However, display device 1 is not limited to outdoor installation; it can be installed anywhere, even indoors with high pedestrian traffic, such as in subway stations, shopping malls, theaters, offices, shops, etc.

[0066] Although display device 1 is illustrated in FIG. 1 as a display device with a flat screen, the display device according to the present disclosure can be similarly applied to curved display devices, or to flexible or bendable display devices that can change between a flat state and a curved state. The construction of the present disclosure can also be applied to many different types of display devices, regardless of the screen size or aspect ratio of the display device.

[0067] Display device 1 can receive content, including video and audio signals, from various content sources and output video and audio corresponding to those signals. For example, display device 1 can receive content data via a broadcast receiving antenna or cable, from a content playback device, or from a content provider's content delivery server.

[0068] Display device 1 can display images corresponding to video data and output sound corresponding to audio data. For example, display device 1 can reconstruct multiple image frames included in video data and display the multiple image frames continuously. In addition, display device 1 can reconstruct audio signals included in audio data and output sound continuously based on the audio signals.

[0069] As shown in Figure 1, the display device 1 may include a main body 11 and a screen 12 for displaying image I.

[0070] The display device 1 can be mounted upright on a floor or furniture, either outdoors or indoors, or it can be wall-mounted or mounted inside a wall. For example, the display device 1 may include a support leg 19 disposed below the main body 11 for upright mounting on a floor or furniture, either outdoors or indoors.

[0071] The main body 11 can define the exterior of the display device 1. Components for performing various functions such as displaying image I by the display device 1 can be arranged in the main body 11.

[0072] Display device 1 can be configured to display image I. Specifically, screen 12 can be formed on the front of body 11, and display device 1 can display image I through screen 12. For example, screen 12 can display a still image or a moving image.

[0076] Figure 2 is an exploded view of a display device according to some embodiments of the present disclosure.

[0077] Referring to Figure 2, the main body 11 of the display device 1 may be equipped with many different kinds of components for generating image I on screen 12.

[0078] For example, display device 1 may include display panel 20. Display panel 20 may be included in body 11. Display panel 20 may be configured to display the image I. Screen 12 as described above in conjunction with FIG. 1 may be formed on the front of display panel 20.

[0079] For example, the display panel 20 can be in an almost rectangular shape. Specifically, the display panel 20 can have different vertical and horizontal lengths. That is, the display panel 20 can have long sides and short sides. The shape of the display panel 20 can be set to resemble a rectangular plate. However, it is not limited to this; the display panel 20 can also be in the form of a square plate in which the long and short sides are almost the same.

[0080] The display panel 20 can be formed in various sizes. The ratio of the long side to the short side of the display panel 20 is not limited to general cases such as 16:9 or 4:3, but can be any ratio.

[0081] In embodiments of this disclosure, in display device 1, display panel 20 can be configured as a non-self-emissive display panel, such as a liquid crystal display (LCD).

[0082] A cable 20a and a display driver integrated circuit (DDI) 30 (hereinafter referred to as "driver IC") are disposed on one side of the display panel 20. The cable 20a is used to transmit image data to the display panel 20, and the display driver integrated circuit (DDI) 30 is used to process digital image data to output analog image signals.

[0083] Cable 20a can be electrically connected between printed circuit board assemblies (PBAs) 50, 60, and 70 and driver IC 30, and can also be electrically connected between driver IC 30 and display panel 20. Cable 20a may include flexible flat cable or bendable membrane cable.

[0084] The driver IC 30 can receive image data and power from PBA 50, 60 and 70 via cable 20a, and transmit image data and drive current to display panel 20 via cable 20a.

[0085] Furthermore, the cable 20a and the driver IC 30 can be integrated as a film cable, chip-on-film (COF), tape-on-package (TCP), etc. In other words, the driver IC 30 can be arranged on the cable 20a. However, it is not limited to this, and the driver IC 30 can also be arranged on the display panel 20.

[0086] The structure of the display panel 20 will be described in detail later.

[0087] Display device 1 may include a backlight unit 100 configured to emit light toward display panel 20. The backlight unit 100 may be disposed within body 11. The backlight unit 100 is positioned behind display panel 20 to emit light in a forward direction in which display panel 20 is located. Specifically, backlight unit 100 may be configured to have a surface light source. Display panel 20 may block or transmit light emitted from backlight unit 100.

[0088] The backlight unit 100 may include a point light source for emitting monochromatic light or white light, and the backlight unit 100 may be configured to refract, reflect, and diffuse the light emitted from the point light source to convert the light into uniform surface light.

[0092] As shown in Figure 2, the backlight unit 100 may include a reflective sheet 120 arranged to reflect light. The reflective sheet 120 can reflect light in a forward or nearly forward direction.

[0093] For example, the reflector 120 can be attached to the front surface of the light source module 1000. Specifically, the reflector 120 can be attached to the front surface of the light source substrate 1200.

[0094] For example, the light source module 1000 (specifically, the light source 1100 of the light source module 1000 (see Figure 4)) can emit light in various directions from the front of the reflector 120. The light emitted from the light source module 1000 can be emitted not only toward the diffuser 130 described below, but also toward the reflector 120, and the reflector 120 can reflect the light emitted to the reflector 120 toward the diffuser 130.

[0095] Furthermore, a portion of the light emitted from the light source module 1000 may be reflected from the surfaces of the diffuser plate 130 and the optical sheet 140, while passing through various objects such as the diffuser plate 130 and the optical sheet 140. In this case, the reflector plate 120 can reflect the reflected light back in the forward direction.

[0096] As shown in Figure 2, the backlight unit 100 may include a diffuser plate 130 arranged to uniformly diffuse light. The diffuser plate 130 may be arranged in front of the light source module 1000 and the reflector 120. The diffuser plate 130 can uniformly diffuse the light emitted from the light source module 1000 and then emit light in a forward direction.

[0097] As shown in Figure 2, the backlight unit 100 may include an optical sheet 140 arranged to enhance the brightness and brightness uniformity of the emitted light. The optical sheet 140 may be arranged to refract and scatter light emitted from the front surface of the diffuser plate 130. For example, the optical sheet 140 may include various types of sheets, such as diffuser sheets, prism sheets, reflective polarizers, quantum dot sheets, etc.

[0098] Display device 1 may include: a main board 50 and a driver board 70 for controlling the operation of the backlight unit 100 and the display panel 20, and a power supply board 60 for supplying power to the backlight unit 100 and the display panel 20. The main board 50, the power supply board 60 and the driver board 70 may be electrically connected to each other. The main board 50, the power supply board 60 and the driver board 70 may be arranged in the main body 11.

[0099] The motherboard and / or driver board 70 may include control circuitry for controlling the operation of the display panel 20 and the backlight unit 100. The control circuitry may process image data received from an external content source, transmit image data to the display panel 20, and transmit dimming data to the backlight unit 100.

[0100] For example, motherboard 50 can process video / audio signals to output content data in a format that can be output from display panel 20 or speakers. Motherboard 50 can control driver board 70. Motherboard 50 can be connected to display panel 20 to control display panel 20.

[0101] The driver board 70 can be connected to the light source module 1000 to control the light source module 1000. The driver board 70 can transmit drive current to the light source module 1000 based on the control signals of the main board 50. The driver board 70 can be connected to the light source substrate 1200 (see Figure 4) to control the on / off operation of multiple light sources 1100 (see Figure 4).

[0102] The power board 60 can supply power to the display panel 20 and the backlight unit 100 to enable the backlight unit 100 to output surface light and to enable the display panel 20 to block or transmit light from the backlight unit 100.

[0103] Although the motherboard 50, driver board 70 and power board 60 are illustrated as separate board assemblies in Figure 2, the motherboard 50, driver board 70 and power board 60 can be configured in an integrated board assembly.

[0104] Each of the PBAs 50, 60, and 70 can be implemented using a printed circuit board (PCB) and various circuits mounted on the PCB. For example, the power supply circuitry may include a power supply board and capacitors, coils, resistors, processors, etc., mounted on that power supply board.

[0107] For example, the display device 1 may include a top housing 13. The top housing 13 may support the front or side of the display panel 20. For example, the top housing 13 may be shaped like a substantially rectangular frame.

[0108] The top housing 13 may form a bezel facing the front of the display device 1 to support the front of the display panel 20. However, if the display device 1 is a bezel-less display device with no bezel or a very narrow bezel, the top housing 13 may be arranged to support only the sides of the display panel 20. Alternatively, when the bottom housing 15 supports the sides of the display panel 20, the display device 1 may not include the top housing 13.

[0109] For example, the display device 1 may include a bottom housing 15. The bottom housing 15 may cover the back of the display panel 20. The bottom housing 15 may be connected to the back of the top housing 13. The bottom housing 15 may support various parts of the display device 1, such as the backlight unit 100, the motherboard 50, the power board 60, the driver board, etc.

[0110] The bottom housing 15 can be formed in a substantially flat shape, but is not limited thereto. The bottom housing 15 can be formed to include a material with high thermal conductivity so as to radiate heat generated from the backlight unit 100 to the outside. For example, the bottom housing 15 can be formed to have a metallic material such as aluminum, SUS, etc., or a plastic material such as ABS.

[0111] For example, the display device 1 may include an intermediate frame 14. The intermediate frame 14 may be disposed between the top housing 13 and the bottom housing 15. For example, the intermediate frame 14 may support at least some components of the backlight unit 100.

[0112] For example, the display device 1 may include a rear cover 16. The rear cover 16 may be placed behind the bottom housing 15 to cover the bottom housing 15 and various components (e.g., motherboard 50, power board 60, driver board 70, etc.) mounted on the back of the bottom housing 15.

[0113] Meanwhile, unlike that shown in Figure 2, the display housing of display device 1 may not include some of the top housing, middle frame, bottom housing, and rear cover.

[0114] The configuration of display device 1 described above in conjunction with Figure 2 is merely an example of a display device according to this disclosure, but is not limited thereto. A display device according to this disclosure can be configured to include various components for performing functions of providing images through a screen.

[0115] Figure 3 is a cross-sectional view of a liquid crystal panel of a display device according to some embodiments of the present disclosure.

[0116] Referring to Figure 3, the display panel 20 included in the display device 1 can be configured as a liquid crystal display (LCD) panel to block or transmit light emitted from the backlight unit 100. By blocking or transmitting light emitted from the backlight unit 100 through the display panel 20, an image I is formed on the front of the display panel 20.

[0117] The front surface of the display panel 20 can form the aforementioned screen 12 of the display device 1. A plurality of pixels P can be arranged on the display panel 20. The plurality of pixels P arranged on the display panel 20 can each individually block or transmit light from the backlight unit 100, and the light that has passed through the plurality of pixels P can form an image I to be displayed on the screen 12.

[0118] For example, as shown in FIG3, the display panel 20 may include a first polarizing film 21, a first transparent substrate 22, a pixel electrode 23, a thin film transistor (TFT) 24, a liquid crystal layer 25, a common electrode 26, a color filter 27, a second transparent substrate 28, and a second polarizing film 29.

[0119] The first transparent substrate 22 and the second transparent substrate 28 can firmly support the pixel electrode 23, TFT 24, liquid crystal layer 25, common electrode 26, and color filter 27. The first transparent substrate 22 and the second transparent substrate 28 can be formed of tempered glass or transparent resin.

[0120] A first polarizing film 21 and a second polarizing film 29 may be applied or coated on the outer surface of the first transparent substrate 22 and the outer surface of the second transparent substrate 28, respectively.

[0121] The first polarizing film 21 and the second polarizing film 29 can each transmit specific types of light while blocking other light. For example, the first polarizing film 21 transmits light with a magnetic field oscillating in a first direction while blocking other light. The second polarizing film 29 transmits light with a magnetic field oscillating in a second direction while blocking other light. The first and second directions can be perpendicular to each other. Therefore, the polarization direction of the light transmitted by the first polarizing film 21 and the oscillation direction of the light transmitted by the second polarizing film 29 can be perpendicular to each other. As a result, light generally cannot pass through both the first polarizing film 21 and the second polarizing film 29 simultaneously.

[0122] The color filter 27 can be arranged on the inside of the second transparent substrate 28.

[0123] The color filter 27 may include, for example, a red color filter 27R for transmitting red light, a green color filter 27G for transmitting green light, and a blue color filter 27B for transmitting blue light, and the red color filter 27R, green color filter 27G, and blue color filter 27B may be arranged side by side. The area in which the color filter 27 is formed may correspond to pixel P as described above. The area in which the red color filter 27R is formed may correspond to red sub-pixel P. R The region in which the green filter 27G is formed can correspond to the green sub-pixel P. G The region in which the blue filter 27B is formed can correspond to the blue sub-pixel P. B .

[0124] The pixel electrode 23 can be disposed on the inner side of the first transparent substrate 22, and the common electrode 26 can be disposed on the inner side of the second transparent substrate 28.

