## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a backlight assembly and an LCD (Liquid Crystal Display) apparatus, and more particularly to a backlight assembly assembled with multiple parts separable from each other to easily replace components thereof and an LCD apparatus having the same.
2. Description of the Related Art
Information-processing devices have been rapidly developed to provide and facilitate various architectures, functions and information processing speed. Information is processed in such an information-processing device in the form of electrical signals. Thus, to visually display the information processed in an information-processing device, a display device is necessary to serve as an interface means between electrical signals and images to be displayed on the display device.
There have been developments in liquid crystal display devices, which are generally lighter and smaller than CRT type display devices. The liquid crystal display devices have been developed to have advanced functions such as full color and high resolution. As a result, the liquid crystal display devices are widely used for computer monitors, television sets, etc.
FIG. 1 is an exploded perspective view showing a structure of a conventional LCD apparatus.
Referring to FIG. 1, an LCD apparatus 40 includes a mold frame 10, a first lamp unit 16 and a second lamp unit 18 for generating light, a first lamp cover 12 and a second lamp cover 14 for reflecting the light from the first and second lamp units 16 and 18, a light guide plate 22 for guiding the light, a reflecting plate 20 for reflecting the light leaked from the light guide plate 22, one or more optical sheets 26 for controlling brightness of the light emitted from the light guide plate 22, a display unit 28 for displaying images in response to the light supplied from the optical sheet 26, and a top chassis 30 for fixing the display unit 28 to the mold frame 10.
The mold frame 10 provides a space for receiving the above-mentioned components. The first and second lamp units 16 and 18 are received at two end portions, respectively, of the receiving space. Each of the first and second lamp units 16 and 18 has a plurality of lamps. The first and second lamp units 16 and 18 are covered by the first and second lamp covers 12 and 14 to reflect light from the first and second lamp units 16 and 18, respectively. The reflecting plate 20, light guide plate 22, optical sheets 26 and display unit 28 are sequentially received in the receiving space of the mold frame 10. The top chassis 30 has a bottom surface, which is open to expose an effective display area of the display unit 28. The top chassis 30 is combined to the mold frame 10 to fix the display unit 28 to the mold frame 10.
In the LCD apparatus 40, the amount of light needed to display an image on the display unit 28 increases according as a size of the display unit 28 becomes larger. That is, in order to uniformly maintain the brightness distribution of the light supplied from the first and second lamp units 16 and 18 to the display unit 28 through the light guide plate, the amount of the light has to be increased in proportion to the increase of the size of the display unit 28. Accordingly, the conventional LCD apparatus 40 employs a plurality of lamps as shown in FIG. 1.
However, when the number of lamps of the first and second lamp units 16 and 18 increases so as to obtain the amount of the light appropriate to display images, a thickness of the LCD apparatus 40 becomes thicker.
Further, since the multiple lamps are disposed adjacent to the opposite side surfaces of the light guide plate 22, the heat emitted from the multiple lamps is concentrated on the side surfaces. As a result, circuit parts of the display unit 28 adjacent to the first and second lamp units 16 and 18 may be damaged.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 is an exploded perspective view showing an LCD apparatus according to an embodiment of the present invention. FIG. 3 is a cross-sectional view showing a structure of the LCD apparatus shown in FIG. 2.
Referring to FIGS. 2, and 3, an LCD apparatus 500 includes a display unit 100 for receiving image information and displaying images and a backlight assembly 200 for supplying light to the display unit 100.
The display unit 100 includes an LCD panel 110, a data PCB (Printed Circuit Board) 120, a gate PCB 130, a data TCP (Tape Carrier Package) 140 and a gate TCP 150. The LCD panel 110 includes a TFT (Thin Film Transistor) substrate 113, a color filter substrate 111 and liquid crystal (not shown).
