[0048] The embodiments described in the present disclosure and the configurations shown in the drawings are merely examples of the present disclosure, and various modifications may be made to replace the embodiments and drawings of the present disclosure at the time of filing the present disclosure.

[0049] In the description of the drawings, like reference numerals refer to like elements throughout the description of the drawings.

[0050] The terms used herein are for the purpose of describing the embodiments and are not intended to constrain and / or limit the present disclosure. Unless the context clearly indicates otherwise, the singular expressions here may include plural expressions. In addition, the terms "comprise", "include" and "have" are intended to represent the presence of the features, numbers, steps, operations, elements, parts or combinations thereof described in the present disclosure, and do not exclude the presence or addition of one or more other features, numbers, steps, operations, elements, parts or combinations thereof.

[0051] It will be understood that although the terms first, second, etc. used in the present disclosure can be used to describe various components here, these components should not be limited by these terms. These terms are only used to distinguish one component from another. For example, without departing from the scope of the present disclosure, the first element can be referred to as the second element, and similarly, the second element can be referred to as the first element. The term "and / or" includes one or all of the combinations of a plurality of associated listed items.

[0052] In addition, the meaning of "same" or "equivalent" in the present disclosure may include having similar properties or similarities within a certain range. In addition, "same" or "equivalent" means "substantially the same". It should be understood that the meaning of "substantially the same" refers to a value that falls within the error range in manufacturing or a value that has a difference within a range that is not significant relative to a reference value.

[0053] Terms such as "~component", "~means", "~block", "~member", "~module", etc. may refer to a unit for processing at least one function or action. For example, these terms may at least refer to a process processed by at least one hardware (such as a field programmable gate array (FPGA) and / or an application specific integrated circuit (ASIC)), software stored in a memory, or a processor.

[0054] In the following description, the terms “front,” “rear,” “left,” and “right” are defined based on directions shown in the drawings, but these terms do not necessarily limit the shapes and positions of corresponding components.

[0055] In particular, orientation guides (i.e., "compasses") are provided in the various figures. This guide is intended to provide a consistent sense of direction between the figures, making it easier to determine the orientation of related elements in different figures relative to each other. It should be noted that the terminology used for orientation is selected for convenience and does not limit the orientation of the depicted elements relative to elements that are not part of the depicted system. As just one example, the presentation of an "up" direction does not require that the depicted display be mounted so that the indicated side of the display is oriented upward relative to the ground; for example, if the display is mounted in a portrait orientation rather than the landscape orientation depicted, the "up" direction indicated in the figures would be horizontal relative to the ground. It should also be noted that the use of, for example, "upper" to describe certain features herein does not necessarily indicate a correspondence with the "up" direction of the guide, and the same is true for similar adjectives, as will become clear.

[0056] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings.

[0057] Figure 1 is a perspective view showing a display device according to an embodiment of the present disclosure.

[0058] Reference Figure 1 , the display device 10 is a device that processes an image signal received from the outside and visually displays the processed image.

[0061] like Figure 1 As shown in the embodiment shown in FIG. 1 , the display device 10 may include a main body 11 and a screen 12 , and the screen 12 is provided to display an image I.

[0062] The body 11 may form an appearance of the display device 10, and the body 11 may include components configured to allow the display device 10 to display an image I and perform various functions. Figure 1 The body 11 shown in the illustrated embodiment is in the form of a flat plate, but the shape of the body 11 is not limited thereto. For example, the body 11 may have a curved plate shape.

[0063] The screen 12 may be formed on the front surface of the body 11 and display an image I. For example, the screen 12 may display a static image or a dynamic image. In addition, the screen 12 may display a two-dimensional plane image or a three-dimensional image using binocular parallax of a user.

[0064] The screen 12 may include a display panel for passing or blocking light emitted by a light source device or the like.

[0065] A plurality of pixels P may be formed on the screen 12, and an image I displayed on the screen 12 may be formed by combining lights individually emitted from the plurality of pixels P. For example, the image I may be formed on the screen 12 by combining lights emitted from the plurality of pixels P into a mosaic.

[0068] Each of the plurality of pixels P may emit light with different brightness and different colors by combining red light of the red sub-pixel PR, green light of the green sub-pixel PG, and blue light of the blue sub-pixel PB.

[0069] Figure 2 is an exploded perspective view showing a display device according to an embodiment of the present disclosure. Figure 3 is a cross-sectional view showing a liquid crystal panel included in a display device according to an embodiment of the present disclosure.

[0070] like Figure 2 and Figure 3 As shown in the embodiment shown in , various components configured to generate the image I on the screen 12 may be provided inside the display device 10 .

[0071] For example, the display device 10 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 display device 10 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.

[0072] The light source device 100 may include a point light source configured to emit monochromatic light or white light. In addition, the light source device 100 may refract, reflect, and scatter the light emitted from the point light source so as to convert the light emitted from the point light source into surface light. As described above, the light source device 100 may refract, reflect, and scatter the light emitted from the point light source so as to emit uniform surface light toward the front. The light source device 100 may be referred to as a backlight unit 100.

[0073] The light source device 100 will be described in more detail below.

[0074] The display panel 20 may be provided in front of the light source device 100 , and may block or transmit light emitted from the light source device 100 to form an image I.

[0075] The front surface of the display panel 20 may be formed as shown above. Figure 1 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.

[0076] The display panel may be a liquid crystal panel. Figure 3 As shown in the embodiment shown in , 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.

[0077] 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.

[0078] 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 a specific polarization and block (reflect or absorb) other polarizations. For example, the first polarizing film 21 can transmit polarization in a first direction and block (reflect or absorb) other polarizations. In addition, the second polarizing film 29 can transmit polarization in a second direction and block (reflect or absorb) other polarizations. In this case, the first direction and the second direction can be perpendicular to each other. Therefore, the polarization passing through the first polarizing film 21 can be prevented from passing directly through the second polarizing film 29.

