Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device having a lead fixing groove for fixing a lamp lead to a mold frame And when carrying and assembling the liquid crystal display device, the lamp lead is prevented from swinging freely to avoid damaging a soldering portion and avoiding a short circuit of the lamp lead. 2. Description of Related Art Recently, information processing devices are being developed to have a variety of shapes and functions and to process information more quickly. Since display devices are not lacking in information processing devices, display devices have also been improved to cope with the development of information processing devices. CRT (Cathode Ray Tube) monitors have been mainly used as display devices for various information processing devices, but recently, with the popularization of portable devices, liquid crystal display (hereinafter referred to as LCD) devices have been developed which are small and space-saving. Widely used as a display device for computers of commonly used information processing devices, home televisions suspended from walls, and other information processing devices. In general, an LCD device changes a specific molecular configuration of a liquid crystal layer into another specific molecular configuration by applying a voltage to the liquid crystal layer, and opticals such as brightness, optical linearity, dichroism, light scattering characteristics, and the like. The change in nature translates into a change in visual nature. In other words, the Lcd display device uses the light modulation of the liquid crystal cell (1 iqUid crystal cel 1) to display information. Since the LCD device is a passive display device that does not generate light by itself, a light source element such as a lamp is required to generate light on the back side of the LCD panel. Therefore, the lamp will consume 70% or more of the driving power of the LCD device. And 1300871

V. INSTRUCTION DESCRIPTION (2) Further, the LCD device includes a light guiding element (LGP) for guiding the light generated by the light source element to one of the LCD panels displaying an image. In a conventional LCD device, the light source element has one or more lamps, and the light guiding member assumes a plate shape having a desired thickness. The backlight assembly is housed in a container called a formwork that includes a lamp, a light guide, and other complementary components for generating and directing light to form a formwork assembly. Subsequently, the LCD panel was fixed to the formwork assembly by a module assembly method to make a device. Since the light source component consumes a large driving power in the LCD device, and the physical properties (such as shape, material, and the like) of the LGP have a large correlation with the brightness and size of the LCD panel, the structure of the backlight assembly is made in accordance with the structure of the backlight assembly. The external dimensions and light efficiency of the LCD device become different. Therefore, the mechanical and optical properties of the LCD device are greatly affected by the structure of the backlight assembly. Figure 1 shows a perspective view of one of the back surfaces of a conventional formwork assembly. Referring to Fig. 1, a mold frame assembly 90 includes a backlight assembly and a mold frame 1 including a backlight assembly. The backlight assembly includes a light unit (not shown) and a light guide unit (not shown) for generating light, and the light guide unit is configured to guide the generated light to one of the images for displaying LCD panel (not shown). The lamp unit includes a lamp that generates light (not shown); a lamp reflector (not shown) that surrounds the lamp and reflects light radiated from the lamp to the light guide unit to improve light efficiency; an inverter ( Not shown), which supplies a modified alternating muscle current to the lamp; and a plurality of lamp leads 22 that electrically connect the inverter to the lamp. The end of the lamp lead 22 is soldered to the lamp to secure the lamp lead 22, 1300871. V. Description of the Invention (3) A connector is attached to the other end of the lamp lead 22 to easily and safely connect the lamp lead 22 to the inverter. . The formwork 10 has a rectangular parallelepiped box shape with an upper opening, so that the formwork 10 has four side walls and one bottom. A floor portion 12 is formed on the bottom outer surface to support and fix the vertically curved printed circuit board on a latitudinal side surface of the formwork. A joint portion 14 is formed on a portion of the longitudinal side surface which is perpendicular to the side surface in the latitudinal direction to join a base to the mold base. A base (not shown) is combined with the mold base to bend the printed circuit board along the latitudinal side surface and fix the printed circuit board to the support portion 丨2. Also, a lead entry 16 is formed in the vicinity of the joint portion 14 to allow a lamp lead that connects a power source (not shown) outside the mold