Various other apparatuses, systems, methods, etc., are also disclosed.

DETAILED DESCRIPTION

The following description includes the best mode presently contemplated for practicing the described implementations. This description is not to be taken in a limiting sense, but rather is made merely for the purpose of describing general principles of various implementations. The scope of invention should be ascertained with reference to issued claims.

FIG.1shows an example of a device100that includes a keyboard housing120and a display housing140that are pivotable with respect to each other via movement about one or more hinges132-1and132-2(e.g., hinge assemblies). The device100may be a system such as, for example, a computing system (e.g., an information handling device, etc.).

As an example, the device100may include one or more processors112, memory114(e.g., one or more memory devices), one or more network interfaces116, and one or more power cells118. Such components may be, for example, housed within the keyboard housing120, the display housing140, or the keyboard housing120and the display housing140.

As shown in the example ofFIG.1, the keyboard housing120includes a keyboard124with keys125and the display housing140includes a display141with a display surface144. In such an example, the keyboard124is defined in a first Cartesian coordinate system as having a width along an x-axis (x1), a depth along a y-axis (y1) and a height or thickness along a z-axis (z1) that extends in a direction outwardly away from touch surfaces of keys125of the keyboard124and the display141is defined in a second Cartesian coordinate system as having a width along an x-axis (x2), a depth along a y-axis (y2) and a height or thickness along a z-axis (z2) that extends in a direction outwardly away from the viewing surface144of the display141. As an example, a coordinate system may be right-handed or left-handed. In various examples, a footprint may be defined by an area such as an area in an x,y-plane.

As shown in the example ofFIG.1, the one or more hinges132-1and132-2pivotably connect the keyboard housing120and the display housing140for orienting the display housing140with respect to the keyboard housing120. For example, orientations may include orientations definable with respect to an axis (e.g., or axes) such as the axis ζ and an angle Φ about that axis.

FIG.1shows some examples of orientations101,103,105,107and109. The orientations101,103,105,107and109may correspond to orientations of a clamshell computing system. The orientation101may be a notebook orientation where the angle Φ is about 90 degrees or more (e.g., or optionally somewhat less than about 90 degrees depending on position of a user, etc.). As shown, for the orientation101, a user may use a finger or fingers of one or both hands to depress keys125of the keyboard124(e.g., touch typing), for example, while viewing information being rendered to the display141of the display housing140(e.g., using the one or more processors112, the memory114, etc. that may be included in the keyboard housing120, the display housing140or both).

As an example, the keyboard housing120may include a frontal surface122and may include a touch input surface123(e.g., of a touch input device such as a touchpad). As an example, the keyboard124may include one or more other input devices (e.g., a control stick, etc.). As an example, the frontal surface122may be a surface suitable for resting a palm or palms of a hand or hands. For example, as shown inFIG.1, the touch input surface123can be defined by x and y dimensions where a left palm rest surface is to the left of the touch input surface123and where a right palm rest surface is to the right of the touch input surface123. In such an example, the left and right palm rest surfaces may be defined by respective x and y dimensions as well as a spacing therebetween. Where a device does not include a touch input surface such as the touch input surface123, the frontal surface122may extend in the y direction approximately from a left side of the keyboard housing120to a right side of the keyboard housing. Such a surface can be a left and right palm rest surface.

A palm rest surface can allow a user to rest a palm or palms while the user may type (e.g., touch type) using keys of a keyboard that is part of a keyboard housing. For example, a user can rest a palm on a palm rest surface while using one or more finger tips (e.g., or finger pads) to touch keys to thereby instruct a computing system to receive input instructions. In such an example, the keys of the keyboard may be depressible keys. A depressible key may include a spring mechanism that allows the key to be, responsive to finger applied force, depressed a distance in the z direction of the Cartesian coordinate system of a keyboard housing to a level that may be a maximum depression level where, upon release of the force, the key may then return to an undepressed level.

As to the orientation103, it may correspond to a display orientation for viewing the display141where the keyboard124faces downward and the device100is supported by the keyboard housing120(e.g., by a rim about the keyboard124, the frontal surface122, etc.). As to the orientation105, it may correspond to a “tent” orientation where the display141faces outwardly for viewing on one side of the tent and the keyboard124of the keyboard housing120faces outwardly on the other side of the tent.

The orientation107may be a tablet orientation where the angle Φ is about 360 degrees such that a normal outward vector N1of the keyboard124of the keyboard housing120(e.g., normal to an x1,y1-plane) and a normal outward vector N2of the display141of the display housing140(e.g., normal to an x2,y2-plane) are oriented in oppositely pointing directions, pointing away from each other; whereas, in contrast, for a closed orientation of the device100(e.g., where the angle Φ is about 0 degrees), the vectors N1and N2would be pointing toward each other.

In the orientation107, the keyboard124has its keys125pointing outwardly in the direction of the vector N1. Where the keys125are depressible keys, when a user grasps the device100, the keys125may be contacted by the users hand or hands. A user may perceive the springiness of the keys125as being somewhat undesirable. For example, springy keys may interfere with a user's ability to comprehend or sense force that is sufficient to grasp the device100, which may cause the user to grasp too lightly or to grasp too strongly, which may possibly impact integrity of the keys (e.g., springs, spring-mechanisms, contacts, etc.). Further, if the user repositions her hand or hands, the user may experience the springiness again. In contrast, a surface without such depressible keys may have a more even feel to a user and may be less distracting. An arrangement that allows for such a surface may include a single hinge that allows for pivoting a keyboard housing with respect to a display housing such that keys of the keyboard housing can be oriented to face a back side of a display housing (a side opposite the display). In such an approach, a user may spin the keyboard housing by 180 degrees about a central axis of the single hinge (e.g., an axis orthogonal to the axis and then rotate the keyboard housing such that the keys face the back side of the display in a folded orientation. In such an example, a single centrally located hinge provides symmetry such that a computing system can be aligned in a clamshell closed orientation and a tablet orientation, optionally with the keys of the keyboard housing facing the back side of a display of a display housing.

