Description

Display device and method of operation thereof

[0001] The present disclosure relates to a display device. More specifically, the present disclosure relates to a display device capable of changing the curvature of a display panel.

[0002] As the information society develops, the demand for display devices is also increasing in various forms, and in response to this, various display devices such as LCD (Liquid Crystal Display Device), ELD (Electro luminescent Display), VFD (Vacuum Fluorescent Display), and OLED (Organic Light Emitting Diode) are being researched and used in recent years.

[0003] Among these, OLED panels display images by depositing a self-luminous organic layer on a substrate formed with a transparent electrode. OLED panels are not only thin but can also be flexible. Much research is being conducted on the structural characteristics of display devices equipped with such OLED panels.

[0004] Recently, flexible displays capable of bending have emerged. Conventionally, the curvature of a flexible display was adjusted by pressing a key on a remote control device, then adjusting the curvature in a multi-step screen entry mode, or by pressing a button on a joystick, then adjusting the curvature in a multi-step screen entry mode.

[0005] This method had the problem that it was inconvenient to adjust the curvature, and thus the usability of the curvature adjustment function was reduced.

[0006] The present disclosure aims to solve the above-mentioned and other problems.

In this case, the image displayed on the flexible display (110) can be a still image or a moving image, and can be a 2D image or a 3D image.

[0099] In addition, the controller (170) can control the playback of content stored in the display device (100), received broadcast content, or external input content input from outside, and the content can be in various forms such as broadcast video, external input video, audio file, still image, connected web screen, and document file.

[0100] The wireless communication interface (173) can communicate with an external device through wired or wireless communication. The wireless communication interface (173) can perform short-range communication with the external device. To this end, the wireless communication interface (173) can support short-range communication using at least one of Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technologies. This wireless communication interface (173) can support wireless communication between the display device (100) and a wireless communication system, between the display device (100) and another display device (100), or between the display device (100) and a network in which the display device (100, or an external server) is located via a short-range wireless communication network (Wireless Area Network). The short-range wireless communication network can be a short-range wireless personal area network (Wireless Personal Area Network).

[0101] Here, the other display device (100) may be a wearable device (e.g., a smartwatch, smart glasses, a head-mounted display (HMD)) or a mobile terminal such as a smart phone that can exchange data with (or be linked to) the display device (100) according to the present invention. The wireless communication interface (173) may detect (or recognize) a wearable device capable of communication around the display device (100).

[0102] Furthermore, if the detected wearable device is a device certified to communicate with the display device (100) according to the present invention, the controller (170) can transmit at least a portion of the data processed in the display device (100) to the wearable device via the wireless communication interface (173). Accordingly, a user of the wearable device can utilize the data processed in the display device (100) via the wearable device.

[0103] The flexible display (110) can generate a driving signal by converting a video signal, data signal, OSD signal processed by the controller (170) or a video signal, data signal, etc. received from an external device interface (135) into R, G, and B signals, respectively.

[0104] Meanwhile, since the display device (100) illustrated in FIG. 9 is merely an embodiment of the present invention, some of the illustrated components may be integrated, added, or omitted depending on the specifications of the display device (100) actually implemented.

[0105] That is, two or more components may be combined into a single component, or a single component may be subdivided into two or more components, as needed. Furthermore, the functions performed by each block are intended to illustrate embodiments of the present invention, and their specific operations or devices do not limit the scope of the present invention.

[0106] According to another embodiment of the present invention, the display device (100) may receive and play back an image through a network interface (133) or an external device interface (135) without having a tuner (131) and a demodulator (132), unlike as shown in FIG. 9.

[0107] For example, the display device (100) may be implemented separately as an image processing device, such as a set-top box, for receiving broadcast signals or contents according to various network services, and a content playback device for playing contents input from the image processing device.

[0108] In this case, the operating method of the display device according to the embodiment of the present invention described below may be performed by any one of the following: a display device (100) as described with reference to FIG. 9, an image processing device such as the separated set-top box, or a content playback device having a flexible display (110) and a speaker (185).

