DETAILED DESCRIPTION

[0009] In the following description and figures, some example implementations of apparatus with a display panel, display systems, computer- readable mediums with instructions of operation of a light source, and/or methods of operation of a light source are described. An apparatus with a display panel may be a display device and/or include a display device. As used herein, a “display system” includes circuitry to operate a display device. An example apparatus may be an all- in-one compute device with a general-purpose processor and an integrated display device. In examples described herein, a “display device” is a device to present content visually. Example display devices may include a screen such as a liquid crystal display (LCD) panel, an organic light-emitting diode (OLED) panel, a micro light emitting diode (pLED), or other display technology. In some examples, a display device may also include circuitry to operate the screen, such as a monitor scaler.

[0010] A display device may present (e.g., display) an image on a panel using light by causing a color to display for every pixel on the panel. Data used to determine the color for each pixel may be determined by source image data. The source image data may include color data according to a color space such as red, green, and blue (RGB) channel data. For liquid crystal display (LCD) panels, color characteristic information may include spectral output of the backlight and the tone of the color filters applied on the top of the grayscale liquid crystals. The display memory may be used to store multiple color calibration profiles that correspond to a plurality of luminosity ranges or “display modes,” such as standard RGB (sRGB), high dynamic range (HDR), standard dynamic range (SDR), etc. These may be referred to as color presets when selected on the display device.

[0011] A user may desire to adjust the lighting of the area where the user is located while operating the display device. For example, the user may want room lighting to be dim while watching a movie on the display device and bright room lighting when using a word processor as displayed on the display device. In some examples, a user may desire that the environmental lighting to match the color presets of the display device (e.g., reproduce a similar range of colors as displayed on the display panel). Indeed, users may want adjustable lighting options when changing between modes of operation.

[0012] Various examples described below relate to a display device with adjustable lighting (in addition to the display panel) that is operable in multiple modes and is able to be oriented into multiple positions. For example, an external light source may be moveable from one area of the housing of the display device, such as the back of the display device, to a second area of the housing of the display device, such as the front of the display. The light sources may also be adjustable, such as between offering white LED operation and color LED operation. By providing a light source on a rotatable arm, where the light source may be stowed into a recess of the housing, the light source may be adjustable into multiple orientations based on the desired operation of a user. [0013] FIGS. 1 and 2 are block diagrams depicting example display systems 100 and 200. Referring to FIG. 1 , the example display system 100 of FIG. 1 generally includes a display panel 102, a housing 106, an arm 110, and a light source 112. In general, the display panel 102 is coupled to the housing 106, a light source 112 is coupled to an arm 110, and the arm 110 is rotatably coupled to the housing 106. In this manner, the arm 110 can rotate the light source 112 to multiple positions with respect to the housing 106, including into a recess 108 of the housing 106.

[0014] The housing 106 may contain electronics such as a video processor for operating the display panel 102. The housing 106 includes a surface having walls that form a recess 108. The recess 108 may be sufficiently large to receive the light source 112 into the recess based on rotation of the arm 110.

[0015] The arm 110 is rotationally coupled to the housing 106, such as via a hinge located adjacent the recess 108. In some examples, the light source 112 is fixedly coupled to the arm 110. In other examples, the light source 112 is rotationally coupled to the arm 110.

[0016] The arm 110 is able to rotate the light source 112 to a plurality of position. For example, the arm 110 may be able to rotate the light source 112 from a first position located within the recess 108 of the housing 106 to a second position located outside the recess 108 of the housing 106. For example, the arm 112 may rotate the light source from being directed from the back of the housing 106 to in front of the display panel 102. The arm 110 may rotate about 360 degrees to a desired location for the light source 112. In other example ranges of rotation of the arm 110 include a range of about 270 degrees, a range of about 180 degrees, and a range of about 90 degrees.

