Of course, those skilled in the art will appreciate that the foregoing is by way of example only, and that other existing or future devices, which may be suitable for use in the present application, are also encompassed within the scope of the present application and are hereby incorporated by reference.

In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

The following describes in detail an information display method provided by the present application, taking an information display apparatus for presenting information to a user as an example.

Referring to fig. 2, according to an aspect of the present application, there is provided an information display method including steps S11 and S12. In step S11, the information display device detects the side of the user relative to the display screen in the information display device; in step S12, the information display apparatus displays information through the display screen in a manner directed to the local side.

Specifically, in step S11, the information display apparatus detects the side of the user with respect to the display screen in the information display apparatus. For example, the information display device includes a display screen having front and back sides and capable of presenting contents such as graphics, text, and the like on the front and back sides. Wherein it may first be detected on which side the user is located in relation to the display screen in order to present the content to the user in the correct way. For example, in some embodiments, which side of the display screen the user is active on is detected by various known sensors (e.g., including, but not limited to, ultrasonic sensors, pyroelectric infrared sensors, human proximity sensors, sound sensors, image sensors, etc.); or when a touch input device (for example, including but not limited to a touch film based on the projected capacitance principle) attached to the side of the display screen detects a touch operation, determining that the user is located at the corresponding side of the display screen; or when an external input device (e.g., including but not limited to a keyboard, a touchpad, a motion sensing device, etc.) located on one side of the display screen detects an input, it is determined that the user is located on the corresponding side of the display screen.

Of course, those skilled in the art will appreciate that the above-described sensors, touch input devices, and external input devices are merely examples, and that other existing or future devices or devices may be used, if applicable, within the scope of the present application and are hereby incorporated by reference. For example, the presence of a heat source, and thus a human body, is detected by an infrared sensor; or detecting the picture change or performing image recognition through a camera so as to detect the position of the user; or by detecting that a physical key provided on the same side of the display screen is pressed, thereby determining that the user is located on that side.

In step S12, the information display apparatus displays information through the display screen in a manner directed to the local side. For example, still taking the scenario shown in fig. 1 as an example, when the information display device detects that the user is located on the left side of the transparent display 101 through the camera (or the image sensor), the graphics, text, and the like that need to be presented to the user are displayed in a manner of facing to the left side, the information displayed on the transparent display 101 is facing to the user, and the graphics, text, and the like viewed by the user are displayed in a forward direction. Accordingly, if the information display apparatus detects that the user is located on the right side of the transparent display 101, information that needs to be displayed is displayed to the right side. Referring to the touch input panel shown in fig. 3, the main component of the touch input panel is an OLED touch display panel, which can perform double-sided display and double-sided touch. With reference to fig. 3, if the left side is the front side and the right side is the back side, when the user performs an operation on the left side, for example, the user points to click on the touch input panel, the content displayed on the touch input panel is as shown in fig. 3, a control button is displayed on the touch input panel, and the control button is marked with a "start" character; other information such as weather information is displayed below the control button. When the user performs touch input on the reverse side, the touch input panel horizontally inverts the display content, so that the content seen by the user on the reverse side is also the display content shown in fig. 3.

The information display device further comprises a peripheral circuit connected with the display screen, such as a driving circuit for driving the display screen to emit light and/or display information. The display screen has two sides for displaying information on a desired side, and may be an OLED display panel, a transparent liquid crystal display, a glass panel embedded with an LED light source, a double-sided projection device, a combination of two single-sided display screens facing away from each other, etc., and these display screens are only examples, and other existing or future display screens may be applicable to the present application, and are also included in the scope of the present application and are incorporated herein by reference.

Preferably, the display screen comprises a transparent display screen. Wherein, transparent display screen has two sides, can be in the simultaneous display information of two sides, like OLED display screen, transparent liquid crystal display screen etc.. Referring to fig. 4, which shows an exemplary operation state of the transparent display, a user can see an object on the other side of the display through a portion of the display where information is not displayed, in addition to information displayed on the display itself. After detecting that the side of the user relative to the transparent display screen is located, the information display device displays the information in a mode of facing the side for the user on the side to watch; and when the user moves to the other side of the transparent display screen, the display content is turned over for the user at the other side to watch. In the process of changing the display mode of the transparent display screen, the transparent display screen does not need to move or turn over, and the display information watched on the two sides of the transparent display screen is displayed on the same transparent display panel, so that the space occupied by the display screen can be saved.

