[0066] Figure 2 is an exploded perspective view of a display device according to an embodiment. Figure 3 is a cross-sectional view of a display panel included in a display device according to an embodiment.

[0067] Reference Figure 2 and Figure 3 Various components configured to generate the image I on the screen 12 may be provided inside the main body 11 .

[0068] For example, the body 11 may include a light source device 100 as a surface light source, a display panel 20 configured to block or transmit light emitted from the light source device 100, a control component 50 configured to control the operation of the light source device 100 and the display panel 20, and a power supply component 60 configured to supply power to the light source device 100 and the display panel 20. In addition, the body 11 may include a bezel 13, a frame middle mold 14, a bottom chassis 15, and a back cover 16, which are provided to support the display panel 20, the light source device 100, the control component 50, and the power supply component 60.

[0069] The light source device 100 may include a point light source configured to emit monochromatic light or white light. The light source device 100 may refract, reflect, and scatter light so as to convert the light emitted from the point light source into uniform surface light. As described above, the light source device 100 may refract, reflect, and scatter the light emitted from the point light source, thereby emitting uniform surface light toward the front side. The light source device 100 may be referred to as a backlight unit 100.

[0070] The light source device 100 is described in more detail below.

[0071] The display panel 20 may be provided in front of the light source device 100 and block or transmit light emitted from the light source device 100 to form an image I.

[0072] The front surface of the display panel 20 may form the screen 12 of the display device 10 described above, and the display panel 20 may form the plurality of pixels P. In the display panel 20, the plurality of pixels P may independently block or transmit light from the light source device 100. In addition, the light transmitted through the plurality of pixels P may form an image I displayed on the screen 12.

[0073] For example, Figure 3As shown, 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 .

[0074] The first transparent substrate 22 and the second transparent substrate 28 may fixedly support the pixel electrode 23, the TFT 24, the liquid crystal layer 25, the common electrode 26, and the color filter 27. The first transparent substrate 22 and the second transparent substrate 28 may be formed of tempered glass or a transparent resin.

[0075] The first polarizing film 21 and the second polarizing film 29 can be provided on the outer sides of the first transparent substrate 22 and the second transparent substrate 28. Each of the first polarizing film 21 and the second polarizing film 29 can transmit specific polarized light and block (reflect or absorb) other polarized light. For example, the first polarizing film 21 can transmit light polarized in the first direction and block (reflect or absorb) other polarized light. In addition, the second polarizing film 29 can transmit light polarized in the second direction and block (reflect or absorb) other polarized light. In this case, the first direction and the second direction can be perpendicular to each other. Therefore, the polarized light passing through the first polarizing film 21 may not directly pass through the second polarizing film 29.

[0076] The color filter 27 may be provided on the inner side of the second transparent substrate 28. The color filter 27 may include a red color filter 27R that transmits red light, a green color filter 27G that transmits green light, and a blue color filter 27B that transmits blue light. The red color filter 27R, the green color filter 27G, and the blue color filter 27B may be arranged in parallel with each other. The area occupied by the color filter 27 may correspond to the above-mentioned pixel P. The area occupied by the red color filter 27R may correspond to the red sub-pixel P. R , the area occupied by the green color filter 27G may correspond to the green sub-pixel P G , the area occupied by the blue color filter 27B may correspond to the blue sub-pixel P B .

[0078] The TFT 24 may be provided in the inner side of the second transparent substrate 28. The TFT 24 may be turned on (closed) or off (open) by image data provided from the panel driver 30. In addition, depending on whether the TFT 24 is turned on (closed) or off (open), an electric field may be formed or removed between the pixel electrode 23 and the common electrode 26.

[0079] A liquid crystal layer 25 may be formed between the pixel electrode 23 and the common electrode 26, and the liquid crystal layer 25 may be filled with liquid crystal molecules 25a. Liquid crystal represents an intermediate state between a solid (crystal) and a liquid. Liquid crystal may exhibit optical properties according to changes in an electric field. For example, in a liquid crystal, the orientation of molecules forming the liquid crystal may change according to changes in an electric field. As a result, the optical properties of the liquid crystal layer 25 may change according to the presence or absence of an electric field passing through the liquid crystal layer 25. For example, the liquid crystal layer 25 may rotate the polarization direction of light relative to the optical axis according to the presence or absence of an electric field. Therefore, the polarization direction of polarized light passing through the first polarizing film 21 may rotate while passing through the liquid crystal layer 25, and the polarized light may pass through the second polarizing film 29.

[0080] A cable 20 a configured to transmit image data to the display panel 20 and a display driver integrated circuit (DDI) (hereinafter referred to as “panel driver”) 30 configured to process digital image data and output an analog image signal may be provided at one side of the display panel 20 .

[0081] The cable 20a may electrically connect the control assembly 50 / power supply assembly 60 to the panel driver 30, and may also electrically connect the panel driver 30 to the display panel 20. The cable 20a may include a flexible flat cable or a bendable film cable.

[0082] The panel driver 30 may receive image data and power from the control component 50 / power supply component 60 through the cable 20a. The panel driver 30 may provide image data and driving current to the display panel 20 through the cable 20a.

[0083] In addition, the cable 20a and the panel driver 30 may be integrally implemented as a thin film cable, a chip on film (COF) or a tape carrier package (TCP). In other words, the panel driver 30 may be arranged on the cable 20b. However, the embodiments of the present disclosure are not limited thereto, and the panel driver 30 may be arranged on the display panel 20.

[0084] Control component 50 may include control circuitry configured to control operations of display panel 20 and light source device 100.

[0085] The power supply assembly 60 may include a power supply circuit configured to supply power to the display panel 20 and the light source device 100. The power supply circuit may supply power to the control assembly 50, the light source device 100, and the display panel 20.

[0086] The control component 50 and the power supply component 60 may be implemented as a printed circuit board and various circuits mounted on the printed circuit board. For example, the power supply circuit may include a capacitor, a coil, a resistor element, a processor, and a power supply circuit board, and the capacitor, the coil, the resistor element, and the processor are mounted on the power supply circuit board. In addition, the control circuit may include a memory, a processor, and a control circuit board on which the memory and the processor are mounted.

[0087] The light source device 100 will be described.

[0088] Figure 4 is an exploded perspective view of a light source device included in a display device according to an embodiment. Figure 5 It is shown Figure 4 A view showing a combination of a light source module and a reflective sheet included in a light source device.

[0089] Reference Figure 4 and Figure 5 The light source device 100 may include a light source module 110 configured to generate light, a reflective sheet 120 configured to reflect light, a diffusion plate 130 configured to uniformly diffuse light, and an optical sheet 140 configured to increase brightness of emitted light.

[0090] The light source module 110 may include a plurality of light sources 111 configured to emit light and a light source substrate 112 provided to support / fix the plurality of light sources 111. The light source substrate 112 may be referred to as a substrate 112.

[0091] The plurality of light sources 111 may be arranged in a predetermined pattern to emit light having uniform brightness. The plurality of light sources 111 may be arranged in such a manner that a distance between one light source and a light source adjacent thereto is the same.

[0092] The light source 111 may be configured to emit monochromatic light (light of a specific wavelength, such as blue light) or white light (for example, mixed light of red, green and blue light) in various directions by receiving power. For example, the light source 111 may include a light emitting diode (LED).

