Description

DISPLAY DEVICE AND METHOD OF CONTROLLING THE SAME

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly, to a display device that performs an operation corresponding to a command input through a remote controller and an operation control method thereof.

In general, a remote controller is used to remotely control household appliances or information appliances. The remote controller is a short for `Remote Controller` which means` to control the machine wirelessly from far away`, and it is used in most household appliances recently.

The remote controller uses an infrared ray having a lower frequency than a visible ray. The remote controller is an apparatus for controlling an electronic device such as a TV, an air conditioner, and a VCR by generating an infrared signal according to a key input from a user.

Such a remote control can be used not only in a home but also anywhere an electronic device is installed.

Usually, the most common place for remote control is a living room of a normal household, and the target is a television.

In general, when a user inputs a specific key through a remote controller, the remote controller transmits an infrared signal corresponding to the input key to the light emitting diode. Then, the light receiving diode of the remote control signal receiving unit built in the electronic product such as TV or audio receives the infrared signal transmitted from the remote control and performs the operation corresponding thereto.

However, as the number of functions provided in the display device has increased in recent years, the number of keys provided in the remote controller is also increasing, and a user can not efficiently input a desired key.

For example, since a remote controller has a large number of keys in a predetermined space, when a user desires to input a first key, a second key adjacent to the first key may be input.

Also, even if the parents set the use restriction on a specific channel or a specific function, the children may easily use the remote control to view the restricted use channel, or use the limited use function .

Therefore, there is a demand for a remote controller that can improve the efficiency and user convenience.

According to the embodiment of the present invention, a key that is not desired to be used among the keys provided in the remote controller is deactivated so that even if the key is input later, the corresponding operation is not performed.

Further, in the embodiment of the present invention, when a specific key is inputted through the remote controller, it is possible to determine whether or not to perform the operation according to the input key based on the frequency of use of the specific key.

 It is to be understood that the technical objectives to be achieved by the embodiments are not limited to the technical matters mentioned above and that other technical subjects not mentioned are apparent to those skilled in the art to which the embodiments proposed from the following description belong, It can be understood.

According to an embodiment of the present invention, there is provided a display device including a storage unit storing inactive key information; An infrared receiver for receiving an infrared signal transmitted from a remote controller; And a controller for analyzing the infrared signal received through the infrared receiver to check the key information inputted from the remote controller and comparing the confirmed key information and the deactivation key information to determine whether to perform the operation corresponding to the inputted infrared signal And a control unit for determining the control unit.

According to another aspect of the present invention, there is provided a method of controlling an operation of a display device, including: receiving an infrared signal transmitted from a remote controller; Comparing the key information corresponding to the received infrared signal with previously stored inactive key information; Ignoring the received infrared signal if key information corresponding to the received infrared signal is present in the previously stored deactivation key information; And performing an operation corresponding to the received infrared signal if there is no key information corresponding to the received infrared signal in the previously stored inactive key information.

According to the display device and the operation control method thereof according to the embodiment of the present invention, when the user does not need a plurality of keys provided in the remote controller, the simple remote controller setting function can be provided to increase the usability of the remote controller, Determining whether or not to perform an operation according to the key input from the remote controller according to the frequency count can prevent the user from performing an undesired operation according to the wrong input of the remote control key.

In addition, according to the embodiment of the present invention, it is possible to provide a more efficient and easy-to-use restriction function by selectively deactivating the input switching key for a numeric key for switching to a specific channel or switching to an external input have.

The proposed embodiment will be described.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. It should be understood, however, that there is no intention to limit the scope of the present invention to the embodiment shown, and other embodiments which are degenerative by adding, changing or deleting other elements or other embodiments falling within the spirit of the present invention Can be proposed.

Although the term used in the present invention is a general term that is widely used at present, there are some terms selected arbitrarily by the applicant in a specific case. In this case, since the meaning is described in detail in the description of the corresponding invention, It is to be understood that the present invention should be grasped as a meaning of a non-term.

That is, in the following description, the word 'comprising' does not exclude the presence of other elements or steps than those listed.

1 is a diagram illustrating a configuration of a display system according to an embodiment of the present invention.

1, the display system includes a remote controller 10 for transmitting key code information corresponding to a key input from a user as an infrared signal, and an infrared signal receiver for receiving an infrared signal transmitted through the remote controller 10 A display device 100 for checking key information corresponding to the received infrared signal, performing an operation corresponding to the received infrared signal, or ignoring the received infrared signal.

When a specific key is input from the user, the remote controller 10 transmits the input key to the display device 100 as an infrared signal.

Here, the remote controller 10 substantially comprises a key panel for receiving various key signals from a user, a key code generator for generating a key code corresponding to the key signal inputted through the key panel, A modulation / amplification unit for modulating an oscillation frequency generated through the key code generated through the code generation unit and the oscillation unit and amplifying the oscillation frequency to a predetermined level, and a modulating / amplifying unit for modulating / And an infrared ray transmitter for generating and transmitting infrared ray light according to an output electrical signal.