Preferably, the display screen further comprises two touch input devices respectively attached to two sides of the transparent display screen. With the development of the times, touch technologies have been widely applied to human-computer interaction processes from mobile devices to public terminals. Among them, the touch device generally includes: 1) input devices that can monitor a touch operation or a touch position of a finger or other parts of the body, such as capacitive devices, resistive devices, infrared devices, and the like; 2) examples of Display devices for displaying information include a CRT (Cathode Ray Tube), an LED (Liquid Crystal Display), and the like. When input operation is required to be performed through the touch device, a graphical or text interface is usually displayed by the display device, a user performs input operation through the input device, and in some cases, the display device can perform feedback on the input operation of the user.

For example, referring to fig. 5, a first touch layer 104 and a second touch layer 105 are respectively disposed on the glass surfaces of both sides of the transparent display 101. In some embodiments, the first touch layer 104 and the second touch layer 105 are transparent metal oxide (e.g., ITO, indium tin oxide) conductor layers that form a capacitive touch film; the two conductor layers are used as touch input devices. Each conductor layer is provided on four sides with elongated electrodes for forming a low voltage alternating electric field in the conductor layer. When a user A touches or approaches the conductor layer by a finger, a coupling capacitor is formed between the finger and the conductor layer, currents emitted by the four-side electrodes flow to the contact points, the magnitude of the currents is in direct proportion to the distance from the finger to the electrodes, and the position of a touch point of the user finger on the conductor layer can be calculated according to the magnitudes of the currents. In order to protect the conductor layer, protective glass can be added outside the conductor layer. At this time, the two conductor layers are combined with the transparent display screen 101 to form a capacitive touch screen.

In other embodiments, the touch input device may further include (but is not limited to):

1) the resistance touch film is attached to the surface of the transparent display screen and used for sensing pressure, and the resistance touch film and the transparent display screen are combined to form a resistance type touch screen; the film takes a layer of glass or hard plastic flat plate as a base layer, the surface of the glass or hard plastic flat plate is coated with a transparent metal oxide conducting layer, a plastic layer is covered, the inner surface of the plastic layer is also coated with a transparent metal oxide conducting layer, tiny (less than 1/1000 inches) transparent isolation points are arranged between the two metal oxide conducting layers, the two conducting layers are separated by the isolation points, when a finger touches a screen, the two conducting layers are contacted at the position of a touch point, and the position of the touch point can be calculated by calculating the resistance between the contact point and other parts of the conducting layers;

2) the infrared transmitting and receiving sensing elements are arranged at the edges of the two sides of the transparent display screen and are combined with the transparent display screen to form an infrared touch screen; forming an infrared detection network on the surface of the transparent touch screen, and determining the position of a touch point of a user by detecting the position of the blocked infrared;

3) the ultrasonic wave transmitter and the ultrasonic wave receiver are arranged on two sides of the transparent display screen and combined with the transparent display screen to form a surface acoustic wave touch screen; determining the position of a touch point of a user by detecting attenuation of the sound wave after the sound wave meets the blockage;

4) the physical operation keys are arranged on two sides of the transparent display screen and combined with the transparent display screen to form a human-computer interaction interface; the position of the touch point of the user is determined by detecting the key operation of the user, for example, by detecting the current change generated by the key operation.

Of course, those skilled in the art should understand that the above-mentioned touch input device is only an example, and other existing or future touch input devices may be applicable to the present application, and are included in the scope of the present application and are incorporated herein by reference. For example, a touch input device includes two pieces of laminated glass with a transparent metal oxide conductive coating in between, and an ac signal is applied to the conductive coating to form an electrostatic field on the screen surface; when a finger (without wearing gloves) or other conductor contacts the sensor, the electrostatic field is disturbed; the matched image processing controller detects the interference signal and the position thereof, thereby determining the position of the touch point; the laminated glass and the image processing controller form an NFI (Near Field Imaging) touch device, and the touch input device and the transparent display screen are combined to form an NFI (Near Field Imaging) touch screen.

Preferably, referring to fig. 6, in step S11, when the information display device detects a touch operation of a user on a display screen of the device, the side of the user opposite to the display screen is determined by detecting whether human bodies exist on two sides of the display screen. For example, still referring to fig. 5, when it is detected that the user a performs a touch operation on the first touch layer 104 or the second touch layer 105 attached to the surface of the transparent display screen 101, the position of the user a is detected by sensors (for example, including but not limited to an ultrasonic sensor, a pyroelectric infrared sensor, a human body proximity sensor, a sound sensor, and an image sensor) distributed at two sides of the transparent display screen 101; at this time, with respect to the transparent display 101, the sensor located at the side where the first touch layer 104 is located detects a human body (i.e., the user a), and the sensor located at the side where the second touch layer 105 is located does not detect a human body. Therefore, the information display apparatus determines that the user a is located on the side of the first touch layer 104 with respect to the transparent display screen 101, and displays information to be displayed through the transparent display screen 101 in a manner facing the side of the first touch layer 104, that is, in a manner facing the user a.

