Description

Technical Field

[0001] The present invention relates to a display device that enables diverse heat dissipation and appearance design by exposing an optical substrate on which a TFT array layer constituting the back side of a display panel is mounted. Background Technology

[0002] With the development of the information society, the requirements for display devices are also increasing in various forms. Correspondingly, recent display devices include liquid crystal displays (LCD), field emission displays (FED), plasma display panels (PDP), and electroluminescence devices.

[0003] Currently, the main commercially available display devices are represented by LCD and OLED (Organic Light Emitting Diodes). However, in the case of LCD, since it cannot emit light itself, it needs a backlight unit to illuminate it, which presents a challenge in achieving flexibility.

[0004] Unlike LCDs, OLEDs are self-illuminating without a backlight unit structure, offering advantages such as flexibility and the ability to create display devices of various shapes. Furthermore, the absence of a backlight unit structure provides advantages in response speed and viewing angle, making them a promising next-generation display technology.

[0005] Furthermore, the recent trend towards larger displays has created a demand for solutions that can reduce the weight and thickness of display devices and lower manufacturing costs. Moreover, the importance of display device design to meet customer requirements is becoming increasingly apparent. Summary of the Invention

[0035] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the accompanying drawings. Regardless of the reference numerals, the same or similar constituent elements are given the same reference numerals, and repeated descriptions are omitted. The suffixes "module" and "part" used for constituent elements in the following description are assigned or used interchangeably only for ease of writing and do not inherently have a distinguishing meaning or function. Furthermore, when describing embodiments disclosed in this specification, detailed descriptions of related well-known technologies will be omitted if it is determined that such detailed descriptions might unnecessarily obscure the spirit of the embodiments disclosed in this specification. Additionally, the accompanying drawings are only for ease of understanding of the embodiments disclosed in this specification; the technical concepts disclosed in this specification are not limited by the drawings and should be interpreted to include all modifications, equivalents, and substitutions encompassed within the spirit and scope of the invention.

[0036] Terms containing ordinal numbers, such as "first" and "second," can be used to describe various constituent elements, but these constituent elements should not be limited to these terms. The terms can only be used to distinguish one constituent element from another.

[0037] When referring to any constituent element as being "connected" or "linked" to another constituent element, it should be understood that it can be directly connected or linked to another constituent element, or that another constituent element may be present in between. Conversely, it should be understood that if a constituent element is described as being "directly connected" or "directly linked" to another constituent element, there are no other constituent elements present in between.

[0038] Unless the context clearly specifies otherwise, the singular expression includes the plural expression.

[0039] It should be understood that in this application, terms such as "comprising" or "having" are used only to describe the presence of features, figures, steps, actions, constituent elements, components or combinations thereof as described in the specification, and are not intended to preclude the possibility of the presence or addition of one or more other features or figures, steps, actions, constituent elements, components or combinations thereof.

[0040] On the other hand, the display device in this embodiment of the invention is, for example, an intelligent display device that adds computer support to the broadcast receiving function. It faithfully retains the broadcast receiving function while also adding internet functionality, and can have more user-friendly interfaces such as a handwriting input device, a touchscreen, or a spatial remote control. Furthermore, with support for wired or wireless internet functionality, it can access the internet and computers, and can perform functions such as email, web browsing, online banking, and games. For such various functions, a standardized general-purpose operating system (OS) can be used.

[0041] Therefore, the display device described in this invention can freely add or remove various applications on a general operating system (OS) kernel, thus enabling it to perform various user-friendly functions. Specifically, the display device may be, for example, a network television, hybrid broadcast broadband television (HBBTV), a smart television, a light-emitting diode television (LEDTV), an organic light-emitting diode television (OLEDTV), etc., and may also be applicable to smartphones, depending on the situation.

[0042] Figure 1 This is a block diagram illustrating the various components of the display device 100. The display device 100 may include a broadcast receiver 110, an external device interface 171, a network interface 172, a storage unit 140, a user interface 173, an input unit 130, a control unit 180, a display module 150, an audio output unit 160, and a power supply unit 190.

