FIG.1is a view of a wireless display system.

A wireless display system may include a reception module300and a transmission module100.

The reception module300may be installed to be fixed to a wall or the like.

A screen on which an image is displayed may be provided in the reception module300. The reception module300may include a display307(seeFIG.2) for displaying the image.

The display307may be implemented as any one of various panels. For example, the display307may include any one of a liquid crystal display panel (LCD panel), an organic light emitting panel (OLED panel), and an inorganic light emitting panel (LED panel).

The reception module300may receive an AV signal (audio/video signal) from the transmission module100and display an image on the display307through the received AV signal.

The AV signal may include an audio signal and a video signal.

The reception module300may wirelessly receive the AV signal from the transmission module100. For example, the reception module300and the transmission module100may transmit and receive the AV signal in a 60 GHz band. However, since a frequency band in which the reception module300and the transmission module100transmit and receive the AV signal is merely an example, it is not limited thereto.

When receiving the AV signal from the transmission module100, the reception module300may also receive a control signal for an image control.

The transmission module100may be disposed to be spaced apart from the reception module300. That is, since the reception module300and the transmission module100transmit and receive signals wirelessly, a position of the transmission module100may be flexible.

The transmission module100may be disposed in an opened space. Alternatively, the transmission module100may be disposed inside a living room cabinet or a chest of a drawer. In this case, since the transmission module100is covered by the living room cabinet or the chest of the drawer, an installation environment of the wireless display system may be created more neatly.

At least one of the reception module300or the transmission module100may receive a control signal from a remote control device200(seeFIG.2). A user may control the wireless display system using the remote control device200.

For example, the reception module300and the transmission module100may receive a power ON/OFF signal from the remote control device200and may control power according to the received power ON/OFF signal.

According to an embodiment, the reception module300may receive the control signal from the remote control device200, and the reception module300may transmit the control signal received from the remote control device200to the transmission module100.

As a specific example, the reception module300may receive the control signal from the remote control device200as IR (infrared), and the reception module300may transmit the control signal received from the remote control device200to the transmission module100through Bluetooth BT.

When the Bluetooth connection between the reception module300and the transmission module100is disconnected, the remote control device200may directly transmit the control signal to the transmission module100through Bluetooth. Here, the remote control device200may be a device capable of Bluetooth communication.

FIG.2is a control block diagram of the wireless display system ofFIG.1.

First, a method of transmitting and receiving a signal between the transmission module100, the reception module300, and the remote control device200will be described.

The remote control device200may transmit a control signal for turning on or off the power to the wireless display system. Particularly, the remote control device200may transmit a power on/off signal to the reception module300through infrared (IR). The reception module300may receive a signal for controlling power from the remote control device200through the IR.

When receiving the signal for controlling power from the remote control device200, the reception module300may transmit the received power control signal to the transmission module100. Particularly, the reception module300may transmit the power control signal to the transmission module100through the BT (Bluetooth). As the transmission module100receives the power control signal, the power may be turned on or off.

When the power is turned on, the reception module300may transmit and receive the control signal to/from the remote control device200through RF (radio frequency). Particularly, the reception module300and the remote control device200may transmit and receive control signals through the BT of RF, but this is merely an example and is not limited thereto. The control signal transmitted and received between the reception module300and the remote control device200may include various information such as voice data and motion data.

In addition, the transmission module100may transmit the AV signal to the reception module300, and the AV signal may be transmitted in a 60 GHz band. In addition, a separate communication channel may be provided between the transmission module100and the reception module300so that the control signal is transmitted. The transmission module100may transmit the control signal received from the remote control device200to the reception module300through the communication channel. In addition, according to an embodiment, the transmission module100may transmit the control signal received from the remote control device200to the reception module300through the BT in addition to the communication channel.

Since the wireless communication method between the transmission module100, the remote control device200and the reception module300, that is, communication in the IR, BT, RF and 60 GHz bands is merely an example, it is reasonable not to be limited thereto. However, for convenience of description, a communication method for transmitting the AV signal between the transmission module100and the reception module300is referred to first wireless communication, and a communication method for transmitting the control signal between the transmission module100and the reception module300is referred to second wireless communication. In some cases, the first wireless communication and the second wireless communication may be the same or different.