[0093] The substrate 112 may fix the plurality of light sources 111 to prevent a change in the positions of the light sources 111. In addition, the substrate 112 may supply power to the light sources 111 for the light sources 111 to emit light.

[0094] The substrate 112 may fix the plurality of light sources 111 and may be configured with synthetic resin or tempered glass or a printed circuit board (PCB) on which conductive power lines for supplying power to the light sources 111 are formed.

[0095] The substrate 112 may be formed of an insulating layer formed of synthetic resin or tempered glass. A circuit may be printed on one side of the substrate 112. For example, a circuit pattern and / or line may be formed on the front surface of the substrate 112 facing the display panel 20.

[0096] The display device according to the embodiment may further include a support member 500. The support member 500 may be mounted on the substrate 112. The support member 500 may be mounted on the upper surface of the substrate 112 by welding. The support member 500 may be provided in plurality. A plurality of support members 500 may be provided between the substrate 112 and the optical members 130 and 140. The plurality of support members 500 may be mounted on the upper surface of the substrate 112 to support the optical members 130 and 140.

[0097] The support member 500 may be provided to maintain the optical characteristics of the light source device 100 by maintaining an optical distance (OD) between the light source 111 and the diffusion plate 130 and / or the optical sheet 140. The support member 500 may be provided in a length capable of maintaining the optical characteristics of the light source device 100.

[0098] The support member 500 may be a jumper support member 500, which is arranged in an area where circuit patterns intersect with each other so as to allow the circuit patterns to be connected to each other without interference. For example, the jumper support member 500 may be arranged in an area where a plurality of lines 400 intersect with each other so as to allow the plurality of lines 400 to be connected to each other without interference. Since the jumper support member 500 allows the lines 400 provided on one side of the substrate 112 to intersect with each other while supporting the optical members 130 and 140, the number of jumper connectors required in the area where the lines intersect can be reduced. Therefore, by reducing the number of jumper connectors, costs can be reduced and process efficiency can be improved. Details about the jumper support member 500 will be described later.

[0099] The reflective sheet 120 may reflect light emitted from the plurality of light sources 111 to the front side or in a direction close to the front side.

[0100] In the reflective sheet 120, a plurality of penetration holes 120a are formed at positions corresponding to each of the plurality of light sources 111 of the light source module 110. In addition, the light sources 111 of the light source module 110 may pass through the penetration holes 120a and protrude to the front of the reflective sheet 120.

[0101] In addition, a plurality of supporter holes 120b may be formed in the reflective sheet 120 at positions corresponding to the supporters 500. The supporters 500 may pass through the supporter holes 120b and protrude to support the diffusion plate and / or the optical sheet 140. The supporters 500 may be disposed in the supporter holes 120b.

[0102] For example, Figure 5 As shown in the upper part of FIG. 1 , during the process of assembling the reflective sheet 120 and the light source module 110, the plurality of light sources 111 of the light source module 110 are inserted into the through holes 120a formed on the reflective sheet 120, and the support member 500 is inserted into the support member hole 120b. Figure 5 As shown in the lower part of FIG. 1 , the substrate 112 of the light source module 110 may be disposed behind the reflective sheet 120, but the plurality of light sources 111 of the light source module 110 may be disposed in front of the reflective sheet 120. Therefore, the plurality of light sources 111 may emit light in front of the reflective sheet 120.

[0103] The plurality of light sources 111 may emit light in various directions in front of the reflective sheet 120. Light may be emitted not only from the light sources 111 toward the diffusion plate 130 but also from the light sources 111 toward the reflective sheet 120. The reflective sheet 120 may reflect light emitted toward the reflective sheet 120 toward the diffusion plate 130.

[0104] The light emitted from the light source 111 may pass through various objects, such as the diffusion plate 130 and the optical sheet 140. Among incident light beams passing through the diffusion plate 130 and the optical sheet 140, some of the incident light beams may be reflected from the surface of the diffusion plate 130 and the surface of the optical sheet 140. The reflective sheet 120 may reflect the light reflected by the diffusion plate 130 and the optical sheet 140.

[0105] The diffusion plate 130 may be provided in front of the light source module 110 and the reflective sheet 120 , and may uniformly distribute light emitted from the light source 111 of the light source module 110 .

[0106] In the diffusion plate 130, the diffusion plate 130 may diffuse light emitted from the plurality of light sources 111 to remove uneven brightness caused by the plurality of light sources 111. In other words, the diffusion plate 130 may uniformly emit uneven light of the plurality of light sources 111 to the front surface.

[0107] The optical sheet 140 may include various sheets for improving brightness and brightness uniformity. For example, the optical sheet 140 may include a diffusion sheet 141, a first prism sheet 142, a second prism sheet 143, and a reflective polarizing sheet 144.

[0108] The diffusion sheet 141 may diffuse light to achieve brightness uniformity. Light emitted from the light source 111 may be diffused by the diffusion plate 130 and may be diffused again by the diffusion sheet 141 included in the optical sheet 140.

[0109] The first and second prism sheets 142 and 143 may increase brightness by concentrating light diffused by the diffusion sheet 141. The first and second prism sheets 142 and 143 may include a prism pattern in a triangular prism shape, and the prism pattern provided in plurality may be disposed adjacent to each other to form a plurality of stripes.

[0110] The reflective polarizer 144 is a polarizing film and can transmit some of the incident light beams and reflect other light beams to improve brightness. For example, the reflective polarizer 144 can transmit light polarized in the same direction as the predetermined polarization direction of the reflective polarizer 144, and can reflect light polarized in a direction different from the polarization direction of the reflective polarizer 144. In addition, the light reflected by the reflective polarizer 144 is recycled inside the light source device 100, so the brightness of the display device 10 can be improved by light recycling.

[0111] The optical sheet 140 is not limited to Figure 4 and Figure 5 The sheet or film shown, and may include more various sheets (such as a protective sheet) or films.

[0112] Figure 6 is a perspective view of a light source included in a light source device according to an embodiment. Figure 7 yes Figure 6 An exploded perspective view of the light source is shown. Figure 8 yes Figure 6 The light source and the substrate are shown in a cross-sectional view taken along the direction AA'.

[0113] Reference Figures 6 to 8 , the light source module 110 may include the plurality of light sources 111. The plurality of light sources 111 may protrude from the rear of the reflective sheet 120 to the front of the reflective sheet 120 by passing through the through holes 120a. Therefore, the light sources 111 and a portion of the substrate 112 may be exposed toward the front of the reflective sheet 120 through the through holes 120a.

[0114] The light source 111 may include an electrical / mechanical structure disposed in a region defined by the through hole 120a of the reflective sheet 120. Each of the plurality of light sources 111 may include a light emitting diode 210 and an optical dome 220.

[0115] The number of light sources 111 may be increased to improve uniformity of surface light emitted from the light source device 100 and to improve contrast through local dimming.

[0116] The light emitting diode 210 may include a P-type semiconductor and an N-type semiconductor for emitting light through recombination of holes and electrons. In addition, the light emitting diode 210 may be provided with a pair of electrodes 210a for supplying holes and electrons to the P-type semiconductor and the N-type semiconductor, respectively.

[0117] The light emitting diode 210 can convert electrical energy into light energy. In other words, the light emitting diode 210 can emit light having a maximum intensity at a predetermined wavelength of the supplied power. For example, the light emitting diode 210 can emit blue light having a peak at a wavelength indicating blue (e.g., a wavelength between 450nm and 495nm).