frame to the lamp in the mold frame. The light guiding unit comprises: a light guiding plate (hereinafter referred to as LGp) for guiding the light generated by the lamp to the LCD panel; and a reflecting plate mounted on the lower side of the LGp to reflect the leakage light of the LGP to the LCD panel And an optical sheet for enhancing the light concentration efficiency toward the LCD panel. With the above elements, the light guiding unit can convert a linear light source generated by a lamp unit located on one side edge portion of the LCD panel into a planar light source for the LCD panel. The lamp unit is placed on an inner side of the formwork 10 and the light guide unit is placed on an opposite side of the lamp unit in the formwork 10 to assemble the formwork assembly 9''. After assembly, the formwork assembly 9 is transported in a modular assembly process. In the module assembly method, an LCD panel for displaying an image is mounted on an upper portion of the mold frame assembly 90, and a base for fixing the LCD panel to the mold frame is assembled with the joint portion 14 A liquid crystal display device is fabricated. At this time, a lamp lead 22 is taken from the lead inlet 16 and connected to an inverter (not shown) to supply electric power 1300871 V, invention description (4) to the lamp. When the connector 24 is connected to a transducer (not shown) to operate the liquid crystal display device, electric power of an alternating current is supplied to the lamp via the lamp lead 22, thereby generating light from the lamp. Subsequently, the light guide unit directs the light to the lCD board and displays an image on the LCD panel. Therefore, the lamp lead 22 of the liquid crystal display device should always be exposed outside the mold frame 1 to supply a current for driving the backlight assembly from an external power source. However, since the lamp lead 22 is exposed, it causes a connection failure and the work of fixing the lamp lead 22 twice when manufacturing the liquid crystal display device. Because the lamp lead 22 is directly exposed to the mold frame 1 during the transfer method of the formwork assembly 90 or during the module assembly method, an unexpected pulling force may be applied when the lamp lead 22 is entangled or jammed. To the lamp lead 22, an unexpected pulling force will cause the weld on the connector 24 to break, and thus a connection failure may occur. Therefore, the power cannot be applied to the lamp due to the connection failure of the lamp lead. In order to prevent the lamp lead 22 from being entangled or stuck, the mold lead assembly 90 is transferred into the module assembly in the case where the lamp lead 22 is temporarily fixed to the rear surface of the formwork assembly 9 by an adhesive such as adhesive tape. In the method. In the module assembly method, the adhesive is removed and the formwork assembly is assembled 9 turns. After the assembly method is completed, the lamp leads are again fixed to the rear surface of the mold frame with adhesive tape. Then, the LCD device is loaded into the protective tape and transported. Therefore, the transfer step of the formwork assembly and the transfer step of the LCD device are repeated twice for an adhesive, which increases the material cost and processing time of the device for manufacturing the Lcj). 7 1300871 V. INSTRUCTIONS (5) SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the related art. Therefore, it is an object of the present invention to provide a liquid crystal display device in which a lamp lead is fixed to one side surface of a mold frame. The fixing and separation of the lamp leads can be easily and simply performed. In order to achieve the object of the present invention, a liquid crystal display device comprising: a liquid crystal display panel displaying an image; a backlight assembly having a light supply component and a lamp lead, the light supply component comprising A light source for generating light, the lamp lead for supplying light to the light supply member, and a mold frame for housing the backlight assembly and the liquid crystal display panel and having a fixing means for fixing the lamp lead. The fixing device is a fixing groove formed by cutting off the side surface portion or excavating the rear surface portion of the mold frame, thereby constituting a space in which the lamp lead is housed. A pair of fixing ribs are formed on the bottom of the fixing recesses facing each other, and the lamp leads are fixed in a space between the fixing ribs having a smaller width than the lamp lead. According to an embodiment of the present invention, the fixing and separation of the lamp leads can be easily and simply performed by fixing the lamp leads to the side surface of the mold frame. Therefore, the connection failure of the welded portion due to the sway of the lamp lead can be prevented, and it is no longer necessary to fix the lamp lead cumbersomely when manufacturing the liquid crystal display device. Therefore, the material cost can be reduced and the processing time can be reduced.