According to an embodiment, if the first wireless communication between the transmission module100and the reception module300is disconnected, the reception module300may not display an image on a screen. If the user who does not know that the first wireless communication is disconnected continues to press a key of the remote control device200because the image is not displayed, a problem may not be solved, and unintended results may be caused. Therefore, when the disconnection of the first wireless communication is detected, even if the control signal is not received from the remote control device200, the transmission module100may not transmit the control signal received from the remote control device200to the reception module300. That is, when the first wireless communication is disconnected, the transmission module100may ignore the control signal received from the remote control device200.

InFIG.5, (a) illustrates that a pointer205corresponding to the remote control device200is displayed on the display180.

The user may move or rotate the remote control device200up, down, left and right. The pointer205displayed on the display180of the display device100may correspond to the movement of the remote control device200. As shown in the drawings, the pointer205is moved and displayed according to movement of the remote control device200in a 3D space, so the remote control device200may be called a space remote control device.

In (b) ofFIG.5, it is illustrated that that when the user moves the remote control device200to the left, the pointer205displayed on the display180of the display device100moves to the left correspondingly.

Information on the movement of the remote control device200detected through a sensor of the remote control device200is transmitted to the display device100. The display device100may calculate the coordinates of the pointer205based on information on the movement of the remote control device200. The display device100may display the pointer205to correspond to the calculated coordinates.

In (c) ofFIG.5, it is illustrated that a user moves the remote control device200away from the display180while pressing a specific button in the remote control device200. Accordingly, a selected area in the display180corresponding to the pointer205may be zoomed in and displayed enlarged.

Conversely, when the user moves the remote control device200to be close to the display180, the selected area in the display180corresponding to the pointer205may be zoomed out and displayed reduced.

On the other hand, when the remote control device200moves away from the display180, the selected area may be zoomed out, and when the remote control device200moves to be close to the display180, the selected area may be zoomed in.

Also, in a state in which a specific button in the remote control device200is being pressed, recognition of up, down, left, or right movements may be excluded. That is, when the remote control device200moves away from or close to the display180, the up, down, left, or right movements are not recognized, and only the forward and backward movements may be recognized. In a state in which a specific button in the remote control device200is not being pressed, only the pointer205moves according to the up, down, left, or right movements of the remote control device200.

Meanwhile, the movement speed or the movement direction of the pointer205may correspond to the movement speed or the movement direction of the remote control device200.

Meanwhile, in the present specification, a pointer refers to an object displayed on the display180in response to an operation of the remote control device200. Accordingly, objects of various shapes other than the arrow shape shown in the drawings are possible as the pointer205. For example, the object may be a concept including a dot, a cursor, a prompt, a thick outline, and the like. In addition, the pointer205may be displayed corresponding to any one point among points on a horizontal axis and a vertical axis on the display180, and may also be displayed corresponding to a plurality of points such as a line and a surface.

That is, the LED module183of the transmission module100may include a plurality of LED modules. For example, the LED module183may include first and second LED modules. Here, the first LED module184may be installed on each of the side surfaces1103, and the second LED module185may be installed on the top surface1101. However, since the number and location of the LED modules are merely illustrative, this embodiment may not to be limited thereto.

The second LED module185may be installed on the rotating plate1120to rotate together as the rotating plate1120rotates.

In addition, the AV transmission unit181may be installed adjacent to the second LED module185. Thus, when the rotating plate1120rotates, the AV transmission unit181may rotate together, and as a result, a signal transmission direction of the AV transmission unit181may be changed together.

In addition, a lever1121may be installed on the rotating plate1120. The lever1121may adjust an angle at which the AV transmitter181transmits a signal. The angle at which the AV transmission unit181transmits the signal may vary according to a position of the lever1121.

The first LED module184may display power and error situations, and the second LED module185may display a wireless signal situation.

