Description

Technical Field

[0001] This disclosure relates to a display device. Background Technology

[0002] Recently, the functions of terminals have become increasingly diversified. For example, they can perform data and voice communication, take photos and videos with a camera, record audio, play music files through a speaker system, and output images or videos to a display.

[0003] Some terminals have added video game functionality or perform multimedia playback functions.

[0004] As the functions of terminals become more diverse, terminals are implemented in the form of multimedia devices (multimedia players) equipped with complex functions such as capturing still or moving images, reproducing music or video files, playing games, and receiving broadcasts.

[0005] When the display size of a terminal is larger than a certain inch (e.g., 27 inches), it becomes difficult for the user to touch the display.

[0006] In other words, in display devices larger than a certain size, more finger movement is required to perform the same operations as touch operations on display devices of the same size as traditional flat panels, which causes inconvenience to users. Summary of the Invention

[0007] This disclosure provides a display device that optimizes usability by changing display properties according to the type of user input to the display device.

[0055] The display device 100 can play back content files (moving image files, still image files, music files, document files, application files, etc.) stored in the memory 140 and provide them to the user.

[0056] User input interface 150 can send user-input signals to controller 170 or send signals from controller 170 to the user. For example, user input interface 150 can receive and process control signals such as power on / off, channel selection, and screen settings from remote control device 200 according to various communication methods such as Bluetooth, WB (Ultra-Wideband), ZigBee, RF (Radio Frequency), or Infrared (IR) communication methods, or can perform processing to send control signals from controller 170 to remote control device 200.

[0057] Additionally, the user input interface 150 can send control signals input from local keys such as the power button, channel button, volume button, and setting value (not shown) to the controller 170.

[0058] The image signal processed by the controller 170 can be input to the display 180 and displayed as an image corresponding to the corresponding image signal. In addition, the image signal processed by the controller 170 can be input to an external output device through the external device interface 135.

[0059] The audio signal processed by the controller 170 can be output to the speaker 185. In addition, the audio signal processed by the controller 170 can be input to an external output device through the external device interface 135.

[0060] In addition, the controller 170 can control the overall operation of the display device 100.

[0061] Additionally, the controller 170 can control the display device 100 based on user commands or internal programs input through the user input interface 150 and connect to the network to download applications, application lists, or user-desired applications to the display device 100.

[0062] The controller 170 allows the user to select channel information, along with processed image or audio signals, and output them through the display 180 or speaker 185.

[0063] Additionally, the controller 170 can output image or audio signals via the display 180 or speaker 185 according to a command to play back an image from an external device via the user input interface 150. The image or audio signals are input from an external device (e.g., a camera or camcorder) via the external device interface 135.

[0064] Furthermore, the controller 170 may allow the display 180 to display images, such as broadcast images input via the tuner 131, externally input images input via the external device interface 135, images input via the network interface unit, or images stored in the memory 140. In this case, the image displayed on the display 180 may be a still image or a moving image, and may be a 2D image or a 3D image.

Therefore, the user of the wearable device can use the data processed by the display device 100 through the wearable device.

[0069] The display 180 can convert the image signals, data signals, and OSD signals processed by the controller 170 or the image signals or data signals received from the external device interface 135 into R, G, and B signals, and generate drive signals.

[0070] In addition, due to Figure 1 The display device 100 shown is only an embodiment of this disclosure, so some of the components shown may be integrated, added or omitted depending on the specifications of the actual display device 100.

[0071] That is, if necessary, two or more components can be combined into one component, or one component can be divided into two or more components. Furthermore, the functions performed in each block are for describing embodiments of this disclosure, and their specific operations or apparatus do not limit the scope of this disclosure.

[0072] According to another embodiment of this disclosure, with Figure 1 The display device 100 shown is different. The display device 100 can receive images via network interface 133 or external device interface 135 without tuner 131 and demodulator 132, and play back images.

[0073] For example, the display device 100 may be divided into an image processing device (e.g., a set-top box) that receives broadcast signals or content according to various network services and a content playback device that plays back content input from the image processing device.

[0074] In this case, the operation method of the display device according to the embodiments of the present disclosure, which will be described below, can be used not only by referring to Figure 1 The described display device 100 is implemented and can be implemented by one of an image processing device such as a separate set-top box and a content playback device including a display 180 and / or a speaker 185.

[0093] Will refer again Figure 2 Provide a description.

