Description

Display device and control method thereof

[0001] The present invention relates to a display device that can rotate and change its mounting direction and a control method therefor.

[0002] As the information society develops, the demand for display devices is also increasing in various forms, and in response to this, recent display devices include liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), and electroluminescence devices.

[0003] The liquid crystal panel of the liquid crystal display device includes a liquid crystal layer and a TFT substrate and a color filter substrate facing each other with the liquid crystal layer interposed therebetween, and can display an image using light provided from a backlight unit.

[0004] As an example of an electroluminescent device (ELD), an active-matrix type organic light-emitting display device is commercially available. Because OLED displays are self-luminous, they do not require a backlight and offer advantages over liquid crystal displays (LCDs) in terms of response speed, viewing angle, and other factors. Therefore, they are attracting attention as next-generation display components.

[0005] Recently, there's a growing preference for display devices that are freely movable, rather than fixed. There's a growing need to improve work efficiency by allowing the display device to be moved freely within the office. There's also a growing need for display devices that offer both portability and convenient stand-alone functionality for outdoor use, such as camping.

[0006] The purpose of the present invention is to provide a display device that can rotate and change its mounting direction and a control method thereof.

[0007] A display device is provided, comprising: a main body having a display module including a touch sensor; a stand for supporting the main body to maintain a predetermined angle with respect to a surface; a rotation module for rotatably connecting the main body to the stand; a motion sensor for detecting movement of the main body; and a control unit for controlling a screen output to the display module, wherein the control unit detects a touch input to the display module and a user's operation for changing the mounting direction of the main body, and does not execute a control command corresponding to coordinates at which the touch input is recognized.

[0008] The above control unit can determine that the operation has been detected when the motion sensor detects a change in the mounting direction of the main body.

[0009] The above control unit can determine that the operation has been detected when the motion sensor detects an acceleration change greater than a reference value.

[0010] The above control unit can detect the operation when it includes two or more touch inputs in an area adjacent to an edge of the display unit module.

[0011] The above control unit can detect the operation when the touch input includes a reference area or more in an area adjacent to the edge of the display unit module.

[0012] The above touch input includes a touch contact that touches the touch sensor and a touch release that moves away from the touch sensor, and the control unit can determine whether or not the operation is performed between the touch contact and the touch release.

[0013] The control unit may determine that the operation is performed when the time between the touch contact and the touch release in an area adjacent to the edge of the display module lasts longer than a reference time.

[0014] A step of detecting a touch contact on a display module including a touch sensor; a step of detecting an operation operation for changing the mounting direction of a main body on which the display module is mounted; a step of detecting a touch release from the display module; a step of executing a control command of a touch input corresponding to the touch contact and the touch release when the operation operation is not detected; and a step of not executing the control command when the operation operation is detected.

[0015] The step of detecting the above-mentioned operation may include a step of a motion sensor detecting a change in the mounting direction of the main body.

[0016] The step of detecting the above-mentioned manipulation action may include a step of the motion sensor detecting a change in acceleration greater than a reference value.

[0017] The step of detecting the above-mentioned operation may include a step of detecting two or more of the above-mentioned touch contacts in an area adjacent to an edge of the above-mentioned display module or detecting the above-mentioned touch contacts in an area larger than a reference area.

[0018] The display device of the present invention can improve usability by preventing unintended touch input from being recognized by the user.

[0019] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present invention belongs from the description below.

[0033] Meanwhile, the display device (100) described herein is an intelligent display device (100) that adds computer support functions to, for example, a broadcast reception function. While remaining faithful to the broadcast reception function, it can be equipped with an Internet function and other functions, thereby providing a more convenient interface such as a manual input device, touch screen, or space remote control. In addition, it can be connected to the Internet and a computer with support for wired or wireless Internet functions, and can perform functions such as email, web browsing, banking, or games. A standardized, general-purpose operating system (OS) can be used for these various functions.

[0034] Accordingly, the display device (100) described in the present invention can perform various user-friendly functions, for example, since various applications can be freely added or deleted on a general-purpose OS kernel. More specifically, the display device (100) can be, for example, a network TV, HBB TV, smart TV, etc., and in some cases, can also be applied to a smartphone.

[0035] Figure 1 is a block diagram for explaining each configuration of a display device (100).