The first LED module184and the second LED module185may be disposed on different surfaces. For example, the first LED module184may be disposed on the side surface1103, and the second LED module185may be disposed on the upper surface. When the first LED module184and the second LED module185are disposed on different surfaces, if the user checks a situation of the wireless display system through the LED module from a distance, it may minimize difficulty of distinguishing which LED module is displaying which situation. Particularly, since the first LED module184for displaying a power or error situation is disposed on the side surface1103, there may be an advantage in that the user watching an image from a distance may easily check the situation. In addition, since the second LED module185for displaying the wireless signal status is disposed on the upper surface1101, there is an advantage in that information is checked only when the user needs the information.

An LED module305may also be installed in the reception module300. For example, the LED module305may be installed on one surface or at one side of the display311, but this is merely an example, and the position of the LED module305may vary.

Next, referring toFIGS.7to13, a method for operating an LED module provided in a wireless display system according to an embodiment of the present disclosure will be described.

In the present specification, power off may refer to a standby state in which an electronic device is connected to an external power source (e.g., a socket), but a screen is turned off, and only minimum power is used so that the electronic device is operable according to a user input. That is, the power off has to be distinguished from a state in which the electronic device is not connected to the external power source.

In addition, the LED modules309,184, and185may output light when turned on and may not output light when turned off. The LED modules309,184, and185may adjust a color of the light output when turned on and an output method of the light. For example, the color of the light may be red, yellow, or green, and the output method of the light may be a continuous output method or a flickering output method, but this is merely an example and is not limited thereto. It is assumed that the light is continuously output unless otherwise specified in relation to the output method.

FIG.7is a view illustrating an example of the method for operating the LED module when power of the wireless display system is turned on according to an embodiment of the present disclosure.

When the power of the reception module300is switched from the turn-off to turn-on, the LED module309may be switched from the turn-on to the turn-off. That is, when the power of the reception module300is turned off, the LED module309may be turned on, and when the power of the reception module300is turned on, the LED module309may be turned off. Therefore, when the power of the reception module300is turned on, the LED module309may not output light.

Similarly, when the power of the transmission module100is switched from the turn-off to the turn-on, the first LED module184may be switched from the turn-on to the turn-off. That is, the first LED module184may be turned on when the power of the transmission module100is turned off, and may be turned off when the power of the transmission module100is turned on.

When the power of the transmission module100is turned off, the second LED module185is turned off, and when the power of the transmission module100is turned on, the second LED module185may be turned on together. The second LED module185may output light in various manners according to a wireless communication state while the transmission module100is turned on. For example, the wireless communication state may include wireless signal strength. Specifically, the second LED module185may operates in a first mode when the wireless signal strength is strong, operate in a second mode when the wireless signal strength is normal, and operate in a third mode when the wireless signal strength is weak or disconnected.

Here, the first mode may be a mode in which green light is output, the second mode may be a mode in which yellow light is output, and the third mode may be a mode in which red light is output while flickering, but this is merely exemplary.

The wireless communication state may refer to a state of the wireless communication for transmitting and receiving the AV signal between the transmission module100and the reception module300, and in this case, the wireless communication may refer to first wireless communication inFIG.17. The first wireless communication will be described in detail with reference toFIG.17.

FIG.8is a view illustrating an example of a method for operating the LED module when the power of the wireless display system is turned off according to an embodiment of the present disclosure.

When the power of the reception module300is switched from the turn-on to turn-off, the LED module309may be switched from the turn-off to the turn-on. When the power of the reception module300is turned off, the LED module309may be turned on, and when the power of the reception module300is turned on, the LED module309may be turned off. Thus, when the power of the reception module300is turned off, the LED module309may output light.

Similarly, when the power of the transmission module100is switched from the turn-on to the turn-off, the first LED module184may be switched from the turn-off to the turn-on. For example, the first LED module184may output red light as the power of the transmission module100is turned off.

When the power of the transmission module100is switched from turn-on to the turn-off, the second LED module184may be switched from the turn-on to the turn-off. Specifically, while the second LED module185outputs light in various modes based on the wireless communication state while the power of the transmission module100is turned on, it may not output light when the power of the transmission module100is turned off. That is, when the power of the transmission module100is turned off, the second LED module185may also be turned off.