The orientation109may be a planar orientation where the angle θ is about 180 degrees such that a normal outward vector N1of the keyboard124of the keyboard housing120and a normal outward vector N2of the display141of the display housing140are oriented in approximately the same pointing directions.

Various computing systems such as laptop or notebook computing devices can be characterized at least in part by a footprint. For example, the device100ofFIG.1may be characterized at least in part by dimensions in x and y as to the keyboard housing120and/or as to the display housing140. As an example, a footprint can be an area that can be defined by a plane in the x and y directions of the Cartesian coordinate systems shown inFIG.1.

FIG.2AandFIG.2Bshow example scenarios201and202for a user220using the device100where the scenario201corresponds to poor ergonomics and the scenario202corresponds to improved ergonomics. As shown, the device100is supported on a surface210that is parallel to a floor surface211where a chair212is positioned on the floor surface211. As shown, the user220includes a head222, a spine224, arms with hands226and feet228. The user220is seated on the chair212with hands226at least in part supported on the surface210.

In the scenario201, the device100is supported by the housing120on the surface210and open such that the display housing140forms angles with the surface210, which include a back side angle ϕband a front side angle ϕfwhere the front side angle ϕfis greater than 90 degrees (e.g., approximately 91 degrees to 135 degrees) and, hence, the back side angle is less than 90 degrees (e.g., approximately 45 degrees to 89 degrees). As shown, the user220must curve her spine224to angle her head222to view the display of the display housing140.

In the scenario202, the display housing140is elevated through use of a stand180such that the back side angle ϕband the front side angle ϕfare approximately equal (e.g., equal to approximately 90 degrees+/−10 degrees). With the display housing140elevate to a greater height with respect to the surface210and at an approximately 90 degree angle, the user220can sit up more straight in the chair212such that her spine224can be in a more natural and stacked position with the head222approximately directly above the spine224. In such an example, the user220may utilize a foot rest213to rest her feet228, which may improve support of the user's body on the chair212.

As shown inFIG.2A, spine alignment problems may give rise to fatigue when using a device such as a notebook. As explained, and shown inFIG.2B, a stand may be available as an accessory to raise a display higher for improved posture such that the top leading edge of the display's active area is at eye level (e.g., for the anthropometric 50 percentile of adult-sized users).

However, having a notebook's display raised by an accessory stand can make the notebook's keyboard unusable because of the steep angle. For example, in the scenario202, the user220may have to use an accessory keyboard (e.g., a keyboard external to the device100).

When a user is in a workplace or other dedicated workstation, the user may have an accessory keyboard present along with the stand such that the user need not carry and transport the accessory keyboard from place to place, which may detract from the portability of the device.

Where a user's workstation has an accessory display, a user may position a notebook on a stand such that a display of the notebook is substantially even with a level of the accessory display. With multiple displays, a user may be more efficient and experience less fatigue. In some instances, a user may rely on workstation displays alone without use of a notebook's display but with use of the compute and network resources of the notebook (e.g., by plugging in one or more displays to the notebook, directly and/or through a docking station). Increased display area can allow a user to more effectively multitask, coordinate use of applications, etc.

For users that are often mobile and/or not working at dedicated workstations, the user may have to carry and transport an extra display. In some instances, the user may have to carry and transport an extra display, a stand and an accessory keyboard. Such extras can be detrimental to the user's mobility, and taxing as to what the user must remember to throw in to a travel bag, etc. For example, consider detriments to an individual that operates under a work practice referred to as hoteling (short-term provision of office space or workstations for employees or others). In various instances, a user may bring her notebook, an ergonomic stand and a tablet or second notebook in a backpack or a bag.

FIG.3shows an example of a display device300that includes a display panel340hinged to a support panel308that includes a first portion310hinged to a second portion320, where the display panel340includes a display341with a display surface344and that includes an opposing back surface346, where the support panel308is foldable over the display surface344and foldable over the back surface346, and where the first portion310is hingedly adjustable with respect to the second portion320for angled support of the display panel340.

In the example ofFIG.3, various features may be described with respect to one or more coordinate systems. For example, consider a Cartesian coordinate system xs, ysand zswhere a support surface can be in an xs,ys-plane where the display panel340may be positioned, for example, in an xs,zs-plane and then rotated back to rest on a portion of the support panel308or, for example, if a portion of a computing device is disposed between the support panel308and the display panel340, the display panel340may be rotated back to rest on the portion of the computing device.

In the example ofFIG.3, the display device300includes a first hinge360and a second hinge370where the first portion310and the second portion320are coupled via the first hinge360(see, e.g., a hinge axis ζ6) and where the display panel340and the support panel308are coupled via the second hinge370(see, e.g., a hinge axis ζ7). As shown, the first portion310includes opposing edges312and318, the second portion320includes opposing edges322and328and the display panel340includes opposing edges342and348where the edges318,322,328and348can be referred to as hinge edges where the edge322is a first hinge edge and the edge328is a second hinge edge of the second portion320. As shown, the first hinge360can join edges318and322and the second hinge370can join edges328and348.