[0125] The pixel electrode 23 and the common electrode 26 are formed of a conductive metal material and can generate an electric field to change the layout of the liquid crystal molecules 25a that form the liquid crystal layer 25, which will be described below.

[0126] The pixel electrode 23 and the common electrode 26 can be formed of a transparent material to transmit incident light from the outside. For example, the pixel electrode 23 and the common electrode 26 can also be formed of indium tin oxide (ITO), indium zinc oxide (IZO), silver (Ag) nanowires, carbon nanotubes (CNTs), graphene, or 3,4-ethylenedioxythiophene (PEDOT). The TFT 24 can be disposed inside the second transparent substrate 28.

[0127] TFT 24 can transmit or block current flow to pixel electrode 23. For example, depending on whether TFT 24 is on (closed) or off (open), an electric field can be formed or removed between pixel electrode 23 and common electrode 26.

[0128] TFT 24 can be formed from polycrystalline silicon and can be formed using semiconductor processes such as photolithography, deposition or ion implantation.

[0129] The liquid crystal layer 25 can be formed between the pixel electrode 23 and the common electrode 26. The liquid crystal layer 25 can be filled with liquid crystal molecules 25a.

[0130] Liquid crystals exist in an intermediate state between solids (crystals) and fluids. Most liquid crystal materials are organic compounds whose molecules are shaped like thin, elongated rods, and whose arrangement is irregular in one direction and regular in another. As a result, liquid crystals can possess both the fluidity of liquids and the optical anisotropy of crystals (solids).

[0131] Furthermore, liquid crystals can exhibit optical properties depending on changes in the electric field. For example, depending on changes in the electric field, the liquid crystal can have a changing alignment direction of the molecules forming the liquid crystal. When an electric field is generated in the liquid crystal layer 25, the liquid crystal molecules 25a of the liquid crystal layer 25 can align along the direction of the electric field, and conversely, when no electric field is generated in the liquid crystal layer 25, the liquid crystal molecules 25a can align irregularly or along the alignment layer. Therefore, the optical properties of the liquid crystal layer 25 can change depending on the presence or absence of an electric field passing through the liquid crystal layer 25.

[0132] The structure of the display panel 20 described above in conjunction with Figure 3 is merely an example of a display panel according to this disclosure, but is not limited thereto.

[0133] Figure 4 is an enlarged view of the light source and reflector of a display device according to some embodiments of the present disclosure.

[0134] Referring to Figure 4, the display device 1 may include multiple light sources 1100 and a light source substrate 1200, with the light sources 1100 mounted on the light source substrate 1200. The multiple light sources 1100 and the light source substrate 1200 can constitute the light source module 1000 of the backlight unit 100.

[0135] Figure 4 shows one of the multiple light sources 1100 included in the light source module 1000, and the structure and function of the light source 1100 described in conjunction with Figure 4 will now be commonly applied to each of the multiple light sources 1100.

[0136] The light source 1100 can be arranged to emit light. The light source 1100 can be arranged to emit light toward the display panel 20. The light source 1100 can be a device capable of emitting monochromatic light (light with a specific wavelength, such as blue light) or white light (a mixture of red, green and blue light) in various directions when powered. For example, the light source 1100 may include a light-emitting diode (LED).

[0137] The light source substrate 1200 can fix multiple light sources 1100 to prevent the light sources 1100 from moving. In addition, the light source substrate 1200 can supply power to each light source 1100 so that the light source 1100 can emit light.

[0138] The light source substrate 1200 can fix multiple light sources 1100 and can be formed from synthetic resin, conical glass or PCB with conductive power supply lines formed therein to supply power to the light sources 1100.

[0139] The light source 1100 can be disposed on the front surface of the light source substrate 1200. The front surface of the light source substrate 1200 can refer to the surface of the light source substrate 1200 facing the display panel 20. In other words, the light source 1100 can be mounted on the light source substrate 1200 to face forward and is arranged to emit light forward.

[0140] The reflector 120 can be placed in front of the light source substrate 1200. As described above, the reflector 120 can be attached to the front surface of the light source substrate 1200. In this case, the reflector 120 may include a plurality of through holes 120a formed at positions that respectively match the plurality of light sources 1100 of the light source module 1000. As shown in FIG4, the light source 1100 can pass through the through holes 120a and protrude forward from the reflector 120. Therefore, the light source 1100 and a portion of the light source substrate 1200 can be exposed forward from the reflector 120 through the through holes 120a. With this structure, the light source 1100 can emit light from the front of the reflector 120.

[0141] The reflector 120 can reflect light emitted from the light source 1100 toward the reflector 120 toward the diffuser 130.

[0142] The process by which light emitted by multiple light sources 1100 and light reflected by reflector 120 propagates to display panel 20 is the same as described above.

[0143] The detailed structure of the light source 1100 and the light source substrate 1200 will now be described as an example.

[0144] The light source 1100 may include a light-emitting diode (LED) 1101. The LED 1101 may include a p-type semiconductor and an n-type semiconductor to emit light based on the recombination between holes and electrons. In addition, the LED 1101 may be equipped with a pair of electrodes to apply holes and electrons to the p-type semiconductor and the n-type semiconductor, respectively.

[0145] LED 1101 can be configured to convert electrical energy into light energy. LED 1101 can emit light with the highest intensity at a predetermined wavelength based on the supplied power. For example, LED 1101 can emit blue light with a peak at a wavelength representing blue (e.g., between 450 nm and 495 nm).

[0146] For example, a multi-layer reflective structure can be provided on the front of the LED 110, in which multiple insulating films with different refractive indices are alternately stacked. For example, the multi-layer reflective structure can be formed by a distributed Bragg reflector (DBR).

[0147] For example, LED 1101 can be directly attached to the light source substrate 1200 using a chip-on-board (COB) method. In other words, the light source 1100 may include LED 1101, wherein the LED chip or LED die is directly attached to the light source substrate 1200 without additional packaging.

[0148] The light source module 1000 is manufactured by attaching flip-chip type LEDs 1101 to the light source substrate 1200 using the COB method, which makes the light source 1100 compact.

[0149] The light source of substrate 1200 may include a power supply line 1230 configured to supply power to light source 1100. Power supply line 1230 may be configured to supply electrical signals and / or power to light source 1100 from PBAs 50, 60, and 70. For example, power supply line 1230 may be configured to supply power to a flip-chip type LED 1101.

[0150] For example, a light source substrate 1200 can be formed by alternately stacking non-conductive insulating layers and conductive layers.

[0151] Lines or patterns for transmitting power and / or electrical signals can be formed on the conductive layer of the light source substrate 1200. The conductive layer can be formed of various conductive materials. For example, the conductive layer can be formed of various metallic substances, such as copper (Cu), tin (Sn), aluminum (Al), or alloys thereof. The power supply line 1230 can be implemented as a line or pattern formed on the conductive layer of the light source substrate 1200.

[0152] The dielectric of the insulating layer can insulate the gaps between the lines or patterns of the conductive layer. The insulating layer can be formed of a dielectric used for electrical insulation (e.g., FR-4).

[0153] For example, a protective layer may be disposed on the outer surface of the light source substrate 1200 to prevent or suppress damage to the light source substrate 1200 caused by external impact and / or chemical action (e.g., corrosion) and / or damage caused by optical action. For example, the protective layer of the light source substrate 1200 may include a photosensitive solder resist (PSR).

[0154] The power supply line can be covered by the protective layer of the light source substrate 1200, and the power supply line 1230 is prevented from being exposed to the outside.

[0155] For example, the light source substrate 1200 may include a power supply pad 1240 electrically connected to a power supply line 1230 to supply power to a flip-chip type LED 1101. The power supply line 1230 can be electrically connected to the LED 1101 through the power supply pad 1240.

[0156] For example, a window can be formed on the protective layer of the light source substrate 1230 to expose a portion of the power supply line 1230 to the outside. The power supply pad 1240 can be electrically connected to the portion of the power supply line 1230 exposed to the outside of the light source substrate 1200.

[0157] For example, a variety of conductive adhesives, such as solder, conductive epoxy resin adhesive, etc., can be applied or coated between the electrode of LED 1101 and the power supply pad 1240.

[0158] The light source 1100 may include an optical dome 1102. The optical dome 1102 may cover the LED 1101. The optical dome 1102 may prevent or suppress damage to the LED 1101 caused by external mechanical and / or chemical actions.

[0159] The shape of the optical dome 1102 can be formed similar to, for example, a dome obtained by cutting a sphere without including the center, or a hemisphere obtained by cutting a sphere with including the center. The vertical cross-section of the optical dome 1102 can be, for example, arcuate or semicircular.

[0160] The optical dome 1102 can be formed of silicone or epoxy resin. For example, molten silicone or epoxy resin is discharged onto the LED 1101 through, for example, a nozzle, and then cured to form the optical dome 1102.

[0161] The optical dome 1102 can be optically transparent or translucent. Light emitted from the LED 1101 can pass through the optical dome 1102 to the outside.

[0162] In this case, for example, the dome-shaped optical dome 1102 can refract light like a lens. For example, light emitted from LED 1101 can be refracted and dispersed by the optical dome 1102.

[0163] The structure of the light source module 1000 having a light source 1100 and a light source substrate 1200 as described above in conjunction with Figure 4 is merely an example of a light source module for a display device according to this disclosure, but is not limited thereto.

[0164] Figure 5 illustrates a light source substrate of a display device according to some embodiments of the present disclosure.

[0165] Referring to FIG5, in some embodiments of this disclosure, the display device 1 may include a light source module 1000. The display device 1 may include a plurality of light source modules 1000, and the description of the structure and properties of one light source module 1000 described in conjunction with FIG5 will now be equally applied to each of the plurality of light source modules 1000.

[0166] The light source module 1000 may include a plurality of light sources 1100 and a light source substrate 1200, wherein the plurality of light sources 1100 are mounted on the light source substrate 1200. The light source substrate 1200 may support the plurality of light sources 1100. The light source substrate 1200 may include power supply lines 1230 configured to supply drive current to the plurality of light sources 1100.

[0167] The light source substrate 1200 can be placed in front of the bottom housing 15 (in the +X direction). The light source substrate 1200 can be mounted on the bottom housing 15. The light source substrate 1200 can be fixed and supported by the bottom housing 15.

[0168] The light source substrate 1200 may include multiple substrate strips 1220.

[0169] The substrate strip 1220 is a component constituting at least a part of the light source substrate 1200, including a PCB having a shape extending in one direction.

[0170] At least some of the multiple light sources 1100 can be mounted on each of the multiple substrate strips 1220. At least some of the multiple light sources 1100 can be mounted on the front surface of the multiple substrate strips 1220. The front surface of the multiple substrate strips 1220 refers to the surface of the multiple substrate strips 1220 that faces the display panel 20.

[0171] Multiple substrate strips 1220 can be formed from a PCB, the light source 1100 is mounted on the PCB, and the aforementioned power supply line 1230 is arranged on the PCB.

[0172] Multiple substrate strips 1220 can be arranged along a first direction Z. For example, multiple substrate strips 1220 can be arranged along an almost vertical direction of the display device 1.

[0173] Multiple substrate strips 1220 can be arranged to be spaced apart from each other. The multiple substrate strips 1220 can be arranged to be spaced apart from each other along a first direction Z. For example, the first direction Z along which the multiple substrate strips 1220 are arranged to be spaced apart from each other can be almost parallel to the vertical direction (up-down direction) of the display device 1. The multiple substrate strips 1220 can be arranged to be parallel to each other at the spaced-out positions.

[0174] The shapes of the plurality of substrate strips 1220 can each be configured to resemble strips. Specifically, each of the plurality of substrate strips 1220 can have a width in a first direction Z and extend elongatedly in a second direction Y, different from the first direction Z. In other words, each of the plurality of substrate strips 1220 can be formed to have a length in the second direction Y that is longer than its width in the first direction Z. The second direction Y can also be referred to as the strip direction along which each of the plurality of substrate strips 1220 extends.

[0175] For example, the width direction of each of the plurality of substrate strips 1220 may be almost parallel to the vertical direction (vertical direction) of the display device 1. For example, the direction in which each of the plurality of substrate strips 1220 extends may be almost parallel to the horizontal direction (e.g., horizontal direction).

[0176] For example, the direction in which each of the plurality of substrate strips 1220 extends may be parallel to the direction of the long side of the display device 1. For example, the direction of the width of each of the plurality of substrate strips 1220 may be parallel to the direction of the short side of the display device 1. Specifically, the plurality of substrate strips 1220 may be arranged along the direction of the short side of the display device 1 and may extend in the direction of the long side of the display device 1.

[0177] The plurality of substrate strips 1220 are arranged to be spaced apart from each other in a direction that may be parallel to the direction of each width. In other words, the plurality of substrate strips 1220 may be arranged to be spaced apart from each other along a first direction Z (which is the direction of each width).

