4 is a diagram illustrating an embodiment in which an image of the display unit 241 is switched by a user's breath.

4 illustrates an embodiment in which the display device 200 is mounted on the refrigerator 100.

As shown in FIG. 4A, when the user blows his breath on the display unit 241 of the display apparatus 200, the screen of the display unit 241 may be switched. More specifically, when the sensor 300 detects the user's breath, the control unit 280 allows the second image 18 to be superimposed and displayed on the background screen of the display unit 241 having the first image 17. Can be controlled.

The first image 17 may be a background screen before the user blows his breath. The first image may be an image in which a plurality of icons capable of operating various functions of the refrigerator 100 are displayed. In addition, when the user selects a corresponding icon, it may mean a background screen on which a command corresponding to the icon is executed and related content can be provided.

When the user blows, the sensor 300 detects the user's breath.

In order to detect the user's breath, a sensor 300 for detecting various stimuli may be used. For example, it may be configured as a microphone for detecting the user's breathing sound. It is preferable that the microphone is provided to detect the frequency of a sound range generated by the user's breath.

In addition, the sensor 300 may include a humidity sensor 300 capable of detecting a change in humidity increased by breathing, and a temperature sensor 300 for detecting an increase in air temperature by breathing.

Meanwhile, the sensor 300 may be provided on one side of the display unit 241. It is preferable that the sensor 300 is located under the display device 200 so that the sensor 300 can operate well even with the breath of a user with a small height.

As shown in FIG. 4(b), when the sensor 300 detects the user's breath, the control unit 280 superimposes a second image having a predetermined transparency on the first image of the display unit 241 Can be displayed.

In more detail, the controller 280 may control the first image 17 to be displayed in a form where the second image 18 is slightly covered. To this end, the transparency of the second image 18 is adjusted by the control unit 280.

In particular, the transparency of the second image 18 may be controlled to be changed according to the number of times, time, or period of breathing by the user.

For example, if the time for the user to breathe increases, the controller 280 may gradually lower the transparency of the second image 18. Here, an image with high transparency has a greater degree of transparency than an image with low transparency.

As shown in FIG. 4(b), the second image 18 is superimposed on the first image 17 with a predetermined transparency in the initial stage of blowing the user's breath. The transparency of the second image 18 decreases as the number or time of the user blowing his breath increases.

When a user blows his breath for a certain period of time or more than a certain number of times, the controller 280 may display only the second image 18 on the display unit 241 as shown in FIG. 4C. That is, as the time or the number of times the user blows his breath increases, the transparency of the second image may gradually approach zero.

That is, the display unit 241 is preferably expressed so that the first image 17 is gradually changed to the second image 18 by the stimulus of the user's breath.

In addition, only a simple input is needed to blow the breath "after" without having to go through various complicated processes. Therefore, since the screen of the display unit 241 can be controlled by a simple user's input, it is easy to use.

Meanwhile, the second image 18 may be set so that a natural reaction that can be intuitively predicted according to the user's breath is reflected on the display unit 241.

Specifically, it can be easily reminiscent that when a user blows his breath on a window, steam is formed on the window. In this way, the control unit 280 may control the second image 18 so that natural reactions commonly seen in daily life can be realized in the display.

That is, when the sensor 300 detects the user's breath, the control unit 280 may display the second image 18 that is steamed on the glass window by overlapping the first image 17.

In addition, the user can expect that the degree of fogging on the window pane will increase as the time to blow the breath increases. It is preferable that the control unit 280 allows such an emotional part to be reflected on the display unit 241 as it is.

Accordingly, the control unit 280 may additionally overlap and display an image in which the degree of fogging on the glass window is increased depending on the time or number of times the user blows the breath.

According to an embodiment of the present invention, the second image 18 may be an image related to weather information or seasonal information. To this end, the communication unit 210 may receive weather or season information from an external server. In addition, the controller 280 may display the second image 18 to be an image corresponding to the received information.

For example, when the received seasonal information is at least one of spring, summer, autumn, winter, rainy season, and dry season, the second image 18 may be an image that can symbolize or represent the season.

The image representing the seasonal information may be an image of a flower blooming in each season or an image of seasonal fruits. In addition, the second image 18 is preferably an image that can easily recall typical seasons such as an image of a cool sea or ice in summer, an image of fallen leaves or autumn leaves in autumn, and snow and frost in winter.

Similarly, the weather information received by the communication unit 210 may be various types of information about the weather, such as rain, snow, wind, cloudy, sunny, typhoon, rainy season, or heatwave. In addition, the controller 280 may display a second image 18 that can symbolize or represent the weather.

For example, the second image 18 on a rainy day may be an image of water droplets formed on a window. On a snowy day, an image of snow on the window can be used.

It goes without saying that the type of the second image 18 corresponding to season or weather information that can be received and classified by the communication unit 210 is not limited to the above-described embodiment.