[0079] 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. In addition, 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 corresponds to the above-mentioned pixel P. The area occupied by the red color filter 27R corresponds to the red sub-pixel PR, the area occupied by the green color filter 27G corresponds to the green sub-pixel PG, and the area occupied by the blue color filter 27B corresponds to the blue sub-pixel PB.

[0080] The pixel electrode 23 may be provided on the inner side of the first transparent substrate 22 , and the common electrode 26 may be provided on the inner side of the second transparent substrate 28 .

[0081] The pixel electrode 23 and the common electrode 26 may be formed of a conductive metal material, and the pixel electrode 23 and the common electrode 26 may generate an electric field to change the arrangement of liquid crystal molecules forming the liquid crystal layer 25 .

[0082] The TFT 24 may be provided on the inner side of the first transparent substrate 22. The TFT 24 may be turned on (closed) or off (opened) according to image data provided from the panel driver 30. In addition, an electric field may be formed or removed between the pixel electrode 23 and the common electrode 26 in response to the turning on (closing) or off (opening) of the TFT 24.

[0083] 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 may represent an intermediate state between a solid (crystal) and a liquid. Liquid crystal also exhibits 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. As a result, the polarization passing through the first polarizing film 21 may rotate in the polarization direction while passing through the liquid crystal layer 25, and thus may pass through the second polarizing film 29.

[0084] Back to Figure 2 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 a “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 .

[0086] The panel driver 30 may receive image data and power from the control component 50 and / or the power supply component 60 through the cable 20a. In addition, the panel driver 30 may transmit image data and driving current to the display panel 20 through the cable 20a.

[0087] 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 disposed on the cable 20a. However, the present disclosure is not limited thereto, and the panel driver 30 may be disposed on the display panel 20.

[0088] The control component 50 may include a control circuit configured to control the operation of the display panel 20 and the light source device 100. For example, the control circuit may process a video signal and / or an audio signal received from an external content source. The control circuit may send image data to the display panel 20 and send dimming data to the light source device 100.

[0089] The power supply assembly 60 may include a power supply circuit that supplies 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.

[0090] 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.

The plurality of light sources 111 may be arranged so that a distance between one light source and a light source adjacent thereto is the same or substantially the same.

[0096] The light source 111 may employ an element configured to emit monochromatic light (light of a specific wavelength, such as blue light) or white light (such as a mixture of red light, green light, and blue light) in all directions by receiving power. For example, the light source 111 may include an LED.

[0099] The reflective sheet 120 may be disposed on a front surface 112a of the substrate 112 facing the display panel 20. The reflective sheet 120 may reflect light emitted from the plurality of light sources 111 to the front side or a direction close to the front side.

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

[0101] For example, in 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 may be inserted into the plurality of through holes 120a formed in the reflective sheet 120. Therefore, the substrate 112 of the light source module 110 may be located behind the reflective sheet 120, but the plurality of light sources 111 of the light source module 110 may be located in front of the reflective sheet 120. The plurality of light sources 111 may emit light from the front of the reflective sheet 120.

[0102] The plurality of light sources 111 may emit light in various directions from the front of the reflective sheet 120. Light may be emitted from the light sources 111 toward the diffusion plate 130 and from the light sources 111 toward the reflective sheet 120, which may reflect the light emitted toward the reflective sheet 120 toward the diffusion plate 130.

[0103] The light emitted from the light source 111 passes through various objects, such as the diffusion plate 130, the optical sheet 140, etc. When the light passes through the diffusion plate 130 and the optical sheet 140, some of the incident light may be reflected from the surfaces of the diffusion plate 130 and the optical sheet 140. The reflective sheet 120 may reflect the light reflected by the diffusion plate 130 and the optical sheet 140.

[0104] 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 .

[0105] The diffusion plate 130 may allow light emitted from the plurality of light sources 111 to be diffused inside the diffusion plate 130 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.

[0106] 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.

[0107] The diffusion sheet 141 may diffuse light to achieve uniformity of brightness. Light emitted from the light source 111 may be diffused by the diffusion plate 130 and diffused again by the diffusion sheet 141 included in the optical sheet 140.

[0108] The first and second prism sheets 142 and 143 may increase brightness by focusing light diffused by the diffusion sheet 141. The first and second prism sheets 142 and 143 may include prism patterns having a triangular prism shape, and a plurality of prism patterns may be arranged adjacent to each other to form a plurality of stripe shapes.

[0109] The reflective polarizer 144 may be a polarizing film, and may transmit a portion of incident light and reflect another portion of the light to improve brightness. For example, light polarized in the same or substantially the same direction as the predetermined polarization direction of the reflective polarizer 144 may be transmitted, and light polarized in a direction different from the polarization direction of the reflective polarizer 144 may be reflected. In addition, light reflected by the reflective polarizer 144 may be recycled in the light source device 100, and such light recycling may allow the brightness of the display device 10 to be improved.

[0110] The sheet or film included in the optical sheet 140 is not limited to Figure 4 As shown in the sheet or film, the optical sheet 140 may include more various sheets (such as a protective sheet) or films.

[0111] Figure 5 is a perspective view showing a light source included in a light source device according to an embodiment of the present disclosure. Figure 6 It is shown Figure 5 An exploded perspective view of the light source is shown. Figure 7 yes Figure 5 The light source shown is a side cross-sectional view taken along line AA', in which the optical path of the light source is shown.

[0112] Reference Figures 5 to 7, the light source module 110 includes the plurality of light sources 111. The plurality of light sources 111 may pass through the through holes 120a from the rear of the reflective sheet 120 to protrude to the front of the reflective sheet 120. 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.

