FIG. 3 is a conceptual diagram showing the mutual operation of the video display device 100 and the external input device 200 according to the present invention. Here, a television receiver is shown as an example of the video display device 100, and a remote controller is shown as an example of the external input device 200. [

Referring to FIG. 3, the external input apparatus 200 may transmit or receive a signal with the image display apparatus 100 according to an RF communication standard. A control menu may be displayed on the screen of the video display device 100 according to the control signal of the external input device 200. [ The external input device 200 includes a plurality of buttons, and can generate an external input signal according to a user's operation of the button.

In the present invention, the external input device 200 may be a remote controller, and the remote controller transmits and receives signals to and from the interface unit 140 of the image display device 100 without a button operation. Thereby further shortening the user's boot-up time. Hereinafter, such a mechanism will be described in more detail.

4 is a conceptual diagram showing an example of a process for shortening the perceived boot time in the video display device of the present invention.

To implement the illustrated process, the sensor portion of the image display device 100 is configured to receive at least one of the first and second drive signals from the remote control. The sensor unit is configured to sense input signals from the remote controller 201, for example, a remote controller, and may be provided in the main body 101 of the image display apparatus 100 . Here, the second driving signal may be a signal generated by an operation of a button provided on the remote controller 201. More specifically, the second drive signal is a power supply signal for turning on the power of the main body 101, and the button may be a power button.

Referring to FIG. 3, the video display device 100 senses the state of the remote controller 201 before receiving the second driving signal. If the state of the remote controller 201 corresponds to a set condition, 170 are deactivated and the control unit 150 (see FIG. The boot mode (hereinafter, referred to as 'first mode') is a mode in which the display unit 170 is powered off, that is, the display unit 170 and the control unit 150 are deactivated, And the controller 150 is defined as a state in which the controller 150 enters the booting state.

The first mode is a concept distinguished from a power saving mode in which the display unit 170 is inactivated in a power-on state. Accordingly, the first mode is a state of waiting for input during the full boot of the video display device, and only the CPU, RAM, and some peripheral devices can be booted. In this case, the standby power may vary depending on how far the boot is advanced. For example, the standby power in the first mode may be set to 10 W or less. On the other hand, in the state that the power of the video display device is turned off, the standby power can be 0.1 W or less.

According to the example, the set condition of the remote controller 201 for switching to the first mode may be the movement of the remote controller 201. [ More specifically, the first driving signal is a signal generated by the motion of the remote controller 201. When the image display device 100 receives the first driving signal in a state in which the power is off, . In operation S120, the remote controller detects the movement of the video display device in the off state, and transmits the first driving signal to the video display device in step S120. Upon receiving the first driving signal, the video display device proceeds to the first stage boot and executes the first mode (S130).

In order to generate the first driving signal, the remote controller 201 may include a sensor (not shown) and a transmitter (not shown).

The sensor is configured to detect movement of the remote controller 201 and may include a motion sensor such as a gyro sensor 231, an acceleration sensor 232 (see FIG. 2), an ultrasonic sensor, And the remote controller may be implemented as a remote control device that senses an operation in a space and generates an input signal using the motion sensor.

The transmitter may be configured to transmit signals to and receive signals from the video display device 100 as an example of the wireless communication unit 210. [ For example, the RF module 211 or the IR module 212 (see FIG. 2) transmits the first driving signal to the image display device in accordance with the communication standard.

Next, when the video display device receives the second driving signal in the first mode, a second mode in which the display is activated is executed (S140). That is, when the power button of the remote controller is pressed in the first mode, the two-step booting is performed, and the devices that were not activated in the first mode are activated. As an example of this, the screen of the display unit is turned on.

As described above, since the first mode which is a semi-boot state is executed by using the state of the remote controller before the power of the video display device is completely turned on, the effect of reducing the user's feeling- do. That is, the booting process proceeds from the moment the user grasps the remote control device to operate the device, but the user does not perceive the booting process. Therefore, the user recognizes that the power is increased in a short time after the operation of the power button.

