FIELD OF THE DISCLOSURE
The present disclosure relates generally to attachable display accessories for portable electronic devices. More particularly, the disclosure relates to rotatable and adjustable display screens that attach to an electronic device.
BACKGROUND
Conventional portable electronic devices, such as laptop computers, are generally provided with a single display screen. Users need to switch among windows on the screen when viewing different graphics or processing different files of data at the same time. This causes inconvenience to the user and does not satisfy user requirements. While attachable display accessories, such as attachable display screens, have been developed, these accessories are bulky, heavy, and are not easily transportable. Indeed, many of the attachable display accessories also have uneven weight distributions due to the placement of the display control electronics in the display screen housing. Because the display screen is heavier than its mount (and often unsupported), the attachable display accessory is more likely to detach from or change the balance of the portable electronic device when in the extended position. Moreover, the attachable display screens currently on the market generally require the use of multiple cords to provide wired connections between the accessory and the portable electronic device to which it is attached.
Accordingly, there remains a need in the art for an attachable display screen that is sturdy, compact, easily transportable, and has a reduced number of wired connections needed for attachment to the portable electronic device.

Referring to FIGS. 1-9, an attachable display screen 100 according to one embodiment of the present disclosure is shown. As illustrated in FIG. 1, the attachable display screen 100 includes a mount 10 operatively attached to a display screen 12. The mount 10 is configured for removable attachment to a surface of a portable electronic device (not shown), such as to a rear surface of a laptop. The mount 10 is operatively attached to the display screen 12 by two hinges-an upper hinge 14a and a lower hinge 14b. The upper and lower hinges 14a, 14b allow the display screen 12 to rotate about the mount 10 to varying positions. The upper and lower hinges 14a, 14b are designed to provide continual resistance throughout the entire range of motion in adjusting the display screen 12, making it possible to deploy the display screen 12 between a closed position in which the display screen 12 is positioned behind the mount 10 and an open position in which the display screen 12 is extended outwardly from the mount 10, as will be described in more detail below.
It is contemplated that the mount 10 and the display screen 12 be ergonomically sized so as to minimize the weight of the attachable display screen 100 and reduce stress placed on the user's electronic device. In one embodiment, the total thickness of the attachable display screen 100 (including the mount 10 and the display screen 12) is about 5 mm to about 20 mm. In another embodiment, the total thickness of the attachable display screen 100 (including the mount 10 and the display screen 12) is about 8 mm to about 18 mm. In still another embodiment, the total thickness of the attachable display screen 100 (including the mount 10 and the display screen 12) is about 8 mm to about 15 mm. In another embodiment, the total thickness of the attachable display screen 100 (including the mount 10 and the display screen 12) is about 5 mm. In yet another embodiment, the total thickness of the attachable display screen 100 (including the mount 10 and the display screen 12) is about 8 mm. In still another embodiment, the total thickness of the attachable display screen 100 (including the mount 10 and the display screen 12) is about 15 mm.
FIGS. 2A and 2B show a front and rear view, respectively, of the mount 10. In the illustrated embodiment, the mount 10 is constructed as a single plate. The plate may be formed of plastic, glass, ceramics, fiber composites, metal such as stainless steel or aluminum, other suitable materials, or a combination of these materials. In one embodiment, the mount 10 is formed of aluminum. In other embodiments, the mounting frame 10 may be formed from multiple separate components, for example, a front plate and a back plate.
As shown in FIG. 2A, the front and back of the mount 10 each include a recess 16. The recess 16 is configured to receive an attachment mechanism located on the surface of the portable electronic device to which the attachable display screen 100 is to be mounted. In one embodiment, one or more magnets 72 (shown in FIG. 6A) are housed within the interior of the recess 16. In this embodiment, the attachment mechanism on the portable electronic device can be received within the recess 16 and securely attach to the mount 10 via a magnetic connection. In one embodiment, the magnets 72 may be embedded within the interior of the recess 16 such that they are not visible from the exterior of the mount 10. In some embodiments, as illustrated in FIGS. 2A and 2B, a cover 18 may be positioned over the magnets. Any number of magnets may be housed within the recess 16. In one embodiment, a single magnet may be housed within the recess 16. In another embodiment, more than one magnet may be housed within the recess 16. For example, the recess 16 may include two, three, four, five, six, seven, eight, nine, or ten magnets housed therein. In a preferred embodiment, the recess 16 includes five magnets housed therein to ensure a strong connection to the surface of the portable electronic device. In some embodiments, as will be described in more detail below, one or more closing magnets 74 (shown in FIG. 6A) may also be embedded within the mount 10 at an end opposite the recess 16. This helps ensure that the mount 10 remains attached to the display screen 12 when in the stored or closed position.
