The light source device100may include a point light source configured to emit monochromatic light or white light. The light source device100may refract, reflect, and scatter light in order to convert light, which is emitted from the point light source, into uniform surface light. As mentioned above, the light source device100may refract, reflect, and scatter light emitted from the point light source, thereby emitting uniform surface light toward the front side. The light source device100may be referred to as a back light unit100.

The light source device100is described in more detail below.

The display panel20may be provided in front of the light source device100and block or transmit light emitted from the light source device100to form the image I.

A front surface of the display panel20may form the screen12of the display apparatus10described above, and the display panel20may form the plurality of pixels P. In the display panel20, the plurality of pixels P may independently block or transmit light from the light source device100. Further, the light transmitted through the plurality of pixels P may form the image I displayed on the screen12.

For example, as shown inFIG.3, the display panel20may include a first polarizing film21, a first transparent substrate22, a pixel electrode23, a thin film transistor (TFT)24, a liquid crystal layer25, a common electrode26, a color filter27, a second transparent substrate28, and a second polarizing film29.

The first transparent substrate22and the second transparent substrate28may fixedly support the pixel electrode23, the TFT24, the liquid crystal layer25, the common electrode26, and the color filter27. The first and second transparent substrates22and28may be formed of tempered glass or transparent resin.

The first polarizing film21and the second polarizing film29may be provided on the outside of the first and second transparent substrates22and28. Each of the first polarizing film21and the second polarizing film29may transmit specific polarized light and block (reflect or absorb) other polarized light. For example, the first polarizing film21may transmit light polarized in a first direction and block (reflect or absorb) other polarized light. In addition, the second polarizing film29may transmit light polarized in a second direction and block (reflect or absorb) other polarized light. In this case, the first direction and the second direction may be perpendicular to each other. Accordingly, polarized light passing through the first polarizing film21may not directly pass through the second polarizing film29.

The color filter27may be provided on an inner side of the second transparent substrate28. The color filter27may include a red filter27R transmitting red light, a green filter27G transmitting green light, and a blue filter27B transmitting blue light.

The TFT24may be provided in an inner side of the second transparent substrate28. The TFT24may be turned on (closed) or turned off (open) by image data provided from a panel driver30. Further, an electric field may be formed or removed between the pixel electrode23and the common electrode26depending on whether the TFT24is turned on (closed) or turned off (open).

The liquid crystal layer25may be formed between the pixel electrode23and the common electrode26, and the liquid crystal layer25may be filled with liquid crystal molecules25a. Liquid crystals represent an intermediate state between a solid (crystal) and a liquid. Liquid crystals may exhibit optical properties according to changes in an electric field. For example, in the liquid crystal, the orientation of molecules forming the liquid crystal may change according to a change in an electric field. As a result, the optical properties of the liquid crystal layer25may vary depending on the presence or absence of the electric field passing through the liquid crystal layer25. For example, the liquid crystal layer25may rotate a polarization direction of light with respect to an optical axis depending on the presence or absence of an electric field. Accordingly, the polarization direction of the polarized light passing through the first polarizing film21may be rotated while passing through the liquid crystal layer25, and the polarized light may pass through the second polarizing film29.

A cable20aconfigured to transmit image data to the display panel20, and a display driver integrated circuit (DDI) (hereinafter referred to as ‘panel driver’)30configured to process digital image data and output an analog image signal may be provided at one side of the display panel20.

In addition, the cable20aand the panel driver30may be integrally implemented as a film cable, a chip on film (COF), or a tape carrier package (TCP). In other words, the panel driver30may be arranged on the cable20b. However, embodiments of the disclosure are not limited thereto, and the panel driver30may be arranged on the display panel20.

The control assembly50may include a control circuit configured to control an operation of the display panel20and the light source device100.

For example, the power circuit may include a capacitor, a coil, a resistance element, a processor, and a power circuit board on which the capacitor, the coil, the resistance element, and the processor are mounted. Further, the control circuit may include a memory, a processor, and a control circuit board on which the memory and the processor are mounted.

The light source device100will be described.

FIG.4is an exploded-perspective view of a light source device included in the display apparatus according to an embodiment.FIG.5is a view illustrating a combination of a light source module and a reflective sheet included in the light source device shown inFIG.4.

Referring toFIGS.4and5, the light source device100may include a light source module110configured to generate light, a reflective sheet120configured to reflect light, a diffuser plate130configured to uniformly diffuse light, and an optical sheet140configured to improve a luminance of light that is emitted.

The light source module110may include a plurality of light sources111configured to emit light, and a light source substrate112provided to support/fix the plurality of light sources111. The light source substrate112may be referred to as a substrate112.

The plurality of light sources111may be disposed in a predetermined pattern to emit light with the uniform luminance. The plurality of light sources111may be disposed in such a way that a distance between one light source and light sources adjacent thereto is the same.

The light source111may employ an element configured to emit monochromatic light (light of a specific wavelength, for example, blue light) or white light (for example, light of a mixture of red light, green light, and blue light) in various directions by receiving power. For example, the light source111may include a light emitting diode (LED).