The TFT substrate 113 is a transparent glass substrate on which TFTs (not shown) are disposed in a matrix configuration. Each of the TFTs includes a source terminal connected to a data line, a gate terminal connected to a gate line and a drain terminal having a pixel electrode made of ITO (Indium Tin Oxide), which is transparent conductive material. When an electric signal is applied to the data and gate lines, the source and gate terminals of each of the TFTs receive the electric signal through the data and gate lines. Responding to the electric signal, the TFTs are turned on or turned off, so that the drain terminal receives the electric signal needed to control a pixel.
The color filter substrate 111 is disposed facing the TFT substrate 113. RGB pixels, which are color pixels for emitting predetermined colors when the light passes therethrough, are formed on the color filter substrate 111 through a thin film process. A common electrode made of ITO is disposed on the entire surface of the color filter substrate 111.
When a power is applied to the gate and source terminals of selected TFTs disposed on the TFT substrate 113, the selected TFTs are turned on so that an electric field is formed between the pixel electrodes of the selected TFTs and the common electrode of the color filter substrate 111. The electric field varies an aligning angle of the liquid crystal interposed between the TFT substrate 113 and the color filter substrate 111. Accordingly, light transmittance of the liquid crystal varies according to the variation of the aligning angle of the liquid crystal, so that desired images may be obtained on the display unit 100.
As shown in FIG. 2, the data TCP 140 is connected to the data line of the LCD panel 110 to control the timing of a data driving signal, and the gate TCP 150 is connected to the gate line of the LCD panel 110 to control the timing of a gate driving signal. The data PCB 120 for receiving an image signal externally provided and applying the data driving signal to the data line is connected to the data TCP 140, and the gate PCB 130 for applying the gate driving signal to the gate line is connected to the gate TCP 150.
Although it is shown in FIG. 2 that the data PCB 120 is separately disposed from the gate PCB 130 in the LCD apparatus 500, the data PCB and the gate PCB may be disposed in the LCD apparatus 500 as an integrated PCB (not shown).
The backlight assembly 200 includes a first lamp unit 210 and a second lamp unit 220 for generating the light, a light guide plate 230 for guiding the light to the display unit 100, one or more optical sheets 240 for controlling a visual angle of the light from the light guide plate 230, and a reflecting plate 245 for reflecting the light leaked from the light guide plate 230. The optical sheets 240 are disposed on the light guide plate 230, and the reflecting plate 245 is disposed under the light guide plate 230. The light guide plate 230, first lamp unit 210, second lamp unit 220, optical sheets 240 and reflecting plate 245 are received in a mold frame 280.
The mold frame 280 is received in a bottom chassis 400 with the light guide plate 230, first lamp unit 210, second lamp unit 220, optical sheets 240 and reflecting plate 245. The display unit 100 is disposed on the optical sheets 240 and fixed to the bottom chassis 400 by combining a top chassis 300 to the bottom chassis 400.
FIG. 4 is a perspective view showing a combination structure of the backlight assembly shown in FIG. 2. FIG. 5 is a cross-sectional view taken along the line II-II′ of the combination structure of the backlight assembly shown in FIG. 4. FIG. 6 is a cross-sectional view taken along the line III-III′ of the combination structure of the backlight assembly shown in FIG. 4.
Referring to FIGS. 4 to 6, the light guide plate 230 includes first to fourth side surfaces 231, 232, 233 and 234 for receiving the light, an emitting surface 235 for emitting the light, and a reflecting surface 236 for reflecting the light to the emitting surface 235. The light guide plate 230 guides the light to the LCD panel 110, which is input through the first to fourth side surfaces 231, 232, 233 and 234.
The first lamp unit 210 includes a first L-shaped lamp 211 having a first light generating portion G1 and a second light generating portion G2 integrally formed with the first generating portion G1, and a first lamp reflector 213 for covering the first L-shaped lamp 211. The second lamp unit 220 includes a second L-shaped lamp 221 having a third light generating portion G3 and a fourth light generating portion G4 integrally formed with the third generating portion G3, and a second lamp reflector 223 for covering the second L-shaped lamp 221.
