Detailed Description

The embodiments described in the present disclosure and the configurations shown in the drawings are merely examples of the embodiments of the present disclosure, and may be modified in various ways to replace the embodiments and drawings of the present disclosure when submitting the present application.

Furthermore, the same reference numerals or symbols shown in the drawings of the present disclosure denote elements or components performing substantially the same functions.

Furthermore, the terminology used herein is used to describe embodiments and is not intended to limit and/or restrict the present disclosure. The singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. In this disclosure, the terms "comprises," "comprising," "includes," and the like are used to specify the presence of stated features, integers, steps, operations, elements, components, or groups thereof, but do not preclude the presence or addition of one or more other features, elements, steps, operations, elements, components, or groups thereof.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, the elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element could be termed a second element, and a second element could be termed a first element, without departing from the scope of the present disclosure. The term "and/or" includes a plurality of combinations of related items or any of a plurality of related items.

Terms such as "unit," "module," "member" and "block" can be implemented in hardware or software. According to embodiments, a plurality of "units", "modules", "means" and "blocks" may be implemented as a single component, or a single "unit", "module", "means" and "block" may include a plurality of components.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly or indirectly connected to the other element, with indirect connection including "connection via a wireless communication network.

Furthermore, when a portion "comprises" or "comprising" an element, unless specifically stated to the contrary, the portion may further comprise other elements without excluding other elements.

Throughout the description, when one element is "on" another element, this includes not only the case where the element is in contact with the other element, but also the case where another element exists between the two elements.

Orientation guidelines (i.e. "compasses") are provided in the various figures. The guide is intended to provide a consistent sense of orientation between the figures so that the orientation of the elements shown in the different figures relative to one another can be more easily determined. It should be noted that the terms used for orientation are selected for convenience and do not limit the orientation of the illustrated elements relative to elements that are not part of the illustrated system. As just one example, the indication of the "up" direction in the figures does not require that the display shown in the figures be installed so that the indicated side of the display is oriented upward relative to the ground; if the display is mounted in a longitudinal direction, rather than in the lateral direction as shown in the figures, the "up" direction indicated in the figures may be horizontal with respect to the ground. It is further noted that, for example, the use of "above" to describe certain elements herein does not necessarily mean that the "up" direction shown in the guideline corresponds to, and similar modifiers will also be apparent.

Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

Fig. 1 is a diagram illustrating an external appearance of a display device according to an embodiment of the present disclosure.

The display apparatus 10 is a device that processes an image signal received from the outside and visually displays the processed image. The following exemplifies the case where the display device 10 is a television, but the present disclosure is not limited thereto. For example, the display apparatus 10 may be implemented in various forms such as a monitor, a portable multimedia device, a portable communication device, and the like, and the shape of the display apparatus 10 is not limited as long as the display apparatus can visually display an image.

As an example, the display apparatus 10 may be a large display (LFD) installed outdoors (e.g., a roof of a building or a bus stop). The "outdoors" is not limited to the outside of a building, and thus the display device 10 according to the embodiment may be installed anywhere as long as the display device can be accessed by a large number of people, even indoors, such as subway stations, shopping malls, movie theaters, companies, and shops. Further, the display device 10 is not limited to LFD or "outdoor" mounted examples, but may have any size and any mounting location.

The display apparatus 10 may receive content data including video data and audio data from various content sources and output video and audio corresponding to the video data and the audio data. For example, the display apparatus 10 may receive content data through a broadcast receiving antenna or a cable, receive content data from a content playback device, or receive content data from a content providing server of a content provider.

As shown in the embodiment shown in fig. 1, the display device 10 includes a main body 11, a screen 12 provided to display an image I, and a support 19 provided below the main body 11 to support the main body 11.

The main body 11 may form an external appearance of the display apparatus 10, and the main body 11 may include components configured to allow the display apparatus 10 to display an image I and perform various functions. Although the main body 11 shown in fig. 1 is in the form of a flat plate, the shape of the main body 11 is not limited thereto. For example, the body 11 may have a curved plate shape.

The screen 12 may be formed on the front surface of the main body 11 and display the image I. For example, the screen 12 may display a still image or a moving image. Further, the screen 12 may display a two-dimensional plane image or a three-dimensional image using binocular parallax of the user.