[0109] FIG. 10 is a flowchart for explaining an operating method of a display device according to an embodiment of the present disclosure.

[0110] Hereinafter, the mode for adjusting the curvature of the flexible display (110) may be referred to as a curvature adjustment mode. The curvature adjustment mode may be entered (or activated) in various ways.

[0111] In one embodiment, the controller (170) may enter the operation mode of the flexible display (110) into the curvature adjustment mode when a specific gesture is detected on a part of the user's body or through a part of the body. For example, the controller (170) may enter the operation mode of the flexible display (110) into the curvature adjustment mode when a specific gesture is detected for a specific period of time at a location a specific distance away from the center of the flexible display (110). A specific gesture corresponding to a part of the user's body may be detected by a sensor (800) described below.

[0112] In another embodiment, the curvature adjustment mode may be entered upon receipt of a user's preset voice command.

[0113] In another embodiment, the curvature adjustment mode can be entered based on a setting in the menu.

[0114] In another embodiment, the curvature control mode may be entered upon receiving either a specific input from a mouse or a specific input from a keyboard that controls the operation of the display device (100).

[0115] The following explanation assumes that the curvature control mode is activated.

[0116] Referring to FIG. 10, the controller (170) can obtain sensing information through the sensor (800) (S1001).

[0117] In one embodiment, the sensor (800) may be a sensor used to recognize a user's gesture. The sensor (800) may include one or more of a TOF (Time Of Flight) sensor, a camera sensor, an infrared sensor, an ultrasonic sensor, or a radar sensor.

[0118] A TOF sensor may be a sensor that measures the distance to an object using light (e.g., infrared rays). If the sensor (800) is a TOF sensor, the sensing information may include the distance between the object and the TOF sensor (or the flexible display). If the sensor (800) is a camera sensor, the sensing information may include image information regarding the front of the display device (100).

[0119] Explains the operating principle of the TOF sensor.

[0120] FIG. 11 is a drawing explaining the operating principle of a TOF sensor according to an embodiment of the present disclosure.

[0121] Referring to FIG. 11, the TOF sensor (1101) may be an example of the sensor (800) illustrated in FIG. 8.

[0122] The TOF sensor (1101) can transmit light to an object, receive light reflected from the object, and calculate the distance between the object and the TOF sensor (1101) using the round-trip time of the light and the speed of light.

[0123] The TOF sensor (1101) can transmit distance information based on the calculated distance to the controller (170) via I2C communication. The distance information can include a plurality of distance values ​​corresponding to each of a plurality of square areas included in a sensor area (1110) formed by the TOF sensor (1101). For example, the sensor area (1110) can include 64 square areas.

[0124] The controller (170) can determine which part of the plurality of square areas is covered and how far it is from the object based on the plurality of distance values ​​included in the distance information.

[0125] For example, when a hand is brought to the front of the TOF sensor (1101), the distance values ​​corresponding to each of the areas located in the center among the 64 square areas may be output as small. Then, when a hand is brought to the left side of the TOF sensor (1101), the distance values ​​of each of the areas located on the left side of the sensor area (1110) may be output as small, and when a hand is brought to the right side of the TOF sensor (1101), the distance values ​​of each of the areas located on the left side of the sensor area (1110) may be output as small.

[0126] The controller (170) can receive distance information from the TOF sensor (1101) at each of a plurality of time points. For example, the TOF sensor (1101) can transmit distance information sequentially measured at each of a total of four time points (or four frames) to the controller (170).

[0127] The controller (170) can determine the movement direction of an object (or gesture) located in front of the TOF sensor (1101) based on distance information measured at each of the four viewpoints. For example, it is assumed that the TOF sensor (1110) sequentially transmits first to fourth distance information to the controller (170). The controller (170) can determine that the object has moved from left to right when the distance values ​​of areas located on the left side of the sensor area (1110) are small through the first distance information, the distance values ​​of areas located in the center of the sensor area (1110) are small through the second and third distance information, and the distance values ​​of areas located on the right side of the sensor area (1110) are small through the fourth distance information.