As shown in FIGS. 5 and 6, the first and second light generating portions G1 and G2 of the first L-shaped lamp 211 are disposed adjacent to the first and second side surfaces 231 and 232 of the light guide plate 230, respectively. The third and fourth light generating portions G3 and G4 of the second L-shaped lamp 221 are disposed adjacent to the third and fourth side surfaces 233 and 234 of the light guide plate 230, respectively.
The first lamp reflector 213 has an L shape for covering the first and second light generating portions G1 and G2. The first lamp reflector 213 has a first end portion open to expose a first end portion of the first L-shaped lamp 211 and a second end portion not open to cover a second end portion opposite to the first end portion of the first L-shaped lamp 211. The first lamp reflector 213 reflects the light from the first L-shaped lamp 211 to the light guide plate 230. Similarly, the second lamp reflector 223 has an L shape for covering the third and fourth light generating portions G3 and G4. The second lamp reflector 223 has a first end portion open to expose a first end portion of the second L-shaped lamp 221 and a second end portion not open to cover a second end portion opposite to the first end portion of the second L-shaped lamp 221. The second lamp reflector 223 reflects the light from the second L-shaped lamp 221 to the light guide plate 230. The first and second lamp reflectors 213 and 223 are fixed to the mold frame 280, for example, by adhesive material such as adhesive tape.
Referring to FIGS. 5 and 6, the mold frame 280 includes a bottom surface 285, first to fourth sidewalls 281, 282, 283 and 284 extended from the bottom surface 285 so as to provide a receiving space, and first to fourth upper surfaces 286, 287, 288 and 289 extended from the first to fourth sidewalls 281, 282, 283 and 284, respectively. The first to fourth upper surfaces 286, 287, 288 and 289 are extended in parallel to the bottom surface 285. The light guide plate 230 is received in the receiving space, so that the first to fourth side surfaces 231, 232, 233 and 234 face the first to fourth sidewalls 286, 287, 288 and 289, respectively.
The first light generating portion G1 is disposed between the first side surface 231 and the first sidewall 281, and the second light generating portion G2 is disposed between the second side surface 232 and the second sidewall 282. The third light generating portion G3 is disposed between the third side surface 233 and the third sidewall 283, and the fourth light generating portion G4 is disposed between the fourth side surface 234 and the fourth sidewall 284. The optical sheets 240 are disposed on the light guide plate 230.
FIG. 7 is an exploded, perspective view of the first and second lamp units shown in FIG. 4.
Referring to FIG. 7, the first sidewall 281 may be separated from the second and third sidewalls 282 and 283, and the first upper surface 286 integrally formed with the first sidewall 281 may be separated from the second and third upper surfaces 287 and 288. The first bottom surface 285a integrally formed with the first sidewall 281 and corresponding to the first upper surface 286 may be separated from a third bottom surface 285c. Hereinafter, the first sidewall 281, first upper surface 286 and first bottom surface 285a are referred to as a “first mold part 260”.
The third sidewall 283 may be separated from the first and fourth sidewalls 281 and 284, and the third upper surface 288 integrally formed with the third sidewall 283 may be separated from the first and fourth upper surfaces 286 and 289. A second bottom surface 285b integrally formed with the third sidewall 283 and corresponding to the third upper surface 288 may be separated from the third bottom surface 285c. Hereinafter, the third sidewall 283, third upper surface 288 and second bottom surface 285b are referred to as a “second mold part 270”. The remaining part of the mold frame, except for the first and second mold parts 260 and 270, is referred to as a “third mold part 250”. The third mold part 250 includes the second sidewall 282, the fourth sidewall 284 connected to the second sidewall 282, the second and fourth upper surfaces 287 and 289 respectively extended from the second and fourth sidewalls 282 and 284, and the third bottom surface 285c. 
