On the other hand, as described above, when the transparent display 121 and the touch pad are configured as a touch screen by forming a mutual layer structure, the transparent display 121 may be used as an input device in addition to an output device. The transparent display 121 includes a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, and a three-dimensional display ( 3D display). In addition, two or more transparent displays 121 may be present depending on the implementation form of the information providing vehicle 100. For example, the transparent display 121 may be present in the front windshield, the side windshield, and the rear windshield of the vehicle 100.

The sound output module 122 outputs audio data received from the communication unit 114 or stored in a memory (not shown). In addition, the sound output module 122 outputs sound signals related to functions (destination voice guidance, traffic situation voice guidance, etc.) performed in the information providing vehicle 100. The sound output module 122 may include a speaker, a buzzer, and the like.

The alarm unit 123 outputs a signal for notifying the occurrence of an event in the information providing vehicle 100. Examples of events occurring in the information providing vehicle 100 may include an occurrence of a defect in the vehicle, reception of accident information of another vehicle, and a situation of insufficient fuel. The alarm unit 123 may output a signal for notifying the occurrence of an event in a form other than an audio signal or a video signal. For example, a signal can be output in the form of vibration.

The control unit 130 usually controls the overall operation of the information providing vehicle 100. That is, the control unit 130 may overall control the situation recognition unit 110, the image processing unit 120, and the output unit 120. For example, the controller 130 may determine a display mode for displaying an object corresponding to the external vehicle, based on the context information of the external vehicle. At this time, the display mode may include an augmented reality mode and a map mode.

Meanwhile, the image processing unit 120 according to an embodiment of the present invention may generate an image corresponding to context information by mapping it on a map.

The controller 130 may adjust the transparency of the transparent display 121 based on the illumination information outside the vehicle. For example, the controller 130 may lower the transparency of the transparent display 121 when the illumination is high (bright day) and increase the transparency of the transparent display 121 when the illumination is low (dark day). In addition, the control unit 130 may adjust the transparency differently for each position of the transparent display 121. Meanwhile, when the transparency in the transparent display 121 is not uniform, the controller 130 may give a gradation for natural expression.

Since the transparent display 121 is composed of a transparent element, the control unit 130 controls the transparency of the transparent display 121 by adjusting the light transmittance of the transparent element or the RGB value of each pixel by adjusting the RGB value of each pixel. Transparency can be adjusted.

According to an embodiment of the present invention, the controller 130 may adjust the transparency of the transparent display 121 based on the illumination information according to the driver's gaze direction. For example, when the driver is driving facing the sun, the controller 130 lowers the transparency of the transparent display 121, and when the driver is driving with the sun behind his back, the controller 130 is the transparent display 121 Can increase the transparency.

On the other hand, in the case of a transparent display 121 in the form of an organic light-emitting diode (Organic Light-emitting diode) and a liquid crystal display (Liquid Crystal Display), the control unit 130, the transparent display 121, such as a transparent glass in the normal While maintaining the state, by supplying power to the transparent display 121, the liquid crystal display may block light, and the transparent display 202 may be set to an opaque state.

The transparent display 121 may be implemented in various forms such as a transparent liquid crystal display (LCD) type, a transparent thin-film electroluminescent panel (TFEL) type, a transparent OLED type, and a projection type. Hereinafter, various embodiments of the structure of the transparent display 121 will be described.

The transparent LCD type means a transparent display implemented by removing a backlight unit from a currently used LCD device and using a pair of polarizers, optical films, transparent thin film transistors, and transparent electrodes. The transparent LCD device has a disadvantage in that a polarizing plate or an optical film is used to have low transparency, and light efficiency is low by using ambient light instead of a backlight unit, but there is an advantage of realizing a large area transparent display.

The transparent TFEL type means a device using an AC type inorganic thin film EL display (AC-TFEL) composed of a transparent electrode, an inorganic phosphor, and an insulating film. AC-TFEL is a display that excites the phosphor and emits light as the accelerated electrons pass inside the inorganic phosphor. When the transparent display 121 is implemented in the form of a transparent TFEL, the control unit 130 may determine an information display position by adjusting the electron to be projected to an appropriate position. Since the inorganic phosphor and the insulating film have transparent properties, a very transparent display can be realized.

In addition, the transparent OLED type means a transparent display using an OLED capable of self-emission. Since the organic light emitting layer is transparent, if both electrodes are used as transparent electrodes, it can be realized as a transparent display device. OLEDs emit light when electrons and holes are injected from both sides of the organic light emitting layer and they are combined in the organic light emitting layer. The transparent OLED device displays information by injecting electrons and holes into a desired position using this principle.

3B is a view showing a detailed configuration example of a transparent display implemented with a transparent OLED type. For convenience of description, reference numeral 131 is given to a transparent display implemented in a transparent organic light-emitting diodes (OLED) type.

