The V-shaped portion 6252 basically provides pressure to a part of the main body 6210 so that the nose receiving portion 6250 forms a convex structure, and has a tendency to narrow the angle between the sides when there is no restriction from the outside. By the V-shaped portion 6252, the nose receiving portion 6250 may form a convex structure.

The technical features described in this embodiment can be applied to other embodiments, and those skilled in the art can modify it to fit other embodiments by demonstrating ordinary creative ability.

Hereinafter, a terminal device capable of extending a display according to another aspect of the disclosed embodiment will be described with reference to FIGS. 89 to 115 .

89 is a block diagram showing the configuration of a flexible terminal device according to an embodiment of the present invention. The terminal device 7100 of FIG. 89 is portable, such as a mobile phone, a smart phone, a PMP, a PDA, a tablet PC, a navigation system, and various types of portable devices equipped with a display function, as well as a monitor, a TV, a kiosk, etc. to be implemented as a stationary device. may be

Referring to FIG. 89 , the flexible terminal device 7100 includes all or part of a display unit 7110 , a sensing unit 7120 , and a control unit 7130 . However, before describing FIG. 89, a detailed configuration of the display unit 7110 and a method for detecting bending thereof will be described in detail.

90 is a view for explaining a basic structure of a display unit constituting a flexible terminal device according to an embodiment of the present invention. Referring to FIG. 90 , the display unit 7110 includes a substrate 7111 , a driving unit 7112 , a display panel 7113 , and a protective layer 7114 .

The flexible terminal device refers to a device that can be bent, bent, folded, or rolled like paper while maintaining the display characteristics of the existing flat terminal device. Accordingly, the flexible terminal device must be fabricated on a flexible substrate.

Specifically, the substrate 7111 may be implemented as a plastic substrate (eg, a polymer film) that can be deformed by external pressure.

The plastic substrate has a structure in which a barrier coating is treated on both sides of a base film. In the case of the base material, it may be implemented with various resins such as PI (Polyimide), PC (Polycarbonite), PET (Polyethyleneterephtalate), PES (Polyethersulfone), PEN (Polythylenenaphthalate), FRP (Fiber Reinforced Plastic), and the like. In addition, the barrier coating is performed on the surfaces opposite to each other in the base material, and an organic or inorganic film may be used to maintain flexibility.

Meanwhile, as the substrate 7111 , in addition to a plastic substrate, a material having flexible characteristics such as thin glass or metal foil may be used. The driving unit 7112 functions to drive the display panel 7113 . Specifically, the driver 7112 applies a driving voltage to a plurality of pixels constituting the display panel 7113, and may be implemented as an a-si TFT, a low temperature poly silicon (LTPS) TFT, or an organic TFT (OTFT). have. The driving unit 7112 may be implemented in various forms depending on the implementation form of the display panel 7113 . For example, the display panel 7113 may include an organic light emitting body including a plurality of pixel cells and electrode layers covering both surfaces of the organic light emitting body. In this case, the driver 7112 may include a plurality of transistors corresponding to each pixel cell of the display panel 7113 . The controller 7130 applies an electric signal to the gate of each transistor to emit light in the pixel cell connected to the transistor. Accordingly, an image may be displayed.

Alternatively, the display panel 7113 may be implemented as an EL, an electrophoretic display (EPD), an electrochromic display (ECD), a liquid crystal disply (LCD), an AMLCD, a plasma display panel (PDP), etc. in addition to the organic light emitting diode.

However, in the case of LCD, a separate backlight is required in that it cannot emit light by itself. For LCDs without backlight, ambient light is used. Therefore, in order to use the LCD display panel 7113 without a backlight, conditions such as an outdoor environment with a large amount of light must be satisfied.

The protective layer 7114 serves to protect the display panel 7113 . For example, a material such as ZrO, CeO2, or Th O2 may be used for the passivation layer 7114 . The protective layer 7114 may be manufactured in the form of a transparent film to cover the entire surface of the display panel 7113 .

Meanwhile, unlike shown in FIG. 90 , the display unit 7110 may be implemented with electronic paper. Electronic paper is a display in which the characteristics of general ink are applied to paper, and it is different from a general flat panel display in that it uses reflected light.

On the other hand, in the electronic paper, a picture or a character can be changed by using a twist ball or by electrophoresis using a capsule.