Since the lamp 3 10 radiates light in all directions, the light emitted in a direction opposite to the LGP is by the lamp reflector. 312 is reflected toward the LGP to enhance light efficiency. The LGP320 is made of a transparent material such as a acryl resin and has a plate shape including a slanted rear surface and a flat front surface opposite to the slanted rear surface. In another embodiment of the invention, the LGP may be formed such that the rear surface is flat and the front surface is inclined. The LGP 320 is located under the LCD panel 200, and after the light is guided through the side surface of the LGP 320 near the lamp 310, the lamp 31 is generated. The light is incident on the LCD panel 200 via the front surface. The reflector 340 is located under the LGP320 and the optical sheet 330 is positioned above the LGP320 to improve light concentration efficiency. The reflector 340 can transmit light. The reflection is again reduced toward the front surface of the LGP320, which is caused by leakage from the rear surface of the LGP320 that is not incident on the LCD panel 200. The optical sheet 330 is disposed between the LGP 320 and the LCD panel 200 to enhance the emission of the LGP320. And uniformly inputting the light concentration efficiency of the light of the LCD panel 200. Although not shown, another embodiment of the backlight assembly may be provided, wherein one light source such as one or more lamps is directly disposed on the LCD panel. There is no LGP underneath, which is referred to as a direct type backlight assembly. And in the process, the scope of the present invention includes this direct type backlight assembly. The mold frame 400 supports and houses the LCD panel 200 and the backlight assembly 300'. The mold base 11 1300871 5. The invention description (9) 400 presents a box shape and the upper portion of the mold frame is opened. That is, the mold frame has four side walls and a portion of the source printed circuit board 22 and the closed printed circuit board 230 are bent on the outer surface of the mold frame. One of the bent portions for supporting and fixing the bent portions of the source printed circuit board 220 and the gate printed circuit board 23 () is formed on the rear surface of the mold frame 400. A lead inlet 410 is formed on one end of one side surface of the mold frame 4 to expose the lamp lead to the outside of the mold frame 400. Further, a first base coupling portion 420a and a second base coupling portion 42b are formed on both ends of the side surface of the mold frame 4, and a lead entry 41A is formed therein. In a preferred embodiment of the invention, one side of the formwork 400 between the first base coupling portion 42 and the second base coupling portion 420b is removed to brighten the LCD device. A partition wall 430 is located near the lead inlet 410 to separate the lead entry 41'' from the first base engaging portion 420b. That is, the partition 430 is a portion of the side of the mold frame 4 that is located between the lead inlet 41 〇 and the first base fitting portion 420b having a desired thickness. In the fixing member of the first embodiment of the present invention, a first fixing groove 432 is formed on a portion of the partition 430 to fix the lamp lead. The first fixing groove 432 is formed to be slightly smaller than the diameter of the lamp lead, so that the lamp lead is forcibly inserted and firmly fixed into the fixing groove. Further, the fixing of the fixing member such as a fixing projection, an adhesive tape, a fixing clip, and the like can be used to further securely fix the lamp lead, thereby preventing the sway of the lamp lead. In addition, although the expected external stress is applied to the lamp lead when the lamp lead is entangled or stuck, the resistance against tensile stress is generated on the surface of the fixing groove. Therefore, the lamp 310 can be prevented from being disconnected from the lamp lead 314. 12 1300871 V. Inventive Description (10) The base 500 has a rectangular parallelepiped similar to one of the mold frames 400. In other words, an upper portion of the base 500 is open to expose the LCD panel 200, and one side of the base 500 is oriented. The mold base 400 is bent vertically to cover a peripheral portion of the upper surface of the LCD panel 200. Therefore, the base 500 can bend and fix the source printed circuit board 220 and the gate printed circuit board 230 along the outer surface of the mold frame 400 to the bottom of the mold frame 400. The backlight assembly 300 is housed in a mold base 400 to complete a formwork assembly. Subsequently, in a module assembling method, the LCD panel 200 is assembled on the upper surface of