[0178] Each of the plurality of substrate strips 1220 may extend in a direction different from the direction along which the plurality of substrate strips 1220 are spaced apart from each other. Specifically, each of the plurality of substrate strips 1220 may extend in a direction Y that is perpendicular to the direction Z along which the plurality of substrate strips 1220 are spaced apart from each other. That is, the first direction and the second direction may be perpendicular to each other.

[0179] Alternatively, the direction along which the plurality of substrate strips 1220 are arranged to be spaced apart from each other and the direction along which each of the plurality of substrate strips 1220 extends can form an angle, which may not be a precise right angle.

[0180] For example, the plurality of substrate strips 1220 can be arranged to be spaced apart at regular intervals in the first direction Z. In other words, the spacing between pairs of adjacent substrate strips 1220 in the first direction Z can be almost the same. This can increase the uniformity of brightness of the display device 1.

[0181] For example, the plurality of substrate strips 1220 may be formed to have corresponding shapes. For example, the plurality of substrate strips 1220 may have corresponding widths in the first direction Z. For example, the plurality of substrate strips 1220 may have corresponding lengths extending in the second direction Y. For example, the plurality of substrate strips 1220 may be formed to have corresponding dimensions.

[0182] Each of the plurality of substrate strips 1220 can be mounted on the bottom housing 15. Because each of the plurality of substrate strips 1220 is mounted on the bottom housing 15 and held in a fixed position, the plurality of light sources 1100 mounted on the plurality of substrate strips 1220 can be stably placed in their respective designed positions. For example, each of the plurality of substrate strips 1220 can be mounted on the bottom housing 15 by means of a substrate holder 200 for securing the light source substrate 1200 to the bottom housing 15.

[0183] Multiple substrate strips 1220 can also be supported more stably by strip support members 300. For example, each strip support member 300 can be connected to a pair of adjacent substrate strips 1220, so that the pairs of substrate strips 1220 can be arranged to be supported more stably.

[0184] However, the structure in which multiple substrate strips 1220 are mounted or stably supported on the bottom housing 15 is not limited to the structure described above (including substrate holders 200, strip supports 300, etc.).

[0185] The reflector 120 can be attached to the front surface of each of the plurality of substrate strips 1220.

[0186] The light source substrate 1200 may include a substrate body 1210. The substrate body 1210 is a component forming a part of the light source substrate 1200, and may include a PCB.

[0187] Multiple substrate strips 1220 can be connected to a substrate body 1210. The multiple substrate strips 1220 can be supported by the substrate body 1210. For example, the multiple substrate strips 1220 can be connected to one side of the substrate body 1210.

[0188] Multiple substrate strips 1220 may extend from the substrate body 1210. For example, each of the multiple substrate strips 1220 may extend from the substrate body 1210 in a second direction Y. For example, each of the multiple substrate strips 1220 may extend from one side of the substrate body 1210 in the second direction Y. Each of the multiple substrate strips 1220 may extend from the substrate body 1210 in a strip direction.

[0189] The substrate body 1210 may extend in a first direction Z. For example, the substrate body 1210 may be formed to have a length in the first direction Z that is longer than its width in the second direction Y. Because the substrate body 1210 extends in the direction along which the plurality of substrate strips 1220 are arranged, the substrate body 1210 may have a structure that connects to more substrate strips 1220. Furthermore, in this case, since the plurality of substrate strips 1220 extend from one side of the second direction Y, which is the width direction of the substrate body 1210 (i.e., the direction of the relatively shorter length), each of the plurality of substrate strips 1220 may have a form that extends longer from the substrate body 1210.

[0190] The substrate body 1210 can be mounted on the bottom housing 15. Because the substrate body 1210 is mounted on the bottom housing 15 and held in a fixed position, the multiple light sources 1100 mounted on the substrate body 1210 can be stably placed in their respective designed positions. Furthermore, because the substrate body 1210 is mounted on the bottom housing 15, the multiple substrate strips 1220 connected to the substrate body 1210 can be more stably supported by the substrate body 1210.

[0191] For example, the substrate body 1210 can be mounted on the bottom housing 15 by a substrate holder 200 for fixing the light source substrate 1200 to the bottom housing 15. However, the structure in which the substrate body 1210 is mounted or stably supported on the bottom housing 15 is not limited to the structure described above (with substrate holder 200, etc.).

[0192] For example, some of the multiple light sources 1100 may be mounted on the substrate body 1210. Some of the multiple light sources 1100 may be mounted on the front surface of the substrate body 1210. The front surface of the substrate body 1210 refers to the side of the substrate body 1210 in the direction along which the substrate body 1210 points toward the display panel 20.

[0193] The substrate body 1210 can be formed by a PCB, the light source 1100 is mounted on the PCB, and the aforementioned power supply line 1230 is arranged on the PCB.

[0194] The reflective sheet 120 can be attached to the front surface of the substrate body 1210. For example, an integral reflective sheet 120 can be attached to the front surface of the substrate body 1210 and the front surfaces of the plurality of substrate strips 1220. In this case, the brightness uniformity of the light reflected by the reflective sheet 120 can be enhanced, and the process of attaching the reflective sheet 120 to the front surface of the substrate body 1210 and the front surfaces of the plurality of substrate strips 1220 can be simplified. However, it is not limited to this, and a plurality of reflective sheets 120 that are separate from each other can be attached to the front surface of the substrate body 1210 and the front surfaces of the plurality of substrate strips 1220.

[0195] For example, as shown in FIG5, the substrate body 1210 and the plurality of substrate strips 1220 can be integrally formed. In other words, the substrate body 1210 and the plurality of substrate strips 1220 can be connected to each other to form an integral light source substrate 1200. The light source substrate 1200 can be formed from an integrated PCB including the substrate body 1210 and the plurality of substrate strips 1220. Alternatively, the substrate body 1210 and the plurality of substrate strips 1220 are not integrally formed, but are separate parts that can be connected to each other through an assembly process.

[0196] Although in the embodiment of this disclosure shown in FIG. 5, each of the plurality of substrate strips 1220 extends to the right (in the +Y direction) from the substrate body 1210, this disclosure is not limited thereto, and for example, the plurality of substrate strips 1220 may extend to the left (in the -Y direction) from the substrate body 1210.

[0197] Furthermore, in the embodiment of this disclosure shown in FIG5, the substrate body 1210 extends in the vertical direction (in the Z direction) of the display device 1, but this disclosure is not limited thereto, and for example, the substrate body 1210 may extend horizontally (in the Y direction).

[0198] Furthermore, in the embodiment of this disclosure shown in FIG. 5, each of the plurality of substrate strips 1220 extends horizontally (in the Y direction) from one side of the horizontal direction Y of the substrate body 1210. However, this disclosure is not limited thereto, and for example, each of the plurality of substrate strips 1220 may extend vertically (in the Z direction) from one side of the vertical direction Z of the substrate body 1210. In this case, the plurality of substrate strips 1220 may be arranged to be spaced apart from each other in the horizontal direction Y.

[0199] Unlike the description above, the first direction of the width direction of each of the plurality of substrate strips 1220, the first direction along which the plurality of substrate strips 1220 are arranged to be spaced apart from each other, the first direction along which the substrate body 1210 extends, and the second direction along which each of the plurality of substrate strips 1220 extends, may not be parallel to either the vertical direction Z or the horizontal direction Y of the display device 1.

[0200] However, for ease of explanation, an embodiment will now be described focusing on which the first direction is parallel to the vertical direction Z of the display device 1 and the second direction is parallel to the horizontal direction Y of the display device 1.

[0201] Display device 1 may include a connector 1300 disposed on a light source substrate 1200. The connector 1300 may be electrically connected to a plurality of light sources 1100. The connector 1300 may be electrically connected to the light source substrate 1200. The connector 1300 may be electrically connected to various electronic components (e.g., the plurality of light sources 1100) mounted on the light source substrate 1200 via a power supply line 1230 disposed on the light source substrate 1200. Furthermore, the connector 1300 may be arranged to be electrically connected to a driver board 70 via a wire C (see FIG. 7). Therefore, the connector 1300 can transmit drive signals from the driver board 70 to various electronic components (e.g., the plurality of light sources 1100) mounted on the light source substrate 1200. In other words, the light source module 1000 may be electrically connected to the driver board 70 via the connector 1300, and the light source module 1000 may receive drive current from the driver board 70 via the connector 1300.

[0202] For example, connector 1300 can be mounted on substrate body 1210. Specifically, connector 1300 can be mounted on the rear surface of substrate body 1210. The rear surface of substrate body 1210 refers to a surface of substrate body 1210 facing the bottom housing 15. The rear surface of substrate body 1210 also refers to the surface opposite to the front surface of substrate body 1210 that points to display panel 20 and on which multiple light sources 1100 are mounted.

[0203] As shown in Figure 5, for example, connector 1300 can be positioned near the center of substrate body 1210. Specifically, connector 1300 can be positioned near the center of substrate body 1210 in the first direction Z. The statement "connector 1300 is positioned near the center of substrate body 1210 in the first direction Z" does not precisely mean that the connector 1300 is placed at a distance from one end (e.g., the upper end) of substrate body 1210 in the first direction Z equal to the distance to the other end (e.g., the lower end). With this structure of connector 1300, even when substrate strip 1220 is positioned on either side of substrate body 1210 of light source substrate 1200, the position of connector 1300 in the first direction Z (i.e., the height of connector 1300 in the vertical direction of display device 1) does not change significantly, thereby improving the efficiency of product design and manufacturing tasks.

[0204] Connector 1300 will be described in more detail later.

[0205] The display device 1 may include a plurality of driving devices 1400 mounted on a light source substrate 1200. The plurality of driving devices 1400 may be configured to control at least some of the plurality of light sources 1100 mounted on the same light source substrate 1200.

[0206] Multiple drive units 1400 can be mounted on the light source substrate 1200 and electrically connected to the power supply line 1230. The multiple drive units 1400 can be electrically connected to the drive board 70 through components such as the power supply line 1230 and the connector 1300.

[0207] For example, multiple light sources 1100 can be divided into multiple dimming blocks, each dimming block including at least one light source 1100, and multiple driving devices 1400 can output dimming signals to control the multiple dimming blocks.

[0208] For example, multiple drive devices 1400 can be implemented using pixel integrated circuits (ICs) or active matrix integrated circuits (AM ICs).

[0209] For example, as shown in FIG5, a plurality of drive devices 1400 may be mounted on the front surface of the substrate body 1210. The front surface of the substrate body 1210 refers to the surface of the substrate body 1210 facing the display panel 20. Alternatively, the plurality of drive devices 1400 may be mounted on the rear surface of the substrate body 1210. The rear surface of the substrate body 1210 refers to the surface facing the bottom housing 15, opposite to the front surface of the substrate body 1210.

[0210] For example, multiple drive units 1400 can be arranged side by side in the first direction Z. In other words, multiple drive units 1400 can be arranged side by side in the vertical direction of the display device 1. Not limited to this, multiple drive units 1400 can be arranged in various ways.

[0211] Figure 6 is an enlarged view of some adjacent light source substrates in a light source substrate of a display device according to some embodiments of the present disclosure.

[0212] Referring to FIG6, in some embodiments of this disclosure, the display device 1 may include a plurality of light source modules 1000. The display device 1 may include a plurality of light sources 1100 and a plurality of light source substrates 1200, each light source substrate 1200 having a plurality of light sources 1100 mounted on the light source substrate 1200.

[0213] For example, multiple light source modules 1000 can be formed in corresponding forms. In other words, the multiple light source modules 1000 can have almost identical structures. Because the multiple light source modules 1000 are designed to have almost identical structures, waste of parts can be prevented, and the efficiency of the manufacturing process can be improved, thereby saving production costs or manufacturing expenses. However, this is not a limitation; at least some of the multiple light source modules 1000 can be formed in different forms.

[0214] For example, some of the multiple light source modules 1000 can be arranged side-by-side in the first direction Z, and the other light source modules 1000 can be arranged side-by-side in the second direction Y. In other words, the multiple light source modules 1000 can be arranged in columns extending along the first direction Z and rows extending along the second direction Y. As shown in Figure 6, the multiple light source modules 1000 can be arranged in rows extending along the horizontal direction Y and columns extending along the vertical direction Z.

[0215] Multiple light source modules 1000 can be configured such that the multiple light sources 1100 are arranged at regular intervals. The multiple light sources 1100 can be arranged at regular intervals in the vertical direction Z and at regular intervals in the horizontal direction Y.

[0216] For example, referring to Figure 6, the horizontal distance dy1 (hereinafter referred to as the first horizontal distance) between a pair of adjacent light sources 1100p and 1100q on a light source substrate 1200 among a plurality of light sources 1100 can be constant in the horizontal direction Y. The first horizontal distance can refer to the shortest distance in the horizontal direction Y between a pair of light sources 1100 among a plurality of light sources 1100 mounted on a light source substrate 1200, and the first horizontal distance dy1 between a pair of adjacent light sources 1100 on a light source substrate 1200 can be constant.