5 is a diagram illustrating a state in which a user's touch input is displayed on the second image 18. The display device 200 may include a recognition unit 282 for recognizing a commercial user's touch input to the display unit 241.

That is, the recognition unit 282 detects a user's touch input.

In some cases, you can leave a picture or text with your finger on a window that is steamed by the user's breath. This is because, as the condensed water droplets are removed from the window, only the area where the finger has passed becomes transparent. It is preferable that the control unit 280 reflects such an intuitive experience on the display device 200.

Accordingly, the controller 280 may control to display the touch input content on the second image 18. In particular, according to an embodiment of the present invention, the control unit 280 may express the second image 18 as if it changes transparently with respect to the touch input area.

Since the second image is displayed by being superimposed on the first image, when a user makes a touch input, the second image may be expressed to be deleted only in the touch input area among the second images superimposed on the first image. The first image may be reflected or projected on an area deleted from the second image.

That is, when there is fog on the window, the scenery outside the window is not visible, but when the user touches the fogged portion with a finger, the condensed water droplets are removed from the portion where the finger passes. When the condensed water droplets are removed, the scenery outside the window can be seen through the part where the finger passed. When the user touches the second image by reflecting this phenomenon as it is, the touched part may be displayed transparently, and the existing first image may be reflected again in the transparently displayed part.

Instead of simply entering standard text, users can directly input simple information using their fingers as desired. The image or text information drawn directly using the user's handwriting can effectively satisfy the user's desire to deliver an emotional message.

In addition, it is possible to provide a feeling that the display unit 241, which used only to transmit information, can be changed into a canvas or letter paper by a simple action of a user. This can give users enjoyment even in an emotional aspect.

In addition, the concept of drawing a letter or a picture on it after breathing is something that the user has intuitively experienced in real life, so it can not only stimulate the user's sensibility, but also provide convenience and freshness.

Meanwhile, the touch input may be an indirect touch or a direct touch.

6 is a diagram illustrating a display unit 241 according to an embodiment of the present invention. Fig. 6(a), which is an existing background screen, shows the background screen before the user blows his breath.

6(b) shows that when the user blows, the sensor 300 detects the sound of the user's breath, and the control unit 280 is a second image having a predetermined transparency in the first image of the display unit 241 The steps of superimposing are shown.

Since the communication unit 210 may receive weather or season information from an external server, a frosty image as shown in FIG. 6 may be displayed when weather information such as snowy weather or midwinter is received.

Fig. 6(c) shows a step of displaying the contents of the user's touch input on the second image after blowing enough breath.

7 is a diagram illustrating a state in which a screen on which the user's touch input is displayed is transmitted to an external communication terminal 400.

When input information is displayed on the display unit 241 by the controller 280 by a user's touch, the communication unit 210 may transmit the screen of the display unit 241 to the external communication terminal 400.

That is, a screen viewable on the display device 200 may be transmitted to the external communication terminal 400 connected through a network network. The external communication terminal 400 may be a personal computer, a mobile phone, or various electronic products to which the display device 200 may be installed.

Meanwhile, the controller 280 may display an icon 261 for setting a recipient for selecting an object to receive the screen of the display unit 241 on the screen of the display unit 241.

The receiver setting icon 261 may be controlled to appear on the second image 18 when the user wants to transmit the screen of the display unit 241 to the external communication terminal 400.

When the receiver setting icon 261 is selected, the control unit 280 may provide data storing an ID number or a phone number of the external communication terminal 400. The user may select the recipient to whom the user wants to send the memo by selecting the recipient setting icon 261. Then, the communication unit 210 transmits the second image 18 on which the user's touch input is displayed to the receiver.

Accordingly, it is possible to transmit emotional information to a remote recipient through the display device 200. Therefore, the present invention can be used more usefully than the case of applying the display device 200 to a home appliance or communication terminal that users usually use.

For example, when the display device 200 is installed on the door of the refrigerator 100, it is possible to take notes about necessary items at that time while using the refrigerator 100 through the display device 200. At this time, a difficult operation method is not required, but the purpose can be achieved only by blowing a breath and drawing a note by hand.

In addition, since the memo can be transmitted to any external communication terminal 400, a home appliance that simply performs a refrigeration function can also perform the role of a communication terminal.

That is, the control unit 280 controls so that an emotional and immediate reaction by a simple act of blowing a breath can be reflected on the display unit 241. When the recognition unit 282 recognizes the user's breath, the control unit 280 provides a basis for displaying the user's touch input on the display unit 241.

In addition, the control unit 280 may transmit the screen of the display unit 241 into which the information is input to the external communication terminal 400 by the user's selection. All of these processes are based on everyday activities, such as painting a picture with a finger on a window. Accordingly, people such as children, the elderly, and children with intellectual disabilities who are not familiar with difficult device operation can easily use the present invention.
