Technical Field
[0001] This invention relates to a display device and a method for controlling the display device. Background Technology
[0002] Display devices can provide images to users using a display panel. In the case of a curved TV, the display can provide images to the user through a display panel that is concave and curved to maintain a constant distance from the user's eyes to the center and sides of the screen. In this case, the three-dimensionality of the image can be increased. Therefore, the user's immersion in the image can be enhanced, and eye strain can be reduced.
[0003] However, curved TVs may take up a lot of space, and users may experience image distortion depending on their viewing position. Furthermore, when multiple users are watching a curved TV, those at the center of the curvature may perceive image distortion. Summary of the Invention

[0065] Figure 1 This is a block diagram illustrating the configuration of a display device 1 according to an embodiment of the present invention. The display device 1 may include a display unit 1100, an image processor 1200, an image capture unit 1300, a user input unit 1400, a storage unit 1500, a communicator 1600, and a controller 1700.
[0066] Display unit 1100 can display images. In one embodiment, display unit 1100 can display images based on image signals processed by image processor 1200. In one embodiment, display unit 1100 can display digital images. Display unit 1100 may include display panel 10 and frame assembly 20. Display panel 10 can display images. Frame assembly 20 can bend display panel 10. Therefore, display panel 10 can be bent into various shapes.
[0067] In one embodiment, the display unit 1100 can display communication interface information provided by the communicator 1600. The controller 1700 can control the display unit 1100 so that the display panel 10 displays the communication interface information stored in the storage unit 1500.
[0068] The image processor 1200 can process image signals received from an external source. The image processor 1200 can perform various preset image processing procedures on the image signals. The image processor 1200 can output the image signal that has undergone these procedures to the display unit 1100, thereby displaying an image on the display panel 10.
[0069] The image processor 1200 may include an image receiver (not shown) that receives image signals from an external source. The image receiver may be implemented in various ways, corresponding to the specifications of the received image signal and the implementation of the display device 1. For example, the image processor 1200 may wirelessly receive RF (Radio Frequency) signals transmitted from a broadcast station (not shown), or wiredly receive composite video, component video, super video, SCART-based, HDMI (High Definition Multimedia Interface), and other image signals. In the case where the image signal is a broadcast signal, the image processor 1200 may include a tuner that adjusts the broadcast signal by channel.
[0070] In other embodiments, the image signal can be input from an external device. For example, the image signal can be input from an external device such as a PC, AV equipment, smartphone, or smart tablet. In yet another embodiment, the image signal can be a signal written from data received via a network such as the Internet. In this case, the display device 1 can perform network communication via the communicator 1600. In yet another embodiment, the image signal can be a signal written from data stored in a non-volatile storage unit 1500 such as flash memory or a hard disk. The storage unit 1500 can be disposed inside or outside the display device 1; when disposed externally, it may also include a connection portion (not shown) connected to the storage unit 1500.
[0071] There is no limitation on the types of image processing procedures performed by the image processor 1200. For example, it may include at least one of decoding, de-interlacing, frame refresh rate transformation, scaling, noise reduction for improving image quality, detail enhancement, and line scanning, corresponding to various image formats. The image processor 1200 may be implemented as a combination of individual components capable of performing these procedures independently, or as a System-on-Chip (SoC) integrating various functions.
[0072] The image capture device 1300 can capture images of the external environment to obtain external images. The image capture device 1300 can be an image capture unit. In one embodiment, the image capture device 1300 can be implemented as a camera for capturing images of the external environment. In this case, the camera can be positioned at a predetermined location on the display device 1. For example, the camera can be positioned on the upper part of the display device 1 or inside the display unit 1100. The camera's position is not limited, and it can also be separated from the main body of the display device 1 and positioned externally, depending on the situation.
[0073] Image capture device 1300 may include a lens (not shown) through which an image is transmitted and an image sensor 1310 that senses the image transmitted through the lens. Image sensor 1310 may be implemented as a CCD image sensor or a CMOS image sensor. The image input through image capture device 1300 may be processed in image processor 1200.
[0074] The user input unit 1400 can receive user input. Through user operation and input, the user input unit 1400 can transmit various preset control commands or unrestricted information to the controller 1700.
[0075] In one embodiment, the user input unit 1400 can be disposed within the main body of the display device 1, or it can be separated from the display device 1 to receive input signals from an input device. For example, the user input unit 1400 can receive input signals via a keypad (or input panel) (not shown) including numeric keys, menu keys, and other buttons disposed within the main body of the display device 1. Alternatively, the user input unit 1400 can receive input signals by generating pre-set commands / data / information / signals in a manner capable of remotely controlling the display device 1 and transmitting them to a separate input device such as a remote controller, keyboard, or mouse. In this case, the separate input device can be an external device connected to the main body of the display device 1 and capable of wireless communication, including infrared communication, RF communication, wireless LAN communication, etc. The input device can be operated by the user to transmit pre-set commands to the display device 1. Alternatively, the user input unit 1400 can receive the user's voice signal.
[0076] Storage unit 1500 can store various types of data. Storage unit 1500 can store unlimited data according to the control of controller 1700. Storage unit 1500 may include at least one of volatile memory and non-volatile memory. Volatile memory may include DRAM (Dynamic Random Access Memory), SRAM (Static RAM), etc., and non-volatile memory may include ROM (Read Only Memory), PROM (Programmable ROM), EPROM (Electrically Programmable ROM), EEPROM (Electrically Erasable and Programmable ROM), flash memory, PRAM (Phase-change RAM), MRAM (Magnetic RAM), RRAM (Resistive RAM), FRAM (Ferroelectric RAM), hard disk drive (HDD), and solid-state drive (SSD), etc.
[0077] The storage unit 1500 can be accessed by the controller 1700, and data reading, recording, correction, deletion, and updating can be performed. The data stored in the storage unit 1500 may include operating system data for driving the display device 1, various applications that can be executed on the operating system, image data, and additional data.
[0078] The storage unit 1500 can store input / output signals or data corresponding to the operation of each component, as controlled by the controller 1700. The storage unit 1500 can store control programs used for controlling the display device 1, GUIs (graphical user interfaces) related to applications provided by the manufacturer or downloaded from external sources, images used to provide the GUI, user information, documents, databases, or associated data.