As shown in FIGS. 2A and 2B, both the front and the back of the mount 10 include the recess 16 so that both sides of the mount 10 can attach to the surface of the portable electronic device depending on the desired position of the display screen 12. For example, when the display screen 12 is in the open position, the attachment mechanism on the surface of the portable electronic device can be received within the recess 16 on the front of the mount 10. However, when the display screen 12 is closed, the mount 10 may be flipped such that the recess 16 on the back of the mount 10 is attached to the attachment mechanism on the surface of the portable electronic device so that the display screen 12 can be placed face down against the back of the portable electronic device.
In the illustrated embodiment, the shape of the mount 10 is that of a sideway U-shape and the shape of the recess 16 is that of a square. However, the shape of the mount 16 and the recess 16 may vary so long as the components allow for a secure attachment to the portable electronic device. Moreover, while the use of magnets has been described herein as an exemplary means for attaching the mount 10 to the portable electronic device, one of ordinary skill in the art will recognize that that the mount 10 may be secured to the electronic device by any suitable means including, but not limited to, by hooks, adhesives, screws, pins, projections, or snap catch elements.
In some embodiments, as illustrated in FIGS. 2A and 2B, the recess 16 may include a sighting hole 20. The sighting hole 20 is located in the center of the cover 18 such that any magnets embedded within the recess 16 are positioned around it. The sighting hole 20 can be used as an alignment aid to accurately position the recess 16 over the attachment mechanism located on the surface of the portable electronic device. For example, a user can align the sighting hole 20 with an indicator, such as a symbol, on the attachment mechanism so that the attachment mechanism can be properly aligned with and received within the recess 16 for a secure connection.
In further embodiments, as shown in FIG. 3, the mount 10 may include a groove 22. The groove 22 extends along the outer perimeter of the end of the mount 10 opposite the hinges 14a, 14b. The groove 22 allows the user to grip and remove the mount 10 from the portable electronic device with ease. The mount 10 may also include a lip 24, as illustrated in FIG. 3. As will be described in more detail below, the lip 24 ensures that the mount 10 is pressed against the display screen 12 when closed and in the stored position.
In some embodiments, the mount 10 also houses a control board 70 (shown in FIG. 6A), such as a printed circuit board, that provides power to the attachable display screen 100 and communicates with both the display screen 12 and the portable electronic device to which the attachable display screen 100 is attached. The control board 70 may be any type of integrated circuit that is operable to transmit data to the display screen 12 and the portable electronic device. The present disclosure contemplates that the control board 70 be located on the interior of the mount 10 and adjacent to the recess 16. By housing the control board 70 in the mount 10 (rather than in the display screen), the display screen 12 can be lighter and thinner, which provides a better and more even weight distribution of the attachable display screen 100 when it is in use.
To establish communication between the control board 70 in the mount 10 and the display screen 12, an electrical connector, such as a cable (not shown), can operatively connect the control board 70 to the display screen 12. The electrical connector can be fed through the interior of the mount 10 and through either of the hinges 14a, 14b to connect the control board to electronics in the display screen 12.
In some embodiments, the mount 10 may also include an external communications port 26 to establish communication between the control board and the portable electronic device, as shown in FIG. 4. The external communications port 26 is operatively connected to the control board. As will be described in more detail below, the external communications port 26 is configured to receive a wired connection from the portable electronic device to establish communication.
