Description

[0001] This application is a divisional application of the invention patent application with the application number 201810786949.7, the application date of July 18, 2018, and the invention name of "Hidden Input Area of Electronic Devices". Technical Field

[0002] The described embodiments generally relate to the input area of an electronic device. More specifically, the present embodiment relates to a structure for hiding or obscuring the presence of the input area. Background Art

[0003] In a computing system, an input device can be used to receive input from a user. Some traditional input devices include large buttons, keys, or other mechanical actuation structures. However, these types of input devices may lack flexibility or adaptability and can permanently indicate the presence of the input device within the computing system. Summary of the Invention

[0004] Embodiments of the present invention relate to an electronic device having a concealed or hidden input area.

[0005] In a first aspect, the present disclosure includes an electronic device. The electronic device includes a housing that defines an internal volume and has a wall that defines an input area having a micro-perforation array. The electronic device further includes a light source positioned within the internal volume and configured to propagate light through the micro-perforation array. The electronic device further includes a sensing element positioned within the internal volume and configured to detect an input received along the input area. The micro-perforation array is configured to be visually imperceptible when not illuminated by the light source. The micro-perforation array is further configured to display a symbol when illuminated by the light source.

[0006] Multiple feature improvements and other features apply to the first aspect and can be envisioned in accordance with the present disclosure. These feature improvements and other features can be used alone or in any combination. Thus, each of the following features to be discussed can, but need not, be combined with any other feature of the first aspect.

[0007] For example, in an embodiment, the housing can define a watch body having a first opening and a second opening. The electronic device can further include a display positioned within the first opening. The electronic device can further include a crown at least partially positioned within the second opening. The graphical output of the display can respond to: (i) rotation or translation of the crown; and (ii) an input received along the input area.

[0008] In another embodiment, the wall may define a top surface having a first opening and a second opening. An input area may be defined along the top surface. The electronic device may further include a display positioned within the first opening. The electronic device may further include a button positioned within the second opening. The graphical output of the display may be responsive to: (i) mechanical pressing of the button; and (ii) input received within the input area.

[0009] In other embodiments, the housing includes an upper portion pivotally coupled to a lower portion. The upper portion may define an opening, and the lower portion may include an input area. The electronic device may further include a display positioned within the opening. The display may be responsive to input received within the input area. Additionally or alternatively, the lower portion may define an array of key openings. Thus, the electronic device may further include an array of keycaps positioned along corresponding key openings of the array. The display may be responsive to mechanical pressing at one or more of the keycaps.

[0010] According to another embodiment, the wall includes a metal layer. Thus, the micro-perforation array may extend through the metal layer. In another case, the wall includes a translucent layer, and the electronic device further includes an opaque shielding layer positioned within the volume defined by the housing. Thus, the micro-perforation array may extend through the opaque shielding layer.

[0011] In another embodiment, the sensing element includes one or more of the following: (i) a tactile membrane switch; (ii) an electroactive polymer; (iii) a piezoelectric structure; (iv) a magnetic-based sensor; (v) a capacitance-based sensor; or (vi) an optical sensor.

[0012] In this regard, a second aspect of the present disclosure includes an electronic device. The electronic device includes a translucent layer defining an input area and configured to deform in response to a force input. The electronic device further includes an opaque shielding layer positioned below the translucent layer and having a micro-perforation array. The electronic device further includes a light source positioned below the translucent layer and configured to illuminate symbols on the input area by illuminating the micro-perforation array. The electronic device further includes a sensing element positioned below the translucent layer and configured to detect a force input at the input area. The micro-perforation array is visually imperceptible when not illuminated by the light source.

[0013] A number of feature improvements and other features apply to the second aspect and may be envisioned in accordance with the present disclosure. These feature improvements and other features may be used alone or in any combination. Thus, each of the following features to be discussed may, but need not, be used in combination with any other feature of the second aspect.

[0014] For example, in an embodiment, the translucent layer may form the outer surface of the housing, and the housing may define an internal volume of the electronic device. The opaque shielding layer may hide the internal volume of the housing. The micro-perforation array may allow light emitted by a light source to propagate through the opaque shielding layer. To facilitate the foregoing, the width of a given micro-perforation may be in the range of 30 micrometers to 80 micrometers. Additionally, the spacing between one or more micro-perforations may be in the range of 80 micrometers to 500 micrometers.

[0015] According to another embodiment, one or more of the micro-perforation arrays may be defined by non-linear edges of the opaque shielding layer. In some cases, at least one subset of the micro-perforation array may be defined by tapered sidewalls that extend through the thickness of the opaque shielding layer. The micro-perforation array may be arranged on the opaque shielding layer to jointly define at least one of the boundaries of alphanumeric characters or input regions. The micro-perforation array may be used to control the optical characteristics of the light propagating through the opaque shielding layer and thereby define the viewing angle of the symbol relative to the translucent layer.

[0016] In other embodiments, the symbol is a first symbol, and the light source includes an array of selectively operable light elements configured to illuminate: (i) the first symbol using a first subset of the micro-perforation array; and (ii) a second symbol using a second subset of the micro-perforation array. At least one micro-perforation of the micro-perforation array may belong to both the first subset and the second subset. The sensing element may be used to: (i) trigger a first switching event in response to a detected force input when the first symbol is illuminated; and (ii) trigger a second switching event in response to a detected force input when the second symbol is illuminated.

[0017] In this regard, a third aspect of the present disclosure includes an electronic device. The electronic device includes a translucent layer that forms the outer surface of the electronic device. The electronic device further includes a sensing element positioned within the electronic device and configured to detect an input along an input region defined by the outer surface. The electronic device further includes an opaque shielding layer positioned below the translucent layer and defining a micro-perforation array. The electronic device further includes a light source having an array of selectively operable light elements configured to illuminate the micro-perforation array. When not illuminated, the micro-perforation array is not visually perceptible. In a first mode, the light source may be configured to display a first illuminated symbol formed by the micro-perforation array. In a second mode, the light source may be configured to display a second illuminated symbol formed by the micro-perforation array.

[0018] Multiple feature improvements and other features apply to the third aspect and are contemplated in accordance with the present disclosure. These feature improvements and other features may be used alone or in any combination. Thus, each of the following features to be discussed may, but need not, be used in combination with any other feature of the third aspect.

[0019] For example, in an embodiment, the first illuminated symbol may correspond to a first subset of the micro-perforation array. Additionally, the second illuminated symbol may correspond to a second subset of the micro-perforation array. The electronic device may further include a display. The graphical output of the display may be modified in the following manner: (i) when the first symbol is illuminated, it is modified in a first manner in response to an input within the input region; and (ii) when the second symbol is illuminated, it is modified in a second manner in response to an input within the input region.

[0020] According to another embodiment, the first illuminated symbol may correspond to the boundary of the input region. Additionally, the second illuminated symbol may correspond to a modified boundary of the input region. The sensing element responds to: (i) an input received within the boundary when the first illuminated symbol is displayed at the translucent layer; and (ii) an input received within the modified boundary when the second illuminated symbol is displayed at the translucent layer.