FIG.9is a view illustrating an example of a method for operating the LED module when pairing between the transmission module and the reception module is performed according to an embodiment of the present disclosure.

While the reception module300enters a pairing mode, the LED module309may output flickering light, and in particular, the light may be red, but this is merely an example. Then, when the reception module300completes pairing, the LED module309may not output light. Here, the pairing may referred to an operation in which the reception module300and the transmission module100are connected to each other.

The first LED module184of the transmission module100may output the flickering light while entering the pairing mode and may not output light when the pairing is completed. Here, the light may be green light, but this is merely an example.

In addition, the second LED module185of the transmission module100may not output light while entering the pairing mode and may output light when the pairing is completed. After the pairing is completed, the color of light output from the second LED module185may vary depending on the wireless communication state.

FIG.10is a view illustrating an example of a method for operating the LED module when the reception module of the wireless display system is not connected to an external power source according to an embodiment of the present disclosure.

When the reception module300is not connected to the external power source, the LED module309may be turned off.

Since the reception module300is not connected to the external power source, even if the remote control device200transmits a control signal for the turn-on of the power, the reception module300may not operate.

The transmission module100may operate according to a command received from the remote control device200when connected to the external power source.

When the reception module300is not connected to the external power source, and the power of the transmission module100is turned on, the first LED module184of the transmission module100may output red flickering light. Here, the color of light is merely an example. When compared to the example ofFIG.8, the first LED module184of the transmission module100may output the flickering light to inform that the reception module300is not connected to the external power source to the user.

When the reception module300is not connected to the external power source, and the power of the transmission module100is turned off, the first LED module184may output red light.

The second LED module185of the transmission module100may output light in various manners according to the wireless communication state, which is the same as described inFIG.7.

FIG.11is a view illustrating an example of a method for operating the LED module when there is no input signal is the wireless display system according to an embodiment of the present disclosure.

Even if an input signal is not detected, when the reception module300is turned on, the LED module309may be turned off. That is, the LED module309of the reception module300may operate according to the power state of the reception module300regardless of the input signal.

Similarly, the first and second LED modules184and185of the transmission module100may operate regardless of the input signal. That is, when the power of the transmission module100is turned off, the first LED module184may be turned on, and when the power of the transmission module100is turned on, the first LED module184may be off. In addition, when the power of the transmission module100is turned off, the second LED module185may be turned off, and when the power of the transmission module100is turned on, the second LED module185may output light according to the wireless communication state.

FIG.12is a view illustrating an example of a method for operating the LED module when the wireless display system is overheated according to an embodiment of the present disclosure.

When the overheating is detected, the transmission module100may output red light in which the first LED module184flickers. For example, the transmission module100may include a temperature sensor (not shown), and the controller170may control a first LED module184so that red light is output while blinking when the sensing temperature of the temperature sensor (not shown) is equal to or higher than a predetermined reference temperature.

FIG.13is a view illustrating an example of a method for operating the LED module when an error in wireless data transmission occurs in the wireless display system according to an embodiment of the present disclosure.

The transmission module100may emit the red light, in which each of the first LED module184and the second LED module185flickers when the wireless communication with the reception module300, in particular, the first wireless communication to be described later is not connected.

Since the method of operating the LED module described with reference toFIGS.7to13is merely an example, this embodiment is not limited thereto.

As described through the examples ofFIGS.7to13, the wireless display system may inform the situations such as power, error, and wireless communication through LED modules to the user.

The wireless display system may guide various information to the user through the display311. For example, the display311may display an initial setting guide screen when the wireless display system is installed.

FIG.14is a view illustrating an example of the initial setting guide screen displayed on the wireless display system according to an embodiment of the inventive concept.

For example, the display311may initially display the initial setting guide screen as illustrated inFIG.14when the wireless display system is installed.

As in the example ofFIG.14, the initial setting guide screen may display wireless communication state information1410and an installation guide1420.