FIGS. 4A and 4B show a torque hinge 52 that can be used for the hinges 14a, 14b according to one embodiment of the present disclosure. As shown in FIG. 4A, the torque hinge 52 includes a first connector 54 that is configured for attachment to an interior portion of the display screen 12 and a second connector 56 that is configured for attachment to an interior portion of the mount 10. The first connector 54 may include a plurality of apertures 58 through which fasteners may be inserted for attaching the first connector 54 to the display screen 12. The second connector 56 may include a plurality of apertures 60 through which fasteners may be inserted for attaching the second connector 56 to the mount 10. A hinge mechanism 62 may be operatively connected to the first connector 54 and the second connector 56, which allows the display screen 12 to rotate about the mount 10 to varying positions.
As shown in FIG. 4B, a cover 64 may be placed over the hinge mechanism 62. In this embodiment, the electrical connector can be fed through the interior of the mount 10 and through the cover 64 of the torque hinge 52 to connect the control board in the mount 10 to electronics in the display screen 12. In one embodiment, the cover 64 may include a cable passing portion which is a space in which the electrical connector can pass through the torque hinge 52.
For example, the cable passing portion may be a space on the interior portion of the cover 64 that is located below the hinge mechanism 62 and above the bottom portion of the cover 64 so that the cable does not interfere with the rotation of the torque hinge 52. In this embodiment, the cable can loop under the lower portion of the hinge mechanism 62 without interfering with the rotation of the hinge.
FIGS. 5A and 5B show a front and rear view, respectively, of the display screen 12. As shown in FIGS. 5A and 5B, the display screen 12 includes a screen portion 28 housed within an outer panel 30. The outer panel 30 includes the hinges 14a, 14b attached thereto for rotating the display screen 12 about the mount 10. The outer panel 30 may also include a bump out portion 32. The bump out portion 32 is configured to rest upon a back surface of the portable electronic device when the display screen 12 is closed and in the stored position to form a secure connection and prevent the display screen from unintentionally opening. In some embodiments, the bump out portion 32 may also house one or more controls or buttons for adjusting the settings of the screen portion 28. For example, the bump out portion 32 may include one or more buttons for adjusting the brightness of the screen portion 28.
As illustrated in FIG. 5B, the rear of the outer panel 30 may include an indentation 34 configured for receiving the mount 10 therein. In this embodiment, the indentation 34 has a shape complementary to the shape of the mount 10 so that the display screen 12 can lie flat against the mount 10 when the display screen 12 is configured in the presentation position, as shown in FIG. 9. In the illustrated embodiment, the shape of the indentation 34 is that of a sideway U-shape to complement the shape of the mount 10 shown in FIGS. 1 and 2A-2B. In further embodiments, the outer panel 30 may also include one or more steel plates (not shown) embedded within the interior of the outer panel 30 and positioned adjacent to the indentation 34. The steel plates are configured to align with the closing magnets 74 (shown in FIG. 6A) embedded within the mount 10 to help keep the display screen 12 tightly secured to the mount 10 when closed and in the stored position.
The screen portion 28 may be any type of external electronic display including, but not limited to, an electroluminescent (ELD) display, liquid crystal display (LCD), light emitting diode (LED) display (e.g., organic light emitting diode (OLED) or microLED), plasma display panel (PDP), quantum dot (QLED) display, and a touch screen display. In a preferred embodiment, the screen portion 28 is an LCD display. In some embodiments, the screen portion 28 may also have a tempered glass screen protector installed thereon for protection.
FIG. 6 shows an exemplary mechanism for securing the attachable display screen 100 to a portable electronic device 200. As discussed above, the attachable display screen 100 is configured to be removably mounted onto a surface of the portable electronic device 200 to provide the user with an additional display monitor. In this embodiment, the portable electronic device 200 includes an attachment mechanism configured for attaching to the mount 10 on the attachable display screen 100. In one embodiment, the attachment mechanism is a sticker 36 configured to magnetically attach to the magnets embedded within the recess 16. For example, the sticker 36 may be made of metal or steel. As illustrated in FIG. 6, a first side of the sticker 36 is configured to secure to a surface of the portable electronic device 200 and the opposite side is configured to be received within the recess 16. The sticker 36 can be attached to the surface of the portable electronic device 200 using a fastener 38. In one embodiment, the fastener 38 may be an adhesive, such as a pressure sensitive adhesive or double-sided tape. As illustrated in FIG. 6, two fasteners 38 are used to attach the sticker 36 to the surface of the portable electronic device 200. However, as will be appreciated by those skilled in the art, any number of fasteners 38 may be used to attach the sticker 36 to the surface so long as a secure connection is formed.