In addition, in this embodiment, measures for further reducing standby power are presented. As an example, if there is no input for a predetermined period of time in the first mode, the image display device can be restored to a power-off state (S150). For example, the control unit detects whether the second driving signal is received in the first mode, and returns the display unit and the control unit to an inactive state if the second driving signal is not received for a predetermined time.

As another alternative, when the second driving signal is received while the control unit is booting, the display unit may be activated. That is, when the second driving signal is received during the booting of the control unit by the execution of the first mode, the booting is immediately followed from the point of time when the second driving signal is received to the booting for the execution of the second mode. For this operation, the video display device is configured to be able to receive and process the second drive signal even during execution of the first mode.

Also, in this embodiment, the second drive signal can be processed with priority to the first drive signal. For example, if the first and second driving signals are simultaneously received or the second driving signal is received first, the booting to the second mode may proceed immediately after the power of the video display device is turned off. Furthermore, when the button is operated in the second mode, the power of the video display device is turned off. That is, when the video display device receives the power off signal in the second mode, it immediately turns off the power without entering the first mode.

In the above description, the embodiment has been described in which the user's sensation booting time is shortened by using the motion detection of the remote controller, but this can be modified into various forms. Hereinafter, an embodiment will be described in which the first mode is executed by sensing the user's grip on the remote controller.

FIG. 5 is a conceptual diagram of another embodiment of the image display device of the present invention, and FIG. 6 is a perspective view showing a structure of the remote controller of FIG.

In this embodiment, when the user's grip on the remote controller is detected, the video display device executes the first mode. 5 is the same as that of steps S130 to S150 shown in FIG. 4, and therefore, the description of FIG. 4 is applied mutatis mutandis.

According to the illustration of FIG. 5, the first drive signal is generated based on the user's grip on the remote control. That is, the remote controller detects the user's grip on the user (S210), and transmits the first driving signal to the image display device when the grip is sensed (S220). Since the grip of the user is the basis for starting the boot, the user's perceived boot time can be further shortened.

In order to implement the above process, the remote controller 300 includes a sensor 301 for sensing a contact to one surface of the remote controller 300, and a transmitter (not shown) for transmitting the first drive signal when the contact is sensed Quot;). The configuration of the transmission unit can be applied as it is in the description of FIG. 4, and therefore, a description thereof will be omitted.

6, the remote controller 300 includes front and rear surfaces, and a button (or a power button 302) for receiving generation of a second driving signal is disposed on the front surface, And may be arranged to sense the user's contact with the rear surface.

As an example, the sensor 301 may be a touch sensor that senses a touch on the rear surface. If the user touches the rear surface, a first driving signal can be generated. However, the present invention is not limited thereto, and the sensor may sense a touch (or contact) of the user with respect to any part of the side surface of the remote controller, thereby generating the first driving signal.

 In this case, whether or not the first drive signal is generated can be determined by the degree of the user's grip (amount of contact with the rear surface). More specifically, when the user senses the area touching the rear surface or the side surface of the remote controller and reaches a predetermined size, the sensor 301 generates a first driving signal to prevent malfunction.

As a modification of the sensor 301, the sensor may be an illuminance sensor or a pressure sensor. In the case of the illuminance sensor, the user senses that the illuminance is lowered when the user holds the remote control, and generates the first driving signal. In the case of a pressure sensor, the user senses the force of holding the remote controller and generates a first driving signal. As such, the user ' s grip on the remote control can be detected in various forms.

In another embodiment, the video display device can operate in conjunction with the mobile terminal. As an example of this, an embodiment in which a video display device is interlocked with a mobile terminal and a home appliance network will be described first. 7 is a conceptual diagram of another embodiment of the video display device of the present invention.

According to the present embodiment, the remote controller in the present embodiment is extended to a concept including the mobile terminal 400 and the remote controller 500.