When the first mold part 260 is separated from the third mold part 250, the first lamp unit 210 is withdrawn along with the first mold part 260 from the third mold part 250. When the second mold part 270 is separated from the third mold part 250, the second lamp unit 220 is withdrawn along with the second mold part 270 from the third mold part 250.
This is because the first lamp reflector 213 is adhered to the first mold part 260, for example, by adhesive and not adhered to the third mold part 250. Thus, the first lamp unit 210 may be separated from the third mold part 250 when the first mold part 260 is separated from the second and third mold parts 270 and 250. Further, since the second lamp reflector 223 is adhered to the second mold part 270 and not adhered to the third mold part 250, the second lamp unit 220 may be separated from the third mold part 250 when the second mold part 270 is separated from the first and third mold parts 260 and 250.
Accordingly, when the first and second L-shaped lamps 211 and 221 are damaged, the first and second L-shaped lamps 211 and 221 can be easily replaced without entirely disassembling the backlight assembly 200.
FIG. 7 shows an exemplary embodiment of the backlight assembly 200 having a structure of disassembling the first and second mold parts 260, 270 from the mold frame 280. It is difficult to withdraw the first and second lamp units 210 and 220 from the sides of the second and fourth sidewalls 282 and 284 in case that the data and gate PCBs 120 and 130 are bent to a rear surface of the mold frame 280 while covering the second and fourth sidewalls 282 and 284 of the mold frame 280. Thus, in this case the first and second lamp units 210 and 220 are withdrawn from the sides of the first and third sidewalls 281 and 283 on which the data and gate PCBs 120 and 130 are not disposed.
However, assuming that the LCD apparatus 500 employs an integrated PCB (not shown), the first and second lamp units 210 and 220 may be withdrawn through three sides of the first to fourth sidewalls 281, 282, 283 and 284 of the mold frame 280 except only one sidewall on which the integrated PCB is disposed.
FIGS. 8 and 11 are perspective views showing the mold frame shown in FIG. 4. FIGS. 9 and 10 are partially enlarged views showing a combination structure of the mold frame shown in FIG. 8.
Referring to FIGS. 8 and 9, the mold frame 280 includes the first, second and third mold parts 260, 270 and 250. The third mold part 250 is provided with a first engaging hole 251a disposed on a first end portion 251 thereof which comes in contact with the first mold part 260 and provided with a second engaging hole 252a disposed on a second end portion 252 thereof which comes in contact with the second mold part 270. The first mold part 260 is provided with a first engaging protrusion 261a corresponding to the first engaging hole 251a and disposed on a third end portion thereof, and the second mold part 270 is provided with a second engaging protrusion (not shown) corresponding to the second engaging hole 252a and disposed on a fourth end portion 271 thereof.
Accordingly, the first mold part 260 is combined to the third mold part 250 by engaging the first engaging protrusion 261a into the first engaging hole 251a. The second mold part 270 is coupled to the third mold part 250 by engaging the second engaging protrusion into the second engaging hole 252a. 
As shown in FIG. 9, the first engaging protrusion 261a is formed such that a cross-sectional surface of the area integrally connected to the first mold part 260 has an areal size (e.g., diameter) smaller than that of a cross-sectional surface of the end portion of the first engaging protrusion 261a. The first engaging hole 251a has a shape matching with the first engaging protrusion 261a. When the first engaging protrusion 261a is engaged into the first engaging hole 251a, the first engaging hole 251a is momentarily expanded to receive the end portion of the first engaging protrusion 261a. To facilitate such expansion, the first mold part 260 may be made of plastic material. The first engaging hole 251a is returned to the initial state after completely receiving the first engaging protrusion 261a, so that the first engaging protrusion 261a may be fixed to the first engaging hole 251a. The second engaging protrusion may have a shape identical to that of the first engaging protrusion 261a. 