[0079] The communicator 1600 can perform wired and / or wireless communication with external devices. In one embodiment, the communicator 1600 can provide at least one of the following communication interfaces: Wi-Fi, Bluetooth, RF (Radio Frequency), Zigbee, Wireless LAN, Infrared communication, UWB (Ultra Wideband), and NFC (Near Field Communication).
[0080] The communicator 1600 can be built into the main body of the display device 1. In other embodiments, it can be implemented as a dongle or module and can be detached from the connector (not shown) of the display device 1.
[0081] The controller 1700 can control the display device 1. The controller 1700 can control the overall operation of the display device 1 and the signal flow between its internal components. The controller 1700 can perform data processing functions. The controller 1700 can control the power supply from the power supply unit (not shown) to the internal components. In one embodiment, when there is user input or when preset and stored conditions are met, the controller 1700 can execute the OS (Operation System) and various application programs stored in the storage unit 1500.
[0082] The controller 1700 may obtain information to bend the display panel 10 and, taking into account the obtained information, control the display panel 10 to bend and display an image. In one embodiment, the controller 1700 may control the housing assembly 20 to bend the display panel 10.
[0083] Figure 2a This is a perspective view schematically illustrating a display device 1 according to an embodiment of the present invention. Figure 2b and Figure 2c This is a perspective view schematically illustrating a display device 1 according to various embodiments of the present invention.
[0084] Figure 2a This is a perspective view showing the front surface of the display unit 1100. Figure 2b and Figure 2c This is a perspective view of the back of the display unit 1100.
[0085] Reference Figure 2a The display device 1 may include a display unit 1100 and a controller 1700. The display unit 1100 may include a display panel 10.
[0086] The display panel 10 may include edge positions. The display panel 10 may include a first edge position EG1 and a second edge position EG2. The first edge position EG1 and the second edge position EG2 may be the ends of the display panel 10. In one embodiment, the first edge position EG1 and the second edge position EG2 may meet each other. In this case, the first edge position EG1 and the second edge position EG2 may intersect each other. Alternatively, the first edge position EG1 and the second edge position EG2 may meet each other in a curved shape.
[0087] The first edge position EG1 can extend in a first direction. The second edge position EG2 can extend in a second direction. In this case, the first and second directions can intersect each other. For example, the first and second directions can form an acute angle, a right angle, or an obtuse angle with each other. Hereinafter, a detailed explanation will focus on the case where the first direction is the x-direction or -x-direction and the second direction is the y-direction or -y-direction.
[0088] The display panel 10 can be bent. In one embodiment, the display panel 10 can be bent from a first direction (e.g., the x-direction or the -x-direction) toward a third direction. The third direction can be an acute angle, a right angle, or an obtuse angle with the first direction (e.g., the x-direction or the -x-direction) and the second direction (e.g., the y-direction or the -y-direction), respectively. In one embodiment, the third direction can be the z-direction or the -z-direction. Bending the display panel 10 from the first direction (e.g., the x-direction or the -x-direction) toward the third direction (e.g., the z-direction or the -z-direction) means that the cross-section of the display panel 10 intersecting a plane (e.g., the xz plane) extending in the first direction (e.g., the x-direction or the -x-direction) and the third direction (e.g., the z-direction or the -z-direction) is bent concavely or convexly.
[0089] In other embodiments, the display panel 10 may be bent from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). Bending the display panel 10 from the second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction) means that the cross-section of the display panel 10 intersecting a plane (e.g., the yz plane) extending in both the second direction (e.g., the y-direction or -y-direction) and the third direction (e.g., the z-direction or -z-direction) is bent concavely or convexly.
[0090] In another embodiment, the display panel 10 can be bent from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction) and from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). In this case, the display panel 10 can be stretched and / or contracted in the first direction (e.g., the x-direction or -x-direction) and / or the second direction (e.g., the y-direction or -y-direction). If the display panel 10 cannot be stretched and / or contracted in the first direction (e.g., the x-direction or -x-direction) and / or the second direction (e.g., the y-direction or -y-direction), relatively large stresses may be generated at the corners of the display panel 10, potentially damaging it.
[0091] The display panel 10 in embodiments of the present invention can be a stretchable display panel capable of being stretched and / or contracted in a first direction (e.g., the x-direction or the -x-direction) and / or a second direction (e.g., the y-direction or the -y-direction). Therefore, even if the display panel 10 is bent in various directions, the stress acting on the display panel 10 can be relatively small, which can prevent or reduce damage to the display panel 10.
[0092] Display panel 10 may include a display area DA. Display area DA may display an image. In one embodiment, display panel 10 may be controlled by controller 1700 to display an image in display area DA.
[0093] Pixels can be configured in the display area DA. In one embodiment, multiple pixels can be configured in the display area DA. The display panel 10 can provide an image using light emitted from the pixels. In one embodiment, the pixels may include display elements.
[0094] In one embodiment, the display panel 10 may include a component area CPA. The component area CPA may be an area configured with components capable of imparting various functions to the display device 1. In one embodiment, the components may include an image capture device (IMAGE ACQUIRER), such as a light sensor or a camera. The component area CPA may include a transmission area that allows light from the sensor or light traveling toward the camera to pass through.
[0095] The component region CPA can be at least partially surrounded by the display region DA. For example, the component region CPA can be entirely surrounded by the display region DA. As another example, the component region CPA can be only partially surrounded by the display region DA.
[0096] In one embodiment, multiple component regions CPAs may be provided. In one embodiment, the multiple component regions CPAs may be spaced apart from each other in a first direction (e.g., the x-direction or the -x-direction) and / or a second direction (e.g., the y-direction or the -y-direction).
[0097] The component area CPA can be configured to be offset from the center of the display panel 10 in a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction).
[0098] In one embodiment, the component region CPA may be circular or elliptical in a plane (e.g., the xy plane). In other embodiments, the component region CPA may be various shapes such as quadrilaterals in a plane. In yet another embodiment, the component region CPA may include a curved shape.
[0099] The component (not shown) may overlap with the component area CPA. In this case, the component may be disposed inside the display unit 1100. The component may be an electronic element that utilizes light or sound. For example, the electronic element may include a sensor that receives and utilizes light, such as an infrared sensor; a camera that receives light to capture an image; a sensor that outputs light or sound and senses it to measure distance or identify fingerprints; a small lamp that outputs light; or a speaker that outputs sound. In the case of an electronic element that utilizes light, light of various wavelengths, such as visible light, infrared light, and ultraviolet light, may be used.