[0017] The light source 112 may be any circuitry or device capable of emitting light. The light source 112 is adjustable and may be adjustable in position and electrical operation. For example, the light source 112 may be adjusted to generate light of a first color range in a first position and adjusted to generate light of a second color range in a second position. For another example, the light source 112 may be turned on in a first position and turned off in a second position. In some examples, the light source 112 may be powered on while another light source is powered off in the same position. In this manner, a selection of light sources may be operated based on the position of the light source 112 and/or orientation of the arm 110. The light source 112 may be oriented in a direction substantially opposite of the direction of light emitted from the display panel 102 when in a first position, and the light source 112 may be oriented in a direction substantially parallel to light emitted from the display panel 102 when in a second position.

[0018] In some examples, functionalities described herein in relation to any of FIGS. 1-2 may be provided in combination with functionalities described herein in relation to any of FIGS. 3-12.

[0019] Referring to FIG. 2, the example display system 200 of FIG. 2 generally includes a display panel 202, a housing 206, an arm 210, hinges 228 and 230, light sources 212 and 214, a controller 220, and a cable 226 to couple the controller 220 to the light sources 212 and 214. In general, the controller 220 controls operation of the light sources 212 and 214, the light sources 212 and 214 are coupled to the arm 210, and the arm 210 is rotatably coupled to the housing 106. In this manner, the arm 210 can rotate about the hinge 228 to move the light sources 212 and 214 to multiple positions with respect to the housing 206, including into a recess 208 of the housing 206 or towards the bezel 204 where the display panel 202 is located.

[0020] The controller 220 is circuitry including a processor resource and a memory resource with a control program stored thereon. In some examples, a controller 220 may be a video processor of a display device, such as a monitor scaler or a graphics processing unit. The controller 220 causes the light sources 212 and 214 to operate based on execution of the control program by the processor resource. In some examples, the controller 220 causes the arm 210 to rotate about the hinge 228 via operation of the motor 224.

[0021] The controller 220 may receive signals generated by the sensor 222. The sensor 222 may be any appropriate sensor to generate a signal based on the orientation of the arm 210, such as a light sensor, an electromagnetic sensor, etc. The sensor 222 may generate a signal based on position of the arm 210 and/or rotation of the hinge 228. The controller 220 may utilize data received from the sensor 222 (e.g., a signal corresponding to the rotation of the hinge 228 and/or the position of the arm 210) to determine which mode to place the light source 212 and/or 214. For example, the sensor 222 may be attached to a pin protruding towards a gear of the hinge 228 with indentations to indicate when the arm 210 reaches a position in front of the display panel 202 and when the arm 210 reaches a position to place the bar 216 into the recess 208 of the housing 206. [0022] The bar 216 represents a container or other support to which the light sources are attached. For example, the light sources 212 and 214 may be located in the bar 216 along with a number of other light sources, and the bar 216 may be locatable in the recess 208 of the housing 206 when the arm 210 is in a first position corresponding to a first position of the light sources 212 and 214 oriented away from the back of the housing 206 opposite the display panel 202. In this manner, the arm 210 may rotate the light sources 212 and 214 in parallel by moving the position of the bar 216. In other examples, the arm 210 may rotate the light sources into positions independently of each other and/or independently of rotation of the arm 210.

[0023] The controller 220 electrically communicates with the light sources 212 and 214 via the cable 226 (e.g., to provide power and/or data). The cable 226 may electrically connect the light sources 212 and 214 and the display panel 202 via a hinge 228 at which the arm 210 is rotatably connected to the housing 206, and the controller 210 may operate the light sources 212 and 214 and the display panel 202 to operate in the same modes or different modes. The cable 226 may generally represents one or a combination of a cable, wireless connection, an infrared link, a radio frequency link, or any other connectors of systems that provide electronic communication.