The recess 16 is configured to receive the sticker 36 attached to the surface of the portable electronic device 200. In this embodiment, the sticker 36 may securely connect to the magnets that are embedded within the recess 16. The magnets embedded within the recess 16 attach to the sticker 36 by a magnetic force, which provides a secure connection onto the portable electronic device 200 and prevents the attachable display screen 100 from moving during use (but is still removable with sufficient force). In some embodiments, the sticker 36 may be complementary in shape to the recess 16 such that the sticker 36 fits securely within the recess 16. In addition, while a single sticker 36 is shown in FIG. 6, any number of stickers 36 may be used so long as the stickers fit securely within the recess 16.
The attachable display screen 100 is configured to be communicatively coupled to the portable electronic device 200 via a wired connection 40.

In this aspect, the display screen 12 is positionable in an extended position thereby allowing viewing of both a screen 44 of the portable electronic device 200 and the display screen 12. As shown in FIGS. 8A and 8B, when the attachable display screen 100 is in the open or extended position, the recess 16 on the front of the mount 10 is magnetically engaged with the sticker 36 positioned on the back of the portable electronic device 200. In this embodiment, the user can transition between the closed position (shown in FIG. 7) and the open position (shown in FIGS. 8A and 8b) by detaching the mount 10 from the sticker 36 on the back of the portable electronic device 200, flipping the mount 10 about 180 degrees such that the recess 16 on the front of the mount 10 is aligned with the sticker 36, and engaging the recess 16 on the front of the mount 10 with the sticker 36.
The display screen 12 is configurable to swing out from behind the portable electronic device 200 so that a user can utilize a second display screen when the attachable display screen 100 is mounted onto the portable electronic device 200. The display screen 12 is configured to swing from a closed position, as illustrated in FIG. 7, to an open or extended position, as illustrated in FIGS. 8A and 8B, via the hinges 14a, 14b. In some embodiments, the hinges 14a, 14b allow the display screen 12 to rotate about a vertical axis aa relative to the portable electronic device 200 in rotation directions R1 and R2 (which are opposite to each other). When rotated in direction R1, the display screen 12 may be angled toward the user. The display screen 12 can be rotated in direction R1 until the display screen 12 interferes with the screen 44 of the portable electronic device 200. When rotated in direction R2, the display screen 12 may be angled away from the user. In other words, the hinges 14a, 14b allow the display screen 12 to adjust from a plane-like display as shown in FIG. 7 to an extended display state as shown in FIGS. 8A and 8B which allows the user to obtain a preferable view angle range and visual effect. In some embodiments, the display screen 12 has a maximum degree of rotation of about the vertical axis aa of about 270 degrees.
The hinges 14a, 14b are designed to provide continual resistance throughout the entire range of motion in adjusting the display screen 12, making it possible to easily position the display screen 12 securely at a desired angle. Any suitable torque hinge or constant torque friction hinge may be used in accordance with the present disclosure. The display screen 12 may also be opened to the left or the right of the screen 44 of the portable electronic device 200 depending on the user's preference. In the illustrated embodiment, the display screen 12 is deployed to the right. However, the mount 10 may be flipped or inverted so that the display screen 12 is deployed to the left.
FIG. 9 is a rear perspective view of the portable electronic device 200 having the attachable display screen 100 mounted thereon in a presentation position. As can be seen in FIG. 9, the hinges 14a, 14b allow for the display screen 12 to fully rotate in direction R2 along vertical axis aa to an angle of 180 degrees such that the display screen 12 can be viewed from the rear of the portable electronic device 200. This allows for the display screen 12 to be deployed in a presentation position for viewing by another user opposite the user positioned in front of the portable electronic device 200.