As shown, a gap g1can be formed between the display panel340and the support panel308where the gap g1can have a length Lg, which is shown as being less than a length Ldpas defined by the edges342and348of the display panel340. Further, the display device300can include a tubular member330that can house a display connector350, for example, in a connector bay335defined at least in part by the tubular member330. As shown, the tubular member330can be defined using the Cartesian coordinate system xs, ysand zsand can have a cross-sectional shape (e.g., in a ys,zs-plane with a height h2) that may be substantially rectangular; noting that it may be circular, oval, etc. (e.g., with a shape to accommodate the display connector350). In the example ofFIG.3, a gap g2can be formed between the tubular member330and the display panel340. In such an example, the gap can be of a size (e.g., or of an adjustable size) such that the display panel340can fold over the tubular member330. For example, the tubular member330can be a spacer that spaces the display panel340and the support panel308when in a closed orientation (e.g., with the display panel340substantially parallel to the support panel308where the display surface344is facing the support panel308(e.g., to protect the display surface344, etc.). Such a closed orientation may be a storage orientation where, for example, a computing device may be disposed at least in part between the display panel340and the support panel308(e.g., consider a computing device such as a notebook, a tablet, etc.). In such an example, the display device300can be a computing device cover, which may help to protect the computing device while carrying it, transporting it, storing it, etc. In such an example, the second portion320may include a resilient portion that can allow it to be folded under the tubular member330. For example, material at the hinge370and/or along the second portion320near the hinge370may be resilient such that the display panel340can fold over the tubular member330and the support panel308can fold under the tubular member330where the tubular member330spaces the display panel340and the second portion320of the support panel308. As an example, a seam may exist that extends from the hinge370toward the tubular member330where the seam allows for increasing the gap g1and/or folding of the display panel340and the support panel308.

In the orientation shown inFIG.3, the gap g1can be sufficient (e.g., as is or adjustably) to receive at least a portion of a housing of a computing device. For example, consider inserting the keyboard housing120of the device100between the display panel340and the second portion320of the support panel308. In such an example, a lower edge of the display housing140may be substantially even with the edge342of the display panel340such that the display surface144of the display141of the display housing140and the display surface344of the display341of the display panel340are both visible to a user.

As an example, the display device300may be made of one or more elastomeric materials and/or include an elastically expandable mechanism. For example, the gap g1may be an adjustable gap where it can expand for receipt of a housing between the display panel340and the support panel308. In an expanded state, the gap g2may diminish in size (e.g., the display panel340may become closer to the tubular member330). As mentioned, a seam may be provided that can allow for adjustments where such a seam may be additional or alternative to utilization of one or more elastic mechanisms.

As an example, the hinge360and/or the hinge370can be a living hinge. As an example, a living hinge can be a relatively thin flexible hinge (e.g., flexure bearing, etc.). As an example, a living hinge may be made from a common material that is common to two panels. As an example, a living hinge may be thinned or cut to allow relatively rigid pieces to bend along a line or lines of the hinge. A living hinge may be configured for movement with low friction for low wear. As an example, a material can be elastomeric and provide for elastic deformation where one side may compress (compressive elastic deformation) while an opposing side experiences tension (e.g., tensile elastic deformation). As an example, an elastomeric material may be a polymeric material, a natural material, etc. As an example, a hinge can include one or more ribs, which may run longitudinally, for example, to demarcate one or more regions that are foldable, etc. As an example, a polymer can include one or more of polyethylene, polypropylene and other polymeric resin(s), which may exhibit acceptable fatigue resistance during cycles of folding.

As an example, a hinge can include fabric and may be referred to as a fabric hinge. As an example, one or more conductive fabrics may be utilized for electrical coupling between circuitry and a display connector, which, as mentioned, may provide for transmission of at least data and optionally power.

As an example, a hinge can be a mechanical hinge. For example, consider a piano type hinge, which may be a continuous hinge. As an example, a hinge can be a barrel hinge that includes a barrel, a pin and leafs. As an example, a mechanical hinge may be adjustable as to friction (e.g., a friction hinge) such that an angle can be maintained for a given amount of force. For example, consider a force (e.g., torque) that is to be applied to the first portion310about the axis ζ6to cause the first portion310to move. Such a force may be suitable for adjustment by hand while a lesser torque is a sufficient to maintain an angle between the first portion310and the second portion320in the orientation shown in the example ofFIG.3, with or without a notebook housing being received at least in part in the gap g1.

As to calculation of torque, consider an example for a notebook where an angle of a display housing is 45 degrees, the mass of the display housing is 2 lb (e.g., 0.9 kg), the length of the display housing is 10 inches (e.g., 25.4 cm) and the distance to the center of gravity (CoG) is 5 inches (e.g., 12.7 cm), assuming evenly distributed mass. In such an example, the torque exerted by the display housing on a hinge that couples the display housing to a keyboard housing at a 45 degree angle is: torque=(2 lb)(5 in)(cos 45 deg)=7.07 lb· in (e.g., approximately 0.8 N·m). As an example, the hinge360of the display device300may demand a torque of greater than approximately 2 lb· in (e.g., approximately 0.22 N·m) to cause rotation of one of the portions310and320with respect to the other one of the portions310and320.

In the example ofFIG.3, the hinge370can be an approximately 360 degree hinge such that the display surface344can be folded over the one or another side of the support panel308. As an example, the hinge360may be limited to a lesser range of movement, which may be unidirectional from a plane defined by the support panel308. As an example, the hinge360may have a range less than or equal to approximately 180 degrees.

In the example ofFIG.3, the display device300may be utilized as an auxiliary display (e.g., an accessory display, etc.). For example, the display connector350may be connected to a connector of a device (e.g., the device100, etc.) such that at least video signals can be received for rendering of information (e.g., text, graphics, images, etc.) to the display341of the display panel340. As shown, one or more conductors351can be operatively coupled to the display connector350for transmission of such signals. As an example, the display connector350may also provide for transmission of power. For example, consider a connector such as a USB-C connector that can carry video signals and power. In such an example, the display device300can be powered via another device (e.g., consider the device100ofFIG.1, etc.). As an example, the display device300may be utilized as a stand for another computing device or may be utilized separately while being connected to another computing device (e.g., directly and/or indirectly).

