[0002] In the prior art, a traditional liquid crystal display (LCD) needs to rely on a light source provided by a backlight to provide screen brightness.

[0019] Figure 2 A transparent bidirectional display device provided by an embodiment of the present application is shown. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of illustration and description and are not used to limit the scope of protection of the present application.

In addition, those skilled in the art, under the guidance of the contents of this application, can add one or more other operations to the flowchart, or remove one or more operations from the flowchart.

[0021] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0022] In the prior art, a common liquid crystal display screen includes a backlight, and the brightness of the liquid crystal display screen is provided by the backlight. However, the backlight itself cannot present a transparent effect, so the liquid crystal display screen cannot be made into a transparent display screen. If the liquid crystal display screen is made into a light box type LCD or a holographic cabin by pulling apart the distance between the liquid crystal screen and the backlight module to present a pseudo-transparent effect at the display surface of the liquid crystal screen, the display content of the liquid crystal screen cannot be viewed at the back of the light box type LCD or the holographic cabin, and the liquid crystal display screen still cannot be made into a transparent display screen.

[0023] Therefore, embodiments of the present application provide a transparent display device and a transparent bidirectional display device. A liquid crystal screen with a transparent display effect after power-on is selected, a transparent light guide plate is arranged on a side where a display back surface of the liquid crystal screen is located, a light source is arranged on a preset surface of the transparent light guide plate, and the preset surface is perpendicular to the liquid crystal screen. Light emitted by the light source can be refracted to the liquid crystal screen through the transparent light guide plate to provide the brightness required by the liquid crystal screen display. A touch layer is arranged on a side where a display surface of the liquid crystal screen is located to enable the transparent display device to have a touch function. A first glass layer and a second glass layer are used as the outermost protective structure of the transparent display device to solve the technical problem that the liquid crystal display screen in the prior art cannot present a transparent effect, and achieve the technical effect of a light and thin transparent display device. Details are as follows. Please refer to Figure 1 , Figure 1 FIG. 1 is a structural schematic diagram of a transparent display device provided by an embodiment of the present application. As shown in FIG. 1, the transparent display device provided by the embodiment of the present application includes a liquid crystal screen 101, a transparent light guide plate 102, a light source 103, a touch layer 104, a first glass layer 1051, and a second glass layer 1052. Figure 1 The liquid crystal screen is a liquid crystal screen with a transparent display effect after power-on, and includes a display surface 1011 and a display back surface 1012. The transparent light guide plate is arranged on a side where the display back surface of the liquid crystal screen is located. The light source is arranged on a preset surface of the transparent light guide plate, and the preset surface is perpendicular to the display surface. The light emitted by the light source is directed to the transparent light guide plate, and the transparent light guide plate is used to convert the light provided by the light source into a surface light source that illuminates the display surface. The touch layer is arranged on a side where the display surface of the liquid crystal screen is located. The first glass layer is arranged on a side of the touch layer away from the liquid crystal screen, and the second glass layer is arranged on a side of the transparent light guide plate away from the liquid crystal screen.

[0024] The display face refers to the face facing the audience and used to present the display content, i.e. the display content of the liquid crystal screen is presented through the display face. The display content presented by the display face is a normal forward picture, when the display content includes text and pictures, the text and images are displayed in a forward direction, and the text is readable. The display back refers to the face opposite to the audience, the display back cannot provide normal display content, but presents a mirror image picture of the display content through the transparent liquid crystal screen, i.e. the text and pictures provided by the display back are pictures obtained by horizontally flipping the display content of the display face, the text and images are displayed in a mirror image, and the text is unreadable.

[0025] Although the liquid crystal screen presents a transparent display effect after being powered on, only the display face of the single liquid crystal screen can provide a normal forward picture. Since the liquid crystal screen is transparent, the display back of the liquid crystal screen can also see the display content of the display face, but the display back can only present a mirror image picture of the display face.

[0026] For example, the liquid crystal screen can be an IPS (In-Plane Switching) liquid crystal screen or a VA (Vertical Alignment) liquid crystal screen, and the VA liquid crystal screen can be a normally black VA liquid crystal screen.

[0027] Further, the liquid crystal screen itself has a light transmittance, but without a light source, the brightness is too low, so that the audience cannot see the display content presented by the display face. Further, the transparent light guide plate is arranged on the display back of the liquid crystal screen, and the light source is arranged on a preset face of the transparent light guide plate perpendicular to the display face, so that the transparent light guide plate can convert the light generated by the light source into a surface light source irradiating to the display face to increase the brightness of the liquid crystal screen.