The wireless communication state information1410may include wireless signal strength between the transmission module100and the reception module300, in particular, signal strength of the first wireless communication described later. For example, the wireless communication state information1410may include an icon representing the wireless signal strength.

The installation guide1420may include a text or image guiding an installation position of the transmission module100. Since the reception module300is fixed to a wall or the like, the information guiding the position of the transmission module100may be contained in the installation guide1420so that the signal is smoothly transmitted/received to/from the reception module300. For example, the installation guide1420may guide the transmission module100and the reception module300so that there is no obstruction between the transmission module100and the reception module300, may guide the rotating plate1120to be adjusted so that the second LED module185that guides the wireless communication state faces the reception module300, or may include at least one of the text or the image so that the lever1121is adjusted with reference to the wireless communication state information1410. However, since the initial setting guide screen ofFIG.14is merely an example, this embodiment may not be limited thereto.

The initial setting guide screen may also be displayed through a terminal connected to the wireless display system. Here, the terminal may mean a portable electronic device such as a smart phone.

FIG.15is a view illustrating an example of the initial setting guide screen displayed by the terminal connected to the wireless display system according to an embodiment of the present disclosure.

Particularly, (a) ofFIG.15illustrates an example of the initial setting guide screen displayed by the terminal.

The terminal may display the initial setting guide screen as illustrated in (a) ofFIG.15, and the initial setting guide screen may include wireless communication state information1510and an installation guide1520. Since each of the wireless communication state information1510and the installation guide1520is the same as the wireless communication state information1410and the installation guide1420described inFIG.14, duplicate descriptions will be omitted. That is, although the text or image is omitted in the installation guide1520ofFIG.15, at least one of the text or image shown in the installation guide1420ofFIG.14may be contained.

The terminal may further display various function setting screens in addition to the initial setting guide screen. For example, the function setting screen may include an artificial intelligence function setting screen as illustrated in (b) ofFIG.15and a password setting screen as illustrated in (c) ofFIG.15.

The artificial intelligence function setting screen may be a screen for setting at least one of an artificial intelligence image quality setting function or an artificial intelligence sound quality setting function. The password setting screen may be a screen for setting a password for locking or unlocking a channel or an input.

However, the screens illustrated inFIG.15are merely examples, and the terminal may display various screens for setting functions related to the wireless display system or controlling the wireless display system.

The wireless display system may display a screen for setting a wireless communication connection environment even after the initial setting.

FIG.16is a view illustrating an example of a screen for explaining the wireless communication connection environment displayed on the wireless display system according to an embodiment of the inventive concept.

For example, as illustrated in (a) ofFIG.16, the display311may display a menu for setting various functions related to the use of the wireless display system. At least one of the menus may be an item for setting the wireless communication connection environment.

When the item for setting the wireless communication connection environment is selected, the display311may display a screen containing the wireless communication state information1610and the installation guide1620as illustrated in (b) ofFIG.16. Since each of the wireless communication state information1610and the installation guide1620is the same as the wireless communication state information1410and the installation guide1420described inFIG.14, duplicate descriptions will be omitted. That is, although the text or image is omitted in the installation guide1620ofFIG.16, at least one of the text or image shown in the installation guide1420ofFIG.14may be contained.

In the wireless display system, since the transmission module100and the reception module300transmit and receive signals wirelessly, an connection error in wireless communication may occur. Thus, the wireless display system according to an embodiment of the present disclosure may detect the connection error of the wireless communication and display a guide for removing the error. Particularly, since the wireless display system according to an embodiment of the present disclosure uses a plurality of wireless communication technologies, it is intended to accurately and quickly remove errors by displaying an error elimination guide suitable for the wireless communication technology in which the error occurs.

FIG.17is a flowchart illustrating a method for operating the wireless display system according to an embodiment of the present disclosure.

Power of at least one of the transmission module100or the reception module300may be turned on (S11).

At least one of the transmission module100and the reception module300may switch the power from turn-off to turn-on as a power on signal is received.

At least one of the transmission module100and the reception module300may obtain whether the first wireless communication is connected while the power is turned on (S13).