As to the support panel308, as explained, the portion310can be adjustable with respect to the portion320, for example, via the hinge360.FIG.3shows an example of a center of gravity, g, where the display device300can exert a force (e.g., F=mg) onto a surface such as the surface210inFIG.2AorFIG.2B. As shown, the portion310can form an angle ϕtwith respect to the portion320, which may be referred to as a tent angle. As an example, a portion of the tubular member330may include a shear resistant surface (e.g., rubberized, etc.) such that risk of sliding is reduced on a support surface. For example, a surface of the tubular member330may be an anti-slip surface such that the display device300can maintain stability in a desired position, with or without receipt of a device between the display panel340and the second portion320of the support panel308. As an example, the first portion310of the support panel308can include an anti-slip surface along at least a portion of the edge312for enhanced stability. As shown, the edge312can be at an end of the support panel308and parallel to the hinge edge318of the first portion310and the second portion320can include the opposing hinge edges322and328where the hinge edge322is paired with the hinge edge318. As mentioned, the hinge360can be a friction hinge that has a torque rating sufficient to maintain stability in a desired position, with or without receipt of a device between the display panel340and the second portion320of the support panel308(e.g., at least in part in the gap g1).

As shown in the example ofFIG.3, an angle of the second portion320with respect to a support surface can determine an approximate angle ϕdof the display surface344of the display panel340; noting that the gap g1may diminish in size in a direction from the edge328to the edge322. For example, at or near the edge322, the back side346of the display panel340may be in contact with the second portion320. In such an example, a space with a substantially triangular cross-section may be formed between the display panel340and the second portion320of the support panel308. As an example, the angle ϕdmay be adjustable where it can be adjustable within a range of approximately 90 degrees to approximately 135 degrees or more.

As an example, the display device300can be a stand and an auxiliary display for a computing device such as, for example, the device100ofFIG.1. As an example, the device100may be in the orientation101with the keyboard housing120received between the second portion320and the display panel340where the display141of the display housing140is exposed and viewable above the display panel340. Other arrangements may be provided as well. For example, consider the orientation105where the display141is viewable to one side and the display341is viewable to another side with the keyboard housing120disposed between the second portion320and the display panel340. As another example, consider the orientation107where the display housing140may overlay the display panel340with the keyboard housing120disposed between the second portion320and the display panel340.

The display device300may be carried and transported by a user along with a device such as, for example, the device100ofFIG.1(e.g., or a single housing tablet device, etc.) where a display of the display panel340can be utilized as a primary display or as an auxiliary display (e.g., a second display). Such an approach may be of lesser mass than a two notebook approach; noting that an accessory keyboard may be utilized such as, for example, a wired and/or wireless keyboard. As an example, the display device300can include wireless communication circuitry that can be suitable for pairing with wireless communication circuitry of a wireless keyboard. In such an example, the display connector350may provide for data such as keystroke data that can be received by a computing device that includes a connector that can mate with the display connector350. In such an example, keystroke data can flow in one direction (e.g., from the display device300to the computing device) and video data can flow in an opposite direction (e.g., from the computing device to the display device300). As an example, where the display device300includes wireless communication circuitry (e.g., one or more wireless interfaces), it may communicate with wireless communication circuitry of a computing device. In such an example, the display device300may be a bridge between an accessory and a computing device. For example, consider the display device300being an intermediate device that bridges an accessory keyboard to a computing device.

FIG.11,FIG.12,FIG.13,FIG.14,FIG.15andFIG.16show various examples of the display device300. InFIG.11,FIG.12andFIG.15, the display device300can be arranged with respect to a computing device such as, for example, the device100, where the keyboard housing120is exposed and available for use while the display surface344of the display341of the display panel340is exposed and visible above (FIG.11andFIG.12) or on an opposing side (FIG.15) of the display141of the display housing140. In such examples, an accessory keyboard may be optionally utilized or the keyboard124of the keyboard housing120may be utilized. As shown, where desktop, tabletop, countertop, etc., space is not available for an accessory keyboard, the keyboard124of the keyboard housing120can be utilized along with the display141and the display341of the display housing340.

As explained, elevating a display of a computing device using a stand (see, e.g.,FIG.2B) can help with ergonomics and user experience, for example, to reduce user fatigue. The display device300can provide an elevated display, which may be utilized for rendering of information for one or more applications. For example, a user may view the display141of the display housing140for a word processing application and view the display341of the display panel340for an email application where the display141is elevated above the display341(see, e.g.,FIG.5andFIG.6), or, for example, a user may view the display341of the display panel340for a word processing application and view the display141of the display housing140for an email application where the display341is elevated above the display141(see, e.g.,FIG.11andFIG.12).

As shown inFIG.3, the second portion320can be a front support portion of the support panel308that forms a stand along with the first portion310, which can be a back support portion of the support panel308. As an example, the tubular member330can be a cable garage (e.g., a connector bay where the connector includes a cable). For example, such a garage can store at least a portion of a cable that's used to connect the display341to a computing device. In such an example, the display connector350can be pulled out and plugged into the computing device (e.g., consider a HDMI connector, a DisplayPort (DP) connector, a USB-C connector, a Thunderbolt connector, a combination connector (e.g., Thunderbolt3and USB-C, etc.), etc.). As explained, a computing device can sit securely (e.g., with stability) against at least a portion of the display device300.

As an example, the display device300can be utilized as a cover for a computing device. For example, when utilized with a notebook, the notebook can fit between the support panel308and the display panel340where the display device300acts as a protective cover for travel. Such an arrangement can also ease access (e.g., using a single hand, etc.) when placing into or pulling out of bag or backpack.

As an example, a display device can include a pocket or other coupling feature(s) for an external keyboard. For example, consider one or more magnets that can provide magnetic attraction force to removably secure an accessory keyboard.

As explained, the support panel308can include the hinge360, which allows for adjustment of the first portion310with respect to the second portion320. As mentioned, such a hinge can be a friction hinge that provides support when holding and raising a computing device (e.g., notebook, etc.) off a surface.