On the other hand, when the display unit 7110 is made of a transparent material, it may be implemented as a terminal device that is bendable and has a transparent property. For example, when the substrate 7111 is implemented with a polymer material such as plastic having a transparent property, the driver 7112 is implemented with a transparent transistor, and the display panel 7113 is implemented with a transparent organic light emitting layer and a transparent electrode, transparency is achieved. can have

The transparent transistor refers to a transistor manufactured by replacing the opaque silicon of the existing thin film transistor with a transparent material such as a transparent zinc oxide or titanium oxide. In addition, a new material such as indium tin oxide (ITO) or graphene may be used for the transparent electrode. Graphene refers to a material in which carbon atoms are connected to each other to form a honeycomb-shaped planar structure and have transparent properties. In addition, the transparent organic light emitting layer may be implemented with various materials. 91 to 93 are diagrams for explaining an example of a method for detecting shape deformation, that is, bending in a flexible terminal device according to an embodiment of the present invention.

The flexible terminal device 7100 may be bent by external pressure to deform its shape. The bending may include a case of normal bending, folding, and rolling. Normal bending refers to a state in which the flexible terminal device is bent, and the difference from folding and rolling is that the bent surfaces do not contact each other. have.

Folding refers to a state in which the flexible terminal device is folded. Folding and general bending may be classified according to the degree of bending. For example, when bending is performed over a certain radius of curvature, it is defined as a folded state, and when bending is performed below the radius of curvature, it can be defined as normal bending.

Rolling refers to a state in which the flexible terminal device is rolled up. Rolling may also be determined based on the radius of curvature. For example, a state in which bending over a certain radius of curvature is continuously detected over a certain area may be defined as rolling, and a state in which bending over a certain radius of curvature is detected in a relatively small area may be defined as folding. However, the definitions of the various shape modification examples as described above are only examples, and may be defined differently depending on the type, size, weight, characteristics, etc. of the flexible terminal device. For example, if the surface of the flexible terminal device 7100 is bendable enough to contact each other, folding may be defined as a state in which the surfaces of the flexible terminal device 7100 are in contact with each other at the same time as bending. On the other hand, rolling may be defined as a state in which the front and rear surfaces of the flexible terminal device are in contact with each other due to bending.

For convenience of description, in the present specification, these various types of bending and other bending forms are collectively referred to as bending. The flexible terminal device 7100 may detect bending in various ways.

For example, the sensing unit 7120 may include a bend sensor disposed on one surface, such as a front surface or a rear surface of the display unit 7110 , or a bend sensor disposed on both surfaces of the display unit 7110 . The controller 7130 may detect bending by using a value sensed by the bend sensor of the detector 7120 . Here, the bend sensor refers to a sensor that can be bent by itself and has a characteristic that a resistance value varies according to the degree of bending. The bend sensor may be implemented as a strain gauge. The strain gauge uses a metal or semiconductor whose resistance is greatly changed according to the magnitude of the applied force, and detects the deformation of the surface of the object to be measured according to the change in the resistance value. In general, a material such as a metal has a characteristic that the resistance value increases when the length increases according to an external force, and the resistance value decreases when the length decreases. Accordingly, it is possible to determine whether bending is performed by detecting a change in the resistance value.

The detection unit 7120 detects the resistance value of the bend sensor using the magnitude of the voltage applied to the bend sensor or the magnitude of the current flowing through the bend sensor, and the bending state at the position of the bend sensor according to the magnitude of the resistance value. can detect

91 shows a state in which the bend sensor is embedded in the front surface of the display unit 7110, this is only an example, and the bend sensor may be embedded in the rear surface of the display unit 7110 or may be embedded in both surfaces. . In addition, the shape, number, and arrangement position of the bend sensor may be variously changed.

91 illustrates an example in which a plurality of bar-shaped bend sensors are arranged in a horizontal direction and a vertical direction to form a grid. According to FIG. 91 , the bend sensor includes bend sensors 7021-1 to 7021-5 arranged in a first direction and bend sensors 7022-1 to 7022-5 arranged in a second direction perpendicular to the first direction. . Each of the bend sensors may be spaced apart from each other by a predetermined interval.

Although FIG. 91 shows that five bend sensors 7021-1 to 7021-5 and 7022-1 to 7022-5 are disposed in each of the horizontal and vertical directions, this is only an example, and may vary depending on the size of the flexible terminal device, etc. Of course, the number of bend sensors may be changed. As described above, since the bend sensors are disposed in the horizontal and vertical directions to detect bending in the entire area of the flexible terminal device, only a part of the device has a flexible characteristic or it is a device that needs to detect bending only in part. , the bend sensor may be disposed only in the corresponding portion.