[0118] The light emitting diode 210 may be directly attached to the substrate 112 in a chip on board (COB) method. In other words, the light source 111 may include the light emitting diode 210, wherein the light emitting diode chip or light emitting diode die is directly attached to the substrate 112 without additional packaging.

[0119] In order to reduce the area occupied by the light emitting diode 210, the light emitting diode 210 may be manufactured as a flip chip type not including a Zener diode. When the flip chip type light emitting diode 210 as a semiconductor device is attached to the substrate 112, the electrode pattern of the semiconductor device may be fused to the substrate 112 as it is without using an intermediate medium such as a metal lead (wire) or a ball grid array (BGA).

[0120] Since the metal leads (wires) or the ball grid array are omitted as described above, the size of the light source 111 including the flip-chip type light emitting diode 210 can be reduced.

[0121] The light source module 110 may be manufactured in which the flip chip type light emitting diode 210 is attached to the substrate 112 in a chip on board method to reduce the size of the light source 111 .

[0122] In the above, the flip chip type light emitting diode 210 directly fused to the substrate 112 in a chip-on-board manner has been described, but the light source 111 is not limited to the flip chip type light emitting diode. For example, the light source 111 may include a package type light emitting diode.

[0123] A feeding line 230 and a feeding pad 240 for supplying power to the light emitting diode 210 are provided on the substrate 112 .

[0124] A feed line 230 for supplying an electrical signal and / or power from the control component 50 and / or the power component 60 to the light emitting diode 210 is provided on the substrate 112 .

[0125] like Figure 8As shown, the substrate 112 may be formed by alternately stacking non-conductive insulating layers 251 and conductive conductive layers 252 .

[0126] The insulating layer 251 may include a first surface 251a and a second surface 251b, and the conductive layer 252 may also include a first surface 252a and a second surface 252b. The conductive layer 252 may be stacked on a first side of the insulating layer 251. For example, the conductive layer 252 may be stacked on the first surface 251a of the insulating layer 251. In addition, the jumper support 500 to be described later may be disposed on the first side of the conductive layer 252. For example, the jumper support 500 may be disposed on the first surface 252a of the conductive layer 252, and the jumper support 500 may be electrically connected to the conductive layer 252 through the welding portions 601 and 602 to thereby connect the first portion 401 and the second portion 402 of the wire 400.

[0127] A line or pattern through which power and / or electrical signals flow may be formed on the conductive layer 252. The conductive layer 252 may be formed of various materials having conductivity. For example, the conductive layer 252 may be formed of various metal materials such as copper (Cu), tin (Sn), aluminum (Al) or alloys thereof. The conductive layer 252 may be stacked on one surface of the insulating layer 251.

[0128] The dielectric of the insulating layer 251 may insulate between lines or patterns of the conductive layer 252. The insulating layer 251 may be formed of a dielectric for electrical insulation, such as FR-4.

[0129] The feeding line 230 may be implemented by a line or a pattern formed on the conductive layer 252. The feeding line 230 may be electrically connected to the light emitting diode 210 through the feeding pad 240. The feeding pad 240 may be formed in such a manner that the feeding line 230 is exposed to the outside.

[0130] A protective layer 253 may be formed at the outermost portion of the substrate 112, and the protective layer 253 is configured to prevent or inhibit damage to the substrate 112 caused by an external impact and / or damage to the substrate 112 caused by a chemical action (e.g., corrosion, etc.) and / or damage to the substrate 112 caused by an optical action. The protective layer 253 may include a photo solder resist (PSR).

[0131] like Figure 8 As shown, the protection layer 253 may cover the feeding line 230 to prevent the feeding line 230 from being exposed to the outside.

[0132] For electrical contact between the feed line 230 and the light emitting diode 210, a window may be formed in the protective layer 253 to expose a portion of the feed line 230 to the outside. The portion of the feed line 230 exposed to the outside through the window of the protective layer 253 may form a feed pad 240.

[0133] A conductive adhesive material 240a for electrical contact between the feeding line 230 exposed to the outside and the electrode 210a of the light emitting diode 210 may be applied to the feeding pad 240. The conductive adhesive material 240a may be applied within the window of the protective layer 253.

[0134] The electrode 210 a of the light emitting diode 210 may be in contact with the conductive adhesive material 240 a , and the light emitting diode 210 may be electrically connected to the feeding line 230 through the conductive adhesive material 240 a .

[0135] The conductive adhesive material 240a may include solder having conductivity. However, the embodiments of the present disclosure are not limited thereto, and the conductive adhesive material 240a may include a conductive epoxy resin adhesive.

[0136] Power may be supplied to the light emitting diode 210 through the feeding line 230 and the feeding pad 240, and in response to the supply of power, the light emitting diode 210 may emit light. A pair of feeding pads 240 corresponding to each of a pair of electrodes 210a provided in the flip chip type light emitting diode 210 may be provided.

[0137] The optical dome 220 may cover the light emitting diode 210. The optical dome 220 may prevent or suppress damage to the light emitting diode 210 caused by an external mechanical action and / or damage to the light emitting diode 210 caused by a chemical action.

[0138] The optical dome 220 may have a dome shape formed in a manner of cutting a sphere into a surface not including its center, or may have a hemispherical shape formed in a manner of cutting a sphere into a surface including its center. A vertical cross section of the optical dome 220 may be an arcuate shape or a semicircular shape.

[0139] The optical dome 220 may be formed of silicone or epoxy. For example, molten silicone or epoxy may be discharged onto the light emitting diode 210 through a nozzle, and the discharged silicone or epoxy may be cured, thereby forming the optical dome 220.

[0140] Therefore, the shape of the optical dome 220 may vary depending on the viscosity of the liquid silicone or epoxy resin. For example, when the optical dome 220 is manufactured using silicon having a thixotropic index of about 2.7 to 3.3 (suitably 3.0), the optical dome 220 may have a dome ratio of about 0.25 to 0.31 (suitably 0.28), which represents the ratio of the height of the dome to the diameter of the bottom of the dome (height of the dome / diameter of the bottom). For example, the optical dome 220 formed of silicon having a thixotropic index of about 2.7 to 3.3 (suitably 3.0) may have a bottom diameter of about 2.5 mm and a height of about 0.7 mm.

[0141] The optical dome 220 may be optically transparent or translucent. Light emitted from the light emitting diode 210 may be emitted to the outside by passing through the optical dome 220.

[0142] In this case, the dome-shaped optical dome 220 may refract light like a lens. For example, light emitted from the light emitting diode 210 may be refracted by the optical dome 220 and thus may be dispersed.

[0143] As described above, the optical dome 220 may disperse light emitted from the light emitting diode 210 as well as protect the light emitting diode 210 from external mechanical and / or chemical or electrical effects.

[0144] An antistatic member may be formed near the optical dome 220 to protect the light emitting diode 210 from electrostatic discharge. The antistatic member may absorb electric shock caused by electrostatic discharge generated near the optical dome 220.

[0145] Reference Figure 8 , the light source module 110 may include a non-conductive insulating layer 251, a conductive conductive layer 252 stacked on a front surface 251a of the insulating layer 251 and including a feed line 230, and a non-conductive protective layer 253 stacked on a front surface 252a of the conductive layer 252. The insulating layer 251 may be referred to as a first layer, the conductive layer 252 may be referred to as a second layer, and the protective layer 253 may be referred to as a third layer.