Referring to FIGS. 8 and 10, the first mold part 260 is provided with a third engaging hole 262a disposed on a fifth end portion 262 thereof which comes in contact with the second mold part 270. The second mold part 270 is provided with a third engaging protrusion 272a disposed on a sixth end portion 272 thereof which comes in contact with the first mold part 260. The third engaging protrusion 272a is engaged into the third engaging hole 262a. 
Accordingly, the second mold part 270 is combined to the first mold part 260 by engaging the third engaging protrusion 272a into the third engaging hole 262a. The third engaging protrusion 272a may have a shape identical to the first and second engaging protrusions.
By combining the first, second and third mold parts 260, 270 and 250, the mold frame 280 is formed as shown in FIG. 11. In FIGS. 8 to 10, the first, second and third mold parts 260, 270 and 250 may be combined to each other using other assembling parts such as screws or hinges.
FIG. 12 is a perspective view showing a structure of the first and second lamp units shown in FIG. 4.
Referring to FIG. 12, the first lamp unit 210 includes the first L-shaped lamp 211 and the first lamp reflector 213. The first L-shaped lamp 211 includes first and second electrodes (not shown) disposed at the end portions thereof, respectively. The first and second electrodes may be disposed on either inner or outer surface of the first L-shaped lamp 211.
The first lamp unit 210 includes a first power line 214 electrically connected to the first electrode and a second power line 215 electrically connected to the second electrode. The first power line 214 provides electrical connection between the first electrode and a first connector 219, and the second power line 215 provides electrical connection between the second electrode and the first connector 219. The first connector 219 is connected to a power supply device (not shown).
The power supply device supplies a high voltage to the first L-shaped lamp 211 through the first power line 214 and supplies a low voltage to the first L-shaped lamp 211 through the second power line 215. As shown in FIG. 12, the second power line 215 is extended from the second electrode toward the first electrode along the first L-shaped lamp 211 so that the first and second power lines 214, 215 are connected to the first connector 219. Thus, one power supply device is needed for the first and second power lines 214, 215 instead of preparing two power supply devices for the respective power lines, so that the entire size of the LCD apparatus 500 is reduced. It should be noted that the first power line 214 may be extended, as does the second power line 215, to accomplish the same purpose.
The first L-shaped lamp 211 includes a first lamp holder 216 for holding the first power line 214 and a second lamp holder 217 for holding the second power line 215. The first and second lamp holders 216 and 217 are inserted into the end portions of the first L-shaped lamp 211, respectively, and serve for preventing the first and second power lines 214 and 215 from being disconnected with the first and second electrodes. The first L-shaped lamp 211 is received in the first lamp reflector 213 having an L shape identical to that of the first L-shaped lamp 211. The first lamp reflector 213 includes a first reflecting surface 213a, a second reflecting surface 213b extended from a first end portion of the first reflecting surface 213a and perpendicular to the first reflecting surface 213a, and a third reflecting surface 213c extended from a second end portion of the first reflecting surface 213a and facing the second reflecting surface 213b, so that the first lamp reflector 213 reflects the light from the first L-shaped lamp 211 to the light guide plate 230. The second and third reflecting surfaces 213b and 213c are extended by a same length.
The first lamp reflector 213 may further include a receiving groove disposed on the outer surface thereof so as to receive the second power line 215 and a fixing member for fixing the second power line 213 thereto.
The second lamp unit 220 includes the second L-shaped lamp 221, a second lamp reflector 223, a third power line 224, a fourth power line 225, a third lamp holder 226, a fourth lamp holder 227 and a second connector 229. The second lamp unit 220 has the substantially same structure as that of the first lamp unit 210, so that a detailed description with respect to the same parts, such as the second L-shaped lamp 221, second lamp reflector 223, third and fourth power lines 224 and 225, third and fourth lamp holders 226 and 227 and second connector 229 will be omitted.