Each of the bend sensors 7021-1 to 7021-5 and 7022-1 to 7022-5 may be implemented in the form of an electrical resistance sensor using electrical resistance or a micro optical fiber sensor using a strain rate of an optical fiber. Hereinafter, for convenience of description, it is assumed that the bend sensor is implemented as an electrical resistance type sensor.

Specifically, as shown in FIG. 92 , when the central region located at the center of the flexible terminal device 7100 is bent toward the downward direction with respect to both left and right edges of the flexible terminal device 7100, the band sensors ( 7021-1 to 7021-5). Accordingly, the resistance values of each of the bend sensors 7021-1 to 7021-5 arranged in the horizontal direction are changed. The sensing unit 7120 may detect a change in an output value output from each of the bend sensors 7021-1 to 7021-5 to detect that bending is performed in the horizontal direction based on the center of the display surface. 92 shows a state in which the central region is bent in a downward direction (hereinafter, referred to as Z-direction) with respect to the display surface, but in an upward direction (hereinafter referred to as Z+ direction) with respect to the display surface. Even in the case of bending to , it can be detected based on a change in output values of the bend sensors 7021-1 to 7021-5 in the horizontal direction.

In addition, when the shape of the flexible terminal device 7100 is bent so that the central region located at the center of the flexible terminal device 7100 faces upward as shown in FIG. 1 to 7022-5). The sensing unit 7120 may detect shape deformation in the vertical direction based on output values of the bend sensors 7022 - 1 to 7022 - 5 arranged in the vertical direction. Although bending in the Z+ direction is illustrated in FIG. 93 , it goes without saying that bending in the Z-direction can also be detected using the bend sensors 7022 - 1 to 7022 - 5 arranged in the vertical direction.

On the other hand, in the case of the shape deformation in the diagonal direction, since tension is applied to both the bend sensors arranged in the horizontal and vertical directions, the shape deformation in the diagonal direction can also be detected based on the output values of the bend sensors arranged in the horizontal and vertical directions. can

The terminal device according to an embodiment of the present invention is characterized in that the physical size of the screen can be freely adjusted.

Meanwhile, the first display unit may also be configured as a roll or flexible display.

In addition, the roll storage unit 7102 has an entrance and exit of the second display unit 7132 so that the screen is expanded by winding or unwinding the second display unit 7132 inside, and the roll storage unit 7102 . A spacing member 7201 having a predetermined thickness may be configured on both sides of the terminal body portion 7101 to correspond to the height of the terminal body portion 7101 .

The screen fixing means 7400 is composed of the same number of folding members 7410 as the number of the screen barrel described above, and each of the folding members 7410 is composed of a single wall or a double wall, and the folding members 7410 are A protrusion accommodating tube 7420 having a fixing protrusion 7440 is disposed therein. The fixing protrusion 7440 may have a curved round surface on one side and a vertically flat surface on the other side. Also, the distal end of the fixed selection unit 7430 may have an inclined surface.

In addition, fixing holes 7411 of a size through which a portion of the fixing protrusion 7440 can protrude are formed in each of the folding members 7410 .

The folding members 7410 are folded together with the folding of the screen barrel. A hole of a suitable size and a spring providing elasticity for pushing the fixing protrusion 7440 are configured.

If, in the state shown in FIG. 106, when the user rotates the protrusion accommodating tube 7420 from the outside, the fixing protrusion 7440 enters the folding member 7410, so that each fixing protrusion ( The coupling between the 7440 and the folding members 7410 is released. Accordingly, at this time, the user can extend or reduce the length of the screen barrel as desired.

However, when the user rotates the protrusion accommodating tube 7420 again to position the fixing protrusion 7440 to protrude out of the fixing hole 7411, that is, when the state as shown in FIG. 106 is reached, the screen is fixed Since the length of the means 7400 is in a state that does not change, the user eventually becomes in a state in which the operation of increasing the screen barrel to extend it or to reduce it to reduce it becomes impossible. That is, it is possible to prevent the length of the screen barrel from being changed during VR viewing.

On the other hand, a structure for rotating the protrusion receiving tube 7420 is shown in FIGS. 107 to 109 .

A fixed selection unit 7430 is configured at the lowest end of the folding member 7410 , and a user can selectively operate the fixed selection unit 7430 .