[0128] The controller (170) can identify the movement of an object from distance information using an artificial intelligence model trained through supervised learning. The training data set of the artificial intelligence model may include four training distance information for four viewpoints and the movement direction of the labeled object. The artificial intelligence model may be stored in the memory (140) and trained to minimize a loss function representing the difference between the label vector corresponding to the labeled movement direction and the feature vector corresponding to the inferred movement direction.

[0129] The artificial intelligence model may be an artificial neural network-based model that infers the direction of movement of an object from four pieces of distance information.

[0130] When the controller (170) receives four pieces of distance information from the TOF sensor (1101), it can input the four pieces of distance information into an artificial intelligence model to obtain the direction of movement of the object.

[0131] The controller (170) can determine the type (or shape) of a gesture based on the distance information received from the TOF sensor (1101). For example, the controller (170) can obtain a depth map using the received distance information, and can distinguish the user's hand from the background using the obtained depth map. The depth map is a map indicating the depth difference (distance difference) between square areas, and the controller (170) can extract the shape of the hand by excluding the separated background.

[0132] Again, Figure 10 is explained.

[0133] The controller (170) can recognize the user's gesture based on the acquired sensing information (S1003).

[0134] A user gesture can be an action where the user uses a body part to issue a command or express an intention. A user gesture can be either a hand gesture using the hand or a face gesture using the face, but these are examples only.

[0135] In the following, gestures are explained assuming that they are user hand gestures.

[0136] The controller (170) can identify the user's hand through sensing information and identify the gesture of the identified hand. The controller (170) can identify the user's hand through the camera sensor included in the sensor (800).

[0137] Recognizing a gesture may include at least one of recognizing the gesture itself, recognizing the movement of the gesture, or recognizing the degree of movement of the gesture.

[0138] The controller (170) can recognize at least one of the movement direction of the gesture or the type of the gesture based on the sensing information.

[0139] The direction of movement of the gesture may be any one of the following: a first direction moving from bottom to top, a second direction moving from top to bottom, a third direction moving from left to right, a fourth direction moving from right to left, a fifth direction moving from back to front, or a sixth direction moving from front to back.

[0140] If the gesture is a hand gesture, the type of hand gesture may be any of the following: a motion of giving a hand, a motion of extending a hand, or a motion of extending one or more fingers.

[0141] The method of recognizing the movement direction of a gesture or the type of gesture is replaced with the description in Fig. 11.

[0142] The controller (170) can adjust the curvature of the flexible display (110) according to the recognized gesture (S1005).

[0143] Adjusting the curvature of the flexible display (110) may be adjusting the degree of bending of the flexible display (110). Adjusting the curvature of the flexible display (110) may be adjusting the radius of curvature of the flexible display (110). The curvature and the radius of curvature of the flexible display (110) may be inversely proportional to each other. Increasing the curvature of the flexible display (110) may be decreasing the radius of curvature of the flexible display (110), and decreasing the curvature of the flexible display (110) may be increasing the radius of curvature of the flexible display (110).

[0144] The controller (170) can control the curvature of the flexible display (110) by providing a control signal to the driving unit (600). The controller (170) can control the operation of the motor (610) by applying a control signal to a motor driver (not shown) provided in the driving unit (600). The curvature of the flexible display (110) can be adjusted according to the operation of the motor (610).

[0145] In one embodiment, the controller (170) can recognize the movement of a recognized gesture and adjust the curvature of the flexible display (110).

[0146] For example, the controller (170) can adjust the curvature of the flexible display (110) based on the degree of movement of the gesture.

[0147] FIGS. 12A to 12C are drawings illustrating an example of adjusting the curvature of a flexible display based on the degree of movement of a gesture according to one embodiment of the present disclosure.

[0148] FIGS. 12A to 12C are diagrams that embody steps S1003 and S1005 of FIG. 10. Steps S1201 to S1209 below may be steps that embody step S1003 of FIG. 10, and step S1211 may be a step that embodies step S1005 of FIG. 10.