[0043] The broadcast receiver 110 may include a tuning unit 111 and a demodulation unit 112.

[0044] On the other hand, unlike the accompanying drawings, the display device 100 may also include only the external device interface 171 and the network interface 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 also exclude the broadcast receiving unit 110.

[0045] The tuning unit 111 can select a broadcast signal from the broadcast signals received via an antenna (not shown) or a cable (not shown) that corresponds to a channel selected by the user or all pre-stored channels. The tuning unit 111 can convert the selected broadcast signal into an intermediate frequency signal or a baseband image or voice signal.

[0046] For example, if the selected broadcast signal is a digital broadcast signal, the tuning unit 111 converts the digital broadcast signal into a digital intermediate frequency (DIF) signal; if it is an analog broadcast signal, the tuning unit 111 converts the analog broadcast signal into an analog baseband image or speech signal (CVBS / SIF). That is, the tuning unit 111 can process both digital and analog broadcast signals. The analog baseband image or speech signal (CVBS / SIF) output from the tuning unit 111 can be directly input to the control unit 180.

[0047] On the other hand, the tuning unit 111 can sequentially select broadcast signals from the broadcast signals received through the antenna (not shown) or cable (not shown) that correspond to the channel selected by the user or all channels pre-stored, and convert them into intermediate frequency signals or baseband image or voice signals.

[0048] On the other hand, the tuning unit 111 may be equipped with multiple tuners in order to receive broadcast signals from multiple channels. Alternatively, the tuning unit 111 may also be a single tuner that simultaneously receives broadcast signals from multiple channels.

[0049] The demodulation unit 112 can receive the digital intermediate frequency (DIF) signal converted in the tuning unit 111 and perform demodulation. The demodulation unit 112 can output a streaming signal (TS) after performing demodulation and channel decoding. At this time, the streaming signal can be a signal multiplexed from image signals, voice signals, or data signals.

[0050] The streaming signal output from the demodulation unit 112 can be input to the control unit 180. After performing demultiplexing, image / speech signal processing, etc., the control unit 180 can output an image through the display module 150 and output speech through the audio output unit 160.

[0051] The sensing unit 120 refers to a device that detects changes within the display device 100 or changes in the external environment. For example, it may include at least one of a proximity sensor, an illumination sensor, a touch sensor, an infrared 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.).

[0052] The control unit 180 can control the display device 100 to check its status based on the information collected by the sensor unit 120, and inform the user or adjust itself to maintain optimal status when a problem occurs.

[0053] Furthermore, based on the illuminance detected by the sensor unit, the content, image quality, and size of the image provided to the display module 150 are differentiated and controlled to provide the optimal viewing environment. With the advancement of smart TVs, the functions integrated into the display device have increased, and the number of sensor units 120 has also increased accordingly.

[0054] The input unit 130 may be located on one side of the main body of the display device 100. For example, the input unit 130 may include a touchpad, physical buttons, etc. The input unit 130 may receive various user commands related to the operation of the display device 100 and transmit control signals corresponding to the input commands to the control unit 180.

[0055] Recently, as the bezel size of display devices 100 has become smaller, there is an increasing number of display devices 100 that minimize the physical button-like input section 130 exposed on their exterior. Instead, minimized physical buttons can be provided on the back or side, and user input can be received via a touchpad or a user input interface section 173 described later using a remote control device 200.

[0056] The storage unit 140 may store programs for signal processing and control within the control unit 180, and may also store processed image, voice, or data signals. For example, the storage unit 140 may store application programs designed to perform various operations that can be processed by the control unit 180, and may selectively provide a portion of the stored application programs when requested by the control unit 180.

[0057] The programs stored in the storage unit 140 are not subject to any particular restriction as long as they can be executed by the control unit 180. The storage unit 140 can also perform functions for temporarily storing image, voice, or data signals received from external devices through the external device interface unit 171. The storage unit 140 can store information related to a specified broadcast channel through channel memory functions such as channel mapping.