The substrate112may fix the plurality of light sources111to prevent a change in the position of the light source111. Further, the substrate112may supply power, which is for the light source111to emit light, to the light source111.

The substrate112may fix the plurality of light sources111and may be configured with synthetic resin or tempered glass or a printed circuit board (PCB) on which a conductive power supply line for supplying power to the light source111is formed.

The substrate112may be composed of an insulation layer formed of synthetic resin or tempered glass. A circuit may be printed on one side of the substrate112. For example, a circuit pattern and/or line may be formed on a front surface of the substrate112facing the display panel20.

The display apparatus according to an embodiment may further include a supporter500. The supporter500may be installed on the substrate112. The supporter500may be mounted on an upper surface of the substrate112by soldering. The supporter500may be provided in plurality. The plurality of supporters500may be disposed between the substrate112and the optical members130and140. The plurality of supporters500may be mounted on the upper surface of the substrate112to support the optical members130and140.

The supporter500may be provided to maintain optical characteristics of the light source device100by maintaining an optical distance (OD) between the light source111and the diffuser plate130and/or the optical sheet140. The supporter500may be provided at a length capable of maintaining the optical characteristics of the light source device100.

The supporter500may be a jumper supporter500that is disposed in a region, in which circuit patterns intersect each other, so as to allow the circuit patterns to be connected to each other without interference. For example, the jumper supporter500may be disposed in a region, in which the plurality of lines400intersects each other, so as to allow the plurality of lines400to be connected to each other without interference. Because the jumper supporter500allows the lines400provided on one side of the substrate112to intersect each other while supporting the optical members130and140, it is possible to reduce the number of jumper connectors that is needed in the region where the lines intersect. Therefore, by reducing the number of jumper connectors, it is possible to reduce costs and improve process efficiency. Details about the jumper supporter500will be described later.

The reflective sheet120may reflect light emitted from the plurality of light sources111to the front side or in a direction close to the front side.

In the reflective sheet120, a plurality of through holes120ais formed at positions corresponding to each of the plurality of light sources111of the light source module110. In addition, the light source111of the light source module110may pass through the through hole120aand protrude to the front of the reflective sheet120.

Further, a plurality of supporter holes120bmay be formed in the reflective sheet120at positions corresponding to the supporter500. The supporter500may pass through the supporter hole120band protrude to support the diffuser plate and/or the optical sheet140. The supporter500may be disposed in the supporter hole120b.

For example, as shown in the upper portion ofFIG.5, in the process of assembling the reflective sheet120and the light source module110, the plurality of light sources111of the light source module110is inserted into the through holes120aformed on the reflective sheet120, and the supporter500is inserted into the supporter hole120b. Accordingly, as shown in the lower portion ofFIG.5, the substrate112of the light source module110may be disposed behind the reflective sheet120, but the plurality of light sources111of the light source module110may be disposed in front of the reflective sheet120. Accordingly, the plurality of light sources111may emit light in front of the reflective sheet120.

The plurality of light sources111may emit light in various directions in front of the reflective sheet120. The light may be emitted not only toward the diffuser plate130from the light source111, but also toward the reflective sheet120from the light source111. The reflective sheet120may reflect light, which is emitted toward the reflective sheet120, toward the diffuser plate130.

Light emitted from the light source111may pass through various objects, such as the diffuser plate130and the optical sheet140. Among incident light beams passing through the diffuser plate130and the optical sheet140, some of the incident light beams may be reflected from the surfaces of the diffuser plate130and the optical sheet140. The reflective sheet120may reflect light reflected by the diffuser plate130and the optical sheet140.

The diffuser plate130may be provided in front of the light source module110and the reflective sheet120, and may evenly distribute the light emitted from the light source111of the light source module110.

Within the diffuser plate130, the diffuser plate130may diffuse light emitted from the plurality of light sources111to remove unevenness in luminance caused by the plurality of light sources111. In other words, the diffuser plate130may uniformly emit uneven light of the plurality of light sources111to the front surface.

The optical sheet140may include various sheets for improving the luminance and luminance uniformity. For example, the optical sheet140may include a diffusion sheet141, a first prism sheet142, a second prism sheet143, and a reflective polarizing sheet144.

The diffusion sheet141may diffuse light for the luminance uniformity. The light emitted from the light source111may be diffused by the diffuser plate130and may be diffused again by the diffusion sheet141included in the optical sheet140.

The first and second prism sheets142and143may increase the luminance by condensing light diffused by the diffusion sheet141. The first and second prism sheets142and143may include a prism pattern in the shape of a triangular prism, and the prism pattern, which is provided in plurality, may be disposed adjacent to each other to form a plurality of strips.

The reflective polarizing sheet144is a type of polarizing film and may transmit some of the incident light beams and reflect others for improving the luminance. For example, the reflective polarizing sheet144may transmit polarized light in the same direction as a predetermined polarization direction of the reflective polarizing sheet144, and may reflect polarized light in a direction different from the polarization direction of the reflective polarizing sheet144. In addition, the light reflected by the reflective polarizing sheet144is recycled inside the light source device100, and thus the luminance of the display apparatus10may be improved by the light recycling.