[0036] The display device (100) may include a communication unit (110), an input unit (120), a sensing unit (140), an output unit (150), a control unit (180), a storage unit (185), and a power supply unit (190). The configuration illustrated in FIG. 1 may include only some of the configurations, or one configuration may perform two functions.

[0037] The communication unit (110) may include a broadcast receiving unit (111) including a tuner unit and a demodulator unit. The tuner unit of the broadcast receiving unit (111) may select a broadcast signal corresponding to a channel selected by a user or all previously stored channels among broadcast signals received through an antenna or cable. The tuner unit may convert the selected broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

[0038] Meanwhile, the tuner unit can sequentially select broadcast signals of all stored broadcast channels through a channel memory function among the received broadcast signals and convert them into intermediate frequency signals or baseband video or audio signals.

[0039] The demodulation unit of the broadcast receiving unit (111) can perform a demodulation operation by receiving a digital IF signal (DIF) converted by the tuner unit. The demodulation unit can output a stream signal (TS) after performing demodulation and channel decoding. At this time, the stream signal can be a signal in which a video signal, an audio signal, or a data signal is multiplexed.

[0040] The stream signal output from the demodulation unit can be input to the control unit (180). The control unit (180) can perform demultiplexing, image / audio signal processing, etc., and then output the image through the display unit (151) and output the audio through the audio output unit (152).

[0041] The external device interface unit (112) can connect an external device and a display device (100) to receive video signals, audio signals, and control signals from the external device. The interface unit (112) can be connected wired or wirelessly to external devices such as a DVD (Digital Versatile Disk), Blu-ray, game device, camera, camcorder, computer (laptop), etc.

[0042] The external device interface unit (112) transmits an image, voice, or data signal input from the outside via a connected external device to the control unit (180) of the display device (100). In addition, the image, voice, or data signal processed by the control unit (180) can be output to the connected external device.

[0043] The external device interface unit (112) may include a wired type and a wireless type. The wired type includes a physical terminal provided in the display device (100), and the wireless type may be connected to an external device through an antenna that receives a wireless signal.

[0044] The wired type may include a USB terminal, a CVBS (Composite Video Banking Sync) terminal, a component terminal, an S-video terminal (analog), a DVI (Digital Visual Interface) terminal, an HDMI (High Definition Multimedia Interface) terminal, an RGB terminal, a D-SUB terminal, etc., so as to input video and audio signals from an external device to the display device (100).

[0045] The wireless type can perform short-range wireless communication with other electronic devices located nearby. The display device (100) can be connected to a network with other electronic devices according to communication standards such as Bluetooth, RFID (Radio Frequency Identification), IrDA (Infrared Data Association), UWB (Ultra Wideband), ZigBee, and DLNA (Digital Living Network Alliance), for example.

[0046] The network interface unit (113) can access a specific web page via the connected network or another network linked to the connected network. In other words, it can access a specific web page via the network and transmit or receive data to or from the corresponding server. Additionally, it can receive content or data provided by a content provider or network operator.

[0047] That is, content such as movies, advertisements, games, VOD, and broadcast signals, as well as related information, can be received from content providers or network providers via the network. Furthermore, firmware update information and update files provided by network operators can be received. Furthermore, data can be transmitted to the Internet, content providers, or network operators.

[0048] In addition, the network interface unit (113) can select and receive a desired application from among applications open to the public through the network.

[0049] According to an embodiment, the network interface unit (113) may transmit or receive predetermined data with a user terminal connected to the display device through a network when a game application is executed on the display device. In addition, the network interface unit (113) may transmit or receive predetermined data with a server that stores game scores.

[0050] The input unit (120) may include a microphone (121) that collects sound, a user input unit (123) that detects a user's command, and a remote signal receiving unit (125) that receives a signal from a remote control device (127).

[0051] The microphone (121) can recognize the user's voice or surrounding sounds, and in particular, receives the user's voice and processes it into electrical voice data. The microphone (121) can be implemented with various noise removal algorithms to remove noise generated during the process of receiving external audio signals.

[0052] The microphone (121) can not only collect the user's voice, convert it into voice data, and store it in the storage unit (185) or transmit it to an external device through the communication unit (110), but can also function as a user input unit (123) by analyzing the voice data and recognizing it as a user command.

[0053] The microphone (121) can be mounted on a remote control device (127) to be described later in addition to the main body of the display device (100) and transmitted to the control unit (180) through the remote signal receiving unit (125).