[0028] That is, in the prior art, since the backlight module is placed on the back of the liquid crystal screen, the liquid crystal screen cannot present a transparent display effect. Further, the present application places the light source on the side of the transparent light guide plate, i.e. on the preset face of the transparent light guide plate perpendicular to the display face, so that the light provided by the light source first enters the inside of the transparent light guide plate through the preset face, and then is reflected and scattered by the light guide points in the inside of the transparent light guide plate into a direction perpendicular to the display face, so that the light of the light source is converted into a surface light source irradiating to the display face to provide brightness to the liquid crystal screen, and then the audience can view the display content from the display face of the liquid crystal screen.

[0029] For example, the size and arrangement of the light guide points in the inside of the transparent light guide plate can be designed to make the transparent light guide plate uniformly light the display face. The transparent light guide plate is prepared by screen printing process on optical grade PMMA or PC material to print light guide points.

[0030] Exemplarily, the light-emitting source includes one, and one light-emitting source can be arranged on any one preset surface of the transparent light guide plate. Alternatively, the light-emitting source includes a plurality of light-emitting sources, and the plurality of light-emitting sources are arranged on at least one preset surface of the transparent light guide plate.

[0031] That is, the plurality of light-emitting sources can be arranged on each preset surface of the transparent light guide plate, or can be arranged on only one preset surface, or can be arranged on two or more preset surfaces and arranged on at least one preset surface without being arranged on at least one preset surface, that is, the number of light-emitting sources arranged on each preset surface can be the same or different.

[0032] The arrangement position of the light-emitting source should not hinder the transparent display effect of the liquid crystal screen, and the arrangement position of the light-emitting source should be able to illuminate the transparent light guide plate and convert the light-emitting source into a surface light source of the liquid crystal screen by matching the light guide points of the transparent light guide plate.

[0033] The touch layer is arranged on the display surface of the liquid crystal screen to enable the transparent display device to have a touch function. The touch layer can be a transparent PET film (nanometer sensing touch film). The nanometer sensing touch film is transparent by itself and does not affect the transparent display effect of the transparent display device.

[0034] The first glass layer and the second glass layer are the outermost layers on both sides of the transparent display device. The first glass layer is arranged on the side of the touch layer away from the liquid crystal screen, and the second glass layer is arranged on the side of the transparent light guide plate away from the liquid crystal screen. The first glass layer and the second glass layer mainly serve to bear and protect the liquid crystal screen from external damage.

[0035] Exemplarily, the touch layer is fully attached to the display surface of the liquid crystal screen, and the first glass layer is fully attached to the side of the touch layer away from the display surface. That is, the touch layer and the display surface of the liquid crystal screen are fully attached, and the first glass layer and the touch layer are fully attached to increase the anti-explosion and anti-violence capability and improve the display effect.

[0036] Exemplarily, the second glass layer can be fully attached, or frame-attached, or zero-attached to the side of the transparent light guide plate away from the liquid crystal screen, and the present application does not limit this.

[0037] Specifically, the transparent display device further includes a mainboard, wherein the mainboard is connected to the light-emitting source, the liquid crystal screen and the touch layer respectively, and the mainboard is configured to control the display content of the liquid crystal screen and identify the coordinate position clicked on the touch layer.

[0038] Exemplarily, the mainboard is placed in a direction perpendicular to the display surface of the liquid crystal screen, for example, the mainboard can be placed on the bottom surface or the top surface of the transparent display device, and the liquid crystal screen, the transparent light guide plate, the touch layer, the first glass layer and the second glass layer are all placed on the mainboard. That is, the mainboard cannot be placed on the display surface and the display back surface of the liquid crystal screen, so as to avoid the mainboard interfering with the transparent display effect of the liquid crystal screen.

[0039] The mainboard should be provided with a power supply circuit, which can provide voltages required by the light emitting source, the liquid crystal screen and the touch layer respectively, so that the light emitting source can emit light outward, the liquid crystal screen can provide display content, and the touch layer can provide corresponding electrical signals when being clicked. In addition, the mainboard also includes a controller, which should be configured to provide control signals to the liquid crystal screen to change the display content of the liquid crystal screen, and the controller of the mainboard can detect the changed electrical signals (such as voltage signals) when the touch layer is clicked, and identify the coordinate position on the touch layer that is clicked through the changed electrical signals, so that the controller of the mainboard can change the display content of the liquid crystal screen through the coordinate position.

[0040] Specifically, the transparent display device further includes a voice module, and the mainboard is connected with the voice module, wherein the voice module is configured to receive voice information of a user and send the voice information to the mainboard, and the mainboard is configured to determine response information corresponding to the voice information and display content corresponding to the response information through the liquid crystal screen.