[0217] Referring to Figure 6, the distance dy2 (hereinafter referred to as the second horizontal distance) between a light source 1100p, one of a plurality of light sources 1100 included in a light source module 1000, and a light source 1100s, one of a plurality of light sources 1200 included in another light source module 10000, arranged closest to the light source 1100p in the horizontal direction Y, can be constant. The second horizontal distance dy2 can be equal to the first horizontal distance dy1. In other words, a pair of adjacent light source substrates 1200 in the horizontal direction Y can be arranged such that the first horizontal distance dy1 and the second horizontal distance dy2 of the plurality of light sources 1100 mounted on the pair of adjacent light source substrates 1200 are the same.

[0218] Furthermore, referring to Figure 6, the vertical distance dz1 (hereinafter referred to as the first vertical distance) between a pair of adjacent light sources 1100p and 1100r on a light source substrate 1200 among the plurality of light sources 1100 can be constant in the vertical direction Z. The first vertical distance can refer to the shortest distance in the vertical direction Z between a pair of light sources 1100 among the plurality of light sources 1100 mounted on a light source substrate 1200, and the first vertical distance dz1 between a pair of adjacent light sources 1100 on a light source substrate 1200 in the vertical direction Z can be constant.

[0219] Referring to Figure 6, the distance dz2 (hereinafter referred to as the second vertical distance) between a light source 1100p, one of a plurality of light sources 1100 included in a light source module 1000, and a light source 1100t, one of a plurality of light sources 1100 included in another light source module 1000, which is arranged closest to the light source 1100p in the vertical direction Z, can be constant. The second vertical distance dz2 can be equal to the first vertical distance dz1. In other words, a pair of adjacent light source substrates 1200 in the vertical direction Z can be arranged such that the first vertical distance dz1 and the second vertical distance dz2 of the plurality of light sources 1100 mounted on the pair of light source substrates 1200 are the same.

[0220] Furthermore, the first horizontal spacing dy1, the second horizontal spacing dy2, the first vertical spacing dz1, and the second vertical spacing dz2 can all be set to be the same.

[0221] The aforementioned layout of the light source module 1000 can be applied to the layout of multiple adjacent light source modules 1000 in the horizontal direction Y or the vertical direction Z. Utilizing the layout and structure of the light source modules 1000, multiple light sources 1100 can be arranged at regular intervals in the horizontal direction Y and the vertical direction Z, and therefore, the display device 1 can provide uniform brightness.

[0222] As will be described later, the light source substrate 1200 can be arranged such that the substrate body 1210 is positioned further to the left (in the -Y direction) or to the right (in the +Y direction) than the plurality of substrate strips 1220 as needed. In this case, with the layout and structure of the light source module 1000 having constant first horizontal spacing dy1, second horizontal spacing dy2, first vertical spacing dz1 and second vertical spacing dz2, the plurality of light sources 1100 can be arranged at regular intervals, regardless of the layout of the light source substrate 1200 (i.e., in which direction the substrate body 1210 is positioned relative to the plurality of substrate strips 1220).

[0223] Figure 7 illustrates a connector, a wire connected to the connector, and a portion of the bottom housing of a display device according to some embodiments of the present disclosure.

[0224] Referring to FIG. 7, in display device 1, a plurality of light source substrates 1200 can be electrically connected to at least some of the PBAs 50, 60, and 70 via wires C. Specifically, as shown in FIGS. 8 and 9, each of the plurality of light source substrates 1200 can be electrically connected to a driver board 70 via wire C. Each of the plurality of light source substrates 1200 can be connected to wire C, which is electrically connected to the driver board 70. Each of the plurality of light source substrates 1200 can receive a drive signal from the driver board 70 via wire C.

[0225] For example, wire C may include flexible flat cable or membrane cable.

[0226] As described above, the light source substrate 1200 can be arranged in front of the bottom housing 15, while the drive board 70 can be arranged behind the bottom housing 15. The wire C connected to the drive board 70 can be arranged behind the bottom housing 15.

[0227] The display device 1 may include a plurality of connectors 1300 disposed on a plurality of light source substrates 1200. At least one connector 1300 may be disposed on one light source substrate 1200. One or more of the plurality of connectors 1300 may be disposed on the substrate body 1210 of each of the plurality of light source substrates 1200.

[0228] Each of the plurality of connectors 1300 can be connected to wire C. Each of the plurality of connectors 1300 can be electrically connected to the driver board 70 via wire C. Each of the plurality of connectors 1300 can be connected to wire C so that each of the plurality of light source substrates 1200 is electrically connected to the driver board 70. Because the connectors 1300 mounted on the light source substrate 1200 are connected to wire C, the light source substrate 1200 can be electrically connected to the driver board 70.

[0229] As described above, each of the plurality of connectors 1300 can be arranged on the rear surface of the light source substrate 1200. Specifically, the plurality of connectors 1300 can be arranged on the rear surface of the substrate body 1210.

[0230] In this configuration, multiple connectors 1300 can each be arranged to pass through the bottom housing 15. The bottom housing 15 may include connector holes 15c, and the connectors 1300 can be arranged to pass through the connector holes 15c. The connectors 1300 can pass through the connector holes 15c and thus can be connected to a wire C disposed at the rear of the bottom housing 15. Multiple connector holes 15c may be present, and these holes 15c can be arranged to mate corresponding positions of multiple connectors 1300. For example, the connector holes 15c may have the form of holes drilled through the bottom housing 15 in the front-rear direction X.

[0231] For example, connector 1300 may be mounted on substrate body 1210 as a separate part from substrate body 1210. Alternatively, connector 1300 may be integrally formed with substrate body 1210.

[0232] For example, connector 1300 may be formed having a long side 1301 and a short side 1302 shorter than the long side 1301. For example, the long side 1301 and the short side 1302 of connector 1300 may be perpendicular to each other, but are not limited thereto.

[0233] In this configuration, the long side 1301 of connector 1300 can be parallel to the first direction Z. Specifically, connector 1300 can be arranged such that the long side 1301 is parallel to the first direction Z. In other words, connector 1300 can be arranged to be longer in the first direction Z than in the second direction Y, and connector 1300 can extend elongatedly in the first direction Z. Connector 1300 can be arranged such that the long side 1301 is parallel to the first direction Z, i.e., parallel to the length direction of substrate body 1210. Connector 1300 can be arranged such that the long side 1301 is substantially perpendicular to the second direction, i.e., substantially perpendicular to the direction along which substrate strip 1220 extends. Connector 1300 can be arranged such that the long side 1301 is parallel to the first direction Z, i.e., parallel to the direction along which the plurality of substrate strips 1220 are arranged.

[0234] Unlike the arrangement shown in Figure 7, assuming the short side 1302 of connector 1300 is parallel to the first direction Z, connector 1300 can be arranged such that the long side 1301 is parallel to the second direction Y. Therefore, the substrate body 1210 on which connector 1300 is mounted may need to be longer in the second direction Y than in the case shown in Figure 7. In this case, more material may be required to produce the substrate body 1210, potentially increasing production costs.

[0235] On the other hand, as shown in Figure 7, since the long side 1301 of the connector 1300 is parallel to the first direction Z, less material is needed to produce the substrate body 1210, and production costs can be saved.

[0236] For example, the wire C connected to the driver board 70 can be arranged to be electrically connected to the connector 1300 via a connection terminal 1300a provided on the long side 1301 of the connector 1300. Furthermore, for example, the power supply line 1230 of the light source substrate 1200 can be arranged to be electrically connected to the connector 1300 via a connection terminal 1300a provided on the long side 1301 of the connector 1300.

[0237] In some embodiments, in each of the plurality of light source modules 1000, the connector 1300 may be arranged such that the connection terminal 1300a is positioned in the same direction relative to the light source substrate 1200.

[0238] For example, referring to Figures 8 and 9, in each of the plurality of light source modules 1000, the connector 1300 can be arranged such that the connection terminal 1300a points in the direction along which the substrate strip 1220 is positioned relative to the substrate body 1210.

[0239] Therefore, multiple light source modules 1000 can all have the same structure, thereby saving on component production costs and improving product manufacturing efficiency.

[0240] Figure 8 is a front view of the light source substrate and bottom housing of a display device according to an embodiment of the present disclosure. Figure 9 is a rear view of the PBA and bottom housing of a display device according to an embodiment of the present disclosure.

[0241] Referring to Figures 8 and 9, the display device 1 may include a plurality of light source substrates 1200 and a driver board 70. The plurality of light source substrates 1200 have a plurality of light sources 1100 mounted on them. The driver board 70 is arranged to control the operation of each of the plurality of light sources 1100. For example, as shown in Figures 8 and 9, the driver board 70 may be positioned at approximately the center of the display device 1 in the second direction Y. In other words, the driver board 70 may be positioned at approximately the center of the bottom housing 15.

[0242] The driver board 70 can be electrically connected to each of the plurality of light source substrates 1200 to control the operation of the light source 1100 mounted on that light source substrate. Each of the plurality of light source substrates 1200 can be electrically connected to the driver board 70 via a wire C. Multiple wires C can be provided, such that each of the plurality of light source substrates 1200 is connected to the driver board 70.

[0243] The driver board 70 may include multiple connection ports arranged to allow multiple wires C to be connected to the driver board 70. A single wire C may connect to a connection port on the driver board 70 and to a connector 1300 on one of the multiple light source substrates 1200. Thus, the driver board 70 and each of the multiple light source substrates 1200 can be electrically connected via the wires C, and drive current from the driver board 70 can be transmitted to each light source substrate 1200 via the wires C. The wires C can extend from the connection port of the driver board 70 to the connector 1300 on the light source substrate 1200.

[0244] As described above, connector 1300 can be disposed on substrate body 1210 of light source substrate 1200. Specifically, connector 1300 can be mounted on the rear surface of substrate body 1210. The rear surface of substrate body 1210 refers to the surface of substrate body 1210 that faces the bottom housing, opposite to the front surface of substrate body 1210 facing the display panel 20. As shown in FIG7, connector 1300 can be disposed through connector hole 15c of bottom housing 15 to connect to wire C disposed behind bottom housing 15. Alternatively, connector 1300 may not pass through bottom housing 15; instead, wire C may be drilled through bottom housing 15 to access connector 1300 from the front of bottom housing 15.

[0245] In this case, the position of connector 1300 can vary depending on the direction along which the light source substrate 1200 is mounted on the bottom housing 15.

[0246] As described above, the light source substrate 1200 can be arranged such that the substrate body 1210 is located to the left (in the -Y direction) of the substrate strip 1220 (e.g., the four light source substrates 1200 in the right two columns in FIG. 8). In this case, the connector 1300 can be located to the left of the substrate strip 1220. In this case, since the substrate body 1210 has a short width in the horizontal direction Y, but the substrate strip 1220 extends in the horizontal direction Y, the connector 1300 can be offset to the left on the light source substrate 1200.

[0247] Alternatively, the light source substrate 1200 can be arranged such that the substrate body 1210 is located to the right (in the +Y direction) of the substrate strip 1220 (e.g., the four light source substrates 1200 in the left two columns of FIG. 8). In this case, the connector 1300 can be located to the right of the substrate strip 1220. In this case, since the substrate body 1210 has a short width in the horizontal direction Y, but the substrate strip 1220 extends in the horizontal direction Y, the connector 1300 can be offset to the right on the light source substrate 1200.

[0248] Thus, depending on the orientation of the substrate body 1210 relative to the substrate strip 1220, the orientation of the connector 1300 arranged based on the center portion of the light source substrate 1200 can be changed, which can lead to a change in the spacing between the driver board 70 and the connector 1300. In other words, depending on the direction along which the light source substrate 1200 is mounted, the extension length of the wire C connecting the connection port of the driver board 70 to the connector 1300 can be changed.

[0249] When the extension length of wire C increases with the increase in the distance between the drive board 70 and the connector 1300, noise may increase due to the current flowing in wire C, which may lead to product quality degradation. Furthermore, when the extension length of wire C increases, more design factors may need to be considered in arranging wire C to avoid interfering with other parts of the display device 1, making product design less efficient and potentially reducing production efficiency. Unnecessarily increasing the extension length of wire C may also increase production costs.

[0250] Therefore, in some embodiments, at least some of the plurality of light source substrates 1200 may be arranged such that the substrate body 1210 is further away from the boundaries 15A and 15B of the bottom housing 15 than the plurality of substrate strips 1220. Furthermore, at least some of the plurality of light source substrates 1200 may be arranged such that the substrate body 1210 is closer to the drive board 70 than the plurality of substrate strips 1220.