[0054] The user input unit (123) is a device through which a user inputs control commands to control the display device. The user input unit (123) may be configured as a keypad, button, touch pad, or touch screen.

[0055] If the user input unit (123) has a hard key button, the user can input a command related to the display device (100) by pushing the hard key button. If the user input unit (123) has a touch screen, the user can input a command related to the display device (100) using the remote control device (127) by touching the soft key of the touch screen.

[0056] In addition, the user input unit (123) may be equipped with various types of input means that can be operated by the user, such as a scroll key or a jog key, and this embodiment does not limit the scope of the present invention.

[0057] Recently, as the size of the bezel of the display device (100) has become smaller, the number of display devices (100) with a minimized user input unit (123) in the form of a physical button exposed to the outside has increased. Instead, a minimum of physical buttons are located on the back or side, and user input can be received through a remote control device (127) via a touchpad or a remote signal receiving unit (125) described later.

[0058] The remote signal receiving unit (125) can input commands related to the display device (100) through a remote control device (127) having a user input unit (123). The remote signal receiving unit (125) is a user input unit (123) and receives signals from the remote control device (127) according to various communication methods such as RF (Radio Frequency) communication method and infrared (IR) communication method, and thus may belong to a wireless communication unit.

[0059] The sensing unit (140) refers to a device that detects changes within the display device (100) or external changes. For example, it may include an optical sensor (141) that utilizes light, such as a proximity sensor, an illumination sensor, or an infrared sensor (IR sensor). A camera can also be considered a type of optical sensor, and thus the display device can be controlled based on information collected by the camera.

[0060] The touch sensor (143) is located on the front of the display unit and can detect touch input. The touch sensor can be viewed as a type of user input unit (123) in that it receives user control commands.

[0061] Recently, display devices (100) that can move or change the direction of the display part have appeared, and thus, a motion sensor (145) including a gyro sensor, an acceleration sensor, etc. may be provided to detect the attitude of the display device.

[0062] In addition, it may include at least one of an ultrasonic sensor, a voice sensor (e.g., a microphone), a battery gauge, and an environmental sensor (e.g., a hygrometer, a thermometer, etc.).

[0063] Based on the information collected from the sensing unit (140), the control unit (180) can check the status of the display device (100) and, if a problem occurs, notify the user of it or control it to maintain the best condition by adjusting it on its own.

[0064] In addition, the content, picture quality, size, etc. of the image provided to the display unit (151) can be controlled differently depending on the viewer detected by the sensing unit (124) or the surrounding lighting, etc., to provide an optimal viewing environment. As smart TVs advance, the functions installed in the display device are increasing, and the sensing unit (140) is also increasing along with it.

[0065] The output unit (150) is a device that provides visual and auditory information to the user through the display device (100), and may include a display unit (151) and an audio output unit (152).

[0066] The display unit (151) can generate a driving signal by converting a video signal, data signal, OSD signal, control signal, etc. processed by the control unit (180) or a video signal, data signal, control signal, etc. received from the interface unit. The display unit (151) can include a display panel having a plurality of pixels.

[0067] The plurality of pixels provided on the display panel may have RGB sub-pixels. Alternatively, the plurality of pixels provided on the display panel may have RGBW sub-pixels. The display unit (151) may convert image signals, data signals, OSD signals, control signals, etc. processed by the control unit (180) to generate driving signals for the plurality of pixels.

[0068] The display unit (151) can be a PDP (Plasma Display Panel), an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode), a flexible display, etc., and may also be a 3D display. The 3D display unit (151) can be divided into a glasses-free type and a glasses type.

[0069] The display device (100) includes a display unit (151) that occupies most of the front surface area and a case that covers the rear side of the display unit (151) and packages the display unit (151).

[0070] Recently, display devices (100) can utilize a display unit (151) that can be bent, such as LEDs (Light Emitting Diodes) or OLEDs (Organic Light Emitting Diodes), to implement a curved screen rather than a flat screen.

[0071] Previously, LCDs were primarily used because they were unable to emit light on their own, so they relied on backlight units for light. Backlight units are devices that evenly distribute light from a light source to the liquid crystal display (LCD) located at the front. As backlight units have become thinner, thinner LCDs have become possible. However, it has been difficult to implement backlight units using flexible materials, and when the backlight unit is bent, it becomes difficult to supply light evenly to the LCD, causing screen brightness to fluctuate.