[0058] Although shown Figure 1 In one embodiment, the storage unit 140 and the control unit 180 are provided separately, but the present invention is not limited thereto, and the control unit 180 may also include the storage unit 140.

[0059] The storage unit 140 may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) and non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

[0060] The display module 150 can convert image signals, data signals, OSD (On-Screen Display) signals, control signals processed in the control unit 180, or image signals, data signals, control signals, etc., received from the interface unit 171 to generate drive signals.

[0061] Additionally, the display module 150 may include a microLED module as described below, according to an embodiment of the present invention.

[0062] The display module 150 can be a flexible display, or a 3D display. The 3D display module 150 can be either glasses-free or glasses-based.

[0063] The display device 100 includes: a display module 150 occupying most of the front area; and a housing covering the back and sides of the display module 150 and encapsulating the display module 150.

[0064] Previously, LCDs, which were mainly used, relied on backlight units to receive light because they were not self-emissive. A backlight unit is a device that provides a light source and uniformly supplies light from that source to the liquid crystal located on the front. While thinner backlight units can be achieved by gradually thinning them, it is difficult to implement them with flexible materials. When a backlight unit is bent, it becomes difficult to supply uniform light to the liquid crystal, resulting in variations in screen brightness.

[0065] Conversely, in the case of LED (Light Emitting Diode) or OLED (Organic Light Emitting Diode), since the elements constituting the pixels each emit their own light, a backlight unit is not required, and bending can be achieved. Furthermore, because each element emits its own light, even if the positional relationship with adjacent elements changes, it will not affect its own brightness, thus enabling a bending display module 150.

[0066] OLED panels officially debuted in mid-2010 and are rapidly replacing LCDs in the small and medium-sized display market. As a display made using the self-emissive phenomenon of light emission when an electric current flows through a fluorescent organic compound, OLEDs have a faster screen response time than LCDs, resulting in almost no ghosting when displaying dynamic images.

[0067] Since OLEDs are light-emitting display products that use three phosphor organic compounds with self-emissive functions, namely red, green, and blue, and emit light by combining positively charged particles with electrons injected from the negative and positive electrodes within the organic material, they do not require backlighting that would reduce color performance.

[0068] The display module 150 may include a magnet, a first power supply unit, and a first signal module.

[0069] The display module 150 can refer to the side where the image will be displayed as the front or front side. The display module 150 can also refer to the side where the image cannot be viewed as the back or back side. Alternatively, the display module 150 can be a touchscreen, serving as both an output and input device.

[0070] The audio output unit 160 receives the input of the voice-processed signal from the control unit 180 and outputs it as voice.

[0071] The interface unit 170 serves as a pathway for various external devices connected to the display device 100. The interface unit may include not only wired methods for transmitting and receiving data via cables, but also wireless methods utilizing antennas.

[0072] The interface section 170 may include at least one of the following: a wired / wireless headphone 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 port, a video I / O port, and a headphone port.

[0073] As an example of a wireless method, it may include the aforementioned broadcast receiver 110, which may include not only broadcast signals, but also mobile communication signals, short-range communication signals, wireless Internet signals, etc.

[0074] The external device interface section 171 can send or receive data with connected external devices. For this purpose, the external device interface section 171 may include an A / V input / output section (not shown).

[0075] The external device interface unit 171 can be connected to external devices such as DVD (Digital Versatile Disk), Blu-ray, game console, camera, camcorder, computer (laptop), set-top box, etc. in a wired / wireless manner, and can also perform input / output operations with external devices.

[0076] In addition, the external device interface unit 171 can establish a communication network with various remote control devices 200, and receive control signals 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.

[0077] 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 a neighboring mobile terminal. In particular, the external device interface unit 171 can receive device information, running application information, application images, etc., from the mobile terminal in mirror mode.