[0102] Reference Figure 2b and Figure 2c The display unit 1100 may include a display panel 10 and a housing assembly 20. The housing assembly 20 can bend the display panel 10. The housing assembly 20 may be configured behind the display panel 10. The housing assembly 20 may be configured on the opposite side of the display area DA.
[0103] The housing assembly 20 allows the display panel 10 to bend from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction) intersecting the first direction (e.g., the x-direction or -x-direction) and the second direction (e.g., the y-direction or -y-direction). The first edge position EG1 of the bent display panel 10 may have curvature.

[0104] The housing assembly 20 can bend the display panel 10 from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). In this case, the second edge position EG2 of the bent display panel 10 can have curvature. The second edge position EG2 of the bent display panel 10 can bend from the second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction).
[0105] The housing assembly 20 can bend the display panel 10 from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction), and can bend the display panel 10 from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). The first edge position EG1 and the second edge position EG2 of the bent display panel 10 can each have curvature.
[0106] The housing assembly 20 can be controlled by the controller 1700. The housing assembly 20 can be controlled by the controller 1700 to bend from a first direction (e.g., the x-direction or -x-direction) towards a third direction (e.g., the z-direction or -z-direction). The housing assembly 20 can be controlled by the controller 1700 to bend from a second direction (e.g., the y-direction or -y-direction) towards a third direction (e.g., the z-direction or -z-direction). The housing assembly 20 may include a first housing 21, a second housing 23, and a plurality of support members 25.
[0107] The first housing 21 may extend in a first direction (e.g., the x-direction or the -x-direction). The first housing 21 may be configured behind the display panel 10. Figure 2b The illustration shows a case where a first housing 21 is disposed behind the display panel 10, but in other embodiments, multiple first housings 21 may be provided behind the display panel 10.
[0108] In one embodiment, the first housing 21 may comprise austenitic stainless steel. In other embodiments, the first housing 21 may be made of stainless steel, invar, nickel, cobalt, nickel alloys, nickel-cobalt alloys, etc. In yet another embodiment, the first housing 21 may be made of various metallic materials. In still another embodiment, the first housing 21 may comprise a polymer compound (e.g., a polymer).
[0109] The first housing 21 can be bent from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction). The first housing 21 can be bent under the control of the controller 1700. Therefore, the first housing 21 can cause the display panel 10 to bend from the first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction). Furthermore, the first housing 21 can be bent such that the first edge position EG1 of the display panel 10 has a curvature.
[0110] In one embodiment, the first housing 21 may be integrally formed in a first direction (e.g., the x-direction or the -x-direction). In other embodiments, the first housing 21 may include a plurality of separate first housing portions, with a second housing 23 sandwiched between the plurality of first housing portions.
[0111] The second housing 23 may extend in a second direction (e.g., the y-direction or the -y-direction). The second housing 23 may be disposed behind the display panel 10. In one embodiment, multiple second housings 23 may be provided behind the display panel 10. In other embodiments, a single second housing 23 may be disposed behind the display panel 10.
[0112] In one embodiment, the second housing 23 may comprise austenitic stainless steel.

[0113] The second housing 23 can be bent from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). The second housing 23 can be bent under the control of the controller 1700. Therefore, the second housing 23 can cause the display panel 10 to bend from the second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). Furthermore, the second housing 23 can be bent such that the second edge position EG2 of the display panel 10 has a curvature.
[0114] In one embodiment, the second housing 23 may be integrally provided in a second direction (e.g., the y-direction or the -y-direction). In other embodiments, the second housing 23 may include a plurality of separable second housing portions, with the first housing 21 sandwiched between the plurality of second housing portions.
[0115] The first housing 21 and the second housing 23 can be connected to each other. (Refer to...) Figure 2b It can be composed of a first housing 21 and a second housing 23 as a single unit. (Refer to...) Figure 2c The first housing 21 and the second housing 23 can be separate housings. In one embodiment, the second housing 23 can be disposed between the first housing 21 and the display panel 10.
[0116] In one embodiment, a wire 27 may be disposed inside the first housing 21 and / or the second housing 23. The wire 27 can cause the first housing 21 and / or the second housing 23 to bend. For example, the first housing 21 and / or the second housing 23 can be bent by shrinking the wire 27 or by shortening the length of the wire 27 by means of a motor.
[0117] Multiple support members 25 can support the display panel 10. In one embodiment, the multiple support members 25 can be disposed between the display panel 10 and the first housing 21. The multiple support members 25 can be fixed to the first housing 21. In one embodiment, the multiple support members 25 can be disposed between the display panel 10 and the second housing 23. The multiple support members 25 can be fixed to the second housing 23.
[0118] Multiple support members 25 can maintain the shape of the display panel 10. In one embodiment, the display panel 10 can be a stretchable display panel. In this case, the shape of the display panel 10 can be changed in various ways. That is, the display panel 10 can be flexible. The multiple support members 25 support the display panel 10, thus maintaining the shape of the display panel 10.
[0119] In one embodiment, a plurality of support members 25 may extend in a first direction (e.g., the x-direction or the -x-direction). In this case, the plurality of support members 25 may be spaced apart from each other along a second direction (e.g., the y-direction or the -y-direction). In other embodiments, a plurality of support members 25 may extend in a second direction (e.g., the y-direction or the -y-direction). In this case, the plurality of support members 25 may be spaced apart from each other along a first direction (e.g., the x-direction or the -x-direction). The following detailed description focuses on the case where the plurality of support members 25 extend in a first direction (e.g., the x-direction or the -x-direction).
[0120] In one embodiment, the support member 25 may comprise austenitic stainless steel. In other embodiments, the support member 25 may be manufactured from stainless steel, invar, nickel, cobalt, nickel alloys, nickel-cobalt alloys, etc. In yet another embodiment, the support member 25 may be manufactured from various metallic materials. In still another embodiment, the support member 25 may comprise a polymer compound (e.g., a polymer).
[0121] Multiple support members 25 can be bent from a first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction). In one embodiment, the first housing 21 can be bent from the first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction). For example, when the first housing 21 is bent from the first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction), the multiple support members 25 can also be bent from the first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction). Therefore, the display panel 10 can be bent from the first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction).
[0122] At least one of the plurality of support members 25 is movable in a third direction (e.g., the z-direction or the -z-direction). For example, the support member 25 adjacent to the first edge position EG1 is movable in a third direction (e.g., the z-direction or the -z-direction). In one embodiment, the second housing 23 can move at least one of the plurality of support members 25 in a third direction (e.g., the z-direction or the -z-direction). For example, when the second housing 23 is bent from a second direction (e.g., the y-direction or the -y-direction) toward a third direction (e.g., the z-direction or the -z-direction), at least one of the plurality of support members 25 can move in a third direction (e.g., the z-direction or the -z-direction). Therefore, the display panel 10 can be bent from the second direction (e.g., the y-direction or the -y-direction) toward a third direction (e.g., the z-direction or the -z-direction).
[0123] The controller 1700 can obtain information to bend the display panel 10 and bend the display panel 10 in consideration of the obtained information. The controller 1700 may include a first drive unit 1710 and a second drive unit 1730.
[0124] The first drive unit 1710 can control the housing assembly 20. In one embodiment, the first drive unit 1710 can control the bending of the first housing 21 and / or the second housing 23. In one embodiment, the first drive unit 1710 may include a motor. The motor can cause the wire 27 to contract or wind around to reduce the length of the wire 27.
[0125] In one embodiment, the first drive unit 1710 may include multiple motors. The multiple motors can control the bending of the first housing 21 and the second housing 23, respectively. In one embodiment, the multiple motors can control the bending of one housing. For example, when multiple motors control the first housing 21, the bending of both ends of the first housing 21 can be adjusted independently. As another example, when multiple motors control the second housing 23, the bending of both ends of the second housing 23 can be controlled independently. Therefore, the display panel 10 can be bent in various shapes.
[0126] In one embodiment, the first drive unit 1710 may be configured behind the display unit 1100. In this case, the first drive unit 1710 may include a fixing member for fixing the display unit 1100 to an external wall or the like. For example, the fixing member may include a bracket.
[0127] The second drive unit 1730 can be controlled to rotate the display unit 1100 about a second direction (e.g., the y-direction or the -y-direction). In one embodiment, the second drive unit 1730 may include a motor. The motor can rotate the display unit 1100 about a second direction (e.g., the y-direction or the -y-direction). Therefore, the display panel 10 can be rotated about a second direction (e.g., the y-direction or the -y-direction) by the controller 1700.
[0128] Figure 3 It is a schematic representation along Figure 2a A cross-sectional view of the AA′ line display section 1100. Figure 3 In, with Figure 2a and Figure 2b The same symbol represents the same component, so repeated descriptions are omitted.
[0129] Reference Figure 3 The display unit 1100 may include a display panel 10, a cover window CW, an adhesive layer AL, a padding layer CSL, and multiple support members 25.
[0130] A cover window CW can be configured on the display panel 10. The cover window CW can be a flexible window. The cover window CW can be easily bent by external force without causing cracks, etc., while protecting the display panel 10. In one embodiment, the cover window CW can be a stretchable cover window that can be stretched and / or retracted.

