[0001] Background and Related Technology

[0002] Wireless electronic devices offer users an increased level of freedom while remaining connected to personal and professional communications. Conventional foldable laptops use a base portion containing a keyboard to support the display. This form factor requires a base to support the display and limits the options for positioning and posing the electronic device.

[0003] Portable electronic devices having hinges or selectively removable connections that allow for a wider variety of positions and postures provide users with greater freedom to utilize the electronic device in different applications throughout the day. Summary of the Invention

[0004] In some embodiments, a portable electronic device includes a plurality of optical modules located within a housing or support of the electronic device body. In some postures or positions of the electronic device, at least one of the optical modules is obscured by another portion of the electronic device. In some embodiments, the portions of the electronic device body are connected and supported relative to each other by a hinge. In some embodiments, the portable electronic device illuminates one or more of the optical modules based on the posture state of the hinge. The portable electronic device uses the posture state to dynamically change the illuminated optical module so that the optical module remains visible during posture changes.

[0005] In some embodiments, a method of selectively illuminating a portion of an electronic device includes obtaining a posture state of a hinge supporting a display cover relative to a base of the electronic device and illuminating an optical module located on an outer surface of the electronic device based on a hinge position of the posture state.

[0021] The present disclosure generally relates to systems and methods for illuminating optical modules on electronic devices. More specifically, the present disclosure relates to illuminating one or more optical modules on an exterior surface of an electronic device based on the posture state of a hinge of the electronic device. In some embodiments, the posture state includes the hinge position. In some embodiments, the posture state includes the hinge position and the orientation of the electronic device. Some portable electronic devices include an illuminated indicia integrated into the housing that is illuminated when the electronic device is powered on and / or in use. In some positions and / or postures, the illuminated indicia is obscured by another portion of the electronic device.

[0022] The optical module includes a light source that illuminates the optical module when an electric current is applied to the light source. The electronic device can selectively illuminate the optical module based on the posture state of the electronic device. In some embodiments, the optical module is a thin optical module that does not add significant thickness to the housing of the electronic device. The thinness of the optical module allows the optical module or multiple optical modules to be positioned on the outer surface of the electronic device. The electronic device can illuminate one or more optical modules based on the portions of the outer surface that are visible in the current posture of the electronic device. In some embodiments, the electronic device illuminates one optical module at a time, changing the position of the illuminated optical module based on the posture of the electronic device. In some embodiments, the electronic device illuminates more than one optical module from a plurality of optical modules at a time, changing the position of the illuminated optical modules based on the posture of the electronic device. In at least one embodiment, the electronic device illuminates one optical module at a time, and more than one optical module is illuminated simultaneously during a transition period.

[0023] Figure 1 1 is a perspective view of an embodiment of an electronic device according to the present disclosure. In some embodiments, electronic device 100 has a first portion 102 and a second portion 104 that are removably connected to each other. Electronic device 100 includes various components located in or on various parts of electronic device 100, which communicate data via one or more buses and interfaces. Examples of components include processor(s) 106, input device(s) 108, display(s) 110, hardware storage device(s) 112, communication device(s) 114, and other components.

[0024] In some embodiments, the processor(s) 106 are a central processing unit (CPU) that performs general computing tasks for the electronic device 100. In some embodiments, the processor(s) 106 are a system on a chip (SoC) or a portion of a system on a chip (SoC) dedicated to controlling or communicating with one or more subsystems of the electronic device 100.

[0025] In some embodiments, the input device(s) 108 are a mouse, stylus, touchpad, touch-sensitive device, touch-sensitive display, keyboard, or other input human interface device. In some embodiments, the display(s) 110 are a liquid crystal display (LCD), a light emitting diode (LED) display, a thin film transistor (TFT) display, or other display. In some embodiments, the display 110 is integrated into the electronic device 100, such as a Figure 1 As explained in the embodiments of .

[0026] In some embodiments, hardware storage device(s) 112 are non-volatile storage devices including any of RAM, ROM, EEPROM, CD-ROM or other optical disk storage (such as CDs, DVDs, etc.), magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store desired program code means in the form of computer-executable instructions or data structures and that can be accessed by a general purpose or special purpose computer.

[0027] In some embodiments, an electronic device has multiple potential postures in which a user can use the electronic device. In some embodiments, the electronic device has a laptop posture in which a first portion is supported by a hinge connecting the first portion to a second portion about a first hinge axis. In at least one embodiment, the first portion is a display cover that contains and supports a display of the electronic device, and the second portion is a base that contains at least one input device of the electronic device. The laptop posture positions the display facing the user in a conventional laptop configuration. In the laptop posture, a first optical module located on an outer surface of the first portion (e.g., the display cover) can be visible and illuminated.