[0072] On the other hand, in the case of LEDs or OLEDs, since each element forming a pixel emits light on its own, it is possible to implement a curved display without using a backlight unit. In addition, since each element emits light on its own, even if the positional relationship with neighboring elements changes, its own brightness is not affected, so a curved display unit (150) can be implemented using LEDs or OLEDs.

[0073] OLED (Organic Light-Emitting Diodes) panels made their debut in the mid-2010s and are rapidly replacing LCDs in the small and medium-sized display market. OLEDs utilize the self-luminous phenomenon, where fluorescent organic compounds emit light when current flows through them. OLEDs offer faster image quality response times than LCDs, resulting in virtually no afterimages when displaying video.

[0074] OLED uses three types of fluorescent organic compounds with self-luminous functions: red, green, and blue. It is a light-emitting display product that utilizes the phenomenon in which electrons injected from the cathode and anode and positively charged particles combine within the organic material to emit light on their own, so there is no need for a backlight (backlight device) that reduces color.

[0075] The LED (Light Emitting Diode) panel is a technology that uses one LED element as one pixel, and since the size of the LED element can be reduced compared to the past, a flexible display unit (151) can be implemented. Devices previously called LED TVs used LEDs as a light source for a backlight unit that supplied light to an LCD, and the LEDs themselves did not form a screen.

[0076] The display unit may include a plurality of pixels (R, G, B). The plurality of pixels (R, G, B) may be formed in each area where a plurality of data lines and a plurality of gate lines intersect. The plurality of pixels (R, G, B) may be arranged or arranged in a matrix form.

[0077] For example, a plurality of pixels (R, G, B) may include a red (Red, hereinafter referred to as 'R') sub-pixel, a green (Green, 'G') sub-pixel, and a blue (Blue, 'B') sub-pixel. The plurality of pixels (R, G, B) may further include a white (White, hereinafter referred to as 'W') sub-pixel.

[0078] The side of the display unit (151) that displays an image may be referred to as the front or front. When the display unit (151) displays an image, the side from which the image cannot be observed may be referred to as the rear or back. Meanwhile, the display unit (151) is configured as a touch screen and can be used as an input device in addition to an output device.

[0079] The audio output unit (152) receives a signal processed by the control unit (180) and outputs it as voice.

[0080] The control unit (180) may include at least one processor, and may control the overall operation of the display device (100) using the processor included therein. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an ASIC or another hardware-based processor.

[0081] The control unit (180) can demultiplex a stream input through a tuner unit, a demodulator unit, an external device interface unit (112), or a network interface unit (113), or process demultiplexed signals to generate and output a signal for video or audio output.

[0082] The image signal processed by the control unit (180) can be input to the display unit (151) and displayed as an image corresponding to the image signal. In addition, the image signal processed by the control unit (180) can also be input to an external output device through the external device interface unit (112).

[0083] The voice signal processed by the control unit (180) can be output as audio to the audio output unit (152). In addition, the voice signal processed by the control unit (180) can be input to an external output device through the external device interface unit (112). Although not shown in FIG. 2, the control unit (180) may include a demultiplexing unit, an image processing unit, etc. This will be described later with reference to FIG. 3.

[0084] In addition, the control unit (180) can control the overall operation within the display device (100). For example, the control unit (180) can control the tuner unit (111) to select (tune) a broadcast corresponding to a channel selected by the user or a previously stored channel.

[0085] In addition, the control unit (180) can control the display device (100) by a user command or an internal program input through the user input interface unit (173). Meanwhile, the control unit (180) can control the display unit (151) to display an image. At this time, the image displayed on the display unit (151) may be a still image or a moving image, and may be a 2D image or a 3D image.

[0086] Meanwhile, the control unit (180) can cause a predetermined 2D object to be displayed within an image displayed on the display unit (151). For example, the object can be at least one of a connected web screen (newspaper, magazine, etc.), EPG (Electronic Program Guide), various menus, widgets, icons, still images, videos, and text.

[0087] Meanwhile, the control unit (180) may modulate and / or demodulate a signal using the Amplitude Shift Keying (ASK) method. Here, the Amplitude Shift Keying (ASK) method may mean a method of modulating a signal by varying the amplitude of a carrier wave according to a data value, or of restoring an analog signal to a digital data value according to the amplitude of the carrier wave.

[0088] For example, the control unit (180) can modulate a video signal using the amplitude shift keying (ASK) method and transmit it through a wireless communication module.