As an example, the tubular member330can include one or more removable features. For example, consider a removable mouse that may be a foldable mouse (e.g., an origami mouse, etc.). In such an example, the mouse may be removably seated at an end that is an opposing end of the display connector350. As an example, the tubular member can include one or more human input devices (HIDs). For example, consider a touch-sensitive surface such as a touchpad and/or one or more rollers (e.g., roller wheels, track balls, etc.). In such examples, a user may touch and control a cursor, etc., using such one or more features of the tubular member330(e.g., consider thumb, index finger and/or middle finger control, navigation, etc.).

As an example, the display device300can include one or more rechargeable batteries, which may be part of one or more removable components. For example, consider a removable HID that includes a rechargeable battery. In such an example, where the display connector350provides for receipt of power, such power may be routed to one or more rechargeable batteries (e.g., via one or more interfaces), in a wired and/or wireless manner. As an example, consider a mouse that includes a rechargeable battery that can be charged using one or more interfaces of the display device300. In such an example, the mouse may plug into the tubular member300via an interface, which may be a wired interface (e.g., USB, etc.) for charging.

As an example, a HID may be a dual purpose device. For example, consider a mouse that includes memory such as 1 GB of memory or more that can be utilized for storage of information. In such an example, a user may remove the HID and utilize it as a mouse and/or a thumb drive. As an example, the tubular member330of the display device300may be outfitted with one or more features such that it provides a variety of features (e.g., single purpose features, multiple purpose features, etc.).

As explained, the display device300can be an ergonomic stand, provide an auxiliary display, be a protective cover, save space (e.g., in a backpack or bag), and include one or more accessories (e.g., an external keyboard, integrated storage pocket, an integrated mouse/thumb-drive, etc.).

As explained, the display341of the display device300may be oriented to be an elevated display (see, e.g.,FIG.4andFIG.5) or a lower display (see, e.g.,FIG.11andFIG.12). In such examples, a user may decide what to have rendered on the display341and, for example, a display of a computing device such as, for example, the display141of the device100. In such examples, a user may decide on utilizing an upper or elevated display for viewing information associated with primary tasks such that ergonomics are improved when compared to use of a notebook without a stand (see, e.g., the scenario201ofFIG.2Aversus the scenario202ofFIG.2B).

The display device300includes display circuitry where the display341can be an LED type of display or another type of display. As an example, the display341can be a touch-screen display, which may be a digitizer display, for example, operable using a stylus (e.g., consider a passive and/or an active stylus).

As explained, the display connector350can be a USB-C type of connector or another type of connector suitable for transmission of at least video data. As an example, one or more circuit boards can be included that are directly and/or indirectly electrically coupled to the display connector350and the display341. As an example, a hub or controller circuit board can be included along with a display circuitry board (e.g., a display driver board, etc.).

As an example, a display connector may be provided as a contact connector such as, for example, a pogo pin type of connector. In such an example, where a computing device includes a matching connector, the display device300may be utilized with a cable-based display connector. As an example, a display device can include one or more power interfaces and may include one or more rechargeable batteries (e.g., consider an integrated battery such as a 12 VDC battery, etc.). As an example, where provided with a power connector that may also be a display connector, a display device may operate using power from one or more sources.

As shown in the example ofFIG.3, the display device300can be a stand for the display341and/or for a computing device (see, e.g.,FIG.4). As explained, various orientations, arrangements, etc., may be provided via such a display device. As an example, the display device can be a stand, an auxiliary display and a cover.

FIG.4shows a front side perspective view of the display device300as a stand for the device100where the keyboard housing120of the device100is disposed at least in part between the second portion320of the support panel308and the display housing340. As shown, the display connector350is extended from the tubular member330via an opening335of the tubular member330such that a connector end351of the display connector350can be plugged into a port of the device100(e.g., USB-C, etc.). In the example ofFIG.4, an accessory keyboard190is shown as being positioned in front of the tubular member330. In the example ofFIG.4, the display housing140is operatively coupled to the keyboard housing120via the hinge assembly132, which may include one or more hinges, etc.

The arrangement ofFIG.4may be compared to the scenario202ofFIG.2Bwhere the display housing140is shown as being elevated and at an angle that is more ergonomic than in the scenario201ofFIG.2A.

FIG.5shows a back side perspective view of the arrangement ofFIG.4where the display device300is a stand for the device100. InFIG.5, a back side146of the display housing140can be seen along with a portion of a back side126of the keyboard housing120, which is exposed due to the first portion310of the support panel308being folded downward to form a tent like stand for the device100.

FIG.6shows a perspective view of a portion of the display device300in an assembly with the device100. As shown, the keyboard housing120includes a port121(e.g., a female connector, etc.) that can receive a portion of the connector end351of the display connector350, which includes a cable355. In the example ofFIG.6, the length of the cable355is in a range of approximately 10 cm to approximately 60 cm. As an example, a length of the cable355may be less than a length of the tubular member330. As an example, where a reel mechanism is utilized, a length of the cable355may be less than, equal to or greater than a length of the tubular member330. For example, consider a spring-biased reel that can take in and reel out a desired length of the cable355. As an example, the opening335of the tubular member330may be sized such that an interference fit (e.g., a press fit) is formed with the connector end351of the display connector350. For example, consider the tubular member330be formed of a resilient, elastically deformable material that can deform to receive the connector end351to removably secure the connector end351. As an example, the connector end351may be formed at least in part from a resilient, elastically deformable material.

FIG.7AandFIG.7Bshow perspective views of the display device300. In the view ofFIG.7A, the display surface344includes example renderings for ease in identifying the display surface344. As shown, the display device300can be arranged in a flat or planar orientation as inFIG.7Aand in a folded orientation as inFIG.7B, where the tubular member330is exposed, which is shown as optionally including a removable component390(e.g., a micro-mouse, a thumb drive, etc.).