[0028] Figure 1 and Figure 2-1 The electronic device 100 is shown in a laptop position with the first portion 102 supported relative to the second portion 104 by the hinge 116 at angular positions about a first hinge axis 118. The hinge 116 allows friction about the first hinge axis 118 to support the first portion in various positions and angles while the first optical module 120 is visible. When the first optical module 120 is visible in the laptop configuration, the electronic device 100 illuminates the first optical module 120, which projects a light-emitting logo or other symbol from the first portion 102.

[0029] Figure 2-2 Shown Figure 1 and Figure 2-1 An example embodiment of an electronic device 100 is provided in which the first optical module 120 is dimmed by the electronic device 100. In some embodiments, the first optical module 120 is located on the outer surface 121 of the first portion 102 but is layered beneath a light-transmitting material. The light-transmitting material obscures the first optical module 120 when it is dimmed, but allows light to pass through the light-transmitting material when the optical module is illuminated.

[0030] In some embodiments, the electronic device includes a processor that communicates data with other components of the electronic device, including but not limited to input device(s), a display, hardware storage devices, a power supply, optical modules(s), one or more posture and / or orientation sensors, communication devices, or other electronic components.

[0031] The electronic device has other postures besides the laptop posture, including a presentation or drafting posture, in which a first portion is supported by a third portion, such as a support, that connects the first portion to a second portion. The third portion is connected to the second portion about a first hinge axis, and the third portion is connected to the first portion about a second hinge axis. In some embodiments, the third portion rotating about the first hinge axis allows the first portion to move longitudinally relative to the second portion. For example, the first portion having a display can be positioned above the second portion and closer to the user to facilitate drafting on the touch-sensitive display.

[0032] like Figure 3 As shown, in the drafting posture, the first optical module (e.g., Figure 2-1 120) can be obscured or oriented downward, thereby limiting the visibility of the first optical module. When the first portion 102 is moved over the second portion 104 via the third portion 124, the second optical module 122 located on the third portion 124 (e.g., the support) can be illuminated when the hinge position about the first hinge axis 118 and / or the second hinge axis 126 indicates that the electronic device 100 is in the drafting posture. In some embodiments, the second optical module 122 can then shine upward and outward from the electronic device in a direction opposite to the user. In some embodiments, the second optical module 122 and the first optical module (e.g., Figure 2-1120) are both covered by the light-transmitting material on the outer surfaces of the first portion 102 and the third portion 124 so that both the second optical module 122 and the first optical module are visible only when illuminated. In some embodiments, the light-transmitting material is continuous between the first portion 102 and the third portion 124 (e.g., a single continuous piece of light-transmitting material bridging the second hinge axis 126). In such embodiments, when the electronic device 100 is in the laptop position, as in Figure 2-1 As shown, the first optical module 120 is illuminated and the second optical module 122 is not visible, and the outer surface 121 has a continuous appearance, while in Figure 3 In the illustrated drafting pose, the first optical module is not visible and the second optical module 122 is illuminated on the third portion 124 .

[0033] In some embodiments, the hinge position is measured by a sensor located in the hinge at or near the first hinge axis 118 or the second hinge axis 126. For example, the hinge may include a Hall effect sensor in which the magnetic force measured by the sensor varies with rotation about the hinge axis 118, 126; a potentiometer in which the electrical potential measured by the sensor varies with rotation about the hinge axis 118, 126; a contact array positioned about the hinge axis 118, 126 to measure the position of the first portion 102 relative to the third portion 124 or the position of the third portion 124 relative to the second portion 104; or other rotational position or motion sensor.

[0034] In some embodiments, the hinge position is measured by a sensor located outside the hinge and away from the first hinge axis 118 or the second hinge axis 126. For example, the electronic device 100 may include an infrared optical sensor that measures the position of the first portion 102 relative to the second portion 104. In other examples, the second portion 104 may include a Hall effect sensor that detects the position of the lower edge of the first portion 102 relative to the second portion 104, thereby indirectly measuring the necessary rotational position of the first hinge axis 118 and the second hinge axis 126.

[0035] Figure 41 is a perspective view of electronic device 100 further positioned in a tablet position, with first portion 102 flipped over with display 110 oriented away from second portion 104. For example, outer surface 121 of first portion 102 can be oriented toward second portion 104 and third portion 124, with first and second optical modules obscured and not visible. In such an embodiment, the electronic device illuminates third optical module 128 located on an outer surface of second portion 104 opposite first portion 102 and third portion 124. In other words, third optical module 128 can be located on the bottom surface of the base so that when a user is viewing and / or interacting with display 110, third optical module 128 can be illuminated and visible on a surface opposite display 110.