The optical sheet140is not limited to the sheet or film shown inFIGS.4and5and may include more various sheets, such as a protective sheet, or films.

FIG.6is a perspective view of a light source included in the light source device according to an embodiment.FIG.7is an exploded-perspective view of the light source shown inFIG.6.FIG.8is a cross-sectional view of the light source and a substrate shown inFIG.6taken along a direction A-A.

Referring toFIGS.6to8, the light source module110may include the plurality of light sources111. The plurality of light sources111may protrude forward of the reflective sheet120from the rear of the reflective sheet120by passing through the through hole120a. Accordingly, the light source111and a part of the substrate112may be exposed toward the front of the reflective sheet120through the through hole120a.

The light source111may include an electrical/mechanical structure disposed in a region defined by the through hole120aof the reflective sheet120. Each of the plurality of light sources111may include a light emitting diode210and an optical dome220.

It is possible to increase the number of light sources111to improve the uniformity of the surface light emitted from the light source device100and to improve the contrast ratio by the local dimming.

The light emitting diode210may include a P-type semiconductor and an N-type semiconductor for emitting light by recombination of holes and electrons. In addition, the light emitting diode210may be provided with a pair of electrodes210afor supplying hole and electrons to the P-type semiconductor and the N-type semiconductor, respectively.

The light emitting diode210may convert electrical energy into optical energy. In other words, the light emitting diode210may emit light having a maximum intensity at a predetermined wavelength to which power is supplied. For example, the light emitting diode210may emit blue light having a peak value at a wavelength indicating blue color (for example, a wavelength between 450 nm and 495 nm).

The light emitting diode210may be directly attached to the substrate112in a Chip On Board (COB) method. In other words, the light source111may include the light emitting diode210in which a light emitting diode chip or a light emitting diode die is directly attached to the substrate112without an additional packaging.

In order to reduce a region occupied by the light emitting diode210, the light emitting diode210may be manufactured as a flip chip type that does not include a Zener diode. When attaching the flip-chip type light emitting diode210, which is a semiconductor device, to the substrate112, it is possible to fuse an electrode pattern of the semiconductor device to the substrate112as it is, without using an intermediate medium such as a metal lead (wire) or ball grid array (BGA).

Because the metal lead (wire) or ball grid array is omitted as mentioned above, it is possible to reduce the size of the light source111including the flip-chip type light emitting diode210.

The light source module110, in which the flip-chip type light emitting diode210is attached to the substrate112in a chip-on-board method to reduce the size of the light source111, may be manufactured.

In the above, the flip-chip type light emitting diode210that is directly fused to the substrate112in a chip-on board manner has been described, but the light source111is not limited to the flip-chip type light emitting diode. For example, the light source111may include a package type light emitting diode.

A feeding line230and a feeding pad240for supplying power to the light emitting diode210are provided on the substrate112.

The feeding line230for supplying electrical signals and/or power to the light emitting diode210from the control assembly50and/or the power assembly60is provided on the substrate112.

As shown inFIG.8, the substrate112may be formed by alternately laminating an insulation layer251that is non-conductive and a conduction layer252that is conductive.

The insulation layer251may include a first surface251aand a second surface251b, and the conduction layer252may also include a first surface252aand a second surface252b. The conduction layer252may be laminated on a first side of the insulation layer251. For example, the conduction layer252may be laminated on the first surface251aof the insulation layer251. Further, the jumper supporter500, which will be described later, may be disposed on a first side of the conduction layer252. For example, the jumper supporter500may be disposed on the first surface252aof the conduction layer252and the jumper supporter500may be electrically connected to the conduction layer252by soldering portions601and602so as to connect a first portion401and a second portion402of the line400.

A line or pattern, through which power and/or electrical signals pass, may be formed on the conduction layer252. The conduction layer252may be formed of various materials having an electrical conductivity. For example, the conduction layer252may be formed of various metal materials, such as copper (Cu), tin (Sn), aluminum (Al), or an alloy thereof. The conduction layer252may be laminated on one surface of the insulation layer251.

A dielectric of the insulation layer251may insulate between lines or patterns of the conduction layer252. The insulation layer251may be formed of a dielectric, such as FR-4, for electrical insulation.

The feeding line230may be implemented by a line or pattern formed on the conduction layer252. The feeding line230may be electrically connected to the light emitting diode210through the feeding pad240. The feeding pad240may be formed in such a way that the feeding line230is exposed to the outside.

A protection layer253configured to prevent or suppress damages caused by an external impact and/or damages caused by a chemical action (for example, corrosion, etc.) and/or damages caused by an optical action, to the substrate112may be formed at an outermost part of the substrate112. The protection layer253may include a photo solder resist (PSR).

As shown inFIG.8, the protection layer253may cover the feeding line230to prevent the feeding line230from being exposed to the outside.

For electrical contact between the feeding line230and the light emitting diode210, a window may be formed in the protection layer253to expose a portion of the feeding line230to the outside. A portion of the feeding line230exposed to the outside through the window of the protection layer253may form the feeding pad240.