In other embodiments, when the information display device detects a touch operation of a user on a display screen of the device, the information display device may further determine the side of the user relative to the display screen according to the touch position of the user on the touch input device. For example, still referring to fig. 5, when the information display device detects that there is a touch operation on the first touch layer 104, that is, the touch position of the user a is located on the first touch layer 104; while no touch operation on the second touch layer 105 is detected. Therefore, the information display apparatus determines that the user a is located on the side of the first touch layer 104 with respect to the transparent display screen 101, and displays information to be displayed through the transparent display screen 101 in a manner facing the side of the first touch layer 104, that is, in a manner facing the user a.

A display direction control flow of a typical information display device is shown in fig. 7, where the information display device monitors a touch input of a user on a transparent display screen with a touch layer, determines an input direction of the touch input of the user relative to the transparent display screen according to the touch input of the user or by using other input devices, sensors, and the like once the touch input of the user is detected, compares the input direction with a current display direction of information on the transparent display screen, and determines whether the input direction and the current display direction are the same. When the two are consistent, namely the presenting direction of the information on the current transparent display screen is towards the user, continuing to monitor the next touch input of the user; and when the two are not consistent, namely the presenting direction of the information on the current transparent display screen is opposite to the user, adjusting the presenting direction of the information and changing the presenting direction of the information to be towards the user.

Preferably, the determining that the user is located on the side opposite to the display screen by detecting whether human bodies exist on two sides of the display screen comprises: 1) if the fact that a human body exists on only one side of the display screen is detected, the side of the display screen is used as the side, relative to the display screen, of the user; or: 2) and if the human bodies are detected to exist on both sides of the display screen, preferably selecting one side from the both sides of the display screen as the side of the user relative to the display screen.

For example, still referring to fig. 5, with respect to the transparent display 101, when the information display apparatus detects a human body only on the side where the first touch layer 104 is located and does not detect a human body on the side where the second touch layer 105 is located, thereby determining that the user a is present only on the side of the first touch layer 104, information to be displayed is displayed in a manner facing the side where the first touch layer 104 is located (i.e., the side where the user a is located). Or, for example, when the information display device detects a human body on both the side where the first touch layer 104 is located and the side where the second touch layer 105 is located, the information display device determines one side from the two sides as the direction in which information is presented according to a preset rule.

Wherein, preferably, a preferred side of the display screen satisfies at least any one of the following: 1) a human body on the preferred side of the display screen has a touch action; 2) the distance between the human body on the preferred side of the display screen and the display screen is smaller than or equal to a preset distance threshold value; 3) the distance between the human body on the preferable side of the display screen and the display screen is smaller than the distance between the human body on the other side of the display screen and the display screen.

For example, still referring to FIG. 5, relative to transparent display 101, when the information display device is only touching at the first touchThe side on which the layer 104 is located detects a human body, and the side on which the second touch layer 105 is located does not detect a human body, the side on which the first touch layer 104 is located is taken as a preferred side. For another example, on the basis of fig. 5, on the side where the second touch layer 105 is located, there is also a user B (not shown), and the information display apparatus detects a human body on both sides of the transparent display screen 101; at this time, the information display apparatus measures distances (d) of the user a and the user B from the transparent display screen 101, respectively_A0.3m) and (d)_B0.5 m); which one of the users a and B is at a distance from the transparent display 101 that is less than a preset distance threshold (d)₀0.4m), the side where the user is located is taken as the preferred side; due to d_A<d₀And d_B>d₀Therefore, the side where the user a is located is the preferred side. For another example, on the basis of fig. 5, there is also a user B (not shown) on the side where the second touch layer 105 is located, and the information display device detects a human body on both sides of the transparent display screen 101; at this time, the information display apparatus measures distances (d) of the user a and the user B from the transparent display screen 101, respectively_A' -0.3 m) and (d)_B' -0.5 m); whichever of the user a and the user B is closer to the transparent display 101 is the preferred side; due to d_A’<d_BTherefore, the side where the user a is located is set as the preferred side.

Preferably, the display screen comprises a transparent display screen and a light adjusting film arranged on one surface of the transparent display screen. The light adjusting film is an electronic light control material, and is generally made by injecting a liquid crystal/polymer mixed material between two transparent conductive films, under the condition that the two conductive films are not electrified, the light adjusting film is in an opaque state, and when an alternating voltage exists between the two conductive films, liquid crystal molecules are orderly arranged, and the light adjusting film is in a transparent state. When the light adjusting film is in an opaque state, the light adjusting film can also be used as a curtain of the projection display device.