[0094] When the user input interface 230 includes a touch screen, the user can input commands related to the display device 100 to the remote control device 200 by touching the soft keys on the touch screen. Additionally, the user input interface 230 may include various types of input methods operable by the user, such as scroll keys or tap keys; this embodiment does not limit the scope of this disclosure.

[0095] Sensor 240 may include gyroscope sensor 241 or accelerometer sensor 243, wherein gyroscope sensor 241 can sense information about the movement of remote control device 200.

[0096] For example, the gyroscope sensor 241 can sense information about the operation of the remote control device 200 based on the x, y, and z axes, and the accelerometer sensor 243 can sense information about the moving speed of the remote control device 200. Furthermore, the remote control device 200 may also include a distance measurement sensor to sense the distance between the display device 100 and the display 180.

[0097] The output interface 250 can output image or audio signals corresponding to the operation of the user input interface 230 or signals sent from the display device 100.

[0098] Users can use the output interface 250 to identify whether the user input interface 230 is being operated or whether the display device 100 is being controlled.

[0099] For example, when the user input interface 230 is operated or sends signals to and receives signals from the display device 100 via the wireless communication unit 225, the output interface 450 may include an LED 251 that emits light, a vibrator 253 that generates vibrations, a speaker 255 that outputs sound, or a display 257 that outputs images.

[0100] In addition, the power supply circuit 260 can supply power to the remote control device 200, and stop supplying power when the remote control device 200 has not moved for a predetermined time, so as to reduce power consumption.

[0101] When a preset key in the remote control device 200 is activated, the power supply circuit 260 can be restarted.

[0102] The memory 270 can store various types of programs and application data required for the control or operation of the remote control device 200.

[0103] When the remote control device 200 wirelessly transmits and receives signals through the display device 100 and the RF circuit 221, the remote control device 200 and the display device 100 transmit and receive signals through a predetermined frequency band.

[0104] The controller 280 of the remote control device 200 can store and reference information in the memory 270 about the frequency bands that enable it to wirelessly send signals to and receive signals from the display device 100 paired with the remote control device 200.

[0105] The controller 280 can control all matters related to the control of the remote control device 200. The controller 280 can send signals corresponding to predetermined key operations of the user input interface 230 or signals corresponding to the movement of the remote control device 200 sensed by the sensor 240 via the wireless communication unit 225.

[0106] Additionally, the microphone 290 of the remote control device 200 can receive speech.

[0107] Multiple microphones 290 are available.

[0108] Next, we will refer to Figure 4 Provide a description.

[0109] Figure 4 An example of using a remote control device according to an embodiment of the present disclosure is shown.

[0110] exist Figure 4 In the image, (a) shows a pointer 205 corresponding to the remote control device 200 displayed on the display 180.

[0111] The user can move or rotate the remote control device 200 in all directions. The pointer 205 displayed on the monitor 180 of the display device 100 corresponds to the movement of the remote control device 200. As shown in the figure, the pointer 205 moves and is displayed in 3D space according to the movement of the remote control device 200, therefore the remote control device 200 can be called a spatial remote control device.

[0112] exist Figure 4 In (b), it is shown that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the display 180 of the display device 100 moves to the left accordingly.

[0113] Information regarding the movement of the remote control device 200, detected by its sensors, is sent to the display device 100. The display device 100 can calculate the coordinates of the pointer 205 based on the information regarding the movement of the remote control device 200. The display device 100 can then display the pointer 205 in accordance with the calculated coordinates.

[0114] exist Figure 4 In (c), it is shown that the user moves the remote control device 200 away from the display 180 while pressing a specific button on the remote control device 200. As a result, the selected area on the display 180 corresponding to the pointer 205 can be zoomed in and magnified.

[0115] Conversely, when the user moves the remote control device 200 closer to the display 180, the selected area on the display 180 corresponding to the pointer 205 can be zoomed out and reduced in size.

[0116] On the other hand, when the remote control device 200 moves away from the display 180, the selected area can be pulled further away, and when the remote control device 200 moves closer to the display 180, the selected area can be pulled closer.

[0117] Furthermore, when a specific button in the remote control device 200 is pressed, the recognition of up, down, left, or right movement can be excluded. That is, when the remote control device 200 moves away from or closer to the display 180, up, down, left, or right movement is not recognized; only forward and backward movement is recognized. When the specific button in the remote control device 200 is not pressed, only the pointer 205 moves according to the up, down, left, or right movement of the remote control device 200.