[0113] The light source 111 may include an electrical / mechanical structure located in a region defined by the through hole 120a of the reflective sheet 120. For example, each of the plurality of light sources 111 may include an LED 210 and an optical dome 220.

[0114] In order to improve uniformity of surface light emitted by the light source device 100 and contrast through local dimming, the number of light sources 111 may be increased.

[0115] The LED 210 may include a P-type semiconductor and an N-type semiconductor for emitting light through recombination of holes and electrons. In addition, the LED 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.

[0116] LED 210 can convert electrical energy into light energy. In other words, LED 210 can emit light with maximum intensity at a predetermined wavelength of supplied power. For example, LED 210 can emit blue light having a peak at a wavelength representing blue (e.g., a wavelength between 450nm and 495nm).

[0117] The LED 210 may be directly attached to the substrate 112 in a chip-on-board (COB) manner. In other words, the light source 111 may include the LED 210, wherein the LED chip or LED die is directly attached to the substrate 112 without separate packaging.

[0118] In order to reduce the area to be occupied by the LED 210, the LED 210 can be manufactured in a flip chip type, in which the Zener diode is not included. For the flip chip type LED 210, when the LED corresponding to the semiconductor element is bonded to the substrate 112, the electrode pattern of the semiconductor element can 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)).

[0119] Therefore, in an embodiment where metal leads (wires) or a ball grid array are omitted, the light source 111 including the flip chip type LED 210 may be provided in a miniature structure.

[0120] In order to miniaturize the light source 111 , the light source module 110 may be manufactured such that the flip-chip type LED 210 is attached to the substrate 112 in a chip-on-board manner.

[0121] In the above description, the flip chip type LED 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 LED. For example, the light source 111 may include a packaged light emitting diode (LED).

[0122] On the substrate 112 , a feeding line 230 and a feeding pad 240 for supplying power to the LED 210 may be provided.

[0123] On the substrate 112 , a feed line 230 may be provided on the substrate 112 to supply an electrical signal and / or power from the control component 50 and / or the power supply component 60 to the LED 210 .

[0124] like Figure 7 As shown in the embodiment shown in FIG. 1 , the substrate 112 may be formed by alternately stacking non-conductive insulating layers 251 and conductive conductive layers 252 .

[0125] The insulating layer 251 may include a first surface 251 a and a second surface 251 b , and the conductive layer 252 may also include a first surface 252 a and a second surface 252 b . The conductive layer 252 may be deposited on the first surface 251 a of the insulating layer 251 .

[0126] A line or pattern through which power and / or an electrical signal pass may be formed in 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), alloys thereof, etc. The conductive layer 252 may be stacked on one surface (such as the first surface 251a) of the insulating layer 251.

[0127] 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.

[0128] 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 LED 210 through the feeding pad 240. The feeding pad 240 may be formed by exposing the feeding line 230 to the outside.

[0129] A protective layer 253 configured to prevent or inhibit damage due to external impact, damage due to chemical action (eg, corrosion, etc.), and / or damage due to optical action may be formed on the outermost side of the substrate 112. The protective layer 253 may include a photo solder resist (PSR).

[0130] like Figure 7As shown in the embodiment shown in FIG. 2 , the protection layer 253 may cover the feeding line 230 to prevent the feeding line 230 from being exposed to the outside.

[0131] The protective layer 253 may have a window exposing a portion of the feeding line 230 to the outside for electrical contact between the feeding line 230 and the LED 210. The portion of the feeding line 230 exposed to the outside through the window of the protective layer 253 may form a feeding pad 240.

[0132] The feeding pad 240 may be coated with a conductive adhesive material 240a for electrical contact between the feeding line 230 exposed to the outside and the electrode 210a of the LED 210. The conductive adhesive material 240a may be applied to the inner side of the window of the protective layer 253.

[0133] The electrode 210 a of the LED 210 may be in contact with the conductive adhesive material 240 a , and the LED 210 may be electrically connected to the feeding line 230 through the conductive adhesive material 240 a .

[0134] The conductive adhesive material 240a may include, for example, solder having conductivity. However, the present disclosure is not limited thereto, and the conductive adhesive material 240a may alternatively or additionally include, for example, a conductive epoxy resin adhesive.

[0135] Power may be supplied to the LED 210 through the feeding line 230 and the feeding pad 240, and when the power is supplied, the LED 210 may emit light. A pair of feeding pads 240 respectively corresponding to a pair of electrodes 210a provided in the flip chip type LED 210 may be provided.

[0136] The optical dome 220 may cover the LED 210. The optical dome 220 may prevent or suppress damage to the LED 210 caused by an external mechanical action and / or damage to the LED 210 caused by a chemical action.

[0137] 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 arc or a semicircle.

[0138] The optical dome 220 may be formed of silicone or epoxy. For example, molten silicone or epoxy may be discharged onto the LED 210 through a nozzle, and the discharged silicone or epoxy may be cured, thereby forming the optical dome 220.

[0139] Therefore, the shape of the optical dome 220 may vary depending on the viscosity of the liquid silicone or epoxy resin. For example, in an embodiment where 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 2.5 to 3.1 (suitably 2.8), 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.

[0140] The optical dome 220 may be optically transparent or translucent. Light emitted from the LED 210 may be emitted to the outside by passing through the optical dome 220.

[0141] In this case, the dome-shaped optical dome 220 may refract light like a lens. For example, light emitted from the LED 210 may be refracted by the optical dome 220 and thus may be dispersed.

[0142] As described above, the optical dome 220 may protect the LED 210 from external mechanical, chemical, or electrical effects and disperse light emitted from the LED 210 .

[0143] An anti-static member (not shown) may be formed adjacent to the optical dome 220 to protect the LED 210 from electrostatic discharge. The anti-static member (not shown) may absorb an electric shock caused by electrostatic discharge generated near the optical dome 220.