[0146] The light emitting diode 210 may be disposed on the protective layer 253. Specifically, the light emitting diode 210 may be disposed on the front surface of the substrate 112 to cover the window formed on the protective layer 253.

[0147] A pair of feeding pads 240 may be formed on the conductive layer 252 and connected to the feeding line 230. The pair of feeding pads 240 may be electrically connected to the light emitting diode 210 through a window formed in the protective layer 253. The pair of feeding pads 240 may be arranged to be spaced apart from each other.

[0148] The light source module 110 may include a reflective auxiliary layer 260 .

[0149] In an implementation, the reflective auxiliary layer 260 may be formed between the pair of feeding pads 240 together with the protective layer 253 , thereby reducing a defect rate due to asymmetry in the sizes of the pair of feeding pads 240 .

[0150] The light emitting diode 210 may include a distributed Bragg reflector (DBR) layer 211 .

[0151] The DBR layer 211 is a multilayer reflector composed of two materials having different refractive indices. Due to the difference in the refractive index of each material, Fresnel reflection occurs at the interface of each DBR layer 211. Therefore, light incident on the DBR layer can be reflected at a wide range of angles, so the beam angle of the light emitting diode 210 can be set to about 165 degrees or more.

[0152] Light emitted from the light emitting diode 210 may be reflected by the DBR layer 211 and reflected again by the reflective auxiliary layer 260. Therefore, loss of light traveling into a space between a pair of feeding pads 240 may be prevented.

[0153] Specifically, since the reflection auxiliary layer 260 is formed of a material having a higher reflectivity than the insulating layer 251, the reflection auxiliary layer 260 can cover the front of the insulating layer 251 to prevent light traveling to the rear of the light emitting diode 210 from being absorbed by the insulating layer 251 and causing light loss.

[0154] Fig. 9 is a view showing a plurality of light sources divided into a plurality of dimming blocks in a display device according to an embodiment. Fig.10 is a control block diagram of a display device according to an embodiment.

[0155] In order to improve power consumption while increasing contrast, the display device 10 may perform local dimming to change the brightness of light of each area of ​​the light source device 100 in conjunction with an output image.

[0156] For example, the display device 10 can reduce the brightness of the light of the light source 111 of the light source device 100 corresponding to the dark part of the image to make the dark part of the image darker, and the display device 10 can increase the brightness of the light of the light source 111 of the light source device 100 corresponding to the bright part of the image to make the bright part of the image brighter. Therefore, the contrast of the image can be improved.

[0157] The display device 10 can divide the light source device 100 into a plurality of blocks and independently adjust the current of each block according to the input image. The image transmission from the display device 10 can be performed by local dimming driving for each frame, and the driving of the current can be adjusted according to the number of blocks of the light source 111 divided in the light source device 100.

[0158] As a result, the display device 10 can effectively improve the contrast ratio by reducing the supply current to the dimming block corresponding to the dark area of ​​the input image and by increasing the supply current to the dimming block corresponding to the bright area of ​​the input image.

[0159] For local dimming, the plurality of light sources 111 included in the light source device 100 may be divided into a plurality of dimming blocks 200. For example, Fig. 9As shown, the plurality of dimming blocks 200 may be composed of 5 rows and 12 columns, and thus a total of 60 dimming blocks may be provided. However, the number of dimming blocks 200 is not limited thereto.

[0160] Reference Fig. 9 , each of the plurality of dimming blocks 200 may include at least one light source 111. The light source device 100 may supply the same driving current to the light sources 111 belonging to the same dimming block 200, and the light sources 111 belonging to the same dimming block 200 may emit light of the same brightness.

[0161] In addition, the light source device 100 can supply different driving currents to the light sources 111 belonging to different dimming blocks 200 according to the dimming data, so the light sources 111 belonging to different dimming blocks 200 can emit light with different brightness.

[0162] The plurality of dimming blocks 200 may include N*M light sources arranged in an N*M matrix (N and M are natural numbers). The N*M matrix means a matrix having N rows and M columns.

[0163] Since each light source 111 includes a light emitting diode, each of the plurality of dimming blocks 200 may include N*M light emitting diodes.

[0164] The plurality of dimming blocks 200 may be disposed on the substrate 112 . That is, N*M light emitting diodes may be disposed on the substrate 112 .

[0165] Reference Fig.10 , the display device 10 may include a content receiver 80 , an image processor 90 , a panel driver 30 , a display panel 20 , a dimming driver 170 , and a light source device 100 .

[0166] The content receiver 80 may include a receiving terminal 81 that receives content including a video signal and / or an audio signal from a content source, and a tuner 82 .

[0167] The receiving end 81 may receive video signals and audio signals from a content source via a cable.

[0168] The tuner 82 may receive a broadcast signal from a broadcast receiving antenna or a wired cable. In addition, the tuner 82 may extract a broadcast signal of a channel selected by a user from the broadcast signal.

[0169] The content receiver 80 may receive a video signal and an audio signal from a content source through a receiving terminal 81 and / or a tuner 82. The content receiver 80 may output the video signal and / or the audio signal received through the receiving terminal 81 and / or the tuner 82 to the image processor 90.

[0170] The image processor 90 may include a processor 91 configured to process image data and a memory 92 configured to memorize / store a program and data for processing the image data.

[0171] The memory 92 may store programs and data for processing a video signal and / or an audio signal. In addition, the memory 92 may temporarily store data generated when processing a video signal and / or an audio signal.

[0172] The processor 91 may receive a video signal and / or an audio signal from the content receiver 80. The processor 91 may decode the video signal into image data. The processor 91 may generate dimming data from the image data. In addition, the processor 91 may output the image data and the dimming data to the panel driver 30 and the dimming driver 170, respectively.

[0173] The image processor 90 may generate image data and dimming data from the video signal obtained through the content receiver 80. In addition, the image processor 90 may transmit the image data and the dimming data to the display panel 20 and the light source device 100, respectively.

[0174] The image data may include information on the intensity of light transmitted by each of the plurality of pixels (or a plurality of sub-pixels) included in the display panel 20. The image data may be provided to the display panel 20 through the panel driver 30.

[0175] The panel driver 30 may receive image data from the image processor 90. The panel driver 30 may drive the display panel 20 according to the image data. In other words, the panel driver 30 may convert image data (hereinafter referred to as "digital image data") as a digital signal into an analog image signal as an analog voltage signal. The panel driver 30 may provide the analog image signal to the display panel 20. The optical properties (e.g., transmittance) of the plurality of pixels included in the display panel 20 may be changed according to the analog image signal.

[0176] The panel driver 30 may include a timing controller, a data driver, a scan driver, and the like.

[0177] The timing controller may receive image data from the image processor 90. The timing controller may output the image data and the drive control signal to the data driver and the scan driver. The drive control signal may include a scan control signal and a data control signal. The scan control signal and the data control signal may be used to control the operation of the scan driver and the data driver, respectively.

[0178] The scan driver may receive a scan control signal from the timing controller. The scan driver may activate the input of any one of the multiple rows in the display panel 20 according to the scan control signal. In other words, the scan driver may convert the pixels included in one row among the multiple pixels arranged in multiple rows and columns into a state capable of receiving an analog image signal. At this time, the pixels other than the pixels whose input is activated by the scan driver cannot receive the analog image signal.

