Description
Cover module and display device having the same
[0001] The present invention relates to a cover module capable of dissipating heat by preventing heat generated from an electronic component that applies a driving signal to a display panel from being conducted to the display panel, and to a display device including the cover module.
[0002] As the information society develops, the demand for display devices is also increasing in various forms, and in response to this, recent display devices include liquid crystal display devices (LCD), field emission display devices (FED), plasma display panels (PDP), and electroluminescence devices.
[0003] Currently, the major commercially available display devices are LCDs and OLEDs (Organic Light Emitting Diodes). However, LCDs cannot emit light on their own, requiring a backlight unit to illuminate the display, making flexible implementation difficult.
[0004] Unlike LCDs, OLEDs are self-luminous and require no backlight unit, making them easy to implement in flexible forms and enabling the creation of diverse display devices. Furthermore, the lack of a backlight unit offers advantages in response speed, viewing angle, and other aspects, making them a promising next-generation display.
[0005] Furthermore, displays have been increasing in size in recent years, necessitating measures to reduce the weight and thickness of display devices while also reducing manufacturing costs. Furthermore, the importance of display device external design to meet consumer needs is growing.
[0006] Additionally, as displays become larger, a phenomenon called "brightness lines" can occur, where certain areas appear brighter and the entire screen appears uneven. This can also stem from heat dissipation issues associated with larger displays.
[0007] Therefore, as displays become larger, a means is required to improve the performance of the display device by solving the heat dissipation problem, while reducing the weight and making the display device lighter.
[0008] The present invention relates to a cover module and a display device having the same, and more specifically, to a cover module capable of dissipating heat by preventing heat generated from an electronic component that applies a driving signal to a display panel from being conducted to the display panel, and a display device having the same.
[0009] In addition, the purpose is to provide a cover module capable of heat dissipation by forming a gap between an inner plate covering the back surface of a display panel and an outer cover on which electronic components are mounted, and a display device including the cover module.
[0010] In addition, the purpose is to provide a cover module and a display device including the same that can minimize heat conduction to a display panel through an inner plate formed of aluminum material having excellent thermal conductivity.
[0011] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0013] The above outer cover may include a stepped portion formed by bending backward.
[0014] The above outer cover may include a heat dissipation portion that is formed by extending from the step portion and forming the gap.
[0015] The above heat dissipation part can be spaced apart from the back surface of the inner plate by a distance of 3 mm or more to form the gap.
[0016] The above heat dissipation part may include a joining groove formed by being sunken so as to be in contact with the back surface of the inner plate, and the inner plate may include a joining projection formed by protruding from the back surface and inserted into the joining groove.
[0017] The above step portion can be formed in the left and right directions.
[0018] The above inner plate may include aluminum material.
[0019] The above fixed frame may include a first fastening protrusion formed by protruding from the back surface, and the inner plate and the outer cover may include a structure that is fitted into and coupled to the first fastening protrusion.
[0020] The above fixed frame may include a first fastening protrusion and a second fastening protrusion formed spaced apart from each other in the vertical direction, and the outer cover may include a structure that is fitted into and coupled to the second fastening protrusion.
[0021] It may include a cover frame that is coupled to the back surface of the outer cover and covers the side of the display panel.
[0022] The above cover frame may include aluminum material.
[0023] It may further include a back cover that is coupled to the back surface of the cover frame and covers the back surface of the outer cover.
[0024] A display device is provided, comprising: a display panel on which an image is output; and a cover module covering the display panel and preventing heat generated from an electronic component that applies a driving signal to the display panel from being conducted to the display panel, wherein the cover module comprises: a fixed frame having a rim shape that is in contact with a rear circumference of the display panel; an inner plate that is coupled to a rear surface of the fixed frame and covers the rear surface of the display panel; and an outer cover that is coupled to a rear surface of the fixed frame and covers the rear surface of the inner plate, wherein the outer cover is bent to form a gap by being spaced apart from a rear surface of the inner plate by a predetermined distance.
[0025] The above inner plate may include aluminum material.
[0026] The above display panel may include an OLED panel.
[0027] The cover module according to the present invention and the display device including the same can dissipate heat by preventing heat generated from an electronic component that applies a driving signal to the display panel from being conducted to the display panel.
[0028] Additionally, heat dissipation can be achieved by forming a gap between the inner plate covering the back of the display panel and the outer cover on which electronic components are mounted.