FIG.8A,FIG.8BandFIG.8Cshow perspective views of the display device300along with the device100. As shown inFIG.8A, the display device300can cover the device100where the display surface344is exposed and where the tubular member330is exposed. As shown inFIG.8B, the display device300can cover the device100where the display surface344is not exposed but where the back side surface346of the display panel340is exposed. In the example ofFIG.8B, the tubular member330is disposed between the support panel308and the display panel340, for example, with ends visible from the sides. In such an example, the tubular member330may act as a spacer and/or a stop surface (e.g., a bumper, etc.) for the device100.

As shown inFIG.8C, a user may insert or remove the device100, for example, to cover the device100by the display device300as inFIG.8Bor for one or for use of the device100, optionally with the display device300as an auxiliary display and/or a stand. In the example ofFIG.8C, a surface324of the second portion320of the support panel308is visible. A user may slide the device100along the surface324until the device100contacts the tubular member330, which may be a support bumper. In such an example, when the device100is covered by the display device300as inFIG.8B, the tubular member330may provide mechanical shock protection (e.g., during carry, transport, contact with an object, etc.).

FIG.9shows a perspective view of the display device300and the device100where the back side surface346of the display panel340is visible, which may be positioned to be in contact with the keyboard124of the keyboard housing120of the device100.

FIG.10shows a perspective view of a portion of the display device300as including the removable component390, which may be a combination HID and memory device (e.g., thumb drive, etc.), as indicated by memory circuitry393(e.g., a memory chip with a memory controller, etc.). As an example, the removable component390can include an input mechanism392such as, for example, a wheel, a touch surface, a ball, a slider, etc. The removable component390may include a rechargeable battery394that can receive power via a plug399being received by a port339of the tubular member330. In the example ofFIG.10, the removable component390may be translatably removable and insertable for coupling with the tubular member330. As an example, a removable component may include a rechargeable battery that can be utilized to power another device. For example, consider utilization of the removable component390to provide power to a cell phone by plugging the plug399into a port of the cell phone to transmit power to the cell phone (e.g., consider a USB connection, a Thunderbolt connection, etc.). As an example, the removable component390may be a casting component that may receive video data and/or transmit video data. For example, the removable component390may be operable as a casting dongle. As an example, the removable component390may include a port such that it can be coupled to the connector350where upon connection, it may allow for at least wireless receipt of video data. In such an example, the removable component390and/or the display device300may include one or more rechargeable batteries that can power a display of the display panel340and/or circuitry of the removable component390.

FIG.11AandFIG.11Bshow perspective views of an example of the display device300with the device100(FIG.11A) and with a tablet device1100(FIG.11B). As shown, the display surface344of the display device300can be elevated above the display144or a display1144where the display device300. In such examples, the display device300may be oriented in a zig-zag manner, for example, defined by three planes, a plane of the first portion310, a plane of the second portion320and a plane of the display panel340. As shown, the plane of the display panel340may be substantially orthogonal to a plane of a support surface on which the keyboard housing120and the edge312of the first portion310are supported. Such an arrangement can be compared to the scenario202ofFIG.2B, which, in the examples ofFIG.11AandFIG.11B, provides for ergonomic viewing of the display surface344. In the example ofFIG.11A, for the device100, the keyboard124is exposed such that it may be utilized with both displays141and341. For example, a user may type using the keyboard124where commands, instructions, etc., can instruct one or more processors to render information to the display141and/or the display341.

FIG.12shows a back side perspective view of the example ofFIG.11A. As shown, the hinge360can be a gusset type of hinge that may be made of planar material with cuts that separate a portion or portions of the planar material from the first portion310and the second portion320of the support panel308. As shown, the hinge360can extend outwardly such that resistance exists to further movement of the portions310and320with respect to each other. For example, an angle ϕhis shown along with the tent angle ϕt. In such an example, the hinge360can generate stiffness that resists further decrease in the angle ϕh, which can define the angle ϕt. The hinge360may be a type of living hinge in that the creases illustrated are formed via thinning of a material. For example, the support panel308can be made of a polymeric or other material where a juncture is thinned to define the first portion310and the second portion320and where cuts are made such that a portion of the material juts outwardly as in forming the angle ϕh. In such an example, mechanical resistance can exist within the jutted out portion (e.g., two panel portions) such that the angle ϕhis stabilized for support of the display panel340with contact between the second portion320and the back side surface146of the display housing140of the device100.

FIG.13AandFIG.13Bshow perspective views of examples of the display device300. As shown, the display device300can include a contact interface397and one or more magnets398-1and398-2. As shown inFIG.13B, the display device300can include the tubular member330and the display connector350. As an example, the display device300may attach to a computing device via the one or more magnets398-1and398-2such that a contact promoting force is applied to the contact interface397, which may be, for example, a spring-biased contact interface (e.g., pogo pins, etc.). In such an example, transfer of at least video may occur via the contact interface397where the computing device includes an appropriate mating, matching interface, along with ferromagnetic material (e.g., optionally one or more magnets) that can be attracted to the one or more magnets398-1and398-2.

FIG.14shows various perspective views that illustrate example methods of arranging an example of the display device300with respect to the device100. As shown, the display device300can be a cover for the device100that can be opened to expose the device100where the device100and the display device300can be positioned such that the magnets398-1and398-2of the display device300can attract to material198-1and198-2of the device100where such attraction can cause contact between the contact interface197and a contact interface147of the display housing140of the device100.

FIG.15shows a perspective view of an example of the display device300along with the device100. As shown, the display panel340can be rotated about the hinge370to form a tent with the support panel308. In such an example, the first portion310and the second portion320of the support panel308are in a common plane, which is substantially parallel to a plane of the display housing140of the device100. In such an example, one person may view the display341and another person may view the display341while being able to utilize features of the keyboard housing120(e.g., the keyboard124, the touchpad123, etc.). As an example, one or both of the displays141and341may be touch-screen displays. As an example, the display panel340can include one or more sensors that can detect orientation of the display panel340, for example, with respect to gravity. In such an example, circuitry of the display device300and/or the device100can be instructed to properly render information to the display341. For example, when the display341is facing the same side as the display141, rendering to both displays may be in a common orientation; whereas, when the display341is flipped over as shown inFIG.15, circuitry may be instructed to render information in a different orientation (e.g., where bottom is now the top and the top is now the bottom, such as a 180 degree rotate).