[0024] In some examples, the controller 220 causes the light sources 212 and 214 to operate in a light mode based on a light profile corresponding to an orientation of the arm 210. As used herein, a “light mode” is an attribute or a combination of attributes at which a light source is to operate. An example of an attribute of light mode is a light source being turned off or on. As used herein, a “light profile” is a data structure to store an attribute of operation of a light source. For example, the light profile may include data representing a set of light sources to be operated, the amount of light produced the by the set of light sources, and the color of light produced by the light sources. As used herein, a “color profile” is a data structure to store an attribute of the color of light to be produced by at least one light source. A light profile may include a color profile, such as a color profile corresponding to a set or range of colors corresponding to a light mode. In some examples, the controller 210 causes the light sources 212 and 214 to change operational mode based on orientation of the light source with respect with respect to the arm and orientation of the arm with respect to the housing, such as in an example implementation where the light sources 212 and 214 are coupled to the arm 210 via the rotatable hinge 230.

[0025] The motor 224 may assist movement of the arm 210 among rotational positions. In some examples, the controller 210 operates the motor 224 in response to a user selection of a light mode, such as causing the motor to rotate the arm automatically when a selection of a color preset for the light sources 212 and 214 from a user interface of a display manager application or an on-screen display menu is made. In some examples, a signal from the motor may designate when to change the light mode (e.g., select a different light profile to operate the light sources 212 and 214).

[0026] FIGS. 3 and 4 are flow diagrams depicting example methods 300 and 400 of operation of a light source based on orientation. The methods 300 and 400 may be implemented by circuitry, such as the controller 220 of FIG. 2. Referring to FIG. 3, example method 300 of operation of a light source based on orientation may generally comprise comparing orientation datum to a position threshold and causing a plurality of light sources to operate based on the orientation datum.

[0027] At block 302, an orientation datum corresponding to an arm is compared to a position threshold. The orientation datum of the arm may be based on the rotatable position of the arm with respect to a display device, and the position threshold may represent an angle of rotation of the arm corresponding to the recess of the housing of the display device. The light sources may be operated based on the angle of the arm with respect to the display device, for example, by a controller based on sensor data corresponding to a sensed position of the arm. The orientation datum may be retrieved from or sent by a sensor associated with the arm to which the light sources are coupled. For example, if a sensor detects movement of the arm 90 degrees from a recessed starting position, a controller may determine to change light modes and retrieve a light profile corresponding to operation of the light sources in the second mode.

[0028] At block 304, a plurality of light sources coupled to the arm are operated in a first mode when the orientation datum is less than the position threshold. At block 306, the plurality of light sources operate in a second mode when the orientation datum is more than the position threshold. Such operations at block 304 and 306 may be caused by a controller, such as a programmed video processor. The second mode may cause a different number of lights to operate and/or cause the lights to operate under different attributes than the first mode. In this manner, the light sources may operate in different modes based on comparison to a position threshold to indicate which mode the light sources are to operate in. As discussed with respect to FIG. 4, the light sources may operate based on a light profile associated with the operational mode of the lights, which light profile may be selected by a controller based on the orientation of the arm, for example.

[0029] Referring to FIG. 4, example method 400 of operation of a light source based on orientation may generally comprise comparing orientation datum to a position threshold, retrieving a color profile corresponding to a light mode, and operate a plurality of light sources based on the orientation datum.

[0030] At block 402, an orientation datum corresponding to an arm is compared to a position threshold the same as performed at block 302 of FIG. 3. At block 404, a color profile corresponding to a first mode or a second mode is retrieved based on the comparison of the orientation datum to the position threshold performed at block 402. Retrieval of a color profile may include modifying a color profile and/or generating a color profile based on a user-defined customization.