Referring to fig. 8, in step S11, the information display apparatus detects the side of the user with respect to the display screen in the apparatus; thereafter in step S12, the information display device displays information through the display screen in a manner directed toward the location side, and keeps the dimming film energized if the dimming film is located on the location side of the transparent display screen, otherwise keeps the dimming film de-energized.

Specifically, in step S12, the information display device displays information through the display screen in a manner of facing the location side, and if the dimming film is located on the location side of the transparent display screen, the dimming film is kept powered on, otherwise, the dimming film is kept powered off, that is, a layer of dimming film is further attached to one of two surfaces of the transparent display screen; when the light adjusting film and the user are positioned on the same side of the transparent display screen, the light adjusting film is kept in the power-on state, and when the light adjusting film and the user are positioned on different sides of the transparent display screen, the light adjusting film is kept in the power-off state. Wherein the light adjusting film is transparent when the power is on and turns to be opaque when the power is off. Thus, the dimming film is configured to be transparent when located on the same side of the transparent display screen as the user and opaque when located on a different side of the transparent display screen from the user.

When a user and the light modulation film are positioned on different sides of the transparent display screen, and the user watches information displayed by the transparent display screen, the light modulation film in the opaque state can shield objects on the other side of the transparent display screen, so that the interference of the objects on the user is avoided, and the information acquisition efficiency and the user experience of the user are improved; and when the user and the light adjusting film are positioned on the same side of the transparent display screen, the light adjusting film in the transparent state can not influence the user to acquire the information displayed by the transparent display screen.

For example, referring to fig. 9, a user a is located at the left side of the transparent display screen 101, a first dimming film 102 and a first touch layer 104 are further attached to the left surface of the transparent display screen 101, and the first dimming film 102 is located between the first touch layer 104 and the transparent display screen 101; when the information display apparatus detects the presence of the user a to perform information display in a manner directed toward the user a and keeps the first light adjusting film 102 energized so that the first light adjusting film 102 is in a transparent state, the user a can view information displayed on the transparent display screen 101 through the first light adjusting film 102 and the first touch layer 104. For another example, referring to fig. 10, the user a is still located at the left side of the transparent display 101, the first touch layer 104 is attached to the left surface of the transparent display 101, and the second light modulation film 103 is attached to the right surface; when the information display device detects the presence of the user a to display information in a manner directed toward the user a and keeps the second dimming film 103 powered off so that the second dimming film 103 is in an opaque state, the user a can view information displayed on the transparent display 101 through the first touch layer 104 while an object on the right side of the transparent display 101 is shielded by the second dimming film 103. In this section, "left" and "right" are relative concepts used in fig. 9, and are used only for describing the present application in detail, and are not used for limiting the actual positional relationship of the relevant components in any way. In addition, the positions of the first touch layer 104 and the first dimming film 102 can be switched, for example, the first touch layer 104 is arranged between the first dimming film 102 and the transparent display screen 101.

Preferably, the display screen comprises a transparent display screen and further comprises light adjusting films respectively arranged on two sides of the transparent display screen. In step S11, the information display apparatus detects the side of the user with respect to the display screen in the apparatus; thereafter in step S12, the information display device displays information through the display screen in a manner directed to the local side, and the information display device is configured to:

1) keeping the light adjusting film on the side powered on, so that the light adjusting film is in a transparent state when being positioned on the same side of the transparent display screen with a user; or,

2) the dimming film on the side opposite to the side is kept powered off so that the dimming film is in an opaque state when it is on a different side from the transparent display screen than the user.

At the moment, when a user watches the information displayed by the transparent display screen, the dimming film on the different side of the transparent display screen from the user is in an opaque state, so that objects on the other side of the transparent display screen can be shielded, the interference of the objects on the user is avoided, and the information acquisition efficiency and the user experience of the user are improved; the dimming film which is at the same side of the transparent display screen with the user is in a transparent state, and the user can not be influenced to obtain the information displayed by the transparent display screen.

For example, referring to fig. 11, user a is located on the left side of the transparent display 101 and user B is located on the right side of the transparent display 101. A first touch layer 104 and a first light adjusting film 102 are attached to the left surface of the transparent display panel 101, and a second touch layer 105 and a second light adjusting film 103 are attached to the right surface. The information display device detects user a and user B, but user a is closer to the transparent display screen 101, so the transparent display screen is configured to display information in a manner toward user a, and the information display device keeps the first dimming film 102 powered on and the second dimming film 103 powered off so that the first dimming film is in a transparent state and the second dimming film is in an opaque state. At this time, the user a can see the information displayed on the transparent display 101 through the first touch layer 104 and the first light adjusting film 102, and the object on the right side of the transparent display 101 is shielded by the second light adjusting film 103. In this section, "left" and "right" are relative concepts used in fig. 9, and are used only for describing the present application in detail, and are not used for limiting the actual positional relationship of the relevant components in any way. In addition, the positions of the first touch layer 104 and the first dimming film 102 can be exchanged, and the positions of the second touch layer 105 and the second dimming film 103 can be exchanged, for example, the first touch layer 104 is arranged between the first dimming film 102 and the transparent display screen 101, or the second touch layer 105 is arranged between the second dimming film 103 and the transparent display screen 101.