[0029] Additionally, heat conduction to the display panel can be minimized through the inner plate formed of aluminum material with excellent thermal conductivity.

[0040] When a component is referred to as being "connected" or "connected" to another component, it should be understood that it may be directly connected or connected to that other component, but that there may be other components intervening. Conversely, when a component is referred to as being "directly connected" or "connected" to another component, it should be understood that there are no other components intervening.
[0041] Singular expressions include plural expressions unless the context clearly indicates otherwise.
[0042] In this application, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.
[0043] Figure 1 is a block diagram for explaining each component of a display device (100). The display device (100) may include a broadcast receiving unit (110), an external device interface unit (171), a network interface unit (172), a storage unit (140), a user input interface unit (173), an input unit (130), a control unit (180), a display module (150), an audio output unit (160), and / or a power supply unit (190).
[0044] The broadcast receiving unit (110) may include a tuner unit (111) and a demodulator unit (112).
[0045] Meanwhile, unlike the drawing, the display device (100) may include only the external device interface unit (171) and the network interface unit (172) among the broadcast receiving unit (110), the external device interface unit (171), and the network interface unit (172). That is, the display device (100) may not include the broadcast receiving unit (110).
[0046] The tuner unit (111) can select a broadcast signal corresponding to a channel selected by the user or all previously stored channels among broadcast signals received through an antenna (not shown) or a cable (not shown). The tuner unit (111) can convert the selected broadcast signal into an intermediate frequency signal or a baseband video or audio signal.
[0047] For example, the tuner unit (111) can convert the selected broadcast signal into a digital IF signal (DIF) if it is a digital broadcast signal, and can convert it into an analog baseband video or audio signal (CVBS / SIF) if it is an analog broadcast signal. That is, the tuner unit (111) can process a digital broadcast signal or an analog broadcast signal. The analog baseband video or audio signal (CVBS / SIF) output from the tuner unit (111) can be directly input to the control unit (180).
[0048] Meanwhile, the tuner unit (111) can sequentially select broadcast signals of all stored broadcast channels through the channel memory function among the received broadcast signals and convert them into intermediate frequency signals or baseband video or audio signals.
[0049] Meanwhile, the tuner unit (111) may be equipped with multiple tuners to receive broadcast signals of multiple channels. Alternatively, a single tuner that simultaneously receives broadcast signals of multiple channels is also possible.
[0050] The demodulation unit (112) can perform a demodulation operation by receiving a digital IF signal (DIF) converted by the tuner unit (111). The demodulation unit (112) can output a stream signal (TS) after performing demodulation and channel decoding. At this time, the stream signal can be a signal in which a video signal, an audio signal, or a data signal is multiplexed.
[0051] The stream signal output from the demodulation unit (112) can be input to the control unit (180). The control unit (180) can perform demultiplexing, image / audio signal processing, etc., and then output an image through the display module (150) and output an audio through the audio output unit (160).
[0052] The sensing unit (120) refers to a device that detects changes within the display device (100) or external changes. For example, it may include at least one of a proximity sensor, an illumination sensor, a touch sensor, an infrared sensor (IR sensor), an ultrasonic sensor, an optical sensor (e.g., a camera), a voice sensor (e.g., a microphone), a battery gauge, and an environmental sensor (e.g., a hygrometer, a thermometer, etc.).
[0053] The control unit (180) can check the status of the display device (100) based on the information collected from the sensing unit (120), and if a problem occurs, can notify the user of it or control it to maintain the best status by adjusting it on its own.
[0054] In addition, the content, picture quality, size, etc. of the image provided to the display module (150) can be controlled differently depending on the viewer detected by the sensing unit (120) or the surrounding lighting, etc., to provide an optimal viewing environment. As smart TVs advance, the functions installed in the display device (100) are increasing, and the sensing unit (120) is also increasing along with this.
[0055] The input unit (130) may be provided on one side of the main body of the display device (100). For example, the input unit (130) may include a touch pad, a physical button, etc. The input unit (130) may receive various user commands related to the operation of the display device (100) and transmit a control signal corresponding to the input command to the control unit (180).
[0056] Recently, as the size of the bezel of the display device (100) has become smaller, the number of display devices (100) with a minimal input unit (130) in the form of a physical button exposed to the outside has increased. Instead, a minimum number of physical buttons are positioned on the back or side, and user input can be received through a remote control device (200) via a touchpad or a user input interface unit (173) described later.