[0149] Referring to FIG. 12a, the controller (170) can determine whether a preset gesture has been detected based on sensing information acquired through the sensor (800) (S1201).

[0150] In one embodiment, the preset gesture may be a hand gesture having a specific form. For example, the preset gesture may be a hand gesture (1201) extending only the index finger and thumb, as illustrated in FIG. 12b.

[0151] When a preset gesture is detected, the controller (170) can store the first location of the detected gesture in the memory (140) (S1203).

[0152] The first position of the gesture may be a first distance between the detected gesture and the flexible display (110). Referring to FIG. 12B, the controller (170) may store the first distance between the hand gesture (1201) measured by the TOF sensor (1101) and the flexible display (110) in the memory (140). In FIG. 12B, the curvature of the flexible display (110) may be the first curvature.

[0153] When the controller (170) detects that the detected gesture has moved (S1205), it can obtain the second position of the gesture according to the movement of the gesture (S1207).

[0154] The controller (170) can detect that the detected gesture is moved in a preset direction, and if the gesture is moved in the preset direction, can obtain a second distance between the moved gesture and the flexible display (110) as a second position. The controller (170) can measure the second distance between the hand gesture (1201) and the flexible display (110) through the TOF sensor (1101).

[0155] The controller (170) can obtain the difference between the first position of the stored gesture and the obtained second position (S1209).

[0156] The controller (170) can obtain the difference between the first distance and the second distance as the degree of movement of the gesture.

[0157] The controller (170) can adjust the curvature of the flexible display (110) based on the acquired difference (S1211).

[0158] The memory (140) may store a plurality of degrees of movement of the gesture and the curvature of the flexible display (110) matching each degree of movement. The controller (170) may extract a curvature matching the degree of movement (difference between the first position and the second position) obtained from the memory (140) and adjust the curvature of the flexible display (110) to the extracted curvature.

[0159] The controller (170) can adjust the curvature of the flexible display (110) to a greater degree as the degree of movement of the gesture increases, and can adjust the curvature of the flexible display (110) to a smaller degree as the degree of movement of the gesture decreases.

[0160] As illustrated in FIG. 12c, the controller (170) may increase the curvature of the flexible display (110) from the first curvature to the second curvature when the distance between the hand gesture (1201) and the flexible display (110) increases from the first distance to the second distance. The second curvature may be a curvature that matches the difference between the second distance and the first distance.

[0161] In this way, according to embodiments of the present disclosure, a user can easily control the curvature of a flexible display with a simple gesture. This can improve the user experience of the display device.

[0162] Again, Figure 9 is explained.

[0163] As another example, the controller (170) can adjust the curvature of the flexible display (110) based on the movement direction of the gesture.

[0164] For example, the controller (170) can increase the curvature of the flexible display (110) when the movement direction of the gesture is in the first direction, and can decrease the curvature of the flexible display (110) when the movement direction of the gesture is in the second direction.

[0165] The controller (170) can reduce the curvature of the flexible display (110) as the distance between the recognized gesture and the flexible display (110) becomes closer, and can increase the curvature of the flexible display (110) as the distance between the recognized gesture and the flexible display (110) becomes farther.

[0166] As another example, the controller (170) can perform a curvature control operation of the flexible display (110) that matches the movement direction of the gesture.

[0167] As another example, the controller (170) can perform a curvature control operation of the flexible display (110) that matches the type of gesture.

[0168] FIGS. 13A and 13B are diagrams illustrating an example of controlling a flexible display based on a movement direction of a gesture according to one embodiment of the present disclosure.

[0169] FIG. 13A and FIG. 13B are diagrams that embody steps S1003 and S1005 of FIG. 10. Step S1301 may be an operation that embodies step S1003 of FIG. 10, and steps S1303 and S1305 may be operations that embody step S1005 of FIG. 10.

[0170] Referring to FIG. 13a, the controller (170) can detect the movement direction of the gesture based on sensing information acquired through the sensor (800) (S1301).

