Referring to
Herein, a size of the first opening 111 of the frame 110 may be different from that of the second opening 112.
For instance, a size of the first opening 111 of the frame 110 may be greater than that of the second opening 112.
The reason for this is that the transparent display panel 120 and the control module 130 for controlling the transparent display panel 120 are disposed in the first opening 111 and the second opening 112 of the frame 100, respectively.
In some cases, a size of the first opening 111 of the frame 110 may be equal to that of the second opening 112.
Herein, since the size of the first opening 111 of the frame 110 is a region for disposing the transparent display panel 120 therein, it may vary according to a size of the transparent display panel 120.
And, the size of the first opening 111 of the frame 110 may vary according to a door size of a product in which a transparent display device will be installed.
In some cases, according to a shape of a door of a product in which the transparent display device will be installed, locations of the first and second openings 111 and 112 of the frame 110 may be switched to each other.
For instance, with respect to the transparent display device, the first opening 111 of the frame 110 in which the transparent display panel 120 is disposed may be located at a top end of a door of a product to be installed, and the second opening 112 of the frame 110 in which the control module 130 is disposed may be located at a bottom end of the door of the product to be installed.
Alternatively, with respect to the transparent display device, the first opening 111 of the frame 110 in which the transparent display panel 120 is disposed may be located at a bottom end of a door of a product to be installed, and the second opening 112 of the frame 110 in which the control module 130 is disposed may be located at a top end of the door of the product to be installed.
Alternatively, with respect to the transparent display device, the first opening 111 of the frame 110 in which the transparent display panel 120 is disposed may be located at a right side of a door of a product to be installed, and the second opening 112 of the frame 110 in which the control module 130 is disposed may be located at a left side of the door of the product to be installed.
Alternatively, with respect to the transparent display device, the first opening 111 of the frame 110 in which the transparent display panel 120 is disposed may be located at a left side of a door of a product to be installed, and the second opening 112 of the frame 110 in which the control module 130 is disposed may be located at a right side of the door of the product to be installed.
Subsequently, a transparent cover 140 may be disposed in front of the first opening 111 of the frame 110 and a non-transparent or transparent cover may be disposed in front of the second opening 112 of the frame 110.
Herein, the transparent cover 140 may include tempered glass capable of protecting the transparent display panel 120.
And, a rear surface of the transparent cover 140 may come into contact with a front surface of the transparent display panel 120.
In some cases, the rear surface of the transparent cover 140 may be disposed in a manner of being spaced apart from the front surface of the transparent display panel 120.
Herein, the transparent display panel 120 may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, and a 3D display, and have a configuration of a transparent or light-transmissive type in order for a user to view a scene in rear of the transparent display panel 120.
For one representative example of the transparent display panel 120, there is TOLED (transparent OLED) or the like and a rear structure of the transparent display panel 120 may have a light-transmissive structure as well. Owing to such a structure, a user can view an object or thing located in rear of the transparent display device through a region occupied by the transparent display panel 120.
According to an implementation type, the transparent display device may include two or more transparent display panels 120. For instance, a plurality of the transparent display panels 120 may be disposed in a manner of being spaced apart from each other or formed integrally in a single plane, or may be disposed in different planes, respectively.
In case that the transparent display panel 120 and a touch sensor mutually configure a layered structure or are formed integrally, the transparent display panel 120 may be used as an input device as well as an output device.
Herein, if the touch sensor has a configuration of one of a touch film, a touch sheet, a touch pad and the like for example, the touch sensor can configure the layered structure by being stacked on the transparent display panel 120 or may be integrally formed by being included in the configuration of the transparent display panel 120.
A transparent adhesive may be disposed between the rear surface of the transparent cover 140 and the transparent display panel 120. For instance, the transparent adhesive may be disposed on a front edge of the transparent display panel 120.
In some cases, alternatively, the transparent adhesive may be disposed on the whole front surface of the transparent display panel 120.
In doing so, a thickness of the transparent adhesive may be smaller than that of the transparent display panel 120.
And, an anti-reflective (AR) coating layer may be formed on the front surface of the transparent cover 140.