[0041] The voice module should at least include a microphone, which collects voice information spoken by the user and converts the voice information into an electrical signal and sends it to the processor of the mainboard, the processor of the mainboard converts the voice information into text information by analyzing the electrical signal, and the processor replies to the text information through a large language model and displays the response information of the reply through the display surface of the liquid crystal screen, so that the user and the transparent display device can interact through voice and text.

[0042] Based on the same application concept, the embodiments of the present application also provide a transparent bidirectional display device corresponding to the transparent display device provided in the above embodiments. Since the transparent bidirectional display device in the embodiments of the present application solves the problem in a similar way to the transparent display device in the above embodiments of the present application, the implementation of the transparent bidirectional display device can be referred to the implementation of the transparent display device, and the repeated parts will not be described here.

[0043] Please refer to Figure 2 , Figure 2 is a structural schematic diagram of a transparent bidirectional display device provided by the embodiments of the present application. As shown in Figure 2As shown, the transparent bidirectional display device provided by the embodiment of the present application comprises: a first liquid crystal screen 2011 and a second liquid crystal screen 2012, the liquid crystal screen is a liquid crystal screen with transparent display effect after power-on, the liquid crystal screen comprises a display surface and a display back surface, the display back surface of the first liquid crystal screen and the display back surface of the second liquid crystal screen are oppositely arranged; a transparent light guide plate 202, which is arranged between the display back surface of the first liquid crystal screen and the display back surface of the second liquid crystal screen; a light emitting source 203, which is arranged on a preset surface of the transparent light guide plate, the preset surface is perpendicular to the display surface, the light emitting source emits light rays to the transparent light guide plate, and the transparent light guide plate is used to convert the light rays provided by the light emitting source into a surface light source illuminating the display surface of the first liquid crystal screen and a surface light source illuminating the display surface of the second liquid crystal screen; a first touch layer 2041 and a second touch layer 2042, the first touch layer is arranged on the side where the display surface of the first liquid crystal screen is located, and the second touch layer is arranged on the side where the display surface of the second liquid crystal screen is located; a first glass layer and a second glass layer, the first glass layer is arranged on the side of the first touch layer away from the first liquid crystal screen, and the second glass layer is arranged on the side of the second touch layer away from the second liquid crystal screen.

[0044] As shown in the figure, Figure 2 The first liquid crystal screen and the second liquid crystal screen are oppositely arranged on the two sides of the transparent light guide plate, the display surface 20111 of the first liquid crystal screen and the display surface 20121 of the second liquid crystal screen do not contact the transparent light guide plate, and the display back surface 20112 of the first liquid crystal screen and the display back surface 20122 of the second liquid crystal screen contact the transparent light guide plate. That is, the display surface of the first liquid crystal screen and the display surface of the second liquid crystal screen both face the outside of the transparent bidirectional display device.

[0045] In addition, the light emitting source is located on the preset surface of the transparent light guide plate, the light rays of the light emitting source illuminate the transparent light guide plate, and each light guide point of the transparent light guide plate converts the light rays of the light emitting source into a direction perpendicular to the display surface of the first liquid crystal screen and a direction perpendicular to the display surface of the first liquid crystal screen, so as to construct a surface light source for the first liquid crystal screen and a surface light source for the second liquid crystal screen through the light emitting source and the transparent light guide plate, to provide display brightness to the first liquid crystal screen and the second liquid crystal screen, and the more the number of light emitting sources, the greater the display brightness.

[0046] The light emitting source of the transparent bidirectional display device can include one, and one light emitting source is arranged on any one preset surface of the transparent light guide plate; or the light emitting source of the transparent bidirectional display device can also include multiple, and multiple light emitting sources are arranged on at least one preset surface of the transparent light guide plate, and the arrangement mode of the multiple light emitting sources is similar to that of the light emitting source of the transparent display device, which will not be described here.

[0047] Exemplarily, the first liquid crystal screen and the second liquid crystal screen can be selected from an IPS (In-Plane Switching) liquid crystal screen or a VA (Vertical Alignment) liquid crystal screen, and the VA liquid crystal screen can be selected from a normal black VA liquid crystal screen. The transparent light guide plate is prepared by screen printing process on optical grade PMMA or PC material to print out light guide points, and by setting the size and arrangement of the light guide points on the transparent light guide plate, the light of the light source is converted into a direction perpendicular to the display surface of the first liquid crystal screen and the display surface of the second liquid crystal screen.