[0078] The network interface unit 172 can provide an interface for connecting the display device 100 to a wired / wireless network, including the Internet. For example, the network interface unit 172 can receive content or data provided by the Internet or a content provider or network operator. Alternatively, the network interface unit 172 may include a communication module (not shown) for connecting to a wired / wireless network.

[0079] The external device interface section 171 and / or the network interface section 172 may include: communication modules for short-range communication such as Wi-Fi (Wireless Fidelity), Bluetooth (Bluetooth), Bluetooth Low Energy (BLE), Zigbee, and NFC (Near Field Communication); and communication modules 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).

[0080] The user input interface 173 can transmit user input signals to the control unit 180, or transmit signals from the control unit 180 to the user. For example, it can receive and transmit user input signals such as power on / off, channel selection, and screen settings from the remote control device 200, or transmit user input signals input from local keys (not shown) such as power button, channel button, volume button, and setting value to the control unit 180, or transmit user input signals input from a sensor (not shown) that senses user gestures to the control unit 180, or send signals from the control unit 180 to the sensor.

[0081] The control unit 180 may include at least one processor, which controls the overall operation of the display device 100. Here, the processor may be a general-purpose processor such as a CPU (central processing unit). Alternatively, the processor may be a dedicated device such as an ASIC or a processor based on other hardware.

[0082] The control unit 180 can demultiplex the streams input through the tuning unit 111, demodulation unit 112, external device interface unit 171, or network interface unit 172, or process the demultiplexed signals to generate and output signals for image or voice output.

[0083] The image signal processed by the control unit 180 can be input to the display module 150 to display an image corresponding to the image signal. Additionally, the image signal processed by the control unit 180 can also be input to an external output device via the external device interface unit 171.

[0084] The voice signal processed in the control unit 180 can be output as sound to the audio output unit 160. Additionally, the voice signal processed in the control unit 180 can be output to an external output device via the external device interface unit 171. Although not shown in FIG2, the control unit 180 may include a demultiplexing unit, an image processing unit, etc.

[0085] 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 tuning unit 111 to select a channel chosen by the user or a broadcast corresponding to a pre-stored channel.

[0086] Furthermore, the control unit 180 can control the display device 100 using user commands or internal programs input through the user input interface unit 173. On the other hand, the control unit 180 can control the display module 150 to display images. At this time, the image displayed on the display module 150 can be a static image or a dynamic image, and can be a 2D image or a 3D image.

[0087] On the other hand, the control unit 180 can display specified 2D objects within the image displayed by the display module 150. For example, the object can be at least one of the following: a linked webpage (newspaper, magazine, etc.), an EPG (Electronic Program Guide), various menus, widgets, icons, still images, animated images, and text.

[0088] On the other hand, the control unit 180 can use amplitude shift keying (ASK) to modulate and / or demodulate the signal. Here, amplitude shift keying (ASK) refers to a method of modulating the signal by setting the amplitude of the carrier wave differently according to the data value, or restoring the analog signal to digital data value according to the amplitude of the carrier wave.

[0089] For example, the control unit 180 can modulate the image signal using amplitude shift keying (ASK) and transmit it via a wireless communication module.

[0090] For example, the control unit 180 can demodulate and process the image signal received through the wireless communication module using amplitude shift keying (ASK).

[0091] Therefore, even without using unique identifiers such as MAC addresses (Media Access Control Addresses) or complex communication protocols such as Transmission Control Protocol / Internet Protocol (TCP / IP), the display device 100 can conveniently send and receive signals with other adjacent image display devices.

[0092] On the other hand, the display device 100 may also include a camera unit (not shown). The camera unit can capture images of the user. Although the camera unit can be implemented by a single camera, it is not limited to this and can also be implemented by multiple cameras. On the other hand, the camera unit can be embedded in the upper part of the display module 150 of the display device 100 or configured separately. The image information captured by the camera unit can be input to the control unit 180.