[0036] The optical module itself includes a transparent element that allows light to pass through. The transparent element can guide light from the light source through the transparent element and emit the light to provide a substantially uniform luminous appearance from the optical module. In some embodiments, the visible illumination of the optical module from the transparent element onto a surface other than the electronic device is uniform within a 10% variation. In some embodiments, the visible illumination of the optical module from the transparent element onto a surface other than the electronic device is uniform within a 5% variation. In some embodiments, the visible illumination of the optical module from the transparent element onto a surface other than the electronic device is uniform within a 2% variation.

[0037] Figures 5-1 to 5-3 Embodiments of optical modules with different covers according to the present disclosure are shown. Figure 5-1 is a perspective view of an embodiment of an optical module 220 that includes a transparent element 230, a light source 232 or array of light sources positioned to edge-light the transparent element 230, an optical film 234 positioned over a portion of the transparent element 230 from which light from the light source 232 will exit the optical module 220, and electrodes that power the light source 232. In some embodiments, edge-lighting the transparent element 230 with the light source 232 allows the optical module 220 to have a smaller thickness in a direction perpendicular to the surface of the transparent element 230.

[0038] In some embodiments, the transparent element of the optical module is acrylic. In some embodiments, the transparent element of the optical module is another polymer. In some embodiments, the transparent element of the optical module is glass.

[0039] The transparent element can be illuminated by a light source positioned adjacent to the transparent element so as to edge-light the transparent element. In some embodiments, the light source comprises a light emitting diode (LED). In some embodiments, the light source is a plurality of LEDs. For example, the optical module may comprise an LED array that provides white light to illuminate the transparent element. In some examples, the light source provides one or more light colors to illuminate the transparent element.

[0040] The wavelength(s) of light provided by the light source may be adjustable or selectable. In some embodiments, the wavelength of light is user-selectable to customize the color of the optical module to user preferences. For example, software control may allow a user to select different specific LEDs within an LED array to control the wavelength or range of wavelengths emitted by the LED array. In some embodiments, the wavelength of light varies based on the operating mode of the electronic device. For example, when used in a performance or gaming electronic device, the optical module may change from standard white light to a red wavelength when the electronic device is operating in high-performance or gaming mode. In other examples, the optical module may change to a green wavelength when the electronic device is operating in a battery saver mode. In other examples, when the electronic device is charging, the optical module may change brightness (e.g., periodically pulsating) to indicate battery charging.

[0041] In some embodiments, an optical film or covering is applied to at least a portion of the transparent element. In some examples, the optical film modifies the wavelength of light exiting the optical module. For example, different areas of the optical module may have different optical films that provide different transmitted colors. In other examples, the optical film scatters or diffuses light exiting the transparent element to provide a more uniform appearance to the optical module when illuminated.

[0042] As described herein, the optical module according to the present disclosure can be thin so as to be positioned in the housing of a portable electronic device. In some embodiments, the stack of transparent elements, (all) optical films, light sources, and electrodes on which the light sources are located has a total thickness perpendicular to the plane of the optical module, and the total thickness is within the range of an upper limit, a lower limit, or an upper and lower limit of any one of the following: 0.5 millimeters (mm), 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.7 mm, 2.0 mm, or any value therebetween. For example, the thickness of the optical module can be less than 2.0 mm. In other examples, the thickness of the optical module can be less than 1.5 mm. In other examples, the thickness of the optical module can be between 0.5 mm and 1.5 mm. In at least one example, the thickness of the optical module is 1.2 mm. In the case where multiple optical modules are positioned in the housing of an electronic device, a thin optical module can allow the optical module to be placed in more locations within the electronic device even when almost all the internal space in a thin and / or light electronic device is used.

[0043] When an optical module is located behind a mask or other opaque material in an electronic device housing, the bottom surface of the mask can create visible optical artifacts in the optical module. For example, the edge of the mask can be visible in reflections on the back surface of a transparent element. In some embodiments, reflections and other optical artifacts are reduced by applying a non-reflective coating or paint at or near the edge of the mask.

[0044] Figure 5-2 is a mask 238 positioned over the optical film 234. Figure 5-1 238. Because the mask 238 itself may be reflective, repeated reflections within the transparent element can be reduced or prevented by applying a black or other non-reflective coating 240 between the mask 238 and the optical film 234. In some embodiments, the black coating 240 is applied to the optical film 234. In some embodiments, the black coating 240 is applied to the mask 238.