[0057] The storage unit (140) may store programs for each signal processing and control within the control unit (180), or may store signal-processed video, audio, or data signals. For example, the storage unit (140) may store application programs designed for the purpose of performing various tasks that can be processed by the control unit (180), and may selectively provide some of the stored application programs upon request from the control unit (180).
[0058] Programs stored in the storage unit (140) are not particularly limited as long as they can be executed by the control unit (180). The storage unit (140) may also perform a function for temporarily storing video, audio, or data signals received from an external device through the external device interface unit (171). The storage unit (140) may store information regarding a specific broadcast channel through a channel memory function such as a channel map.
[0059] Although the storage unit (140) of FIG. 1 is provided separately from the control unit (180), the scope of the present invention is not limited thereto, and the storage unit (140) may be included within the control unit (180).
[0060] The storage unit (140) may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) or non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).
[0061] The display module (150) can generate a driving signal by converting a video signal, data signal, OSD signal, control signal, etc. processed by the control unit (180) or a video signal, data signal, control signal, etc. received from the interface unit (171).
[0062] And the display module (150) may include an OLED module according to an embodiment of the present invention described below.
[0063] The display module (150) can be a flexible display, and may also be a 3D display. The 3D display module (150) can be divided into a glasses-free type and a glasses type.
[0064] The display device (100) may include a display module (150) that occupies most of the front surface area and a case that covers the rear side of the display module (150) and packages the display module (150).
[0065] Previously, LCDs were primarily used because they had difficulty emitting light on their own, so they relied on a backlight unit for light. A backlight unit is a device that evenly distributes light from a light source to the liquid crystal display (LCD) located at the front. As backlight units have become thinner, thinner LCDs have become possible. However, it is difficult to implement a backlight unit using a flexible material, and when a backlight unit is bent, it becomes difficult to supply light evenly to the LCD, causing screen brightness to fluctuate.
[0066] On the other hand, in the case of LEDs (Light Emitting Diodes) or OLEDs (Organic Light Emitting Diodes), since each element forming a pixel emits light on its own, it can be implemented to be curved without using a backlight unit. In addition, since each element emits light on its own, even if the positional relationship with neighboring elements changes, its own brightness is not affected, so a curved display module (150) can be implemented.
[0067] OLEDs made their full-fledged debut in the mid-2010s and are rapidly replacing LCDs in the small- and medium-sized display market. OLEDs utilize the self-luminous phenomenon, where fluorescent organic compounds emit light when current flows through them. Their image quality response speed is faster than that of LCDs, resulting in virtually no afterimages when displaying video.
[0068] OLED uses three types of fluorescent organic compounds with self-luminous functions: red, green, and blue. It is a luminescent display product that utilizes the phenomenon in which electrons injected from the cathode and anode and positively charged particles combine within the organic material to emit light on their own, so there is no need for a backlight that reduces color.
[0069] The display module (150) may include a coupling magnet, a first power supply unit, and a first signal module.
[0070] The side of the display module (150) that displays an image may be referred to as the front or front. When the display module (150) displays an image, the side from which the image cannot be observed may be referred to as the rear or back. Meanwhile, the display module (150) is configured as a touch screen and can be used as an input device in addition to an output device.
[0071] The audio output unit (160) receives a signal processed by the control unit (180) and outputs it as voice.
[0072] The interface unit (170) serves as a passageway for various types of external devices connected to the display device (100). The interface unit may include not only a wired method for transmitting and receiving data through a cable, but also a wireless method using an antenna.
[0073] The interface unit (170) may include at least one of a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device equipped with an identification module, an audio I / O (Input / Output) port, a video I / O (Input / Output) port, and an earphone port.
[0074] As an example of a wireless method, the broadcast receiving unit (110) described above may be included, and may include not only broadcast signals but also mobile communication signals, short-range communication signals, wireless Internet signals, etc.
[0075] The external device interface unit (171) can transmit or receive data with a connected external device. To this end, the external device interface unit (171) may include an A / V input / output unit (not shown).
[0076] The external device interface unit (171) can be connected to external devices such as a DVD (Digital Versatile Disk), Blu-ray, game device, camera, camcorder, computer (laptop), set-top box, etc., via wired / wireless connection, and can also perform input / output operations with the external devices.