[0132] An adhesive layer AL can be disposed between the display panel 10 and the cover window CW. The adhesive layer AL can attach the display panel 10 and the cover window CW to each other. In one embodiment, the adhesive layer AL may include an optically clear adhesive (OCA).
[0133] A cushioning layer CSL can be configured between the display panel 10 and the plurality of support members 25. The cushioning layer CSL can act as a buffer between the display panel 10 and the plurality of support members 25. For example, the plurality of support members 25 can move independently in a third direction (e.g., the z-direction or the -z-direction). The distances that the plurality of support members 25 move in the third direction (e.g., the z-direction or the -z-direction) can be different. In this case, the position of the cushioning layer CSL can be continuously changed according to the discontinuous movement distances of the plurality of support members 25. Therefore, the position of the display panel 10 can be continuously changed by the cushioning layer CSL and the plurality of support members 25, and it can be bent. In addition, the cushioning layer CSL can prevent or reduce damage to the display panel 10 caused by the plurality of support members 25.
[0134] In one embodiment, the cushioning layer CSL may include an elastomer. For example, it may include vulcanized natural rubber, synthetic rubber, elastic fibers, foam, or thermoplastic elastomer. As other examples, the cushioning layer CSL may include at least one of polyolefin, polyvinyl chloride, elastomeric silicone, elastomeric polyurethane, and elastomeric polyisoprene. In some embodiments, a first lower adhesive layer may be disposed between the cushioning layer CSL and the display panel 10. In some embodiments, a second lower adhesive layer may be disposed between the cushioning layer CSL and the plurality of support members 25. For example, at least one of the first and second lower adhesive layers may be a pressure-sensitive adhesive (PSA).

[0136] Reference Figure 4 The display panel 10 may include edge positions. In one embodiment, the display panel 10 may include a first edge position EG1 extending in a first direction (e.g., the x-direction or the -x-direction) and a second edge position EG2 extending in a second direction (e.g., the y-direction or the -y-direction). The first edge position EG1 and the second edge position EG2 may be the ends of the display panel 10. In one embodiment, the first edge position EG1 and the second edge position EG2 may meet each other.
[0137] Display panel 10 may be an organic light-emitting display panel that utilizes organic light-emitting diodes (OLEDs) including an organic light-emitting layer as a display element. Alternatively, display panel 10 may be a light-emitting diode (LED) display panel that utilizes light-emitting diodes (LEDs) as a display element. The size of the LED may be on the micrometer or nanometer scale. For example, the LED may be a micrometer LED. Alternatively, the LED may be a nanorod LED. The nanorod LED may include gallium nitride (GaN). In one embodiment, a color conversion layer may be disposed on the nanorod LED. The color conversion layer may include quantum dots. Alternatively, display panel 10 may be a quantum dot light-emitting display panel that utilizes quantum dot light-emitting diodes (QNDs) including a quantum dot light-emitting layer as a display element. Alternatively, display panel 10 may be an inorganic light-emitting display panel that utilizes inorganic light-emitting elements including inorganic semiconductors as display elements.

The central display area CTDA may be configured at the center of the display panel 10. The corner display areas CDA may be configured between the central display area CTDA and the corners CN where they meet at the edges of the display panel 10. The corner CN may be defined as the portion where edges extending in different directions intersect. In one embodiment, if the display panel 10 is polygonal, the display panel 10 may include multiple corners CN.
[0141] In one embodiment, the display panel 10 may include a plurality of corner display areas CDA. For example, the display panel 10 may include a first corner display area CDA1, a second corner display area CDA2, a third corner display area CDA3, and a fourth corner display area CDA4. In one embodiment, the first corner display area CDA1 may be configured between the center display area CDA, a first edge position EG1, and a second edge position EG2.
[0142] The display panel 10 may include structures and / or materials that can be stretched and / or contracted. Therefore, the display panel 10 can be bent from a first direction (e.g., the x direction or -x direction) toward a third direction (e.g., the z direction or -z direction) and from a second direction (e.g., the y direction or -y direction) toward a third direction (e.g., the z direction or -z direction).
[0143] In one embodiment, in the corner display area CDA, the display panel 10 may include structures and / or materials that can be stretched and / or contracted. Therefore, the corner display area CDA can be bent from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction) and from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction).
[0144] In one embodiment, the deformation degree of the corner display area CDA can be greater than that of the central display area CTDA, and the magnitude of the stress acting on the corner display area CDA can be relatively greater than the magnitude of the stress acting on the central display area CTDA. When the corner display area CDA has a structure and / or material that allows it to stretch or contract, the magnitude of the stress acting on the corner display area CDA can be reduced, and damage to the display panel 10 in the corner display area CDA can be prevented or reduced. Of course, the central display area CTDA can also have a structure and / or material that allows it to stretch or contract.

[0190] Reference Figure 7 and Figure 8 The display panel 10 may have a through-hole TP extending through the display panel 10. No components of the display panel 10 may be disposed in the through-hole TP. Therefore, the display panel 10 can be stretched and / or contracted without damage. In other embodiments, the display panel 10 may not have the through-hole TP. In this case, the display panel 10 may include a material capable of being stretched and / or contracted. Hereinafter, a detailed description will focus on the case where the display panel 10 has the through-hole TP.
[0191] Reference Figure 7 The display panel 10 may include a pixel area PA and a connection area CA. The pixel area PA may be an area for configuring pixels PX. The pixel area PA may include a first pixel area PA1 and a second pixel area PA2. A first pixel PX1 may be configured in the first pixel area PA1.

[0192] Multiple pixel regions PA can be spaced apart in a first direction (e.g., the x-direction or the -x-direction) and / or a second direction (e.g., the y-direction or the -y-direction). In one embodiment, the multiple pixel regions PA can be spaced apart by a first interval d1 and a second interval d2, respectively. For example, the first pixel region PA1 and the second pixel region PA2 can be spaced apart in a first direction (e.g., the x-direction or the -x-direction) and / or a second direction (e.g., the y-direction or the -y-direction).
[0193] A connecting region CA can extend between adjacent pixel regions PA. In one embodiment, each pixel region PA can be connected to four connecting regions CA.

