the above patent application, as illustrated in FIG. 2, a reinforcement panel
10 for an LCD is fabricated, wherein corner portions 11 and lateral portions 12 constituting the reinforcement panel 10 are integrally formed by means of a deep drawing process. Accordingly, a manufacturing process can be very simplified and the impact- resistant property of the reinforcement panel 10 can be maximized to rigidly protect the LCD 13 from shock. Further, a product can be fabricated at low cost and there is an advantage in terms of price competitiveness.
[6] However, in recent years, as the development speed of a technique abruptly changes, the reinforcement panel for an LCD has a gradually thin thickness h according to a design structure of a slimmed LCD. Further, the thickness of a material tends to be thin in order to cope with deepened price competitiveness. [7] In other words, the thickness h of the past reinforcement panel was 2 to 3 mm, but becomes thin about 1.5 mm today. In the future, the thickness h of the past reinforcement panel will become 1.5 mm or less. The material thickness t accordingly must be changed from 0.2 to 0.3 mm to 0.15 mm. It is inevitable that the material thickness t of 0.15 mm or less be used in the future.
[8] As the thickness h of the reinforcement panel and the material thickness t become thin as described above, it becomes difficult to secure the reliability of a product. Therefore, there is a need for a manufacturing method capable of improving torsion force and impact-resistant strength of a reinforcement panel. Disclosure of Invention Technical Problem
[9] Accordingly, the present invention has been made in an effort to solve the above problems occurring in the prior art, and an object of the present invention is to provide a reinforcement panel for an LCD having a new construction, and a method of manufacturing the same, which can comply with a trend in which the thickness h of the reinforcement panel for an LCD and a material thickness t gradually become thin. Technical Solution
[10] To achieve the above objects, the present invention provides a reinforcement panel for an LCD and a method of manufacturing the same, in which the reinforcement panel for an LCD is fabricated by a deep drawing process, so that corner portions are integrally formed without opening portion, and lateral portions are then formed in plural stages by means of a multi-step bending or curling method, thus securing slimness and reliability of a product, and doubling torsion and impact-resistant strength.
Advantageous Effects
[11] As described above, in accordance with a reinforcement panel 10 for an LCD and a method of manufacturing the same according to the present invention, the reinforcement panel 10 for an LCD is formed so that corner portions 11 and lateral portions 12 are integrally formed by means of a deep drawing process. The inside and outside of the lateral portion 12 are selected and a reinforcement unit 12a is formed by means of one or more bending, curling methods or the like. Accordingly, the impact- resistant property, and bending and torsion rigidity of the reinforcement panel 10 can be maximized while very simplifying the manufacturing process. In particular, the reinforcement panel 10 can become slim in line with the slimness of an LCD, and there is a significant advantage in terms of price competitiveness. Brief Description of the Drawings
[12] FIG. 1 is a perspective view of a reinforcement panel for an LCD; [13] FIG. 2 is a perspective view of a reinforcement panel for an LCD, which was previously applied by the applicant of the present invention;
[14] FIG. 3 is a perspective view of a reinforcement panel according to an embodiment of the present invention;
[15] FIGS. 4 and 5 are cross-sectional views of the reinforcement panel according to an embodiment of the present invention;
[16] FIGS. 6 and 7 are cross-sectional views of the reinforcement panel according to another embodiment of the present invention; and
[17] FIG. 8 is a cross-sectional view of the reinforcement panel showing according to still another embodiment of the present invention. Mode for the Invention
[18] FIG. 3 is a schematic perspective view illustrating an embodiment of a reinforcement panel 10 for an LCD according to the present invention. FIGS. 4 and 5 are cross- sectional views of the reinforcement panel 10 shown in FIG. 3. FIGS. 6 and 7 are cross-sectional views of a reinforcement panel 10 according to another embodiment. The present invention will now be described in detail with reference to the accompanying drawings. In describing the present invention, the same reference numerals will be used to refer to the same parts as those of the prior art.
[19] In other words, in the reinforcement panel 10 for an LCD according to the present invention, as illustrated in the drawings, the corner portions 11 are integrally formed with the lateral portions 12, respectively, by means of a deep drawing process in the main body of the reinforcement panel 10. The lateral portion 12 includes a reinforcement unit 12a that is bent outwardly or inwardly through one or more bending steps.
[20] The reinforcement unit 12a can be also formed by means of a bending or curling process. Preferably, the reinforcement unit 12a can be formed outwardly as illustrated in FIGS. 4 and 5, or can be formed inwardly as illustrated in FIGS. 6 and 7. It has been shown in the drawings that the reinforcement unit 12a is formed by bending the lateral portions 12 through one step to two steps, but can be formed by bending the lateral portions 12 through three or five steps.
[21] FIG. 8 illustrates a case where the reinforcement unit 12a is formed outside the lateral portions 12 by means of a curling process.
[22] Experiments performed by the applicant of the present invention showed that the reinforcement panel 10 of the present invention, which has been fabricated by means of the deep drawing process and the bending or curling process, has very improved withstanding strength, impact-resistant property and so on compared with the existing reinforcement panel. Due to this, in selecting materials, cheaper material than that of the existing reinforcement panel can be used, and the cost price can be saved significantly.
[23] In the drawings, reference numeral 13 indicates the LCD.
[24] In the reinforcement panel 10 for an LCD that can be constructed above according to the present invention, after the corner portions 11 and the lateral portions 12 are integrally formed by means of the deep drawing process, the lateral portions 12 are selectively bent outwardly or inwardly, forming the reinforcement unit 12a through one or more steps of the bending or curling process. Therefore, the reinforcement panel 10 can be positively prevented from being twisted or bent due to various external force or impact. Accordingly, since torsion and bending of the reinforcement panel 10 can be prevented, the reinforcement panel 10 having a good strength can be provided, and a slim type reinforcement panel that complies with the slimness of the LCD 13, can be prevented.
[25] That is, the lateral portions 12 are formed selectively inwardly or outwardly to form the reinforcement unit 12a that is bent or curled one or more steps while minimizing the material thickness t of the reinforcement panel 10. It is therefore possible to further reduce the thickness h of the reinforcement panel 10, improve withstanding strength, bending rigidity, etc. of the reinforcement panel 10, and secure the reliability of a product.
[26] The impact-resistant property of the reinforcement panel 10 is significantly improved in order to prevent dropping or external shock due to a user's carelessness while using the LCD 13 for various electronic products protected by the reinforcement panel 10. It is thus possible to prevent damage to the LCD 13 and minimize a defective proportion. Industrial Applicability
[27] As described above, in accordance with a reinforcement panel 10 for an LCD and a method of manufacturing the same according to the present invention, the reinforcement panel 10 for an LCD is formed so that corner portions 11 and lateral portions 12 are integrally formed by means of a deep drawing process. The inside and outside of the lateral portion 12 are selected and a reinforcement unit 12a is formed by means of one or more bending, curling methods or the like. Accordingly, the impact- resistant property, and bending and torsion rigidity of the reinforcement panel 10 can be maximized while very simplifying the manufacturing process. In particular, the reinforcement panel 10 can become slim in line with the slimness of an LCD, and there is a significant advantage in terms of price competitiveness.
[28] Although the specific embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