[0118] Furthermore, the moving speed or direction of the pointer 205 can correspond to the moving speed or direction of the remote control device 200.

[0119] Furthermore, in this specification, a pointer refers to an object displayed on the display 180 in response to an operation of the remote control device 200. Therefore, objects of various shapes other than the arrow shape shown in the figure can serve as pointer 205. For example, objects can include concepts such as points, cursors, prompts, and rough outlines. In addition, pointer 205 can be displayed corresponding to any one of the points on the horizontal and vertical axes of the display 180, and can also be displayed corresponding to multiple points such as lines and surfaces.

[0120] Figure 5A and Figure 5B This is a diagram used to describe the horizontal and vertical modes of a vertical display device according to embodiments of the present disclosure.

[0121] Reference Figure 5A and Figure 5B The vertical display device 100 is shown.

[0122] The shaft 103 and the bracket base 105 can be connected to the display device 100.

[0123] Axis 103 can connect the display device 100 and the support base 105 to each other. Axis 103 can extend vertically.

[0124] The lower end of shaft 103 can be connected to the edge of bracket base 105.

[0125] The lower end of shaft 103 can be rotatably connected to the edge of bracket base 105.

[0126] The display device 100 and the shaft 103 can rotate about a vertical axis relative to the support base 105.

[0127] The upper part of shaft 103 can be connected to the rear surface of display device 100.

[0128] The stand base 105 can be used to support the display device 100.

[0129] The display device 100 can be configured to include an axis 103 and a support base 105.

[0130] The display device 100 can rotate about the point where the upper part of the axis 103 contacts the rear surface of the display 180.

[0131] Figure 5A The display 180 is shown operating in a landscape mode where the horizontal length is greater than the vertical length. Figure 5B The display 180 is shown operating in a portrait mode where the vertical length is greater than the horizontal length.

[0132] Users can move the vertical display device while holding it. That is, unlike fixed devices, the improved mobility of the vertical display device allows users to be free from placement restrictions.

[0133] Figure 6 This is a flowchart describing an operation method of a display device according to an embodiment of the present disclosure.

[0134] Reference Figure 6 The controller 170 of the display device 100 can receive user input (S601).

[0135] In this implementation, the user input can be any one of control input, touch input, and mouse input received from the remote control device 200.

[0136] The controller 170 can receive user input while displaying an image on the display 180, and determine the type of user input received.

[0137] The controller 170 of the display device 100 can obtain the type of the received user input (S603).

[0138] The controller 170 can determine the type of user input based on the path through which the user input is received.

[0139] The user input type can be any of the following: remote control input, touch input, or mouse input.

[0140] In one implementation, when user input is received through user input interface 150, controller 170 can determine the type of user input as remote control input type.

[0141] When user input is received via display 180, controller 170 can determine the type of user input as touch input.

[0142] When user input is received via external device interface 135, controller 170 can determine the type of user input as mouse input. The mouse can be connected to a USB port provided in external device interface 135.

[0143] The controller 170 of the display device 100 can change the display properties according to the type of user input obtained (S605).

[0144] In an implementation, display properties may include one or more of the size, brightness, and position of the image displayed on the display 180.

[0145] In another embodiment, display properties may include one or more of the size, brightness, and position of graphical user interface (GUI) elements displayed on the display 180.

[0146] In another implementation, changing the display properties can indicate a change in the display mode.

[0147] In this implementation, mouse input can be handled in a similar manner to touch input. This is because the distance between the display device 100 and the user can be relatively close in both mouse and touch input scenarios.

[0148] The controller 170 of the display device 100 can output a screen with changed display properties through the display 180 (S607).

[0149] When the first display property changes to the second display property based on the type of user input, the controller 170 can reflect the changed property to display an image or GUI.

[0150] This will be described in detail with reference to the following example.

[0151] Figure 7 This is a flowchart illustrating an example of how the properties of a virtual keyboard change based on the type of user input.

[0152] Figure 7 The implementation method can be illustrated in detail in steps S603 to S607.

[0153] Reference Figure 7 The controller 170 can determine whether the user input type is a remote control input type (S701).

[0154] When it is determined that the user input type is a remote control input type, the controller 170 can display a first virtual keyboard with a first property on the display 180 (S703).