A conductive adhesive material240afor the electrical contact between the feeding line230exposed to the outside and the electrode210aof the light emitting diode210may be applied to the feeding pad240. The conductive adhesive material240amay be applied within the window of the protection layer253.

The electrode210aof the light emitting diode210may be in contact with the conductive adhesive material240a, and the light emitting diode210may be electrically connected to the feeding line230through the conductive adhesive material240a.

The conductive adhesive material240amay include a solder having an electrical conductivity. However, embodiments of the disclosure are not limited thereto, and the conductive adhesive material240amay include electrically conductive epoxy adhesives.

Power may be supplied to the light emitting diode210through the feeding line230and the feeding pad240, and in response to the supply of the power, the light emitting diode210may emit light. A pair of feeding pads240corresponding to each of the pair of electrodes210aprovided in the flip-chip type light emitting diode210may be provided.

The optical dome220may cover the light emitting diode210. The optical dome220may prevent or suppress damages to the light emitting diode210caused by an external mechanical action and/or damages to the light emitting diode210caused by a chemical action.

The optical dome220may have a dome shape formed in such a way that a sphere is cut into a surface not including the center thereof, or may have a hemispherical shape in such a way that a sphere is cut into a surface including the center thereof. A vertical cross section of the optical dome220may be a bow shape or a semicircle shape.

The optical dome220may be formed of silicone or epoxy resin. For example, the molten silicon or epoxy resin may be discharged onto the light emitting diode210through a nozzle, and the discharged silicon or epoxy resin may be cured, thereby forming the optical dome220.

Accordingly, the shape of the optical dome220may vary depending on the viscosity of the liquid silicone or epoxy resin. For example, when manufacturing the optical dome220using silicon having a thixotropic index of about 2.7 to 3.3 (appropriately, 3.0), the optical dome220may have a dome ratio, indicating a ratio of a height of a dome to a diameter of a base of the dome (a height of the dome/a diameter of a base), of approximately 0.25 to 0.31 (appropriately 0.28). For example, the optical dome220formed of silicon having a thixotropic index of approximately 2.7 to 3.3 (appropriately, 3.0) may have a diameter of the base of approximately 2.5 mm and a height of approximately 0.7 mm.

The optical dome220may be optically transparent or translucent. Light emitted from the light emitting diode210may be emitted to the outside by passing through the optical dome220.

In this case, the dome-shaped optical dome220may refract light like a lens. For example, light emitted from the light emitting diode210may be refracted by the optical dome220and thus may be dispersed.

As mentioned above, the optical dome220may disperse light emitted from the light emitting diode210as well as protecting the light emitting diode210from external mechanical and/or chemical or electrical actions.

An antistatic member may be formed in a vicinity of the optical dome220to protect the light emitting diode210from electrostatic discharge. The antistatic member may absorb electrical shock caused by electrostatic discharge generated near the optical dome220.

Referring toFIG.8, the light source module110may include the non-conductive insulation layer251, the conductive conduction layer252laminated on the front surface251aof the insulation layer251and including the feeding line230, and the non-conductive protection layer253laminated on the front surface252aof the conduction layer252. The insulation layer251may be referred to as a first layer, the conduction layer252may be referred to as a second layer, and the protection layer253may be referred to as a third layer.

The light emitting diode210may be disposed on the protection layer253. Particularly, the light emitting diode210may be disposed on the front surface of the substrate112to cover the window formed on the protection layer253.

The pair of feeding pads240may be formed on the conduction layer252and connected to the feeding line230. The pair of feeding pads240may be electrically connected to the light emitting diode210through the window formed in the protection layer253. The pair of feeding pads240may be arranged separately from each other.

The light source module110may include a reflection auxiliary layer260.

In an embodiment, the reflection auxiliary layer260along with the protection layer253may be formed between the pair of feeding pads240, thereby reducing a defect rate due to the asymmetry in the size of the pair of feeding pads240.

The light emitting diode210may include a Distributed Bragg Reflector (DBR) layer211.

The DBR layer211is a multilayer reflector composed of two materials with different refractive indices. Due to the difference in refractive index of each material, Fresnel reflection occurs at an interface of each DBR layer211. Accordingly, the light incident on the DBR layer may be reflected at a wide range of angles, and thus a beam angle of the light emitting diode210may be set to approximately 165 degrees or more.

Light emitted from the light emitting diode210may be reflected by the DBR layer211and re-reflected by the reflection auxiliary layer260. Accordingly, it is possible to prevent loss of light traveling into a space between the pair of feeding pads240.

Particularly, because the reflection auxiliary layer260is formed of a material with a higher reflectivity than the insulation layer251, the reflection auxiliary layer260may cover the front of the insulation layer251so as to prevent a case in which light traveling to the rear of the light emitting diode210is absorbed by the insulation layer251and the loss of the light occurs.

FIG.9is a view illustrating a plurality of light sources divided into a plurality of dimming blocks in the display apparatus according to an embodiment.FIG.10is a control block diagram of the display apparatus according to an embodiment.

