Abstract
Description
Technical Field
[0001] This disclosure relates to a display device, and more particularly to, for example, but not limited to, a display device having a structure with improved durability. Background Technology
[0002] The content described in this section is only to provide background information about this disclosure and does not constitute related technology.
[0003] As society enters the mature information age, the field of display devices that visually represent electrical information signals has developed rapidly, and research is underway to improve performance aspects such as reduced thickness, lighter weight, and lower power consumption for various types of display devices.
[0004] Such display devices may include liquid crystal display (LCD) devices, quantum dot display (QD) devices, field emission display (FED) devices, electrowetting display (EWD) devices, and organic light-emitting diode (OLED) display devices.
[0005] Display devices have been miniaturized to enhance portability for users or to be installed in mobile devices such as vehicles, thereby improving user convenience.
[0006] In addition, display devices have been continuously improved to increase screen resolution and brightness, thereby providing users with clearer images.
[0007] The descriptions provided in the background section should not be assumed to be prior art simply because they are mentioned in or associated with that section. The background section may include information describing one or more aspects of the subject matter art, and the descriptions in that section do not limit this disclosure. Summary of the Invention
[0008] The display device may include a circuit board for operating the display device. The circuit board may be provided with a power supply for supplying power to the display device and a control unit for controlling the operation of the display device.
[0009] Circuit boards may include various active components, passive components, circuits, and connectors for electrical connections to realize control units.
[0010] Multiple circuit boards can be incorporated into the display device to implement the power supply and control unit. These circuit boards can be electrically connected via connectors.
[0011] Because connectors occupy a certain volume, gaps may form between the circuit board and the connector when one circuit board is electrically connected to another.
[0012] Foreign objects such as dust can enter this gap. If foreign objects accumulate in the gap between the circuit board and the connector, they can cause breaks in the electrical connection or other electrical faults.
[0013] Specifically, when the display device is used continuously, foreign objects may continue to enter such gaps, which may cause the display device to malfunction or fail. In severe cases, flammable foreign objects may even cause a fire in the display device.
[0014] Depending on the layout of the circuit board, this gap can be formed in a direction parallel to the direction of gravity.
[0015] Foreign objects may fall due to gravity and may easily enter the gaps formed in the direction parallel to gravity. Foreign objects that continue to enter and accumulate in the gaps may adversely affect the display device as described above.
[0016] Therefore, there is a need to develop display devices with structures that can prevent foreign objects such as dust from entering the gaps formed at the connection points between circuit boards.
[0017] Therefore, the object of this disclosure is to provide a display device including a structure with a protective member capable of preventing foreign objects from entering the gap formed at the connection portion between circuit boards.
[0018] Another object of this disclosure is to provide a display device including a structure with a protective member capable of preventing the entry of foreign objects such as dust that fall into such a gap due to gravity.
[0019] The purposes of this disclosure are not limited to those mentioned above, and other purposes and advantages not explicitly stated will be understood from the following description and will become more apparent from embodiments of this disclosure. Furthermore, it will be apparent that the purposes and advantages of this specification can be achieved by the means and combinations thereof set forth in the claims.
[0020] According to an embodiment, a display device may include: a display panel; a metal plate disposed at the rear of the display panel; a first circuit board disposed at the rear of the metal plate; a second circuit board disposed at the rear of the metal plate and above the first circuit board; a third circuit board disposed at the rear of the metal plate and electrically connected to the first and second circuit boards; a first connector electrically connected to the first and third circuit boards; and a protective member coupled to the first and third circuit boards, a portion of which is disposed above a separation space formed between the first and third circuit boards.
[0021] One end of the protective component can be adhered to a surface of the third circuit board and the other end can be adhered to a surface of the first circuit board.
[0022] The protective component can be configured to cover the separation space formed between the first and third circuit boards from above, thereby preventing foreign objects falling due to gravity from entering the separation space.