[0048] The first touch screen is arranged on the display surface of the first liquid crystal screen, and the second touch screen is arranged on the display surface of the second liquid crystal screen, so that the double-sided liquid crystal screens of the transparent bidirectional display device have touch functions.

[0049] Exemplarily, the first touch layer is fully attached to the display surface of the first liquid crystal screen, the first glass layer is fully attached to the side of the first touch layer away from the first liquid crystal screen, and / or the second touch layer is fully attached to the display surface of the second liquid crystal screen, and the second glass layer is fully attached to the side of the second touch layer away from the second liquid crystal screen.

[0050] That is, the first touch screen is fully attached to the display surface of the first liquid crystal screen, the second touch screen is fully attached to the display surface of the second liquid crystal screen, the first glass layer is fully attached to the side of the first touch screen away from the first liquid crystal screen, and the second glass layer is fully attached to the side of the second touch screen away from the second liquid crystal screen, to achieve the effects of increasing the anti-explosion and anti-violence ability and improving the display effect.

[0051] Exemplarily, the transparent bidirectional display device further comprises a mainboard, wherein the mainboard is connected to the light source, the first liquid crystal screen, the second liquid crystal screen, the first touch layer and the second touch layer respectively, and the mainboard is configured to control the first liquid crystal screen and the second liquid crystal screen to display content and identify the coordinate position clicked on the first touch layer and the second touch layer.

[0052] That is, the mainboard should at least be provided with a power supply circuit to provide the required voltage to the light source, the first liquid crystal screen, the second liquid crystal screen, the first touch layer and the second touch layer respectively. Moreover, the setting position of the mainboard should avoid interfering with the transparent display effect of the liquid crystal screen, and should not be placed in the direction of the display surface of the first liquid crystal screen and the display surface of the second liquid crystal screen, but can be placed in the direction perpendicular to the display surface of the liquid crystal screen, for example, the mainboard can be placed on the bottom surface or the top surface of the transparent display device.

[0053] And the mainboard further comprises a controller, the controller of the mainboard provides corresponding control signals to the first liquid crystal screen and / or the second liquid crystal screen to change the display content of the display surface of the first liquid crystal screen and / or the display content of the display surface of the second liquid crystal screen. And when the first touch layer is clicked by the user, the controller of the mainboard can detect the changed electrical signal (such as voltage signal) when the first touch layer is clicked, and identify the first coordinate position clicked on the first touch layer through the changed electrical signal, so that the controller of the mainboard changes the display content of the first liquid crystal screen through the first coordinate position; and / or when the second touch layer is clicked by the user, the controller of the mainboard can detect the changed electrical signal (such as voltage signal) when the second touch layer is clicked, and identify the second coordinate position clicked on the second touch layer through the changed electrical signal, so that the controller of the mainboard changes the display content of the second liquid crystal screen through the second coordinate position.

[0054] For example, the display surface of the first liquid crystal screen and the display surface of the second liquid crystal screen can present the same display content or different display content, which is not limited in the present application.

[0055] For example, the transparent bidirectional display device further comprises a voice module connected with the mainboard, wherein the voice module is configured to receive voice information of the user and send the voice information to the mainboard, and the mainboard is configured to determine response information corresponding to the voice information and display display content corresponding to the response information through the first liquid crystal screen and / or the second liquid crystal screen.

Furthermore, the double sides of the transparent bidirectional display device can present display content to the audience, and the users on both sides of the transparent bidirectional display device can also see the expressions and gestures of the opposite party through the transparent bidirectional display device, improving the interactive experience.

[0057] Exemplarily, the display content provided by the display surface of the first liquid crystal screen and the display surface of the second liquid crystal screen can be the same, both displaying the text information converted from the voice information obtained by the processor of the mainboard by analyzing the electric signal and the response information of the large language model replying to the text information. The display content provided by the display surface of the first liquid crystal screen and the display surface of the second liquid crystal screen can also be different, the display surface of the first liquid crystal screen can display the text information converted from the voice information obtained by the processor of the mainboard by analyzing the electric signal, and the display surface of the second liquid crystal screen can display the response information of the large language model replying to the text information.

Thus, the user producing the lip movement is determined through face recognition, so as to correspond the user speaking at each moment with the recognized voice information.

[0059] Exemplarily, if the first user and the second user communicate, the first user uses the first language, the second user uses the second language, and the first voice information corresponding to the first user and the second voice information corresponding to the second user are determined through face recognition, the large language model can be used to translate the first voice information into the first translation information in the second language and the second voice information into the second translation information in the first language, so that the first translation information and the second translation information are correspondingly presented through the display device, so that each user can clearly understand the content said by the other user.