In order to improve the power consumption while increasing the contrast ratio, the display apparatus10may perform local dimming to vary the brightness of light for each region of the light source device100in conjunction with the output image.

For example, the display apparatus10may reduce the brightness of the light of the light source111of the light source device100corresponding to a dark part of the image, so as to make the dark part of the image darker, and the display apparatus10may increase the brightness of the light of the light source111of the light source device100corresponding to a bright part of the image, so as to make the bright part of the image brighter. Accordingly, the contrast ratio of the image may be improved.

The display apparatus10may divide the light source device100into a plurality of blocks and independently adjusts the current for each block according to the input image. Image transmission from the display apparatus10may be performed through local dimming driving for each frame, and the driving of the current may be adjusted according to the number of blocks of the light source111divided within the light source device100.

As a result, the display apparatus10may 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.

For the local dimming, the plurality of light sources111included in the light source device100may be divided into a plurality of dimming blocks200. For example, as shown inFIG.9, the plurality of dimming blocks200may be composed of 5 rows and 12 columns, and thus a total of 60 dimming blocks may be provided. However, the number of dimming blocks200is not limited thereto.

Referring toFIG.9, each of the plurality of dimming blocks200may include at least one light source111. The light source device100may supply the same driving current to the light sources111belonging to the same dimming block200, and the light sources111belonging to the same dimming block200may emit light of the same brightness.

In addition, the light source device100may supply different driving current to the light sources111belonging to different dimming blocks200according to dimming data, and thus the light sources111belonging to different dimming blocks200may emit light of different brightness.

The plurality of dimming blocks200may include N*M light sources arranged in an N*M matrix (N, M are natural numbers). An N*M matrix means a matrix with N rows and M columns.

Because each light source111includes a light emitting diode, each of the plurality of dimming blocks200may include N*M light emitting diodes.

The plurality of dimming blocks200may be disposed on the substrate112. That is, N*M light emitting diodes may be disposed on the substrate112.

Image data may include information about the intensity of light transmitted by each of the plurality of pixels (or a plurality of sub-pixels) included in the display panel20. The image data may be provided to the display panel20through the panel driver30.

The panel driver30may receive image data from the image processor90. The panel driver30may drive the display panel20according to the image data. In other words, the panel driver30may convert image data, which is a digital signal (hereinafter referred to as ‘digital image data’), into an analog image signal, which is an analog voltage signal. The panel driver30may provide the analog image signal to the display panel20. The optical properties (e.g., light transmittance) of the plurality of pixels included in the display panel20may change according to the analog image 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.

The scan driver may receive a scan control signal from the timing controller. The scan driver may activate the input of any one row among the plurality of rows in the display panel20according to the scan control signal. In other words, the scan driver may convert pixels, which is included in one row among a plurality of pixels arranged in a plurality of rows and a plurality of columns, into a state capable of receiving an analog image signal. At this time, pixels other than pixels in which the input is activated by the scan driver may not receive the analog image signal.

The data driver may receive image data and data control signals from the timing controller. The data driver may output image data to the display panel20according to the data control signal. For example, the data driver may receive digital image data from the timing controller. The data driver may convert digital image data into analog image signals. Further, the data driver may provide an analog image signal to pixels included in any one input-activated row by the scan driver. At this time, pixels in which the input is activated by the scan driver may receive analog image signals. The optical properties (e.g., light transmittance) of input-activated pixels change according to the received analog image signal.

The panel driver30may drive the display panel20according to image data. Accordingly, an image corresponding to the image data may be displayed on the display panel20.

Further, the dimming data may include information about the intensity of light emitted by each of the plurality of light sources (or plurality of dimming blocks) included in the light source device100. The dimming data may be provided to the light source device100through the dimming driver170.

The light source device100may include the plurality of light sources111configured to emit light. The plurality of light sources111is arranged in a matrix form. In other words, the plurality of light sources111may be arranged in a plurality of rows and columns.

The light source device100may be divided into the plurality of dimming blocks200. Further, each of the plurality of dimming blocks200may include at least one light source.

The light source device100may output surface light by diffusing light emitted from the plurality of light sources111. The display panel20may include the plurality of pixels, and the display panel20may 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.

The light source device100may turn off the plurality of light sources corresponding to the dark part of the image, so as to make the dark part of the image darker. Accordingly, as the dark part of the image becomes darker, the contrast ratio of the image may be improved.

Hereinafter an operation, in which the light source device100controls the plurality of light sources to emit light in an area corresponding to the bright part of the image and controls the plurality of light sources to not emit light in an area corresponding to the dark part of the image, will be referred to as “local dimming.”

For the local dimming, the plurality of light sources111included in the light source device100may be divided into the plurality of dimming blocks200as shown inFIG.9. InFIG.9, a total of 60 dimming blocks in 5 rows and 12 columns are shown, but the number and arrangement of dimming blocks are not limited to those shown inFIG.9.