Similarly, in... Figure 7 In this context, two adjacent basic units U in the vertical direction can be vertically symmetrical about a symmetry axis located between them and parallel to the first direction (e.g., the x-direction or the -x-direction).
[0197] Among multiple basic units U, adjacent basic units U (e.g., Figure 7 The four basic units U shown form a closed line CC between them. The closed line CC can define a spacer region V as an empty space.

Hereinafter, a detailed description will focus on the case where the holes HL are provided in the first organic insulating layer 115 and the second organic insulating layer 116.
[0211] In some embodiments, the organic insulating layer OIL may have a groove recessed in the thickness direction of the organic insulating layer OIL instead of the hole HL. In some embodiments, the organic insulating layer OIL may not have the hole HL or the groove.
[0212] In one embodiment, a first inorganic layer PVX1 may be disposed between an interlayer insulating layer 114 and a first organic insulating layer 115. The first inorganic layer PVX1 may cover a first source electrode SE1, a first drain electrode DE1, a second source electrode SE2, and a second drain electrode DE2. In one embodiment, the first inorganic layer PVX1 may have contact holes to electrically connect the first source electrode SE1 or the first drain electrode DE1 to a connecting electrode CML.
[0213] In other embodiments, the first inorganic layer PVX1 may be disposed between the first organic insulating layer 115 and the second organic insulating layer 116.

The protruding top PT of the aperture HL and the second inorganic layer PVX2 can disconnect the first functional layer 212a and the second functional layer 212c, and the separated first and second functional layer patterns can be disposed inside the aperture HL. Therefore, moisture or oxygen can be prevented from flowing into the OLED from the through-hole TP, and damage to the OLED can be prevented. However, the structure that disconnects the first functional layer 212a and the second functional layer 212c is not limited to this.

The first inorganic encapsulation layer 310 can contact the protruding top PT of the second inorganic layer PVX2. The first inorganic encapsulation layer 310 can contact the first inorganic layer PVX1. Therefore, moisture or oxygen can be prevented from flowing into the OLED through the through-hole TP via the organic material layer. Furthermore, the first inorganic encapsulation layer 310 can be separated based on the through-hole TP.
[0223] An organic encapsulation layer 320 can be disposed on the first inorganic encapsulation layer 310. The organic encapsulation layer 320 can overlap with the first organic light-emitting diode (OLED1) and the second organic light-emitting diode (OLED2), and the organic encapsulation layer 320 can fill the via HL.

For example, the organic encapsulation layer 320 overlapping with the first organic light-emitting diode OLED1 can extend to the first dam DAM1. The organic encapsulation layer 320 overlapping with the second organic light-emitting diode OLED2 can extend to the second dam DAM2. The first dam DAM1 and the second dam DAM2 protrude from the upper surface of the second inorganic layer PVX2 in the thickness direction of the substrate 100, thus allowing control over the flow of the organic encapsulation layer 320.
[0224] The second inorganic encapsulation layer 330 can cover the organic encapsulation layer 320. The second inorganic encapsulation layer 330 can cover the substrate 100 entirely and continuously. The second inorganic encapsulation layer 330 can contact the first inorganic encapsulation layer 310 on the first dam portion DAM1 and the second dam portion DAM2. Therefore, the organic encapsulation layer 320 can be separated through the first dam portion DAM1 and the second dam portion DAM2. Furthermore, the second inorganic encapsulation layer 330 can be separated based on the through portion TP.
[0225] The following explains the control reference. Figures 1 to 9 Various embodiments of a control method for a display device 1 to bend a display panel 10 are described.

Figure 11a and Figure 11b It is a three-dimensional view schematically representing the shape of the display device 1 after it has been bent. Figure 11a This is a perspective view showing the front surface of the display unit 1100. Figure 11b This is a perspective view of the back of the display unit 1100.
[0227] Reference Figure 10 An image can be displayed in the display area DA of the display panel 10. The display panel 10 may include edge positions. In one embodiment, the display panel 10 may include a first edge position EG1 extending in a first direction (e.g., the x direction or the -x direction) and a second edge position EG2 extending in a second direction (e.g., the y direction or the -y direction).
[0228] In one embodiment, when the first edge position EG1 extends in a first direction (e.g., the x-direction or the -x-direction) and the second edge position EG2 extends in a second direction (e.g., the y-direction or the -y-direction), the display area DA of the display panel 10 can be a flat plane. When the display area DA is a flat plane, distortion can be prevented or reduced when multiple users view the image displayed on the display area DA. Furthermore, even when viewing the image of the display device 1 from various angles, distortion perceived by the user can be prevented or reduced.