[0023] According to an embodiment, a display device may include: a metal plate; a first circuit board disposed at the rear of the metal plate; a second circuit board disposed at the rear of the metal plate and above the first circuit board; a third circuit board disposed at the rear of the metal plate and electrically connected to the first and second circuit boards; a first connector electrically connected to the first and third circuit boards; and a protective member coupled to the first and third circuit boards and configured to cover from above the separation space formed between the first and third circuit boards.
[0024] According to an embodiment, the display device may include a display panel disposed in front of a metal plate, a polarizer disposed in front of the display panel, a cover window disposed in front of the polarizer, and a back plate disposed at the rear of the display panel and in front of the metal plate.
[0025] In the display device according to the present disclosure, a protective member can be connected to a first circuit board and a third circuit board, and a portion of the protective member is disposed above the separation space formed between the first circuit board and the third circuit board.
[0026] The protective component can be placed above the separation space, which has an open upper side and a closed lower side. This structure effectively prevents foreign objects, such as dust, from entering the separation space due to gravity as they fall from the top of the display device.
[0027] Therefore, the protective components can prevent foreign objects from entering the separation space, thereby effectively reducing or preventing display device malfunctions or failures caused by the accumulation of foreign objects in the separation space, and improving the durability of the display device.
[0028] Furthermore, in the display device according to this disclosure, the protective member can be manufactured in a flat state and easily bent for installation into the display device during the assembly process. This structure effectively prevents foreign objects from entering the separation space without introducing complex structures or processes. Therefore, the display device can be significantly improved while reducing manufacturing costs.
[0029] Furthermore, in the display device according to this disclosure, the use of protective components can suppress the entry of foreign objects into the interior of the device, thereby reducing or preventing malfunctions or increased power consumption caused by foreign objects, and enabling a low-power display device.
[0030] In addition to the effects described above, other beneficial effects of this disclosure will be provided as the disclosure is described in detail.
[0031] Other systems, methods, features, and advantages will be apparent or become apparent to those skilled in the art upon reading the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages are included in this specification, fall within the scope of this disclosure, and are protected by the appended claims.

For clarity, illustrative purposes, the relative dimensions and depictions of these elements may be exaggerated. Detailed Implementation
[0042] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. In the following description, detailed descriptions of well-known functions will be omitted or provided briefly where such detail would unnecessarily obscure the gist of the inventive concept. The described progression of processing steps and / or operations is exemplary; however, the order of steps and / or operations is not limited to the order set forth herein and can be varied as is known in the art, except where the steps and / or operations must occur in a specific order. The same reference numerals always denote the same elements. The names of the various elements used in the following description are chosen solely for convenience of writing the specification and may therefore differ from the names used in actual products.
[0043] The foregoing objects, features, and advantages of this disclosure will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement the technical concepts of this disclosure. Where a detailed description of well-known technologies related to this disclosure unnecessarily obscures their essence, it will be omitted or may be provided briefly. Hereinafter, embodiments of this disclosure will be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings are used to denote the same or similar components.
[0044] Although terms such as "first" and "second" are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from another, and unless otherwise explicitly stated, the first component can be the second component, and vice versa.
[0045] Throughout this specification, unless otherwise expressly stated, each component may be singular or plural. Throughout the accompanying drawings and detailed description, unless otherwise stated, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustrative purposes, and convenience, the relative sizes and depictions of these elements may be exaggerated.
[0046] Unless the context clearly indicates otherwise, singular expressions used in this specification include plural expressions. In this application, terms such as “comprising” or “including” should not be construed as necessarily including all components or steps listed in the specification; some components or steps may be excluded, or additional components or steps may be included.
[0047] Throughout this specification, unless otherwise stated, the term “A and / or B” means A, B, or both A and B, and unless otherwise stated, the term “C to D” means C or greater and D or less.
[0048] Any implementation described as an "example" in this document is not necessarily to be interpreted as preferred or advantageous over other implementations.