[0144] Reference Figure 7 , the light source module 110 may include an insulating layer 251 having a non-conductive property, a conductive layer 252 having a conductive property and stacked on a front surface of the insulating layer 251 and including a feed line 230, and a protective layer 253 having a non-conductive property and stacked on a front surface 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.

[0145] The LED 210 may be disposed on the protective layer 253. More specifically, the LED 210 may be disposed on the front surface 112a of the substrate 112 to cover the window formed in the protective layer 253.

[0146] A pair of feeding pads 240 may be formed in the conductive layer 252 and connected to the feeding line 230. The pair of feeding pads 240 may be electrically connected to the LED 210 through a window formed in the protective layer 253. The pair of feeding pads 240 may be disposed to be spaced apart from each other.

[0147] The light source module 110 may include a reflective auxiliary layer 260 .

[0148] exist Figure 7 In the illustrated embodiment, the reflection auxiliary layer 260 is formed between the pair of feeding pads 240 together with the protective layer 253. Therefore, the defect rate due to the asymmetry of the sizes of the pair of feeding pads 240 can be reduced.

[0149] The LED 210 may include a distributed Bragg reflector (DBR) layer 211 .

[0150] The DBR layer 211 may be a multilayer reflector including two materials having different refractive indices. Due to the difference in the refractive index of each material, Fresnel reflection occurs at the interface of the DBR layer 211. Therefore, light incident on the DBR layer may be reflected at a wide angle range, and the light directing angle of the LED 210 may be provided at about 165 degrees or more.

[0151] The light emitted from the LED 210 may be reflected by the DBR layer 211 and then reflected again by the reflective auxiliary layer 260. With such a configuration, optical loss of the light traveling to the space between the pair of feeding pads 240 may be prevented.

[0152] Specifically, in an embodiment where the reflection auxiliary layer 260 is formed of a material having a higher reflectivity than the insulating layer 251 , the reflection auxiliary layer 260 covering the front of the insulating layer 251 can minimize optical loss occurring when light is guided to the rear side of the LED 210 and absorbed by the insulating layer 251 .

[0153] Figure 8 is a view showing a plurality of light sources divided into a plurality of dimming blocks of a display device according to an embodiment of the present disclosure. Fig. 9 is a control block diagram of a display device according to an embodiment of the present disclosure.

[0154] The display device 10 may perform local dimming to change the brightness of light of each area of ​​the light source device 100 associated with an output image, thereby improving power consumption while increasing contrast.

[0155] For example, the display device 10 can reduce the brightness 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 increase the brightness 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.

[0156] The display device 10 divides the light source device 100 into a plurality of blocks and independently controls the current of each block according to the input image. The image transmission of the display device 10 is performed by a method of driving by local dimming of each frame, and the driving of the current can be adjusted according to the number of divided blocks of the light source 111 in the light source device 100.

[0157] 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 increasing the supply current to the dimming block corresponding to the bright area of ​​the input image.

[0158] 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, Figure 8 As shown in the embodiment shown in FIG. 1 , a total of sixty dimming blocks 200 may be provided as five rows and twelve columns. However, the number of dimming blocks 200 is not limited to the above example.

[0159] Reference Figure 8 , 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 or substantially the same brightness.

[0160] Furthermore, the light source apparatus 100 may supply different driving currents to the light sources 111 belonging to different dimming blocks 200 according to the dimming data, and the light sources 111 belonging to different dimming blocks 200 may emit light having different brightness.

[0161] Each of the plurality of dimming blocks 200 may include, for example, N×M light sources arranged in an N×M matrix (N and M are natural numbers). The N×M matrix refers to a matrix having N rows and M columns.

[0162] In an embodiment where each light source 111 includes an LED, each of the plurality of dimming blocks 200 may include N×M LEDs.

[0163] The plurality of dimming blocks 200 may be disposed on the substrate 112. That is, N×M×B LEDs may be disposed on the substrate 112, where B is the number of the plurality of dimming blocks 200 (B is a natural number).

[0164] like Fig. 9 As shown in the embodiment shown in , 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 .

[0165] The content receiver 80 may include a receiving terminal 81 and a tuner 82 , the receiving terminal 81 being provided to receive content including a video signal and / or an audio signal from a content source.

[0166] The receiving terminal 81 may receive video signals and audio signals from a content source via a cable.

[0167] 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.

[0168] 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.

[0169] The image processor 90 includes 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.

[0170] The memory 92 may be a non-transitory computer-readable memory. The memory 92 may store programs and data for processing video signals and / or audio signals. The memory 92 may temporarily memorize or store data generated in the processing of video signals and / or audio signals.

[0171] 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.

[0172] The image processor 90 may generate image data and dimming data from the video signal acquired by 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.

[0173] The image data may include information on the intensity of light transmitted by each of the plurality of pixels (or the 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.

[0174] 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 vary according to the analog image signal.

[0175] The panel driver 30 may include a timing controller, a data driver, and a scan driver.

[0176] 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 operation of the data driver, respectively.

[0177] The scan driver may receive a scan control signal from the timing controller. The scan driver may input and activate any one of the multiple rows in the display panel 20 in response to the scan control signal. In other words, the scan driver may transform the pixels included in one row of the multiple pixels arranged in multiple rows and columns into a state capable of receiving an analog image signal. In this case, pixels other than the pixels activated by the scan driver input may not receive the analog image signal.

[0178] 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 in response 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 a row activated by the scan driver input. In this case, the pixels activated by the scan driver input may receive the analog image signal. The optical properties (e.g., transmittance) of the pixels activated by the input may be changed according to the received analog image signal.

[0179] 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.

[0180] In addition, the dimming data may include information on the intensity of light emitted from each of the plurality of light sources (or the 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.