[0077] In addition, the external device interface unit (171) can establish a communication network with various remote control devices (200), and receive a control signal related to the operation of the display device (100) from the remote control device (200), or transmit data related to the operation of the display device (100) to the remote control device (200).
[0078] The external device interface unit (171) may include a wireless communication unit (not shown) for short-range wireless communication with other electronic devices. Through this wireless communication unit (not shown), the external device interface unit (171) can exchange data with an adjacent mobile terminal. In particular, in mirroring mode, the external device interface unit (171) can receive device information, running application information, application images, etc. from the mobile terminal.
[0079] The network interface unit (172) may provide an interface for connecting the display device (100) to a wired / wireless network, including the Internet. For example, the network interface unit (172) may receive content or data provided by the Internet, a content provider, or a network operator via a network. Meanwhile, the network interface unit (172) may include a communication module (not shown) for connection to a wired / wireless network.
[0080] The external device interface unit (171) and / or the network interface unit (172) may include a communication module for short-range communication such as Wi-Fi (Wireless Fidelity), Bluetooth, Bluetooth Low Energy (BLE), Zigbee, and NFC (Near Field Communication), a communication module for cellular communication such as LTE (long-term evolution), LTE-A (LTE Advance), CDMA (code division multiple access), WCDMA (wideband CDMA), UMTS (universal mobile telecommunications system), and WiBro (Wireless Broadband).
[0081] The user input interface unit (173) can transmit a signal input by the user to the control unit (180), or transmit a signal from the control unit (180) to the user. For example, it can transmit / receive a user input signal such as power on / off, channel selection, screen setting, etc. from a remote control device (200), or transmit a user input signal input from a local key (not shown) such as a power key, a channel key, a volume key, a setting value, etc. to the control unit (180), or transmit a user input signal input from a sensor unit (not shown) that senses a user's gesture to the control unit (180), or transmit a signal from the control unit (180) to the sensor unit.
[0082] The control unit (180) may include at least one processor, and may control the overall operation of the display device (100) using the processor included therein. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an ASIC or another hardware-based processor.
[0083] The control unit (180) can demultiplex a stream input through a tuner unit (111), a demodulator unit (112), an external device interface unit (171), or a network interface unit (172), or process demultiplexed signals to generate and output a signal for video or audio output.
[0084] The image signal processed by the control unit (180) can be input to the display module (150) and displayed as an image corresponding to the image signal. In addition, the image signal processed by the control unit (180) can also be input to an external output device through the external device interface unit (171).
[0085] The voice signal processed in the control unit (180) can be output as sound to the audio output unit (160). In addition, the voice signal processed in the control unit (180) can be input to an external output device through the external device interface unit (171). Although not shown in FIG. 2, the control unit (180) may include a demultiplexing unit, an image processing unit, etc.
[0086] In addition, the control unit (180) can control the overall operation within the display device (100). For example, the control unit (180) can control the tuner unit (111) to select (tuning) a broadcast corresponding to a channel selected by the user or a previously stored channel.
[0087] In addition, the control unit (180) can control the display device (100) by a user command or an internal program input through the user input interface unit (173). Meanwhile, the control unit (180) can control the display module (150) to display an image. At this time, the image displayed on the display module (150) may be a still image or a moving image, and may be a 2D image or a 3D image.
[0088] Meanwhile, the control unit (180) can cause a predetermined 2D object to be displayed within an image displayed on the display module (150). For example, the object can be at least one of a connected web screen (newspaper, magazine, etc.), an EPG (Electronic Program Guide), various menus, widgets, icons, still images, videos, and text.
[0089] Meanwhile, the control unit (180) may modulate and / or demodulate a signal using the Amplitude Shift Keying (ASK) method. Here, the Amplitude Shift Keying (ASK) method may mean a method of modulating a signal by varying the amplitude of a carrier wave according to a data value, or of restoring an analog signal to a digital data value according to the amplitude of the carrier wave.
[0090] For example, the control unit (180) can modulate a video signal using the amplitude shift keying (ASK) method and transmit it through a wireless communication module.
[0091] For example, the control unit (180) can demodulate and process an image signal received through a wireless communication module using the amplitude shift keying (ASK) method.