[0251] As shown in the figure, the bottom housing 15 may include a horizontal boundary 15A extending in a second direction Y (i.e., the horizontal direction of the display device 1) and a vertical boundary 15B extending in a first direction Z (i.e., the vertical direction of the display device 1). The horizontal boundaries 15A of the bottom housing 15 may be provided as a pair. The vertical boundaries 15B of the bottom housing 15 may be provided as a pair. For example, the bottom housing 15 may have a substantially rectangular shape, having a pair of horizontal boundaries 15A and a pair of vertical boundaries 15B.

[0252] Specifically, at least some of the plurality of light source substrates 1200 can be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. The boundaries 15A and 15B of the bottom housing 15 may include a pair of horizontal boundaries 15A extending in the horizontal direction Y and a pair of vertical boundaries 15B extending in the vertical direction Z, and at least some of the plurality of light source substrates 1200 can be arranged such that the spacing between the substrate body 1210 and the vertical boundary 15B is longer than the spacing between the plurality of substrate strips 1220 and the vertical boundary 15B. That is, some of the light source substrates 1200A of the plurality of light source substrates 1200 arranged adjacent to the vertical boundary 15B of the bottom housing 15 can be arranged such that the substrate body 1210 is further away from the vertical boundary 15B of the bottom housing 15 in the second direction Y (i.e., the horizontal direction) than the plurality of substrate strips 1220.

[0253] In other words, at least some of the multiple light source substrates 1200 can be arranged such that the substrate body 1210 is further away from the boundary of the display housing in the second direction Y than the multiple substrate strips 1220.

[0254] In other words, at least some of the multiple light source substrates 1200 can be arranged such that the substrate body 1210 is closer to the drive plate 70 than the multiple substrate strips 1220. At least some of the multiple light source substrates 1200 can have multiple substrate strips 1220 extending from the substrate body 1210 to become farther away from the drive plate 70 in the second direction Y.

[0255] Specifically, on one of the plurality of light source substrates 1200 adjacent to one of the vertical boundaries 15B (e.g., the left boundary in the -Y direction of FIG. 8), each of the plurality of substrate strips 1220 can extend from the substrate body 1210 toward that one boundary 15B (e.g., the left boundary in FIG. 8). Symmetrically, on another of the plurality of light source substrates 1200 adjacent to the other vertical boundary 15B (e.g., the right boundary in the +Y direction of FIG. 8), each of the plurality of substrate strips 1220 can extend from the substrate body 1210 toward that other boundary 15B (e.g., the right boundary in FIG. 8).

[0256] In other words, on one of the plurality of light source substrates 1200 adjacent to one of the vertical boundaries 15B (e.g., the left boundary in the -Y direction of FIG. 8), each of the plurality of substrate strips 1220 can extend from the substrate body 1210 to become remote from the drive plate 70. Symmetrically, on one of the plurality of light source substrates 1200 adjacent to the other vertical boundary 15B (e.g., the right boundary in the +Y direction of FIG. 8), each of the plurality of substrate strips 1220 can extend from the substrate body 1210 to become remote from the drive plate 70.

[0257] In this case, assuming that a light source substrate 1200 that is closer to one of the vertical boundaries 15B (i.e., the left boundary in the -Y direction of FIG8) is one of the light source substrates 1200A among the plurality of light source substrates 1200 that is closest to the vertical boundary 15B of the bottom housing 15, and assuming that another light source substrate 1200 that is closer to the other vertical boundary 15B (e.g., the right boundary in the +Y direction of FIG8) is another light source substrate 1200A among the plurality of light source substrates 1200 that is closest to the vertical boundary 15B of the bottom housing 15, then the spacing between the one vertical boundary 15B and the one light source substrate 1200A in the second direction Y can correspond to the spacing between the other vertical boundary 15B and the other light source substrate 1200A in the second direction Y.

[0258] Alternatively, assuming that a light source substrate 1200 more adjacent to one of the vertical boundaries 15B (i.e., the left boundary in the -Y direction of FIG8) is one of the light source substrates 1200B that are second adjacent to the vertical boundary 15B of the bottom housing 15 among the plurality of light source substrates 1200B, and assuming that another light source substrate 1200 more adjacent to the other vertical boundary 15B (e.g., the right boundary in the +Y direction of FIG8) among the pair of vertical boundaries 15B is another light source substrate 1200B that is second adjacent to the vertical boundary 15B of the bottom housing 15 among the plurality of light source substrates 1200B, then the spacing between the one vertical boundary 15B and the one light source substrate 1200B in the second direction Y can correspond to the spacing between the other vertical boundary 15B and the other light source substrate 1200B in the second direction Y.

[0259] Therefore, at least some of the multiple light source substrates 1200 can be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the horizontal direction Y, and the substrate body 1210 is closer to the drive plate 70 in the horizontal direction Y than the multiple substrate strips 1220.

[0260] In other words, at least some of the multiple light source substrates 1200 can be arranged such that the substrate body 1210 is further away from the short side of the bottom housing 15 than the multiple substrate strips 1220.

[0261] More specifically, some of the multiple light source substrates 1200A arranged adjacent to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y can be arranged such that the substrate body 1210 is further away from the boundaries 15A or 15B of the bottom housing 15 in the second direction Y than the multiple substrate strips 1220. Among the multiple light source substrates 1200, the light source substrate 1200A arranged closest to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y is referred to as the first light source substrate 1200A. The first light source substrate 1200A can be arranged to be closest to the boundary of the display housing in the second direction Y.

[0262] The vertical boundaries 15B of the bottom housing 15 include a pair of vertical boundaries 15B facing each other, therefore the first light source substrate 1200A may include at least one pair of first light source substrates 1200A. In other words, the display device 1 may include a pair of first light source substrates 1200A arranged in the second direction Y, which are closest to the boundaries 15A and 15B of the bottom housing 15 among a plurality of light source substrates 1200. The pair of first light source substrates 1200A may be arranged to face each other in the second direction Y.

[0263] The arrangement of a pair of first light source substrates 1200A does not precisely mean that only two of the plurality of light source substrates 1200A are closest to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y. For example, as shown in FIG8, the plurality of light source substrates 1200 can be arranged in a plurality of rows and a plurality of columns. The plurality of rows can extend in the second direction Y and can be arranged along the first direction Z. The plurality of columns can extend in the first direction Z and can be arranged along the second direction Y. The light source substrates 1200 included in one of the plurality of rows can be arranged along the second direction Y, and the light source substrates 1200 included in one of the plurality of columns can be arranged along the first direction Z. In particular, on the light source substrates 1200 included in a column, a plurality of substrate strips 1220 can be arranged along the first direction Z, and each substrate body 1210 can be arranged along the first direction Z. In this case, a pair of first light source substrates 1200A can be included in each row. Each of a pair of columns closest to the vertical boundary 15B of the bottom housing 15 in the second direction Y may include as many first light source substrates 1200A as rows. On the first light source substrates 1200A included in a column, corresponding substrate strips 1220 may be arranged along the first direction Z, and corresponding substrate bodies 1210 may be arranged along the first direction Z. For example, in some embodiments as shown in FIG8, the display device 1 may include a total of four first light source substrates 1200A.

[0264] Each of the pair of first light source substrates 1200A can be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 than the plurality of substrate strips 1220 in the second direction Y. In other words, each of the pair of first light source substrates 1200A can be arranged such that the substrate body 1210 is closer to the drive board 70 than the plurality of substrate strips 1220. On each of the pair of first light source substrates 1200A, the plurality of substrate strips 1220 can extend from the substrate body 1210 toward the boundary 15A or 15B of the bottom housing 15 in the second direction Y.

[0265] For example, one of the first light source substrates 1200A arranged on the left (in the -Y direction) may have a substrate body 1210 arranged further to the right (in the +Y direction) than the plurality of substrate strips 1220, and the plurality of substrate strips 1220 extend to the left from the substrate body 1210. The other first light source substrate 1200A arranged on the right (in the +Y direction) may have a substrate body 1210 arranged further to the left (in the -Y direction) than the plurality of substrate strips 1220, and the plurality of substrate strips 1220 extend to the right from the substrate body 1210.

[0266] For example, when the pair of vertical boundaries 15B of the bottom housing 15 includes a first vertical boundary (a vertical boundary 15B arranged on the left side of FIG. 8 (in the -Y direction)) and a second vertical boundary (a vertical boundary 15B arranged on the right side of FIG. 8 (in the +Y direction)) facing each other, the plurality of light source substrates 1200 may include a pair of first light source substrates 1200A arranged most adjacent to the pair of vertical boundaries 15B. One of the pair of first light source substrates 1200A arranged closer to the first vertical boundary than to the second vertical boundary (i.e., the first light source substrate 1200A arranged on the left side of FIG. 8 (in the -Y direction)) may be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the first vertical boundary (i.e., toward the left side of FIG. 8 (in the -Y direction)). Symmetrically, the other first light source substrate of the pair of first light source substrates 1200A, which is arranged closer to the second vertical boundary than to the first vertical boundary (i.e., the first light source substrate 1200A arranged on the right side of FIG8 (in the +Y direction)), can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the second vertical boundary (i.e., toward the right side of FIG8 (in the +Y direction)).

[0267] In this case, for example, the spacing between the first vertical boundary and the first light source substrate 1200A adjacent to the first vertical boundary can substantially correspond to the spacing between the second vertical boundary and another first light source substrate 1200A adjacent to the second vertical boundary.

[0268] Using this structure, the first light source substrate 1200A can be arranged such that the substrate body 1210 is adjacent to the driving board 70, and the length of the wire C connecting the driving board 70 to the connector 1300 can be shortened. Therefore, the shorter wire C can lead to savings in product manufacturing costs, reduce noise from the current flowing in the wire C, and prevent the wire C from being interfered with by other parts of the display device 1.

[0269] Furthermore, when the connector 1300 disposed on the first light source substrate 1200A is arranged near the boundary 15A or 15B of the bottom housing 15, the wire C may be interfered with by the boundary 15A or 15B of the bottom housing 15 at a position adjacent to the connector 1300, making it difficult to connect the wire C to the connector 1300. In some embodiments, using the above structure, the connector 1300 can be arranged further away from the boundary 15A or 15B of the bottom housing 15, and the interference of the wire C by the boundary 15A or 15B of the bottom housing 15 can be prevented.

[0270] Furthermore, some other light source substrates 1200B among the plurality of light source substrates 1200, which are arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the first light source substrate 1200A, can be arranged such that the substrate body 1210 is arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the plurality of substrate strips 1220. These other light source substrates 1200B among the plurality of light source substrates 1200, which are arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the first light source substrate 1200A, are referred to as second light source substrates 1200B. The second light source substrate 1200B can be positioned inside the boundary of the bottom housing 15 further away from the first light source substrate 1200A in the second direction Y.

[0271] The second light source substrate 1200B can be arranged such that the distance between the substrate body 1210 and the vertical boundary 15B is longer than the distance between the plurality of substrate strips 1220 and the vertical boundary 15B. In other words, the second light source substrate 1200B can be arranged such that the substrate body 1210 is further away from the boundary of the display housing in the second direction Y than the plurality of substrate strips 1220.

[0272] On the second light source substrate 1200B, a plurality of substrate strips 1220 may each extend from the substrate body 1210 toward the boundary 15A or 15B of the bottom housing 15 in a second direction Y. In other words, the second light source substrate 1200B may have a plurality of substrate strips 1220 extending from the substrate body 1210 in a direction that becomes farther away from the drive plate 70.

[0273] The second light source substrate 1200B may include at least one pair of second light source substrates 1200B. Specifically, the display device 1 may include a pair of second light source substrates 1200B that are further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the first light source substrate 1200A. The pair of second light source substrates 1200B may be arranged to face each other in the second direction Y.

[0274] A pair of second light source substrates 1200B can be arranged between a pair of first light source substrates 1200B. The pair of second light source substrates 1200B can be arranged parallel to the first light source substrates 1200B in the second direction Y.

[0275] For example, as shown in FIG8, multiple light source substrates 1200 can be arranged in multiple rows and multiple columns, and each row may include a pair of second light source substrates 1200B. On the second light source substrates 1200B included in a column, corresponding substrate strips 1220 may be arranged along a first direction Z, and corresponding substrate bodies 1210 may be arranged along the first direction Z. For example, in the embodiment of FIG8, the display device 1 may include a total of four second light source substrates 1200B.

[0276] Each of the pair of second light source substrates 1200B can be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. In other words, on each of the pair of second light source substrates 1200B, the plurality of substrate strips 1220 can extend from the substrate body 1210 toward the boundary 15A or 15B of the bottom housing 15 in the second direction Y. Each of the pair of second light source substrates 1200B can have a plurality of substrate strips 1220 extending from the substrate body 1210 in the second direction Y to be further away from the drive board 70. Each of the pair of second light source substrates 1200B can have a plurality of substrate strips 1220 extending from the substrate body 1210 toward a more adjacent first light source substrate in the pair of first light source substrates 1200A.