FIG.16shows various perspective views of an example of the display device300that illustrate methods of arranging the display device300with respect to the device100. As shown, the display device300can be utilized as a cover for the device100.

As shown in the examples ofFIG.12,FIG.13A,FIG.13B, andFIG.14, the device100can be attached to the second portion320of the support panel308. In such an example, the support panel308can include a gusset type of feature and, for example, one or more magnets. In the example ofFIG.11andFIG.12, the keyboard124of the device100and its touchpad123are exposed as they are not covered by the display device300nor angled in a manner that would prevent use thereof. In such an example, a user may operate the display device300as coupled to the device100without using an accessory keyboard (e.g., or accessor mouse, etc.).

As explained, a display device may or may not include a display connector (e.g., a video connector, etc.) that is on a cable. For example, a contact connector may be utilized where a computing device includes a matching contact connector. As an example, a display device may include a contact connector, a cable-based connector or a contact connector and cable-based connector.

As explained, the hinge360may be a living type of hinge. For example, consider a die-cut like fold creating an integrated living hinge for gusset support.

As explained, a display device can provide for a tent mode or tent orientation with a notebook computer, which may be suitable for collaboration between individuals. For example, consider one user presenting with the notebook's display pointed at her and someone on the opposite side viewing the presentation from the display device's display.

As explained, a display device can be an ergonomic stand, an auxiliary display, a travel protection cover as a space saving device for easy access from a backpack or bag, and, for example, configurable in a tent mode for collaboration where a notebook's keyboard and touchpad are accessible.

As an example, a display device can include a display panel hinged to a support panel that includes a first portion hinged to a second portion, where the display panel includes a display surface and a back surface, where the support panel is foldable over the display surface and foldable over the back surface, and where the first portion is hingedly adjustable with respect to the second portion for angled support of the display panel. In such an example, the display device can include a display connector operatively coupled to display circuitry of the display panel. For example, consider a display connector that includes a cable where, for example, the display device can include a display connector bay for storage of the display connector. In such an example, the display connector may be stored when not used and deployable for use, with return to the display connector bay when use is finished.

As an example, a display device can include a tubular member coupled to a hinge end of a support panel. In such an example, the tubular member can include at least one storage bay. For example, consider at least one storage bay that is a memory device bay. As an example, for a support panel folded over a display surface of a display panel of a display device, a tubular member of the display device can space the support panel from the display surface to form a computing device recess between the support panel and the display panel (e.g., consider a tablet computing device recess or a laptop computing device recess that can receive a laptop computing device in a closed clamshell orientation) where, for example, the tubular member can include a computing device stop surface that can contact a computing device. In such an example, the display device may be arranged in another configuration such that the display panel folds over at least a portion of the support panel with the tubular member exposed where a gap exists between surfaces of the display panel and the support panel where the gap can be a housing recess gap for receipt of at least a portion of a housing of a computing device such as, for example, a keyboard housing of a laptop computing device such that a display housing of the laptop computing device is exposed and positioned above the display panel of the display device. As explained, where, the support panel is folded over the back surface of the display panel, the tubular member can be exposed. In such an example, where the tubular member includes one or more bays, the one or more bays may be more readily accessible.

As an example, a display device can include a first portion and a second portion of a support panel where the second portion includes at least one magnet. In such an example, contact force for mating of an electrical contact interface with an electrical contact interface of a computing device can be generated at least in part by magnetic attraction forces of the at least one magnet. In such an example, the electrical contact interface can include at least one spring. For example, consider one or more springs of one or more pogo pins.

As an example, an assembly can include a computing device that includes a housing and a display; and a computing device stand that includes a display panel that includes an auxiliary display. In such an example, the computing device stand can include a display connector operatively coupled to the auxiliary display. For example, consider a display connector that includes a cable or a cableless electrical contact connector (see, e.g.,FIG.13Bwhere a cable connector and a cableless electrical contact connector (the contact interface397) are shown). In such examples, the auxiliary display may be connected via electrical contact via one or more mechanisms to receive at least video data from the computing device. As explained, a display device, which may be a computing device stand with a display, may include wired and/or wireless circuitry to receive at least video data. As an example, a wired interface can include a cableless electrical contact connector such as, for example, a pogo pin connector, etc.; whereas, a wireless interface can be operable to receive and/or transmit data without physical contact between two devices. As an example, a computing device stand can include a display panel and a support panel, where the display panel is hinged to the support panel, and where the support panel includes a first portion hinged to a second portion. In such an example, a computing device suitable for use with the computing device stand may be a tablet computing device (see, e.g.,FIG.11B) or may be a laptop computing device (see, e.g.,FIG.4,FIG.5,FIG.6,FIG.11A,FIG.12, andFIG.15).

The term “circuit” or “circuitry” is used in the summary, description, and/or claims. As is well known in the art, the term “circuitry” includes all levels of available integration (e.g., from discrete logic circuits to the highest level of circuit integration such as VLSI, and includes programmable logic components programmed to perform the functions of an embodiment as well as general-purpose or special-purpose processors programmed with instructions to perform those functions) that includes at least one physical component such as at least one piece of hardware. A processor can be circuitry. Memory can be circuitry. Circuitry may be processor-based, processor accessible, operatively coupled to a processor, etc. Circuitry may optionally rely on one or more computer-readable media that includes computer-executable instructions. As described herein, a computer-readable medium may be a storage device (e.g., a memory chip, a memory card, a storage disk, etc.) and referred to as a computer-readable storage medium, which is non-transitory and not a signal or a carrier wave.