[0093] The control unit 180 can identify the user's position based on the image captured by the camera unit. 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 and y-axis coordinates within the display module 150 corresponding to the user's position.

[0094] The control unit 180 can detect the user's gestures based on each or a combination of images captured by the camera unit or signals detected by the sensor unit.

[0095] The power supply unit 190 can supply power to the entire display device 100. In particular, it can supply power to the control unit 180, the display module 150 for image display, the audio output unit 160 for audio output, etc., which are implemented in the form of a system on chip (SOC).

[0096] Specifically, the power supply unit 190 may include: a converter (not shown) that converts AC power to DC power; and a DC / DC converter (not shown) that converts the level of the DC power.

[0097] On the other hand, the power supply unit 190 functions to receive power from an external source and distribute power to various components. The power supply unit 190 can supply AC power by directly connecting to an external power source, and in addition to batteries, it can also include a rechargeable form of the power supply unit 190.

[0098] In the former case, it is used by connecting a wired cable, which makes it difficult to move and limits its range of movement. In the latter case, although it allows for free movement, it increases the weight by a factor of the battery and the size becomes larger. In order to charge, it needs to be directly connected to the power cable for a specified time, or combined with the charging unit (not shown) that supplies power.

[0099] The charging unit can be connected to the display device via exposed terminals, or it can wirelessly charge the built-in battery when it is nearby.

[0100] The remote control device 200 can transmit user input to the user input interface 173. For this purpose, the remote control device 200 can use Bluetooth, radio frequency (RF) communication, infrared (IR) communication, UWB (Ultra-wideband), ZigBee, etc. Furthermore, the remote control device 200 can receive image, voice, and data signals output from the user input interface 173 and display them on the remote control device 200 or output them via voice.

[0101] On the other hand, the aforementioned display device 100 can be a digital broadcast receiver capable of receiving fixed or mobile digital broadcasts.

[0102] on the other hand, Figure 1 The block diagram of the display device 100 shown is only a block diagram of one embodiment of the present invention. The various components of the block diagram can be integrated, added or omitted according to the actual specifications of the display device 100 to be implemented.

[0103] That is, two or more constituent elements can be integrated into one constituent element, or one constituent element can be split into two or more constituent elements, as needed. Furthermore, the functions performed in each box are for illustrating embodiments of the present invention, and their specific operations or apparatus do not limit the scope of the present invention.

[0104] Figure 2 This is an exploded view of a display device 100 according to an embodiment of the present invention. Figure 3 This is a diagram showing a display device 100 according to an embodiment of the present invention, viewed from the rear. Figure 4 This is a cross-sectional view used to compare and illustrate a conventional display device 100 with a display device 100 according to an embodiment of the present invention. Figure 5 This is a diagram showing the pattern printed on the back side of the optical substrate 211 in a display device 100 according to an embodiment of the present invention. Additionally, Figure 6 This is a cross-sectional view showing another embodiment of the display device 100 of the present invention.

[0105] Hereinafter, when describing a display device 100 according to an embodiment of the present invention, the x-axis direction is defined as the direction towards the front and rear, the y-axis direction is defined as the left and right direction, and the z-axis direction is defined as the up and down direction.

[0106] A display device 100 according to an embodiment of the present invention may include a display panel 210, a cover plate 220, a support panel 230, and a rear cover 240. Here, as Figure 4 As shown, the display panel 210 for outputting images may include an optical substrate 211 on which a TFT array layer 212 is mounted. That is, the optical substrate 211 may constitute the back side of the display panel 210. Here, the optical substrate 211 may be formed of a metal material. In addition, OLEDs (Organic Light Emitting Diodes) may be formed on the TFT array layer 212.

[0107] Furthermore, in a display device 100 according to an embodiment of the present invention, such as Figure 4 As shown, the display panel 210 may include glass 213 mounted on the TFT array layer 212, and may include a front cover 214 located on the front side of the glass 213.