The display device 100 performs an operation corresponding to the infrared signal transmitted through the remote controller 10.

The display apparatus 100 includes a menu screen generating unit 110 for generating a menu screen for setting various functions, a display unit 120 for displaying the generated menu screen, An infrared receiver 140 for receiving an infrared signal transmitted through the remote controller 10 and a controller 130 for checking the key information corresponding to the infrared signal received through the infrared receiver 140, And a controller 150 for determining whether to perform an operation corresponding to the received infrared signal based on the identified key information.

Hereinafter, a method of controlling the operation of the display apparatus according to the first embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a flowchart for explaining steps of setting a deactivation key of a display device according to the first embodiment of the present invention. FIG. 3 is a flowchart illustrating a method of controlling an operation of a display device according to a first embodiment of the present invention, 4 is a diagram illustrating an example of a message formed by the first embodiment of the present invention.

As shown in FIG. 2, the control unit 150 determines whether an infrared signal corresponding to the use restriction key setting is input through the infrared receiver 140 (step 200). That is, in the first embodiment, the inactivation key can be directly set by the user. In the second embodiment, an arbitrary key can be automatically set to an inactive key based on the frequency of use of the key. Accordingly, the user can input a use restriction key setting command for setting the inactivation key through the remote controller 10 or a separately provided local key.

If the infrared signal corresponding to the usage restriction key setting is input, the controller 150 displays a remote control key screen for setting the usage restriction key in operation 210. At this time, image information on the remote control key screen for setting the use restriction key is stored in the storage unit 130. The menu screen generation unit 110 generates a menu key for setting the use restriction key using the stored image information, And the generated menu screen is displayed through the display unit 120. [0033] FIG.

At this time, the displayed remote control key screen may be provided as an image having the same shape as that of the remote controller 10 currently operated by the user. That is, since the user generally controls the operation of the display device using the remote controller provided at the time of initial purchase of the product, the product manufacturer may store the image data of the shape corresponding to the remote controller initially provided, (130).

In addition, since the user can control the operation of the display device using a separately purchased remote controller, the product manufacturer can store the separate image data in the storage unit 130 in order to control the operation of the display device. That is, the key information of the remote controller that can be used in the display device may be generated as separate image data, and may be stored in the storage unit 130.

Accordingly, the user can set the usage restriction key by selecting any one of the image data to be displayed through the display unit 120 among the various image data.

The controller 150 determines whether a specific key is selected on the displayed menu screen (operation 220). That is, the control unit 150 determines whether a specific key for setting the use restriction is selected on the displayed remote control key screen.

If the specific key is selected, the controller 150 checks information about the selected specific key (operation 230). That is, since the key selection is selected by inputting the remote controller or the separate local key, the controller 150 analyzes the command inputted from the outside, and accordingly, Check whether it is a kind of key.

At this time, if the specific key is selected as described above, the control unit 150 displays a separate password input window, thereby effectively preventing the child's unintentional use restriction setting. Here, in order to input the above-mentioned password, a numeric key must be input. However, since the use restriction of the key set by the password may be set, the use restriction of all keys is released at the time of inputting the password.

If the information about the selected specific key is confirmed, the control unit 150 stores the identified key information as the inactivation key information in the storage unit 140 (operation 240).

If the use restriction key setting termination command has been input, the control unit 150 returns to step 210, and if the use restriction key setting termination command has been input, The operation of setting the use restriction key is terminated, or the operation of setting the use restriction key is terminated (operation 250).

In this manner, the user can use the remote control key screen displayed through the display unit 120 to display a key that he / she does not use well, a numeric key for preventing switching to a specific channel, It is possible to easily set the use restriction on the key for function execution.

 Referring to FIG. 3, when the use restriction key setting of the remote controller is completed, the controller 150 periodically checks whether the infrared signal is received through the infrared receiver 140 (step 300). That is, the controller 150 determines whether the user inputs a key for executing a specific function, a key for switching to a specific channel, a key for adjusting a volume level, or the like through the remote controller 10.

If the infrared signal received through the infrared receiver 140 exists, the controller 150 analyzes the received infrared signal to check the key information input by the current user in operation 310.

In step 320, the controller 150 determines whether the checked key information is the disabled key information. That is, the control unit 150 compares the confirmed key information with the deactivation key information stored in the storage unit 130 in advance. The controller 150 determines whether the key information matching the identified key information exists in the stored key information stored in the storage unit 130 as a result of the comparison.

If the determined key information is the inactivated key information, the controller 150 ignores the received infrared signal (step 330). That is, the operation corresponding to the received infrared signal is not performed and the previous operation state is maintained.

In step 340, the control unit 150 displays a message indicating that the operation corresponding to the received infrared signal is not performed and is ignored.