[0155] When it is determined that the user input type is touch input type (S705), the controller 170 can display a second virtual keyboard with a second property on the display 180 (S707).

[0156] In this implementation, the size of the first virtual keyboard may be larger than the size of the second virtual keyboard. That is, this property indicates the size of the virtual keyboard.

[0157] When a user controls the operation of the display device 100 via the remote control device 200 and then controls the operation of the display device 100 via touch input, the distance between the user and the display device 100 can become closer.

[0158] In this situation, when the size of the virtual keyboard displayed during control via remote control device 200 remains unchanged, there is an increased inconvenience to the user's hand movements.

[0159] Therefore, according to an embodiment of this disclosure, when the user input type changes from remote control input type to touch input type, the controller 170 can reduce the size of the virtual keyboard.

[0160] Figure 8A This is an illustration used to describe an example of displaying a first virtual keyboard when remote control input is received, according to an embodiment of the present disclosure. Figure 8B This is an illustration used to describe an example of displaying a second virtual keyboard when touch input is received, according to an embodiment of the present disclosure. Figure 8C It is a diagram used to describe the process of applying input to a first virtual keyboard via touch input according to the prior art.

[0161] Reference Figure 8A The display device 100 can display a screen 800 including a search window 810 on the monitor 180.

[0162] The monitor 180 can be any size, such as 27 inches, 29 inches, or 31 inches, but this is just an example.

[0163] The user can control the movement of the pointer 205 (also called the cursor), which is controlled by the movement of the remote control device 200 (also called the remote control).

[0164] When pointer 205 is on search window 810 and a text input command is received from remote control device 200, display device 100 may display a first virtual keyboard 820 with a first size on display 180.

[0165] Reference Figure 8B This illustrates an example of a user touching the search window 810. When touch input is received through the search window 810, the display device 100 may display a second virtual keyboard 830 with a second size smaller than the first size on the display 180.

[0166] That is, when it is determined that the user input type is touch input, the display device 100 can change the first virtual keyboard 820 to the second virtual keyboard 830.

[0167] Users can more easily apply touch input using a smaller virtual keyboard.

[0168] Reference Figure 8C According to the prior art, even if the first virtual keyboard 820 is displayed when touch input is applied, the first virtual keyboard 820 is too large for general users, so the user's hand movement will be significantly increased.

[0169] This makes touch input inconvenient for users.

[0170] When the user input type is changed back to the remote control input type, the display device 100 can... Figure 8A The image shows a first virtual keyboard 820 with a first size.

[0171] That is, the fact that the user is using the remote control device 200 indicates an increase in the distance between the display device 100 and the user. In this case, it is easier for the user to input text via the pointer 205 when the virtual keyboard is larger.

[0172] As described above, according to embodiments of the present disclosure, the display device 100 may be provided with a virtual keyboard of appropriate size according to the type of user input, thereby greatly improving the convenience of input.

[0173] Furthermore, according to another embodiment of this disclosure, when it is determined that the user input type is touch input, not only the size of the virtual keyboard but also the size of the displayed screen can be reduced.

[0174] Figure 8D This is a diagram illustrating the process of reducing the size of a screen when touch input is received on a display, according to an embodiment of the present disclosure.

[0175] exist Figure 8A In the current screen state, the display device 100 can receive touch input at a specific point.

[0176] The display device 100 can be as follows Figure 8D The image shows the size of screen 800 being changed to a smaller screen 801. Therefore, as shown... Figure 8D As shown, the first virtual keyboard 820 can be scaled down to match the scale of the scaled-down screen 801.

[0177] That is, the minimized screen 801 and the minimized virtual keyboard 821 can be displayed around the touch point 840.

[0178] Reducing the screen size by 801 allows it to correspond to the size of a tablet PC.

[0179] The controller 170 of the display device 100 can convert the coordinate system of the existing screen 800 to the coordinate system of the scaled-down screen 801 based on the scaling ratio and the touch point 840.

[0180] That is, the controller 170 can perform a coordinate system transformation, so that the size of the screen 800 is reduced relative to the touch point 840.

[0181] As described above, according to the embodiments of this disclosure, the screen is reduced in size relative to the touch input point, thus optimizing the user's touch experience.