[0021] In another embodiment, the sensing element may respond to deflection of the translucent layer caused by an input. The sensing element may at least partially include a haptic structure configured to generate a predetermined haptic output within the input region in response to a detected input. The light source may include an LED array positioned below the selective micro-perforations of the array.

[0022] In addition to the exemplary aspects and embodiments, additional aspects and embodiments will be apparent by reference to the drawings and by study of the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] The use of cross-hatching and / or shading in the drawings is generally used to clarify the boundaries between adjacent elements and also facilitates the readability of the drawings. Thus, the presence or absence of cross-hatching and / or shading does not represent or indicate any preference or requirement for a particular material, material property, element ratio, element size, commonality of similar illustrated elements, or any other characteristic, attribute, or property of any element shown in the drawings.

[0075] In addition, it should be understood that the proportions and dimensions (relative or absolute) of the various feature portions and elements (and their collections and groupings), as well as the boundaries, spacings, and positional relationships presented therebetween, are provided in the figures only to facilitate understanding of the various embodiments described herein and may not necessarily be presented or shown to scale and are not intended to indicate any preference or requirement for the embodiments shown, to exclude the embodiments described in connection therewith. Detailed Description

[0076] The following description includes sample systems, methods, and apparatuses embodying various elements of the present disclosure. However, it should be understood that the described disclosure may be implemented in many forms other than those described herein.

[0077] The present disclosure describes systems, devices, and techniques related to electronic devices having a concealed or hideable input area. The electronic device may include a housing wall or other housing component that forms an outer surface of the electronic device. The input area may be defined along the outer surface and may be configured to control the functions of the electronic device in response to inputs including force inputs, touch inputs, and / or proximity inputs. A microperforation array may be disposed on a portion of the input area. When illuminated or in an active state, the microperforations may display virtual keys, buttons, notification graphics, or other notations or symbols at the outer surface, thereby revealing the input area. When not illuminated or in a deactivated state, the microperforation array may be visually imperceptible or visible. In some cases, the outer surface may be substantially free of visual indication of the input area, and the input functions of the input area may be hidden.

[0078] As used herein, the term microperforation may be used to refer to small openings that, when arranged in an array or pattern of similar openings, are visually imperceptible when not illuminated and may display symbols or graphics when illuminated. For example, the microperforations may have a width of about 30 - 80 micrometers and thus be visually imperceptible or hidden from the user when not illuminated. In some cases, although the symbols or graphics are formed by an array of individual microperforations, the symbols or graphics may appear solid or uniform, and the individual microperforations may not be distinguishable when viewed with the naked eye (at an appropriate viewing distance).

[0079] As described herein, the outer shell wall may comprise and / or be formed by a translucent (e.g., light-transmissive) layer and / or a metal layer. For example, in an embodiment, the outer shell wall may comprise a translucent layer that may be a component of or form an outer shell of an electronic device and defines an outer surface having an input region. The translucent layer may be formed of one or more translucent materials, including, for example, glass, ceramic, plastic, or combinations thereof. As used herein, the term translucent or translucent layer may be used to refer to a material or layer of a characteristic structure that allows light to pass through and does not require the material or layer to be transparent, light-transmissive, or in other words, without scattering or absorbing some amount of light. As used herein, the term translucent generally may refer to an optically transparent, partially transparent, or in other words, a material or layer capable of transmitting light. Thus, as described herein, the translucent layer may be or form a component of the top shell of a laptop computer, which may be metal, plastic, glass, carbon fiber, ceramic, or other materials. For example, the translucent layer may extend through the thickness of the outer shell such that the inner surface is positioned within the internal volume defined by the outer shell. This may allow light to propagate between the interior and exterior of the electronic device through the translucent layer. The translucent layer may also be configured to deform in response to an input (e.g., a local section may translate inward in response to a force; this may not be perceptible haptically). This may allow an input component or other component to detect a force input received at the input region by measuring the bending or deflection of the translucent layer.

[0080] An opaque masking layer may be positioned along the inner surface of the translucent layer and control the propagation of light through the translucent layer. The opaque masking layer may be an ink, a coating, a substrate, a deposit, or other structure that impedes or blocks light. Thus, a micro-perforation array defined by the opaque masking layer may form channels or passages through the opaque masking layer that allow light to pass through the opaque masking layer and propagate toward the input region defined on the translucent layer. When illuminated, the micro-perforation array may define virtual keys within the input region by propagating light through the translucent layer in a manner similar to virtual keys. When not illuminated by a light source, the micro-perforation array may be visually imperceptible or invisible to the human naked eye, in part because the width, diameter, or other dimension of a given micro-perforation is about 30 - 80 microns. For example, the width may be the maximum dimension of the micro-perforation as measured on the outer surface of the device. This may allow the opaque masking layer to hide or conceal the input component positioned within the outer shell and thereby allow the translucent layer to resemble the outer shell of a device without markings, symbols, and / or other indications of the input region.

[0081] The micro-perforation array can be arranged on the opaque shielding layer in various ways. The micro-perforation array can be holes, openings, through-parts, and / or other circular or curved feature structures in the opaque shielding layer that allow light to pass through. However, the micro-perforation array can also be similar to various other shapes, including shapes with linear edges, shapes with non-linear edges, angled shapes, and / or irregular or asymmetric shapes. The micro-perforation array can be arranged to jointly define a virtual key or symbol such that illumination (from within the housing) causes the virtual key or symbol to appear within the input area. In other embodiments, the micro-perforation array can be arranged in a matrix (e.g., a dot matrix configuration), and a selective subset of the micro-perforation array can be illuminated to define various different virtual keys or symbols within the input area. The micro-perforation array can also be selectively illuminated to display a variable-sized boundary of the input area at the translucent layer.

[0082] The optical properties of the illuminated virtual key or symbol can be tuned or controlled using the micro-perforation array. This can include controlling or tuning the spacing, size, shape, and / or other features of the micro-perforation array to produce a desired visual effect. For example, and as described in more detail below, sharpness, contrast, brightness, color, optimal viewing angle, and / or other optical properties can depend at least in part on the shape, size, spacing, angle, or other physical properties of the micro-perforation array.

[0083] It should be understood that, as described herein, the micro-perforation array can be defined by other components and structures of the electronic device. For example, the micro-perforation array can be defined by the housing wall that forms the outer surface of the electronic device. The wall can be formed of a metal material (such as aluminum) that blocks or impedes the passage of light. Similar to the micro-perforation array defined by the opaque shielding layer, the micro-perforation array defined by the housing wall may not be visually perceptible when not illuminated and can display symbols or glyphs within the input area when illuminated from within the electronic device.

[0084] The input component includes a light source positioned below the micro-perforation array. The light source can include light-emitting diodes (LEDs), micro-LEDs, light guides, liquid crystal displays (LCDs), organic light-emitting diodes (OLEDs), fluorescent lamps, and / or other light-emitting elements that pass light through the opaque shielding layer and propagate the light towards the input area. As described in more detail below, the light source can be used to illuminate some or all of the micro-perforations to illuminate various different virtual keys or symbols of the translucent layer.