[0089] For example, the control unit (180) can demodulate and process an image signal received through a wireless communication module using the amplitude shift keying (ASK) method.

[0090] Through this, the display device (100) can easily transmit and receive signals with other adjacently placed video display devices without using a unique identifier such as a MAC address (Media Access Control Address) or a complex communication protocol such as TCP / IP.

[0091] Meanwhile, the display device (100) may further include a camera unit. The camera unit can capture images of the user. The camera unit may be implemented with a single camera, but is not limited thereto, and may also be implemented with multiple cameras. Meanwhile, the camera unit may be embedded in the display device (100) above the display unit (151) or may be separately positioned. Image information captured by the camera unit may be input to the control unit (180).

[0092] The control unit (180) can recognize the user's location based on the image captured by the camera unit. For example, the control unit (180) can determine the distance (z-axis coordinate) between the user and the display device (100). In addition, the control unit (180) can determine the x-axis coordinate and y-axis coordinate within the display unit (151) corresponding to the user's location.

[0093] The control unit (180) can detect the user's gesture based on the image captured from the shooting unit, or the signal detected from the sensing unit (140), or a combination thereof.

[0094] The storage unit (185) may store programs for each signal processing and control within the control unit (180), or may store signal-processed video, audio, or data signals. For example, the storage unit (185) may store application programs designed for the purpose of performing various tasks that can be processed by the control unit (180), and may selectively provide some of the stored application programs upon request from the control unit (180).

[0095] Programs stored in the storage unit (185) are not particularly limited as long as they can be executed by the control unit (180). The storage unit (185) may also perform a function for temporarily storing video, audio, or data signals received from an external device through the external device interface unit (112). The storage unit (185) may store information regarding a specific broadcast channel through a channel memory function such as a channel map.

[0096] Although the storage unit (185) of FIG. 1 is illustrated as being provided separately from the control unit (180), the scope of the present invention is not limited thereto, and the storage unit (185) may be included within the control unit (180).

[0097] The storage unit (185) may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) or non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

[0098] The power supply unit (190) can supply power to the entire display device (100). In particular, it can supply power to a control unit (180) that can be implemented in the form of a system on chip (SOC), a display unit (151) for displaying images, and an audio output unit (152) for outputting audio.

[0099] Specifically, the power supply unit (190) may be equipped with a converter (not shown) that converts AC power into DC power and a Dc / Dc converter (not shown) that converts the level of DC power.

[0100] Meanwhile, the power supply unit (190) receives power from an external source and distributes power to each component. The power supply unit (190) may utilize a method of supplying AC power by directly connecting to an external power source, or may include a power supply unit (190) that can be recharged and used, including a battery.

[0101] The former requires a wired cable connection, making movement difficult or limited. The latter offers freedom of movement, but increases weight and volume by the battery. Charging requires a direct connection to a power cable or a charging cradle (not shown) for a set period of time.

[0102] The charging cradle can be connected to the display device through an externally exposed terminal, or the built-in battery can be charged when the device is brought into proximity using a wireless method.

[0103] Meanwhile, the block diagram of the display device (100) illustrated in FIG. 1 is only a block diagram for one embodiment of the present invention, and each component of the block diagram may be integrated, added, or omitted depending on the specifications of the display device (100) actually implemented.

[0104] That is, two or more components may be combined into a single component, or a single component may be subdivided into two or more components, as needed. Furthermore, the functions performed by each block are intended to illustrate embodiments of the present invention, and their specific operations or devices do not limit the scope of the present invention.

[0105] Fig. 2 is a front perspective view illustrating a display device (100) in a mounted state according to one embodiment of the present invention, and Fig. 3 is a front perspective view illustrating a horizontal mounted state of the display device (100) according to one embodiment of the present invention. Fig. 4 is a rear perspective view illustrating a state in which the stand (160) of the display device (100) of the present invention is folded and configured as a case.

[0106] The display device (100) includes a display unit (151) that outputs an image on the front, and may include a main body (10) in the shape of a rectangular parallelepiped with a predetermined thickness and a stand (160) that supports the main body (10).

[0107] The main body (10) may be equipped with a control unit (180) that drives a display unit (151), an audio output unit (152) that outputs sound, and a power supply unit (19) that supplies power to the display unit (151) and the control unit. It may also include an interface unit that receives external power or connects a cable for transmitting and receiving data.