[0181] The light source device 100 may include a plurality of light sources 111 that emit light. The plurality of light sources 111 may be arranged in a matrix form. In other words, the plurality of light sources 111 may be arranged in a plurality of rows and columns.

[0182] The light source device 100 may be divided into a plurality of dimming blocks 200. In addition, each of the plurality of dimming blocks 200 may include at least one light source.

[0183] The light source device 100 may scatter the light emitted from the plurality of light sources 111, thereby outputting surface light. The display panel 20 may include a plurality of pixels, and may control the plurality of pixels to allow the plurality of pixels to individually transmit or block light. An image may be formed by light passing through each of the plurality of pixels.

[0184] In this case, in order to make the dark part of the image darker, the light source device 100 may turn off the light source corresponding to the dark part of the image. Therefore, the dark part of the image may be made darker, and the contrast of the image may be improved.

[0185] In this way, the operation of the light source device 100 controlling the plurality of light sources to emit light in the area corresponding to the bright part of the image and controlling the plurality of light sources not to emit light in the area corresponding to the dark part of the image is hereinafter referred to as “local dimming”.

[0186] 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, such as Figure 8 As shown in the embodiment shown in FIG. Figure 8 A total of sixty dimming blocks with five rows and twelve columns are shown, but the number and arrangement of the dimming blocks are not limited to Figure 8 Those shown in .

[0187] 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 included in the same dimming block, and the light sources included in the same dimming block may emit light of the same or substantially the same brightness. For example, the light sources belonging to the same dimming block may be connected in series, and thus the same driving current may be supplied to the light sources belonging to the same dimming block.

[0188] In addition, the light source device 100 may further include a plurality of driving elements 300 (hereinafter referred to as Fig.10 and Fig.11 ), which controls the driving current supplied to the light source included in each of the plurality of dimming blocks 200. Each driving element 300 may be provided to correspond to at least one dimming block 200. In other words, the driving element 300 may drive the dimming blocks 200 individually.

[0189] As such, in an embodiment in which light sources belonging to a dimming block are connected in series to each other, the light sources included in the dimming block operate as one part and form the light source block as one party.

[0190] Therefore, hereinafter, “supplying a driving current to a dimming block” may be understood as “supplying a driving current to a light source included in the dimming block”.

[0191] Despite Figure 8 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 Figure 8 Those shown in .

[0192] 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 by the light source included in each of the plurality of dimming blocks 200.

[0193] The image processor 90 may obtain dimming data from image data decoded from the video signal.

[0194] 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 into a plurality of image blocks based on the image data. The number of the plurality of image blocks may be the same as the number of the plurality of dimming blocks 200, and each of the plurality of image blocks may correspond to each of the plurality of dimming blocks 200.

[0195] 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.

[0196] 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.

[0197] Each image block may include a plurality of pixels, and the image data of the 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.

[0198] The image processor 90 may determine the maximum value among the brightness values ​​of the pixels 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 determine 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 determine 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.

[0199] The image processor 90 may generate dimming data by combining the brightness values ​​of the plurality of dimming blocks 200 .

[0200] 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 dimming block in the plurality of dimming blocks 200 or information about the brightness of the light sources included in the plurality of dimming blocks 200.

[0201] The dimming driver 170 may convert the dimming data, which is a digital signal, into an analog driving current.

[0202] The dimming driver 170 may provide analog dimming signals to the driving elements 300 respectively corresponding to the dimming blocks 200 in sequence, for example, in an active matrix manner.

[0203] The dimming driver 170 may include a connector (not shown). The dimming driver 170 may transmit the scan signal, the data signal, and the power signal to the driving element 300 through the connector.

[0204] The plurality of dimming blocks 200 may be divided into a plurality of groups. Dimming blocks belonging to the same group may be supplied with driving currents at the same time, and dimming blocks belonging to different groups may be supplied with driving currents 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. Then, the dimming driver 170 may activate a dimming block belonging to another group and provide an analog dimming signal to the activated dimming block.

[0205] For example, dimming blocks in the same row may belong to the same group, and dimming blocks in different rows may belong to different groups, but the method of dividing the groups is not limited thereto. The dimming driver 170 may activate a dimming block belonging to any one group and provide an analog dimming signal to the activated dimming block. Then, the dimming driver 170 may input activate a dimming block belonging to another row and provide an analog dimming signal to the input activated dimming block.

[0206] The driving circuit of each dimming block 200 may 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 may be allowed to emit light by the analog driving current. The light sources belonging to the same dimming block may emit light having the same or substantially the same intensity according to the dimming data. In addition, the light sources belonging to different dimming blocks may emit light having different intensities according to the dimming data.

[0207] Fig.10 1 is a view showing an example of a connection structure of a dimming driver 170 , a driving element 300 , and a dimming block 200 in a display device according to an embodiment of the present disclosure, and a line arrangement in a light source device.

[0210] Among the plurality of light sources 111 connected in series included in one dimming block 200 , the first light source 111 in the series connection may be connected to a power line V to receive power (driving voltage VLED), and the last light source 111 in the series connection may be connected to a driving element 300 .

[0211] The driving element 300 may receive an analog dimming signal from the dimming driver 170 during input activation of the dimming driver 170 and store the received analog dimming signal. In addition, the driving element 300 may supply a driving current corresponding to the stored analog dimming signal to the plurality of light sources (LEDs) 111 during input deactivation.

[0216] The plurality of driving elements 300 may include circuits having various topologies to implement an active matrix driving method.

[0217] For example, each of the plurality of driving elements 300 may include a single capacitor dual transistor (1C2T) topology circuit. 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 compensate for the body effect of the driving transistor.