[0049] Furthermore, when referring to any size, relative size, etc., it should be assumed that even without a specific description, the numerical value or corresponding information (e.g., grade, range, etc.) of an element or feature includes the tolerance or error range that may be caused by various factors (e.g., process factors, internal or external influences, noise, etc.). In addition, the term "may" fully encompasses all the meanings of the term "can".
[0050] In the description of various embodiments of this disclosure, when describing positional relationships, for example, when the positional relationship between two parts is described as such as "above," "over," "below," and "beside," one or more other parts may be located between the two parts, unless more restrictive terms such as "just" or "directly" are used. For example, when one element or layer is arranged "on" another element or layer, a third element or layer may be inserted therebetween.
[0051] When describing temporal relationships, if the time sequence is described as such as "after", "following", "next", and "before", discontinuous situations may be included unless more restrictive terms such as "just", "immediately", or "directly" are used.
[0052] Furthermore, unless otherwise specified, when a component or layer is “connected,” “joined,” or “adhered” to another component or layer, it means that the component or layer can be directly connected or adhered to the other component or layer, or indirectly connected or adhered to the other component or layer, with one or more intermediate components or layers “set” or “inserted” between these components or layers. This should be understood to mean that the components can be configured to be in direct contact with each other, or not in direct contact with each other.
[0053] Those skilled in the art will recognize that various modifications and variations can be made to the embodiments of this disclosure without departing from the technical spirit or scope thereof. Therefore, this disclosure is intended to cover such modifications and variations as long as they fall within the scope of the appended claims and their equivalents.
[0054] Figure 1 This is a perspective view of a display device according to an embodiment. Figure 2 This is a front view of the display device according to an embodiment. Figure 3 This is a rear view of the display device according to an embodiment.
[0055] In this specification, "front" refers to the direction from the back panel 630 to the cover window 620, and the opposite direction is referred to as "rear".
[0056] The display device according to the embodiment can be used, for example, in a state of being fixedly connected to another object. The display device according to the embodiment can be, for example, a vehicle display device installed in front of the driver's seat in a vehicle.
[0057] like Figure 2 and Figure 3 As shown, the display device can be used while attached to an object and held in an upright position.
[0058] Therefore, since the display device is used in a state of being fixedly connected to an object, its upper and lower sides can be distinguished.
[0059] Reference Figure 3 In this specification, "upward direction" refers to the direction from the first circuit board 310 toward the second circuit board 320, and the opposite direction is referred to as "downward direction." The terms "up" and "down" as used in this specification can be interpreted accordingly.
[0060] Figure 4 This is an exploded perspective view of the display device according to an embodiment. In the following text, reference will first be made to... Figure 4 Describe the overall structure of the display device.
[0061] The display device may include a display panel 100, a metal plate 200, and a panel unit 300.
[0062] The display panel 100 can display images or videos. In the vehicle display device, the displayed images may include navigation information required for driving, videos captured by cameras installed in the vehicle, or various other content required by the driver or passengers.
[0063] The metal plate 200 can be disposed behind the display panel 100 and the back panel 630. The metal plate 200 can be formed into a thin shape to manufacture a slim display device. The rear surface of the metal plate 200 can be exposed to air, thereby allowing heat to be transferred to the atmosphere.
[0064] The metal plate 200 can protect the display panel 100 and the back plate 630, and can also be used as a heat sink to dissipate the heat generated from the display panel 100 and the back plate 630 to the outside to cool the display panel 100 and the back plate 630.
[0065] For effective heat dissipation, the metal plate 200 can be formed of a material with high thermal conductivity. The metal plate 200 can be made of, for example, aluminum or an alloy including aluminum.
[0066] The board unit 300 may be disposed behind the metal plate 200. The board unit 300 may include means for supplying power to the display device and may implement a control unit for controlling the operation of the display device.
[0067] The circuit board may include various active components, passive components, circuits, and connectors for electrical connections to realize a control unit. The board unit 300 may include a first circuit board 310, a second circuit board 320, and a third circuit board 330.