[0179] The data driver may receive image data and a data control signal from the timing controller. The data driver may output the image data to the display panel 20 according to the data control signal. For example, the data driver may receive digital image data from the timing controller. The data driver may convert the digital image data into an analog image signal. In addition, the data driver may provide an analog image signal to pixels included in any row whose input is activated by the scan driver. At this time, the pixels whose input is activated by the scan driver may receive the analog image signal. The optical properties (e.g., transmittance) of the pixels whose input is activated change according to the received analog image signal.

[0180] The panel driver 30 may drive the display panel 20 according to the image data. Therefore, an image corresponding to the image data may be displayed on the display panel 20.

[0181] In addition, the dimming data may include information on the intensity of light emitted by each of the plurality of light sources (or a plurality of dimming blocks) included in the light source apparatus 100. The dimming data may be provided to the light source apparatus 100 through the dimming driver 170.

[0182] The light source device 100 may include the plurality of light sources 111 configured to emit light. The plurality of light sources 111 are arranged in a matrix form. In other words, the plurality of light sources 111 may be arranged in a plurality of rows and columns.

[0183] The light source device 100 may be divided into the plurality of dimming blocks 200. In addition, each of the plurality of dimming blocks 200 may include at least one light source.

[0184] The light source device 100 may output surface light by scattering the light emitted from the plurality of light sources 111. The display panel 20 may include the plurality of pixels, and the display panel 20 may control each of the plurality of pixels to transmit light or block light. An image may be formed by light passing through each of the plurality of pixels.

[0185] The light source device 100 may turn off a plurality of light sources corresponding to the dark portion of the image, thereby making the dark portion of the image darker. Therefore, since the dark portion of the image becomes darker, the contrast of the image may be improved.

[0186] Hereinafter, an operation of the light source device 100 controlling the plurality of light sources to emit light in an area corresponding to a bright portion of an image and controlling the plurality of light sources not to emit light in an area corresponding to a dark portion of an image will be referred to as “local dimming”.

[0187] For local dimming, the plurality of light sources 111 included in the light source device 100 may be divided into the plurality of dimming blocks 200, such as Fig. 9 As shown. Fig. 9 , a total of 60 dimming blocks in 5 rows and 12 columns are shown, but the number and arrangement of the dimming blocks are not limited to Fig. 9 Quantities and configurations shown.

[0188] Each of the plurality of dimming blocks 200 may include at least one light source 111. The light source device 100 may supply the same driving current to the light sources belonging to the same dimming block, and the light sources belonging to the same dimming block may emit light of the same brightness. For example, the light sources belonging to the same dimming block may be connected in series with each other, and thus the same driving current may be supplied to the light sources belonging to the same dimming block.

[0189] In addition, the light source device 100 may further include a plurality of driving elements 300 configured to control a driving current supplied to a light source included in each of the plurality of dimming blocks 200. The driving elements 300 may each be provided to correspond to at least one dimming block 200. In other words, the driving elements 300 may each drive the dimming blocks 200.

[0190] Since the light sources included in the dimming block are connected to each other in series, the light sources included in the dimming block may be operated as a unit and may form the light source block as a unit.

[0191] Therefore, hereinafter, “supplying a driving current to a dimming block” may be interpreted as having the same meaning as “supplying a driving current to a light source included in the dimming block”.

[0192] Fig. 9 Each dimming block includes nine light sources, but the number and arrangement of the light sources included in each dimming block are not limited to Fig. 9 Those shown in .

[0193] As described above, the image processor 90 may provide dimming data for local dimming to the light source device 100. The dimming data may include information about the brightness of each of the plurality of dimming blocks 200. For example, the dimming data may include information about the intensity of light output from a light source included in each of the plurality of dimming blocks 200.

[0194] The image processor 90 may obtain dimming data from the image data.

[0195] The image processor 90 may convert the image data into dimming data in various ways. For example, the image processor 90 may divide the image I based on the image data into a plurality of image blocks. The number of the plurality of image blocks may be equal to the number of the plurality of dimming blocks 200, and each of the plurality of image blocks may correspond to the plurality of dimming blocks 200.

[0196] The image processor 90 may obtain the brightness values ​​of the plurality of dimming blocks 200 from the image data of the plurality of image blocks. In addition, the image processor 90 may generate dimming data by combining the brightness values ​​of the plurality of dimming blocks 200.

[0197] For example, the image processor 90 may obtain the brightness value of each of the plurality of dimming blocks 200 based on a maximum value among brightness values ​​of pixels included in each image block.

[0198] A single image block may include a plurality of pixels, and image data of the single image block may include image data of the plurality of pixels (eg, red data, green data, blue data, etc.) The image processor 90 may calculate a brightness value of each pixel based on the image data of each pixel.

[0199] The image processor 90 may set the maximum value among the brightness values ​​of each pixel included in the image block as the brightness value of the dimming block corresponding to the image block. For example, the image processor 90 may set the maximum value among the brightness values ​​of the pixels included in the i-th image block as the brightness value of the i-th dimming block, and set the maximum value among the brightness values ​​of the pixels included in the j-th image block as the brightness value of the j-th dimming block.

[0200] The image processor 90 may generate dimming data by combining the brightness values ​​of the plurality of dimming blocks 200 .

[0201] The dimming driver 170 may receive dimming data from the image processor 90. The dimming driver 170 may drive the light source device 100 according to the dimming data. The dimming data may include information about the brightness of each of the plurality of dimming blocks 200 or information about the brightness of the light source included in each of the plurality of dimming blocks 200.

[0202] The dimming driver 170 may convert the dimming data, which is a digital voltage signal, into an analog driving current.

[0203] The dimming driver 170 may sequentially provide an analog dimming signal to the driving element 300 corresponding to each dimming block 200 in an active matrix method.

[0204] The dimming driver 170 may include a connector. The dimming driver 170 may transmit the scan signal, the data signal, and the power signal to the driving element 300 through the connector.

[0205] The plurality of dimming blocks 200 may be divided into a plurality of groups. The driving current may be supplied to the dimming blocks belonging to the same group at the same time, and the driving current may be supplied to the dimming blocks belonging to different groups in sequence at different times. The dimming driver 170 may activate a dimming block belonging to one of the plurality of groups and provide an analog dimming signal to the activated dimming block. Thereafter, the dimming driver 170 may activate dimming blocks belonging to different groups and provide an analog dimming signal to the activated dimming block.

[0206] For example, dimming blocks located in the same row may belong to the same group, and dimming blocks located in different rows may belong to different groups, but the group classification method is not limited thereto. The dimming driver 170 may activate a dimming block belonging to one group and provide an analog dimming signal to the activated dimming block. Thereafter, the dimming driver 170 may activate an input of a dimming block belonging to another row and provide an analog dimming signal to the dimming block in which the input is activated.

[0207] The driving circuit of each dimming block 200 can provide an analog driving current corresponding to the analog dimming signal to the light source module 110. The light source 111 included in the light source module 110 can emit light by the analog driving current. According to the dimming data, the light sources belonging to the same dimming block can emit light of the same intensity. In addition, according to the dimming data, the light sources belonging to different dimming blocks can emit light of different intensities.