FIG. 10 shows the attachable display screen 100 having a hinge mechanism according to another embodiment of the present disclosure. In this embodiment, the mount 10 is operatively attached to the display screen 12 by a torque hinge 46 having a pivot point that allows the display screen 12 to swivel a full 360 degrees about the mount 10. The torque hinge 46 makes it possible to not only deploy the display screen 12 between the closed and open/extended positions (like the embodiment described above with respect to FIGS. 1-9), but also securely tilt the display screen 12 to any desired angle. The ability of the display screen 12 to swivel about the mount 10 also dispenses of the need for the recess on the back of the mount 10. That is, the display screen 12 can be opened and closed without the need to flip the configuration of the mount 10.
FIGS. 11A and 11B show a front and rear view, respectively, of the display screen 12 with the torque hinge 46 attached thereto. As shown in FIGS. 11A and 11B, the torque hinge 46 is formed of an elongated structure 48 having two projections 50a, 50b protruding from each end. The projections 50a, 50b are configured for engagement with corresponding holes disposed on the mount 10. The projections 50a, 50b serve as hinges that allow for rotation of the display screen 12 about the vertical axis aa, as will be described in more detail below. The torque hinge 46 is operatively connected to the display screen 12 at a pivot point (not shown). The pivot point allows for complete vertical adjustability of the display screen 12 about the mount 10. That is, the torque hinge 46 allows for the display screen 12 to swivel or tilt upward and downward relative to the screen 44 of the portable electronic device 200 upon which the attachable display screen 100 is mounted. The pivot point also allows the user to adjust the horizontal viewing angle of the display screen 12. In some embodiments, the torque hinge 46 allows for the display screen 12 to swivel 360 degrees about the pivot point.
In some embodiments, when the display screen includes the torque hinge 46 shown in FIG. 10 and FIGS. 11A-11B, the electrical connector can be fed through the torque hinge 46 to connect the control board in the mount 10 to electronics in the display screen 12. For example, in one embodiment, the electrical connector can be fed around the pivot point of the torque hinge 46 so as not to interfere with the rotation of the torque hinge 52.
While the torque hinge 46 has been described herein as illustrated in FIGS. 11A and 11B, any suitable torque hinge or constant torque friction hinge may be used in accordance with the present disclosure. In addition, any number of torque hinges may be utilized with the attachable display screen 100 to provide adjustability. For instance, the attachable display screen 100 may include two or more separate torque hinges. In another embodiment, the attachable display screen 100 may include three or more separate torque hinges.
FIG. 12 is a rear perspective view of the portable electronic device 200 having the attachable display screen 100 shown in FIG. 10 mounted thereon and in the closed position. When the attachable display screen 100 is in the closed position, the recess 16 on the front of the mount 10 is magnetically engaged with the sticker 36 positioned on the back of the portable electronic device 200 such that the screen portion 28 lies flat against the mount 10 while the rear of the outer panel 30 faces outwardly. In this embodiment, the steel plate(s) embedded within the interior of the outer panel 30 are aligned and magnetically engaged with the closing magnets 74 embedded within the mount 10 to help keep the display screen 12 tightly secured.
FIGS. 13A and 13B are front and rear perspective views, respectively, of the portable electronic device 200 having the attachable display screen 100 shown in FIG. 10 mounted thereon and in the open or extended position. With the use of the torque hinge 46, the display screen 12 is configurable to swing out from behind the mount 10 (when in the closed position) so that a user can utilize a second display screen when the attachable display screen 100 is mounted onto the portable electronic device 200. The display screen 12 is configured to swing from a closed position, as illustrated in FIG. 12, to an open or extended position, as illustrated in FIGS. 13A and 13B, via the torque hinge 46. The display screen 12 may be opened to the left or the right of the screen 44 of the portable electronic device 200 depending on the user's preference. In the illustrated embodiment, the display screen 12 is deployed to the right. However, the mount 10 may be flipped or inverted so that the display screen 12 is deployed to the left.
Like the attachable display screen 100 shown in FIGS. 8A and 8B, the display screen 12 can rotate about the vertical axis aa relative to the portable electronic device 200 in rotation directions R1 and R2. However, with the use of the torque hinge 46, the display screen 12 can also fully rotate about a horizontal axis bb. The user can adjust the display screen 12 by tilting the display screen 12 upward or downward. When rotated in direction R3, the display screen 12 may be tilted downward. When rotated in direction R4, the display screen 12 can be titled upward. In this embodiment, the display screen 12 can be rotated in direction R3 or direction R4 in a complete circle (i.e., 360 degrees).