[0182] Furthermore, when a point other than the zoomed-out screen 801 is selected, the display device 100 can switch from the zoomed-out screen 801 and the zoomed-out virtual keyboard 821 back to the original screen 800 and the original virtual keyboard 820.

[0183] As another example, when there is no touch input for a predetermined time, the display device 100 can switch from the minimized screen 801 and minimized virtual keyboard 821 to the original screen 800 and original virtual keyboard 820.

[0184] As another example, the display device 100 can switch from the minimized screen 801 and minimized virtual keyboard 821 to the original screen 800 and original virtual keyboard 820 based on the selection of a button (not shown) included in the minimized virtual keyboard 821.

[0185] Figure 8E This is a diagram illustrating the process of displaying a virtual keyboard based on keyboard information set in a mobile device connected to a display device when touch input is performed, according to an embodiment of the present disclosure.

[0186] The display device 100 and the mobile device 880 can connect to each other via wireless communication standards such as Wi-Fi.

[0187] When touch input is received, the display device 100 can receive information about the keyboard type set in the mobile device 880. The display device 100 can obtain information about the keyboard type from the mobile device 880 before receiving touch input.

[0188] The display device 100 can perform keyboard type matching of the second virtual keyboard 830 based on the received information about the keyboard type to have the keyboard type set in the mobile device 880.

[0189] For example, when the keyboard type of the mobile device 880 is a standard keyboard (qwerty) type, the keyboard type of the second virtual keyboard 830 can also be displayed as a standard keyboard type based on touch input.

[0190] Therefore, users can use the keyboard type used in the mobile device 880 as is, without changing the keyboard type settings of the display device 100, thus greatly improving convenience.

[0191] Figure 8F and Figure 8G This is a diagram illustrating an implementation of providing different types of virtual keyboards depending on the orientation of the display device.

[0192] The display device 100 can operate in either a horizontal or vertical mode depending on its orientation. The horizontal mode can be a horizontal mode where the horizontal length is greater than the vertical length, and the vertical mode can be a vertical mode where the horizontal length is less than the vertical length.

[0193] exist Figure 8F In the middle, the display device 100 is in landscape mode. Figure 8G In the middle, the display device 100 is in portrait mode.

[0194] Reference Figure 8F When a touch input is received in landscape mode, the display device 100 may display a second virtual keyboard 830 having a first keyboard type set in the display device 100.

[0195] Reference Figure 8G When a touch input is received in portrait mode, the display device 100 may display a third virtual keyboard 890 having a second keyboard type set in the mobile device 880 connected to the display device 100.

[0196] That is, when the display device 100 receives touch input after switching from landscape mode to portrait mode, the display device 100 can switch from a second virtual keyboard 830 having a first keyboard type to a third virtual keyboard 890 having a second keyboard type.

[0197] As described above, according to embodiments of the present disclosure, virtual keyboards with different keyboard types can be provided depending on the orientation of the display device 100, thereby providing an improved user experience.

[0198] Figure 8H This is a diagram illustrating an implementation that provides the same type of virtual keyboard even when the orientation of the display device changes.

[0199] Reference Figure 8H The display device 100 can display a second virtual keyboard 830 with a first keyboard type in landscape mode.

[0200] In this state, when the orientation of the display device 100 changes from landscape mode to portrait mode, the display device 100 can display a second virtual keyboard 830 of the same type as the first keyboard in portrait mode.

[0201] In this situation, when the keyboard type changes according to the orientation of the display device 100, the user may be confused about keyboard input due to the change in keyboard layout.

[0202] According to embodiments of this disclosure, when the second virtual keyboard 830 is displayed, even when the orientation of the display device 100 changes from landscape mode to portrait mode, the display device 100 can provide a virtual keyboard with the same keyboard type to prevent the user from being confused by keyboard input.

[0203] Similarly, when the second virtual keyboard 830 is displayed, the display device 100 can still display a virtual keyboard with the same keyboard type even when the orientation of the display device 100 changes from portrait mode to landscape mode.

[0204] Figure 9This is a flowchart illustrating a process of providing different screen brightness modes according to the type of user input, according to another embodiment of this disclosure.

[0205] Figure 9 The implementation method can be Figure 6 Detailed illustrations of steps S603 to S607.

[0206] Reference Figure 9 The controller 170 can determine whether the user input type is a remote control input type (S901).

[0207] When it is determined that the user input type is a remote control input type, the controller 170 can set the brightness mode of the display device 100 to the first screen brightness mode (S903).