Preferably, in step S11, the information display device detects the side of the user with respect to the display screen in the device through the sensing unit of the device. For example, whether user activity exists on two sides of the display screen is detected through an ultrasonic sensor, a pyroelectric infrared sensor, a human body proximity sensor, an infrared sensor, a sound sensor, an image sensor and the like distributed on the two sides of the display screen, and when the user activity is detected on one side, the side is used as the side where the current user is located relative to the display screen.

Preferably, the sensing unit comprises at least any one of: 1) an ultrasonic sensor; 2) a human proximity sensor; 3) a pyroelectric infrared sensor; 4) an infrared sensor; 5) a sound sensor; 6) an image sensor. In some embodiments, the user is detected relative to the display screen of the information display device by any one or a combination of the following:

1) by means of an ultrasonic sensor: the ultrasonic sensor is a sensor developed by utilizing the characteristics of ultrasonic waves (the ultrasonic waves are sound waves with the vibration frequency higher than 20kHz, can be generated by the vibration of a transduction wafer under the excitation of voltage, and have the characteristics of high frequency, short wavelength and good directivity), and mainly comprises a transmitting sensor (or called wave transmitter), a receiving sensor (or called wave receiver) and a control part; because the ultrasonic waves are reflected when touching the obstacles and generate Doppler effect when touching the moving objects, the obstacles (such as human bodies) can be detected by detecting the reflected echoes generated by the sent ultrasonic waves, so that whether the user exists on a certain side of the display screen or not is detected;

2) by human proximity sensor: the human body proximity sensor is an inductor which is based on the microwave Doppler principle, takes a planar antenna as an induction system and takes a microprocessor as control, and can be used for detecting the proximity action of a human body to a certain direction, thereby detecting the proximity action of a user to a display screen and further determining the side of the user relative to the display screen;

3) by pyroelectric infrared sensors: the pyroelectric infrared sensor can detect infrared rays radiated by a human body in a non-contact mode, convert the infrared rays into voltage signals and identify moving living beings and other non-living beings, so that the pyroelectric infrared sensor can be used for detecting whether a user exists on one side of the display screen;

4) by means of an infrared sensor: the infrared sensor can be divided into a thermal detector and a photon detector and can be used for detecting thermal radiation, and when the thermal radiation is detected to exist on one side of the display screen, the user on the side of the display screen is determined to exist;

5) by means of a sound sensor: the sound sensor can be used for receiving sound waves and converting sound signals into electric signals, and when the sound sensor on one side of the display screen detects the sound signals, the existence of a user on the side of the display screen can be determined;

6) by an image sensor: the image sensor may be classified into two types, namely, a CCD (Charge coupled device) and a CMOS (Complementary Metal-Oxide Semiconductor), according to different elements, and is a device for converting an optical image into an electronic signal, and when it is detected that an image acquired by the image sensor changes, or the image acquired by the image sensor includes a human body (for example, by performing face recognition on the image, or performing Pedestrian Detection (Pedestrian Detection) based on a HoG feature and a support vector machine, etc.), it may be determined that a user exists on a corresponding side of a display screen.

In some embodiments, the display screen comprises a curtain, and the information display apparatus further comprises projection means for projecting the curtain from both sides, respectively. Referring to fig. 12, in step S11, the information display device detects the side of the user relative to the display screen in the device; in step S12, the information display apparatus controls the projection device to display information on the curtain in a front projection manner from the side on which the information is displayed, or controls the projection device to display information on the curtain in a rear projection manner from the side opposite to the side on which the information is displayed.