[0277] For example, one of the pair of second light source substrates 1200B arranged on the left (in the -Y direction) may have a substrate body 1210 arranged further to the right (in the +Y direction) than the plurality of substrate strips 1220, and the plurality of substrate strips 1220 extend to the left from the substrate body 1210. The other of the pair of second light source substrates 1200B arranged on the right (in the +Y direction) may have a substrate body 1210 arranged further to the left (in the -Y direction) than the plurality of substrate strips 1220, and the plurality of substrate strips 1220 extend to the right from the substrate body 1210.

[0278] For example, when the pair of vertical boundaries 15B of the bottom housing 15 includes a first vertical boundary (a vertical boundary 15B arranged on the left side of FIG. 8 (in the -Y direction)) and a second vertical boundary (a vertical boundary 15B arranged on the right side of FIG. 8 (in the +Y direction)) facing each other, the plurality of light source substrates 1200 may include a pair of second light source substrates 1200B arranged between the pair of first light source substrates 1200A. One of the pair of second light source substrates 1200B arranged closer to the first vertical boundary than to the first vertical boundary (i.e., the second light source substrate 1200B arranged on the left side of FIG. 8 (in the -Y direction)) may be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the first vertical boundary (i.e., toward the left side of FIG. 8 (in the -Y direction)). Symmetrically, the other second light source substrate of the pair of second light source substrates 1200B, which is arranged closer to the second vertical boundary than to the first vertical boundary (i.e., the second light source substrate 1200B arranged on the right side of FIG8 (in the +Y direction)), can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the second vertical boundary (i.e., toward the right side of FIG8 (in the +Y direction)).

[0279] In this case, for example, the spacing between the first vertical boundary and the second light source substrate 1200B adjacent to the first vertical boundary can substantially correspond to the spacing between the second vertical boundary and another second light source substrate 1200B adjacent to the second vertical boundary.

[0280] Using this structure, the second light source substrate 1200B can be arranged such that the substrate body 1210 is adjacent to the drive board 70, and the length of the wire C connecting the drive board 70 to the connector 1300 can be shortened. Therefore, the shorter wire C can lead to savings in product manufacturing costs, reduce noise from the current flowing in the wire C, and prevent the wire C from being interfered with by other parts of the display device 1.

[0281] In a plurality of light source substrates 1200, each of a pair of second light source substrates 1200B can be arranged to have the shortest possible spacing between the substrate body 1210 and the driving plate 70. In other words, the spacing between the substrate body 1210 and the driving plate 70 of a pair of second light source substrates 1200B can be shorter than the spacing between the substrate body 1210 and the driving plate 70 of a pair of first light source substrates 1200A.

[0282] For example, a pair of second light source substrates 1200B can be arranged adjacent to the central portion of the bottom housing in the second direction Y. The pair of second light source substrates 1200B can be arranged symmetrically based on a centerline passing through the center of the bottom housing 15 in the first direction Z. In this case, the substrate bodies of the pair of second light source substrates 1200B can be arranged adjacent to each other in the second direction Y.

[0283] As described above, the plurality of first light source substrates 1200A and the plurality of second light source substrates 1200B can each be configured as light source substrates 1200 having the same structure. Referring to FIG8, one of the plurality of light source substrates 1200 located on the right side (in the +Y direction) of the display device 1 and one of the plurality of light source substrates 1200 located on the left side (in the -Y direction) of the display device 1 can be arranged to have opposite vertical and horizontal directions (i.e., rotated 180 degrees relative to each other on the X-axis).

[0284] The bottom housing 15 may include a protrusion 15d projecting from the rear surface of the bottom housing 15. The protrusion 15d may include a portion that projects rearward further than other portions of the bottom housing 15. For example, the protrusion 15d may be formed to enhance the rigidity of the bottom housing 15. Specifically, the protrusion 15d may be arranged in a portion of the bottom housing 15 where the bottom housing 15 will be attached to other portions of the display device 1, thereby enhancing the rigidity of the portion to be attached. For example, the bottom housing 15 may include multiple protrusions 15d.

[0285] In this situation, when the substrate body 1210 of each of the multiple light source substrates 1200 is located in front of the protrusion 15d, it may be difficult to connect the wire C to the connector 1300. This is because the part of the wire C that connects to the connector 1300 may be interfered with by the protrusion 15d, or the connector 1300 may not be able to pass through the protrusion 15d.

[0286] Therefore, each of the plurality of light source substrates 1200 can be arranged such that the connector 1300 passes through a portion of the bottom housing 15 spaced apart from the plurality of protrusions 15d. Specifically, each of the plurality of light source substrates 1200 can be arranged such that: the substrate body 1210 is disposed in front of the portion of the bottom housing 15 excluding the protrusions 15d (in the +X direction), and the connector 1300 is connected to the wire C by passing through this portion of the bottom housing 15 excluding the protrusions 15d.

[0287] For example, when a portion of the protrusion 15d arranged adjacent to the boundary 15A or 15B of the bottom housing 15 is referred to as the first protrusion 15da, the connector 1300 arranged on the substrate body 1210 of each of the plurality of first light source substrates 1200A can be arranged to pass through a portion of the bottom housing 15 spaced apart from the first protrusion 15da. This layout and structure can be implemented because the first light source substrates 1200A are arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0288] Alternatively, for example, when another portion of the protrusion 15d arranged on the bottom housing 15, which is arranged to be further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the first protrusion 15da, is referred to as the second protrusion 15db, the connector 1300 arranged on the substrate body 1210 of each of the plurality of first light source substrates 1200A can be arranged to pass through the portion of the bottom housing 15 spaced apart from the second protrusion 15db.

[0289] For example, unlike that shown in Figure 1, when the display device 1 is a wall-mounted type display device that is mounted on a wall via a wall-mounted bracket, the second protrusion 15d may include a portion in which the wall-mounted bracket is mounted.

[0290] The display device 1 in Figures 8 and 9 can have a screen 12 with a diagonal length of 65 inches, but the length is not limited to this.

[0291] Although the display device 1 is illustrated in FIG. 8 as including eight light source modules 1000, the number of light source modules 1000 included in the display device 1 according to the present disclosure is not limited to the number shown in FIG. 8. For example, the display device 1 may include more or fewer light source modules 1000 than those shown in FIG. 8.

[0292] An embodiment in which the display device 1 has a screen 12 of a different size and a different number of light source modules 1000 than the embodiments shown in Figures 8 and 9 will now be described with reference to Figures 10 to 15.

[0293] Figure 10 is a front view of the light source substrate and bottom housing of a display device according to some embodiments of the present disclosure. Figure 11 is a rear view of the PBA and bottom housing of a display device according to some embodiments of the present disclosure.

[0294] Referring to Figures 10 and 11, when describing the structure of the display device 2, components that are repeated with components of the display device 1 have the same reference numerals as those in the embodiments of Figures 1 to 9, and their descriptions will not be repeated.

[0295] Referring to Figures 10 and 11, the display device 2 may include a plurality of light source substrates 1200. Some of the plurality of light source substrates 1200A arranged adjacent to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y may be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0296] Specifically, the display device 2 may include a pair of first light source substrates 1200A, which are closest to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y. The pair of first light source substrates 1200A may be arranged to face each other in the second direction Y. In this case, each of the pair of first light source substrates 1200A may be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. In other words, on each of the pair of first light source substrates 1200A, the plurality of substrate strips 1220 may extend from the substrate body 1210 toward the boundary 15A or 15B of the bottom housing 15 in the second direction Y.

[0297] As shown in FIG. 10, a row may include a pair of first light source substrates 1200A. Each of a pair of columns in the second direction Y, closest to the vertical boundary 15B of the bottom housing 15, may include the same number of first light source substrates 1200A as the row. For example, in the embodiment of FIG. 10, the display device 2 may include a total of four first light source substrates 1200A.

[0298] The display device 2 may include a second light source substrate 1200B, which is arranged in the second direction Y to be further away from the boundary 15A or 15B of the bottom housing 15 than a pair of first light source substrates 1200A. The second light source substrate 1200B may be positioned inside the boundary of the bottom housing 15 further away from the first light source substrates 1200A in the second direction Y. The distance between the second light source substrate 1200B and the driving board 70 in the second direction Y may be shorter than the distance between the first light source substrates 1200A and the driving board 70 in the second direction Y. The second light source substrate 1200B may be arranged between a pair of first light source substrates 1200A. The second light source substrate 1200B may be arranged parallel to the first light source substrates 1200A in the second direction Y.

[0299] For example, the second light source substrate 1200B can be arranged in the central portion of the bottom housing in the second direction Y. The second light source substrate 1200B can be arranged such that the distance to one of the vertical boundaries 15B is substantially equal to the distance to the other vertical boundary 15B in the pair of vertical boundaries 15B.

[0300] As shown in FIG10, the number of second light source substrates 1200B included in a row among the plurality of light source substrates 1200 can be set to an odd number. For example, in the embodiment of FIG10, the display device 2 may include a total of two second light source substrates 1200B.

[0301] As shown in FIG10, the second light source substrate 1200B can be arranged such that the substrate body 1210 is adjacent to the substrate body 1220 of one of the first light source substrates 1200A in a pair of first light source substrates 1200A. In addition, the second light source substrate 1200B may have a plurality of substrate strips 1220 extending in the second direction Y from the substrate body 1210 toward the substrate body 1210 of the other first light source substrate 1200A in the pair of first light source substrates 1200A.

[0302] For example, the second light source substrate 1200B can be arranged such that the substrate body 1210 is adjacent to a first vertical boundary (e.g., the left boundary (in the -Y direction) of a pair of vertical boundaries 15B of the bottom housing 15). The second light source substrate 1200B may have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the second vertical boundary (e.g., the right boundary (in the +Y direction) of Figure 10).

[0303] In addition to the driver board 70, the display device 2 may also include a first board 50 and a second board 60 configured as a PBA. The first board 50 and the second board 60 may each be electrically connected to the driver board 70. The first board 50 and the second board 60 may each include a plurality of connection ports arranged thereon for connecting wires or electrical components.

[0304] For example, the first plate 50, the drive plate 70, and the second plate 60 can be arranged substantially along the second direction Y. However, as shown in Figures 10 and 11, the first plate 50, the drive plate 70, and the second plate 60 can be arranged to be imperfectly parallel to each other along the second direction Y.

[0305] The second light source substrate 1200B may have a substrate body 1210 arranged closer to the second plate than closer to the first plate 50. In other words, the distance between the substrate body 1210 of the second light source substrate 1200B and the second plate 60 in the second direction Y may be shorter than the distance between the substrate body 1210 of the second light source substrate 1200B and the first plate 50 in the second direction Y.

[0306] In this configuration, for example, the first board 50 may have more connection ports than the second board 60. Because the first board 50 has more connection ports than the second board 60, there can be more wires or electronic components connected to the connection ports of the first board 50 than to the connection ports of the second board 60. Therefore, the second light source substrate 1200B can be arranged such that the substrate body 1210 is closer to the second board 60 in the second direction Y than to the first board 50, in order to reduce interference between the wires C connected to the connector 1300 and the portions connected to the connection ports of the other boards 50 and 60.

[0307] For example, the first board 50 can be the motherboard, and the second board 60 can be the power supply board.

[0308] For example, the display device 2 of Figures 10 and 11 may have a screen 12 with a diagonal length of 55 inches, but the length is not limited to this.

[0309] Figure 12 is a front view of the light source substrate and bottom housing of a display device according to some embodiments of the present disclosure. Figure 13 is a rear view of the PBA and bottom housing of a display device according to some embodiments of the present disclosure.

[0310] Referring to Figures 12 and 13, when describing the structure of the display device 3, components that overlap with components of the display device 1 have the same reference numerals as those in the embodiments of Figures 1 to 9, and their descriptions will not be repeated.

[0311] Referring to Figures 12 and 13, the display device 3 may include a plurality of light source substrates 1200. Some of the plurality of light source substrates 1200A arranged adjacent to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y may be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0312] Specifically, the display device 3 may include a pair of first light source substrates 1200A, which are closest to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y. The pair of first light source substrates 1200A may be arranged to face each other in the second direction Y. In this case, each of the pair of first light source substrates 1200A may be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. In other words, on each of the pair of first light source substrates 1200A, the plurality of substrate strips 1220 may extend from the substrate body 1210 toward the boundary 15A or 15B of the bottom housing 15 in the second direction Y. The pair of first light source substrates 1200A may have a plurality of substrate strips 1220 extending from the substrate body 1210 in a direction away from the drive plate 70.

[0313] As shown in FIG12, a row may include a pair of first light source substrates 1200A. Each of a pair of columns in the second direction Y, closest to the vertical boundary 15B of the bottom housing 15, may include the same number of first light source substrates 1200A as the row. For example, in the embodiment of FIG12, the display device 3 may include a total of four first light source substrates 1200A.