[0108] The stand (160) of the embodiment illustrated in FIGS. 2 to 4 can be used as a stand as in FIGS. 2 and 3 when the display device (100) is in use, and can be used as a case to protect the main body (10) as in FIG. 4 when the display device (100) is not in use and is stored or moved.

[0109] The stand (160) may include a rear cover (161) fixed to the back of the main body (10) and a folio cover (162) that can selectively cover or open the display portion (151) on the front. The folio cover (162) spaced from the front of the display portion (151) can be folded into multiple stages and connected to the rear cover (161) to be converted into a stand (160) that supports the main body (10).

[0110] The display device (100) of the present invention can be rotated so that the longitudinal direction of the main body (10) is placed upright as in FIG. 2 using a stand (160) so that the longitudinal direction is arranged horizontally as in FIG. 3.

[0111] The display device (100) of the present invention can change the orientation of the main body (10) from the state of FIG. 2 to the state of FIG. 3 or vice versa by the user turning the orientation of the main body (10) with his / her hand (H). At this time, the stand (160) remains fixed to the mounting surface, and only the orientation of the main body (10) can be changed.

[0112] The stand (160) of the present embodiment may include a rotation module (165) that is connected to the back surface of the main body (10) by penetrating the rear cover (161) that is connected to the back surface of the main body (10) for rotation of the main body (10).

[0113] The stand (160) of the present invention is not limited to the display device (100) shown in FIGS. 2 and 3, and includes all stands (160) that can be manually rotated by a user in a mounted state.

[0114] Depending on the shape of the stand (160), as shown in FIGS. 2 and 3, the main body (10) may be placed at a predetermined angle from the mounting surface or may be placed vertically, and all of these may be included in the shape of the display device (100) of the present invention.

[0115] The main body (10) of the display device (100) of the present invention is characterized by being rotatably coupled to a stand (160), and can be connected via a rotation module (165) so that a user can hold the main body (10) and rotate it clockwise or counterclockwise.

[0116] The rotation module (165) can rotate around an axis perpendicular to the surface of the display unit (151). The main body (10) can rotate with respect to the stand (160) via the rotation module (165), and can be placed in either a vertical mounting state as in Fig. 2 or a horizontal mounting state as in Fig. 3.

[0117] The rotation module (165) may include a stopper that fixes it so that it is stably fixed in both vertical and horizontal mounting states. In this case, the user must apply a certain amount of force to the main body (10) to rotate it. In particular, the display device (100) of the present invention may include a large display unit (151) of 20 inches or more. Since the size of the main body (10) is large, a large force must be applied when changing the direction of the main body (10), and the user can rotate the main body (10) by holding the main body (10) with both hands (H).

[0118] FIG. 5 is a diagram illustrating a rotation process of a display device (100) according to one embodiment of the present invention. FIG. 5 (a) is a horizontal mounting state of FIG. 3, FIG. 5 (c) is a vertical mounting state of FIG. 2, and FIG. 5 (b) is a diagram illustrating a process of switching from a horizontal mounting state to a vertical mounting state.

[0119] As described above, the display device (100) of the present invention can be rotated by holding one end of the display device (100) to change the direction of the main body (10). At this time, as illustrated in FIG. 4, the main body (10) can be rotated using both hands (H).

[0120] When holding the main body (10) with both hands (H) and rotating it, the user's hand (H) may touch the end of the display unit (151) as shown in (a) of Fig. 5. In recent display devices (100), the size of the bezel located around the display unit (151) has become smaller, making it difficult to avoid the user's hand (H) touching it.

[0121] At this time, if a command button is located at a location where the user's hand (H) touches, or a specific user command touch gesture is recognized, an unintended function may be executed or the screen may be switched. As illustrated in Fig. 5, when the main body (10) is rotated, the screen may be switched in the state (c) of Fig. 5 when the user touches an area corresponding to the weather application on the screen and rotation is completed.

[0122] In order to resolve the above inconvenience, the present invention is characterized in that when a user detects a motion for the purpose of changing the direction of the main body (10), the touch input is ignored and a command corresponding to the input is not executed.

[0123] Figure 6 is a flowchart illustrating one embodiment of a control method of a display device (100) of the present invention. Touch input is comprised of a touch contact in which a user's finger (or a conductive member such as a touch pen) touches the display unit (151) and a touch release in which the finger in contact with the display unit (151) moves away.