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 a combination of light emitted from the plurality of pixels P. For example, the image I may be formed in the screen 12 by combining light emitted from the plurality of pixels P into a mosaic (mosaic).

Each of the plurality of pixels P may emit light of different brightness and different color. In order to emit light of different brightness, each of the plurality of pixels P may include a self-luminous panel (e.g., a light emitting diode panel) configured to directly emit light, or a non-self-luminous panel (e.g., a display panel) configured to transmit or block light emitted by the light source device.

In order to emit light of various colors, the plurality of pixels P may include sub-pixels PR, PG, and PB, respectively.

The sub-pixels PR, PG, and PB may include a red sub-pixel PR emitting red light, a green sub-pixel PG emitting green light, and a blue sub-pixel PB emitting blue light. For example, red light may represent a light beam having a wavelength of about 620nm (nanometers, parts per billion meters) to 750nm, green light may represent a light beam having a wavelength of about 495nm to 570nm, and blue light may represent a light beam having a wavelength of about 450nm to 495 nm.

By combining the red light of the red subpixel PR, the green light of the green subpixel PG, and the blue light of the blue subpixel PB, each of the plurality of pixels P may emit light of different brightness and different color.

Fig. 2 is an exploded view of the display device 10 shown in fig. 1 according to an embodiment of the present disclosure.

As shown in the embodiment shown in fig. 2, various components configured to generate an image I on the screen S may be provided inside the main body 11 (refer to fig. 1).

For example, the main body 11 shown in fig. 1 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 assembly 50 configured to control operations of the light source device 100 and the display panel 20, and a power supply assembly 60 configured to supply power to the light source device 100 and the display panel 20. Further, the main body 11 may include a bezel 13, a frame middle mold 14, a bottom chassis 15, and a rear cover 16, which are provided to support and fix the display panel 20, the light source device 100, the control assembly 50, and the power supply assembly 60.

The light source device 100 may include a point light source configured to emit monochromatic light or white light. The light source device 100 may refract, reflect, and scatter light so as to convert light emitted from a point light source into uniform surface light. For example, the light source device 100 may include a plurality of light sources configured to emit monochromatic light or white light, a diffusion plate configured to diffuse light incident from the plurality of light sources, a reflection sheet configured to reflect light emitted from the plurality of light sources and a rear surface of the diffusion plate, and an optical sheet configured to refract and scatter light emitted from a front surface of the diffusion plate.

As described above, the light source device 100 may refract, reflect, and scatter light emitted from the light source, thereby emitting uniform surface light toward the front side.

Fig. 3 is a side cross-sectional view of the display panel 20 of the display device 10 shown in fig. 2 according to an embodiment of the present disclosure.

The display panel 20 may be disposed 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.

The front surface of the display panel 20 may form the screen 12 of the display device 10 described above with reference to fig. 1, and the display panel 20 may form a plurality of pixels P. The plurality of pixels P may independently block or transmit light from the light source device 100, and the light transmitted through the plurality of pixels P may form an image I displayed on the screen 12.

For example, as shown in the embodiment shown in fig. 3, the display panel 20 may include a first polarizing film 21, a first transparent substrate 22, a pixel electrode 23, a thin film transistor 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.

The first transparent substrate 22 and the second transparent substrate 28 may fixedly support the pixel electrode 23, the thin film transistor 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 transparent resin.

The first and second polarizing films 21 and 29 may be disposed outside the first and second transparent substrates 22 and 28.

Each of the first polarizing film 21 and the second polarizing film 29 may transmit a specific light beam and block other light beams. For example, the first polarizing film 21 may transmit a light beam having a magnetic field vibrating in a first direction and block other light beams. Further, the second polarizing film 29 may transmit a light beam having a magnetic field vibrating in the second direction and block other light beams. In this case, the first direction and the second direction may be perpendicular to each other. Accordingly, the polarization direction of the light transmitted through the first polarization film 21 and the polarization direction of the light transmitted through the second polarization film 29 may be perpendicular to each other. As a result, in general, light may not pass through the first polarizing film 21 and the second polarizing film 29 at the same time.

The color filter 27 may be disposed inside the second transparent substrate 28.