[0314] Some other light source substrates 1200B, which are arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the first light source substrate 1200A, may have a substrate body 1210 arranged closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the multiple substrate strips 1220.

[0315] Specifically, the display device 3 may include a pair of second light source substrates 1200B disposed between a pair of first light source substrates 1200A. The pair of second light source substrates 1200B may be arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the pair of first light source substrates 1200A. The pair of second light source substrates 1200B may be positioned closer to the inner side of the bottom housing 15 in the second direction Y than the pair of first light source substrates 1200A. The pair of second light source substrates 1200B may be arranged facing each other in the second direction Y.

[0316] As shown in FIG12, a row may include a pair of second light source substrates 1200B. For example, in the embodiment of FIG12, the display device 3 may include a total of four second light source substrates 1200B.

[0317] In this configuration, each of the pair of second light source substrates 1200B can be arranged such that the substrate body 1210 is closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. In other words, each of the pair of second light source substrates 1200B can have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the more distant of the pair of first light source substrates 1200A. In other words, each of the pair of second light source substrates 1200B can have a plurality of substrate strips 1220 extending from the substrate body 1210 in a direction closer to the drive plate 70.

[0318] For example, one of a pair of second light source substrates 1200B, arranged closer to the first vertical boundary (vertical boundary 15B arranged on the left side of FIG. 12 (in the -Y direction)) rather than closer to the second vertical boundary (vertical boundary 15B arranged on the right side of FIG. 12 (in the +Y direction)), can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the second vertical boundary (i.e., toward the right side of FIG. 12 (in the +Y direction)). Symmetrically, the other second light source substrate 1200B in the pair of second light source substrates 1200B, arranged closer to the second vertical boundary rather than closer to the first vertical boundary (i.e., the second light source substrate 1200B arranged on the right side of FIG. 12 (in the +Y direction)), can have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the first vertical boundary (i.e., toward the left side of FIG. 12 (in the -Y direction)).

[0319] In this case, for example, the spacing between the first vertical boundary and the second light source substrate 1200B adjacent to the first vertical boundary can substantially correspond to the spacing between the second vertical boundary and another second light source substrate 1200B adjacent to the second vertical boundary.

[0320] As shown in Figure 13, the bottom housing 15 may include a plurality of protrusions 15d projecting rearward (in the -X direction) from the rear surface of the bottom housing 15. The structure and characteristics of the protrusions 15d of the bottom housing 15 may correspond to the protrusions 15d shown in Figure 9. The bottom housing 15 may include a first protrusion 15da and a second protrusion 15db. In particular, the second protrusion 15db of the bottom housing 15 may be arranged to be coupled to a wall-mounted bracket WM.

[0321] Each of the plurality of light source substrates 1200 can be arranged such that the connector 1300 passes through a portion of the bottom housing 15 spaced apart from the plurality of protrusions 15d. Specifically, each of the plurality of light source substrates 1200 can be arranged such that: the substrate body 1210 is disposed in front of the portion of the bottom housing 15 excluding the protrusions 15d (in the +X direction), and the connector 1300 is connected to the wire C by passing through the portion of the bottom housing 15 excluding the protrusions 15d.

[0322] For example, the connector 1300 on the substrate body 1210 of each of the plurality of first light source substrates 1200A can be arranged to pass through a portion of the bottom housing 15 spaced apart from the first protrusion 15da. Such a layout and structure can be implemented because the substrate body 1210 of the first light source substrate 1200A is positioned further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0323] Furthermore, for example, the connector 1300 on the substrate body 1210 of each of the plurality of second light source substrates 1200B can be arranged to pass through a portion of the bottom housing 15 spaced apart from the second protrusion 15db. This layout and structure can be implemented because the substrate body 1210 of the second light source substrate 1200B is positioned closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. With this structure, the connector 1300 of the second light source substrate 1200B and the wire C connected to the connector 1300 are not only unaffected by the second protrusion 15db, but also unaffected by the wall-mounted bracket WM.

[0324] The display device 3 may include a third light source substrate 1200C, which is arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than a pair of second light source substrates 1200B. The third light source substrate 1200C may be positioned inside the boundary of the bottom housing 15 further away from the second light source substrates 1200B in the second direction Y. The distance between the third light source substrate 1200C and the driving board 70 in the second direction Y may be shorter than the distance between the second light source substrates 1200B and the driving board 70 in the second direction Y. The third light source substrate 1200C may be arranged between a pair of second light source substrates 1200B. The third light source substrate 1200C may be arranged parallel to a pair of first light source substrates 1200A and a pair of second light source substrates 1200B in the second direction Y.

[0325] For example, the third light source substrate 1200C can be disposed at the center portion of the bottom housing in the second direction Y. The third light source substrate 1200C can be arranged such that the spacing to one of the vertical boundaries 15B is substantially equal to the spacing to the other vertical boundary 15B.

[0326] As shown in FIG12, the number of third light source substrates 1200C included in a row can be odd. For example, in the embodiment of FIG12, the display device 3 may include a total of two third light source substrates 1200C.

[0327] As shown in Figure 12, the third light source substrate 1200C can be arranged such that the substrate body 1210 is adjacent to the substrate body 1220 of one of the second light source substrates 1200B, and a plurality of substrate strips 1220 extend from the substrate body 1220 toward the substrate body 1210 of the other second light source substrate 1200B in the second direction Y.

[0328] For example, the second light source substrate 1200B can be arranged such that the substrate body 1210 is adjacent to the second vertical boundary (e.g., the right boundary (in the +Y direction) of a pair of vertical boundaries 15B of the bottom housing 15). The second light source substrate 1200B may have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the first vertical boundary (e.g., the left boundary (in the -Y direction) of FIG. 12).

[0329] For example, the display device 3 of Figures 12 and 13 may have a screen 12 with a diagonal length of 75 inches, but the length is not limited to this.

[0330] Figure 14 is a front view of the light source substrate and bottom housing of a display device according to some embodiments of the present disclosure. Figure 15 is a rear view of the printed circuit board assembly (PBA) and bottom housing of a display device according to some embodiments of the present disclosure.

[0331] Referring to Figures 14 and 15, when describing the structure of the display device 4, components that overlap with components of the display device 1 have the same reference numerals as those in the embodiments of Figures 1 to 9, and their descriptions will not be repeated.

[0332] Referring to Figures 14 and 15, the display device 4 may include a plurality of light source substrates 1200. Some of the plurality of light source substrates 1200A arranged adjacent to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y may be arranged such that the substrate body 1210 is further away from the boundaries 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0333] Specifically, the display device 4 may include a pair of first light source substrates 1200A, which are closest to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y. The pair of first light source substrates 1200A may be arranged to face each other in the second direction Y. In this case, each of the pair of first light source substrates 1200A may be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. In other words, on each of the pair of first light source substrates 1200A, the plurality of substrate strips 1220 may extend from the substrate body 1210 toward the boundary 15A or 15B of the bottom housing 15 in the second direction Y. The pair of first light source substrates 1200A may have a plurality of substrate strips 1220 extending from the substrate body 1210 in a direction away from the drive plate 70.

[0334] As shown in FIG. 14, a row may include a pair of first light source substrates 1200A. Each of a pair of columns in the second direction Y, closest to the vertical boundary 15B of the bottom housing 15, may include the same number of first light source substrates 1200A as the row. For example, in the embodiment of FIG. 14, the display device 4 may include a total of four first light source substrates 1200A.

[0335] Some other light source substrates 1200B among the plurality of light source substrates 1200, which are arranged to be farther away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the first light source substrate 1200A, may have a substrate body 1210 arranged to be closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y compared to the plurality of substrate strips 1220.

[0336] Specifically, the display device 4 may include a pair of second light source substrates 1200B disposed between a pair of first light source substrates 1200A. The pair of second light source substrates 1200B may be arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the pair of first light source substrates 1200A. The pair of second light source substrates 1200B may be positioned closer to the inner side of the bottom housing 15 in the second direction Y than the pair of first light source substrates 1200A. The pair of second light source substrates 1200A may be arranged facing each other in the second direction Y.

[0337] As shown in FIG14, a row may include a pair of second light source substrates 1200B. For example, in the embodiment of FIG14, the display device 4 may include a total of four second light source substrates 1200B.

[0338] In this configuration, each of the pair of second light source substrates 1200B can be arranged such that the substrate body 1210 is closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. In other words, each of the pair of second light source substrates 1200B can have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the more distant of the pair of first light source substrates 1200A. In other words, each of the pair of second light source substrates 1200B can have a plurality of substrate strips 1220 extending from the substrate body 1210 in a direction closer to the drive plate 70.

[0339] Each of the plurality of light source substrates 1200 can be arranged such that the connector 1300 passes through a portion of the bottom housing 15 spaced apart from a plurality of protrusions 15d of the bottom housing 15. Specifically, each of the plurality of light source substrates 1200 can be arranged such that the substrate body 1210 is positioned in front of (in the +X direction) the portion of the bottom housing 15 excluding the protrusions 15d, and the connector 1300 is connected to the wire C by passing through this portion of the bottom housing 15 excluding the protrusions 15d.

[0340] For example, the connector 1300 on the substrate body 1210 of each of the plurality of first light source substrates 1200A can be arranged to pass through a portion of the bottom housing 15 spaced apart from the first protrusion 15da. Such a layout and structure can be implemented because the substrate body 1210 of the first light source substrate 1200A is positioned further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0341] Furthermore, for example, the connector 1300 on the substrate body 1210 of each of the plurality of second light source substrates 1200B can be arranged to pass through a portion of the bottom housing 15 spaced apart from the second protrusion 15db. This layout and structure can be implemented because the substrate body 1210 of the second light source substrate 1200B is positioned closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. With this structure, the connector 1300 of the second light source substrate 1200B and the wire C connected to the connector 1300 are not only unaffected by the second protrusion 15db, but also unaffected by the wall-mounted bracket WM.

[0342] The display device 3 may include a pair of third light source substrates 1200C, which are arranged in the second direction Y to be further away from the boundary 15A or 15B of the bottom housing 15 than a pair of second light source substrates 1200B. The pair of third light source substrates 1200C may be positioned inside the boundary of the bottom housing 15 in the second direction Y than a pair of second light source substrates 1200B. The distance between each of the third light source substrates 1200C and the driving board 70 in the second direction Y may be shorter than the distance between each of the second light source substrates 1200B and the driving board 70 in the second direction Y. The pair of third light source substrates 1200C may be arranged between the pair of second light source substrates 1200B. The pair of third light source substrates 1200C may be arranged parallel to a pair of first light source substrates 1200A and a pair of second light source substrates 1200B in the second direction Y. The pair of third light source substrates 1200C may be arranged to face each other in the second direction Y.

[0343] As shown in FIG. 14, each row may include a pair of third light source substrates 1200C. On the third light source substrates 1200C included in a row, corresponding substrate strips 1220 may be arranged along a first direction Z, and corresponding substrate bodies 1210 may be arranged along the first direction Z. For example, in the embodiment of FIG. 14, the display device 4 may include a total of four third light source substrates 1200C.

[0344] Each of the pair of third light source substrates 1200C can be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220. In other words, on each of the pair of third light source substrates 1200C, the plurality of substrate strips 1220 can extend from the substrate body 1210 toward the boundary 15A or 15B of the bottom housing 15 in the second direction Y. Each of the pair of third light source substrates 1200C can have a plurality of substrate strips 1220 extending from the substrate body 1210 in the second direction Y to extend further away from the drive board 70. Each of the pair of third light source substrates 1200C can have a plurality of substrate strips 1220 extending from the substrate body 1210 toward a more adjacent second light source substrate in the pair of second light source substrates 1200B.

[0345] For example, one of the third light source substrates 1200C arranged on the left (in the -Y direction) may have a substrate body 1210 arranged further to the right (in the +Y direction) than the plurality of substrate strips 1220, and the plurality of substrate strips 1220 extend to the left from the substrate body 1210. The third light source substrate 1200C arranged on the right (in the +Y direction) may have a substrate body 1210 arranged further to the left (in the -Y direction) than the plurality of substrate strips 1220, and the plurality of substrate strips 1220 extend to the right from the substrate body 1210.

[0346] For example, one of the pair of third light source substrates 1200Cs arranged to be closer to the first vertical boundary (vertical boundary 15B arranged on the left side of FIG. 14 (in the -Y direction)) rather than closer to the second vertical boundary (vertical boundary 15B arranged on the right side of FIG. 14 (in the +Y direction)) can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the first vertical boundary (i.e., toward the left side of FIG. 14 (in the -Y direction)). Symmetrically, the third light source substrate 1200C of a pair of third light source substrates 1200C that is arranged closer to the second vertical boundary than to the first vertical boundary (i.e., the third light source substrate 1200C arranged on the right side of FIG. 14 (in the +Y direction)) may have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the second vertical boundary (i.e., toward the right side of FIG. 14 (in the +Y direction)).