That is, at least one of the transmission module100and the reception module300may determine whether the first wireless communication is connected while the power is turned on.

The first wireless communication may refer to a wireless communication method of transmitting an AV signal from the transmission module100to the reception module300. The first wireless communication may refer to a wireless communication method using a band of 60 GHz. For example, the first wireless communication may be WiGig (Wireless Gigabits), IEEE 802.11ay, etc., but is not limited thereto. The second wireless communication to be described later may be Bluetooth (BT). That is, the first wireless communication may use a frequency of about 60 GHz, and the second wireless communication may use a frequency band of about 2.4 to 2.485 GHz. However, this is merely an example and is not limited thereto.

As described above, the transmission module100and the reception module300may transmit and receive a signal through a plurality of wireless communication, for example, the first wireless communication and the second wireless communication described later. Specifically, the transmission module100and the reception module300may transmit and receive the AV signal through the first wireless communication and may transmit and receive the signal (e.g., control signal) excluding the AV signal through the second wireless communication. As described above, there is an advantage of minimizing a signal interference by distinguishing between wireless communication for transmitting and receiving the AV signal and wireless communication for transmitting and receiving other signals. Particularly, since the AV signal is continuously transmitted and received while the wireless display system is operating, the signal interference may be minimized by using a communication method different from other signals, that is, a different frequency band.

If at least one of the transmission module100or the reception module300is not connected to the first wireless communication, it is possible to obtain whether the second wireless communication is connected (S15).

At least one of the transmission module100or the reception module300may determine whether the second wireless communication is connected when the first wireless communication is not connected.

When the second wireless communication is connected, at least one of the transmission module100or the reception module300may display a guide for the first wireless communication connection (S17).

When the first wireless communication is not connected, the display311may be turned on, but a normal screen may not be displayed. That is, when the first wireless communication is not connected, the display311may be turned on, but the image may not be normally displayed.

In addition, when the first wireless communication is not connected, the second LED module183of the transmission module100may output flickering red light.

The display311may display a guide for normally connecting the first wireless communication.

The display311may display a guide stored in the memory313when the reception module300and the transmission module100are not connected through the first wireless communication. The guide for connection of the first wireless communication may be stored in the memory313.

FIGS.18to20are view illustrating an example of a guide displayed for first wireless communication connection through the reception module according to an embodiment of the present disclosure.

The guide may be a guide for connecting the first wireless communication.

The memory313may store one guide, and the display311may continuously display the one guide stored in the memory313until the first wireless communication is connected.

Alternatively, the memory313may store a plurality of guides, and the display311may sequentially and repeatedly display the plurality of guides stored in the memory313at predetermined periodic intervals until the first wireless communication is connected.

FIG.18illustrates an example of a first guide of the plurality of guides,FIG.19illustrates an example of a second guide of the plurality of guides, andFIG.20is illustrates an example of a third guide of a plurality of guides.

Referring toFIG.18, the first guide includes at least one of an image instructing that a distance between the transmission module100and the reception module300is required to be adjusted and an image instructing that an obstacle is required so as not to be placed between the transmission module100and the reception module300.

Referring toFIG.19, the rotating plate1120may be directed toward the reception module300, and the second guide may include an image instructing that the second LED module185is required to be adjusted.

Referring toFIG.20, the third guide may include an image instructing that the lever1121is required to be adjusted so that the second LED module185faces the reception module300.

Since the above-described first to third guides are merely examples, this embodiment is not limited thereto.

The display311may display a guide for the first wireless communication connection and may receive and display an image from the transmission module100when the connection of the first wireless communication is detected.

Again,FIG.17will be described.

If at least one of the transmission module100or the reception module300is not connected to the second wireless communication, a pairing error may be acquired (S19).

That is, if at least one of the transmission module100or the reception module300is not connected to the second wireless communication, it may determine whether the pairing error occurs.

When it is determined that at least one of the transmission module100or the reception module300is not in the state of the pairing error, a guide for the second wireless communication connection may be displayed (S21).