[0068] The first circuit board 310 and the second circuit board 320 of the board unit 300 can be connected to a connection structure disposed on an object on which the display device is mounted, for example, using a connecting mechanism such as screws. The two ends of the third circuit board 330 can be connected to the first circuit board 310 and the second circuit board 320, respectively.
[0069] The first circuit board 310 can be disposed behind the metal plate 200 and located below the display device. The first circuit board 310 can, for example, connect the vehicle's main control module to the second circuit board 320 and supply power to the second circuit board 320.
[0070] In addition, the first circuit board 310 can perform timing control on the communication signals of the board unit 300. The first circuit board 310 may include various active components, passive components, and electronic circuits to perform these functions.
[0071] The second circuit board 320 can be disposed behind the metal plate 200 and positioned above the first circuit board 310. The second circuit board 320 can be electrically connected to the first circuit board 310 via a third circuit board 330. The second circuit board 320 can control various operations of the display device.
[0072] The second circuit board 320 may include means for communicating with external devices such as a camera or a vehicle’s main control module, means for driving the display panel 100 to display images or videos, circuitry, and various active and passive components.
[0073] The first circuit board 310 and the second circuit board 320 can be configured as rigid circuit boards that do not deform due to external forces.
[0074] The third circuit board 330 may be disposed behind the metal plate 200 and electrically connected to the first circuit board 310 and the second circuit board 320. The third circuit board 330 may be formed of a flexible material and serve as a cable for electrically connecting the first circuit board 310 and the second circuit board 320.
[0075] Because the third circuit board 330 is made of a flexible material, the positioning and configuration of the first circuit board 310 and the second circuit board 320 can be freely adjusted. The third circuit board 330 may include various active components, passive components, and electronic circuits to perform the above-mentioned functions.
[0076] A display device according to one embodiment may include a first connector 410 and a second connector 420. The first connector 410 may electrically connect a first circuit board 310 and a third circuit board 330.
[0077] The first connector 410 may be formed to slightly protrude from the rear surface of the first circuit board 310 and may have pins for electrical connection with the third circuit board 330. These pins may be arranged in multiples and with small gaps between them.
[0078] Furthermore, multiple first connectors 410 can be provided, and each of the multiple connectors can be connected to the third circuit board 330. Therefore, multiple third circuit boards 330 can be provided corresponding to the number of first connectors 410.
[0079] The second connector 420 can be connected to the second circuit board 320 and electrically connected to the third circuit board 330. The structure of the second connector 420 can be similar to that of the first connector 410.
[0080] The second connector 420 may be formed to slightly protrude from the rear surface of the second circuit board 320 and may have pins for electrical connection with the third circuit board 330. These pins may be arranged in multiples and with small gaps between them.
[0081] Furthermore, multiple second connectors 420 can be configured, and each of the multiple connectors can be connected to a third circuit board 330.
[0082] According to an embodiment, the display device may include a polarizing plate 610, a cover window 620, and a back plate 630.
[0083] The polarizing plate 610 can be positioned in front of the display panel 100 and behind the cover window 620. The polarizing plate 610 can convert light emitted from the display panel 100 into circularly polarized light. The polarizing plate 610 can improve the outdoor visibility and contrast of the image displayed on the display panel 100 by reducing or preventing the reflection of external light.
[0084] The cover window 620 can be positioned in front of the polarizing plate 610 and at the very front of the display device to form the appearance of the display device.
[0085] Cover window 620 may be located in front of display panel 100 to protect display panel 100. Cover window 620 may be formed of transparent material so that light emitted from display panel 100 can pass through cover window 620.
[0086] The cover window 620 may be made of transparent glass or transparent plastic, but is not limited to these materials.
[0087] The cover window 620 can be formed to be relatively thick to protect the components behind it and maintain the rigidity of the entire display device, thereby reducing or preventing it from being easily deformed by external impacts.