The mobile terminal 400 is capable of wireless communication and can be divided into a handheld terminal and a vehicle mount terminal according to whether the user can carry the mobile phone directly. For example, the mobile terminal may include a mobile phone, a smart phone, a laptop computer, a tablet, a digital broadcasting terminal, a PDA (personal digital assistant), a portable multimedia player (PMP) .

In this embodiment, the mobile terminal 400 generates the first driving signal, and the remote controller 500 generates the second driving signal and transmits the second driving signal to the video display device 100. The second driving signal is generated when a user operates a button of the remote control, similar to the previous embodiment, but the first driving signal is generated when the mobile terminal 400 enters a specific area. As an example, a first drive signal may be generated so that the image display device senses it when the user comes home after going out. In order to implement this operation, the specific area may be an area where the mobile terminal 400 is connected to a home appliance network.

The home appliance network has a home server H in which devices such as a PC and a set-top box are constructed for each home and a unique IP address is given using a LAN, a wired telephone network, a wireless data network, And will operate it. The home server H transmits and receives data through the protocol defined by the video display device 100 or the mobile terminal 400 as a kind of data transmission / reception protocol. An application for accessing a home appliance network may be installed in the mobile terminal, and a specific mobile terminal can be registered in the home appliance network through the application.

The mobile terminal 400 is connected to the home server H through a wireless data network such as Wi-Fi at step S310. When the mobile terminal 400 is connected to the home server H, To the display device 100 (S320). Thereafter, when the image display apparatus 100 receives the first drive signal, the image display apparatus 100 proceeds to the first stage boot and executes the first mode (S330). Next, when the image display device receives the second driving signal in the first mode, a second mode in which the display is activated is executed (S340). The second driving signal is generated by the operation of the power button of the remote controller do.

In this case, the controller 150 (see FIG. 1) operates to turn off the power of the video display device 100 when the second driving signal is not received in the first mode while the mobile terminal 400 is connected to the home appliance network (S350). According to this operation, the power of the image display device is turned off when the user enters a specific area, that is, the home, but does not intend to turn on the image display device, so that consumption of the standby power can be prevented.

Hereinafter, a booting operation associated with the operation of the remote control application of the mobile terminal will be described as another example in which the video display device operates in conjunction with the mobile terminal. FIG. 8 is a conceptual diagram of another embodiment of the video display device of the present invention, and FIG. 9 is a conceptual diagram showing each state of the mobile terminal of FIG.

According to the illustration, the remote controller may be a mobile terminal 600 in this embodiment. The mobile terminal 600 is capable of executing a remote control application, and a power button may be output along with a number button capable of touch input on the GUI of the remote control application.

Referring to these drawings, the first driving signal is transmitted to the video display device together with the execution of the remote control application (S410) in the mobile terminal (S420). Thereafter, the image display apparatus 100 receives the first driving signal and proceeds to the first-stage boot to execute the first mode (S430). Next, when the video display device receives the second driving signal in the first mode, a second mode in which the display is activated is executed (S440). The second driving signal is generated by touching the power button of the remote control application . In this case, the execution of the remote control application is shown in the first figure of Fig. 9, and the touch of the power button is shown in the second figure.

Unlike the previous embodiment, the controller 150 (see FIG. 1) does not perform the operation of turning off the image display device 100 even if the second drive signal is not received while the remote control application is being executed. Since the execution of the remote control application is likely to be for use of the image display device, the power of the image display device is not turned off.

Information related to the mode of the image display device may be output to the GUI of the remote control application. As an example of this, when the first mode is being executed, information indicating this to the GUI (for example, during execution of the boot mode) is output.

Further, this embodiment can be combined with the foregoing embodiment. For example, the video display device operates according to the embodiment of FIG. 7 before the remote control application is executed, and may operate according to the embodiment of FIG. 8 when the remote control application is executed. As another example, either the embodiment of FIG. 7 or the embodiment of FIG. 8 may selectively operate according to the user's setting.