If it does not correspond to the pairing error, it may correspond to a case in which the second wireless communication is temporarily disconnected due to factors such as surrounding environments. Thus, in this case, the display311may display a guide for the second wireless communication connection.

When the second wireless communication is not connected, even if the remote control device200transmits a control signal, at least one of the transmission module100or the reception module300may not operate according to the control signal transmitted by the remote control device200.

If the first wireless communication is connected even though the second wireless communication is not connected, the display311may normally output an image.

In addition, since the signal transmitted by the remote control device200reacts after being received by the reception module300and transmitted to the transmission module100, if the transmission module100is not connected to the external power source, even if the display311is normally outputting the image, there may be no reaction according to the signal of the remote control device200. Thus, even though the transmission module100has a power supply problem, it may be mis-recognized as a connection problem of the second wireless communication.

Thus, the display311may further display a power check guide of the transmission module100before displaying the guide for the second wireless communication connection.

FIG.21is a view illustrating example of the guide displayed for checking power of the transmission module through the reception module according to an embodiment of the present disclosure.

When displaying the guide for the connection of the second wireless communication, the display311may display the guide for checking the power of the transmission module before displaying the guide for the connection of the second wireless communication.

The guide for checking the power of the transmission module may be stored in the memory313in the form of an image. As in the example ofFIG.21, the guide for checking the power of the transmission module may include a message requesting the check of the power of the transmission module to the user.

After displaying the guide for checking the power of the transmission module, the display311may display the guide for the second wireless communication connection as in the example illustrated inFIG.22.

FIG.22is a view illustrating an example of the guide displayed for second wireless communication connection through the reception module according to an embodiment of the present disclosure.

Similarly, the guide for the second wireless communication connection may be stored in the memory313in the form of an image. As in the example ofFIG.22, the guide for the second wireless communication connection may include an image (or message) requesting turn-off of second wireless communication of neighboring devices.

Again,FIG.17will be described.

The reception module300may display the guide for the second wireless communication connection, and when the connection of the second wireless communication is detected, it may be confirmed whether the first wireless communication is connected (S25). Since this is the same as that described in operation S13, redundant description will be omitted.

Again,FIG.17will be described.

If at least one of the transmission module100or the reception module300is in state of the pairing error, a guide for repairing may be displayed (S23).

In the case of the pairing error, the display311may display the guide for repairing. The guide for repairing may be stored in the memory313in the form of an image.

FIG.23is a view illustrating an example of the guide displayed for repairing through the reception module according to an embodiment of the present disclosure.

The repairing may require resetting at least one of the transmission module100or the reception module300. Therefore, as illustrated in (a) ofFIG.23, the guide for repairing may include a first message requesting pressing of a button provided in the transmission module100for a set time and a second message requesting pressing of a button provided in the reception module100for a set time. According to an embodiment, the first message and the second message may be displayed simultaneously as illustrated in (a) ofFIG.23or displayed separately and sequentially unlike in (a) ofFIG.23.

In addition, the guide for repairing may further include a QR code, and the QR code may guide an installation method/customer center and the like.

While the display311displays the guide for repairing, the first LED module184of the transmission module100may output flickering green light, and the LED module305of the reception module300may output flickering red light.

The display311may display the guide for repairing, and when the repairing is in progress, the display311may display a repairing progress guide as illustrated in (b) ofFIG.23.

If the repairing fails, the display311may display the guide for repairing again.

When the repairing is completed, the reception module300may check whether the first wireless communication is connected (S25). Since this is the same as that described in operation S13, redundant description will be omitted.

All of the guides for the first wireless communication connection, the guide for the second wireless communication connection, and the guide for repairing described above may be stored in the reception module300, and thus, the guides may be output normally.

In addition, each of the guide for the first wireless communication connection, the guide for the second wireless communication connection, and the guide for repairing may be continuously displayed until the problem is solved, and the display311may move the display position of the guide to display the afterimage to minimize the problem.

FIG.24is a view illustrating an example of a method for displaying the guide through the reception module according to an embodiment of the present disclosure.