The reason for this is that if the transparent cover 140 reflects an external light, luminance and contrast for an image displayed on the transparent display panel 120 may be lowered.
Moreover, an airgap 180 may be formed between the rear surface of the transparent display panel 120 and a front surface of a door unit of a prescribed product.
The reason for this is described as follows. First of all, since humidity increases due to a temperature difference between the transparent display panel 120 and the door unit of the product, it may degrade the transparent display panel 120. If so, the durability of the transparent display panel 120 may be degraded.
For instance, if a product in which a transparent display device will be installed is a cooler, a door of the cooler may have a dual door structure.
Namely, the door of the cooler may have a structure in which a front door 230 and a rear door 220 are disposed in a manner of being evenly spaced apart from each other and can be attached to a support 240, which is disposed in-between, through an adhesive.
And, a cooler door frame 250 may be disposed on a door edge of the cooler.
Herein, a first gap between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product may be smaller than a second gap between the front door 230 and the rear door 220 of the cooler door.
In some cases, the first gap and the second gap may be equal to each other.
In some other cases, the first gap may be greater than the second gap.
Thus, the first gap between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product may be variable according to a humidity level within the airgap.
For instance, a gap adjusting unit (not shown) configured to adjust the first gap between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product may be disposed in the frame 110.
The gap adjusting unit may include an adjusting plate extending from a rim of the frame 110 in a direction of the first opening 111 and a hinge configured to connect the adjusting plate and the frame 110 and rotate the adjusting plate in a direction of the door unit of the prescribed product.
Herein, in response to a control signal of the control module 130, the gap adjusting unit can adjust the first gap between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product.
For instance, a humidity sensor configured to sense humidity within the airgap 180 may be disposed in the frame 110. And, the control module 130 can control the gap adjusting unit by receiving a sensing signal of the humidity sensor.
Namely, if the humidity within the airgap 180 is high, the controller module 130 controls the gap adjusting unit to increase the first gap. If the humidity within the airgap 180 is low, the controller module 130 controls the gap adjusting unit to decrease the first gap.
Therefore, the present invention prevents the transparent display panel 120 from being adversely affected by humidity, thereby enhancing durability.
In some cases, a ventilating unit (not shown) configured to discharge heat generated from the control module 130 into the space between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product may be disposed in the second opening 112 of the frame 110.
Herein, the ventilating unit enables air with heat to flow into the space between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product, thereby removing humidity within the airgap 180.
For instance, a humidity sensor configured to sense humidity within the airgap 180 may be disposed in the frame 110. The control module 130 can control the ventilating unit by receiving a sensing signal of the humidity sensor.
Therefore, the present invention prevents the transparent display panel 120 from being adversely affected by humidity, thereby enhancing durability.
Meanwhile, the frame 100 may include an inner frame 116 coming into contact with the rim of the door unit of the prescribed product and an outer frame 115 disposed by being spaced apart from the inner frame 116.
Herein, the inner frame 116 is attached to the rim of the transparent cover 140 configured to cover the first opening 111 and the outer frame 115 may be spaced apart from the transparent cover 140.
In this case, an IR (infrared) touch sensor 150 is disposed between the outer frame 115 and the transparent cover 140, thereby sensing a user's touch.
In some cases, an adhesive layer or supporter may be disposed between the outer frame 115 and the transparent cover 140.
And, a wiring 160 configured to electrically connect the control module 130 and the transparent display panel 120 may be disposed between the inner frame 116 and the outer frame 115.
Namely, by disposing the wiring 160 in a space between the inner frame and the outer frame 115, the space can be used efficiently.
The frame 110 including the inner frame 116 and the outer frame 115 may further include an extending frame 117 extending from end portions of the inner and outer frames 116 and 115 in a direction of the door unit of the prescribed product.
Herein, the extending frame 117 comes into contact with a lateral surface of the cooler door frame 250 of the door unit and can be then jointed by a joint part such as a joint screw or the like.
In order to display information related to goods stored in the door unit of the prescribed product, the control module 130 can control the transparent display panel 120.