[0045] In some embodiments, the optical module is obscured by a light-transmissive material. The light-transmissive material allows light from the optical module to pass through and be visible to the user when the optical module is illuminated, but hides the optical module when the optical module is not illuminated. In this way, the optical module can selectively appear on the outer surface of the electronic device when illuminated or appear to move when a first optical module is dimmed and a different optical module is illuminated.

[0046] In some embodiments, the light-transmitting material is a light-transmitting fabric, such as a woven organic or synthetic fiber. In some examples, the fabric is wool, cotton, polyester, nylon, or other fibers. In some embodiments, the light-transmitting material is a perforated material. In some examples, the perforated material allows light from the optical module to pass through the perforations and is otherwise opaque to shield the optical module when it is dimmed. The perforated material can be leather, polymer, vinyl, metal, or other continuous material. In at least one example, the light-transmitting material is part of the housing of the electronic device, such as a perforated area of ​​an aluminum housing. In at least another example, the light-transmitting material is a discrete layer applied to the housing of the electronic device, such as light-transmitting fabric or perforated leather applied to an aluminum housing.

[0047] Figure 5-3is a perspective view of an optical module 220 having a light transmissive material positioned above an optical film 234. Although the figure shows the light transmissive material 242 positioned spaced apart from the optical film 234, in some embodiments, the light transmissive material 242 can be adhered directly to the optical film 234. As described herein, the light transmissive material 242 can be a porous or non-continuous piece of material that allows a portion of incident light to be transmitted therethrough. In some embodiments, the light transmissive material 242 is a substantially opaque material such as leather, a polymer (e.g., ABS), or a metal that includes a plurality of perforations 244. In some embodiments, the light transmissive material 242 is a reference to Figure 5-2 In some embodiments, the light-transmissive material 242 is used in conjunction with the discrete mask 238, and the position, size, and arrangement of the perforations are substantially uniform so as not to interfere with the image generated by the mask 238.

[0048] Figure 6 An embodiment of a method for controlling an optical module in an electronic device is shown. In some embodiments, the method 346 of controlling illumination of an optical module in an electronic device includes obtaining (348) a posture state of a hinge of the electronic device. The posture state of the hinge that supports a display cover relative to a base of the electronic device indicates a position of the display cover (e.g., a first portion) relative to the base (e.g., a second portion). By measuring, receiving, or otherwise obtaining the hinge position, the electronic device can determine whether the first optical module is visible to a user or to other individuals in the user's environment.

[0049] The method further includes illuminating (350) an optical module located on an outer surface of the electronic device based on the posture state of the hinge. For example, when the first hinge axis is between 5° and 150° and the second hinge axis is at 0° (e.g., closed), the first optical module is illuminated, and when the first hinge axis is outside 5° to 150° or the second hinge axis is not at 0°, the first optical module is dimmed. In another example, when the sum of the angular positions of the first hinge axis and the second hinge axis is between 5° and 150°, the first optical module is illuminated, and when the sum of the angular positions of the first hinge axis and the second hinge axis is less than 5° or greater than 150°, the first optical module is illuminated.

[0050] As in Figure 7As shown in the flowchart of , in some embodiments, method 446 further includes obtaining (448) a posture state of a hinge of the electronic device and obtaining (452) an orientation state of the electronic device as part of the posture state. For example, an accelerometer, gyroscope, or other orientation sensor can provide an orientation state indicating whether a user has picked up or tilted the electronic device. In some examples, the optical module is located on the bottom surface of the base of the electronic device. The optical module on the bottom surface can be illuminated when the hinge position indicates that the device is in a tablet posture and the orientation state indicates that the user has picked up the electronic device and the electronic device is not oriented horizontally on the work surface. In other examples, a first optical module on the outer surface of the first portion and a second optical module on the bottom surface can both be illuminated when the hinge position indicates that the device is in a laptop posture and the orientation state indicates that the user has rotated the electronic device to a book-like orientation (e.g., the hinge axis is oriented vertically). By selectively illuminating (450) the optical modules based on a combination of the hinge position and the electronic device orientation, the electronic device can prevent illuminating obscured or invisible optical modules and thereby reduce energy consumption and heat generation.