[0088] The back plate 630 can be positioned behind the display panel 100 and in front of the metal plate 200. The back plate 630 can support the thin display panel 100, strengthen the rigidity of the display panel 100, and reduce or prevent deformation of the display panel 100.
[0089] According to an embodiment, the back panel 630 may include a light source for irradiating light onto the display panel 100.
[0090] The display device may include an adhesive layer for bonding corresponding components. According to one embodiment, the display device may include a first adhesive layer 640 and a second adhesive layer 650. However, this disclosure is not limited thereto, and the number of adhesive layers may be three or more as needed.
[0091] The first adhesive layer 640 can be disposed between the back plate 630 and the metal plate 200, and can bond the back plate 630 and the metal plate 200 together. The second adhesive layer 650 can be disposed between the polarizing plate 610 and the cover window 620, and can bond the polarizing plate 610 and the cover window 620 together.
[0092] The first adhesive layer 640 and the second adhesive layer 650 can be provided in the form of a film or sheet, and can be formed of an adhesive material. Specifically, since light emitted from the display panel 100 typically passes through the second adhesive layer 650, the second adhesive layer 650 can be formed of a transparent material with high light transmittance.
[0093] For example, the first adhesive layer 640 and the second adhesive layer 650 may be formed of or include a material with strong adhesion, such as an optically transparent adhesive (OCA), an optically transparent resin (OCR), or a pressure-sensitive adhesive (PSA).
[0094] Specifically, the second adhesive layer 650 may be formed of or include OCA or OCR, which are transparent materials with high light transmittance.
[0095] Figure 5 This is a partial side view of the display device according to an embodiment. Figure 5 The arrow shown indicates the direction of gravity. Figure 6 yes Figure 5 A magnified view of a portion of the image.
[0096] like Figure 3 and Figure 5As shown, when the display device is assembled for conventional use, it can be oriented in a direction parallel to gravity when viewed from the side.
[0097] In this configuration, the first circuit board 310 can be disposed at the lower part of the display device, and the second circuit board 320 can be disposed at the upper part of the display device. Therefore, the first circuit board 310 and the second circuit board 320 can be disposed at the lower and upper sides respectively in a direction parallel to the direction of gravity.
[0098] The third circuit board 330 can be arranged such that its length direction is aligned with the vertical direction of the display device. Here, when the third circuit board 330 is connected to the first connector 410 protruding from the rear surface of the first circuit board 310, a separation space 1000 can be formed between the first circuit board 310 and the third circuit board 330.
[0099] This is because the third circuit board 330 is not adhered to the surface of the first circuit board 310, but is connected to the first connector 410 protruding from the first circuit board 310, while being spaced apart from the surface of the first circuit board 310 to a certain extent. Due to this structure, the aforementioned separation space 1000 can be formed between the first circuit board 310 and the third circuit board 330.
[0100] The separation space 1000 can be defined as having an open upper side and a lower side closed by the first connector 410. Foreign objects such as dust or metal particles floating in the air may fall downwards in the direction of gravity.
[0101] Therefore, such foreign objects may fall into the separation space 1000 with its open upper side and may accumulate therein. When foreign objects are introduced and accumulate in the separation space 1000, they may cause problems such as the disconnection of electrical connections.
[0102] Specifically, when the display device is used continuously, foreign objects may continue to enter the separation space 1000, which may cause the display device to malfunction or fail, and in extreme cases, flammable foreign objects may cause a fire in the display device.
[0103] Foreign objects from the external environment fall due to gravity, and such gravity-driven matter can easily enter the separation space 1000, which is open in a direction parallel to gravity. As described above, foreign objects that continuously enter and accumulate in the separation space 1000 may have an adverse effect on the display device.
[0104] Specifically, when metal particles enter the separation space 1000, high-density particles may easily fall into the space due to gravity. Since such particles are conductive foreign objects, their presence and movement may pose a significant risk of causing malfunctions or damage to the display device. Therefore, it is necessary to prevent such metal particles from being introduced into the separation space 1000.