[0171] The process of detecting the movement direction of the gesture is replaced with the description in Fig. 11.

[0172] The controller (170) can determine whether a control operation for controlling the curvature of the flexible display (110) matching the movement direction of the detected gesture is stored in the memory (140) (S1303).

[0173] The memory (140) may store a first table (1300) that matches the movement direction of the gesture with the control operation of the flexible display (110), as illustrated in FIG. 13b. The movement direction of the gesture may be any one of an up direction moving from the bottom to the top, a down direction moving from the top to the bottom, a left direction moving from the right to the left, a right direction moving from the left to the right, and a push direction moving from the back to the front.

[0174] The control operation of the flexible display (110) may be referred to as a control mode.

[0175] A control operation that activates the operation of the TOF sensor (1101) may be matched to the up direction. A control operation that deactivates the operation of the TOF sensor (1101) may be matched to the down direction. A control operation that bends the flexible display (110) may be matched to the left direction. A control operation that flattens the flexible display (110) may be controlled to the right direction. A control operation that stops the curvature adjustment of the flexible display (110) may be matched to the push direction.

[0176] If the controller (170) determines that a control operation matching the movement direction of the gesture is stored in the memory (140), the controller (170) can perform the matching control operation (S1305).

[0177] The controller (170) can extract a control operation of the flexible display (110) that matches the movement direction of the gesture detected from the first table (1300) and perform the extracted control operation.

[0178] In this way, according to an embodiment of the present disclosure, since the movement of the flexible display is automatically performed to match the movement direction of the gesture, the user can control the flexible display without a complicated process, thereby greatly improving the user experience.

[0179] FIGS. 14A and 14B are diagrams illustrating examples of controlling a flexible display based on a type of gesture according to one embodiment of the present disclosure.

[0180] FIG. 14a and FIG. 14b are diagrams that embody steps S1003 and S1005 of FIG. 10. Step S1401 may be an operation that embodies step S1003 of FIG. 10, and steps S1403 and S1405 may be operations that embody step S1005 of FIG. 10.

[0181] The controller (170) can detect the type of gesture based on sensing information acquired through the sensor (800) (S1401).

[0182] The method for detecting the type of gesture is replaced with the description in Fig. 11.

[0183] The controller (170) can determine whether a control operation of the flexible display (110) matching the type of detected gesture is stored in the memory (140) (S1403).

[0184] The memory (140) may store a second table (1400) that matches the type of gesture with the control operation of the flexible display (110), as illustrated in FIG. 14b. The type of gesture may be any one of the following: an open palm type that opens a fist, a thumbs up type that raises a thumb, a V sign type that indicates a V, a raised index finger type that raises an index finger, or an OK sign type that connects the thumb and index finger in a circle.

[0185] The open palm type may be matched with a control action that activates the operation of the TOF sensor (1101). The thumbs up type may be matched with a control action that deactivates the operation of the TOF sensor (1101). The V sign type may be matched with a control action that bends the flexible display (110). The raised index finger type may be matched with a control action that flattens the flexible display (110). The OK sign type may be matched with a control action that stops the curvature adjustment of the flexible display (110).

[0186] If a control operation of a flexible display (110) matching the type of detected gesture is stored in the memory (140), the controller (170) can perform a control operation of the matching flexible display (110) (S1405).

[0187] The controller (170) can extract a control operation of the flexible display (110) that matches the type of gesture detected from the second table (1400) and perform the extracted control operation.

[0188] In this way, according to an embodiment of the present disclosure, since the operation of the flexible display matching the type of gesture is automatically performed, the user can control the flexible display without a complicated process, thereby greatly improving the user experience.

[0189] FIG. 15 is a drawing illustrating a radius of curvature of a flexible display matching an identified user according to one embodiment of the present disclosure.

[0190] In Fig. 15, it is assumed that the curvature adjustment mode of the flexible display (110) is activated.

[0191] Referring to FIG. 15, the memory (140) may store a third table (1300) including user identification information and a radius of curvature of the flexible display (110) matched to the user identification information.