While various examples of circuits or circuitry have been discussed,FIG.17depicts a block diagram of an illustrative computer system1700. The system1700may be a computer system, such as one of the ThinkCentre® or ThinkPad® series of personal computers sold by Lenovo (US) Inc. of Morrisville, N.C., or a workstation computer system, such as the ThinkStation®, which are sold by Lenovo (US) Inc. of Morrisville, N.C.; however, as apparent from the description herein, a system or other machine may include other features or only some of the features of the system1700. As an example, one or more of the device100, the display device300, the device1100, etc., may include at least some of the features of the system1700.

As shown inFIG.17, the system1700includes a so-called chipset1710. A chipset refers to a group of integrated circuits, or chips, that are designed (e.g., configured) to work together. Chipsets are usually marketed as a single product (e.g., consider chipsets marketed under the brands INTEL®, AMD®, etc.).

In the example ofFIG.17, the chipset1710has a particular architecture, which may vary to some extent depending on brand or manufacturer. The architecture of the chipset1710includes a core and memory control group1720and an I/O controller hub1750that exchange information (e.g., data, signals, commands, etc.) via, for example, a direct management interface or direct media interface (DMI)1742or a link controller1744. In the example ofFIG.17, the DMI1742is a chip-to-chip interface (sometimes referred to as being a link between a “northbridge” and a “southbridge”).

The core and memory control group1720include one or more processors1722(e.g., single core or multi-core) and a memory controller hub1726that exchange information via a front side bus (FSB)1724. As described herein, various components of the core and memory control group1720may be integrated onto a single processor die, for example, to make a chip that supplants the conventional “northbridge” style architecture.

The memory controller hub1726interfaces with memory1740. For example, the memory controller hub1726may provide support for DDR SDRAM memory (e.g., DDR, DDR2, DDR3, etc.). In general, the memory1740is a type of random-access memory (RAM). It is often referred to as “system memory”.

The memory controller hub1726further includes a low-voltage differential signaling interface (LVDS)1732. The LVDS1732may be a so-called LVDS Display Interface (LDI) for support of a display device1792(e.g., a CRT, a flat panel, a projector, etc.). A block1738includes some examples of technologies that may be supported via the LVDS interface1732(e.g., serial digital video, HDMI/DVI, display port). The memory controller hub1726also includes one or more PCI-express interfaces (PCI-E)1734, for example, for support of discrete graphics1736. Discrete graphics using a PCI-E interface has become an alternative approach to an accelerated graphics port (AGP). For example, the memory controller hub1726may include a 16-lane (×16) PCI-E port for an external PCI-E-based graphics card. A system may include AGP or PCI-E for support of graphics. As described herein, a display may be a sensor display (e.g., configured for receipt of input using a stylus, a finger, etc.). As described herein, a sensor display may rely on resistive sensing, optical sensing, or other type of sensing.

The I/O hub controller1750includes a variety of interfaces. The example ofFIG.17includes a SATA interface1751, one or more PCI-E interfaces1752(optionally one or more legacy PCI interfaces), one or more USB interfaces1753, a LAN interface1754(more generally a network interface), a general purpose I/O interface (GPIO)1755, a low-pin count (LPC) interface1770, a power management interface1761, a clock generator interface1762, an audio interface1763(e.g., for speakers1794), a total cost of operation (TCO) interface1764, a system management bus interface (e.g., a multi-master serial computer bus interface)1765, and a serial peripheral flash memory/controller interface (SPI Flash)1766, which, in the example ofFIG.17, includes BIOS1768and boot code1790. With respect to network connections, the I/O hub controller1750may include integrated gigabit Ethernet controller lines multiplexed with a PCI-E interface port. Other network features may operate independent of a PCI-E interface.

The interfaces of the I/O hub controller1750provide for communication with various devices, networks, etc. For example, the SATA interface1751provides for reading, writing or reading and writing information on one or more drives1780such as HDDs, SDDs or a combination thereof. The I/O hub controller1750may also include an advanced host controller interface (AHCI) to support one or more drives1780. The PCI-E interface1752allows for wireless connections1782to devices, networks, etc. The USB interface1753provides for input devices1784such as keyboards (KB), one or more optical sensors, mice and various other devices (e.g., microphones, cameras, phones, storage, media players, etc.). On or more other types of sensors may optionally rely on the USB interface1753or another interface (e.g., I2C, etc.). As to microphones, the system1700ofFIG.17may include hardware (e.g., audio card) appropriately configured for receipt of sound (e.g., user voice, ambient sound, etc.).

In the example ofFIG.17, the LPC interface1770provides for use of one or more ASICs1771, a trusted platform module (TPM)1772, a super I/O1773, a firmware hub1774, BIOS support1775as well as various types of memory1776such as ROM1777, Flash1778, and non-volatile RAM (NVRAM)1779. With respect to the TPM1772, this module may be in the form of a chip that can be used to authenticate software and hardware devices. For example, a TPM may be capable of performing platform authentication and may be used to verify that a system seeking access is the expected system.

The system1700, upon power on, may be configured to execute boot code1790for the BIOS1768, as stored within the SPI Flash1766, and thereafter processes data under the control of one or more operating systems and application software (e.g., stored in system memory1740). An operating system may be stored in any of a variety of locations and accessed, for example, according to instructions of the BIOS1768. Again, as described herein, a satellite, a base, a server or other machine may include fewer or more features than shown in the system1700ofFIG.17. Further, the system1700ofFIG.17is shown as optionally include cell phone circuitry1795, which may include GSM, CDMA, etc., types of circuitry configured for coordinated operation with one or more of the other features of the system1700. Also shown inFIG.17is battery circuitry1797, which may provide one or more battery, power, etc., associated features (e.g., optionally to instruct one or more other components of the system1700). As an example, a SMBus may be operable via a LPC (see, e.g., the LPC interface1770), via an I2C interface (see, e.g., the SM/I2C interface1765), etc.

Although examples of methods, devices, systems, etc., have been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as examples of forms of implementing the claimed methods, devices, systems, etc.