[0208] Fig.11 An example of a connection structure of a dimming driver, a driving element, and a dimming block in a display device and a line arrangement in a light source device according to an embodiment is shown.

[0209] Reference Fig.11 Each of the plurality of dimming blocks may include a plurality of light sources (light emitting diodes) 111 connected in series. For example, the light emitting diodes 111 included in one dimming block 200 may be connected to the driving element 300 for emitting light.

[0210] Hereinafter, for convenience of description, a light source connected to the power line 410 in each of the plurality of dimming blocks 200 is defined as a 'starting light source', and a light source connected to the driving element 300 is defined as a 'last light source'.

[0211] Among multiple light sources 111 connected in series and belonging to one dimming block 200, the first light source 111 in the series connection can be connected to the power line 410 and receive power (driving voltage; VLED), and the last light source 111 in the series connection can be connected to the driving element 300.

[0212] When activated by the dimming driver 170 input, the driving element 300 may receive an analog dimming signal from the dimming driver 170 and store the received analog dimming signal. In addition, when deactivated by the input, the plurality of driving elements 300 may supply a driving current corresponding to the stored analog dimming signal to the plurality of light sources (light emitting diodes 111).

[0213] The driving element 300 may control a driving current supplied to each of the plurality of dimming blocks 200 when a driving voltage VLED is applied to the plurality of dimming blocks 200 .

[0214] To this end, the display device 10 may include a plurality of scan lines S for providing scan signals to the plurality of driving elements 300 and a plurality of data lines D1 and D2 for providing analog dimming signals to the plurality of driving elements 300 .

[0215] In addition, the display device 10 may include a power supply line 410 for supplying a driving voltage to the plurality of driving elements 300 .

[0216] The plurality of scan lines S, the plurality of data lines D1 and D2 , and the power supply line 410 may be formed on the substrate 112 .

[0217] The power line 410, the scan line S, and the data lines D1 and D2 may be formed on the substrate 112. For example, the power line 410, the scan line S, and the data lines D1 and D2 may all be formed on one second surface 112b of the substrate 112.

[0218] The plurality of driving elements 300 may include circuits of various topologies to implement active matrix driving.

[0219] For example, each of the plurality of driving elements 300 may include a circuit of 1C2T (one capacitor two transistors) topology. However, the circuit structure of the driving element 300 is not limited thereto. For example, the driving element 300 may include a 3T1C topology circuit, in which a transistor is added to correct the body effect of the driving transistor.

[0220] The driving element 300 may be provided as a single chip with an integrated driving circuit. In other words, the driving circuit may be integrated into one semiconductor chip.

[0221] The dimming driver 170 may transmit dimming data corresponding to an input image to the plurality of driving elements 300 through the data lines D1 and D2 .

[0222] In addition, the dimming driver 170 may transmit a timing signal corresponding to the light emission timing of the plurality of dimming blocks 200 to the plurality of driving elements 300 through the scan line S.

[0223] The plurality of driving elements 300 may control a driving current supplied to each of the plurality of dimming blocks 200 based on dimming data and a timing signal.

[0224] Fig.11 Some of the plurality of dimming blocks 200 are shown. As for the display device 10 according to the embodiment, local dimming requires more dimming blocks 200, more driving elements 300, more data lines D1 and D2, more scan lines S, and more power lines 410 connecting the dimming blocks 200 and the driving elements 300.

[0225] Therefore, it is required to simplify the arrangement of the data lines D1 and D2 , the scan lines S, and the power lines 410 on the substrate 112 .

[0226] According to one embodiment, the line may include a line connecting the data lines D1 and D2, the scan line S, the power line 410, the plurality of driving elements 300 and the plurality of dimming blocks 200 (hereinafter referred to as a "control line"), and a line connecting the plurality of light sources (hereinafter referred to as a "block line"). However, the type of line is not limited thereto. For example, the line may include a line connecting the plurality of driving elements 300 (hereinafter referred to as a "timing line 420").

[0227] The plurality of dimming blocks 200 may be arranged in a matrix on the front surface of the substrate 112 of the light source device 100, and each of the plurality of dimming blocks 200 may include the plurality of light sources 111. The plurality of light sources 111 may be turned on by receiving all of the data signal, the scan signal, and the power signal.

[0228] A plurality of light sources 111 belonging to one dimming block 200 may be arranged in a matrix form on the front surface of the substrate 112 .

[0229] According to an embodiment, the plurality of dimming blocks 200 included in two adjacent rows among the plurality of dimming blocks 200 may be electrically connected to a power line 410 extending between the two rows.

[0230] According to an embodiment, the power lines may be efficiently arranged by arranging only one power line 410 between two rows.

[0231] In one embodiment, the plurality of driving elements 300 may be alternately arranged between adjacent columns in a matrix formed by the plurality of dimming blocks 200 .

[0232] According to one embodiment, the length of the control lines of the plurality of driving elements 300 can be reduced. In addition, according to one embodiment, since the control lines of the plurality of driving elements 300 are alternately arranged between the columns of the plurality of dimming blocks 200, the wiring channels between the columns of the plurality of dimming blocks 200 can be ensured.

[0233] According to one embodiment, a timing line 420 connecting the plurality of driving elements 300 arranged between the first column and the second column and the plurality of driving elements 300 arranged in the third column and the fourth column may be formed.

[0234] In one implementation, the driving elements 300 disposed in different columns among the plurality of driving elements 300 may be electrically connected to each other through the timing line 420 .

[0235] According to an embodiment, since each driving element 300 is connected in series with an adjacent driving element 300 through the timing line 420 , timing signals may be shared with each other, and thus the number of data lines D1 and D2 and / or scan lines S may be reduced.

[0236] Fig.11 A line arrangement of the light source device 100 in which all of the above-described embodiments are combined is shown. However, the light source device 100 according to an embodiment may include a line arrangement implemented by each of the above-described embodiments, a combination of some of the above-described embodiments, or a combination of all of the above-described embodiments.

[0237] Fig.12 An example of line arrangement on a substrate of a display device according to an embodiment is shown. Fig.12 is a top view of the first side of the substrate 112. In other words, Fig.12 Components electrically connected to the first side of the substrate 112 are shown. The first side of the substrate 112 may be a side facing the display panel 20 and the optical members 130 and 140.

[0238] Reference Fig.12 , the display device includes a driving element 300 and a line 400 .

[0239] The driving element 300 may be provided in plurality and may include a first driving element 310 and a second driving element 320 .

[0240] The wire 400 may be connected to the dimming driver 170, the first and second driving elements 310 and 320, and the light source 111 to transmit signals. The wire 400 may transmit power from the dimming driver 170 including the connector to the light source 111 and the driving element 300.

[0241] The dimming driver 170 may be disposed on the light source substrate 112 or on a separate substrate other than the light source substrate 112 .

[0242] The wire 400 may include data lines D1 and D2, scan lines S, power lines V, timing lines 420, and output lines O. The wire 400 may include at least a portion of the feeding pad 240. The wire 400 may include various types of wires routed to the light source substrate 112 in addition to the above wires.

[0243] The data lines D1 and D2 may include a first data line D1 flowing from the dimming driver 170 to the first driving element 310 and a second data line D2 flowing from the dimming driver 170 to the second driving element 320. The first data line D1 and the second data line D2 may be provided in plural.