[0051] In some embodiments, another method 554 of controlling illumination of optical modules in an electronic device includes obtaining (548) a posture state of a hinge supporting a display cover relative to a base of the electronic device and then selectively illuminating (556) one or more of a plurality of optical modules, such as Figure 8 . Multiple optical modules may allow an electronic device to selectively illuminate optical modules that are visible in the current posture and / or orientation of the electronic device. For example, a first optical module located on an outer surface of a display cover (e.g., a first portion) is visible to various persons in the user's surroundings when the electronic device is in a laptop posture, a second optical module located on an outer surface of a support (e.g., a third portion) is visible to various persons in the user's surroundings when the electronic device is in a drafting or presenting posture, and a third optical module located on an outer surface of a base (e.g., a second portion) is visible to various persons in the user's surroundings when the electronic device is in a tablet posture.

[0052] Illuminating or dimming the optical module can be performed after a delay. For example, the optical module(s) can remain illuminated or dimmed when the user moves the first portion of the electronic device relative to the second portion, so that the electronic device waits until the posture state is constant within a time period and then illuminates or dims the optical module(s). In other examples, the optical module(s) can remain illuminated or dimmed until the posture state indicates that the electronic device is in the same posture within a time period, even if the hinge position and / or device orientation changes within the posture. In some embodiments, the delay is within a range having an upper limit, a lower limit, or both an upper limit and a lower limit of 50 milliseconds (ms), 100ms, 200ms, 300ms, 400ms, 500ms, or any value therebetween. For example, the delay may be greater than 50ms. In other examples, the delay is less than 500ms. In some examples, the delay is between 50ms and 500ms. In at least one example, the delay is 100ms.

[0053] The delay in lighting or dimming the optical module can improve the user experience. For example, the delay requires the electronic device to be positioned in a specific posture and / or orientation for a period of time before the optical module is illuminated or dimmed. In the absence of a delay period, the electronic device can be moved from a tablet posture ( Figure 4 shown) moves through the drafting pose ( Figure 3 2 ) through the laptop position (shown in FIG. 2 ) to the closed position will result in rapid succession of illumination and dimming of each of the optical modules 120, 122, 126. The resulting flickering of the optical modules during rapid posture changes may be undesirable, and the delay period allows the electronic device to progress through the postures and illuminate or dim the optical modules only when the posture change has stopped or slowed.

[0054] In some embodiments that include illuminating a first optical module and dimming a second optical module based on a posture state, the first and second optical modules are illuminated concurrently. The first and second optical modules can be illuminated concurrently for an overlap period that is within a range having an upper limit, a lower limit, or both of 100 ms, 200 ms, 300 ms, 400 ms, 500 ms, 750 ms, 1.0 second, or any value therebetween. For example, the overlap period can be greater than 100 ms. In other examples, the overlap period is less than 1.0 second. In some examples, the overlap period is between 100 ms and 1.0 second. In at least one example, the overlap period is 500 ms.

[0055] Some embodiments illuminate and / or dim the optical module approximately instantaneously, or as quickly as the electronic device allows. In some embodiments, the optical module is illuminated or dimmed within a fade period. The first optical module and the second optical module can be illuminated concurrently within a fade period, and the fade period is within a range having an upper limit, a lower limit, or both an upper limit and a lower limit, including any of the following: 100ms, 200ms, 300ms, 400ms, 500ms, 750ms, 1.0 second, or any value therebetween. For example, the fade period can be greater than 100ms. In other examples, the fade period is less than 1.0 second. In some examples, the fade period is between 100ms and 1.0 second. In at least one example, the fade period is 500ms.

[0056] As described herein, the light source of the optical module may include a plurality of light sources, such as an LED array. The light source array may allow the optical module to be illuminated or dimmed from a first side to a second side by sequentially illuminating or dimming the LEDs, such as Figure 9 In some embodiments, the sequential dimming of the illuminated LEDs in the first optical module 120 combined with the sequential illumination of the LEDs in the second optical module 122 provides the effect of an illuminated portion of a logo or other symbol sliding from the first portion 102 down to the second portion 104, and can provide the appearance that the logo or other illuminated symbol moves across the exterior surface of the electronic device as gestures change.

[0057] Industrial Applicability

[0058] The present disclosure generally relates to systems and methods for illuminating optical modules on electronic devices. More specifically, the present disclosure relates to illuminating one or more optical modules on an exterior surface of an electronic device based on the posture state of a hinge of the electronic device. In some embodiments, the posture state includes the hinge position. In some embodiments, the posture state includes the hinge position and the orientation of the electronic device.