[0230] Reference Figure 11a and Figure 11bThe controller 1700 can consider the obtained information to bend the display panel 10, such that the first edge position EG1 and the second edge position EG2 each have curvature. In one embodiment, when the display panel 10 is bent, the first edge position EG1 may have curvature. In this case, the position of a point of the second edge position EG2 may be changed in a first direction (e.g., the x-direction or the -x-direction). The position of a point of the second edge position EG2 may be changed in a direction closer to the center of the display panel 10. Furthermore, the position of a point of the second edge position EG2 may be changed in a third direction (e.g., the z-direction or the -z-direction). In particular, the position of a point of the second edge position EG2 may be changed in a third direction (e.g., the z-direction or the -z-direction). Figure 11a and Figure 11b The z-direction is changed.
[0231] In one embodiment, when the display panel 10 is bent, the second edge position EG2 may have curvature. In this case, the position of a point on the first edge position EG1 may be changed in a second direction (e.g., the y-direction or the -y-direction). The position of a point on the first edge position EG1 may be changed in a direction closer to the center of the display panel 10. Furthermore, the position of a point on the first edge position EG1 may be changed in a third direction (e.g., the z-direction or the -z-direction). In particular, the position of a point on the first edge position EG1 may be... Figure 11a and Figure 11b The z-direction is altered. Therefore, the display panel 10 can be changed to a concave shape. In this case, the sense of presence and / or immersion experienced by the user viewing the image displayed in the display area DA can be increased.
[0232] This concludes the explanation of the case where the display panel 10 is changed from a flat shape to a recessed shape, but the display panel 10 can also be changed from a recessed shape to a flat shape.
[0233] In embodiments of the present invention, the display panel 10 may include a flat state and a state in which the display panel 10 is bent into a concave shape. Therefore, the size of the space occupied by the display device 1 can be adjusted.
[0234] Embodiments of the present invention may take into account the information obtained by the controller 1700 to bend the display panel 10, such that the first edge position EG1 and the second edge position EG2 respectively have curvature. Therefore, embodiments of the present invention can provide users with various viewing experiences based on the obtained information, and can diversify the effective utilization of the display device 1.
[0235] Reference Figure 11bThe housing assembly 20 can bend the display panel 10. The housing assembly 20 can bend the display panel 10 from a first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction). The first edge position EG1 of the bent display panel 10 can have curvature.
[0236] In this specification, bending a constituent element from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction) means that the cross section of the constituent element intersecting a plane (e.g., the xz plane) extending in the first direction (e.g., the x-direction or -x-direction) and the third direction (e.g., the z-direction or -z-direction) is bent concavely or convexly.
[0237] The housing assembly 20 can bend the display panel 10 from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). In this case, the second edge position EG2 of the bent display panel 10 can have curvature.
[0238] In this specification, bending a constituent element from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction) means that the cross section of the constituent element intersecting a plane (e.g., the yz plane) extending in the second direction (e.g., the y-direction or -y-direction) and the third direction (e.g., the z-direction or -z-direction) is bent concavely or convexly.
[0239] The first housing 21 can extend in a first direction (e.g., the x-direction or the -x-direction) and can be configured behind the display panel 10. The first housing 21 can be bent from the first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction). The first housing 21 can be bent under the control of the controller 1700. Therefore, the first housing 21 can bend the display panel 10 from the first direction (e.g., the x-direction or the -x-direction) toward a third direction (e.g., the z-direction or the -z-direction). Furthermore, the first housing 21 can bend the display panel 10 so that the first edge position EG1 has curvature.
[0240] The second housing 23 can extend in a second direction (e.g., the y-direction or the -y-direction) and can be configured behind the display panel 10. The second housing 23 can be bent from the second direction (e.g., the y-direction or the -y-direction) toward a third direction (e.g., the z-direction or the -z-direction). The second housing 23 can be bent under the control of the controller 1700. Therefore, the second housing 23 can cause the display panel 10 to bend from the second direction (e.g., the y-direction or the -y-direction) toward a third direction (e.g., the z-direction or the -z-direction). Furthermore, the second housing 23 can cause the display panel 10 to bend so that the second edge position EG2 has curvature.
[0241] In one embodiment, the line 27 can bend the first housing 21 and / or the second housing 23. For example, the first housing 21 and / or the second housing 23 can be bent when the line 27 is contracted or when the length of the line 27 is shortened by a motor.
[0242] In one embodiment, the plurality of support members 25 may extend in a first direction (e.g., the x-direction or the -x-direction). In another embodiment, the plurality of support members 25 may be spaced apart from each other along a second direction (e.g., the y-direction or the -y-direction).
[0243] Multiple support members 25 can be bent from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction). In one embodiment, the first housing 21 can be bent from the first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction). For example, when the first housing 21 is bent from the first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction), the multiple support members 25 are also bent from the first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction). Therefore, the display panel 10 can be bent from the first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction).
[0244] At least one of the plurality of support members 25 is movable in a third direction (e.g., the z-direction or the -z-direction). For example, the support member 25 adjacent to the first edge position EG1 is movable in a third direction (e.g., the z-direction or the -z-direction). In one embodiment, the second housing 23 can move at least one of the plurality of support members 25 in a third direction (e.g., the z-direction or the -z-direction). For example, when the second housing 23 is bent from a second direction (e.g., the y-direction or the -y-direction) toward a third direction (e.g., the z-direction or the -z-direction), at least one of the plurality of support members 25 can move in a third direction (e.g., the z-direction or the -z-direction). Therefore, the display panel 10 can be bent from the second direction (e.g., the y-direction or the -y-direction) toward a third direction (e.g., the z-direction or the -z-direction).
[0245] The controller 1700 can obtain information to bend the display panel 10 and bend the display panel 10 in consideration of the obtained information. The controller 1700 may include a first drive unit 1710 and a second drive unit 1730.
[0246] The first drive unit 1710 can control the housing assembly 20. In one embodiment, the first drive unit 1710 can control the bending of the first housing 21 and / or the second housing 23. In one embodiment, the first drive unit 1710 may include a motor. The motor can cause the wire 27 to contract or wind around to reduce the length of the wire 27.
[0247] In one embodiment, the first drive unit 1710 may include multiple motors. The multiple motors can control the bending of the first housing 21 and the second housing 23, respectively. In one embodiment, the multiple motors can control the bending of one housing. For example, when multiple motors control the first housing 21, the bending of both ends of the first housing 21 can be adjusted independently. As another example, when multiple motors control the second housing 23, the bending of both ends of the second housing 23 can be controlled independently. Therefore, the display panel 10 can be bent in various shapes.
[0248] The second drive unit 1730 can control the display unit 1100 to rotate about a second direction (e.g., the y-direction or the -y-direction) as an axis. In one embodiment, the second drive unit 1730 may include a motor. The motor can rotate the display unit 1100 about a second direction (e.g., the y-direction or the -y-direction) as an axis. Therefore, the display panel 10 can be rotated about a second direction (e.g., the y-direction or the -y-direction) as an axis by the controller 1700.
[0249] Figure 12a It is Figure 11aA cross-sectional view of the curved display panel 10 along line EE′. Figure 12b It is Figure 11a A cross-sectional view of the curved display panel 10 along the FF′ line. Figure 12c It is Figure 11a A cross-sectional view of the curved display panel 10 along line GG′. Figures 12a to 12c In, with Figure 4 The same symbol represents the same component, so repeated descriptions are omitted.
[0250] Combination Figure 4 For reference Figures 12a to 12c The display panel 10 may include a display area DA. In the curved display panel 10, the display area DA may have a recessed shape. The display area DA may include a central display area CTDA and a corner display area CDA. The central display area CTDA may be disposed at the center of the display panel 10. The corner display area CDA may be disposed between the corner CN where the central display area CTDA meets the edge of the display panel 10.
[0251] The display panel 10 may include multiple corner display areas CDA. For example, the display panel 10 may include a first corner display area CDA1, a second corner display area CDA2, a third corner display area CDA3, and a fourth corner display area CDA4.