[0218] The driving element 300 may be provided in a single chip in which the driving circuit is integrated. In other words, the driving circuit may be integrated in a single semiconductor chip.

[0219] 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 .

[0220] In addition, the dimming driver 170 may transmit a timing signal corresponding to the emission timing of the plurality of dimming blocks 200 to the plurality of driving elements 300 through the scan line S.

[0221] 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.

[0222] exist Fig.10 For the sake of drawing, only a relatively small number of dimming blocks 200 are shown. The display device 10 may include more dimming blocks 200 for local dimming, driving elements 300, and data lines D1 and D2, scan lines S and power lines V, and lines connecting the dimming blocks 200 and the driving elements 300.

[0223] Therefore, it is desirable to simplify the arrangement of the data lines D1 and D2 , the scan lines S, and the power lines V on the substrate 112 .

[0224] In one embodiment, the line may include data lines D1 and D2, a scan line S, a power line V, a line connecting 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"), but the type of the 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 T").

[0225] The plurality of dimming blocks 200 may be arranged in a matrix form on the front surface 112a of the substrate 112 of the light source device 100, and each of the plurality of dimming blocks 200 may include a plurality of light sources 111.

[0227] In one embodiment, a plurality of dimming blocks 200 included in two rows adjacent to each other among the plurality of dimming blocks 200 may be electrically connected to a power line V extending between the two rows.

[0228] According to one embodiment, the power lines can be efficiently arranged by providing only one power line V between two rows.

[0229] In one embodiment, the plurality of driving elements 300 may be alternately disposed between adjacent columns in a matrix formed by the plurality of dimming blocks 200 .

[0232] In one embodiment, among the plurality of driving elements 300 , the driving elements 300 disposed in different columns may be electrically connected to each other through the timing line T.

[0233] According to one embodiment, each driving element 300 may be connected in series with its adjacent driving element 300 via a timing line T, which allows timing signals to be shared with each other, thereby reducing the number of data lines D1 and D2 and / or the number of scan lines S.

[0234] exist Fig.10 , a line arrangement of the light source device 100 according to a combination of all the above embodiments is shown. However, the light source device 100 according to an embodiment may include a line arrangement implemented by each of the above embodiments, a combination of some of the above embodiments, or a combination of all of the above embodiments.

[0235] Fig.11 is a view showing a line arrangement in a display device according to an embodiment of the present disclosure. Fig.11 1 is a plan view showing a first side (eg, first surface 112a) of the substrate 112. In other words, Fig.11 Components electrically connected on a first side of substrate 112 are shown.

[0236] Reference Fig.11 , the display device includes at least one driving element 300 and at least one line 400 .

[0237] The at least one driving element 300 may be provided as a plurality of driving elements. The plurality of driving elements 300 may include a first driving element 310 and a second driving element 320 .

[0238] The at least one line 400 may be connected between the dimming driver 170, the first and second driving elements 310 and 320, and the light source 111 to transmit signals. The at least one line 400 may transmit power from the dimming driver 170 including the connector to the light source 111 and the driving element 300.

[0239] The dimming driver 170 may be disposed on the light source substrate 112 , or may be disposed on a separate substrate other than the light source substrate 112 .

[0240] The at least one line 400 may be provided as a plurality of lines. The plurality of lines 400 may include at least one data line D, at least one scan line S, a power line V, a timing line T, and at least one output line O. The at least one line 400 may include at least a portion of the feed pad 240. The plurality of lines 400 are not limited to only the above-mentioned lines, but may include various types of lines wired in the light source substrate 112.

[0241] The at least one data line may include a first data line D1 and a second data line D2, through which a data signal from the dimming driver 170 is transmitted to the first driving element 310, and through which a data signal from the dimming driver 170 is transmitted to the second driving element 320. The first data line D1 and the second data line D2 may be provided as a plurality of first data lines and a plurality of second data lines.

[0242] The at least one scan line S may include a first scan line S1 and a second scan line S2, a scan signal from the dimming driver 170 is transmitted to the first driving element 310 through the first scan line S1, and a scan signal from the dimming driver 170 is transmitted to the second driving element 320 through the second scan line S2. The first scan line S1 and the second scan line S2 may be provided as a plurality of first scan lines and a plurality of second scan lines.

[0243] The at least one output line O may allow a data signal from the driving element 300 to be transmitted to the light source 111. The number of the output lines O may vary according to the scan signal and the data signal transmitted from the dimming driver 170 to the driving element 300.

[0244] The at least one output line O may include a first output line O1 through which a data signal from the first driving element 310 is transmitted to the first light source 111 , and a second output line O2 through which a data signal from the second driving element 320 is transmitted to the second light source 111 .

[0245] The numbers of the data lines D, the scan lines S, and the output lines O are not limited to the above examples.

[0246] The line 400 may be provided on one side of the substrate 112. For example, the line 400 may be formed only on one surface forming the outer side of the substrate 112, rather than on both surfaces forming the outer side of the substrate 112. For example, the line 400 may be provided on the front surface 112a of the substrate 112. The front surface 112a may be a surface of the substrate 112 facing the display panel.

[0247] In an embodiment where the lines 400 are formed only on the front surface 112a of the substrate 112, the lines 400 may cross each other. The lines 400 may be formed in multiple areas (eg Fig.11 For example, the data line D1 or D2 for transmitting the data signal from the dimming driver 170 to the driving element 300 may cross with the scan line S1 or S2 for transmitting the scan signal from the dimming driver 170 to the driving element 300, or the data lines D1 and D2 may cross with the power line V for supplying power (driving voltage VLED) to the light source 111 and the driving element 300, or the scan line S1 or S2 may cross with the power line V. In addition, one of the output line O, the power line V, the scan line S, and the data line D may be subjected to crossing.