[0059] The optical module includes a light source that illuminates the optical module when an electric current is applied to the light source. The electronic device can selectively illuminate the optical module based on the posture state of the electronic device. In some embodiments, the optical module is a thin optical module that does not add significant thickness to the housing of the electronic device. The thinness of the optical module allows the optical module or multiple optical modules to be positioned on the outer surface of the electronic device. The electronic device can illuminate one or more optical modules based on the portions of the outer surface that are visible in the current posture of the electronic device. In some embodiments, the electronic device illuminates one optical module at a time, changing the position of the illuminated optical module based on the posture of the electronic device. In some embodiments, the electronic device illuminates more than one optical module from a plurality of optical modules at a time, changing the position of the illuminated optical modules based on the posture of the electronic device. In at least one embodiment, the electronic device illuminates one optical module at a time, and more than one optical module is illuminated simultaneously during a transition period.

[0060] In some embodiments, an electronic device has multiple potential postures in which a user can use the electronic device. In some embodiments, the electronic device has a laptop posture in which a first portion is supported by a hinge connecting the first portion to a second portion about a first hinge axis. In at least one embodiment, the first portion is a display cover that contains and supports a display of the electronic device, and the second portion is a base that contains at least one input device of the electronic device. The laptop posture positions the display facing the user in a conventional laptop configuration. In the laptop posture, a first optical module located on an outer surface of the first portion (e.g., the display cover) can be visible and illuminated.

[0061] The electronic device includes a processor that communicates data with other components of the electronic device, including but not limited to input device(s), a display, a hardware storage device, a power supply, an optical module(s), one or more posture and / or orientation sensors, a communication device, or other electronic components. In some embodiments, the hardware storage device has stored thereon instructions that, when executed by the processor, cause the processor to perform any of the methods described herein.

[0062] The electronic device has other postures besides the laptop posture, including a presentation or drafting posture, in which a first portion is supported by a third portion, such as a support, that connects the first portion to a second portion. The third portion is connected to the second portion about a first hinge axis, and the third portion is connected to the first portion about a second hinge axis. In some embodiments, the third portion rotating about the first hinge axis allows the first portion to move longitudinally relative to the second portion. For example, the first portion having a display can be positioned above the second portion and closer to the user to facilitate drafting on the touch-sensitive display.

[0063] In the drafting posture, the first optical module that is illuminated in the laptop posture may be blocked or oriented downward, thereby limiting visibility of the first optical module. The second optical module located on the third portion (e.g., the support member) may be illuminated when the hinge position about the first hinge axis and / or the second hinge axis of the electronic device indicates that the electronic device is in the drafting posture.

[0064] The electronic device can also be positioned in a tablet position with the first portion flipped relative to the second portion. For example, the outer surface of the first portion can be oriented toward the second portion, with the first and second optical modules obscured and invisible. In such an embodiment, the electronic device illuminates a third optical module located on an outer surface of the second portion opposite the first and third portions. In other words, the third optical module can be located on the bottom surface of the base so that when a user is viewing and / or interacting with the display, the third optical module can be illuminated and visible on the surface opposite the display.

[0065] The optical module includes a transparent element that allows light to pass through. The transparent element can guide light from a light source through the transparent element and emit the light to provide a substantially uniform luminous appearance from the optical module. In some embodiments, visible illumination of the electronic device from the transparent element by the optical module is uniform within a 10% variation. In some embodiments, visible illumination of the electronic device from the transparent element by the optical module is uniform within a 5% variation.

[0066] In some embodiments, visible illumination of the electronic device from the transparent element by the optical module is uniform within a 2% variation.

[0067] In some embodiments, the transparent element of the optical module is acrylic. In some embodiments, the transparent element of the optical module is another polymer. In some embodiments, the transparent element of the optical module is glass.

[0068] The transparent element can be illuminated by a light source positioned adjacent to the transparent element so as to edge-light the transparent element. In some embodiments, the light source comprises a light emitting diode (LED). In some embodiments, the light source is a plurality of LEDs. For example, the optical module may comprise an LED array that provides white light to illuminate the transparent element. In some examples, the light source provides one or more light colors to illuminate the transparent element.

[0069] The wavelength(s) of light provided by the light source may be adjustable or selectable. In some embodiments, the wavelength of light is user-selectable to customize the color of the optical module to user preferences. In some embodiments, the wavelength of light varies based on the operating mode of the electronic device. For example, when used in a performance or gaming electronic device, the optical module may change from standard white light to a red wavelength when the electronic device is operating in high-performance or gaming mode. In other examples, when the electronic device is operating in a battery-saving mode, the optical module may change to a green wavelength. In other examples, when the electronic device is charging, the optical module may change brightness (e.g., periodically pulsating) to indicate battery charging.