[0252] The corner display area CDA may have a first direction curvature and a second direction curvature. In this specification, the first direction curvature may be defined as the curvature of a cross section (e.g., xz section) in a first direction (e.g., the x direction or -x direction). The second direction curvature may be defined as the curvature of a cross section (e.g., yz section) in a second direction (e.g., the y direction or -y direction).
[0253] In one embodiment, the first corner display area CDA1 may have a first curvature C11 in a first direction and a first curvature C12 in a second direction. In one embodiment, the second corner display area CDA2 may have a second curvature C21 in a first direction and a second curvature C22 in a second direction. In one embodiment, the third corner display area CDA3 may have a third curvature in a first direction and a third curvature in a second direction. In one embodiment, the fourth corner display area CDA4 may have a fourth curvature in a first direction and a fourth curvature in a second direction.
[0254] Therefore, the bent display panel 10 may appear concave when viewed from a cross-section (e.g., xz section) in a first direction (e.g., the x direction or -x direction). The bent display panel 10 may also appear concave when viewed from a cross-section (e.g., yz section) in a second direction (e.g., the y direction or -y direction).
[0255] In one embodiment, at least one of the plurality of corner display areas (CDA) may not have a first directional curvature. In another embodiment, at least one of the plurality of corner display areas (CDA) may not have a second directional curvature.
[0256] In one embodiment, the first-direction curvature of any one of the plurality of corner display areas CDA can be the same as the first-direction curvature of another of the plurality of corner display areas CDA. For example, the first-direction first curvature C11 of the first corner display area CDA1 can be the same as the first-direction second curvature C21 of the second corner display area CDA2. In other embodiments, the first-direction curvature of any one of the plurality of corner display areas CDA can be different from the first-direction curvature of another of the plurality of corner display areas CDA. For example, the first-direction first curvature C11 of the first corner display area CDA1 can be different from the first-direction second curvature C21 of the second corner display area CDA2. The first-direction first curvature C11 of the first corner display area CDA1 can be less than or greater than the first-direction second curvature C21 of the second corner display area CDA2. The first-direction curvatures of the plurality of corner display areas CDA can be controlled by the controller 1700. Figure 11b The first housing 21 is used for adjustment.
[0257] In one embodiment, the second-direction curvature of any one of the plurality of corner display areas CDA can be the same as the second-direction curvature of another of the plurality of corner display areas CDA. For example, the second-direction first curvature C12 of the first corner display area CDA1 can be the same as the second-direction second curvature C22 of the second corner display area CDA2. In other embodiments, the first-direction curvature of any one of the plurality of corner display areas CDA can be different from the first-direction curvature of another of the plurality of corner display areas CDA. For example, the second-direction first curvature C12 of the first corner display area CDA1 can be different from the second-direction second curvature C22 of the second corner display area CDA2. The second-direction first curvature C12 of the first corner display area CDA1 can be less than or greater than the second-direction second curvature C22 of the second corner display area CDA2. The second-direction curvature of the plurality of corner display areas CDA can be controlled by the controller 1700. Figure 11b The second housing 23 is used for adjustment.
[0258] The display panel 10 may include structures and / or materials capable of being stretched and / or contracted. Therefore, the display panel 10 can be bent from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction) and can be bent from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). The controller 1700 can control the first housing 21 and the second housing 23 to bend the display panel 10 into various shapes.
[0259] Figure 13 This is an enlarged view of a portion of the display area of a bent display panel 10 according to one embodiment. Figure 13 In, with Figure 7 The same symbol represents the same component, so repeated descriptions are omitted.
[0260] Reference Figure 13 The display panel 10 may have a through portion TP extending through the display panel 10. No components of the display panel 10 may be disposed in the through portion TP. Therefore, the display panel 10 can be stretched and / or contracted without damage.
[0261] In one embodiment, the shape of the through portion TP in the bent display panel 10 can be deformed. In the bent display panel 10, the angle θ′ between the edge position CAE1 of the first connecting region CA1 and the edge position PAE2 of the second pixel region PA2 can be changed, the area or shape of the separating region V′ can be changed, and the position of the pixel region PA can also be changed.
[0262] By changing the aforementioned angle θ′, increasing the area of the separating region V′, and / or deforming its shape, each pixel region PA can be rotated at a predetermined angle. Through the rotation of each pixel region PA, the interval between pixel regions PA (e.g., the first interval d1′ and the second interval d2′) can vary with position.
[0263] A bent display panel 10 can generate stress in a first direction (e.g., the x-direction or -x-direction), a second direction (e.g., the y-direction or -y-direction), and / or a third direction (e.g., the z-direction or -z-direction). When the display panel 10 has a through-hole TP, the shape of the through-hole TP can be deformed in the bent display panel 10, reducing stress in the first direction (e.g., the x-direction or -x-direction), the second direction (e.g., the y-direction or -y-direction), and / or the third direction (e.g., the z-direction or -z-direction). Therefore, damage to the display panel 10 can be prevented or reduced.
[0264] Figure 14a and Figure 14bThis diagram illustrates an embodiment of the present invention where the display panel 10 is bent by considering information corresponding to the operation of a remote control. Figure 14a and Figure 14b In, with Figure 10 and Figure 11a The same symbol represents the same component, so repeated descriptions are omitted.
[0265] Reference Figure 14a and Figure 14b An image can be displayed in the display area DA of the display panel 10. The display panel 10 may include edge positions. In one embodiment, the display panel 10 may include a first edge position EG1 extending in a first direction (e.g., the x direction or the -x direction) and a second edge position EG2 extending in a second direction (e.g., the y direction or the -y direction).
[0266] The controller 1700 can obtain information to bend the display panel 10. The information obtained to bend the display panel 10 may be information corresponding to the operation of the remote control 1410 connected to the display device 1. Here, the information corresponding to the operation of the remote control 1410 may be an output signal generated corresponding to the operation of a user who selects a button or menu on the remote control 1410 to bend the display panel 10.
[0267] The controller 1700 can take into account information corresponding to the operation of the remote controller 1410 to bend the display panel 10, and can control the display panel 10 to display an image.
[0268] Reference Figure 14a The information corresponding to the operation of the remote control 1410 may be a first output signal corresponding to the operation of the remote control 1410 by a user who selects the first button 1411 of the remote control 1410. The controller 1700 may obtain the first output signal to bend the display panel 10, and control the display panel 10 to bend and display an image in consideration of the obtained first output signal. In one embodiment, the controller 1700 may control the first edge position EG1 and the second edge position EG2 to extend in a first direction (e.g., the x-direction or the -x-direction) and a second direction (e.g., the y-direction or the -y-direction), respectively. Therefore, the display panel 10 may be flat.
[0269] Reference Figure 14bThe information corresponding to the operation of the remote control 1410 may be a second output signal corresponding to the operation of the remote control 1410 by a user who selects the second button 1413 of the remote control 1410. The controller 1700 may obtain the second output signal to bend the display panel 10, and take into account the obtained second output signal to control the display panel 10 to bend and display an image. In one embodiment, the controller 1700 may take into account the second output signal to bend the display panel 10 such that the first edge position EG1 and the second edge position EG2 respectively have curvature.
[0270] Figure 14b This describes a case where there is only one second button 1413; however, in other embodiments, there may be multiple second buttons 1413. In this case, the information corresponding to the operation of the remote control 1410 may be a second output signal corresponding to the operation of the remote control 1410 by a user who selects at least one of the multiple second buttons 1413. In one embodiment, the controller 1700 may consider the second output signal corresponding to the operation of the remote control 1410 by a user who selects at least one of the multiple second buttons 1413 to control the degree to which the display panel 10 is bent from a first direction (e.g., the x-direction or -x-direction) toward a third direction (e.g., the z-direction or -z-direction). In one embodiment, the controller 1700 may consider the second output signal corresponding to the operation of the remote control 1410 by a user who selects another of the multiple second buttons 1413 to control the degree to which the display panel 10 is bent from a second direction (e.g., the y-direction or -y-direction) toward a third direction (e.g., the z-direction or -z-direction). Therefore, the user can view images displayed on the display panel 10, which is bent in various shapes.