The color filter 27 may include a red filter 27R transmitting red light, a green filter 27G transmitting green light, and a blue filter 27B transmitting blue light. The red filter 27R, the green filter 27G, and the blue filter 27B may be disposed in parallel with each other. The region in which the color filter 27 is formed may correspond to the above-described pixel P. The region in which the red filter 27R is formed may correspond to the red sub-pixel PR, the region in which the green filter 27G is formed may correspond to the green sub-pixel PG, and the region in which the blue filter 27B is formed may correspond to the blue sub-pixel PB.

The pixel electrode 23 may be disposed inside the first transparent substrate 22, and the common electrode 26 may be disposed inside the second transparent substrate 28.

The pixel electrode 23 and the common electrode 26 may be formed of a metal material through which conduction is performed, and the pixel electrode 23 and the common electrode 26 may generate an electric field to change the arrangement of liquid crystal molecules 25a forming a liquid crystal layer 25 to be described below.

The pixel electrode 23 and the common electrode 26 may be formed of a transparent material, and may transmit light incident from the outside. For example, the pixel electrode 23 and the common electrode 26 may include Indium Tin Oxide (ITO), indium Zinc Oxide (IZO), silver nanowires (Ag nanowires), carbon Nanotubes (CNT), graphene, poly (3, 4-ethylenedioxythiophene) (PEDOT), or a combination thereof.

A Thin Film Transistor (TFT) 24 may be disposed inside the first transparent substrate 22.

The TFT 24 may transmit or block a current flowing through the pixel electrode 23. For example, an electric field may be formed or removed between the pixel electrode 23 and the common electrode 26 in response to turning on (off) or turning off (on) of the TFT 24.

The TFT 24 may be formed of polysilicon and may be formed through a semiconductor process (e.g., photolithography, deposition, ion implantation, etc.).

The 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 crystals represent an intermediate state between solid (crystalline) and liquid. Most liquid crystal materials are organic compounds and the molecular shape is that of an elongated rod, with the orientation of the molecules being in an irregular state in one direction but in a regular state in the other direction. As a result, the liquid crystal has fluidity of liquid and optical anisotropy of crystal (solid).

In addition, the liquid crystal also exhibits optical properties according to a change in an electric field. For example, in the liquid crystal, the orientation of molecules forming the liquid crystal may be changed according to a change in an electric field. In response to an electric field generated in the liquid crystal layer 25, the liquid crystal molecules 25a of the liquid crystal layer 25 may be disposed along the direction of the electric field. The liquid crystal molecules 25a may be irregularly arranged or arranged along an alignment layer (not shown) in response to no electric field being generated in the liquid crystal layer 25. As a result, the optical properties of the liquid crystal layer 25 may vary depending on the presence or absence of an electric field across the liquid crystal layer 25.

Referring back to fig. 2, a cable 20a configured to transmit image data to the display panel 20, and a display driver integrated circuit (DDI) (hereinafter referred to as a "driver IC") 30 configured to process digital image data and output analog image signals may be disposed at one side of the display panel 20.

The cable 20a may electrically connect the control assembly 50 and/or the power assembly 60 to the driver IC 30, and may also electrically connect the driver IC 30 to the display panel 20. The cable 20a may include a flexible flat cable or a thin film cable that is bendable.

The driver IC 30 may receive image data and power from the control assembly 50 and/or the power supply assembly 60 through the cable 20 a. The driver IC 30 may transmit the image data and the driving current to the display panel 20 through the cable 20 a.

Further, the cable 20a and the driver IC 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 driver IC 30 may be disposed on the cable 20 b. However, the present disclosure is not limited thereto, and the driver IC 30 may be disposed on the display panel 20.

The control assembly 50 may include a control circuit configured to control the operation of the display panel 20 and the light source device 100. The control circuit may process image data received from an external content source, transmit the image data to the display panel 20, and transmit dimming data to the light source device 100.

The power supply assembly 60 may supply power to the display panel 20 and the light source device 100 to allow the light source device 100 to output surface light and allow the display panel 20 to block or transmit light of the light source device 100.

The control assembly 50 and the power assembly 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 resistive element, a processor, and a power supply circuit board on which the capacitor, the coil, the resistive element, and the processor are mounted. 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.

Fig. 4 is an exploded view of the light source device 100 shown in fig. 2 according to an embodiment of the present disclosure. Fig. 5 is a diagram illustrating coupling between a light source module and a reflective sheet included in the light source device 100 illustrated in fig. 4 according to an embodiment of the present disclosure.