For example, referring to fig. 13, the information display device includes a display screen, a first projection device 106 and a second projection device 107, the display screen includes a curtain 101 ', and the first projection device 106 and the second projection device 107 are respectively used for projecting to the curtain 101 ' from two sides of the curtain 101 '. When the information display device is configured to display information in a front projection manner, the information is projected to the curtain 101 'by a projection device which is positioned on the same side of the curtain 101' as the user to display the information; when the information display device is configured to display information in a rear projection manner, information is projected onto the curtain 101 'by a projection device located on a different side of the curtain 101' from the user to display the information. For example, when the information display device is configured to display information in a front projection manner and detects that the user C is located at the left side of the curtain 101 ', the first projection device 106 also located at the left side of the curtain 101 ' is controlled to project the information to the curtain 101 ' to display the information for the user C to watch; at this time, the curtain 101' may be a translucent curtain, or an opaque curtain. For another example, when the information display device is configured to display information in a rear projection manner and detects that the user C is located at the left side of the curtain 101 ', the second projection device 107 located at the right side of the curtain 101 ' is controlled to project the information to the curtain 101 ' so as to display the information for the user C to watch; at this time, the curtain 101' is a translucent curtain. In the case where the curtain 101 'is a translucent curtain, the light-adjusting film in the opaque state still has a certain light transmittance (although low), so the curtain 101' can be made of the light-adjusting film without being energized. In this section, "left" and "right" are relative concepts used in fig. 9, and are used only for describing the present application in detail, and are not used for limiting the actual positional relationship of the relevant components in any way. When the curtain 101 ' is made of a light-adjusting film, the curtain 101 ' is powered off when projection is needed, and when projection is not needed, the curtain 101 ' can be powered on, for example, when the curtain 101 ' is used in a meeting room, the curtain 101 ' is powered off when the projection device is in use, the curtain 101 ' becomes an opaque state, the projection device can normally project on the curtain 101 ', and when the meeting is ended and the projection device is used, the curtain 101 ' is powered on, the curtain 101 ' becomes a transparent state, and the transparent state can be used for indicating an idle state of the meeting room.

Preferably, the display screen further comprises two touch input devices respectively attached to two sides of the curtain. For example, referring to fig. 14, a first touch film 104 ' and a second touch film 105 ' are further attached to two sides of the curtain 101 ' for the user C and the user D to perform touch operations. The first touch film 104' and the second touch film are capacitive touch films and resistive touch films, and can be replaced by infrared emitting and receiving sensing elements, ultrasonic emitters and receivers, etc., which have the same principle as touch input devices attached to both sides of the transparent display screen, and are not described herein again and are included herein by way of reference. Of course, those skilled in the art will appreciate that the above-described touch input device is merely exemplary, and that other existing or future touch input devices may be suitable for use in the present application, and are also included within the scope of the present application and are incorporated herein by reference, for example, touch input devices including NFI (Near Field Imaging) touch devices. Particularly, when the information display device displays information in a rear projection manner, and when the user C or the user D performs a touch operation, the light projected to the curtain 101' by the projection device is not blocked by the user who is operating, compared with the front projection manner, so that the user operation efficiency and the user experience can be improved.

Preferably, referring to fig. 15, in step S11, when the information display device detects a touch operation of a user on the touch input device, the side of the user relative to the display screen is determined; in step S12, the information display apparatus controls the projection device to display information on the curtain in a rear-projection manner from the side opposite to the side on which the information is displayed.

For example, still referring to fig. 14, when a touch operation of the user C on the first touch film 104 'is detected, the second projection device 107 projects information to the curtain 101' to display the information in a rear projection manner for the user C to view; accordingly, when the touch operation of the user D on the second touch film 105 'is detected, the first projection device 106 projects the information to the curtain 101' to display the information in a rear projection manner for the user D to view.

In some embodiments, an information display device detects a user's presence side relative to a display screen in the device, the display screen being embedded in a window of a vehicle, and displays information through the display screen in a manner directed toward the presence side, the device being in communication with an on-board system of the vehicle. For example, a transparent display screen is embedded in the windshield or side window of a vehicle; when the user is detected to be on the outer side of the vehicle, vehicle state information and unlocking information are displayed in a mode of facing the outer side of the vehicle through the transparent display screen; when the user is detected to be on the inner side of the vehicle, the vehicle state information and the control information are displayed in a mode of facing the inner side of the vehicle through the transparent display screen. At the moment, the vehicle window can be used for displaying various information besides being used for observing the conditions inside and outside the vehicle, so that the operation process of a user is simplified, and the operation efficiency and the use experience of the user are improved.

Preferably, referring to fig. 16, the side includes an outer side of the vehicle; in step S12, the information display device controls the display screen to display notification information or door access information toward the outside of the vehicle. For example, referring to fig. 17, when the information display device detects that the user E is located outside the vehicle, information is displayed through the transparent display 101 ″ embedded in the window of the vehicle in a manner of facing the outside of the vehicle (i.e., facing the user E), such as notification information of the current vehicle's vehicle condition, owner identity information, owner contact information, or related entrance guard information for unlocking the vehicle. In particular, when a touch input device for a user to perform touch input is further attached to the outer side of the transparent display 101 ″, the vehicle can be unlocked in combination with the entrance guard information, for example, by matching a touch gesture of the user with a preset gesture, or by determining whether a password input by the user is correct.