Retrieval of a color profile may also include generating a profile request from a host device coupled to a display device in response to a change in position of the plurality of light sources. Such retrieval, modification, and/or request generation may be performed by a controller, such as a video processor of a display device. Light profiles and/or color profiles may be stored on the display device, a host device, an externally attached storage device, a server, or distributed across such devices. [0031] At block 406, the plurality of light sources is caused, such as via a processor resource, to operate according to the color profile retrieved at block 404 when exterior lighting is selected to be enabled (e.g., selected to operate the light sources on the bar 616 via an on-screen display menu or display manager application). The color profile may be based on a light mode as determined by a controller and designated by a combination of an angle of rotation of the arm with respect to display, and in some examples, also the angle of rotation of the plurality of lights sources with respect to the arm. For example, the arm may be position at a 45 degree angle with respect to the display panel and the light sources may operate in a first mode with a first color profile (e.g., RGB LED light) when the light sources emit light substantially parallel to the display panel and operate in a second mode with a second color profile (e.g., white light) when the light sources emit light substantially perpendicular to the display panel. In some examples, the plurality of light sources is caused, by a processor resource, to change operation in response to operation of a motor coupled to the arm. In that example, the motor may cause the arm to rotate from a first orientation where the plurality of light sources is located within the recess on a back side of the display device to a second orientation where the plurality of light sources is located on a front side of the display device, and the light sources may be cause to operate in different modes corresponding to the different orientations of the arm and/or orientations of the light sources.

[0032] Although the flow diagrams of FIGS. 3-4 illustrate specific orders of execution, the execution order may differ from that which is illustrated. For example, the execution order of the blocks may be scrambled relative to the order shown. Also, the blocks shown in succession may be executed concurrently or with partial concurrence. All such variations are within the scope of the present description. [0033] FIG. 5 is a block diagram depicting an example controller 500. FIG. 5 depicts the example controller 520 may comprise a memory resource 550 operatively coupled to a processor resource 542. The memory resource 550 may contain a set of instructions that are executable by the processor resource 542. The set of instructions are operable to cause the processor resource 542 to perform operations (e.g., operations of the systems 100 and 200 of FIGS. 1-2 and/or the methods 300 and 400 of FIGS. 3-4) when the set of instructions are executed by the processor resource 542. The set of instructions stored on the memory resource 550 may be represented as an arm module 502, a mode module 504, and a light module 506. The arm module 502 represents program instructions that when executed cause operation of the arm 110 of FIG. 1 . For example, the arm module 502 may represent program instructions that when executed cause a motor to control rotation of the arm into a position within the recess of the housing or outside the recess. For another example, the arm module 502 may represent program instructions that when executed cause a processor resource to retrieve data from a sensor and compare the data to a position threshold. The mode module 502 represents program instructions that when executed cause a processor resources to select a mode corresponding to the orientation of the arm. For example, the mode module 504 may represent program instruction that when executed cause a processor resource to perform retrieval of a light profile corresponding to a mode determined based on the orientation of the arm. The light module 506 represents program instructions that when executed cause operation of the light source 112 of FIG. 1 . For example, the light module 506 may represent program instructions that when executed cause a processor resource to send electrical signals to the light sources in accordance with the light profile to indicate attributes of operation of the light sources (e.g., on or off, light color, brightness, etc.). The processor resource 542 may carry out a set of instructions to execute the modules 502, 504, 506, and/or any other appropriate operations among and/or associated with the modules of the system or device in which the controller 520 is integrated. For example, the processor resource 542 may carry out a set of instructions to perform operations discussed with respect to the method 300 of FIG. 3 and/or the method 400 of FIG. 4.

[0034] Although these particular modules and various other modules are illustrated and discussed in relation to FIG. 5 and other example implementations, other combinations or sub-combinations of modules may be included within other implementations. Said differently, although the modules illustrated in FIG. 5 and discussed in other example implementations perform specific functionalities in the examples discussed herein, these and other functionalities may be accomplished, implemented, or realized at different modules or at combinations of modules. For example, two or more modules illustrated and/or discussed as separate may be combined into a module that performs the functionalities discussed in relation to the two modules. As another example, functionalities performed at one module as discussed in relation to these examples may be performed at a different module or different modules.