Each of the plurality of dimming blocks200may include at least one light source111. The light source device100may supply the same driving current to 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, light sources belonging to the same dimming block may be connected to each other in series, and thus the same driving current may be supplied to the light sources belonging to the same dimming block.

Further, the light source device100may further include a plurality of driving elements300configured to control driving current supplied to light sources included in each of the plurality of dimming blocks200. The driving elements300may each be provided to correspond to at least one dimming block200. In other words, the driving elements300may each drive the dimming block200.

Because the light sources included in the dimming block are connected to each other in series, the light sources included in the dimming block may operate as one unit and may form a light source block as one unit.

Therefore, hereinafter, “supplying driving current to the dimming block” may be interpreted as having the same meaning as “supplying driving current to the light sources included in the dimming block.”

FIG.9illustrates dimming blocks each including nine light sources, but the number and arrangement of light sources included in each dimming block are not limited to those shown inFIG.9.

As mentioned above, the image processor90may provide dimming data for the local dimming to the light source device100. The dimming data may include information about the luminance of each of the plurality of dimming blocks200. For example, the dimming data may include information about the intensity of light output from light sources included in each of the plurality of dimming blocks200.

The image processor90may obtain dimming data from image data.

The image processor90may convert image data into dimming data in various ways. For example, the image processor90may divide the image I based on 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 blocks200, and each of the plurality of image blocks may correspond to the plurality of dimming blocks200.

The image processor90may obtain a luminance value of the plurality of dimming blocks200from the image data of the plurality of image blocks. Further, the image processor90may generate dimming data by combining the luminance values of the plurality of dimming blocks200.

For example, the image processor90may obtain a luminance value of each of the plurality of dimming blocks200based on a maximum value among luminance values of pixels included in each image block.

A single image block may include a plurality of pixels, and image data of the single image block may include image data of a plurality of pixels (e.g., red data, green data, blue data, etc.). The image processor90may calculate the luminance value of each pixel based on the image data of each pixel.

The image processor90may set a maximum value among the luminance values of each pixel included in the image block as a luminance value of the dimming block corresponding to the image block. For example, the image processor90may set a maximum value among luminance values of pixels included in a ithimage block as a luminance value of a ithdimming block, and set a maximum value among luminance values of pixels included in a jthimage block as a luminance value of a jthdimming block.

The image processor90may generate dimming data by combining the luminance values of the plurality of dimming blocks200.

The dimming driver170may receive dimming data from the image processor90. The dimming driver170may drive the light source device100according to the dimming data.

The plurality of dimming blocks200may be divided into a plurality of groups. Driving current may be supplied simultaneously to dimming blocks belonging to the same group, and driving current may be supplied sequentially at different times to dimming blocks belonging to different groups. The dimming driver170may activate dimming blocks belonging to one of the plurality of groups and provide an analog dimming signal to the activated dimming blocks. Thereafter, the dimming driver170may activate dimming blocks belonging to different groups and provide an analog dimming signal to the activated dimming blocks.

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 driver170may activate dimming blocks belonging to one group and provide an analog dimming signal to the activated dimming blocks. Thereafter, the dimming driver170may activate the input of dimming blocks belonging to another row and provide an analog dimming signal to the dimming blocks in which the input is activated.

A drive circuit of each of the dimming blocks200may provide analog driving current corresponding to an analog dimming signal to the light source module110. The light sources111included in the light source module110may emit light by the analog driving current. According to dimming data, light sources belonging to the same dimming block may emit light of the same intensity. Further, according to dimming data, light sources belonging to different dimming blocks may emit light of different intensities.

The scan line S may include a first scan line S1flowing from the dimming driver170to the first driving element310, and a second scan line flowing from the dimming driver170to the second driving element320. The first scan line S1and the second scan line S2may be provided in plurality.

The out line O may transmit a data signal from the driving element300to the light source111. The number of out lines O may vary according to the scan signal and data signal flowing from the dimming driver170to the driving element300.

The out line O may include a first out line O1flowing from the first driving element310to the first light source111, and a second out line O2flowing from the second driving element320to the second light source111.

The number of data lines D1and D2, scan lines S, and out lines O is not limited to the above examples.

The line400may be disposed on one side of the substrate112. For example, the line400may not be formed on both surfaces forming the outside of the substrate112, but may be formed only on one side forming the outside of the substrate112. For example, the line400may be provided on the first side of the substrate112. The first side may be a side of the substrate112facing the display panel.

Because the line400is formed only on the first side of the substrate112, the lines400may intersect each other (region B inFIG.12). An intersection area between the lines400may be formed in plurality. For example, the data lines D1and D2for transferring a data signal from the dimming driver170to the driving element300may intersect the scan line S for transferring a scan signal from the dimming driver170to the driving element300. The data lines D1and D2may intersect the power line V configured to supply power (driving voltage: VLED) to the light source111and the driving element300. The scan line S may intersect the power line V. Further, the out line O may intersect one of the power line V, the scan line S, and the data lines D1and D2.