When displaying the guide stored in the memory313, the display311may adjust the guide to ¼ or less of the entire screen, and as illustrated inFIG.24, the guides may be sequentially displayed at the first position, the second position, the third position, and the fourth position.

When the display311displays the guide, a position of the guide may be changed every predetermined period.

Thus, there are advantages of minimizing the case in which the guides are continuously displayed at specific positions, and also, minimizing the occurrence of afterimages.

The transmission module100and the reception module300may display an image when the first wireless communication and the second wireless communication are connected (S27).

That is, the transmission module100may transmit an image signal to the reception module300, and the reception module300may display an image on the display311according to the image signal received from the transmission module100.

At least one of the transmission module100or the reception module300may detect an operation error while displaying the image (S29).

The operation error may include video interruption due to a decrease in signal strength of the first wireless communication, failure of a temperature sensor, overheating, and disconnection of the second wireless communication, but these are merely examples.

When a problem occurs that at least the first wireless communication is disconnected, the display311may display the guide stored in the memory313. However, if the first wireless communication is connected, the reception module300may receive the guide from the transmission module100to display the guide on the display311.

Specifically, when the operation error occurs, the display311may receive the guide from the transmission module100to display the received guide. For example, when the first wireless communication is connected, and only the second wireless communication is disconnected, the transmission and reception of the AV signal is possible, and thus, the transmission module100may transmit the guide stored in the transmission module100to the reception module100, and the reception module300may display the guide received from the transmitting module100on the display311.

As described above, when the guide related to the disconnection of the first wireless communication is stored in the reception module300, the guide may be displayed normally, and the guide stored in the reception module300may be minimized, that is, the memory313may be minimized, and thus, there is an advantage in that the size of the reception module300is minimized.

The transmission module100and the reception module300may display an image when an operation error is not detected.

When the operation error is detected, the transmission module100and the reception module300may receive and display a guide corresponding to the detected operation error from the transmission module100(S31).

FIG.25is a view illustrating an example of a guide displayed by being received from the transmission module through the reception module according to an embodiment of the present disclosure.

As in the example ofFIG.25, the display311may display a guide indicating that power is to be turned off due to the failure of the temperature sensor.

In addition, when the signal strength of the first wireless communication is weak, the display may receive and display the screen as illustrated inFIG.16from the transmission module100so that the display311guides the wireless communication situation and then set the wireless communication connection environment between the transmission module100and the reception module300.

As described above, when the reception module300receives the guide from the transmission module100, there is an advantage in that the guide is displayed in a text format without being limited to the image because language conversion is free.

To summarize the method for operating the wireless display system, the reception module300may display the guide stored in the memory313on the display311when the wireless communication with the transmission module100is not connected. That is, the wireless communication may include first wireless communication for receiving the image signal from the transmission module100and second wireless communication for receiving the control signal from the transmission module100, and the display311may be configured to display at least one guide stored in the memory313when at least one of the first wireless communication or the second wireless communication is not connected.

Particularly, even when the second wireless communication is not connected, the guide stored in the reception module300may be displayed. As the reception module300does not transmit the control signal to the transmission module100, the transmission module100may not transmit any signal to the reception module300. Specifically, when the remote control device200transmits the control signal as IR, since the reception module300receives the control signal from the remote control device200, and the reception module300transmits the control signal to the transmission module100in a Bluetooth transmission method, if the transmission module100does not receive the control signal from the reception module300, the remote control device200may also recognized as being disabled so as not to transmit the guide to the reception module300. Therefore, even in this case, the reception module300may display the guide stored in the memory313by itself.

When the first wireless communication is not connected, the display311may be configured to display different guides when the second wireless communication is not connected and when a pairing error occurs (300) between the transmission module100and the reception module300. Specifically, the display311may be configured to: display a guide for adjusting an installation environment of the transmission module100or the reception module300when the first wireless communication is not connected; and display a guide for turning off the second wireless communication of a peripheral device or a guide for repairing when the wireless communication is not connected. The display311may be configured to display the guide for requesting the power check of the transmission module100before displaying the guide for turning off the second wireless communication of the peripheral device.