[0108] The cover plate 220 can cover the back periphery of the optical substrate 211. For example... Figure 2 As shown, the cover plate 220 can also cover a portion of the back periphery of the optical substrate 211, and in order to cover the entire back periphery, it can also be formed in the shape of a rim.

[0109] The support panel 230 can be located on the lower back side of the optical substrate 211. Additionally, a printed circuit board that provides drive signals to the display panel 210 can be mounted thereon. The rear cover 240 can cover the support panel 230 and is located on the lower back side of the optical substrate 211.

[0110] Therefore, as Figure 3 As shown, in one embodiment of the present invention, the display device 100 may expose the upper side of the optical substrate 211 that constitutes the back side of the display panel 210. More details will be described later.

Figure 4 (a) is in existing display devices, with Figure 3 The sectional view corresponding to the AA direction. Figure 4 (b) is in a display device 100 according to an embodiment of the present invention, Figure 3 AA sectional view.

[0112] exist Figure 4In the case of the conventional display device shown in (a), it includes: an optical substrate 11 forming the back side of the display panel 10; a cover plate 20 covering the sides and the periphery of the back side of the display panel 10; and a rear cover 30 combined with the cover plate 20 and covering the entire back side of the display panel 10. In addition, the cover plate 20 is bonded to the back side of the optical substrate 11 by an adhesive member 40.

[0113] However, as mentioned above, the trend towards larger displays has created a demand for solutions that can reduce the weight and thickness of the display device 100 and lower manufacturing costs. Furthermore, the importance of the display device 100's appearance design to meet customer requirements is becoming increasingly apparent.

[0114] Therefore, as Figure 3 and Figure 4 As shown in (b), a display device 100 according to an embodiment of the present invention can reduce the weight of the display device 100, reduce the thickness of the device, and reduce manufacturing costs by changing the structure and shape of the cover plate 220 and the rear cover 240 located on the back of the display panel 210. In addition, the appearance design can be diversified by exposing the optical substrate 211 constituting the back of the display panel 210.

[0115] In one embodiment of the present invention, the display device 100 may be coated with an adhesive member 250 such as optically transparent adhesive (OCA), which is used to bond and combine the two members between the front side of the cover plate 220 and the back side of the optical substrate 211.

[0116] Here, in order to minimize the exposure of the adhesive member 250 coated between the front side of the cover plate 220 and the back side of the optical substrate 211, the cover plate 220 may include a step 221, which is formed by protruding from one end of the front side toward the back side of the optical substrate 211. Furthermore, the adhesive member 250 can be shielded by the step 221 of the cover plate 220. Therefore, by forming the step 221 in the cover plate 220, even if the shape of the rear cover 240 is changed, the exposure of the adhesive member 250 can be minimized.

[0117] Furthermore, in a display device 100 according to an embodiment of the present invention, the step 221 of the cover plate 220 can be separated from the back side of the optical substrate 211 to form a gap. This is a means to prevent damage that the cover plate 220, which may be exposed to the outside due to the shape change of the rear cover 240, may cause to the periphery of the back side of the optical substrate 211.

[0118] Furthermore, by separating the step 221 of the cover plate 220 from the back surface of the optical substrate 211 to form a gap, damage to the periphery of the back surface of the optical substrate 211 that may occur when the cover plate 220 and the back surface of the optical substrate 211 are bonded together by the adhesive member 250 can be minimized. Therefore, as an embodiment of the present invention, the gap between the step 221 of the cover plate 220 and the back surface of the optical substrate 211 can be formed by an interval of about 0.2 mm and separated.

[0119] Furthermore, in a display device 100 according to an embodiment of the present invention, the cover plate 220 may include a side portion 222, which is formed to cover the side periphery of the display panel 210. Additionally, as described above, since the cover plate 220 is a component that forms the appearance of the display device 100 of the present invention, it may include an inclined surface 223 formed as a design element, tilted towards the rear side.

