Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example one
An embodiment of the present invention provides an interactive device capable of switching display contents, and referring to fig. 1, the interactive device may include:
the display screen 1 is used for providing a transparent display mode or a non-transparent display mode to display contents to be displayed. In this embodiment, when the display screen 1 is in the transparent display mode, a user interacts with an actual object through the display screen 1, so that the user can search and select a target object to obtain related information of the target object; when the display screen 1 is in the opaque display mode, the device can display corresponding content in a VR manner. It should be noted that the display screen 1 is normally in a transparent state, and a user can observe an object of interest through the display screen 1.
And the acquisition module 2 is used for acquiring the characteristic identifier corresponding to the selected target object when the display screen 1 is in the light-transmitting display mode. In this embodiment, the target object may be a commodity having a certain functional purpose, and the feature identifier of the target object may include: a partial or whole image of the target object (e.g., whole appearance, partial logo), a VR application link specific identification code (e.g., two-dimensional code) disposed on the target object, and so forth.
And the communication module 3 is connected with the internet (for example, wirelessly connected) and is used for acquiring the display content corresponding to the target object from the internet server. In this embodiment, the interactive device capable of switching the display content does not store the content to be displayed (the display content may include some two-dimensional or three-dimensional image information), but is connected to the internet through the communication module 3, and uploads the acquired feature identifier to the internet server, so as to quickly acquire the display content corresponding to the target object by using the computing capability of the internet server and the stored big data, thereby simplifying the structure of the interactive device capable of switching the display content on the one hand, and fully utilizing the storage and computing advantages of the internet big data on the other hand. In practical application, when the obtaining module 2 obtains the feature identifier, a corresponding identifier code may be generated, the communication module 3 uploads the identifier code to an internet server, and the identifier code may be packaged to send feature data carrying the current object to the server (which may be an overall appearance, mark information with strong identification sense on the object, or a relative position relationship between parts of the object itself).
And the control module 4 is respectively connected with the display screen 1, the acquisition module 2 and the communication module 3, and is used for controlling the display screen 1 to be switched to the opaque display mode and controlling the display screen 1 to play the display content acquired by the communication module 3 from the internet server when the acquisition module 2 acquires the feature identifier. In this embodiment, the control module 4 controls the display screen 1 to be in the transparent display mode when the user selects the target object. In practical application, after the control module 4 controls the display screen 1 to play the display content, the display screen 1 can be automatically controlled to be switched to a transparent display mode, so that a user can autonomously select other target objects to perform corresponding information interaction.
In this embodiment, when a user uses the interactive device capable of switching display contents to perform information interaction with an actual object, the user firstly sees through the display screen 1 in the transparent display mode to observe and select a target object (which may be a commodity with a certain functional purpose), and after selecting the target object, the user can firstly obtain a feature identifier of the target object through the obtaining module 2 (for example, a camera), for example: an image (whole or partial) of the target object, a VR application link-specific identification code set on the target object, or the like; then, the obtained feature identifier is transmitted to a server of the internet through the communication module 3, and the internet server performs calculation and retrieval on the stored big data to obtain display content related to the target object, for example: identifying a target object or a component of the target object by an image identification technology, and then searching corresponding display content (which can be two-dimensional display information or three-dimensional display information) of the target object by cloud computing; after searching the corresponding display content, the internet server transmits the display content to the interactive device capable of switching the display content, and the control module 4 controls the display screen 1 to be in the opaque display mode and plays the content to be displayed. In the operation and use process, the user has no operation behavior constraint, the process of man-machine interaction is free, and the user experience is good. In addition, the device breaks through the problem that the VR device cannot enable the user to freely interact with the actual object, the user can freely select the target object and acquire related information in a VR mode, and interaction experience is good.
In practical application, the display screen 1 can be implemented by two ways of fig. 2 and 3:
specifically, referring to fig. 2, the display screen 1 may include: an upper polarizing layer 10, an upper substrate 11, an upper transparent electrode 12, an upper alignment layer 13, a liquid crystal molecule layer 14, a lower alignment layer 15, a lower transparent electrode 16, a lower substrate 17, and a lower polarizing layer 18 are sequentially disposed. The display screen 1 further includes: a plurality of OLED cells 19 uniformly disposed between the lower substrate 17 and the lower transparent electrode 16, and a planarization layer 191 disposed between the OLED cells 19 and the lower transparent electrode 16. The polarization directions of the upper polarization layer 10 and the lower polarization layer 18 are perpendicular to each other.
Further, the control module 4 is electrically connected to the upper transparent electrode 12 and the lower transparent electrode 16, respectively, and drives the upper transparent electrode 12 and the lower transparent electrode 16 with level pulses to implement a first display voltage difference at this stage of the display screen 1, and enables the display screen 1 to be in a transparent display mode by combining with liquid crystal molecules in the liquid crystal layer under the driving of the voltage difference, so that a user can select a target object through the display screen 1.
Further, the control module 4 is further connected to the OLED unit 19, and is further configured to provide a second display voltage difference for the display screen 1 when the obtaining module 2 obtains the feature identifier, so that the display screen 1 is in the opaque display mode, and control the OLED unit 19 to play corresponding display content. In this embodiment, the control module 2 follows the time division multiplexing driving signal output mode when respectively driving the display screen 1 to switch between the transparent display mode and the opaque display mode, so as to avoid overlapping or confusion of the two modes.