[0092] Through this, the display device (100) can easily transmit and receive signals with other adjacently placed video display devices without using a unique identifier such as a MAC address (Media Access Control Address) or a complex communication protocol such as TCP / IP.
[0093] Meanwhile, the display device (100) may further include a camera (not shown). The camera can capture images of the user. The camera can be implemented with a single camera, but is not limited thereto, and may also be implemented with multiple cameras. Meanwhile, the camera can be embedded in the display device (100) above the display module (150) or can be separately positioned. Image information captured by the camera can be input to the control unit (180).
[0094] The control unit (180) can recognize the user's location based on the image captured by the camera. For example, the control unit (180) can determine the distance (z-axis coordinate) between the user and the display device (100). In addition, the control unit (180) can determine the x-axis coordinate and y-axis coordinate within the display module (150) corresponding to the user's location.
[0095] The control unit (180) can detect the user's gesture based on the image captured from the camera unit, or the signal detected from the sensor unit, or a combination thereof.
[0096] The power supply unit (190) can supply power to the entire display device (100). In particular, it can supply power to a control unit (180) that can be implemented in the form of a system on chip (SOC), a display module (150) for displaying images, and an audio output unit (160) for outputting audio.
[0097] Specifically, the power supply unit (190) may be equipped with a converter (not shown) that converts AC power into DC power and a Dc / Dc converter (not shown) that converts the level of DC power.
[0098] Meanwhile, the power supply unit (190) receives power from an external source and distributes power to each component. The power supply unit (190) may utilize a method of supplying AC power by directly connecting to an external power source, or may include a power supply unit (190) that can be recharged and used, including a battery.
[0099] The former requires a wired cable connection, making movement difficult or limited. The latter offers freedom of movement, but increases weight and volume by the battery. Charging requires a direct connection to a power cable or a charging cradle (not shown) for a set period of time.
[0100] The charging cradle can be connected to the display device through an externally exposed terminal, or the built-in battery can be charged when brought into proximity using a wireless method.
[0101] The remote control device (200) can transmit user input to the user input interface unit (173). To this end, the remote control device (200) can use Bluetooth, RF (Radio Frequency) communication, infrared (Infrared Radiation) communication, UWB (Ultra-wideband), ZigBee, etc. In addition, the remote control device (200) can receive video, audio, or data signals output from the user input interface unit (173) and display or output the same as audio on the remote control device (200).
[0102] Meanwhile, the above-described display device (100) may be a digital broadcast receiver capable of receiving fixed or mobile digital broadcasts.
[0103] Meanwhile, the block diagram of the display device (100) illustrated in FIG. 1 is only a block diagram for one embodiment of the present invention, and each component of the block diagram may be integrated, added, or omitted depending on the specifications of the display device (100) actually implemented.
[0104] That is, two or more components may be combined into a single component, or a single component may be subdivided into two or more components, as needed. Furthermore, the functions performed by each block are intended to illustrate embodiments of the present invention, and their specific operations or devices do not limit the scope of the present invention.
[0105] FIG. 2 is an exploded view of a display device (100) having a cover module (300) according to one embodiment of the present invention. FIG. 3 is a side cross-sectional view of a display device (100) having a cover module (300) according to one embodiment of the present invention. FIG. 4 is a perspective view of a cover module (300) according to one embodiment of the present invention. FIG. 5 is a view of a cover module (300) according to one embodiment of the present invention as viewed from the rear. FIG. 6 is a side cross-sectional view of a fixing frame (310) in a cover module (300) according to one embodiment of the present invention. FIG. 7 is a drawing for explaining a coupling method of a cover module (300) according to one embodiment of the present invention.
[0106] Hereinafter, in describing a cover module (300) and a display device (100) having a cover module (300) according to one embodiment of the present invention, the left-right direction will be described based on the x-axis direction, the up-down direction will be described based on the y-axis direction, and the forward and rearward direction will be described based on the z-axis direction.
[0107] First, referring to FIG. 2, a display device (100) according to an embodiment of the present invention may include a display panel (210) that outputs an image and a cover module (300) that covers the display panel (210). Here, the display panel (210) may include an OLED (Organic Light Emitting Diodes) panel. As described above, the OLED panel is self-luminous without a backlight unit structure, so it is easy to implement in a flexible manner, and thus has the advantage of being able to implement various forms of the display device (100). In addition, the OLED panel has advantages in response speed, viewing angle, etc. because it does not have a backlight unit structure.