[0271] Figure 15a and Figure 15b This diagram illustrates an embodiment of the present invention where the display panel 10 is bent by considering information corresponding to the user's voice signal. Figure 15a and Figure 15b In, with Figure 14a and Figure 14b The same symbol represents the same component, so repeated descriptions are omitted.
[0272] Reference Figure 15a and Figure 15b An image can be displayed in the display area DA of the display panel 10. The display panel 10 may include edge positions. In one embodiment, the display panel 10 may include a first edge position EG1 extending in a first direction (e.g., the x direction or the -x direction) and a second edge position EG2 extending in a second direction (e.g., the y direction or the -y direction).
[0273] The controller 1700 can obtain information to bend the display panel 10. The information obtained to bend the display panel 10 may be information corresponding to the audio signal of the user viewing the image.
[0274] The controller 1700 can obtain information corresponding to the user's voice signal in order to bend the display panel 10, and take into account the obtained information corresponding to the user's voice signal to control the display panel 10 to bend and display an image.
[0275] Reference Figure 15a The user's voice signal can be a pre-set first voice signal. For example, the pre-set first voice signal can be a voice signal that implies a desired flat image display. In this case, the controller 1700 can control the first edge position EG1 and the second edge position EG2 to extend in a first direction (e.g., the x-direction or -x-direction) and a second direction (e.g., the y-direction or -y-direction), respectively. Therefore, the display panel 10 can be flat.
[0276] Reference Figure 15b The user's voice signal can be a pre-set second voice signal. For example, the pre-set second voice signal could be a voice signal meaning "Please provide the image with a curved surface." Alternatively, the pre-set second voice signal could be a voice signal meaning "Please provide the image only to me." In this case, the controller 1700 can take the obtained information into account to control the bending of the display panel 10, such that the first edge position EG1 and the second edge position EG2 each have curvature.
[0277] Figure 16a and Figure 16b This diagram illustrates an embodiment of the present invention where the display panel 10 is bent taking into account the types of content included in the image. Figure 16a and Figure 16b In, with Figure 14a and Figure 14b The same symbol represents the same component, so repeated descriptions are omitted.
[0278] Reference Figure 16a and Figure 16b An image can be displayed in the display area DA of the display panel 10. The display panel 10 may include edge positions. In one embodiment, the display panel 10 may include a first edge position EG1 extending in a first direction (e.g., the x direction or the -x direction) and a second edge position EG2 extending in a second direction (e.g., the y direction or the -y direction).
[0279] The controller 1700 can obtain information to bend the display panel 10. The information obtained to bend the display panel 10 may be related to the type of content included in the image. In one embodiment, the information related to the type of content included in the image can be obtained from metadata of the content included in the image.
[0280] Reference Figure 16a The content included in the image can be a pre-defined first content category. For example, the pre-defined first content category could be that the image includes at least one of the following: news, telephone shopping, or a TV series. In this case, the controller 1700 can control the first edge position EG1 and the second edge position EG2 to extend in a first direction (e.g., the x-direction or the -x-direction) and a second direction (e.g., the y-direction or the -y-direction), respectively. Therefore, the display panel 10 can be flat.
[0281] Reference Figure 16b The content included in the image can be a pre-defined second content category. For example, the pre-defined second content category could be that the image includes at least one content from movies and games. In this case, the controller 1700 can take the obtained information into account to control the display panel 10 to bend, such that the first edge position EG1 and the second edge position EG2 each have curvature.
[0282] Figure 17 , Figure 18 as well as Figures 19a to 19c This is a diagram illustrating an embodiment of the present invention in which the display panel 10 is bent taking into account the user's position. Figure 17 , Figure 18 as well as Figures 19a to 19c This represents the xz section of the display panel 10.
[0283] Reference Figure 17 An image can be displayed in the display area DA of the display panel 10. In one embodiment, the display area DA may include a first display area DA1, a second display area DA2, and a third display area DA3. In one embodiment, the second display area DA2 and the third display area DA3 may be configured at both ends of the first display area DA1 in a first direction (e.g., the x-direction or the -x-direction).
[0284] The display panel 10 may include an edge location. In one embodiment, the display panel 10 may include a first edge location extending in a first direction (e.g., the x-direction or the -x-direction). Figure 17 , Figure 18 as well as Figures 19a to 19c(not shown in the image) and a second edge position EG2 extending in a second direction (e.g., the y direction or the -y direction).
[0285] The controller 1700 can obtain information to bend the display panel 10. The information obtained to bend the display panel 10 may be information regarding the position of at least one user. In one embodiment, the user's position may be defined as the position of the user's head relative to the display panel 10.
[0286] In one embodiment, the location information of the at least one user may be the location information of one user. In other embodiments, the location information of the at least one user may be the location information of multiple users.
[0287] In one embodiment, the controller 1700 may use a position sensor of the display device 1 to obtain information about the user's position. The position sensor may be, for example, a laser displacement sensor, an ultrasonic displacement sensor, etc.
[0288] The controller 1700 can consider information about the user's position to bend the display panel 10, such that the first edge position and the second edge position EG2 each have a curvature. In one embodiment, the controller 1700 can consider information set by the user to bend the display panel 10, such that it has a preset curvature at the first edge position and a preset curvature at the second edge position EG2. For example, if the position of the at least one user is a single user's position information, the controller 1700 can bend the display panel 10, such that the first edge position and the second edge position EG2 each have a curvature. As another example, if the position information of the at least one user is the position information of multiple users, the controller 1700 can maintain the display panel 10 in a flat shape. As yet another example, if the position information of the at least one user is the position information of multiple users, the controller 1700 can consider any one of the multiple user position information to bend the display panel 10, such that the first edge position and the second edge position EG2 each have a curvature.
[0289] In one embodiment, the controller 1700 can bend the display panel 10 so that the center of curvature CT of the display panel 10 is aligned with the user's position. The center of curvature CT of the display panel 10 can be the center of curvature at a first edge position and the center of curvature at a second edge position EG2.
[0290] Reference Figure 18The user's position can be changed. In one embodiment, the user's position can be changed in a first direction (e.g., the x-direction or the -x-direction) and / or a third direction (e.g., the z-direction or the -z-direction).
[0291] The controller 1700 can obtain information to bend the display panel 10. In one embodiment, the controller 1700 can compare information about the user's position with a preset center of curvature CT of the display panel 10.
[0292] Reference Figures 19a to 19c If the information about the user's position is inconsistent with the preset curvature center CT of the display panel 10, the controller 1700 can make the information about the user's position consistent with the curvature center CT of the display panel 10.
[0293] Reference Figure 19a The controller 1700 can rotate the display panel 10 about an axis AX in a second direction (e.g., the y-direction or the -y-direction).
[0294] Reference Figure 19b and Figure 19c The controller 1700 may take into account the obtained information to bend the display panel 10 so that the first edge position and the second edge position EG2 respectively have curvature.
[0295] Reference Figure 19b When the distance from the user to the display panel 10 increases, at least one of the curvature of the first edge position and the curvature of the second edge position EG2 can decrease. The distance from the user to the display panel 10 can be defined as the distance from the center of the display panel 10 to the user's position. In this case, the curvature of the first display area DA1, the second display area DA2, and the third display area DA3 can decrease. That is, the degree to which the first display area DA1, the second display area DA2, and the third display area DA3 are bent can decrease relatively. In other embodiments, when the distance from the user to the display panel 10 decreases, at least one of the curvature of the first edge position and the curvature of the second edge position EG2 can increase. In this case, the curvature of the first display area DA1, the second display area DA2, and the third display area DA3 can increase.