[0035] A processor resource is any appropriate circuitry capable of processing (e.g., computing) instructions, such as one or multiple processing elements capable of retrieving instructions from a memory resource and executing those instructions. For example, the processor resource 542 may be a central processing unit (CPU) that enables operation of a light source by fetching, decoding, and executing modules 502, 504, and 506. Example processor resources include at least one CPU, a semiconductor-based microprocessor, a programmable logic device (PLD), and the like. Example PLDs include an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a programmable array logic (PAL), a complex programmable logic device (CPLD), and an erasable programmable logic device (EPLD). A processor resource may include multiple processing elements that are integrated in a single device or distributed across devices. A processor resource may process the instructions serially, concurrently, or in partial concurrence.

[0036] A memory resource represents any non-transitory medium or combination of non-transitory media able to electronically store data. For example, the medium may be a storage medium, which is distinct from a transitory transmission medium, such as a signal. The medium may be machine-readable, such as computer-readable. The medium may be an electronic, magnetic, optical, or other physical storage device that is capable of containing (i.e. , storing) executable instructions. A memory resource may be said to store program instructions that when executed by a processor resource cause the processor resource to implement functionality of the apparatus. The instructions residing on a memory resource may comprise any set of instructions to be executed directly (such as machine code) or indirectly (such as a script) by a processor resource. A memory resource may be integrated in the same device as a processor resource or it may be separate but accessible to that device and the processor resource. A memory resource may be distributed across components and/or devices.

[0037] A memory resource may be a non-volatile memory resource such as read-only memory (ROM), a volatile memory resource such as random-access memory (RAM), a storage device, or a combination thereof. Example forms of a memory resource include static RAM (SRAM), dynamic RAM (DRAM), electrically erasable programmable ROM (EEPROM), flash memory, or the like. A memory resource may include integrated memory such as a hard drive (HD), a solid-state drive (SSD), or an optical drive.

[0038] FIG. 6 depicts an example display device 600. The display device 600 depicts a bezel 604 around a display panel 602 supported by a stand 660. An arm 610 extends above the display panel 602 and bezel 604. A bar 616 is coupled to an end of the arm 610, and light sources 612 and 614 are attached to the bar 616. The light sources 612 and 614 may be operable to illuminate an object in front of the display panel 602, for example.

[0039] FIG. 7 is an isometric view of the example display device 600 of FIG. 6 with a light source 614 in a position outside of a recess 608 of the housing 606 of the display device 600. The bar 616 is rotatably connected to the arm 610 via the hinge 630, and the arm 610 is rotatably connected to the housing 606 (e.g., within the recess 608) via hinge 628. In the positions shown in FIG. 7, the light sources 612 and 614 are depicted in a front position on the illumination side of the display panel 602.

[0040] FIG. 8 is an isometric view of the example display device of FIG. 6 with a light source 614 in a position inside a recess 608 of the housing 606 of the display device 600. The recess 608 is large enough to receive the entirety of the length of the bar 616 and the arm 610 (as well as hinges 628 and 630). The wall 609 may be set back sufficiently to allow for depth to encompass the entirety of the width of the bar 616 and the arm 610. In the positions shown in FIG. 8, the light sources 612 and 614 are depicted in a back position on the side where electronics of the display device 600 are stored, also known as the bucket, and where the display panel 602 does not provide illumination. In other examples, the bar 616 may be a different length, such as the length of the display panel, and a recess defined by the housing may match or otherwise accommodate the size of the bar 616.

[0041] A surface of the bar, such as a cover for the light sources 612 and 614, may align flush with the back wall(s) of the housing 606 that defines the recess 608 when the arm 610 is in the recess position (e.g., where the arm is located towards and inside the recess). The arm 610 may be moveable into a plurality of positions such as the positions depicted in FIGS. 7-12. The arm 610 may be lockable into a plurality of positions using gears, racks, pinions, and/or other combinations of mechanical components, where force from the user and/or a motor may allow the bar 616 to be positioned and a force on the arm 610 from the mechanical component(s) may maintain the bar 616 at the desired position.