[0248] For example, the first data line D1, the first scan line S1, and the power line V through which the data signal, the scan signal, or the power is transmitted to the first driving element 310 may cross the first output line O1 through which the data signal is transmitted from the first driving element 310 to the first light source 111. In addition, the second data line D2, the second scan line S2, and the power line V through which the data signal, the scan signal, or the power is transmitted to the second driving element 320 may cross the second output line O2 through which the data signal is transmitted 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 cross the line 400 connected to the second driving element 320.

[0249] When the wires 400 cross each other, one of the wires 400 may be disconnected. Therefore, it is preferable to prevent the wires 400 from being disconnected so that the wires 400 can each remain electrically connected. In addition, the wires 400 may pass through the ground GND on one surface of the substrate 112, and even in this case, it is preferable to prevent the wires 400 from being disconnected.

[0250] According to one embodiment, the display device may include a jumper connector 500. For example, the backlight unit 100 may include the jumper connector 500. The display device may prevent the wire 400 from being disconnected using the jumper connector 500. The jumper connector 500 may be provided as a plurality of jumper connectors. Details are described below.

[0251] The line 400 may include a first line, a second line, a third line, and a fourth line. For example, the first line may be a data line D, 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, without limitation to the above examples, the first line may be a scan line S, a power line V, or an output line O, or may be another line. In addition, the second line may be a data line D, a power line V, or an output line O, or may be another line. In addition, the third line may be a data line D, a scan line S, or an output line O, or may be another line. In addition, the fourth line may be a data line D, a scan line S, a power line V, or may be another line.

[0252] In addition, although not shown, various board components such as capacitors, resistors, and connectors as well as wires 400, the light source 111, and the driving element 300 may be provided on the substrate 112. The wires 400 may include all wires 400 for electrically connecting the light source 111, the driving element 300, the capacitors, resistors, connectors, etc. described above.

[0253] In an embodiment in which the substrate 112 of the display device according to an embodiment may have the above-mentioned various components disposed only on the first surface facing the display panel 20 among the outer surfaces, the jumper connector 500 may be used to prevent disconnection of the wire 400 that electrically connects the components to each other. Therefore, it is not necessary to process both sides of the outer surface of the substrate 112 to avoid disconnection, resulting in improved process efficiency.

[0254] Figure 12 to Figure 14 1 is a view showing a state in which a jumper connector 500 is electrically connected to a substrate 112 in a display device according to an embodiment of the present disclosure.

[0255] Reference Figure 12 to Figure 14 , a display device according to an embodiment includes a substrate 112 , a jumper connector 500 electrically connected to the substrate 112 , and a wire 400 provided on the substrate 112 .

[0256] The substrate 112 includes an insulating layer 251 and a conductive layer 252. In addition, the substrate 112 may include a protective layer ( Figure 6 and Figure 7 Since the protective layer 253 does not need to be formed in the area where the jumper connector 500 is installed, Figure 12 to Figure 14 The illustration thereof is omitted.

[0257] The substrate 112 includes a plurality of layers and may include a plurality of outer surfaces provided on the outer sides of the plurality of layers. The substrate 112 may include a first side facing the display panel and a second side opposite to the first side. 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 surface facing the display panel.

[0258] The wire 400 may be a 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 in the substrate 112, the conductive layer 252 may be formed only on one side of the substrate 112, rather than on both sides of the outer surface. For example, the wire 400 may be formed on the first surface 252a.

[0259] In the embodiment shown here, since the wires 400 are routed only on the first side of the substrate 112 , the wires 400 may cross each other.

[0260] When the lines 400 cross each other, one of the lines 400 may be disconnected. In order to electrically connect the disconnected lines 400, a jumper connector 500 may be used. The jumper connector 500 may be disposed in a portion or region (which may be referred to as a cross region) where the lines 400 cross each other. For example, when the data line D and the scan line S cross each other, since one of the lines 400 may be disconnected, the jumper connector 500 may be disposed in a portion or region where the data line D and the scan line S cross each other.

[0261] The jumper connector 500 electrically connects one of the lines 400 (which may be referred to as a first line corresponding to the jumper connector 500 or a connected line), and guides another line 403 of the lines 400 (which may be referred to as a second line corresponding to the jumper connector 500 or a guided line) to be spaced apart from the first line of the lines 400. For example, the jumper connector 500 may electrically connect the data line D while guiding the scan line S to be spaced apart from the data line D, or may electrically connect the scan line S while guiding the data line D to be spaced apart from the scan line S.

[0262] Each line 400 may include a first portion 401 and a second portion 402. 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 in the conductive layer 252 of the substrate 112. The jumper connector 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 connector 500 may electrically connect the first portion 401 and the second portion 402, and may space one of the scan line S, the power line V, and the output line O from the data line D.

[0263] The jumper connector 500 may include a body 510 and a wire portion 520 formed in the body 510 .

[0264] The wire portion 520 may electrically connect one of the wires 400. For example, when the wire 400 is disconnected from the intersection, the wire portion 520 may connect the disconnected wire 400.

[0265] The wire portion 520 may include a first point 521 connected to the first portion 401 of the disconnected wire 400 , a second point 522 connected to the second portion 402 of the disconnected wire 400 , and a connection portion 523 connecting the first point 521 and the second point 522 .

[0266] The circuit line may be formed in the wire portion 520 and the connection portion 523. The connection portion 523 may include a first connection portion 523a, a second connection portion 523b, and a third connection portion 523c. The first connection portion 523a may be connected to the first point 521, the second connection portion 523b may be connected to the second point 522, and the third connection portion 523c may connect the first connection portion 523a and the second connection portion 523b. Therefore, the first connection portion 523a, the second connection portion 523b, and the third connection portion 523c may be connected to each other, thereby allowing the first portion 401 and the second portion 402 of the line 400 to be electrically connected to each other through the connection portion 523.