Preferably, referring to fig. 18, the side includes an inner side of the vehicle; in step S12, the information display apparatus controls the display screen to display vehicle state information or vehicle control information toward the inside of the vehicle. For example, referring to fig. 19, when the information display device detects that the user F is located inside the vehicle, information is displayed through the transparent display 101 ″ embedded in the window of the vehicle in a manner of facing the inside of the vehicle (i.e., facing the user F), such as displaying the position and the travel track of the current vehicle, travel information, traffic conditions, etc., or a music or video playback interface, or vehicle control information such as vehicle stop, travel change, etc. In particular, when a touch input device for a user to perform touch input is further attached to the inside of the transparent display 101 ″, the vehicle can be controlled in conjunction with vehicle control information, such as changing a trip or parking, or control buttons as shown in fig. 3 are displayed.

Referring to fig. 20, according to another aspect of the present application, there is provided an information display apparatus including a detection module 11 and a display control module 12. The detection module 11 detects the side of the user relative to the display screen in the information display device; the display control module 12 displays information through the display screen in a manner toward the side.

Specifically, the detection module 11 detects the side of the user relative to the display screen in the information display device. For example, the information display device includes a display screen having front and back sides and capable of presenting contents such as graphics, text, and the like on the front and back sides. Wherein it may first be detected on which side the user is located in relation to the display screen in order to present the content to the user in the correct way. For example, in some embodiments, which side of the display screen the user is active on is detected by various known sensors (e.g., including, but not limited to, ultrasonic sensors, pyroelectric infrared sensors, human proximity sensors, sound sensors, image sensors, etc.); or when a touch input device (for example, including but not limited to a touch film based on the projected capacitance principle) attached to the side of the display screen detects a touch operation, determining that the user is located at the corresponding side of the display screen; or when an external input device (e.g., including but not limited to a keyboard, a touchpad, a motion sensing device, etc.) located on one side of the display screen detects an input, it is determined that the user is located on the corresponding side of the display screen.

The display control module 12 displays information through the display screen in a manner toward the side. For example, still taking the scenario shown in fig. 1 as an example, when the information display device detects that the user is located on the left side of the transparent display 101 through the camera (or the image sensor), the graphics, text, and the like that need to be presented to the user are displayed in a manner of facing to the left side, the information displayed on the transparent display 101 is facing to the user, and the graphics, text, and the like viewed by the user are displayed in a forward direction. Accordingly, if the information display apparatus detects that the user is located on the right side of the transparent display 101, information that needs to be displayed is displayed to the right side. Referring to the touch input panel shown in fig. 3, the main component of the touch input panel is an OLED touch display panel, which can perform double-sided display and double-sided touch. With reference to fig. 3, if the left side is the front side and the right side is the back side, when the user performs an operation on the left side, for example, the user points to click on the touch input panel, the content displayed on the touch input panel is as shown in fig. 3, a control button is displayed on the touch input panel, and the control button is marked with a "start" character; other information such as weather information is displayed below the control button. When the user performs touch input on the reverse side, the touch input panel horizontally inverts the display content, so that the content seen by the user on the reverse side is also the display content shown in fig. 3.

Preferably, when the detection module 11 detects a touch operation of a user on a display screen of the device, the side of the user opposite to the display screen is determined by detecting whether human bodies exist on two sides of the display screen. For example, still referring to fig. 5, when it is detected that the user a performs a touch operation on the first touch layer 104 or the second touch layer 105 attached to the surface of the transparent display screen 101, the position of the user a is detected by sensors (for example, including but not limited to an ultrasonic sensor, a pyroelectric infrared sensor, a human body proximity sensor, a sound sensor, and an image sensor) distributed at two sides of the transparent display screen 101; at this time, with respect to the transparent display 101, the sensor located at the side where the first touch layer 104 is located detects a human body (i.e., the user a), and the sensor located at the side where the second touch layer 105 is located does not detect a human body. Therefore, the information display apparatus determines that the user a is located on the side of the first touch layer 104 with respect to the transparent display screen 101, and displays information to be displayed through the transparent display screen 101 in a manner facing the side of the first touch layer 104, that is, in a manner facing the user a.

For example, still referring to fig. 5, with respect to the transparent display 101, when the information display apparatus detects a human body only on the side where the first touch layer 104 is located, and does not detect a human body on the side where the second touch layer 105 is located, the side where the first touch layer 104 is located is regarded as a preferred side. For another example, on the basis of fig. 5, on the side where the second touch layer 105 is located, there is also a user B (not shown), and the information display apparatus detects a human body on both sides of the transparent display screen 101; at this time, the information display apparatus measures distances (d) of the user a and the user B from the transparent display screen 101, respectively_A0.3m) and (d)_B0.5 m); which one of the users a and B is at a distance from the transparent display 101 that is less than a preset distance threshold (d)₀0.4m), the side where the user is located is taken as the preferred side; due to d_A<d₀And d_B>d₀Therefore, the side where the user a is located is the preferred side. For another example, on the basis of fig. 5, there is also a user B (not shown) on the side where the second touch layer 105 is located, and the information display device detects a human body on both sides of the transparent display screen 101; at this time, the information display apparatus measures distances (d) of the user a and the user B from the transparent display screen 101, respectively_A' -0.3 m) and (d)_B' -0.5 m); whichever of the user a and the user B is closer to the transparent display 101 is the preferred side; due to d_A’<d_BTherefore, the side where the user a is located is set as the preferred side.

