ELECTRONIC DEVICE SYSTEM WITH AN EMBEDDED DISPLAY UNIT

TECHNICAL FIELD

Embodiments described herein generally relate to an embedded display unit for an electronic device.

BACKGROUND

End users have more electronic device choices than ever before. A number of prominent technological trends are currently afoot (e.g., more computing devices, duel displays, more detachable displays, etc.), and these trends are changing the electronic device landscape. One of the technological trends is an electronic device with two displays where one display is a main display and the other display is a small screen flat on the chassis or shell of the electronic device. When the electronic device is in a closed clamshell configuration, to access either display at a comfortable angle and use the electronic device, the electronic device needs to be opened. Hence, there is a challenge in providing access to use and interact with the electronic device without having to open the electronic device from a closed clamshell configuration.

Another of the technological trends is a convertible or hybrid laptop. The convertible laptop is any type of computer system that has a detachable display and can essentially function as either a laptop or a tablet computer. In some instances, once the display is detached, some users discover that the display can be heavy and the size of the display can be prohibitive from using as a tablet. Hence, there is a challenge in providing an electronic device that allows a display to be detached from the electronic device and then used as a tablet or a standalone device.

Example Embodiments

The following detailed description sets forth example embodiments of apparatuses, methods, and systems relating to detachable unit configurations for an electronic device. Features such as structure(s), function(s), and/or characteristic(s), for example, are described with reference to one embodiment as a matter of convenience; various embodiments may be implemented with any suitable one or more of the described features.

FIG. 1A is a simplified orthographic view illustrating an embodiment of an electronic device 10a in an open clamshell mode configuration in accordance with one embodiment of the present disclosure. Electronic device 10a may include a display portion 12a and a keyboard portion 14a. Display portion 12a can include a main display 16. Keyboard portion 14a can include a keyboard 18.

In one or more embodiments, electronic device 10a (and 10b and 10c discussed below) is a notebook computer or laptop computer. In still other embodiments, electronic device 10a (and 10b and 10c discussed below) may be any suitable electronic device having a display such as a mobile device, a tablet computer and/or a tablet device (e.g., i-Pad™), Phablet™, a personal digital assistant (PDA), a smartphone, an audio system, a movie player of any type, a computer docking station, etc. In yet another embodiment, most of the electronics (e.g., processor, memory, etc.) for electronic device 10a reside in keyboard portion 14a. Main display 16 can be a liquid crystal display (LCD), organic light-emitting diode (OLED), or some other type of display. Main display 16 may also be a touchscreen display. In an embodiment, electronic device 10a may contain a camera, a microphone, and speakers.

Turning to FIG. 1B, FIG. 1B is a simplified orthographic view illustrating an embodiment of an electronic device 10a in accordance with one embodiment of the present disclosure. Electronic device 10a may include display portion 12a and keyboard portion 14a. Display portion 12a may include a secondary display unit 20 and a hinge 34. Secondary display unit 20 may include a secondary display 22. Hinge 34 can facilitate an electrical and physical connection of secondary display unit 20 to display portion 12a. In an embodiment, hinge 34 can define an axis of rotation that is shared between display portion 12a and secondary display unit 20. Secondary display unit 20 can allow a user to use (i.e., access, interact with, interface with, work on, etc.) electronic device 10a. Using hinge 34, secondary display unit 20 can be rotated away from display portion 12a which can allow a more comfortable angle for viewing and interacting with secondary display unit 20 than just a small screen flat on the chassis or shell of electronic device 10a.

Secondary display 22 can be a liquid crystal display (LCD), organic light-emitting diode (OLED), or some other type of display. In an embodiment, secondary display unit 20 may contain a battery and various electronics (e.g., processor, memory, etc.) to allow secondary display unit 20 to operate as a standalone tablet or a handheld device. Secondary display 22 may also be a touchscreen display. When secondary display unit 20 is connected to display portion 12a, secondary display 22 can display images displayed or shown on main display 16, images that are complimentary to images displayed on main display 16, or can display images independently of main display 16.