[0105] Therefore, a structure is needed that can prevent foreign objects from entering the separation space 1000.
[0106] Furthermore, a separation region similar to the previously mentioned separation space 1000 can be formed in the structure connecting the second circuit board 320, the second connector 420, and the third circuit board 330. However, in this case, the upper side of the separation region is closed by the second connector 420, while the lower side is open.
[0107] Therefore, foreign objects falling due to gravity are unlikely to accumulate in the separation area because the bottom is open. Thus, the accumulation of foreign objects in the separation area formed by the connection of the second circuit board 320, the second connector 420, and the third circuit board 330 is unlikely to be a problem.
[0108] Therefore, a more detailed description of the structure for reducing or preventing the accumulation of foreign matter in the separation space 1000 formed by the connection of the first circuit board 310, the first connector 410 and the third circuit board 330 will be provided below.
[0109] According to an embodiment, the display device may include a protective member 500. The protective member 500 may be connected to the first circuit board 310 and the third circuit board 330, and a portion of the protective member 500 is disposed above the separation space 1000 formed between the first circuit board 310 and the third circuit board 330.
[0110] The number of protective members 500 can be set corresponding to the number of first circuit boards 310 and third circuit boards 330 connected to each other. Since the accompanying drawings in this specification show two sets of first circuit boards 310 and third circuit boards 330 connected to each other, two protective members 500 can be provided. Of course, when there are three or more sets of first circuit boards 310 and third circuit boards 330 connected to each other, three or more protective members 500 can also be provided.
[0111] The protective member 500 can be positioned above the separation space 1000, which has an open upper side and a closed lower side. This structure allows the protective member 500 to effectively reduce or prevent foreign objects (such as dust and metal particles falling from the top of the display device due to gravity) from entering the separation space 1000.
[0112] Therefore, the protective component 500 can prevent foreign objects from entering the separation space 1000, thereby effectively reducing or preventing operational malfunctions or damage to the display device caused by the accumulation of such substances, and thereby improving the durability of the display device.
[0113] The protective member 500 can be formed as a thin film, which can be in an unbent state during manufacturing. However, when assembling the display device, the protective member 500 can be bent and positioned above the separation space 1000, thereby preventing foreign objects falling due to gravity from entering through the open upper side of the separation space 1000.
[0114] The protective member 500 may be formed as a thin film, at least a portion of which is bent into a curved shape and disposed above the separation space 1000.
[0115] For example, such as Figure 5 As shown, the curved portion of the protective member 500 can be disposed in the space formed between the metal plate 200 and the third circuit board 330 facing each other. That is, at least a portion of the protective member 500 can be disposed between the third circuit board 330 and the metal plate 200.
[0116] Furthermore, the bending structure of the protective member 500 does not need to be uniform in the lateral direction of the first circuit board 310. That is, when viewed in the lateral direction of the first circuit board 310, the bending structure of the protective member 500 can be set at a certain angle.
[0117] Due to this inclined arrangement, such as Figure 5 As shown, when viewed from the side, the curved portion of the protective member 500 may appear to have different widths at different points.
[0118] The protective member 500 can be manufactured without any bending portions and has portions that bend during the assembly of the display device. For example, a rigid protective member 500 that is difficult to deform under external force can be heated during the bending process to become slightly flexible and bend under external force.
[0119] Subsequently, the protective component 500 cools and returns to its rigid material state, thereby stably maintaining its designed position and effectively reducing or preventing foreign objects from entering the separation space 1000.
[0120] Therefore, the protective component 500 can be made of a plastic material that meets the requirements of the assembly process. For example, the protective component 500 can be made of glass fiber reinforced epoxy resin (FR4), polyethylene terephthalate (PET), or polyimide with the desired material properties.
[0121] Specifically, in the embodiments, glass fiber reinforced epoxy resin is a suitable material for protective component 500 due to its electrical insulation, flame retardancy, high heat resistance and mechanical strength.