In some cases, the control module 130 may control the transparent display panel 120 to simultaneously display a transmissive region for transmitting light and a non-transmissive region for not transmitting light.
In doing so, the control module 130 may control the transparent display panel 120 to display the information on the goods stored in the door unit of the prescribed product on the non-transmissive region.
In some cases, the control module 130 may control the transparent display panel 120 to display information related to goods viewable through the transmissive region among the goods stored in the door unit of the prescribed product.
Referring to
Herein, the frame 110 may be installed to cover a front surface of the door unit 210 of the prescribed product 200, or can be separated from the front surface of the door unit 210 of the prescribed product 200.
Herein, an extending frame (denoted by 117 in
For instance, the transparent display device 100 may be jointed with the door unit of the product 200 (e.g., cooler, etc.) by various joint mechanisms.
Herein, the joint mechanisms may include a mechanism of fixing using a joint bold, a mechanism of jointing by forming a joint recess and a joint projection.
Therefore, according to the present invention, the frame 110 in which the transparent display panel 120 and the control module are installed is attached to or detached from the front surface of the door unit 210 of the prescribed product 200. Therefore, the transparent display device 100 can be simply installed or uninstalled, parts can be easily replaced, and mass production is available.
Referring to
And, an airgap 180 may be formed between a rear surface of the transparent display panel 120 and a front surface of a door unit 210 of a prescribed product.
A frame 110 may include an inner frame 116 coming into contact with a rim of the door unit 210 of the prescribed product and an outer frame 115 disposed by being spaced apart from the inner frame 116.
Herein, the inner frame 116 is attached to the rim of the transparent cover 140 and the outer frame 115 may be spaced apart from the transparent cover 140.
In this case, an IR (infrared) touch sensor 150 is disposed between the outer frame 115 and the transparent cover 140, thereby sensing a user's touch.
And, a wiring configured to electrically connect a control module 130 and the transparent display panel 120 may be disposed between the inner frame 116 and the outer frame 115.
The frame 110 including the inner frame 116 and the outer frame 115 may further include an extending frame 117 extending from end portions of the inner and outer frames 116 and 115 in a direction of the door unit of the prescribed product.
Herein, the extending frame 117 may be jointed and fixed to a lateral surface of a cooler door frame 250 of the door unit by a joint screw 260.
Namely, the extending frame 117 extending from the rim of the frame 110 in the direction of the door unit 210 of the prescribed product 200 can be jointed with the lateral surface of the rim of the door unit 210 of the prescribed product 200.
In some cases, the frame 110 of the transparent display device may be jointed by a mechanism of forming a multitude of joint recesses and a multitude of joint projections at the frame 110 and the cooler door frame 250 and then combining them with each other as well as by the joint mechanism using the joint screw 260.
Referring to
The reason for this is that as the transparent display panel 120 may be adversely affected by humidity generated due to a temperature difference between the transparent display panel 120 and the door unit 210 of the product, durability of the transparent display panel 120 can be degraded.
Herein, the gap between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product may be variable according to a humidity level within the airgap.
For instance, a gap adjusting unit 270 configured to adjust the gap between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product may be disposed in the frame 110.
The gap adjusting unit 270 may include an adjusting plate 272 extending from a rim of the frame 110 in a direction of the first opening 111 and a hinge 274 configured to rotationally move the adjusting plate 272 in a direction of the door unit 210 of the prescribed product.
Herein, in response to a control signal of the control module, the gap adjusting unit can 270 adjust the gap between the rear surface of the transparent display panel 120 and the front surface of the door unit 210 of the prescribed product.
For instance, a humidity sensor configured to sense humidity within the airgap 180 may be disposed in the frame 110. And, the control module can control the gap adjusting unit 270 by receiving a sensing signal of the humidity sensor.
Namely, if the humidity within the airgap is high, the controller module controls the gap adjusting unit 270 to increase the gap into a maximum gap dl. If the humidity within the airgap is low, the controller module controls the gap adjusting unit 270 to decrease the gap into a minimum gap d2.