[0070] In some embodiments, an optical film or covering is applied to the transparent element. In some examples, the optical film modifies the wavelength of light exiting the optical module. In other examples, the optical film scatters or diffuses the light exiting the transparent element to provide a more uniform appearance to the optical module when illuminated.

[0071] As described herein, according to the optical module of the present disclosure can be thin so as to be positioned in the housing of a portable electronic device. In some embodiments, the stack of transparent element, (all) optical film, light source, and the electrode on which the light source is located has a total thickness perpendicular to the plane of the optical module, and this total thickness is within the range of an upper limit, a lower limit, or an upper and lower limit of any one of the following: 0.5 millimeter (mm), 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.4mm, 1.7mm, 2.0mm, or any value therebetween. For example, the thickness of the optical module can be less than 2.0mm. In other examples, the thickness of the optical module can be less than 1.5mm. In other examples, the thickness of the optical module can be between 0.5mm and 1.5mm. In at least one example, the thickness of the optical module is 1.2mm.

[0072] When an optical module is located behind a mask or other opaque material in an electronic device housing, the bottom surface of the mask can create visible optical artifacts in the optical module. For example, the edge of the mask can be visible in reflections on the back surface of a transparent element. In some embodiments, reflections and other optical artifacts are reduced by applying a non-reflective coating or paint at or near the edge of the mask.

[0073] In some embodiments, the optical module is shielded by a light-transmitting material.

[0074] The light-transmissive material allows light from the optical module to pass through and be visible to the user when the optical module is illuminated, but hides the optical module when the optical module is not illuminated. In this way, the optical module can selectively appear on the outer surface of the electronic device when illuminated or appear to move when a first optical module is darkened and a different optical module is illuminated.

[0075] In some embodiments, the light-transmitting material is a light-transmitting fabric, such as a woven organic or synthetic fiber. In some examples, the fabric is wool, cotton, polyester, nylon, or other fibers. In some embodiments, the light-transmitting material is a perforated material. In some examples, the perforated material allows light from the optical module to pass through the perforations and is otherwise opaque to shield the optical module when it is dimmed. The perforated material can be leather, polymer, vinyl, metal, or other continuous material. In at least one example, the light-transmitting material is part of the housing of the electronic device, such as a perforated area of ​​an aluminum housing. In at least another example, the light-transmitting material is a discrete layer applied to the housing of the electronic device, such as light-transmitting fabric or perforated leather applied to an aluminum housing.

[0076] In some embodiments, a method for controlling illumination of an optical module in an electronic device includes obtaining a posture state of a hinge of the electronic device. The posture state of the hinge supporting a display cover relative to a base of the electronic device indicates a position of the display cover (e.g., a first portion) relative to the base (e.g., a second portion). By measuring, receiving, or otherwise obtaining the hinge position, the electronic device can determine whether a first optical module is visible to a user or to other individuals in the user's environment.

[0077] The method further includes illuminating an optical module located on an outer surface of the electronic device based on the posture state of the hinge. For example, when the first hinge axis is between 5° and 150° and the second hinge axis is at 0° (e.g., closed), the first optical module is illuminated, and when the first hinge axis is outside 5° to 150° or the second hinge axis is not at 0°, the first optical module is dimmed. In another example, when the sum of the angular positions of the first hinge axis and the second hinge axis is between 5° and 150°, the first optical module is illuminated, and when the sum of the angular positions of the first hinge axis and the second hinge axis is less than 5° or greater than 150°, the first optical module is illuminated.

[0078] In some embodiments, the method further includes obtaining an orientation state of the electronic device as part of the posture state. For example, an accelerometer, gyroscope, or other orientation sensor may provide an orientation state indicating whether a user has picked up or tilted the electronic device. In some examples, an optical module is located on the bottom surface of the base of the electronic device. The optical module on the bottom surface may be illuminated when the hinge position indicates that the device is in a tablet posture and the orientation state indicates that the user has picked up the electronic device and the electronic device is not oriented horizontally on a work surface. In other examples, a first optical module on the outer surface of the first portion and a second optical module on the bottom surface may both be illuminated when the hinge position indicates that the device is in a laptop posture and the orientation state indicates that the user has rotated the electronic device to a book-like orientation (e.g., the hinge axis is oriented vertically). By selectively illuminating the optical modules based on a combination of the hinge position and the orientation of the electronic device, the electronic device can prevent illuminating obscured or invisible optical modules and thereby reduce energy consumption and heat generation.