[0108] In addition, the display device (100) according to one embodiment of the present invention can prevent heat generated from an electronic component that applies a driving signal to the display panel (210) through the cover module (300) from being conducted to the display panel (210). This enables heat dissipation, thereby improving the performance of the display device (100). Hereinafter, more specific details regarding this will be described.
[0109] Referring to FIGS. 2 to 4 together, a cover module (300) according to one embodiment of the present invention may include a fixed frame (310), an inner plate (320), and an outer cover (330). First, the fixed frame (310) may be coupled to the rear periphery of the display panel (210). Accordingly, the fixed frame (310) may be formed in a rim shape.
[0110] And the inner plate (320) can be coupled to the back surface of the fixed frame (310) to cover the back surface of the display panel (210). That is, the inner plate (320) can cover the back surface of the display panel (210) and, while being coupled to the fixed frame (310), can serve to support the display panel (210).
[0111] The outer cover (330) can be coupled to the back surface of the fixed frame (310) and serve to cover the back surface of the inner plate (320). In addition, an electronic component that applies a driving signal to the display panel (210) can be mounted on the back surface of the outer cover (330).
[0112] In particular, in a cover module (300) according to one embodiment of the present invention, the outer cover (330) may be bent to form a gap (G) spaced apart from the back surface of the inner plate (320) by a predetermined distance. In addition, heat generated from electronic components may be prevented from being conducted to the display panel (210) through the gap (G).
[0113] More specifically, as illustrated in FIGS. 3 and 4, in a cover module (300) according to one embodiment of the present invention, the outer cover (330) may include a step portion (331) formed by being bent backward (in the z-axis direction). In addition, the outer cover (330) may include a heat dissipation portion (332) formed by extending from the step portion (331) and forming a gap (G).
[0114] That is, the cover module (300) according to one embodiment of the present invention can form a gap (G) between the inner plate (320) covering the back surface of the display panel (210) and the outer cover (330) through the folded shape of the outer cover (330). In addition, the heat generated by the electronic component can be minimized from being directly conducted from the outer cover (330) to the inner plate (320) covering the back surface of the display panel (210) through the gap (G).
[0115] In addition, in the cover module (300) according to one embodiment of the present invention, the heat dissipation portion (332) of the outer cover (330) may be spaced apart from the back surface of the inner plate (320) by a distance of 3 mm or more to form a gap (G). To this end, the angle at which the above-described step portion (331) is bent may be adjusted.
[0116] Here, referring to FIGS. 4 and 5 together, in the cover module (300) according to one embodiment of the present invention, the step portion (331) of the outer cover (330) may be formed in the left-right direction (x-axis direction). This is to form a gap (G) between the back surface of the inner plate (320) and the heat dissipation portion (332) of the outer cover (330), as described above.
[0117] In addition, the cover module (300) according to one embodiment of the present invention can secure structural rigidity through the step portion (331) of the outer cover (330). That is, the step portion (331) formed in the left-right direction (x-axis direction) can prevent distortion or bending, which has the advantage of minimizing external force applied to the display panel (210). In particular, as described above, it can be a structure advantageous in securing rigidity of the display device (100) due to the enlargement of the display panel (210).
[0118] In addition, since the step portion (331) of the outer cover (330) is formed by being bent backward (in the z-axis direction), a gap (G) can be formed with the back surface of the inner plate (320) through the step portion (331). In addition, the gap (G) formed through the step portion (331) can also play a role in preventing heat generated from electronic components from being conducted to the display panel (210), as described above.
[0119] Furthermore, in a cover module (300) according to one embodiment of the present invention, the inner plate (320) covering the back surface of the display panel (210) may include an aluminum material. This is to allow heat transferred from the outer cover (330) to the inner plate (320) to be rapidly diffused within the inner plate (320) itself through the aluminum material, which has excellent thermal conductivity. In addition, through this, heat conducted to the display panel (210) can be minimized.
[0120] In addition, referring to FIGS. 3 to 5 together, in a cover module (300) according to one embodiment of the present invention, a heat dissipation portion (332) may include a joining groove (3321) that is formed by being sunken so as to be in contact with the back surface of an inner plate (320). In addition, the inner plate (320) may include a joining protrusion (321) that is formed by protruding from the back surface and is inserted into the joining groove (3321).