the mold frame assembly, and the base 500 is assembled to cover and fix the LCD panel 200 to the mold frame 400. A front case 600 and a rear case 700 are then assembled to form an LCD device. Subsequently, if a lamp lead and an inverter (not shown) for supplying an alternating current are connected via a connector, the lamp 310 generates light and supplies light to the LCD panel 200 via the LCD 320 to the LCD panel. An image is displayed on the 200. Fig. 3 is a perspective view showing a rear surface of the liquid crystal display device shown in Fig. 4. Fig. 4 is a cross-sectional view showing the first fixing groove taken along line A-A of Fig. 3. Referring to Figures 3 and 4, the lamp lead 314 is forcibly inserted into the first fixing groove formed at one end of the partition wall 430, thereby preventing the lamp lead 314 from swinging. At this time, the first fixing groove 432 has a sufficient depth "d" to accommodate the hot and cold leads of the lamp lead 314. Also, the width "w" of the first fixing groove 432 is smaller than the diameter of the lamp lead 314, so that the hot wire and the cold wire are forcibly inserted into the first fixing groove 432. The width "w" of the first fixing groove 432 is smaller than the diameter of the lamp lead 314 but not less than 80%, preferably 90%, of the diameter of the lamp lead 314. And, on the 13th 1300871

V. INSTRUCTION DESCRIPTION (11) In a fixing groove 432, a barrier wall (not shown) may be formed between the hot lead and the cold lead to electrically insulate the hot lead from the cold lead. The barrier wall can be used to improve the electrical stability of the lamp lead 314 by blocking electrical interaction between the hot and cold leads. Therefore, when an unexpected pulling force is applied to the lamp lead 314 due to entanglement or jamming of an obstacle, the pulling force on the surface of the lamp lead 314 of the fixing groove 432 is reversed to generate a frictional force against the pulling force. When a resistance is applied, the pulling force hardly affects the welded portion for connecting the lamp 31 to the lamp lead 314. Therefore, the connection failure of the welded portion of the lamp lead 314 is remarkably reduced. Although the side of the mold frame 4 between the first base coupling portion 420a and the second base coupling portion 420b is removed in accordance with the first embodiment of the present invention to brighten the LCD device, it is not necessary to remove the side portion in other embodiments. . In particular, in a large LCD device of a computer or a television, the side portion of the formwork 4 between the first base coupling portion 420a and the first base engaging portion 420b remains. In this case, the first fixing groove may be formed at a desired depth on a portion of one side surface of the mold frame. 5A, 5B, 5C are cross-sectional views showing a first fixing groove having a fixed supplement according to another embodiment. The lamp lead 3 14 is more securely secured to the formwork 400 by a variety of fixed supplements. The fixing complement, such as the first side wall 432c and the second side wall 432d of the fixing groove 432 shown in FIG. 5A, is fixed. A piece 434, one of the adhesive tapes 436 and a fixing clip 438, as shown in Figures 5B and 5C, respectively. Referring to FIG. 5A, the fixing protrusions 434 including a first protrusion 434a and a second protrusion 434b are alternately formed on the first and second sides 1300871 facing each other. 5. The side wall of the invention (l2) Therefore, the fixing protrusion portion 434 can prevent the lamp lead 314 from being separated from the fixing groove 432. That is, the first protrusion 434a protrudes from the first side wall inside the first fixing groove 432, and the second protrusion 434b protrudes from the second side wall 432d outside the fixing groove 432. To this end, the first protrusion 434a and the second protrusion 434b are alternately formed in the first fixing groove 432. In an embodiment of the fixing protrusion 434, the first protrusion 434a and the second protrusion 434b may exhibit an alternating configuration on the same sectional plane including the first protrusion 434a and the second protrusion 434b (rather than the same Meet on the vertical line). During the process, the first protrusion 434a and the second protrusion 434b are interchangeable, that is, the first protrusion 434a may be located near the opening of the fixing groove 432, and the second protrusion 434b may be located near the bottom of the fixing groove 432. The fixing projection portion 434 can be of any shape, but is preferably cylindrical in view of the manufacturing equipment. The fixing protrusion portion 