[0192] The controller (170) can identify a user located in front of the flexible display (110) using image data acquired through a camera sensor included in the sensor (800). When the display device (100) is initially powered on, the controller (170) can recognize the user's face through the camera sensor and identify the user whose face has been recognized.

[0193] The controller (170) can verify the identification information of the identified user and extract the radius of curvature matching the identification information of the identified user from the third table (1500).

[0194] The controller (170) can adjust the curvature of the flexible display (110) to have the extracted curvature radius. For example, if the user identification information is A, the controller (170) can adjust the curvature of the flexible display (110) to have a curvature radius (1000R) matching A.

[0195] According to another embodiment of the present disclosure, the controller (170) can adjust the curvature of the flexible display (110) depending on the type of content image being played on the flexible display (110). For example, if the type of content image is a game image type, the controller (170) can increase the curvature of the flexible display (110), and if the type of content image is a static image type, the controller (170) can decrease the curvature of the flexible display (110).

[0196] The process of adjusting the curvature of the flexible display (110) depending on the type of content video can be performed after step S1005 of FIG. 10.

[0197] According to another embodiment of the present disclosure, the controller (170) can adjust the curvature of the flexible display (110) according to the type of content image played on the flexible display (110) and the distance between the user (or the user's gesture) and the flexible display (110).

[0198] The controller (170) can automatically adjust the curvature of the flexible display (110) based on the distance between the flexible display (110) and the user when a game image is being played on the flexible display (110). For example, when the distance between the flexible display (110) and the user is less than a certain distance during the playback of the game image, the controller (170) can increase the curvature of the flexible display (110), and when the distance between the flexible display (110) and the user is greater than a certain distance during the playback of a general video (e.g., a drama video), the controller (170) can decrease the curvature of the flexible display (110).

[0199] More specifically, the controller (170) can adjust the curvature of the flexible display (110) to a preset curvature (e.g., 900R) when the distance between the flexible display (110) and the user is less than a predetermined distance and a game image is being played on the flexible display (110), and can adjust the curvature radius of the flexible display (110) to a maximum curvature radius (corresponding to a flat screen) when the distance between the flexible display (110) and the user is greater than a predetermined distance and a general video is being played.

[0200] FIG. 16 is a drawing illustrating a configuration of a display device according to another embodiment of the present disclosure.

[0201] Referring to FIG. 16, the display device (100-1) may include a flexible display (110), a first sensor (1601), a second sensor (1602), a motor driver (1603), a motor (610), and a controller (170).

[0202] The first sensor (1601) may be a sensor for recognizing a gesture located in front of the flexible display (110). The first sensor (1601) may be the sensor (800) described in FIG. 8. The first sensor (1601) may be a TOF sensor (1101).

[0203] The second sensor (1602) may be a sensor positioned on the surface or inside of the flexible display (110) to detect the curvature of the flexible display (110). The second sensor (1602) may be a photo sensor. A photo sensor may be a sensor that generates an electrical signal in response to light.

[0204] When the flexible display (110) is bent, the amount of light reaching the photo sensor or the path of the light may change. The controller (170) may measure the curvature of the flexible display (110) based on the amount of light received from the photo sensor or the path of the light. The controller (170) may recognize the maximum curvature of the flexible display (110) based on the amount of light received from the photo sensor or the path of the light. Upon recognizing the maximum curvature of the flexible display (110), the controller (170) may output a notification indicating that the maximum curvature has been reached or may stop adjusting the curvature of the flexible display (110).

[0205] The motor driver (1603) can generate a motor control signal according to a control signal received from the controller (170) and transmit the generated motor control signal to the motor (610).

[0206] The motor (610) can be driven according to a motor control signal received from the motor driver (1603). As the rotational force provided by driving the motor (610) is transmitted through the gear sets (620, 630, 640), the inner wing (710) and the outer wing (730) can pivot about the pivot axis (WA).

[0207] The controller (170) can control the overall operation of the display device (100-1). The controller (170) can perform operations according to the embodiments of FIGS. 10 to 15.