[0085] The illuminated virtual keys can display input areas and symbols that can indicate the functions of the electronic device. The translucent layer can be configured to receive inputs within the input areas that can be used to control the electronic device when illuminated. The sensing element or other components of the input assembly can be positioned within the device housing and configured to detect touch and / or force inputs received within the input areas at the translucent layer. The sensing element can be a non-contact sensor that measures various electrical parameters to detect touch and / or force inputs, including optical-based, magnetic-based, and capacitance-based sensors, as well as other non-contact sensors. In other cases, the sensing element can be a contact sensor, including tactile dome switches, strain gauges, piezoelectric or electroactive polymer (EAP) stacks, and the like, as well as other contact sensors. The sensing element can include multiple combinations of sensors, including contact sensors and non-contact sensors, that cooperate with each other to measure force and / or touch inputs received at the translucent outer surface. In some cases, the sensing element can measure local or global inward deflection or bending of the translucent layer and trigger corresponding switch events. The sensing element can also be configured to generate various haptic effects as described herein and / or be coupled to a separate haptic structure that produces haptic or tactile outputs along the input areas.

[0086] The haptic structure can generally be configured to simulate the haptic experience of a mechanical or physical key and / or produce haptic confirmation of an input and other effects. In one configuration, the haptic structure can be a retractable dome, spring, biasing element, and / or other mechanical actuation components that respond to an input. For example, a retractable dome or spring can be coupled to the translucent layer and bend and / or deform in response to a force input, thereby producing a desired haptic effect. In another configuration, the haptic structure can be an electromagnet, EAP, piezoelectric stack, voice coil actuator, and / or other electroactuation components that are coupled to the translucent layer and configured to produce a predetermined haptic output or effect at the input areas. In some cases, the haptic structure can be a component of the sensing element and / or the input assembly. For example, this can be the case when the haptic structure is a retractable dome that is a component of a tactile dome switch. Additionally, as described herein, multiple combinations of haptic structures can cooperate with each other to convey a desired haptic effect, including various combinations of mechanically actuated and electroactuated haptic structures suitable for a given application.

[0087] The input area can be dynamically adapted to control multiple functions of an electronic device. Multiple different or distinct virtual keys or symbols can be displayed within the input area to indicate or show the presence of multiple functions. For example, the input component can illuminate a first subset of a micro-perforation array to display a first symbol within the input area and subsequently illuminate a second subset of the micro-perforation array to display a second symbol within the input area. For example, in response to the processing unit of the electronic device associating the input area with a specific function, the light source of the input component can selectively illuminate the first subset and the second subset of the micro-perforation array. For example, the first symbol and the second symbol can indicate the functions associated with the input area. Additionally or alternatively, the first symbol and the second symbol can indicate the variable-sized boundaries of the input area, such as a first boundary and a modified boundary. In this regard, the input component can be configured to trigger a switch event corresponding to a specified function in response to detecting a force and / or touch input within the input area. In this regard, when the first symbol is illuminated, the input component can respond to an input received within the first boundary, and when the second symbol is illuminated, it can respond to an input received within the modified boundary. The tactile effects and optical characteristics of the illuminated symbols can also be adapted based on a given function of the input area.

[0088] The input area can be dynamically adapted based on the user's interaction with the illuminated virtual keys or symbols at the input area. For example, the illuminated keys can resemble knobs, slider switches, or other controls that accept continuous range inputs. The input component can detect an input corresponding to the manipulation of a knob or slider and dynamically adapt the illuminated symbols based on the detected manipulation (e.g., repositioning the knob or slider to a manipulated position). This can allow the input area to simulate physical controls that accept variable or range inputs, such as volume controls, scroll wheels, mixing bars, photo editing tools, etc.

[0089] In some embodiments, the micro-perforation array is used to illuminate an area that is not the input area. For example, and as described in more detail herein, the micro-perforation array can be used to display symbols or graphics along a portion of the outer surface of a device that is not configured to receive touch or force inputs. Such areas can be used to convey the status, mode, or other aspects of the operation of the electronic device.

[0090] It should be understood that the input regions described herein can be implemented relative to a variety of electronic devices. The electronic devices as described herein can be substantially any electronic device having a translucent layer or coupled to a translucent layer and configured to receive input, including laptop computers, desktop computers, smart phones, tablet computers, portable media players, watches, pencils, and / or other suitable electronic devices, including wearable devices. In some cases, the electronic device can be defined by a housing having one or more openings (at least a portion of which is translucent), the one or more openings surrounding or containing a display and / or buttons. In other embodiments, the electronic device can be a substantially mechanical component or segment, such as a wall, panel, dashboard, door, doorframe, etc. of a building. For example, a wall of a building can be used to define an input region and control various functions of the building, such as climate control, lighting, etc. Thus, the discussion of any electronic device is intended to be illustrative only.

[0091] Reference will now be made to the drawings that facilitate elucidating the various features of the present disclosure. The following description is presented for purposes of illustration and description. Additionally, the description is not intended to limit the various aspects of the invention to the forms disclosed herein. Accordingly, variations and modifications commensurate with the following teachings, technologies, and knowledge of the relevant art are within the scope of the various aspects of the invention.

[0092] Figure 1A An electronic device 104 is depicted, such as the electronic device generally discussed above and described in more detail below. The electronic device 104 can include a translucent layer forming an outer surface of a housing of the electronic device 104. A hidden input region can be defined along the outer surface of the housing and used to control the functions of the electronic device 104.

[0093] In a non-limiting example, as Figure 1A shown, the electronic device 104 includes a housing 108. The housing 108 can form an outer surface of the electronic device 104 and define an interior volume. For example, the housing 108 can define sidewalls, a top surface, and a bottom surface of the electronic device 104 that enclose or surround the internal components of the electronic device 104, including the various electrical and structural components described herein.

[0094] The housing 108 can have a translucent layer or be formed in part by a translucent layer. For example, as Figure 1AAs shown, the surface of the housing 108 may be defined or formed by the housing wall 112. In an embodiment, the housing wall 112 may be a light-transmissive layer that permits light to propagate substantially unobstructed between the exterior and interior of the electronic device 104. For example, the housing wall 112 may be formed of a ceramic (e.g., sapphire, emery), glass, plastic, composite, compound, or other suitable translucent, transparent, partially transparent, or in other words light-transmissive structure configured to form the surface of the device housing. In other embodiments, the housing wall 112 may be a metallic component (e.g., Figure 2C the opaque wall 137) that substantially impedes the passage of light. For example, the housing wall 112 may be or form a component of the top shell of a laptop computer, which may be metal, plastic, glass, carbon fiber, ceramic, and / or other materials.

[0095] The outer surface of the housing wall 112 may resemble the outer surface of a device housing that is unmarked and / or has a substantially uniform appearance. Regardless of appearance, in an active state, the electronic device 104 may define an input region 116 along the outer surface of the housing wall 112. The input region 116 may be configured to receive inputs, including touch inputs, force inputs, and / or proximity inputs for controlling the functions of the electronic device 104.