434 prevents the lamp lead 3 14 inserted into the fixing groove 432 from coming off the fixing groove 432, thereby surely fixing the lamp lead 314 to the fixing groove 432. Referring to Fig. 5B, an adhesive tape 436 is provided to cover the opening of the fixing groove 432 and includes the lamp lead 314. The adhesive tape 436 is adhered to the entire one side surface of the partition wall 430. Referring to FIG. 5C, a fixing clip 438 is provided to cover the opening portion of the fixing groove 432 and includes a lamp lead 314. The fixing clip 438 is made of an elastic material which has excellent restoring force (or elastic force) and is restored by force. Adhered to an upper and lower surface of the partition 430. The fixing clip 438 prevents the lamp lead 3 14 inserted into the fixing groove 432 from coming off the fixing groove 432, thereby surely fixing the lamp lead 314 to the fixing groove 432. With the fixed supplement described above, the lamp leads that provide current to the backlighted lamp are tightly and securely secured to the formwork. Therefore, it can be reduced because the lamp base 15 1300871 17 describes the same baseline C! and the right triangle height C2, the truncated angle is about 45 degrees. The structure of the truncated surface 448 and a method of forming the truncated surface 448 are equally applicable to the other angled surface formed on the upper edge of the latitudinal side wall 44〇c of the second fixing groove 440. Embodiment 3 Fig. 10 is a perspective view showing a rear surface of a mold base assembly having a fixing member according to a third embodiment of the present invention. Referring to Fig. 10, a fixed illuminating 450 series garment for fixing the lamp lead 314 to one side surface of the partition 430 and fixing the lamp lead 314 to the outer surface of the partition 430. When the lamp lead 314 is fixed to the partition wall 43, it is compressed between the outer surface of the partition 430 and an inner surface of the fixing clip 45, and then a frictional force generated on the surface of the lamp lead 314 can prevent the lamp lead 3 from being formed. 14 produces a swing. To this end, the lamp lead 3 14 can be fixed to the formwork 400 without additionally modifying the partition 430. Figure 11 shows a fixed member of the lamp taken along line C-C of Figure 10. As shown in Fig. 11, the retaining clip 450 forms a rectangular parallelepiped in which a side surface, a top surface and a bottom surface are opened to include a body portion, a first extension portion and a second extension portion. The lamp lead 314 is compressed between the one side surface 430a of the partition 430 and the body of the fixed clip 450 by the restoring force of the fixing clip 450. In another embodiment of the retaining clip 450, the retaining clip 450 can further include a distinct portion on an inner surface of the first extension and the second extension to enhance engagement of the retaining clip 450 with the partition 430. 20 1300871 V. INSTRUCTIONS (u) Figure 12 shows a pattern of an adhesive tape that replaces the retaining clip of the second drawing.

Referring to Fig. 12, an adhesive tape 46 is adhered to the side surface 430a of the partition 430 to fix the lamp lead 314. A hot lead and a cold lead are separated from each other by a sufficient distance such that an adhesive surface between the adhesive tape 460 and the outer surface 430a has a widest possible fixed distance to avoid current leakage due to contact of the hot lead with the cold lead. Also, the adhesive tape 460 may extend to the upper surface 430b and the bottom surface 430c of the partition 430. Therefore, it is possible to reduce the connection failure of the solder portion due to the sway of the lamp lead and to eliminate the method of reattaching the lamp lead 22 when manufacturing the liquid crystal display device. And the 'trunched surface prevents damage to the lamp lead due to friction between the fixing rib and one edge line of the fixed recess. According to the present invention, a fixing portion or a member for fixing and separating the lamp lead easily and simply by fixing the lamp lead to the mold frame can reduce the cause

Swinging the lamp lead causes the soldering portion of the lamp lead to cause connection defects and prevent entanglement of the lamp lead. Moreover, it is no longer necessary to repeatedly perform the attachment of the adhesive in the moving step of the formwork assembly and in the transporting step of the lcd device. Having described the invention in detail, it is understood that various modifications, changes and changes may be made without departing from the spirit and scope of the invention. 〃 21 1300871 V.