[0208] When it is determined that the user input type is touch input (S905), the controller 170 can set the brightness mode of the display device 100 to the second screen brightness mode (S907).

[0209] The brightness modes of the display device 100 may include a first screen brightness mode for outputting a default brightness and a second screen brightness mode for outputting a brightness lower than the default brightness in order to save power.

[0210] Figure 10A and Figure 10B This is a diagram used to illustrate an example of providing different screen brightness modes based on the type of user input.

[0211] Reference Figure 10A When the user input type is remote control input, the display device 100 can display a first image 1001 with a first brightness on the display 180. At the same time, the display device 100 can display a first brightness pop-up window 1010 on the display 180, indicating that the display device operates in a first screen brightness mode corresponding to the default brightness.

[0212] Reference Figure 10B When the user input type changes to touch input type, the display device 100 can display a second image 1003 with a second brightness on the display 180. That is, when the user input type changes from remote control input type to touch input type, the brightness of the image can change from a first brightness to a second brightness.

[0213] The display device 100 may display a second brightness pop-up window 1030 on the display 180, which indicates that the display device operates in a second screen brightness mode. The second screen brightness mode is a power-saving mode, not the default brightness.

[0214] When the user input type is touch input, the brightness is reduced to prevent glare when the user is viewing the image due to the user being close to the display device 100.

[0215] As described above, according to embodiments of this disclosure, glare can be prevented by adjusting the output brightness of the image according to the type of user input when the user controls the input via touch.

[0216] In another embodiment, when touch input is received, instead of the brightness pop-up window 1030, the display device 100 may display a message asking to change the brightness mode or a brightness adjustment menu for adjusting the brightness.

[0217] Figure 11 This is a flowchart illustrating the process of providing images of different sizes based on the type of user input.

[0218] Figure 11 The implementation method can be Figure 6 Detailed illustrations of steps S603 to S607.

[0219] Reference Figure 11 The controller 170 can determine whether the user input type is a remote control input type (S1101).

[0220] When it is determined that the user input type is a remote control input type, the controller 170 may display a first image with a first size on the display 180 (S1103).

[0221] According to the implementation method, the first size can be the size of the entire screen of the display 180.

[0222] When it is determined that the user input type is touch input type (S1105), the controller 170 may display a second image with a second size smaller than the first image on the display 180 (S1107).

[0223] In one implementation, the second dimension may be 3 / 4 of the first dimension, but this is just an example.

[0224] Figure 12A and Figure 12B This is a diagram used to illustrate an example of providing different screen sizes based on the type of user input.

[0225] When the user input type is remote control input type, the display device 100 can display a first image 1210 with a first size on the display 180.

[0226] Reference Figure 12BWhen the user input type changes to touch input type, the display device 100 can display a second image 1230 with a second size smaller than the first size on the display 180. That is, when the user input type changes from remote control input type to touch input type, the size of the image can be reduced.

[0227] When the user input type is touch input, the image size is reduced because the image may not be clearly visible when the user is close to the display device 100.

[0228] As described above, according to embodiments of this disclosure, the size of the image is adjusted according to the type of user input so that the image can be clearly seen when controlled by the user's touch input.

[0229] According to another embodiment of this disclosure, when the user input type changes from remote control input type to touch input type, the display device 100 can reduce the size of the image from a first size to a second size, and at the same time reduce the brightness of the image from a first brightness to a second brightness.

[0230] That is, in Figure 11 In the implementation method, the following can be applied simultaneously: Figure 9 The implementation method.

[0231] Figures 13 to 14B This is a diagram used to describe an implementation that provides images of different sizes based on the type of user input.

[0232] Figure 13 The implementation method can be Figure 6 Detailed illustrations of steps S603 to S607.

[0233] exist Figures 13 to 14B In this implementation, it is assumed that the display device 100 provides a screen sharing (screen mirroring) service with the mobile device 880.

[0234] Reference Figure 13 The controller 170 can determine whether the user input type is a remote control input type (S1301).

[0235] When it is determined that the user input type is a remote control input type, the controller 170 may display a first mirror image with a first size on the display 180 (S1303).

[0236] According to the implementation method, the first size can be the size of the entire screen of the display 180.

[0237] The first mirror image may be an image corresponding to the image currently being displayed on the mobile device 880.