[0267] exist Fig.12 In the illustrated embodiment, the first connection portion 523a and the second connection portion 523b are formed substantially parallel to each other in opposite sides of the body 510, and the third connection portion 523c is formed substantially perpendicular to the first connection portion 523a and the second connection portion 523b. However, the connection portion 523 is not limited to the shapes exemplified above, and may be provided in various shapes and numbers as long as they can collectively connect the first portion 401 and the second portion 402 of the wire 400.

[0268] The jumper connector 500 can connect one end of the first part 401 to one end of the second part 402. Fig.12 As shown in the embodiment shown in , the jumper connector 500 can be moved toward the substrate 112 from the front side and electrically connected to the wire 400.

[0269] The first point 521 of the wire portion 520 may be welded to the first portion 401 of the wire 400, and the second point 522 of the wire portion 520 may be welded to the second portion 402 of the wire 400. For example, the first welding portion 601 may be provided at the first point 521 and the second point 522, and the second welding portion 602 may be provided at the one end of the first portion 401 and the one end of the second portion 402. Fig.13 and Fig.14 As shown in the embodiment shown in , the first welding portion 601 and the second welding portion 602 can be welded to form an electrical connection 603.

[0270] Therefore, since the first portion 401 of the wire 400 and the wire portion 520 are electrically connected and the second portion 402 of the wire 400 and the wire portion 520 are electrically connected, the first portion 401 and the second portion 402 are electrically connected to each other, and thus an electrical signal may flow through the wire 400 .

[0271] When the jumper connector 500 electrically connects the first portion 401 and the second portion 402 of the wire 400, the jumper connector 500 may be spaced apart from the substrate 112. For example, the jumper connector 500 and the insulating layer 251 may be spaced apart from each other so that a space 700 may be provided between the jumper connector 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 disposed on opposite sides of the space 700 and are thereby disconnected from each other.

[0272] When the lines 400 cross each other (see Fig.11 ), one of the wires 400 may be electrically connected by the jumper connector 500, and the other wire 403 of the wires 400 may be disposed in a space 700 formed between the jumper connector 500 and the insulating layer 251. Therefore, the one of the wires 400 and the other wire 403 may be wired without interfering with each other.

[0273] The jumper connector 500 need not be limited to use with respect to the line 400, but can also be used with respect to the ground GND. For example, when the line 400 is routed to the substrate 112, it is not desirable for the line 400 to bypass the ground GND. In this case, the line 400 can be routed above the ground GND through the jumper connector 500.

[0274] According to an embodiment, components including the line 400 and the ground GND may be formed only on one side of the outer surface of the substrate 112. Therefore, wiring of components may be performed only on one surface of the substrate 112 rather than on both surfaces of the substrate 112, resulting in improved processing efficiency.

[0275] like Fig.13 and Fig.14 As shown in the embodiment shown in FIG, since the jumper connector 500 can be formed in black, the reflective sheet 120 having a white-based color can be provided on the front side of the jumper connector 500 to cover the jumper connector 500, thereby preventing "Mura" (unevenness). The reflective sheet 120 can be attached to the jumper connector 500. For example, the adhesive surface 121a of the reflective sheet 120 can be bonded to the front surface 511 of the body 510 of the jumper connector 500.

[0276] In this case, there may be a space 120c formed by air between the reflection sheet 120 and the jumper connector 500 (see FIG. Fig.13), which separates the reflective sheet 120 and the jumper connector 500 and can prevent adhesion. Therefore, the adhesive portion 121 of the reflective sheet 120 may be provided with an air exhaust portion 120b so that the air in the space 120c between the reflective sheet 120 and the jumper connector 500 can be exhausted to eliminate the space 120c and stably bond the reflective sheet 120 and the jumper connector 500 (see Fig.14 ).

[0277] The air discharge portion 120b may have various shapes. For example, the air discharge portion 120b may have a slit shape. The air discharge portion 120b is not limited to the above example as long as it is formed on the adhesive portion 121 of the reflective sheet 120.

[0278] The adhesive portion 121 of the reflective sheet 120 may be provided in a region corresponding to the jumper connector 500. For example, the adhesive portion 121 may be formed to correspond to the front surface 511 of the body 510.

[0279] Figures 15 to 22 is a view showing an arrangement relationship between lines in a display device according to an embodiment of the present disclosure, in which Fig.11 The intersection or intersection area "A" is shown.

[0280] Reference Fig.11 In an embodiment where the wires 400 are routed only on the first side of the substrate 112 in the display device, crossing may occur between the wires 400. In this case, the jumper connector 500 may allow the wires 400 to be connected without disconnection. The display device may include a jumper connector 500. The jumper connector 500 may be a plurality of jumper connectors. The jumper connector 500 may be disposed in a corresponding region A.

[0281] Reference Fig.15 , the data line D and the scan line S may cross each other. In this case, Figure 12 to Figure 14 As shown in the embodiment shown in FIG. 1 , the scan line S may include a first portion 401 and a second portion 402, and the first portion 401 and the second portion 402 may be connected to each other through a jumper connector 500. The scan line S may be wired in the jumper connector 500. For example, the first portion 401 and the second portion 402 of the scan line S may be connected to each other through a wire portion 520.

[0282] 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 connector 500 and the insulating layer 251. For example, in an embodiment where the jumper connector 500 is disposed on the conductive layer 252, the space 700 may be formed between the jumper connector 500 and the insulating layer, and the data line D may be wired in the space 700.

[0283] In this case, the jumper connector 500 connecting the first portion 401 and the second portion 402 of the scan line S while allowing the data line D to pass between the jumper connector 500 and the insulating layer 251 may be referred to as a first jumper connector 500 .

[0284] Reference Fig.16 , the power line V and the scan line S may cross each other.