[0079] In some embodiments, the hinge position is measured by a sensor located in the hinge at or near the first hinge axis or the second hinge axis. For example, the hinge may include a Hall effect sensor in which the magnetic force measured by the sensor varies with rotation about the hinge axis; a potentiometer in which the electrical potential measured by the sensor varies with rotation about the hinge axis; a contact array positioned about the hinge axis to measure the position of the first portion relative to the third portion or the position of the third portion relative to the second portion; or other rotational position or motion sensors.

[0080] In some embodiments, a method of controlling illumination of an optical module in an electronic device includes selectively illuminating one or more of a plurality of optical modules. The plurality of optical modules may allow the electronic device to selectively illuminate optical modules that are visible in the current posture and / or orientation of the electronic device. For example, a first optical module located on an outer surface of a display cover (e.g., a first portion) is visible to persons in the user's surroundings when the electronic device is in a laptop posture, a second optical module located on an outer surface of a support (e.g., a third portion) is visible to persons in the user's surroundings when the electronic device is in a drafting or presenting posture, and a third optical module located on an outer surface of a base (e.g., a second portion) is visible to persons in the user's surroundings when the electronic device is in a tablet posture.

[0081] Illuminating or dimming the optical module can be performed after a delay. For example, the optical module(s) can remain illuminated or dimmed when the user moves the first portion of the electronic device relative to the second portion, so that the electronic device waits until the posture state is constant within a time period and then illuminates or dims the optical module(s). In other examples, the optical module(s) can remain illuminated or dimmed until the posture state indicates that the electronic device is in the same posture within a time period, even if the hinge position and / or device orientation changes within the posture. In some embodiments, the delay is within a range having an upper limit, a lower limit, or both an upper limit and a lower limit of 50 milliseconds (ms), 100ms, 200ms, 300ms, 400ms, 500ms, or any value therebetween. For example, the delay may be greater than 50ms. In other examples, the delay is less than 500ms. In some examples, the delay is between 50ms and 500ms. In at least one example, the delay is 100ms.

[0082] The delay in lighting or dimming the optical module can improve the user experience. For example, the delay requires the electronic device to be positioned in a specific posture and / or orientation for a period of time before the optical module is illuminated or dimmed. In the absence of a delay period, the electronic device can be moved from a tablet posture ( Figure 4 shown) moves through the drafting pose ( Figure 3 2 ) through the laptop position (shown in FIG. 2 ) to the closed position will result in rapid succession of illumination and dimming of each of the optical modules 120, 122, 126. The resulting flickering of the optical modules during rapid posture changes may be undesirable, and the delay period allows the electronic device to progress through the postures and illuminate or dim the optical modules only when the posture change has stopped or slowed.

[0083] In some embodiments that include illuminating a first optical module and dimming a second optical module based on a posture state, the first and second optical modules are illuminated concurrently. The first and second optical modules can be illuminated concurrently for an overlap period that is within a range having an upper limit, a lower limit, or both of 100 ms, 200 ms, 300 ms, 400 ms, 500 ms, 750 ms, 1.0 second, or any value therebetween. For example, the overlap period can be greater than 100 ms. In other examples, the overlap period is less than 1.0 second. In some examples, the overlap period is between 100 ms and 1.0 second. In at least one example, the overlap period is 500 ms.

[0084] Some embodiments illuminate and / or dim the optical module approximately instantaneously, or as quickly as the electronic device allows. In some embodiments, the optical module is illuminated or dimmed within a fade period. The first optical module and the second optical module can be illuminated concurrently within a fade period, and the fade period is within a range having an upper limit, a lower limit, or both an upper limit and a lower limit, including any of the following: 100ms, 200ms, 300ms, 400ms, 500ms, 750ms, 1.0 second, or any value therebetween. For example, the fade period can be greater than 100ms. In other examples, the fade period is less than 1.0 second. In some examples, the fade period is between 100ms and 1.0 second. In at least one example, the fade period is 500ms.

[0085] As described herein, the light source of the optical module can include multiple light sources, such as an array of LEDs. The light source array can allow the optical module to be illuminated or dimmed from a first side to a second side by sequentially illuminating or dimming the LEDs. In some embodiments, sequential dimming of the illuminated LEDs in the first optical module combined with sequential illumination of the LEDs in the second optical module provides a sliding effect and can provide the appearance of a logo or other illuminated symbol moving across the outer surface of the electronic device as gestures change.

[0086] In at least some embodiments, systems and methods according to the present disclosure allow for presentation of an illuminated optical module (eg, a logo or symbol) on an appropriate area of ​​an electronic device as the posture of the electronic device changes.