[0096] As described in more detail below, the input region 116 may be a hidden or concealed input region of the electronic device 104. For example, an opaque shielding layer having a micro-perforation array may be positioned along the lower side surface of the housing wall 112. The opaque shielding layer generally may hide the interior of the housing 108, and the micro-perforation array may be visually imperceptible or invisible when not illuminated. When activated, the electronic device 104 reveals the input region 116 by displaying symbols, glyphs, markings, or other notations corresponding to the input region 116 by propagating light through the micro-perforation array. Input components, sensing elements, etc. may be positioned below the input region 116 and configured to trigger switch events in response to touch or force inputs received within the input region 116.

[0097] The electronic device 104 may include various other input / output components that support one or more functions of the electronic device 104. For purposes of illustration, Figure 1A the electronic device 104 is depicted as including a display 120 and keys 124. The electronic device 104 may also include a processing unit (optionally including executable logic and / or a set of computer-readable instructions) for facilitating the operations described herein (e.g., Figure 14processing unit 1408) and / or other hardware or software. It should be noted that the electronic device 104 may also include various other components, such as one or more ports (e.g., charging ports, data transfer ports, etc.), communication elements, additional input / output components (including additional buttons), etc. Thus, the discussion of any electronic device, such as the electronic device 104, is only for illustrative purposes. In Figure 1A In an embodiment, the display 120 may be positioned within a first opening 121 defined by the housing 108, and the keys 124 may be positioned within an array of key openings 125 defined by the housing 108.

[0098] The display 120 may depict a graphical output of the electronic device 104. The graphical output of the display 120 may be modified in a first manner in response to an input received within the input area 116 and may be modified in a second manner in response to a mechanical press received at one or more of the keys 124. For example, the graphical output of the display 120 may be modified to depict a lighted letter or symbol within the input area. In some cases, the letters or symbols depicted on the display 120 may be modified in response to an input at one or more of the keys 124. It should be understood that the electronic device 104 may be any suitable device having a hidden or concealed input area as described herein, including data input devices, word processing devices, desktop computers, laptop computers, smart phones, tablet computers, portable media players, etc. Other examples of electronic devices may include health monitoring devices, digital cameras, printers, scanners, security systems or devices, or electronics for automobiles, buildings, or other structures, as well as other electronic devices.

[0099] The input area 116 may be a hidden or concealed input surface defined on the housing wall 112. The electronic device 104 may define the input area 116 on the housing wall 112 and activate a light source to illuminate symbols indicative of input functions or notifications associated with the input area 116. In this regard, Figures 1B to 1D FIG. depicts a housing wall 112 having an input area 116 in various illuminated states.

[0100] Specifically, Figure 1B FIG. depicts a housing wall 112 having an input area 116 in an unilluminated state. In the unilluminated state, the housing wall 112 may have a substantially uniform appearance that matches or is commensurate with the surrounding portion or area of the electronic device 104. When in the unilluminated state, the electronic device 104 may not respond to an input received within the input area 116 (or other areas of the housing wall 112), so the housing wall 112 may temporarily serve as the outer surface of the housing 108 that does not have an input function.

[0101] In the illuminated state, the electronic device 104 can display the input function of the input area 116 by illuminating or displaying various symbols, notations, etc. within the input area 116. In this regard, Figure 1C depicts a housing wall 112 having an input area 116 in the illuminated state. As Figure 1C shown, the electronic device 104 can display or illuminate a symbol 128 within the input area 116. When in the illuminated state, the electronic device 104 can respond to an input received within the input area 116, so the input area 116 can be used to control the functions of the electronic device 104. In other cases, the symbol 128 can be used to indicate the status or notification of the electronic device 104 and not necessarily for controlling the functions of the electronic device 104. In the present embodiment, the symbol 128 can depict information related to an "email" notification or command. For example, when the electronic device 104 detects an incoming or pending email message, the electronic device 104 can illuminate the symbol 128 within the input area 116; the input area 116 may then receive an input that causes the electronic device 104 to access the email message. However, it should be understood that for illustrative purposes, email-related information depicted by the symbol 128 (and corresponding functions) is shown. As described herein, the symbol 128 can depict any suitable information applicable to a given application, including dynamically adaptable information.

[0102] Figure 1D depicts Figure 1C detail 1-1 of the symbol 128. As Figure 1D a non-limiting example of shown, the symbol 128 can be defined by a pattern that is illuminated by smaller shapes, patterns, features, etc. that jointly define the symbol 128. For example, the envelope of the symbol 128 can be defined by an illuminated pattern 129 that jointly defines the symbol 128.

[0103] As described in more detail below, the illuminated pattern or shape or feature that defines the symbol 128 can be formed based on an opaque masking layer located on the lower side of the housing wall 112. Specifically, the opaque masking layer can define a series of micro-perforations or visually imperceptible holes (when not illuminated) that allow light to pass through the opaque masking layer. In this way, under illuminated conditions, the electronic device 104 can activate a light source disposed within the housing 108 and propagate light through the micro-perforation array. This may cause the symbol 128 to appear within the input area.

[0104] In this regard, Figure 1DThe illuminated pattern 129 depicted may correspond to an array of micro-perforations formed within an opaque shielding layer. For example, each circle or other feature of the illuminated pattern may correspond to a portion of the opaque shielding layer where light is permitted to pass through the opaque shielding layer and propagate toward the outer surface of the housing wall 112. Thus, the array of micro-perforations may be disposed on the opaque shielding layer to form the illuminated pattern 129 of the symbol 128. In other cases, the array of micro-perforations may be arranged in a grid, matrix, or other configuration, and the electronic device 104 may selectively illuminate various subsets of the array of micro-perforations to form the illuminated pattern 129 of the symbol 128 within the input region 116.

[0105] It should be understood that for the purpose of showing an enlarged view of the symbol 128, the illuminated pattern 129 is visible in Figure 1D . Thus, given the relative size of the micro-perforations, when viewed from an appropriate distance, the symbol 128 may appear to be formed of continuous or unbroken lines. For example, as opposed to perceiving the individual micro-perforations that define the symbol 128, a user may perceive the symbol 128 as a substantially solid symbol or a symbol having a collection of solid lines. Since the micro-perforations have dimensions and / or shapes such that the light emitted through the individual micro-perforations blends or mixes with the light emitted by the surrounding micro-perforations, the symbol 128 may appear solid when viewed from a distance. This effect of the micro-perforations (forming a solid or continuous symbol from discrete openings when illuminated from within the electronic device 104) is particularly observable when a user views the input region 116 from a distance of several inches to several feet, which may correspond to an appropriate viewing distance for observing and / or interacting with the electronic device 104.

[0106] Figure 2A is depicted Figure 1A of a functional cross-sectional view of the input region 116. Figure 2A The input region 116 is shown in an unactuated configuration, e.g., where the input region 116 is not receiving an input.

[0107] Generally speaking, the input region 116 includes various components that allow the electronic device 104 to conceal or hide the input region 116 on the housing 108 and use the input region 116 to display illuminated symbols as well as control the functions of the electronic device 104. As Figure 2AAs shown, the input region 116 can be associated with a cross-section or region of the electronic device 104 that includes the housing wall 112, the opaque shielding layer 132, the light source 136, the haptic structure 140, and the sensing element 144. The opaque shielding layer 132 can define a micro-perforation array 134 that extends through the opaque shielding layer 132 and defines or forms symbols, glyphs, or other markings. The light source 136, the haptic structure 140, and the sensing element 144 can together form an input assembly 148 that can be used to define illuminated symbols on the housing wall 112 using the micro-perforation array 134 to detect inputs within the input region 116. The input assembly 148 can be positioned within the internal volume 109 of the housing 108.