[0244] The scan line S may include a first scan line S1 flowing from the dimming driver 170 to the first driving element 310 and a second scan line flowing from the dimming driver 170 to the second driving element 320. The first scan line S1 and the second scan line S2 may be provided in plural.

[0245] The output lines O may transmit the data signal from the driving element 300 to the light source 111. The number of the output lines O may vary according to the scan signal and the data signal flowing from the dimming driver 170 to the driving element 300.

[0246] The output lines O may include a first output line O1 flowing from the first driving element 310 to the first light source 111 and a second output line O2 flowing from the second driving element 320 to the second light source 111 .

[0247] The numbers of the data lines D1 and D2 , the scan lines S, and the output lines O are not limited to the above examples.

[0248] The line 400 may be provided on one side of the substrate 112. For example, the line 400 may not be formed on both surfaces forming the outer side of the substrate 112, but may be formed only on one side forming the outer side of the substrate 112. For example, the line 400 may be provided on a first side of the substrate 112. The first side may be a side of the substrate 112 facing the display panel.

[0249] Since the lines 400 are formed only on the first side of the substrate 112, the lines 400 may intersect each other ( Fig.12The intersection area between the lines 400 may be formed in a plurality. For example, the data lines D1 and D2 for transmitting the data signal from the dimming driver 170 to the driving element 300 may intersect with the scan line S for transmitting the scan signal from the dimming driver 170 to the driving element 300. The data lines D1 and D2 may intersect with the power line V, which is configured to supply power (driving voltage; VLED) to the light source 111 and the driving element 300. The scan line S may intersect with the power line V. In addition, the output line O may intersect with the power line V, the scan line S, and one of the data lines D1 and D2.

[0250] For example, the first data line D1, the first scan line S1, and the power line V flowing to the first driving element 310 may intersect the first output line O1 flowing from the first driving element 310 to the first light source 111. In addition, the second data line D2, the second scan line S, and the power line V flowing to the second driving element 320 may intersect the second output line O2 flowing from the second driving element 320 to the second light source 111. In addition, the line 400 connected to the first driving element 310 may intersect the line 400 connected to the second driving element 320.

[0251] When the lines 400 intersect, one of the lines 400 may be disconnected. Therefore, it is required to prevent the line 400 from being disconnected so as to allow all the lines to be electrically connected. In addition, the line 400 may pass through the ground (GND) on one side of the substrate 112, and even in this case, it is necessary to prevent the disconnection of the line 400.

[0252] According to an embodiment, the display device may include a jumper supporter 500. For example, the light source device 100 may include the jumper supporter 500. The jumper supporter 500 may be provided in plural.

[0253] By using the jumper supporter 500, the display device can prevent disconnection of the wire 400 while supporting the optical members 130 and 140. Since the jumper supporter 500 allows the wires 400 provided on one side of the substrate 112 to cross while supporting the optical members 130 and 140, the number of jumper connectors required for the crossing area between the wires 400 can be reduced. Therefore, by reducing the number of jumper connectors, costs can be reduced and process efficiency can be improved.

[0254] The line 400 may include a first line, a second line, a third line, and a fourth line. In this case, the first line may be a data line D1 and D2, the second line may be a scan line S, the third line may be a power line V, and the fourth line may be an output line O. However, the embodiments of the present disclosure are not limited to the above examples, and the first line may be referred to as a scan line S, a power line V, or an output line O, or may be referred to as another line. In addition, the second line may be referred to as a data line D1 or D2, a power line V, or an output line O, or may be referred to as another line. In addition, the third line may be referred to as a data line D1 or D2, a scan line S, or an output line O, or may be referred to as another line. In addition, the fourth line may be referred to as a data line D1 or D2, a scan line S, or a power line V, or may be referred to as another line.

[0255] Various substrate components such as capacitors, resistors, and connectors as well as wires 400, light sources 111, and driving elements 300 may be disposed on substrate 112. Wires 400 may include all wires 400 for electrically connecting light sources 111, driving elements 300, capacitors, resistors, connectors, and the like.

[0256] For the substrate 112 of the display device according to an embodiment, the various components described above may be provided only on the first side facing the display panel 20 among the outer surfaces 251b and 252a, and thus the wire 400 configured to electrically connect the various components may be prevented from being disconnected using the jumper support 500. Therefore, it is not necessary to perform processes on both outer surfaces 251b and 252a of the substrate 112, and thus process efficiency may be improved.

[0257] Fig.13 is a view showing that a jumper supporter in a display device according to an embodiment is electrically connected to a substrate. Fig.14 yes Fig.13 A cross-sectional view of the jumper support and the substrate taken along the direction CC' is shown. Fig.13 The reflective sheet 120 is omitted.

[0258] Reference Fig.13 and Fig.14 , a display device according to an embodiment includes a substrate 112 and a wire 400 provided on the substrate 112 .

[0259] The substrate 112 may include an insulating layer 251 and a conductive layer 252 .

[0260] The substrate 112 may include a first side facing the display panel 20 and a second side opposite to the first side. The substrate 112 may include a plurality of outer surfaces provided at the outermost sides. The outer surface of the substrate 112 may include a first surface 252a and a second surface 251b. The first surface 252a and the second surface 251b may be disposed on opposite sides. The first surface 252a may be a front surface of the substrate 112, and the second surface 251b may be a rear surface of the substrate 112. The first surface 252a may be a front surface of the conductive layer 252, and the second surface 251b may be a rear surface of the insulating layer 251. The first surface 252a may be a side facing the display panel 20.

[0261] The wire 400 may be part of the conductive layer 252. The wire 400 may be formed only on the first side of the substrate 112. That is, in order to form the wire 400, it is sufficient that the conductive layer 252 is formed only on one surface, not on both outer surfaces of the substrate 112. For example, the wire 400 may be formed on the first surface 252a.

[0262] Since the wires 400 are routed only to the first side of the substrate 112, the wires 400 may intersect with each other. When the wires 400 intersect with each other, a single wire 400 may be disconnected. The support member 500 may be used to electrically connect the disconnected wires 400.

[0263] The display device according to an embodiment may include a support 500. The support 500 may be disposed on the substrate 112 to support the optical members 130 and 140. For example, the support 500 may be disposed on a first side of the substrate 112 facing the display panel 20 and the optical members 130 and 140.

[0264] The support member 500 may be electrically connected to the substrate 112. The support member 500 may allow the circuit patterns intersecting each other to be connected without being disconnected. For example, the support member 500 may be disposed in an area where one line 400 and other lines 400 intersect on the first side of the substrate 112, thereby electrically connecting the one line 400 and guiding the other lines 400 to be spaced apart from the one line 400. The support member 500 may be referred to as a jumper support member 500.

[0265] Since the jumper supporter 500 allows the wires 400 provided on one side of the substrate 112 to cross each other while supporting the optical members 130 and 140, it is possible to reduce the number of jumper connectors required on the crossing area between the wires 400. Therefore, by reducing the number of jumper connectors, it is possible to reduce costs and improve process efficiency.

[0266] like Fig.13 As shown, when the data line D intersects the scan line S, the power line V, the output line O, and the timing line 420, the jumper support 500 may allow each line to be connected without being disconnected.