[0042] FIGS. 9-12 are side views of example orientations of an example arm 610 and an example light source 612 of an example display device 600. Referring to FIG. 9, the display device 600 is supported by a stand 660 having a foot plate 662. The stand 660 connected to the housing 606 opposite the side at which the display panel 602 emits light. The housing 606 includes walls defining a recess 608. An arm 610 extends from the housing 606 and is rotatably coupled to the housing 606 via a hinge 628. The light source 612 is attached to the bar 616, and the bar 616 is rotatably coupled to the arm 610 via hinge 630. The light source 612 is orientable into a plurality of positions, such as the positions depicting in FIGS. 9-12. Each of the operational modes for the light sources as discussed below may be defined by a light profile storing attributes corresponding to how to operate light according to the various descriptions herein. [0043] In FIG. 9, the arm 610 is rotated to a position leaning towards the direction that the display panel 602 is facing and away from the recess 608 while the light source 612 is rotated to emit light in a direction substantially perpendicular to the light emitted from the display panel 602. In this manner, the light emitted from the light source 612 is emitted towards the foot plate 662 of the stand 660 (or towards a desk on which the display device 600 is resting, for example). In this manner, the light source 612 may be used in a desk light operational mode where a white color light is emitted from the light source (e.g., to act as a desk light). In some examples, the white light sources are on while the color light sources are off.

[0044] In FIG. 10, the arm 610 is rotated to the same position as shown in FIG. 9. However, the bar 616 is rotated upwards with respect to the arm 610, such that the light emitted from the light source 612 is emitted in a substantially parallel direction of light emitted from the display panel 602. In this manner, the light source 612 may be in a portrait light operational mode (e.g. , to act as a light for taking a portrait photo). Indeed, in some examples, a controller may determine the operational mode of the light source based on both the orientation of the arm 610 and the orientation of the bar 616 and/or light source 612. In some examples, the white light sources are on while the color light sources are off. In other examples, the color light sources may adapt the white light to assist colors of a camera receiving images of an object illuminated by the light source 612.

[0045] In FIG. 11 , the arm 610 is rotated towards the recess 608, but is not located within the recess 608. In this orientation, the light emitted from the light source 612 is in a direction oblique to corresponding to the direction of light emitted from the display panel 602 when the arm 610 is on a side of the display device 600 opposite where the display panel 602 is facing (e.g., the arm is rotated to the back side of the housing 606 of the display device 600). In this manner, the light source 612, may be used in an environmental light operational mode to, for example, illuminate colors displayed on the display panel towards a wall or other object in the room in which the display device 600 is located (e.g., to illuminate the environment in which the display device is located). In some examples, the white light sources are off while the color light sources are on. In some examples of environmental light profile may include a color profile that rotates through a range of colors.

[0046] In FIG. 12, the arm 610 is rotated into the recess 608. In this orientation, the light emitted from the light source 612 is in a direction opposite of the light emitted from the display panel when in the recess position (e.g., located within the recess 608). In this manner, the light source 612 may be used in a device illumination operational mode to project aesthetic colors around the display as desired by the user. In some examples, In some examples, the white light sources are off while the color light sources are on and/or operates the lights to in a manner similar to the environment light profile mode, such as fluctuating light through a range of colors or maintaining a static color illumination. In some examples, the light sources 612 may automatically turn off when the bar 616 is placed into the recess 608, which may be represented by an inactive mode.

[0047] As shown herein, the apparatus and methods described herein allow for lighting custom izations based on orientation of the light sources. In this manner, a display device may assist with additional lighting with the display panel to provide various operational modes to be operated in based on the orientation of the arm to which the light sources are coupled, as desired by the user. Such customizable ability of environmental lighting may assist a user to use the display device for multiple types of activities without using secondary or further additional lighting for each activity.