[0108] The housing wall 112 can define the outer surface 113 of the electronic device 104. The housing wall 112 can extend into and through the thickness of the housing 108 and have a lower surface 114 positioned within the housing 108 (such as within the internal volume 109). This can allow light to pass through the housing 108 between the exterior and interior of the electronic device 104 substantially unobstructed. The housing wall 112 can be configured to receive inputs, including touch-based or proximity-based inputs and / or force inputs. In this way, the housing wall 112 can exhibit one or more material properties that allow the housing wall 112 to bend, deflect, deform, etc. in response to a force input received within the input region 116. The housing wall 112 can be a multi-layer structure that can include one or both of a translucent layer and / or a metallic layer. The housing wall 112 can also define various textured surfaces that can be positioned along the exterior of the electronic device and have various light dispersion properties. For example, when the housing 112 is a translucent layer, the housing wall 112 can have a textured surface at or near the input region 116 that directs light emitted from within the electronic device 104 in a specific direction. As described below, the input assembly 148 can use such material properties of the housing wall 112 to detect a force input received within the input region 116.

[0109] The opaque shielding layer 132 can be positioned along the lower surface 114 of the housing wall 112. In some cases, the opaque shielding layer 132 can be formed directly on the lower surface 114, for example, by printing, deposition, sputtering, plating, or other suitable processes. In other cases, the opaque shielding layer 132 can be a separate substrate, film, or other layer applied to the lower surface 114 or applied to an intermediate PET layer attached to the lower surface 114 (e.g., as described below with reference to Figure 2DAs described in more detail). The opaque shielding layer 132 can be ink, a coating, a resin, or other structures that substantially block the passage of light. The opaque shielding layer 132 can have sufficient flexibility or ductility to be bent repeatedly without cracking, breaking, or otherwise being damaged. Thus, when applied to the lower surface 114, the opaque shielding layer 132 can prevent light from traveling between the exterior and interior of the electronic device 104.

[0110] Although the opaque shielding layer 132 substantially blocks the passage of light, a micro-perforation array 134 defined within the opaque shielding layer 132 can allow light to pass through the opaque shielding layer 132. The micro-perforation array 134 can be openings, holes, through-parts, cuts, grooves, recesses, or other feature structures that extend through the entire thickness of the opaque shielding layer 132. In this regard, the micro-perforation array 134 can allow light to pass through the opaque shielding layer 132 and then through the housing wall 112. As described herein, the micro-perforation array 134 can define or can be used to define a symbol on the outer surface 113. For example, the electronic device 104 can use a light source 136 to illuminate the interior volume 109 and thereby cause the housing wall 112 to display a symbol corresponding to the illuminated micro-perforation array 134 within the input region 116.

[0111] At the outer surface 113, when not illuminated, the micro-perforation array 134 may be substantially visually imperceptible. For example, the micro-perforation array 134 can have dimensions, shapes, or other characteristics such that the micro-perforation array 134 is invisible or visually imperceptible to the human eye. This can allow the micro-perforation array 134 to be hidden from the user by a translucent layer, the housing wall, etc. when not illuminated. In one embodiment, the micro-perforation array 134 can have a width or other lateral dimension in the range of 30 micrometers to 80 micrometers. For example, the micro-perforation array 134 can be defined by a circle pattern, with each circle having a diameter in the range of 30 micrometers to 80 micrometers. The micro-perforation array 134 can be arranged on the opaque shielding layer 132 such that each perforation is spaced a distance in the range of 80 micrometers to 500 micrometers. For example, in the case where each micro-perforation is defined by a circle, each circle can be spaced a distance in the range of 80 micrometers to 500 micrometers on the opaque shielding layer 132. It should be understood that other dimensions and geometries are contemplated and will be described in more detail below, including configurations where the width of each micro-perforation is less than 30 micrometers or greater than 80 micrometers, including widths of 130 micrometers or greater, and where the spacing distance is less than 80 micrometers or greater than 500 micrometers. Additionally, each micro-perforation of the micro-perforation array 134 need not have the same or consistent width or spacing; in some cases, various subsets of the micro-perforation array 134 can have different widths or spacings, which can be used to produce desired optical effects and for other considerations.

[0112] Below the opaque shielding layer 132 is the input assembly 148. As described above, the input assembly 148 includes a light source 136, a haptic structure 140, and a sensing element 144. The light source 136, the haptic structure 140, and the sensing element 144 can be arranged in the internal volume 109 in any suitable configuration to illuminate symbols on the outer surface 113 of the housing wall 112, detect inputs within the input area 116, and generate corresponding haptic or tactile outputs. This can allow the input assembly 148 to control one or more functions of the electronic device 104. In some cases, the input assembly 148 may include fewer or more components that are necessary for a given application. For example, in a configuration where the input area 116 is used to provide notifications without input and / or haptic functionality, the input assembly 148 may include the light source 136.

[0113] As described below with reference to Figures 7A to 7C As described in more detail below, the light source 136 can be any suitable component that emits light. Specifically, the light source 136 can be any suitable component that passes light through the micro-perforation array 134 and propagates the light towards the outer surface 113. As described herein, example light sources include LEDs, micro-LEDs, and / or light guides. However, other light sources 136 can also be used.

[0114] As described below with reference to Figures 9A to 9J As described in more detail below, the haptic structure 140 can be any suitable structural component that generates a haptic or tactile output. Specifically, the haptic structure 140 can be any suitable component that conveys movement or vibration along the outer surface 113 that is perceivable by human touch. In response to an input received within the input area 116, the electronic device 104 can use the haptic structure 140 to convey a haptic or tactile output. For example, the haptic structure 140 can be a mechanical structure, such as a retractable tab, a spring, etc., that generates movement or vibration in response to a force input received within the input area 116. In other cases, the haptic structure 140 can be an electro-activated component that conveys a haptic or tactile output in response to a touch and / or force input detected by the sensing element 144. For example, the haptic structure 140 can be an electromagnet, an electro-active polymer, or a piezoelectric (EAP) stack, etc. In an embodiment, for example, the haptic structure 140 can be at least partially included within the sensing element 144 or directly coupled to the sensing element 144, such as when the haptic structure 140 is the retractable tab of a haptic membrane switch that is used to detect a force input received within the input area 116.

[0115] As described below with reference to Figures 9A to 9JAs described in more detail, the sensing element 144 can be any suitable component that detects touch and / or force inputs received within the input area 116. In this regard, the sensing element 144 can be a variety of components, sensors, assemblies, etc. positioned below and / or coupled to the housing wall 112. In one embodiment, the sensing element 144 can be a non-contact sensing element that detects touch and / or force inputs. This can include capacitive or magnetic-based sensors configured to detect the proximity of the user 150 to the housing wall 112 (including contact between the user 150 and the outer surface 113). The non-contact sensing element can also detect local or global bending or deflection of the housing wall 112, which can be used to determine corresponding force inputs associated with the deflection. In addition or alternatively, the sensing element 144 can be a contact sensor, such as a tactile dome switch, that detects force inputs on the outer surface 113 in response to local or global bending or deflection of the housing wall 112.