When the user rotates the fixed selector 7430, the protrusion receiving tube 7420 is rotated with the rotation of the fixed selector 7430, whereby the fixed protrusion ( The fixing protrusion 7440 that has passed through the fixing hole 7411 may be allowed to pass through the fixing hole 7411 to be fixed, or the fixing protrusion 7440 may be allowed to enter the inside of the folding member 7410 . In this case, the user can change the length of the screen barrel.

Conversely, when the user pushes the fixed selection part 7430 toward the protrusion accommodating pipe 7420, as shown in FIG. In a non-contact state, that is, the locking protrusion 7422 and the locking jaw 7431 are in a state in which they are not limited to each other. In this case, even when the user rotates the fixed selection unit 7430 , the protrusion receiving tube 7420 is not rotated together.

Therefore, depending on whether the user pushes or pulls the fixed selection part 7430, the projection accommodating tube 7420 may be rotated together with the rotation of the fixing selection part 7430, and this projection accommodating tube 7420 Ultimately, it is determined whether the length of the plurality of folding members 7410 can be varied through the rotation of .

Hereinafter, various embodiments that can utilize the virtual reality equipment according to the disclosed embodiment will be described in detail.

* As described above, in the embodiment described below, the virtual reality equipment is a computing device including at least one processor and a display, a device for viewing a virtual reality image displayed on the display, and viewing a virtual reality image with the computing device Devices of various types, such as a case including a case including at least one display and a device for viewing a virtual reality image, which is provided in a separate case to accommodate a computing device is used in the meaning of including all

For example, the methods of utilizing virtual reality equipment described below include at least one sensor included in a computing device or a case accommodating the computing device, and at least one processor included in the computing device or a case accommodating the computing device. It is performed by at least one of an application operating in , and an application operating in a server connected to the virtual reality equipment.

In this specification, virtual reality and virtual reality images are not limited to VR (Virtual Reality) and VR images, but virtual reality (VR, Virtual Reality) and virtual reality images, augmented reality (AR, Augmented Reality) and augmented reality images , includes both mixed reality (MR, Mixed Reality), mixed reality images, and general images, and is not limited thereto, and is used in the sense of including all kinds of images in which reality, virtual reality, and reality and virtual are mixed.

In addition, the virtual reality equipment described below or the server connected to the virtual reality equipment learns and operates using artificial intelligence, and the learning method described below can be applied to each embodiment. However, this is provided as an example, and the learning method applied or applicable to the disclosed embodiment is not limited to the content described below.

Artificial intelligence technology includes machine learning (machine learning) technology, and among machine learning technologies, it includes deep learning technology, which is widely used to analyze images.

Deep learning is a set of machine learning algorithms that attempt high-level abstractions (summarizing key contents or functions in large amounts of data or complex data) through a combination of several nonlinear transformation methods. Defined. Deep learning can be viewed as a field of machine learning that teaches computers to think in a broad framework.

When there is some data, it is represented in a form that a computer can understand (for example, in the case of an image, pixel information is expressed as a column vector), and many studies (how to do better) are presented to apply it to learning. How to make representations and how to build models to learn them) is underway. As a result of these efforts, various deep learning techniques have been developed. Examples of deep learning techniques include Deep Neural Networks (DNN), Convolutional Deep Neural Networks (CNN), Reccurent Neural Network (RNN), and Deep Belief Networks (DBN). have.

A deep neural network (DNN) is an artificial neural network (ANN) composed of a plurality of hidden layers between an input layer and an output layer.

117 is a diagram illustrating the structure of a deep neural network. Each circle in FIG. 117 represents one perceptron. A perceptron consists of several inputs, one processor, and one output value. The processor multiplies each input value by a weight, and then sums the input values multiplied by the weight. Then, the processor outputs one output value by substituting the summed value into the activation function. If a specific value is desired as the output value of the activation function, the weight multiplied by each input value may be corrected, and the output value may be recalculated using the modified weight. In FIG. 117 , each perceptron may use a different activation function. In addition, each perceptron receives the outputs from the previous layer as input, and then uses the activation function to obtain the output. The obtained output is transferred to the input of the next layer. Through the process as described above, some output values can be finally obtained.

Returning to the description of deep learning techniques, convolutional deep neural networks (CNNs) are a type of multilayer perceptrons designed to use minimal preprocessing. A convolutional neural network consists of one or several convolutional layers and general artificial neural network layers on top of it, and additionally utilizes weights and pooling layers. Thanks to this structure, the convolutional neural network can fully utilize the input data of the two-dimensional structure. In addition, convolutional neural networks can be trained via standard backpropagation. Convolutional neural networks are easier to train than other feed-forward neural network techniques and have the advantage of using fewer parameters.