In the present embodiment, the upper substrate 11 and the lower substrate 17 are the supporting structure of the display panel 1, and also provide a foundation for the attachment or deposition of other layers. When the display screen 1 is prepared, a plurality of OLED units 19 for displaying required display contents are uniformly deposited on the surface of one side of the lower substrate 17; after the OLED unit 19 is disposed on the lower substrate 17, a planarization layer 191 is deposited on the surface of the OLED unit 19 and the exposed surface of one side of the lower substrate 17 to planarize the surface unevenness caused by the OLED unit 19, thereby providing a good foundation for the deposition of subsequent structures; then, a lower transparent electrode 16, a lower alignment layer 15, a liquid crystal molecule layer 14, an upper alignment layer 13, and an upper transparent electrode 12 are sequentially deposited on the planarization layer 191, and finally, an upper polarization layer 10 and a lower polarization layer 18 are respectively attached to both sides of the upper substrate 11 and the lower substrate 17, which are in contact with the external air, to complete the preparation of the display panel 1.
In the following, with reference to fig. 1 and fig. 2, a brief description is given of how the display screen 1 switches the display mode:
in normal operation, natural light from the external environment passes through the display screen 1 in the direction from the upper substrate 11 to the lower substrate 17, and the user's eyes face the lower polarizing layer 18 to receive images displayed on the display screen 1.
Since the polarization directions of the upper polarization layer 10 and the lower polarization layer 18 are perpendicular, when natural light in the external environment enters through the upper polarization layer 10, polarized light with the same polarization direction is formed, and the polarization direction of the polarized light is perpendicular to the polarization direction of the lower polarization layer 18.
The liquid crystal molecules in the liquid crystal molecule layer 14 are macromolecular substances with a rod-shaped structure between a solid and a liquid, and the liquid crystal molecules are helical structures in a natural form, and have a rotary optical activity to light, that is, the polarization direction of polarized light passing through the liquid crystal molecule layer 14 can be changed so as not to be perpendicular to the polarization direction of the lower polarization layer 18, and then the polarized light can enter eyes of a user through the lower polarization layer 18. That is, when the control module 4 is the upper transparent electrode 12 and the first display voltage provided by the lower transparent electrode 16 is 0V, natural light in the external environment can enter the glasses of the user through the transparent display screen 1, or when the first display voltage provided by the control module 4 is 0V, the transparent display screen 1 is in the transparent display mode.
When the control module 4 provides a preset second display voltage difference (not 0) for the upper transparent electrode 12 and the lower transparent electrode 16, a magnetic field is generated between the upper transparent electrode 12 and the lower transparent electrode 16, the spiral structure of the liquid crystal molecules of the liquid crystal molecule layer 14 becomes a homodromous arrangement structure under the action of the electric field, and the direction of light rays is not rotated at all, so that the polarized light perpendicular to the polarization direction of the lower polarization layer 18 cannot pass through the lower polarization layer 18, and thus, a user cannot see the light rays in the external environment through the display screen 1. That is, when the control module 4 provides the preset second display voltage difference (not 0), the display screen 1 is in the opaque display mode. It should be noted that, for the liquid crystal molecules with different material characteristics, the present invention does not limit the voltage relationship applied to the upper transparent electrode 12 and the lower transparent electrode 16 by the control module 4, for example, for the liquid crystal material used in the lower panel process of the vertical alignment display system, when the voltage difference between the upper and lower transparent electrodes is zero, the liquid crystal molecules are normally upright and in the opaque mode, and conversely, when the voltage difference between the upper and lower transparent electrodes is non-zero and is another voltage difference extreme value, the liquid crystal molecules are driven to rotate and in the transparent mode.
It should be noted that the OLED unit 19 itself has weak absorption of natural light and good light transmittance, and can display images by self-luminescence, that is, no matter the display screen 1 is in the light-transmitting display mode or the light-proof display mode, a user can see a virtual image displayed by the OLED unit 19.
Alternatively, the structure of the display panel 1 may also be as shown in fig. 3, which differs from the structure shown in fig. 2 in that a planarization layer 191 may be disposed between the lower transparent electrode 16 and the lower alignment layer 15, all the other things being equal. The working principle of the display screen 1 shown in fig. 3 is the same as that of the display screen 1 shown in fig. 2, and the description is omitted here.
Further, both the upper transparent electrode 12 and the lower transparent electrode 16 may be made of an indium tin oxide semiconductor transparent conductive film. Thus, the light transmission of the display screen 1 is not influenced, and the normal work of the electrodes can be guaranteed.
Further, both the substrate 11 and the lower substrate 17 may be made of transparent glass. This does not affect the light transmission of the display screen 1, but the display screen 1 provides a good support effect.
In this embodiment, the content that can be displayed by the interactive device capable of switching the display content may include not only two-dimensional or three-dimensional image information, but also audio information played in cooperation with the image information.
Optionally, referring to fig. 1, the interactive device capable of switching content display modes may further include:
and the sound output module 5 is connected with the control module 4 and is used for outputting the audio information in the display content.
In this embodiment, the content to be displayed may not only be information such as images and videos, but also include audio information, and the audio part in the content to be displayed may be synchronously output through the sound output module 5, so that the information acquisition approaches of the user are enriched.
The embodiment of the invention forms an interactive device capable of switching display contents through a display screen, an acquisition module, a communication module and a control module, wherein the display screen can provide a transparent display mode or an opaque display mode to display contents to be displayed, a user freely selects a target object through the display screen when the display screen is in the transparent display mode, obtains a characteristic identifier of the target object through the acquisition module after selecting the target object, transmits the characteristic identifier to an Internet server through the communication module to obtain display contents corresponding to the target object, and finally switches the display screen to the opaque display mode through the control module to play the obtained display contents. Therefore, the problem that the VR device cannot enable the user to freely interact with the actual object is solved, the user can freely select the target object and acquire related information in a VR mode, and interaction experience is good.