[0238] When it is determined that the user input type is touch input type (S1305), the controller 170 may display a second mirror image with a second size that is smaller than the first mirror image on the display 180 (S1307).

[0239] The second size could be a size that corresponds to 3 / 4 of the first size, but this is just an example.

[0240] Reference Figure 14A In portrait mode, the display device 100 may display a first mirror image 1410 on the display 180 before receiving touch input. Thereafter, when touch input is received, the display device 100 may switch from the first mirror image 1410 having a first size to a second mirror image 1430 having a second size.

[0241] This is to reduce the size of the mirrored image to facilitate touch input for users and to make the mirrored image easy to see at a glance.

[0242] Subsequently, the controller 170 can send the converted UIBC coordinate information corresponding to the touch input point on the second mirror image 1430 to the mobile device 880 via the wireless communication interface 173 (S1309).

[0243] The controller 170 can receive touch input for touching a point of the second mirror image 1430 and obtain the UIBC (User Input Reverse Channel) coordinates of the touch input point.

[0244] The user input reverse channel may be a channel for sending control signals to the mobile device 880 corresponding to touch inputs received by the display device 100 that receives images from the mobile device 880.

[0245] The controller 170 can convert the first UIBC coordinates of the touch point into second UIBC coordinates. The first UIBC coordinates can be the coordinates of the point on the first mirror image 1410 that receives the touch input, and the second UIBC coordinates can be the coordinates of the point on the second mirror image 1430, which is a scaled-down version of the first mirror image 1410.

[0246] The controller 170 can convert the first UIBC coordinates into second UIBC coordinates to match the image scaling ratio, and send the converted second UIBC coordinates to the mobile device 880. The mobile device 880 can select the corresponding point based on the received second UIBC coordinates.

[0247] Reference Figure 14B When the display device 100 receives touch input in landscape mode, the process of switching from the third mirror image 1450 being displayed to the fourth mirror image 1470 is shown.

[0248] Similar to Figure 14A In one implementation, the fourth mirror image 1470 may have a size that is scaled down compared to the third mirror image 1450.

[0249] Figures 15 to 16B An implementation method is shown for describing the operation based on whether or not the touch mode is maintained.

[0250] Figure 15 The implementation method can be Figure 6 Detailed illustrations of steps S603 to S607.

[0251] Reference Figure 15 The controller 170 can determine whether the user input type is a remote control input type (S1501).

[0252] When it is determined that the user input type is a remote control input type, the controller 170 may display a first image with a first size on the display 180 (S1503).

[0253] According to the implementation method, the first size can be the size of the entire screen of the display 180.

[0254] When it is determined that the user input type is touch input type (S1505), the controller 170 may display a second image with a second size smaller than the first image and a touch menu on the display 180 (S1507).

[0255] According to one embodiment, the touch menu may be a menu that provides a button for setting whether to maintain the touch mode. The display device 100 can receive one of an ON input for maintaining the touch mode and an OFF input for releasing the touch mode via the touch menu.

[0256] Touch mode is a mode in which the operation of the display device 100 is controlled via touch input. In touch mode, the image size can be reduced, and the image brightness can also be reduced.

[0257] Reference Figure 16A When a touch input is received, the display device 100 may display a scaled-down second image 1610 and an open touch menu 1620 on the display 180.

[0258] The controller 170 can determine whether an OFF input for turning off the touch mode is received (S1509), and when an OFF input is received, it switches from the reduced second image to the first image with the original size (S1511).

[0259] At the same time, the controller 170 can control the screen output to the original brightness of the first image.

[0260] The controller 170 can close the touch menu 1620 upon receiving an OFF input, and can switch from a scaled-down second image 1610 to a first image 1630 with the original size.

[0261] While applying the gradient effect, the scaled-down second image 1610 can be switched to the first image 1630.

[0262] In another implementation, even if no OFF input is received, the touch mode can be released when no touch input is received for a predetermined period of time.

[0263] As described above, according to embodiments of the present disclosure, when touch input is received, a selection option for maintaining the touch mode is provided to the user, thus allowing the user to more actively control the operation of the display device 100.

[0264] According to embodiments of this disclosure, the above method can be implemented on a medium containing a program using processor-readable code. Examples of processor-readable media include ROM (Read-Only Memory), Random Access Memory (RAM), CD-ROM, magnetic tape, floppy disk, optical data storage device, etc.