[0124] If the control unit (180) recognizes a user's operation to rotate the main body (10) between the recognition of touch contact (S110) and the recognition of touch release (S150, S170), it does not execute a command corresponding to the touch input when the touch is released. At this time, a method for recognizing the operation can utilize a motion sensor (145) mounted on the main body (10). The motion sensor (145) may include a gyro sensor that detects the posture of the main body (10) by measuring angular velocity and an acceleration sensor that detects the movement of the main body (10) by detecting acceleration.

[0125] When a user rotates the main body (10) to change the mounting direction of the main body (10), the angular velocity and acceleration of the main body (10) change. If the amount of change detected by the motion sensor (145) is greater than a reference value, the control unit (180) can recognize that the user is rotating the main body (10) and determine that there is an operation (S120).

[0126] The value measured here may be the angular velocity detected by the gyro sensor or the acceleration detected by the acceleration sensor, and by measuring both values, if both sensors exceed the reference value or at least one of the two sensors exceeds the reference value, it can be determined that there is an operation.

[0127] If the motion sensor (145) detects a change greater than the reference value, the touch coordinate value is not executed even if the touch release is recognized (S160). However, if a change greater than the reference value is not detected, it is determined that there is no manipulation and if the touch release is recognized (S170), the touch coordinate value is executed (S180).

[0128] Fig. 7 is a flowchart illustrating another embodiment of a control method for a display device (100) of the present invention. In this embodiment, the presence or absence of an operation can be determined based on the detected location and number of touch inputs. When a user holds the main body (10) with both hands (H), the part that comes into contact with the display unit (151) can correspond to the edge area (1515) of the display device (100), and touch inputs can be recognized in two different areas.

[0129] The control unit (180) determines that the user holds the main body (10) with both hands (H) to rotate the main body (10) when the detected touch contact is an edge area (1515) (S220) and the touch input of the edge area (1515) is a multi-touch detected in two areas (S230), and thus determines that there is an operation. In this case, the control unit (180) does not execute a command corresponding to the touch coordinate value when the touch release is recognized (S250) (S260).

[0130] However, if the touch contact coordinates are not in the edge area (1515) or are not a multi-touch wall, the control unit (180) determines that there is no manipulation (S220, S230), and can execute a command corresponding to the touch coordinate value when the touch is released (S270, S280).

[0131] Figure 8 is a flowchart illustrating another embodiment of a control method for a display device (100) of the present invention. This embodiment can determine the presence or absence of an operation based on the detected location and area of ​​a touch input. When a user holds the main body (10) with both hands (H), the part that comes into contact with the display may correspond to the edge area (1515) of the display device (100).

[0132] In addition, when a user holds the main body (10) with a hand (H), the user's palm touches the display unit (151). The area of ​​the touch contact by the palm is different from that of the touch contact using a finger or a touch pen. If the area of ​​the touch contact is greater than the reference area, the control unit (180) can determine that there is an operation because the user is holding the main body (10) to rotate the main body (10).

[0133] The control unit (180) does not execute a command corresponding to the touch coordinate value when a touch contact is recognized in the edge area (1515) (S320), the touch area is greater than or equal to the reference area (S330), and when a touch release is recognized (S350), the control unit (180) does not execute a command corresponding to the touch coordinate value (S360). However, when the touch contact coordinate is not in the edge area (1515) or is less than or equal to the reference area, the control unit (180) determines that there is no manipulation operation, and can execute a command corresponding to the touch coordinate value when a touch release is recognized (S380).

[0134] While typical touch inputs typically have a short time between touch contact and touch release, they can persist for a certain amount of time if accompanied by rotational motion of the main body. Although not shown in the flowchart, the control unit can determine that an operation has occurred if the time between touch contact and touch release exceeds a reference time.

[0135] In FIGS. 7 and 8, the manipulation operation is determined based on the area and location of the touch input, but the presence or absence of the manipulation operation can be determined by applying conditions such as the value sensed by the motion sensor (145) of FIG. 6 or the time interval between the touch contact and release described above. That is, the control unit (180) can determine the presence or absence of the manipulation operation in which the user holds the main body (10) with the hand (H) to rotate the main body (10) by considering one or more of the methods of FIGS. 6 to 8.

[0136] As discussed above, the display device (100) can improve usability by preventing unintended touch input from being recognized by the user.

[0137] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