According to FIG. 3B, the transparent display 121 includes a transparent substrate 121-1, a transparent transistor layer 121-2, a first transparent electrode 121-3, and a transparent organic light-emitting layer. (121-4), the second transparent electrode (121-5), and includes a connecting electrode (121-6).

The transparent substrate 121-1 may be made of glass or a polymer material such as plastic having transparent properties. The material of the transparent substrate 121-1 may be determined according to the environment in which the transparent display 121 is applied. For example, the polymer material has the advantage of being lightweight and flexible, and thus can be used in a portable display device, and glass can be used in a shop's show window or a general window.

The transparent transistor layer 121-2 means a layer including a transistor manufactured by replacing the opaque silicon of the existing thin film transistor with a transparent material such as transparent zinc oxide or titanium oxide. A source, a gate, a drain, and various dielectric films 121-7 and 121-8 are provided in the transparent transistor layer 121-2, and a connection electrode electrically connecting the drain and the first transparent electrode 121-3 ( 121-6) can also be provided. In FIG. 3B, only one transparent transistor including source, gate, and drain is illustrated in the transparent transistor layer 121-2, but a plurality of transparent transistors evenly distributed over the entire area of the display surface is provided. The controller 130 may apply a control signal to the gates of the respective transistors in the transparent transistor layer 121-2 to drive the transparent transistor to display information.

The first transparent electrode 121-3 and the second transparent electrode 121-5 are disposed in opposite directions based on the transparent organic light emitting layer 121-4. The first transparent electrode 121-3, the transparent organic light emitting layer 121-4, and the second transparent electrode 121-5 form organic light-emitting diodes.

Transparent organic light emitting diodes are largely classified into a passive matrix OLED and an active matrix OLED according to a driving method. PMOLED is a structure in which a portion where the first and second transparent electrodes 121-3 and 121-5 cross each other forms a pixel. On the other hand, AMOLED has a structure in which a thin film transistor (TFT) for driving each pixel is provided. 3B shows the active type.

The first transparent electrode 121-3 and the second transparent electrode 121-5 each include a plurality of line electrodes, and alignment directions of the line electrodes are formed perpendicular to each other. For example, if the line electrodes of the first transparent electrode 121-3 are arranged in the horizontal direction, the line electrodes of the second transparent electrode 121-5 are arranged in the vertical direction. Accordingly, a plurality of crossing regions are formed between the first transparent electrode 121-3 and the second transparent electrode 121-5. A transparent transistor is connected to each crossing region as shown in FIG. 3B.

The control unit 130 allows a potential difference to be formed for each crossing region using a transparent transistor. Electrons and holes are introduced into the transparent organic light emitting layer 121-4 from each electrode in the crossing region where the potential difference is formed, and light is emitted while bonding. On the other hand, the crossing area where no potential difference is formed does not emit light, and accordingly, the rear background is transparently reflected.

Indium tin oxide (ITO) may be used as the first and second transparent electrodes 121-3 and 121-5. Alternatively, new materials such as graphene may be used. Graphene refers to a material having transparent properties with a carbon atom connected to each other to form a honeycomb plane. In addition, the transparent organic light emitting layer 121-4 may also be implemented with various materials.

On the other hand, as described above, the transparent display 121 may be implemented in a projection type in addition to a transparent liquid crystal display (LCD) type, a transparent thin-film electroluminescent panel (TFEL) type, and a transparent OLED type. The projection type means a method of projecting and displaying an image on a transparent screen such as a HUD (Head Up Display).

According to an embodiment of the present invention, the preset distance may include a visible distance through which a driver can see an external vehicle with the naked eye. The information providing vehicle 100 may set in advance the visible distance that drivers can see on the outside on average as a criterion for determining the display mode. Meanwhile, the information providing vehicle 100 may be set by changing a visible distance according to at least one of weather information, illuminance information, and humidity information. For example, in the case of rain or low illumination, the information providing vehicle 100 may set the visible distance shorter than the average visible distance.

In operation 560, when the distance between the external vehicles is greater than or equal to a preset distance, the information providing vehicle 100 may determine the display mode as the map mode. For example, when an external vehicle exists at a non-visible distance where a user cannot see the external vehicle with the naked eye, the information providing vehicle 100 may determine the display mode as the map mode.

In step 570, the information providing vehicle 100 may map an object corresponding to the external vehicle on the map and display it on the transparent display 121. Meanwhile, the information providing vehicle 100 may change the scale of the map based on the distance between the information providing vehicle 100 and the external vehicle. For example, the information providing vehicle 100 maps and displays an object corresponding to an external vehicle on a large-scale map (detailed map) as the distance from the external vehicle is closer, and the smaller the distance, the smaller the distance. Objects corresponding to an external vehicle may be mapped and displayed on a map (a briefly shown map). With reference to 11, it will be described in more detail later.