[0116] It should be understood that, for purposes of illustration, Figure 2A a functional cross-sectional view of the input assembly 148 is shown. In the various embodiments described herein, the input assembly 148 can include a plurality of different sensing elements and / or tactile structures that can be coupled to each other to produce a desired effect. For example, the sensing element 144 and the tactile structure 140 can each include a plurality of different structures, such as one or more of the different sensing and / or tactile structures described with reference to Figures 9A to 9J as described. Thus, the sensing elements and / or tactile structures described with reference to Figures 9A to 9J can be used or grouped in any suitable combination (including used independently) to form the input assembly 148 described with reference to Figure 2A as described.

[0117] Figure 2B depicts Figure 1A a functional cross-sectional view of the input area 116 of Figure 2A The input area 116 is shown in an actuated configuration, e.g., where the input area 116 receives an input from the user 150. As described herein, the housing wall 112 can be configured to deform locally or globally in response to a force input. This may not be perceptible haptically. Additionally, the bending or deformation of the housing wall 112 can be elastic such that the housing wall 112 substantially returns to its undeformed shape when the force ceases.

[0118] As Figure 2BAs shown, when the user 150 applies a force input to the outer surface 113, the housing wall 112 may bend. The opaque shielding layer 132 positioned on the lower surface 114 may also bend. Thus, the opaque shielding layer 132 can be flexible and / or elastic relative to the deformation or repeated bending of the housing wall 112. In this way, the opaque shielding layer 132 does not break, shatter, or in other words get damaged when the housing wall 112 bends. The input assembly 148 can detect the bending of the housing wall 112 to estimate the force input received within the input region 116 and / or determine one or more characteristics of the force input, such as magnitude. As one possibility, the sensing element 144 can measure a change in the gap between the opaque shielding layer 132 and another structure or component within the internal volume 109 to detect the force input. For example, a capacitive sensor can measure a change in capacitance between electrodes positioned around the gap and determine the force input associated with the change. In another embodiment, the conductive contact elements of a contact switch can be positioned beneath the housing wall 112 and configured to contact each other in response to an input received within the input region 116, thereby triggering a switch event. Other techniques for detecting a force input associated with the bending of the housing wall 112 are envisioned and are described herein with reference to Figures 9A to 9J are described.

[0119] Figure 2C depicts Figure 1A a functional cross-sectional view of an alternative embodiment of the input region 116. Figure 2C shows the input region 116 in an unactuated configuration, e.g., where the input region 116 is not receiving an input.

[0120] In Figure 2C the embodiment of, the input region 116 can be associated with a cross-section or region of the electronic device 104 that includes an opaque wall 117, a micro-perforation array 134, a light source 136, a haptic structure 140, and a sensing element 144. The opaque wall 117 can define the outer surface 113 of the electronic device 104. For example, the housing wall 112 can be a metal layer that forms part of the housing wall (e.g., Figure 1A the housing wall 112 of). The opaque wall 177 can be formed of a metal material, plastic, ceramic, composite, synthetic, or other component that substantially blocks light from entering the internal volume of the housing 109.

[0121] As Figure 2CAs shown, the micro-perforation array 134 can be defined by the opaque wall 117 and allows light to pass between the interior and exterior of the electronic device 104. For example, the micro-perforation array 134 can be holes, openings, through-parts, etc. that extend through the entire thickness of the opaque wall 117. The micro-perforation array 134 can be configured to be visually imperceptible on the opaque wall 117 when not illuminated. For example, when illuminated by the light source 136, the micro-perforation array 134 can define or form an illuminated symbol within the input area 116.

[0122] Figure 2D depicts Figure 1A A functional cross-sectional view of an alternative embodiment of the input area 116. Figure 2C Shows the input area 116 in an unactuated configuration, e.g., where the input area 116 is not receiving an input.

[0123] In Figure 2D an embodiment, the input area 116 can be associated with a cross-section or region of the electronic device 104 that includes one or more intermediate layers. For example, as Figure 2D shown, the electronic device 104 can include intermediate layers 115a, 115b. The intermediate layer 115a can be positioned between the housing wall 112 and the opaque shielding layer 132. The intermediate layer 115b can be positioned between the opaque shielding layer 132 and the input assembly 148. The intermediate layers 115a, 115b can provide a moisture barrier or other transition layer between one or more components of the electronic device 104. The PET layers 115a, 115b can be semi-transparent (e.g., transparent, partially transparent, or in other words capable of transmitting light). This can allow the light generated by the light source 136 to propagate through the micro-perforation array 134 and define a symbol within the input area 116 on the housing wall 112. The intermediate layers 115a, 115b can be formed of or include polyethylene terephthalate (PET), silicon, glass sheets, ceramic sheets, etc. However, other materials are possible, including plastics, composites, compounds, etc.

[0124] Figures 3A to 3C depicts the housing wall 112 having the input area 116 in various illuminated configurations or modes. The input area 116 can be used to control a variety of different functions of the electronic device 104 and / or display or convey various different indications or notifications associated with the electronic device 104. In this regard, the electronic device 104 can be configured to illuminate a plurality of different symbols within the input area 116. For example, as described above with reference to Figure 2A the light source 136 can illuminate various subsets of the micro-perforation array 134 that correspond to or form various different symbols. For illustrative purposes only, reference Figures 3A to 3CShows a micro-perforation array 134 and is not intended to convey scale. Instead, the micro-perforation array 134 is depicted in Figures 3A to 3C to illustrate the principles described herein.

[0125] The illuminated symbol may correspond to the function of the input region 116. For example, and as described in more detail below with reference to Figure 10A FIG. 13, the processing unit may be located within the housing 108 (or alternatively operatively coupled to the electronic device 104) and configured to define the input region 116 on the housing wall 112. The processing unit may also be configured to associate the input region 116 with specific functions of the electronic device 104, including alphanumeric commands, media playback commands, power commands, and other possibilities. Thus, the input assembly 148 may be operatively coupled to the processing unit and configured to selectively illuminate the micro-perforation array 134 such that the light source 136 illuminates a subset of the micro-perforation array 134 that together forms a symbol corresponding to the function of the input region 116. When viewed from an appropriate distance, the individual micro-perforations in the micro-perforation array 134 may not be distinguishable from one another, and thus the illuminated symbol may appear solid or uniform. Substantially similarly, when the translucent region receives an input, the input assembly 148 may trigger a switching event and / or generate a haptic output corresponding to the function of the input region 116.

[0126] Referring to Figure 3A , in the first mode, the housing wall 112 may include a symbol 128a in the input region 116. The symbol 128a may be a first illuminated symbol formed or defined by a first subset of the micro-perforation array 134. Thus, the light source 136 may illuminate the first subset of the micro-perforation array 134 to display the symbol 128a within the input region 116. The symbol 128a may indicate that the input region 116 is available for providing an input associated with the letter "A" to the electronic device 104. The processing unit coupled to the input region 116 may generate a first input signal or a first switching event in response to detecting the input, and the first input signal or the first switching event may be used to control the function of the electronic device 104 associated with the symbol 128a. In this regard, when the symbol 128a is illuminated, the graphical output of the display (e.g., Figure 1A the display 120) of the electronic device 104 may be modified in a first manner in response to an input received within the input region 116. A haptic output may be provided to the input region 116 when an input corresponding to the symbol 128a is received. In some cases, the symbol 128a may also provide a notification to the user 150 associated with the state of the electronic device 104.