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

The light source module 110 may be disposed at the rear of the display panel 20. The light source module 110 may include a plurality of light sources 111 configured to emit light, and a Printed Circuit Board (PCB) 112 configured to support and/or fix the plurality of light sources 111. PCB 112 may define an upper surface thereof and a lower surface opposite the upper surface. A plurality of light sources 111 may be mounted on an upper surface of the PCB 112. A plurality of components (not shown) may also be mounted on the upper surface of the PCB 112.

The plurality of light sources 111 may be arranged in a predetermined pattern to allow light to be emitted at a uniform brightness. The plurality of light sources 111 may be disposed in the same manner as a distance between one light source and a light source adjacent thereto.

For example, as shown in the embodiment shown in fig. 4, a plurality of light sources 111 may be arranged in rows and columns. Thus, a plurality of light sources may be arranged such that an approximate square is formed by four adjacent light sources. Further, any one of the light sources may be disposed adjacent to the four light sources, and the distances between one light source and the four adjacent light sources may be substantially the same.

Alternatively, in an undepicted embodiment, the plurality of light sources may be arranged in a plurality of rows, and the light sources belonging to each row may be arranged at the center of two light sources belonging to adjacent rows. Thus, the plurality of light sources may be arranged such that an approximately equilateral triangle is formed by three adjacent light sources. In this case, one light source may be disposed adjacent to six light sources, and the distances between one light source and six adjacent light sources may be substantially the same.

However, the pattern in which the plurality of light sources 111 are disposed is not limited to the above-described pattern, and the plurality of light sources 111 may be arranged in various other patterns to allow light to be emitted at uniform brightness.

Each light source 111 may employ an element configured to emit monochromatic light (light of a specific wavelength; e.g., blue light) or white light (e.g., mixed light of red light, green light, and blue light) in various directions by receiving power. For example, each light source 111 may include a Light Emitting Diode (LED).

The PCB 112 may fix the plurality of light sources 111 to prevent a position change of the light sources 111. Further, the PCB 112 may provide power for the light source 111 to emit light to the light source 111.

The PCB 112 may be provided with synthetic resin or tempered glass or a Printed Circuit Board (PCB) on which the plurality of light sources 111 are fixed and on which conductive power lines for supplying power to the light sources 111 are formed.

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

In the reflection 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. In this way, the light source 111 of the light source module 110 may pass through the through hole 120a and protrude to the front of the reflection sheet 120.

For example, as shown in the upper part of fig. 5, in assembling the reflective sheet 120 and the light source module 110, the plurality of light sources 111 in the light source module 110 may be inserted into the through holes 120a formed on the reflective sheet 120. Accordingly, as shown in the lower part of fig. 5, the PCB 112 of the light source module 110 may be disposed at the rear of the reflection sheet 120, but the plurality of light sources 111 in the light source module 110 may be disposed at the front of the reflection sheet 120.

Accordingly, the plurality of light sources 111 may emit light in front of the reflection sheet 120.

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

Light emitted from the light source 111 may pass through various objects, such as the diffusion plate 130 and the optical sheet 140. Of the incident light beams passing through the diffusion plate 130 and the optical sheet 140, some of the incident light beams may be reflected from the surfaces of the diffusion plate 130 and the optical sheet 140. The reflection sheet 120 may reflect light reflected by the diffusion plate 130 and the optical sheet 140.

The diffusion plate 130 may be disposed in front of the light source module 110 and the reflection sheet 120, and may uniformly distribute light emitted from the light source 111 of the light source module 110. As described above, the plurality of light sources 111 may be disposed at various positions on the rear surface of the light source device 100. However, even when the plurality of light sources 111 are disposed on the rear surface of the light source device 100 at equal intervals, unevenness in brightness may occur according to the positions of the plurality of light sources 111. Within the diffusion plate 130, the diffusion plate 130 may diffuse light emitted from the plurality of light sources 111 to remove brightness non-uniformity caused by the plurality of light sources 111. In other words, the diffusion plate 130 may uniformly emit the non-uniform light of the plurality of light sources 111 to the front surface.

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 polarizer 144.