The detection module 11 detects the side of the user relative to the display screen in the device; thereafter, the display control module 12 displays information through the display screen in a manner facing the location side, and keeps the dimming film powered on if the dimming film is located on the location side of the transparent display screen, otherwise keeps the dimming film powered off.

Specifically, the display control module 12 displays information through the display screen in a manner of facing the location side, and if the dimming film is located on the location side of the transparent display screen, the dimming film is kept powered on, otherwise, the dimming film is kept powered off, that is, a layer of dimming film is further attached to one of two surfaces of the transparent display screen; when the light adjusting film and the user are positioned on the same side of the transparent display screen, the light adjusting film is kept in the power-on state, and when the light adjusting film and the user are positioned on different sides of the transparent display screen, the light adjusting film is kept in the power-off state. Wherein the light adjusting film is transparent when the power is on and turns to be opaque when the power is off. Thus, the dimming film is configured to be transparent when located on the same side of the transparent display screen as the user and opaque when located on a different side of the transparent display screen from the user.

Preferably, the display screen comprises a transparent display screen and further comprises light adjusting films respectively arranged on two sides of the transparent display screen. The detection module 11 detects the side of the user relative to the display screen in the device; thereafter, the display control module 12 displays information through the display screen in a manner directed to the side, and the information display device is configured to:

Preferably, the detection module 11 detects the side of the user relative to the display screen of the information display device through a sensing unit of the information display device. For example, whether user activity exists on two sides of the display screen is detected through an ultrasonic sensor, a pyroelectric infrared sensor, a human body proximity sensor, an infrared sensor, a sound sensor, an image sensor and the like distributed on the two sides of the display screen, and when the user activity is detected on one side, the side is used as the side where the current user is located relative to the display screen.

In some embodiments, the display screen comprises a curtain, and the information display apparatus further comprises projection means for projecting the curtain from both sides, respectively. The detection module 11 detects the side of the user relative to the display screen in the device; the display control module 12 controls the projection device to display information on the curtain in a front projection manner from the side where the projection device is located, or controls the projection device to display information on the curtain in a rear projection manner from the side opposite to the side where the projection device is located.

Preferably, when the detection module 11 detects a touch operation of a user on the touch input device, determining the side of the user relative to the display screen; the display control module 12 controls the projection device to display information on the curtain in a rear-projection manner from the side opposite to the side on which the projection device is positioned.

Preferably, the side includes an outer side of the vehicle; the display control module 12 controls the display screen to display notification information or door opening access information in a manner of being directed to the outside of the vehicle. For example, referring to fig. 17, when the information display device detects that the user E is located outside the vehicle, information is displayed through the transparent display 101 ″ embedded in the window of the vehicle in a manner of facing the outside of the vehicle (i.e., facing the user E), such as notification information of the current vehicle's vehicle condition, owner identity information, owner contact information, or related entrance guard information for unlocking the vehicle. In particular, when a touch input device for a user to perform touch input is further attached to the outer side of the transparent display 101 ″, the vehicle can be unlocked in combination with the entrance guard information, for example, by matching a touch gesture of the user with a preset gesture, or by determining whether a password input by the user is correct.

Preferably, the side includes an inner side of the vehicle; the display control module 12 controls the display screen to display vehicle state information or vehicle control information toward the inside of the vehicle. For example, referring to fig. 19, when the information display device detects that the user F is located inside the vehicle, information is displayed through the transparent display 101 ″ embedded in the window of the vehicle in a manner of facing the inside of the vehicle (i.e., facing the user F), such as displaying the position and the travel track of the current vehicle, travel information, traffic conditions, etc., or a music or video playback interface, or vehicle control information such as vehicle stop, travel change, etc. In particular, when a touch input device for a user to perform touch input is further attached to the inside of the transparent display 101 ″, the vehicle can be controlled in conjunction with vehicle control information, such as changing a trip or parking, or control buttons as shown in fig. 3 are displayed.

The detection module 11 and the display control module 12 may be software modules, such as a program or a subroutine for implementing a certain function; or a hardware module, e.g., comprising a circuit or an integrated circuit; or a combined software/hardware module.