Note that, although in certain embodiments electronic device 10a is configured to operate in a closed configuration in which the main display is not accessible and secondary display unit 20 is accessible, other embodiments account for various different configurations. Consider an example in which a user is able to check email sitting on a train using secondary display unit 20, while electronic device 10a (e.g., a laptop) is closed. In other embodiments, the primary and secondary screens can readily be used at the same time. For example, if a user is presenting to someone across from the user (at a table, in a coffee shop, etc.), the user can turn the electronic device (e.g., a laptop) such that the main screen faces the counterparty, and the user presenting could see what the counterparty sees by using the small screen display of secondary display unit 20. Further, the presenter/user can control the big screen view and one or more interactions from the small screen of secondary display unit 20.

Note also that the secondary screen of secondary display unit 20 can both operate as a secondary screen that is independent from the primary screen (showing different content, having different functionality, having different applications, etc.), or secondary display unit 20 can have similar characteristics. In addition, the secondary screen of secondary display unit 20 can operate as a replacement screen that operates instead of (or in conjunction with) the first screen using the same content and functionality.

Turning to FIG. 1C, FIG. 1C is a simplified orthographic view illustrating an embodiment of an electronic device 10a in accordance with one embodiment of the present disclosure. As illustrated in FIG. 1C, electronic device 10a is in a close clamshell configuration and secondary display unit 20 is flat on the chassis or shell of electronic device 10a. Main display 16 is not accessible.

Turning to FIG. 1D, FIG. 1D is a simplified orthographic view illustrating an embodiment of an electronic device 10a in a closed clamshell configuration in accordance with one embodiment of the present disclosure. When electronic device 10a is in a closed clamshell configuration, the user does not have access to main screen 16. As illustrated in FIG. 1D, secondary display unit 20 has been rotated about hinge 34 and away from display portion 12a. This allows the user to use secondary display unit 20 at a more comfortable angle than just flat on the chassis or shell to access and interact with electronic device 10a when electronic device 10a is in a closed clamshell configuration. In at least one embodiment, the hinge (operating in conjunction with any type of spring-loaded mechanism, magnet system, etc.) can facilitate a preset angle of the secondary display unit for viewing (e.g., a comfortable angle for viewing from the perspective of the user) upon receiving a downward force on any portion of the electronic device (e.g., a surface of the secondary display unit). Other embodiments could include a simple latch mechanism, or any suitable release that would assist in raising the secondary display unit to a suitable level.

Turning to FIG. 1E, FIG. 1E is a simplified schematic diagram illustrating an embodiment of electronic device 10a in a detach mode, separated into two segments. As illustrated in FIG. 1E, secondary display unit 20 has been separated from display portion 12a, creating a base device 56a and leaving a secondary display unit cavity 24 in display portion 12a. Secondary display unit cavity 24 can help hold or secure secondary display unit 20 to display portion 12a. Hinge 34 may include a display interconnect 26. Secondary display unit 20 may include a secondary display unit interconnect 28. Display interconnect 26 may be a printed circuit board (PCB) interconnector.

Using display interconnect 26, when secondary display unit 20 is connected to display portion 12a, an electrical current and signals can be passed between display portion 12a and secondary display unit 20 to recharge an on-board battery or capacitor, power any number of items (e.g., secondary display 22, wireless communication circuitry such as a wireless module, a camera, speakers, etc.), and provide a communication path between display portion 12a and secondary display unit 20. In other examples, electrical current and signals can be passed through a plug-in connector (e.g., whose male side protrusion connects to display portion 12a and whose female side connects to secondary display unit 20 or vice-verse) or a wireless connector (e.g., WiFi, Bluetooth, Wireless Display (WiDi), etc.). Note that any number of connectors (e.g., Universal Serial Bus (USB) connectors (e.g., in compliance with the USB 3.0 Specification released in November 2008), Thunderbolt™ connectors, a non-standard connection point such as a docking connector, etc.) can be provisioned in conjunction with electronic device 10a. [Thunderbolt™ and the Thunderbolt logo are trademarks of Intel Corporation in the U.S. and/or other countries.]. Virtually any other electrical connection methods could be used and, thus, are clearly within the scope of the present disclosure