[0122] The protective member 500 needs to continuously maintain at least a portion of its structure positioned above the separation space 1000. Therefore, the protective member 500 must be securely attached to the other components of the display device.
[0123] To achieve this, in one embodiment, one end of the protective member 500 can be adhered to a surface of the third circuit board 330, and the other end can be adhered to a surface of the first circuit board 310. This structure can be achieved by bending a portion of the protective member 500.
[0124] Specifically, the protective member 500 can be bent from a portion that is adhered to a surface of the third circuit board 330, and its end can extend above the upper side of the first circuit board 310 and adhere to a surface of the first circuit board 310.
[0125] Reference Figure 6 One end of the protective member 500 can be adhered to the surface of the third circuit board 330 facing the first circuit board 310, and the other end can be adhered to the surface of the first circuit board 310 opposite to the surface facing the third circuit board 330.
[0126] This structure allows the upper side of the separation space 1000 formed between the facing surfaces of the first circuit board 310 and the third circuit board 330 to be completely surrounded by the curved portion of the protective member 500.
[0127] As a result, foreign objects that are lowered by gravity cannot enter the open upper side of the separation space 1000, thus significantly and effectively inhibiting their entry into and accumulation in the separation space 1000.
[0128] In one embodiment, the first connector 410 may be coupled to the first circuit board 310 to protrude from one of its surfaces. Additionally, a third circuit board 330 may be coupled to the connector to be spaced apart from the first circuit board 310.
[0129] Therefore, a separation space 1000 with an open upper side and a lower side closed by the first connector 410 can be formed between the third circuit board 330 and the first circuit board 310. Of course, the size of the separation space 1000 can be reduced to some extent by modifying the structure of the first circuit board 310, the third circuit board 330 and the first connector 410; however, it is difficult to completely eliminate the separation space 1000, and therefore the separation space 1000 may still exist.
[0130] Therefore, a structure is needed to prevent foreign objects from entering the separation space 1000, and in one embodiment, this requirement is met by placing a portion of the protective member 500 above the separation space 1000.
[0131] In other words, the protective member 500 is configured to cover the separation space 1000 formed above the space between the first circuit board 310 and the third circuit board 330 to prevent foreign objects falling due to gravity from entering the separation space 1000.
[0132] Figure 7 This is a view showing the third circuit board 330 and the protective member 500 according to an embodiment. Figure 8 It is shown Figure 7 A perspective view of the protective component 500 in a bent state.
[0133] The third circuit board 330 may have connection pins 331 formed for electrical connection with pins on the first connector 410. The connection pins 331 may be provided in a shape and number corresponding to the pins of the first connector 410.
[0134] The unbent portion of the protective member 500 can be adhered to the surface of the first circuit board 310. In an embodiment, the adhesive portion of the protective member 500 may include an avoidance area to bypass the connection pin 331 when adhered to a surface of the first circuit board 310. The assembly process of the protective member 500 in the display device is as follows.
[0135] First, such as Figure 7 As shown, the protective member 500, in a flat, unbent state, can be adhered to the surface of the third circuit board 330. Here, one end of the protective member 500, excluding the part to be bent, can be adhered to the surface of the third circuit board 330.
[0136] Next, as Figure 8 As shown, during the assembly process of the display device, the protective member 500 can be heated to become slightly flexible, and a portion of the protective member 500 can be bent using a bending device or by an operator.
[0137] Then, the other end of the protective member 500 can be adhered to the surface of the first circuit board 310. When the protective member 500 is adhered to the first circuit board 310, the open upper side of the separation space 1000 formed between the first circuit board 310 and the third circuit board 330 can be surrounded by the protective member 500.
[0138] In this embodiment, the protective member 500 can be manufactured in a flat state and easily installed into the display device during the assembly process. This structure effectively prevents foreign objects from entering the separation space 1000 without introducing complex structures or processes into the display device. Therefore, the display device can be significantly improved while reducing manufacturing costs.