4, on one side of the display screen 400, a message informing that the input key is a restricted use key and a message 410 for canceling a predetermined use restriction are displayed to use the key . Accordingly, the user can execute a separate use restriction release operation to release the use restriction of the key to activate the key.

If the determined key information is not the deactivated key information, the control unit 150 performs an operation corresponding to the received infrared signal (operation 350).

As described above, in the first embodiment, since the user has directly set the deactivation key, unless the use restriction release is set separately, the key whose use restriction has been previously set remains in the use restriction state.

Hereinafter, the operation of the display device according to the second embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 5 is a flowchart for explaining steps of setting a deactivation key of a display device according to a second embodiment of the present invention. FIG. 6 is a flowchart illustrating a method of controlling an operation of a display device according to a second embodiment of the present invention. 7 is a diagram illustrating an example of a message formed by the second embodiment of the present invention.

Referring to FIG. 5, the control unit 150 checks cumulative input count information of each pre-stored key (operation 500). That is, when the infrared signal is received through the infrared receiver 140, the control unit 150 checks the key information corresponding to the received infrared signal, and sets the input number corresponding to the confirmed key information to 1 And stores it in the storage unit 130.

In addition, the control unit 150 checks the preset reference input count (step 510). Here, the reference input number is a reference value for automatically setting the deactivation key according to the number of times of input, which may be a user-set value directly set by the user or a default value set by default.

In step 520, the controller 150 confirms the key information input by the number of times lower than the reference input number based on the number of reference input times. That is, the controller 150 checks the key information input at a lower number of times than the reference input number in order to automatically deactivate the low-used key according to the frequency of key usage of the user. Here, if the user once inputs a specific key, the key is a key that the user can reuse according to the situation, so that the reference input number is preferably set to zero. That is, the control unit 150 checks key information that has never been used before.

The identified key information is stored as the deactivation key information in the storage unit 130 (step 530).

In other words, as described above, in the second embodiment, the key not used by the user is automatically deactivated based on the input frequency number of the remote controller 10, thereby preventing a situation that may occur due to the user's key input in advance can do.

Referring to FIG. 6, if the deactivation key setting of the remote controller is completed, the controller 150 periodically checks whether the infrared signal is received through the infrared receiver 140 (operation 600). That is, the controller 150 determines whether the user inputs a key for executing a specific function, a key for switching to a specific channel, a key for adjusting a volume level, or the like through the remote controller 10.

If the infrared signal received through the infrared receiver 140 exists, the controller 150 analyzes the received infrared signal to check the key information input by the current user in operation 610.

In step 620, the controller 150 determines whether the key information is the disabled key information. That is, the control unit 150 compares the confirmed key information with the deactivation key information stored in the storage unit 130 in advance. The controller 150 determines whether the key information matching the identified key information exists in the stored key information stored in the storage unit 130 as a result of the comparison.

If the received key information is the inactivated key information, the control unit 150 ignores the received infrared signal (step 630). That is, the operation corresponding to the received infrared signal is not performed and the previous operation state is maintained.

In step 640, the control unit 150 displays a message indicating that the operation corresponding to the received infrared signal is not performed and is ignored.

That is, as shown in FIG. 7, on one side of the display screen 700, a message indicating that the input key is a key set to be inactive based on the frequency of use and a message 710 prompting the user to input the desired key again are displayed .

In this case, unlike in the first embodiment, since the deactivation key is set regardless of the intention of the user in the second embodiment, the key actually input by the user may be set as the deactivation key.

Accordingly, after the message is displayed, the controller 150 determines whether the ignored infrared signal has been received again through the infrared receiver 140 (operation 650). That is, if the key input by the user is ignored, the user re-enters the desired key. Here, the re-input key may be the same key as the previously ignored key, or may be a different key than the input key. That is, if the previously input key is an erroneously input key, a new key will be input. If the input key is a normally input key, the input key will be re-entered.

Accordingly, if the ignored infrared signal is re-received, the controller 150 activates the key information corresponding to the re-received infrared signal (step 660). That is, the control unit 150 deletes the re-input key information from the deactivation key information previously stored in the storage unit 130. In other words, when the user continuously inputs the same key, it is highly likely that the input is a normal input rather than an input, so that the controller 150 activates the key when the deactivated key is continuously input.

Also, the controller 150 performs an operation corresponding to the re-received infrared signal (step 670).

If the determined key information is not the deactivated key information, the control unit 150 performs an operation corresponding to the received infrared signal (step 680).

As described above, according to the display device and the operation control method thereof according to the embodiment of the present invention, when a user does not need a plurality of keys provided in the remote controller, the user can easily use the remote controller by providing a simple remote controller setting function, It is possible to prevent the user from performing an undesired operation according to the wrong input of the remote control key by determining whether or not to perform the operation according to the key input from the remote control according to the frequency of use of the key.

In addition, according to the embodiment of the present invention, a more efficient and convenient use restriction function can be provided by selectively deactivating the input key for numeric keys for switching to a specific channel or switching to external input.