FIG. 14 is a rear perspective view of the portable electronic device 200 having the attachable display screen 100 shown in FIG. 10 mounted thereon in a presentation position.
In this embodiment, the user may desire to rotate the display screen 12 to an angle of 180 degrees and swing the display screen 12 to the closed position such that the display screen 12 can be viewed from the rear of the portable electronic device 200. This allows for the display screen 12 to be deployed in a presentation position for viewing by another user opposite the user positioned in front of the portable electronic device 200.
FIG. 15 is a front perspective view of a kickstand 76 attached to the mount 10 according to one embodiment of the present disclosure. The kickstand 76 can provide support when the attachable display screen 100 is in an open or extended position. In some embodiments, as shown in FIG. 15, the kickstand 76 is rotatably attached to the mount 10. The kickstand 76 can rotate to various positions to provide support for the attachable display screen 100. For instance, when the kickstand 76 is rotated away from the mount 10, the kickstand 76 can rotate to an angle of up to about 100 degrees while supporting the attachable display screen 100. In another embodiment, the kickstand 76 can rotate to an angle of about 10 degrees to about 90 degrees while supporting the attachable display screen 100. In still another embodiment, the kickstand 76 can rotate to an angle of about 20 degrees to about 80 degrees while supporting the attachable display screen 100. In yet another embodiment, the kickstand 76 can be rotated to an angle of about 90 degrees to provide optimal support. When in the open position, the kickstand 76 can sufficiently support the weight of the attachable display screen 100.
In one embodiment, the kickstand 76 is operatively attached to the mount 10 at an upper connection point 78 and a lower connection point 80. The upper and lower connection points 78, 80 allow for the kickstand 76 to rotate away from the mount 10 and provide constant resistance throughout the entire range of rotation, enabling a user to position the kickstand 76 at any desired angle. The kickstand 76 can be attached to the mount 10 at the upper and lower connection points 78, 80 using any suitable attachment mechanism. For example, the kickstand 76 may be attached to the mount 10 via screws, pins, or projections.
In another embodiment, the kickstand 76 may be releasably attached to the mount 10. In this embodiment, the kickstand 76 may be opened from the mount 10 via spring activation. In still another embodiment, the kickstand 76 may be releasably attached to the mount 10 via a magnetic force. In this embodiment, a magnet (not shown) may be positioned on a side of the mount 10 opposite the hinge(s). The magnet can provide a secure connection between the kickstand 76 and the mount 10 when not in use but is still able to be opened with sufficient force. In yet another embodiment, the kickstand 76 may be releasably attached to the mount 10 by a ratcheting mechanism. In this embodiment, the ratcheting mechanism can lock the kickstand 76 in place on the mount 10 until the kickstand 76 is opened.
As shown in FIG. 15, the kickstand 76 has a cut-out U-shape so that the kickstand 76 may be integral with and forms a portion of the mount 10 when in the closed position. The cut-out shape improves the portability and compactness of the kickstand 76 and reduces the impact on the internal and external volume and size of the attachable display screen 100. In this embodiment, the kickstand 76 can be stored within the mount 10 when the attachable display screen 100 is attached to a surface of the portable electronic device 200. In one embodiment, the size and shape of the kickstand 76 conforms to the size and shape of the mount 10 such that the kickstand 76 does not protrude from the plane formed by the mount 10 when in the closed position. For instance, the shape and size of the kickstand 76 conforms to the contour of the mount 10 such that the kickstand 76 is integral with the mount 10. While the kickstand 76 has been illustrated herein as a cut-out U-shape, one of ordinary skill in the art will recognize that the kickstand 76 may be formed into a variety of shapes and sizes.
In some embodiments, the attachable display screen 100 may include other internal components including, but not limited to, electrical components such as display driver circuitry, one or more batteries, sensors, microphones, speakers, integrated circuits, microprocessors, power management units, radio-frequency transceiver circuitry, baseband processor circuitry, discrete components such as capacitors, resistors, and inductors, switches, vibrators, connectors, printed circuit boards, wires, transmission lines, and other electrical devices.