The diffusion sheet 141 may diffuse light for brightness uniformity. The light emitted from the light source 111 may be diffused by the diffusion plate 130, and may be diffused again by the diffusion sheet 141 included in the optical sheet 140.

The first and second prism sheets 142 and 143 may increase brightness by condensing light diffused by the diffusion sheet 141. The first and second prism sheets 142 and 143 may include prism patterns of triangular prism shape, and the prism patterns provided in plurality may be disposed adjacent to each other to form a plurality of bars.

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

The optical sheet 140 is not limited to the sheet or film shown in fig. 4, and may include various sheets in addition or instead, such as a protective sheet or film, and the like.

Fig. 10 is a sectional view at the division shown in fig. 7, schematically illustrating a state in which a connector according to an embodiment of the present disclosure is mounted on an upper surface of a printed circuit board.

As shown in the embodiment shown in fig. 6-10, the connector 200 may be mounted on the PCB 112. The connector 200 may be mounted on an upper surface of the PCB 112. A through hole 113 may be formed in the PCB112 to allow the connector 200 to be mounted on an upper surface of the PCB 112. The connector 200 may be mounted on the upper surface of the PCB112 by being inserted into the through hole 113 on the upper surface of the PCB 112.

The connector 200 may include a connector body 210 inserted in a through hole 113 formed in the PCB 112. A portion of the connector body 210 may protrude to the lower surface of the PCB 112 through the through hole 113. That is, the lower portion of the connector body 210 may protrude to the lower surface of the PCB 112 through the through hole 113 and pass through the lower surface of the PCB 112. The connector body 210 may include a connection member 211, and the connection member 211 protrudes through the lower surface of the PCB 112 through the through hole 113. The connector body 210 may define a first side surface 210a and a second side surface 210b opposite to the first side surface 210a, and is parallel to an upper surface of the PCB 112 when inserted, wherein each of the first and second side surfaces faces an inner edge of the through hole 113. As shown, when the connector body 210 is inserted into the through hole 113, the first side surface 210a faces in the direction indicated as "up", and the second side surface 210b faces in the direction indicated as "down". However, this is not a requirement, and the first side surface 210a and the second side surface 210b may each face in any pair of opposite directions parallel to the upper surface of the PCB 112.

Behind the PCB 112, referring back to fig. 2, the chassis 15 and the rear cover 16 may be provided so that the PCB 112 and other elements of the light source device 100 may be assembled thereto. A power supply assembly 60 configured to supply power to the plurality of light sources 111 may be provided on the rear cover 16. A control assembly 50 configured to control the operation of the plurality of light sources 111 may be provided on the rear cover 16. The connection member 211 may be electrically connected to the control assembly 50 and the power assembly 60 through a wire W. Although not shown in the drawings, the connection member 211 may be connected to other circuits than the control assembly 50 and the power supply assembly 60 through a wire W. Furthermore, separate fittings may be added for connection between the connection member 211 and other circuits. Although the drawings illustrate that the connection member 211 is electrically connected to the control assembly 50 and the power assembly 60 through the wire W, the present disclosure is not limited thereto. That is, the connection member 211 may be electrically connected to the control assembly 50 and the power assembly 60 through a Flexible Flat Cable (FFC).

The connector 200 may include a plurality of connector terminals 220, with the connector terminals 220 mounted on or otherwise disposed adjacent to the upper surface of the PCB 112 upon insertion. The plurality of connector terminals 220 may electrically connect the connector body 210 with the first and second members 112a, 112b of the PCB 112, which are defined as portions of the PCB 112 adjacent to the first and second side surfaces 210a, 210b of the connector body 210, respectively, when the connector body 210 is inserted into the through-hole 113. Portions of the upper surface of the PCB 112 on the first and second members 112a and 112b may be defined as first and second surface portions of the PCB 112, respectively. That is, when the connector body 210 is inserted into the through hole 113, the first surface portion is defined as a portion of the upper surface of the printed circuit board adjacent to the first side surface of the connector body, and the second surface portion is defined as a portion of the upper surface of the printed circuit board adjacent to the second side surface. As shown, when the connector body 210 is inserted into the through hole 113, the first member 112a is a portion of the PCB 112 adjacent to the connector body 210 in an "up" direction indicated with respect to the connector body 210, and the second member 112b is a portion of the PCB 112 adjacent to the connector body 210 in a "down" direction indicated with respect to the connector body 210. However, this is not a requirement, and the first and second members 112a and 112b may be any portion of the PCB 112 adjacent to the first and second side surfaces 210a and 210b, respectively.