In general terms, when electronic device 10a is in a closed clamshell configuration, hinge 34 can be used to rotate secondary display unit 20 away from display portion 12a which would allow a user to use or access electronic device 10a without opening up electronic device 10a. When secondary display unit 20 is removed from display portion 12a, secondary display unit 20 can function as a computer (e.g., notebook computer, laptop, tablet computer or device), phablet, a cellphone, a personal digital assistant (PDA), a smartphone, an audio system, a movie player of any type, or other device that includes a circuit board coupled to a plurality of electronic components (which includes any type of components, elements, circuitry, etc.). Secondary display unit 20 can include a battery and various electronics (e.g., processor, memory, etc.) to allow secondary display unit 20 to function as a standalone device. In another embodiment, secondary display unit 20 may include a camera, a microphone, and speakers. In yet another embodiment, secondary display unit 20 may include very little computing and/or storage components so secondary display unit 20 can be really thin with a battery occupying almost the entire area of secondary display unit 20. When secondary display unit 20 is separated from display portion 12a, secondary display 22 can display images shown on main display 16, images that are complementary to images shown on main display 16, or can display images independently of main display 16.

For purposes of illustrating certain example features of electronic devices 10a, 10b, and 10c, the following foundational information may be viewed as a basis from which the present disclosure may be properly explained. Some form factors for clamshell computer include a second display on the outside of a chassis or shell of the clamshell computer where the second display is located on the opposite side of a main display. However, the secondary display is completely integrated and fused to the chassis or shell and a user has to hold the clamshell computer to interact with the secondary display. In at least one example embodiment discussed herein, a hinge can be used to rotate secondary display unit away from the chassis or shell of the clamshell computer which would allow a user to use or access the secondary display and the clamshell computer without opening up the clamshell computer from a closed clamshell configuration.

In addition, with the recent touch optimized operating system (OS) release for tablets, convertible laptops have become more popular. The convertible laptops can be configured such that the entire display can be unhinged and removed from the base or keyboard portion of the convertible laptop. However, after the display is removed and is in a tablet configuration, the display can be heavy and the size of the display can be prohibitive from using as a tablet. If the display were smaller to accommodate use in the tablet configuration, then when the display is reattached to the base or keyboard portion to create a clamshell configuration, the display may be too small to use as a display in the clamshell configuration. In at least one example embodiment discussed herein, an electrical device can be configured to allow a secondary display of the electronic device to be removable. The secondary display can be separate from the main display and, further, be configured to operate as a standalone tablet or a handheld device.

Particular embodiments described herein provide for an electronic device, such as a notebook computer, laptop, cellphone, or other mobile device that includes a circuit board coupled to a plurality of electronic components (which includes any type of components, elements, circuitry, etc.). The electronic device may also include a secondary display unit (that includes a secondary display) which can be docked, attached, or connected to the electronic device using a hinge. When docked or connected, the secondary display unit can be flush with the surface of the electronic device so the electronic device looks and functions like a dual display electronic device. In addition, using the hinge, the secondary display unit may be raised up or rotated outward from the electronic device to an angle that allows a user to interact with the secondary display unit. For example, if the user has the electronic device in a closed clamshell configuration, the display unit can be raised at an angle to allow the user to view and interact with the detachable display.

In addition, the secondary display unit can be undocked, detached, or removed from the electronic device and the secondary display unit can function or operate like tablet or handheld electronic device. In an embodiment, the secondary display unit may include just a display, a battery, wireless capability, and only the necessary electronics for the secondary display unit to function as a standalone tablet or handheld device. The secondary display unit may use WiFi, Bluetooth, WiDi, etc. to communicate with a network or other electronic devices. The size of the secondary display unit is only limited by functionality (e.g., too small and the detachable display may not function as a standalone device) and the size of the electronic device (e.g., the detachable display may not be bigger than the electronic device). For example, the size of the secondary display unit can vary anywhere from the size of a small digital music player up to the size of the chassis or main body of electronic device.

Turning to FIG. 2, FIG. 2 is a simplified block diagram illustrating an embodiment of electronic device 10a in accordance with one embodiment of the present disclosure. Secondary display unit 20 may include secondary display unit interconnect 28 and a wireless module 30.