[0121] In addition, in the cover module (300) according to one embodiment of the present invention, the inner plate (320) and the outer cover (330) can be coupled through the above-described coupling groove (3321) and coupling protrusion (321), and the diameter (D) of the coupling protrusion (321) formed for the stability of coupling can be determined. In addition, the coupling groove (3321) can be formed corresponding to the diameter (D) of the coupling protrusion (321).
[0122] Additionally, referring to FIGS. 3 to 6 together, in a cover module (300) according to one embodiment of the present invention, the fixed frame (310) may include a first fastening protrusion (311) that is formed to protrude from the rear surface. In addition, the inner plate (320) and the outer cover (330) may include a structure that is fitted into and coupled to the first fastening protrusion (311). For example, a hole may be formed in the inner plate (320) and the outer cover (330) at a position corresponding to the first fastening protrusion (311) to be fitted into the first fastening protrusion (311).
[0123] In addition, in the cover module (300) according to one embodiment of the present invention, the fixed frame (310) may include a second fastening protrusion (312) formed spaced apart from the first fastening protrusion (311) in the vertical direction (y-axis direction). In addition, the outer cover (330) may include a structure that is fitted and coupled to the second fastening protrusion (312). For example, a hole may be formed in the outer cover (330) at a position corresponding to the second fastening protrusion (312) to be fitted to the second fastening protrusion (312).
[0124] And referring to FIG. 3 and FIG. 7 together, a cover module (300) according to one embodiment of the present invention may include a cover frame (340) that is coupled to the rear periphery of an outer cover (330) and covers a side surface of a display panel (210). Additionally, a cover module (300) according to one embodiment of the present invention may include an adhesive member (360) for bonding the rear edge of the display panel (210) and the cover frame (340).
[0125] In addition, in the cover module (300) according to one embodiment of the present invention, the cover frame (340) may include a structure that is fitted and coupled to a second fastening protrusion (312) formed on the back surface of the fixed frame (310). For example, a hole may be formed in the cover frame (340) at a position corresponding to the second fastening protrusion (312) to be fitted to the second fastening protrusion (312).
[0126] Furthermore, as illustrated in FIG. 6, in the cover module (300) according to one embodiment of the present invention, the protruding length (L1) of the first fastening protrusion (311) of the fixed frame (310) and the protruding length (L2) of the second fastening protrusion (312) may be different. This is so that the cover frame (340) is fitted and coupled to the second fastening protrusion (312) as described above. Accordingly, the protruding length (L2) of the second fastening protrusion (312) may be longer than the protruding length (L1) of the first fastening protrusion (311).
[0127] Here, in the cover module (300) according to one embodiment of the present invention, the cover frame (340) may include an aluminum material. This is to ensure that heat transferred through the outer cover (330) is rapidly diffused within the cover frame (340) itself through the aluminum material, which has excellent thermal conductivity as described above. Furthermore, this minimizes heat transferred to the display panel (210).
[0128] In addition, as illustrated in FIG. 3, the cover frame (340) in the cover module (300) according to one embodiment of the present invention may include an opening (341). This may be effective in reducing the weight of the display device (100) due to the enlargement of the display panel (210) as described above, thereby reducing the weight.
[0129] Likewise, in the cover module (300) according to one embodiment of the present invention, the inner plate (320) or the cover frame (340) may include an aluminum material, which may be effective in reducing the weight of the display device (100) due to the enlargement of the display panel (210).
[0130] Additionally, referring to FIG. 2, a cover module (300) according to one embodiment of the present invention may include a back cover (350) that is coupled to the back surface of a cover frame (340) and covers the back surface of an outer cover (330). Here, the back cover (350) may serve to cover an electronic component mounted on the back surface of the outer cover (330). Furthermore, the back cover (350) may be formed such that an edge thereof is bent forward (in the z-axis direction), and an edge of the back cover (350) may be coupled to the cover frame (340).
[0131] In summary, the cover module according to the present invention and the display device including the same can dissipate heat by preventing heat generated from electronic components that apply driving signals to the display panel from being conducted to the display panel. Furthermore, heat dissipation can be achieved by forming a gap between an inner plate covering the back surface of the display panel and an outer cover on which electronic components are mounted. Furthermore, the inner plate, which is formed of an aluminum material with excellent thermal conductivity, can minimize heat conduction to the display panel.