In the example embodiment shown in fig. 8, the plurality of connector terminals 220 may be electrically connected to a plurality of PCB terminals 114 extending from metal wires (not shown) disposed on the PCB 112. Each PCB terminal 114 may be disposed on one of the first member 112a and the second member 112b and proximate one of the first side surface 210a and the second side surface 210b of the connector body 210.

The plurality of PCB terminals 114 may include a first PCB terminal 114a and a third PCB terminal 114c, each disposed on the first member 112 a. The plurality of PCB terminals 114 may also include a second PCB terminal 114b and a fourth PCB terminal 114d, each disposed on the second member 112 b.

As shown in fig. 8, the plurality of connector terminals 220 may include first connector terminals 220a electrically connecting the first member 112a of the PCB 112 to the connector body 210. More specifically, the first connector terminal 220a may electrically connect the connector body 210 to the first PCB terminal 114a disposed on the first member 112a of the PCB 112.

As shown in fig. 8, the plurality of connector terminals 220 may include second connector terminals 220b electrically connecting the second member 112b of the PCB 112 to the connector body 210. More specifically, the second connector terminal 220b may electrically connect the connector body 210 to the second PCB terminal 114b disposed on the second member 112b of the PCB 112.

As shown in fig. 8, the plurality of connector terminals 220 may include a third connector terminal 220c that electrically connects the first member 112a of the PCB 112 to the second member 112b of the PCB 112. More specifically, the third connector terminal 220c may electrically connect the third PCB terminal 114c disposed on the first member 112a of the PCB 112 to the fourth PCB terminal 114d disposed on the second member 112b of the PCB 112.

An additional challenge in the related art is the length and complex arrangement of vias formed on the PCB to electrically connect all components. However, as described above, the plurality of connector terminals 220 may electrically connect the first member 112a of the PCB 112 adjacent to the first side surface 210a of the connector body 210 to the second member 112b of the PCB 112 adjacent to the second side surface 210b of the connector body 210. Accordingly, the circuit connection configuration may be simplified and the vias formed on the PCB 112 for electrical connection may be removed or reduced.

It should be noted that since the width of the through hole 113 into which the connector body 210 is inserted is relatively small, it may be difficult to arrange the connection member 211 on the lower portion of the connector body 210, for example, as shown in the embodiment shown in fig. 9 and 10.

Fig. 11 is a sectional view schematically illustrating a state in which an auxiliary connector connected to a wire is assembled to a connector body 210 of a connector 200 according to an embodiment of the present disclosure.

Since the width of the through hole 113 into which the connector body 210 is inserted is relatively small, it may be difficult to arrange the connection member 211 as shown in fig. 9 and 10 at a desired position for the wire W. However, as shown in the embodiment shown in fig. 11, the auxiliary connector 230 electrically connected to the control assembly 50 and the power assembly 60 through the wire W may be assembled, attached or otherwise connected to the lower portion of the connector body 210. As an assembly step of the display device, the auxiliary connector 230 may be detachably connected to the lower portion of the connector body 210, or may be permanently coupled. The lower portion of the connector body 210 may be configured to be removably or permanently coupled to the auxiliary connector 230 during manufacture. By this coupling, the lower portion of the connector body 210 may be electrically connected to the auxiliary connector 230, and electrically connected to the control assembly 50 and the power supply assembly 60 through the auxiliary connector 230 and the wire W. In this way, when the through hole 113 has a relatively small width, the auxiliary connector 230 configured to function as a connection member may be additionally coupled to the lower portion of the connector body 210. Such an arrangement avoids the difficulties of arranging the connection member 211 described above.

While the embodiments of the connector and printed circuit board disclosed herein have been described in the context of a display device, it should be noted that the embodiments of the connector and printed circuit board may be applied to and used in other systems that use printed circuit boards. Such systems cover a wide range of electronic devices and include, but are not limited to, telecommunications devices, recording devices, computing devices, and control systems for other hardware.

Although the connectors, display devices including the connectors, and other components have been shown and described in particular shapes, locations and orientations in the drawings, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