For example, the first data line D1, the first scan line S1, and the power line V flowing to the first driving element310may intersect the first out line O1flowing from the first driving element310to the first light source111. Further, the second data line D2, the second scan line S, and the power line V flowing to the second driving element320may intersect the second out line O2flowing from the second driving element320to the second light source111. In addition, the line400connected to the first driving element310may intersect the line400connected to the second driving element320.

When the lines400intersect, one of the lines400may be disconnected. Therefore, it is required to prevent the lines400from being disconnected so as to allow all lines to be electrically connected. Further, the line400may pass through the ground (GND) on one side of the substrate112, and even in this case, it is required to prevent the disconnection of the line400.

According to an embodiment, the display apparatus may include the jumper supporter500. For example, the light source device100may include the jumper supporter500. The jumper support500may be provided in plurality.

By using the jumper supporter500, the display apparatus may prevent the disconnection of the line400while supporting the optical members130and140. Because the jumper supporter500allows the line400provided on one side of the substrate112to intersect while supporting the optical members130and140, it is possible to reduce the number of jumper connectors that is required for the intersection area between the lines400. Therefore, by reducing the number of jumper connectors, it is possible to reduce costs and improve process efficiency.

The line400may include a first line, a second line, a third line, and a fourth line. In this case, the first line may be the data line D1and D2, the second line may be the scan line S, the third line may be the power line V, and the fourth line may be the out line O. However, embodiments of the disclosure are not limited to the above example, and the first line may be referred to as a scan line S, a power line V, or an out line O, or may be referred to as another line. Further, the second line may be referred to as a data line D1or D2, a power line V, or an out line O, or may be referred to as another line. Further, the third line may be referred to as a data line D1or D2, a scan line S, or an out line O, or may be referred to as another line. Further, the fourth line may be referred to as a data line D1or D2, a scan line S, or a power line V, or may be referred to as another line.

Various substrate components such as capacitors, resistors, and connectors as well as the line400, the light source111, and the driving element300may be disposed on the substrate112. The line400may include all lines400for electrically connecting the light source111, the driving element300, the capacitor, the resistor, the connector, etc.

As for the substrate112of the display apparatus according to an embodiment, the various components described above may be disposed only on the first side facing the display panel20among the outer surfaces251band252a, and thus it is possible to use the jumper supporter500to prevent the disconnection of the lines400configured to electrically connect the various components. Accordingly, there is no need to perform the process on both outer surfaces251band252aof the substrate112, and thus the process efficiency may be increased.

FIG.13is a view illustrating a jumper supporter being electrically connected to the substrate in the display apparatus according to an embodiment.FIG.14is a cross-sectional view of the jumper supporter and the substrate shown inFIG.13taken along a direction C-C″. The reflective sheet120is omitted inFIG.13.

Referring toFIGS.13and14, the display apparatus according to an embodiment includes the substrate112and the line400provided on the substrate112.

The substrate112may include the insulation layer251and the conduction layer252.

The substrate112may include a first side facing the display panel20and a second side opposite to the first side. The substrate112may include the plurality of outer surfaces provided on the outermost side. The outer surface of the substrate112may include the first surface252aand the second surface251b. The first surface252aand the second surface251bmay be disposed on opposite sides. The first surface252amay be the front surface of the substrate112, and the second side251bmay be the rear surface of the substrate112. The first surface252amay be the front surface of the conduction layer252, and the second surface251bmay be the rear surface of the insulation layer251. The first surface252amay be a side facing the display panel20.

The line400may be part of conduction layer252. The line400may be formed only on the first side of substrate112. That is, in order to form the line400, it is sufficient that the conduction layer252is formed on only one surface without being formed on both outer surfaces of the substrate112. For example, the line400may be formed on the first surface252a.

Because the lines400are wired only to the first side of the substrate112, the lines400may intersect each other. When the lines400intersect each other, a single line400may be disconnected. The supporter500may be used to electrically connect the disconnected line400.

The display apparatus according to an embodiment may include the supporter500. The supporter500may be disposed on the substrate112to support the optical members130and140. For example, the supporter500may be disposed on the first side of the substrate112facing the display panel20and the optical members130and140.

The supporter500may be electrically connected to the substrate112. The supporter500may allow circuit patterns, which intersect each other, to be connected without being disconnected. For example, the supporter500may be disposed in an area where one line400and other lines400intersect on the first side of the substrate112, so as to electrically connect the one line400and to guide the other lines400to be spaced apart from the one line400. The supporter500may be referred to as the jumper supporter500.

Because the jumper supporter500allows the lines400provided on one side of the substrate112to intersect each other while supporting the optical members130and140, it is possible to reduce the number of jumper connectors required on an intersection area between the lines400. Therefore, by reducing the number of jumper connectors, it is possible to reduce costs and improve process efficiency.

As illustrated inFIG.13, when the data line D intersects the scan line S, the power line V, the out line O, and the timing line420, the jumper supporter500may allow each line to be connected without the disconnection.