[0347] In this case, for example, the spacing between the first vertical boundary and the third light source substrate 1200C adjacent to the first vertical boundary can substantially correspond to the spacing between the second vertical boundary and another third light source substrate 1200C adjacent to the second vertical boundary.

[0348] Using this structure, the third light source substrate 1200C can be arranged such that the substrate body 1210 is adjacent to the drive board 70, and the length of the wire C connecting the drive board 70 to the connector 1300 can be shortened.

[0349] In a plurality of light source substrates 1200, each of a pair of third light source substrates 1200C can be arranged to have the shortest possible spacing between the substrate body 1210 and the drive board 70.

[0350] For example, the pair of third light source substrates 1200C can be arranged adjacent to the central portion of the bottom housing in the second direction Y. The pair of third light source substrates 1200C can be arranged symmetrically based on a centerline passing through the center of the bottom housing 15 in the first direction Z. In this case, the substrate bodies of the pair of third light source substrates 1200C can be arranged adjacent to each other in the second direction Y.

[0351] For example, the connector 1300 disposed on the substrate body 1210 of each of the plurality of third light source substrates 1200C can be arranged to pass through the portion of the bottom housing 15 spaced apart from the second protrusion 15db.

[0352] For example, the display device 4 of Figures 14 and 15 can have a screen 12 with a diagonal length of 85 inches, but the length is not limited to this.

[0353] Figure 16 is a front view of the light source substrate and bottom housing of a display device according to some embodiments of the present disclosure.

[0354] Referring to FIG16, when describing the structure of the display device 5, components that are repeated with components of the display device 1 have the same reference numerals as those in the embodiments of FIG1 to FIG9, and their descriptions will not be repeated.

[0355] Referring to FIG16, in an embodiment of this disclosure, the display device 5 may include a plurality of light source substrates 1200. The display device 5 may include a driver board 70 electrically connected to each of the plurality of light source substrates 1200 to control the operation of a light source 1100 mounted on each light source substrate 1200. The driver board 70 may be electrically connected to the light source substrate 1200 via a wire C connected to a connector 1300 disposed on the substrate body 1210 of the light source substrate 1200.

[0356] Unlike the embodiments described above, the drive board 70 can be arranged offset from one of the vertical boundaries 15B of the bottom housing 15. For example, the drive board 70 can be arranged offset to one side from the center of the bottom housing 15 in the second direction Y. However, it is undesirable when the drive board 70 is arranged close to overlapping or nearly overlapping one of the vertical boundaries 15B of the bottom housing 15, because the wires C or electronic components connected to the drive board 70 may be interfered with by the inner boundary of the display housing. Therefore, the drive board 70 can be arranged at a position that is closer to or even inwardly spaced from one of the vertical boundaries 15B of the bottom housing 15 in the second direction Y, as shown in FIG16.

[0357] In this case, some of the light source substrates 1200A arranged adjacent to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y can be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the multiple substrate strips 1220.

[0358] Specifically, the display device 2 may include a pair of first light source substrates 1200A among a plurality of light source substrates 1200, which are closest to the boundaries 15A and 15B of the bottom housing 15 in the second direction Y. Each of the pair of first light source substrates 1200A may be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0359] For example, one of a pair of first light source substrates 1200A arranged closer to the first vertical boundary (on the left in the -Y direction of FIG. 16) rather than closer to the second vertical boundary (on the right in the +Y direction of FIG. 16) (i.e., the first light source substrate 1200A arranged on the left side of FIG. 16 (in the -Y direction)) can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the first vertical boundary (i.e., toward the left side of FIG. 16 (in the -Y direction)). Symmetrically, the other of a pair of first light source substrates 1200A arranged closer to the second vertical boundary rather than closer to the first vertical boundary (i.e., the first light source substrate 1200A arranged on the right side of FIG. 16 (in the +Y direction)) can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the second vertical boundary (i.e., toward the right side of FIG. 16 (in the +Y direction)).

[0360] In this case, for example, the spacing between the first vertical boundary and the first light source substrate 1200A adjacent to the first vertical boundary can substantially correspond to the spacing between the second vertical boundary and another first light source substrate 1200A adjacent to the second vertical boundary.

[0361] As shown in FIG. 16, a row may include a pair of first light source substrates 1200A. Each of a pair of columns in the second direction Y, closest to the vertical boundary 15B of the bottom housing 15, may include the same number of first light source substrates 1200A as the row. For example, in the embodiment of FIG. 16, the display device 5 may include a total of four first light source substrates 1200A.

[0362] Using this structure, the length of the wire C extending from the drive board 70 to the connector 1300 arranged on the substrate body 1210 of the first light source substrate 1200A can be shortened, which can save on product manufacturing costs. In addition, noise from the current flowing in the wire C connecting the drive board 70 to the first light source substrate 1200A can be reduced.

[0363] The display device 5 may include a pair of second light source substrates 1200B disposed between a pair of first light source substrates 1200A. The pair of second light source substrates 1200B may be arranged to be further away from the boundary 15A or 15B of the bottom housing 15 than the pair of first light source substrates 1200A in the second direction Y. The pair of second light source substrates 1200B may be positioned closer to the inner side of the bottom housing 15 than the pair of first light source substrates 1200A in the second direction Y. The pair of second light source substrates 1200B may be arranged to face each other in the second direction Y.

[0364] As shown in FIG16, a row may include a pair of second light source substrates 1200B. For example, in the embodiment of FIG16, the display device 5 may include a total of four second light source substrates 1200B.

[0365] In this configuration, one or more of the plurality of second light source substrates 1200B that are closer to the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is closer to the drive plate 70 in the second direction Y than the plurality of substrate strips 1220. The one or more second light source substrates 1200B arranged to be closer to the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0366] Using this structure, one or more of the second light source substrates 1200B that are closer to the drive board 70 in the second direction Y can have a reduced spacing between the connector 1300 and the drive board 70, thereby making the length of the wire C connecting the connector 1300 and the drive board 70 shorter.

[0367] Meanwhile, the second light source substrate 1200B located on the left (in the -Y direction) and the second light source substrate 1200B located on the right (in the +Y direction) relative to the center portion of the bottom housing 15 among the plurality of second light source substrates 1200B can be arranged symmetrically based on the center portion of the bottom housing 15.

[0368] Therefore, one or more of the plurality of second light source substrates 1200B that are further away from the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is further away from the drive plate 70 in the second direction Y than the plurality of substrate strips 1220. One or more of the plurality of second light source substrates 1200B that are further away from the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0369] For example, one of a pair of second light source substrates 1200B arranged closer to the first vertical boundary (on the left in the -Y direction of FIG. 16) rather than closer to the second vertical boundary (on the right in the +Y direction of FIG. 16) (i.e., the second light source substrate 1200B arranged on the left side of FIG. 16 (in the -Y direction)) can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the second vertical boundary (i.e., toward the right side of FIG. 16 (in the +Y direction)). Symmetrically, the other of a pair of second light source substrates 1200B arranged closer to the second vertical boundary rather than closer to the first vertical boundary (i.e., the second light source substrate 1200B arranged on the right side of FIG. 16 (in the +Y direction)) can be arranged such that a plurality of substrate strips 1220 extend from the substrate body 1210 toward the first vertical boundary (i.e., toward the left side of FIG. 16 (in the -Y direction)).

[0370] In this case, for example, the spacing between the first vertical boundary and the second light source substrate 1200B adjacent to the first vertical boundary can substantially correspond to the spacing between the second vertical boundary and another second light source substrate 1200B adjacent to the second vertical boundary.

[0371] For example, the display device 5 of Figure 16 may have a screen 12 with a diagonal length of 65 inches, but the length is not limited to this.

[0372] Figure 17 is a front view of the light source substrate and bottom housing of a display device according to some embodiments of the present disclosure.

[0373] Referring to FIG17, when describing the structure of display device 5-1, components that are repeated with components of display device 1 have the same reference numerals as those in the embodiments of FIG1 to 9 and FIG16, and their descriptions will not be repeated.

[0374] Referring to FIG17, in some embodiments of this disclosure, the display device 5-1 may include a plurality of light source substrates 1200 and a driver board 70. In the embodiment of FIG17, the driver board 70 is arranged in a position almost identical to that in the embodiment of FIG16, and therefore will not be described in detail again.

[0375] Furthermore, the layout of the first light source substrate 1200A, which is arranged closest to the boundary 15A or 15B of the bottom housing 15 in the second direction Y among the plurality of light source substrates 1200 included in the display device 5-1, is the same as in the embodiment of FIG16, and therefore will not be described in detail again.

[0376] The display device 5-1 may include a pair of second light source substrates 1200B and 1200B-1 disposed between a pair of first light source substrates 1200A. The pair of second light source substrates 1200B and 1200B-1 may be arranged further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the pair of first light source substrates 1200A. The pair of second light source substrates 1200B and 1200B-1 may be positioned closer to the inner side of the bottom housing 15 in the second direction Y than the pair of first light source substrates 1200A. The pair of second light source substrates 1200B and 1200B-1 may be arranged side-by-side in the second direction Y.

[0377] As shown in Figure 17, a row may include a pair of second light source substrates 1200B and 1200B-1. For example, in the embodiment of Figure 17, the display device 5-1 may include a total of four second light source substrates 1200B and 1200B-1.

[0378] In this configuration, one or more of the plurality of second light source substrates 1200B and 1200B-1 that are closer to the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is closer to the drive plate 70 in the second direction Y than the plurality of substrate strips 1220. One or more of the plurality of second light source substrates 1200B arranged to be closer to the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is closer to the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0379] Furthermore, one or more of the plurality of second light source substrates 1200B and 1200B-1 that are further away from the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is closer to the drive plate 70 in the second direction Y than the plurality of substrate strips 1220. One or more of the plurality of second light source substrates 1200B and 1200B-1 that are further away from the drive plate 70 in the second direction Y can be arranged such that the substrate body 1210 is further away from the boundary 15A or 15B of the bottom housing 15 in the second direction Y than the plurality of substrate strips 1220.

[0380] Assuming that the drive board 70 is arranged closer to the first vertical boundary (the left boundary of FIG. 17 (in the -Y direction)) of a pair of second light source substrates 1200B and 1200B-1, the second light source substrate 1200B arranged closer to the first vertical boundary rather than closer to the second vertical boundary (the right boundary of FIG. 17 (in the +Y direction)) (the second light source substrate 1200B arranged on the left side of FIG. 17 (in the -Y direction)) can be arranged to have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the first vertical boundary (i.e., toward the right side of FIG. 17 (in the +Y direction)). Symmetrically, the other second light source substrate 1200B-1 of the pair of second light source substrates 1200B and 1200B-1, which is arranged closer to the second vertical boundary than to the first vertical boundary (i.e., the second light source substrate 1200B-1 arranged on the right side of FIG. 17 (in the +Y direction), may have a plurality of substrate strips 1220 extending from the substrate body 1210 toward the first vertical boundary (i.e., toward the right side of FIG. 17 (in the +Y direction)). In other words, each of the pair of second light source substrates 1200B and 1200B-1 may have a plurality of substrate strips 1220 extending from the substrate body 1210 in a direction away from the extension of the drive plate 70.

[0381] Using this structure, the extension length of the wire C connecting the second light source substrate 1200B-1, which is farther away from the drive board 70 in the second direction Y, to the drive board 70 can be shortened, thus saving on product manufacturing costs. Furthermore, noise from the current flowing in the wire C can be reduced more effectively.

[0382] In this case, for example, the spacing between the first vertical boundary and the second light source substrate 1200B adjacent to the first vertical boundary can substantially correspond to the spacing between the second vertical boundary and another second light source substrate 1200B-1 adjacent to the second vertical boundary.

[0383] For example, the display device 5-1 of Figure 17 may have a screen 12 with a diagonal length of 65 inches, but the length is not limited to this.

[0384] In the embodiments described in conjunction with Figures 1 to 17, for ease of explanation, the terms “first light source substrate,” “second light source substrate,” “third light source substrate,” etc., are named based on location to distinguish multiple light source substrates, and this disclosure is not limited by the ordinal number given to the terms.

[0385] Meanwhile, although in the embodiments of Figures 1 to 17, the light source substrate is arranged such that the corresponding substrate strip extends from the substrate body in the horizontal direction Y, the light source substrate can be arranged such that the corresponding substrate strip extends from the substrate body in the vertical direction Z. In this case, for example, at least some of the multiple light source substrates can be arranged further away from the horizontal boundary of the bottom housing than the multiple substrate strips. In other words, the substrate strips of the light source substrate can each extend from the substrate body toward the closer of a pair of horizontal boundaries of the bottom housing. This can reduce the spacing between the substrate body of the light source substrate and the drive board, as well as the length of the wires connecting the connector to the drive board.