Therefore, the present invention prevents the transparent display panel 120 from being adversely affected by humidity, thereby enhancing durability.
Referring to
Herein, an airgap may be formed between a rear surface of the transparent display panel 120 and a front surface of a door unit 210 of a prescribed product.
The reason for this is that as the transparent display panel 120 may be adversely affected by humidity generated due to a temperature difference between the transparent display panel 120 and the door unit 210 of the product, durability of the transparent display panel 120 can be degraded.
Hence, a ventilating unit 135 configured to discharge heat generated from the control module 130 into the space between the rear surface of the transparent display panel 120 and the front surface of the door unit of the prescribed product may be disposed in the second opening of the frame 110.
Herein, the ventilating unit 135 enables air with heat to flow into the space between the rear surface of the transparent display panel 120 and the front surface of the door unit 210 of the prescribed product, thereby removing humidity within the airgap 180.
For instance, a humidity sensor configured to sense humidity within the airgap 180 may be disposed in the frame 110. The control module 130 can control the ventilating unit 135 by receiving a sensing signal of the humidity sensor.
Therefore, the present invention prevents the transparent display panel 120 from being adversely affected by humidity, thereby enhancing durability.
Referring to
Herein, as shown in
For instance, if prescribed beverages are disposed in the cooler, the transparent display panel 120 displays various informations and images (photos, videos, etc.) related to the beverages, which can be utilized for advertisement, public relations and the like.
And, the transparent display device 100 may provide various informations by sensing a user's touch input through an infrared (IR) touch sensor and the like.
In some cases, the transparent display device 100 may include a camera and provide various informations by sensing a user's gesture action through the camera.
Referring to
In doing so, the transparent display panel 120 may enable the goods in the cooler to be viewable through the transmissive region 120b for transmitting light and also enable the goods in the cooler not to be viewable through the non-transmissive region 120a for not transmitting light.
Namely, a user may partially view the goods in the cooler through the transparent display panel 120.
In doing so, the transparent display panel 120 may enable the goods in the cooler to be sequentially viewed as a location the transmissive region 120b for transmitting light moves according to a time.
For instance, in the transparent display panel 120, the transmissive region 120b for transmitting light may move regularly in a predetermined direction or may move irregularly in various directions.
As the transmissive region 120b for transmitting light moves, the user can dynamically view portions of the goods in the cooler so as to be focused on the goods. Therefore, effects of advertisement and public relations are excellent.
Alternatively, the transparent display panel 120 may enable the goods in the cooler to be viewed through the transmissive region 120b for transmitting light and also display various advertisement images related to the goods in the cooler through the non-transmissive region 120 for not transmitting light.
Namely, a user may view the advertisement image related to the goods in the cooler as soon as view the goods in the cooler, through the transparent display panel 120.
Alternatively, the transparent display panel 120 may enable all the goods in the cooler to be viewed through the transmissive region 120b for transmitting light, which corresponds to the whole transparent display panel 120, and also display various advertisement images related to the goods in the cooler.
Alternatively, the transparent display panel 120 may enable all the goods in the cooler to be viewed through the transmissive region 120b for transmitting light, which corresponds to the whole transparent display panel 120, and also display various advertisement images related to the goods in the cooler through the transmissive region 120b at a partially designated location only.
Thus, as shown in
Moreover, referring to
In this case, the transparent display panel 120 may enable the goods in the cooler to be viewed through the transmissive region 120b for transmitting light and also display various advertisement images related to the goods in the cooler through the non-transmissive region 120a for not transmitting light. In doing so, the goods displayed on the non-transmissive region 120a may be limited to the goods viewed through the transmissive region 120b only.
Namely, a user may view the viewable real goods and the advertisement image related to the real goods through the transparent display panel 120.
Accordingly, the present invention achieves simple installation and separation of a display device, facilitation of part replacement and mass production by detachably attaching a frame having a transparent display panel and control module disposed thereon to a front surface of a door unit of a prescribed product.
Moreover, the present invention achieves excellent advertisement and public relations effects of goods within a transparent display device installed product by displaying information and images (photos, videos, etc.) related to the goods.