[0120] Furthermore, in one embodiment of the present invention, the display device 100 exposes the optical substrate 211 by changing the structure and shape of the cover plate 220 and the rear cover 240 located on the back of the display panel 210, thereby making the heat dissipation structure of the display panel 210 more favorable.

[0121] Relatedly, in Figure 4 In the case of the existing display device shown in (a), the back cover 30 is in direct contact with the back of the metal optical substrate 11 and dissipates heat to the outside through thermal conduction. Conversely, as... Figure 4 As shown in (b), a display device 100 of an embodiment of the present invention is able to dissipate heat in a convection manner through an optical substrate 211 exposed to the outside.

[0122] Also refer to Figure 2 In one embodiment of the present invention, the display device 100 may further include a heat sink 280, which is located between the back side of the optical substrate 211 and the printed circuit board mounted on the support panel 230. That is, by adding a heat sink 280 to the lower part of the optical substrate 211 that is not exposed to the outside, the display device 100 of the present invention can improve the heat dissipation structure of the display panel 210.

[0123] Figure 5 This diagram illustrates the pattern printed on the back side of the optical substrate 211 in a display device 100 according to an embodiment of the present invention. Figure 5 (a) and (b) are diagrams illustrating various embodiments of the pattern texture.

[0124] In a display device 100 according to an embodiment of the present invention, the optical substrate 211 may include a pattern printed on its back side, as shown in reference to... Figure 3The pattern printed on the back of the optical substrate 211 can be exposed to the outside between the cover plate 220 and the back cover 240.

[0125] Therefore, the display device 100 of the present invention can meet the customer's requirements for appearance design by exposing various patterns and textures printed on the back of the optical substrate 211 exposed on the surface.

[0126] Figure 6 This is a cross-sectional view showing another embodiment of the display device 100 of the present invention. (See also...) Figure 4 (b) can be configured with a different shape for the cover plate 220 covering the back periphery of the optical substrate 211. That is, by further forming at least one hole 224 in the cover plate 220, the cover plate 220 can be made lighter. As a result, the weight of the display device 100 can be reduced, and the thickness and manufacturing cost can be reduced compared to existing devices.

[0127] Figure 7 This diagram shows a reinforcing member 260 attached to the back of a cover plate 220 in a display device 100 according to an embodiment of the present invention. Additionally, Figure 8 This is a diagram showing a support rod 270 for fixing a support panel 230 in a display device 100 according to an embodiment of the present invention.

[0128] As described above, since the cover plate 220 covering the back periphery of the optical substrate 211 constitutes the appearance of the display device 100 of the present invention, in order to ensure rigidity, the display device 100 of one embodiment of the present invention may further include reinforcing members 260 attached to the two corners of the upper back side of the cover plate 220. Furthermore, the reinforcing members 260 can prevent damage to the optical substrate 211 constituting the back side of the display panel 210 and the cover plate 220 covering the back periphery of the optical substrate 211 caused by external impacts or the like.

[0129] Also refer to Figure 2 and Figure 8 In one embodiment of the present invention, the display device 100 may further include a support rod 270, which is coupled to a cover plate 220 and fixes a support panel 230. The support panel 230 is coupled to the cover plate 220 via a mating surface formed by extending from the bottom in a left-right direction. Furthermore, the support rod 270 is coupled to the back of the support panel 230, and both ends of the support rod 270 are coupled to the cover plate 220, thereby stably fixing the cover plate 220 and the support panel 230.

[0130] In summary, the display device of the present invention, by exposing the optical substrate on which the TFT array layer constituting the back of the display panel is mounted, enables diverse heat dissipation and appearance design. Furthermore, the weight and thickness of the display device can be reduced and manufacturing costs lowered by changing the structure and shape of the cover located on the back of the display panel. Additionally, by printing and exposing various patterns and textures on the back of the optical substrate, the customer's requirements regarding appearance design can be met.

[0131] The detailed description described above should not be construed as restrictive in all respects, but rather as exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention fall within its scope.