The first and second lamp units 210 and 220 are disposed in a rectangular frame shape. Thus, the first lamp holder 216 of the first L-shaped lamp 211 is disposed adjacent to the third lamp holder 226 of the second L-shaped lamp 221, and the second lamp holder 217 of the first L-shaped lamp 211 is disposed adjacent to the fourth lamp holder 217 of the second L-shaped lamp 221.
FIG. 13 is a perspective view showing first and second lamp reflectors according to another embodiment of the present invention.
Referring to FIG. 13, a first lamp reflector 218 includes a first reflecting surface 215, a second reflecting surface 216 vertically extended from a first side edge 215a of the first reflecting surface 215, and a third reflecting surface 217 vertically extended from a second side edge 215b of the first reflecting surface 215. The second reflecting surface 216 faces the third reflecting surface 217, and the first and second side edges 215a and 215b are opposite to each other. The third reflecting surface 217 is extended to the line connecting between a first end edge 215c and a second end edge 215d of the first reflecting surface 215.
A second lamp reflector 228 includes a fourth reflecting surface 225, a fifth reflecting surface 226 vertically extended from a third side edge 225a of the fourth reflecting surface 225, and a sixth reflecting surface 227 vertically extended from a fourth side edge 225b of the fourth reflecting surface 225. The fifth reflecting surface 226 faces the sixth reflecting surface 227, and the third and fourth side edges 225a and 225b are opposite to each other.

That is, the first and second mold parts 260 and 270 are separated from the top chassis 300 by disengaging the first and second engaging protrusions 286a and 288a of the first and second mold parts 260 and 270 from the first and second engaging holes 311 and 331 of the top chassis 300.
The first and second mold parts 260 and 270 may be separated from the third mold part without entirely removing the top chassis 300 because the top chassis 300 does not include sidewall portions corresponding to the first and second mold parts 260 and 270. Also, since the first and second mold parts 260 and 270 are combined to the top chassis 300 in a hook structure, the first and second mold parts 260 and 270 may be separated from the third mold part without entirely removing the top chassis 300.
While separating the first and second mold parts 260 and 270, the first mold part 260 is separated with the first lamp unit 210 and the second mold part 270 is separated with the second lamp unit 220. This is because the first and second lamp units 210 and 220 are combined to the first and second mold parts 260, 270, respectively.
In FIGS. 14 to 18, the top chassis 300 has only two sidewall portions 350 and 360. However, the top chassis 300 may be formed with four sidewall portions that combine to the first to fourth sidewalls 281, 282, 283 and 284, respectively. If the top chassis 300 is formed with the four sidewall portions, the top chassis 300 having the four sidewall portions has to be completely separated from the mold frame 280 before separating the first and second lamp units 210 and 220 from the LCD apparatus 500.

That is, when the mold frame 280 is received in the bottom chassis 400, the third and fourth engaging protrusions 282a and 284a are engaged into the fifth and sixth engaging holes 421 and 431, respectively, so that the mold frame 280 is fixed to the bottom chassis 400.
When the bottom chassis 400 is combined to the top chassis 300, the first and second sidewall portions 350 and 360 come in contact with the third and fourth sidewall portions 420 and 430. The third and fourth engaging protrusions 282a and 284a are engaged into the third and fourth engaging holes 351 and 361, thereby combining the top chassis 300 to the mold frame 280.
In FIGS. 19 to 21, the bottom chassis 400 has the third and fourth sidewall portions 420 and 430 and open portions corresponding to the first and third sidewalls 281 and 283 of the mold frame 280. Accordingly, the first and second lamp units 210 and 220 may be separated from the LCD apparatus 500 without separating the bottom chassis 400 from the mold frame 280.
However, the bottom chassis 400 may further include fifth and sixth sidewall portions (not shown) corresponding to the first and third sidewalls 281 and 283 of the mold frame 280. In this case, the bottom chassis 400 having the fifth and sixth sidewall portions has to be completely separated from the mold frame 280 before separating the first and second lamp units 210 and 220 from the LCD apparatus 500.