[0127] Referring to Figure 3B, in the second mode, the housing wall 112 may include a symbol 128b in the input area 116'. The symbol 128b may be a second illuminated symbol formed or defined by a second subset of the micro-perforation array 134. Thus, the light source 136 may illuminate the second subset of the micro-perforation array 134 to display the symbol 128b in the input area 116. The symbol 128b may indicate that the input area 116' is available for providing an input associated with the power button to the electronic device 104. The processing unit coupled to the input area 116' may generate a second input signal or a second switching event in response to detecting the input, and the second input signal or the second switching event may be used to control a function of the electronic device 104 associated with the symbol 128b. In this regard, when the symbol 128b is illuminated, in response to an input received in the input area 116', the graphical output of the display of the electronic device 104 (e.g., Figure 1A the display 120) may be modified in a second manner. A haptic output may be provided to the input area 116' when an input corresponding to the symbol 128b is received. In some cases, the symbol 128b may also provide a notification associated with the state of the electronic device 104 to the user 150.

[0128] Reference Figure 3C , in the third mode, the housing wall 112 may include a symbol 128c in the input area 116". The symbol 128c may be a third illuminated symbol formed or defined by a third subset of the micro-perforation array 134. Thus, the light source 136 may illuminate the third subset of the micro-perforation array 134 to display the symbol 128c in the input area 116". The symbol 128c may indicate that the input area 116" is available for providing an input associated with the media playback function to the electronic device 104. The processing unit coupled to the input area 116" may generate a third input signal or a third switching event in response to detecting the input, and the third input signal or the third switching event may be used to control a function of the electronic device 104 associated with the symbol 128c. In this regard, when the symbol 128c is illuminated, in response to an input received in the input area 116", the graphical output of the display of the electronic device 104 (e.g., Figure 1A the display 120) may be modified in a third manner. A haptic output may be provided to the input area 116" when an input corresponding to the symbol 128c is received. In some cases, the symbol 128c may also provide a notification associated with the state of the electronic device 104 to the user 150.

[0129] It should be understood that the symbols 128a, 128b, 128c may define the boundaries of the respective input regions within the input regions 116, 116', 116". In this regard, the symbols 128a, 128b, 128c may define modified boundaries of the input regions 116, 116', 116" based on the size, shape, and / or other characteristics of the particular illuminated symbol. For example, each of the symbols 128a, 128b, 128c may be defined by a different size and / or have a different illuminable surface area. Thus, the size of the input regions 116, 116', 116" may be adjusted and these input regions modified based on the illumination of a particular symbol among the symbols 128a, 128b, 128c within the input region 116. By way of illustration, the symbol 128a may define the boundary of the input region 116, the symbol 128b may define a modified boundary of the input region 116', and the symbol 128c may define a second modified boundary of the input region 116". In this way, when the symbol 128a is illuminated, the sensing element 140 described with reference to Figure 2A may respond to an input received within the boundary of the input region 116; when the symbol 128b is illuminated, it may respond to an input received within the modified boundary of the input region 116'; and / or when the symbol 128c is illuminated, it may respond to an input received within the second modified boundary of the input region 116". This may facilitate the use of the input regions 116, 116', 116" as a dynamic input surface for controlling various functions of the electronic device 104.

[0130] Figures 3A to 3C The symbols 128a, 128b, 128c depicted are shown to illustrate the formation of the symbols 128a, 128b, 128c using the micro-perforation array 134. As described above, the micro-perforation array 134 may be visually imperceptible when not illuminated. Thus, given the relative size of the micro-perforations, the symbols 128a, 128b, 128c may appear to be formed by continuous or unbroken lines when viewed from an appropriate distance.

[0131] Figure 4 A cross-sectional view of the input region 116 taken along the line A-A of Figure 1A is depicted. As Figure 1A shown, light may propagate along the optical path L1 and define a symbol within the input region 116. The input region 116 may control the functions of the electronic device 104 in response to an input. For clarity, some elements associated with the input region 116 are omitted in Figure 4 Figure 4 Figure 4 .

[0132] As described above, the housing wall 112 can form the outer surface of the electronic device 104, such as the outer surface 113. The housing wall 112 can be positioned over the interior volume 109 of the electronic device 104 and at least partially define the interior volume 109 of the electronic device 104. The interior volume 109 can include a support structure 110. The support structure 110 can be a post, beam, pedestal, pile, or other similar structure for supporting one or more components within the housing 108. As Figure 4 shown, the support structure 110 can be configured to support or hold the position of the housing wall 112. The support structure 110 can also define a section of the interior volume 109 where the housing wall 112 can bend in response to a force. For example, the housing wall 112 can extend between two support structures 110 and bend into the section of the interior volume 109 in response to a force input.

[0133] An optical path L1 can emanate from within the interior volume 109 and travel toward the outer surface 113 to illuminate a symbol within the input area 116. A light source ( Figure 4 not shown) can be positioned within the interior volume 109 and emit light generally along the optical path L1 toward the opaque shielding layer 132. The opaque shielding layer 132 can generally block light. However, a micro-perforation array 134 defined by the opaque shielding layer 132 can allow light to pass through and reach the position of the overlying housing wall 112. Accordingly, the optical path L1 can extend through some or all of the micro-perforation array 134 and into the housing wall 112. The optical path L1 can continue through the housing wall 112 generally in a direction corresponding to the direction in which the optical path L1 passed through the micro-perforation array 134. Thus, the optical path L1 can reach the outer surface 113 and form an appearance of an illuminated symbol within the input area 116 corresponding to the configuration or arrangement of the illuminated micro-perforation array 134.

[0134] Figures 5A to 5F Various configurations of the opaque shielding layer 132 are depicted. Specifically, Figures 5A to 5F various configurations, arrangements, shapes, sizes, patterns, etc. of the micro-perforations defined by the opaque shielding layer 132 are depicted. The micro-perforations can generally be visually imperceptible holes, openings, or through-parts that extend through the full thickness of the opaque shielding layer 132. The micro-perforations can be defined by curved edges formed within the opaque shielding layer 132. Light can pass through the opaque shielding layer 132 at the micro-perforations. In some cases, the shape, size, dimensions, or other physical properties of the micro-perforations can be tuned or modified to control the optical characteristics of the illuminated symbol defined within the input area 116, as described in more detail below.

[0135] Reference Figure 5A, the opaque shielding layer 132 is shown as defining a micro-perforation array 134a within the input area 116. The micro-perforation array 134a may be arranged in a grid or matrix pattern on the input area 116. The micro-perforation array 134a may include micro-perforations 135a. The micro-perforations 135a may be substantially circular openings extending through the thickness of the opaque shielding layer 132. Some or all of the micro-perforation array 134a may be illuminated to display one or more symbols within the input area 116.