However, the case in which the jumper supporter500connects the lines400is not limited to the above example. For example, when the scan line S intersects the data line D, the power line V, the out line O, and the timing line420, the jumper supporter500may allow each line to be connected without the disconnection. Alternatively, when the power line V intersects the scan line S, the data line D, the out line O, and the timing line420, the jumper supporter500may allow each line to be connected without the disconnection. Alternatively, when the out line O intersects the scan line S, the data line D, the power line V, and the timing line420, the jumper supporter500may allow each line to be connected without the disconnection. Alternatively, when the timing line420intersects the scan line S, the data line D, the out line O, and the power line V, the jumper supporter500may allow each line to be connected without the disconnection.

Further, even when the scan line S and the power line V extend in a parallel direction, and the out line O and the data line D extend in a direction intersecting the scan line S and the power line V, the jumper supporter500may allow each line to be connected without the disconnection.

Further, even when only one line400intersects, the jumper supporter500may allow each line to be connected without the disconnection.

The line400may include the first portion401and the second portion402, respectively. For example, each of the data line D, the scan line S, the power line V, and the out line line O may be divided into the first portion401and the second portion402. The first portion401and the second portion402may be spaced apart from each other on the conduction layer252of the substrate112. The jumper supporter500may electrically connect the first portion401and the second portion402. For example, when the data line D is divided into a first portion401and a second portion402, the jumper supporter500may electrically connect the first portion401and the second portion402and allow one of the scan line S, the power line V, and the out line O to be spaced apart from the data line D.

In the display apparatus according to an embodiment, the jumper supporter500may include a base510mounted on one surface of the substrate112. For example, the base510may be disposed on the insulation layer251and the conduction layer252. Although the base510is shown to have a substantially rectangular shape, the shape of the base510is not limited to thereto.

The jumper supporter500may further include a support portion520. The support portion520may protrude from the base510to support the optical members130and140. The support portion520may be formed to have a smaller cross-sectional area in a direction away from the base510. For example, the support portion520may have a cone shape. However, the shape of the support portion520is not limited to thereto.

The base510and the support portion520may be formed integrally. When the base510and the support portion520are formed as one piece, the one piece may be referred to as a body.

The jumper supporter500may include a connection portion530connected to the conduction layer252. The connection portion530may be connected to the circuit pattern and/or line400provided on the conduction layer252. For example, the connection portion530may be electrically connected to the lines400connected to the driving element300and/or the light source111.

The connection portion530may be formed adjacent to the conduction layer252to be soldered to the conduction layer252. For example, the connection portion530may be formed on the base510.

At least one connection portion530may be provided. The connection portion530may correspond to the number of lines400that intersect in the area where the jumper supporter500is disposed. For example, when the data line D intersects the scan line S, the power line V, the out line O, and the timing line420, the jumper supporter500may be connected to the data line D or connected to the scan line S, the power line V, the out line O, and the timing line420so as to allow each line to be connected without the disconnection. As shown inFIG.13, when the connection portion530is connected to the scan line S, the power line V, the out line O, and the timing line420, four connection portions530may be provided.

The connection portion530may be soldered so as to be electrically connected to the conduction layer252. For example, a first end of the connection portion530is connected to the first portion401of the disconnected line400through a first soldering portion601, and a second end of the connection portion530may be connected to the second portion402of the disconnected line400through a second soldering portion602.

The first soldering portion601may be provided on the first end side of the connection portion530, and the second soldering portion602may be provided on the second end side of the connection portion530. The first soldering portion601may electrically connect the first portion401and the connection portion530, and the second soldering portion602may electrically connect the second portion402and the connection portion530, thereby electrically connecting the first portion401and the second portion402which are disconnected.

When the jumper supporter500electrically connects the first portion401and the second portion402of the line400, the jumper supporter500may be spaced apart from the substrate112. For example, as the jumper supporter500and the insulation layer251are spaced apart from each other, a space700may be formed between the jumper supporter500and the insulation layer251. The space700may be an area where the first portion401and the second portion402of the line400are disconnected.

When the lines400intersect each other (refer toFIGS.12and13), one of the lines400may be electrically connected by the jumper supporter500, and another one403of the lines400may be disposed in the space700formed between the supporter500and the insulation layer251. Therefore, the one line and the another line403of the lines400may be wired without interfering with each other.

The jumper supporter500may be used in the relationship between the line400and the ground GND, as well as between the lines400. For example, when the line400is wired to the substrate112, the line400may not bypass the ground GND. At this time, the line400may bypass the ground GND through the jumper supporter500.

In an embodiment, components including the line400and the ground GND may be formed only on the one surface252aof the outer surfaces252aand251bof the substrate112. Accordingly, there is no need to wire both outer surfaces252aand251bof the substrate112, and the circuit only needs to be wired to the one surface252aof the substrate112, thereby improving process efficiency.

The scan line S may be wired to the jumper supporter500. For example, the first portion401and the second portion402of the scan line S may be connected through the connection portion530.

The data line D may be spaced apart from the scan line S. The data line D may pass through the space700between the jumper supporter500and the insulation layer251. For example, because the jumper supporter500is disposed on the conduction layer252, the space700may be formed between the jumper supporter500and the insulation layer251, and the data line D may be wired to the space700.