A convolutional neural network extracts features from an input image by alternately performing convolution and subsampling on the input image. 118 is a diagram illustrating the structure of a convolutional neural network. Referring to FIG. 118, the convolutional neural network includes several convolution layers, several subsampling layers (Subsampling layer, Lacal pooling layer, Max-Pooling layer), and a fully connected layer. . The convolution layer is a layer that performs convolution on an input image. In addition, the subsampling layer is a layer that locally extracts the maximum value from the input image and maps it to a 2D image, and subsampling is performed by enlarging the local area.

In the convolution layer, information such as the kernel size, the number of kernels to be used (ie, the number of maps to be created), and a weight table to be applied during the convolution operation are required. For example, suppose that the size of the input image is 32x32, the size of the kernel is 5x5, and the number of kernels to be used is 20. In this case, if a 5×5 kernel is applied to a 32×32 input image, it is impossible to apply the kernel to two pixels above, below, left, and right of the input image. Because, as can be seen from the convolution calculation process shown in FIG. 119 , when a kernel is placed on the input image and then convolution is performed, the result value of '-8' is a kernel among pixels of the input image included in the kernel. This is because it is determined by the value of the pixel corresponding to the center element of . Therefore, when convolution is performed by applying a 5×5 kernel to a 32×32 input image, a 28×28 map is generated. Previously, since it was assumed that the total number of kernels to be used is 20, in the first convolutional layer (refer to 'C1-layer' in FIG. 7 ), a total of 20 maps with a size of 28×28 are generated.

In the subsampling layer, information on the size of a kernel to be subsampled and information on whether to select a maximum value or a minimum value among values in the kernel region are required. 120 is a diagram illustrating a subsampling process. Referring to FIG. 120 , it can be seen that the size of the kernel to be subsampled is 2×2 and is set to select the maximum value among the values included in the kernel area. If a 2×2 kernel is applied to an 8×8 input image, a 4×4 output image can be obtained. That is, it is possible to obtain an output image reduced in size to 1/2 compared to the input image.

Returning to the description of the deep learning technique, a Reccurent Neural Network (RNN) refers to a neural network in which connections between units constituting an artificial neural network constitute a directed cycle. Unlike forward neural networks, recurrent neural networks can utilize the memory inside the neural network to process arbitrary inputs.

Deep Belief Networks (DBN) is a generative graphical model used in machine learning, and in deep learning, it means a deep neural network composed of multiple layers of latent variables. There is a connection between layers, but there is no connection between units within a layer.

The deep trust neural network can be used for prior learning due to the nature of the generative model, and after learning the initial weights through prior learning, the weights can be fine-tuned through backpropagation or other discrimination algorithms. This characteristic is very useful when the training data is small, because the smaller the training data, the stronger the influence of the initial value of the weight on the resulting model. The pre-learned initial weight value is closer to the optimal weight compared to the arbitrarily set initial weight value, which enables performance and speed improvement in the fine-tuning stage.

In an embodiment, the virtual reality equipment may be used to control an external device including at least one power unit.

For example, virtual reality equipment may be used to control robots (including robots that move on land, underwater, and in the air), RC cars, drones, and the like. At least one camera is provided in an external device including a robot, an RC car, and a drone, and a user can view an image captured by the external device using virtual reality equipment and transmit a control command to the external device.

A method for the virtual reality equipment to obtain a control command from a user and transmit it to an external device will be described in detail below, and all possible means other than the contents described below may be used.

For example, a user may control a drone using virtual reality equipment, and may also perform various controls using additional parts provided in the drone. For example, the drone is equipped with additional parts for spraying pesticides, the user controls the drone and determines the location to spray the pesticide based on the image received from the drone, and transmits the pesticide spray command to the drone to spray the pesticide can do.

There are various methods for the virtual reality equipment to obtain a command for manipulation from a user, but for example, the following embodiments may be applied.

For example, the virtual reality device may acquire a command for controlling an external device by recognizing the user's finger movement and the shape of the finger. In addition, the virtual reality equipment may acquire a user input by recognizing the user's voice, recognizing the pupil movement of the user using a camera provided in the virtual reality equipment, or recognizing the user's head movement.

In an embodiment, the virtual reality device may recognize a user's fingernail further than finger recognition.