[0267] However, the case where the jumper support 500 connects the line 400 is not limited to the above example. For example, when the scan line S intersects with the data line D, the power line V, the output line O and the timing line 420, the jumper support 500 can allow each line to be connected without disconnecting. Alternatively, when the power line V intersects with the scan line S, the data line D, the output line O and the timing line 420, the jumper support 500 can allow each line to be connected without disconnecting. Alternatively, when the output line O intersects with the scan line S, the data line D, the power line V and the timing line 420, the jumper support 500 can allow each line to be connected without disconnecting. Alternatively, when the timing line 420 intersects with the scan line S, the data line D, the output line O and the power line V, the jumper support 500 can allow each line to be connected without disconnecting.

[0268] Furthermore, even when the scan line S and the power line V extend in parallel directions and the output line O and the data line D extend in directions intersecting the scan line S and the power line V, the jumper supporter 500 may allow each line to be connected without being disconnected.

[0269] Furthermore, even when only one line 400 intersects, the jumper support 500 may allow each line to be connected without being disconnected.

[0270] The line 400 may include a first portion 401 and a second portion 402, respectively. For example, each of the data line D, the scan line S, the power line V, and the output line O may be divided into the first portion 401 and the second portion 402. The first portion 401 and the second portion 402 may be spaced apart from each other on the conductive layer 252 of the substrate 112. The jumper support 500 may electrically connect the first portion 401 and the second portion 402. For example, when the data line D is divided into the first portion 401 and the second portion 402, the jumper support 500 may electrically connect the first portion 401 and the second portion 402 and allow one of the scan line S, the power line V, and the output line O to be spaced apart from the data line D.

[0271] In a display device according to an embodiment, the jumper supporter 500 may include a base 510 mounted on one surface of the substrate 112. For example, the base 510 may be disposed on the insulating layer 251 and the conductive layer 252. Although the base 510 is shown to have a substantially rectangular shape, the shape of the base 510 is not limited thereto.

[0272] The jumper support 500 may further include a support portion 520. The support portion 520 may protrude from the base 510 to support the optical members 130 and 140. The support portion 520 may be formed to have a smaller cross-sectional area in a direction away from the base 510. For example, the support portion 520 may have a conical shape. However, the shape of the support portion 520 is not limited thereto.

[0273] The base 510 and the support portion 520 may be integrally formed. When the base 510 and the support portion 520 are formed as one component, the one component may be referred to as a body.

[0274] The jumper supporter 500 may include a connection portion 530 connected to the conductive layer 252. The connection portion 530 may be connected to a circuit pattern and / or wire 400 provided on the conductive layer 252. For example, the connection portion 530 may be electrically connected to the wire 400 connected to the driving element 300 and / or the light source 111.

[0275] The connection portion 530 may be formed adjacent to the conductive layer 252 to be welded to the conductive layer 252. For example, the connection portion 530 may be formed on the base 510.

[0276] At least one connection portion 530 may be provided. The connection portion 530 may correspond to the number of lines 400 intersecting in the area where the jumper support 500 is provided. For example, when the data line D intersects the scan line S, the power line V, the output line O, and the timing line 420, the jumper support 500 may be connected to the data line D or to the scan line S, the power line V, the output line O, and the timing line 420, thereby allowing each line to be connected without being disconnected. Fig.13 As shown, when the connection portion 530 is connected to the scan line S, the power line V, the output line O, and the timing line 420, four connection portions 530 may be provided.

[0277] The connection portion 530 may be welded to be electrically connected to the conductive layer 252. For example, a first end of the connection portion 530 may be connected to the first portion 401 of the disconnected wire 400 through the first welding portion 601, and a second end of the connection portion 530 may be connected to the second portion 402 of the disconnected wire 400 through the second welding portion 602.

[0278] The first welding portion 601 may be provided on a first end side of the connection portion 530, and the second welding portion 602 may be provided on a second end side of the connection portion 530. The first welding portion 601 may electrically connect the first portion 401 and the connection portion 530, and the second welding portion 602 may electrically connect the second portion 402 and the connection portion 530, thereby electrically connecting the disconnected first portion 401 and second portion 402.

[0279] When the jumper support 500 electrically connects the first portion 401 and the second portion 402 of the wire 400, the jumper support 500 may be spaced apart from the substrate 112. For example, when the jumper support 500 and the insulating layer 251 are spaced apart from each other, a space 700 may be formed between the jumper support 500 and the insulating layer 251. The space 700 may be a region where the first portion 401 and the second portion 402 of the wire 400 are disconnected.

[0280] When the lines 400 intersect each other (refer to Fig.12 and Fig.13 ), one of the wires 400 may be electrically connected by the jumper support 500, and the other 403 of the wires 400 may be disposed in a space 700 formed between the support 500 and the insulating layer 251. Therefore, the one of the wires 400 and the other 403 may be routed without interfering with each other.

[0281] In addition to the relationship between the wires 400, the jumper support 500 can be used for the relationship between the wires 400 and the ground GND. For example, when the wires 400 are routed to the substrate 112, the wires 400 may not bypass the ground GND. At this time, the wires 400 may bypass the ground GND through the jumper support 500.

[0282] In one embodiment, the components including the line 400 and the ground GND may be formed only on one surface 252a of the outer surfaces 252a and 251b of the substrate 112. Therefore, it is not necessary to wire both outer surfaces 252a and 251b of the substrate 112, and only the circuit needs to be wired to one surface 252a of the substrate 112, thereby improving process efficiency.

[0283] Figures 15 to 22 An arrangement relationship between lines in a display device according to an embodiment is shown. Figures 15 to 22 It is schematically shown Fig.12 An enlarged view of area "B" is shown.

[0284] Reference Fig.12 In the display device according to an embodiment, the wires 400 are routed only to the first side of the substrate 112, so a crossover may be generated between the wires 400. At this time, the jumper support 500 may allow the wires 400 to be connected without being disconnected. The display device may include the jumper support 500. The jumper support 500 may be provided in plural. The jumper support 500 may be respectively disposed in each region B.

[0285] Reference Fig.15 , the data line D can intersect with the scan line S. At this time, if Fig.14As shown, the scan line S may be composed of a first portion 401 and a second portion 402, and the first portion 401 and the second portion 402 may be connected via a jumper support 500. The scan line S may be routed to the jumper support 500. For example, the first portion 401 and the second portion 402 of the scan line S may be connected via a connection portion 530.

[0286] The data line D may be spaced apart from the scan line S. The data line D may pass through a space 700 between the jumper supporter 500 and the insulating layer 251. For example, since the jumper supporter 500 is disposed on the conductive layer 252, the space 700 may be formed between the jumper supporter 500 and the insulating layer 251, and the data line D may be wired to the space 700.

[0287] In this case, the jumper supporter 500 configured to connect the first and second portions 401 and 402 of the scan line S and provided to allow the data line D to pass between the insulating layer 251 and the jumper supporter 500 may be referred to as a “first jumper supporter 500 ”.

[0288] However, the embodiments of the present disclosure are not limited thereto. Therefore, the jumper support 500 disposed in the region where the scan line S intersects with the power line V, the region where the scan line S intersects with the output line O, the region where the data line D intersects with the power line V, the region where the data line D intersects with the output line O, and / or the region where the power line V intersects with the output line O may be referred to as a "first jumper support 500".

[0289] Reference Fig.16 , the power line V may cross the scan line S. At this time, the scan line S may be composed of a first portion 401 and a second portion 402, and the first portion 401 and the second portion 402 may be connected through a jumper support 500.