[0136] Figure 5B depicts Figure 5A Detail 2-2 of the micro-perforation array 134a. As Figure 5B shown by way of non-limiting example, the micro-perforation 135a may have a width 137. The width 137 may be the lateral dimension of the micro-perforation 135a. The width 137 may be in the range of 30 micrometers to 80 micrometers, such as in the range of 10 to 30 micrometers or in the range of 80 to 100 micrometers. In some cases, the width 137 may be less than 10 micrometers or greater than 100 micrometers. For example, the width 137 may be 130 micrometers or greater. In either case, the micro-perforations may not be visually perceptible to the user. Thus, when not illuminated, the micro-perforations may be hidden, masked, concealed, etc., such as being hidden beneath the outer surface of the device. As described herein, this may allow the input function of the device to be hidden when the device is turned off.

[0137] The micro-perforations 135a may also be separated from other micro-perforations within the micro-perforation array 134a by a spacing 138. The spacing 138 may indicate the density or resolution of the micro-perforation array 134a. The spacing 138 may be in the range of 80 micrometers to 500 micrometers. In some cases, the spacing 138 may be less than 80 micrometers or greater than 500 micrometers, such as in the range of 50 micrometers to 80 micrometers or 500 micrometers to 600 micrometers.

[0138] When the electronic device 104 is in an unilluminated configuration, the width 137 and the spacing 138 may be configured to hide the input area 116. The micro-perforation array 134a may be formed on the opaque shielding layer 132 such that the width 137 and the spacing 138 render the micro-perforation array 134a invisible to the human eye along the outer surface 113 of the housing wall 112. The width 137 and the spacing 138 may also be selected to alter the optical characteristics of the illuminated symbols. For example, the width 137 and / or the spacing 138 may be used to control one or more of the clarity, contrast, brightness, color, optimal viewing angle, or other associated properties of the illuminated symbols within the input area 116. For example, as the width 137 increases, the illuminated symbols may appear brighter, while as the spacing 138 decreases, the clarity of the lines formed by the illuminated symbols may increase.

[0139] Referring to Figure 5C, the opaque shielding layer 132 is shown as defining a micro-perforation array 134b within the input area 116. The micro-perforation array 134b can be arranged on the input area 116 to form a diamond-shaped grid or matrix pattern. For example, the micro-perforation array 134b can be arranged as a diamond grid on the opaque shielding layer 132. The micro-perforation array 134b can include micro-perforations 135b. The micro-perforations 135b can be substantially circular openings extending through the thickness of the opaque shielding layer 132. Some or all of the micro-perforation array 134b can be illuminated to display one or more symbols within the input area 116.

[0140] Reference Figure 5D , the opaque shielding layer 132 is shown as defining a micro-perforation array 134c within the input area 116. The micro-perforation array 134c can be arranged on the input area 116 in a circular pattern. Specifically, the micro-perforation array 134c can be defined as an "offset-in" pattern, where the micro-perforation array 134c is arranged inward from the outermost ring of the micro-perforation array 134c. The micro-perforation array 134c can include micro-perforations 135c. The micro-perforations 135c can be substantially circular openings extending through the thickness of the opaque shielding layer 132. Some or all of the micro-perforation array 134c can be illuminated to display one or more symbols within the input area 116.

[0141] Reference Figure 5E , the opaque shielding layer 132 is shown as defining a micro-perforation array 134d within the input area 116. The micro-perforation array 134d can be arranged on the input area 116 in a grid or matrix pattern. The micro-perforation array 134d can include micro-perforations 135d. The micro-perforations 135d can be substantially curved or wavy semi-circular or arched openings extending through the thickness of the opaque shielding layer 132. Some or all of the micro-perforation array 134d can be illuminated to display one or more symbols within the input area 116.

[0142] Reference Figure 5F , the opaque shielding layer 132 is shown as defining a micro-perforation array 134e within the input area 116. The micro-perforation array 134e can be arranged on the input area 116 in a cross-hatch pattern. The micro-perforation array 134e can include micro-perforations 135e. The micro-perforations 135e can be substantially elongated openings arranged vertically or horizontally on the opaque shielding layer 132 and extending through the thickness of the opaque shielding layer 132. Some or all of the micro-perforation array 134e can be illuminated to display one or more symbols within the input area 116.

[0143] Figures 6A to 6B Depicts various configurations of the opaque shielding layer 132. The thickness of the opaque shielding layer 132 can extend into the internal volume 109. The micro-perforation arrays (such as those referenced above Figures 1A to 5FThe microperforation array 134 described may be an opening or through-portion extending through the thickness of the opaque obscuring layer 132. In some cases, for example, the microperforation array 134 may have a non-uniform cross-section throughout the thickness of the opaque obscuring layer 132, such that a portion of the sidewall defined by a given microperforation may be angled, tapered, chamfered, etc. relative to the lower surface 114 of the housing wall 112. The non-uniform or variable cross-section of the microperforation array 134 may affect the optical properties of a symbol or other indicia illuminated on the exterior surface 113, which may also help define a particular viewing angle or cone of view relative to the housing wall 112, for example by helping to direct light within the cone of view.

[0144] refer to Figure 6A , showing the Figure 1A The line AA intercepts Figure 1A 1. A cross-sectional view of the input region 116 of FIG. 1. As shown, the opaque shielding layer 132 may include or define a microperforation array 634a. The microperforation array 634a may extend through the full thickness of the opaque shielding layer 132 and may allow light to pass from the interior volume 109 to the outer surface 113 of the input region 116.

[0145] The microperforation array 634a may have a non-uniform cross-section along the thickness of the opaque obscuring layer 132. For example, each of the microperforation array 634a may have an angled or tapered sidewall that extends through the thickness of the opaque obscuring layer 132. In a particular embodiment, the cross-section of the microperforation array 134a at the interior volume 109 may be larger than the cross-section at the lower surface 114. This may allow the opaque obscuring layer 132 to focus light onto the outer surface 113 and / or selectively direct light to the outer surface.

[0146] refer to Figure 6B , showing the Figure 1A The line AA intercepts Figure 1A 1. As shown, the opaque shielding layer 132 may include or define a microperforation array 634b. The microperforation array 634b may extend through the full thickness of the opaque shielding layer 132 and may allow light to pass from the interior volume 109 to the outer surface 113 of the input region 116.

[0147] The microperforation array 634b may have a tapered or angled cross-section along the thickness of the opaque shielding layer 132. For example, each of the microperforation array 634b may extend through the opaque shielding layer 132 at an angle. This may allow the opaque shielding layer 132 to focus light onto the outer surface 113 and / or selectively direct light to the outer surface. In a specific embodiment, the microperforation array 634b may be used to reduce the viewing angle or cone of view. For example, the microperforation array 634b may focus light emitted from the interior volume in a narrow or restricted manner.

[0148] Figures 7A to 7C depicts various configurations of a light source, such as the light source 136 described above with reference to Figure 2A and Figure 2B . Specifically, Figures 7A to 7C depicts example components and configurations for passing light through the micro-perforation array 134 and causing a symbol or other indicia to be illuminated at the input region 116. It should be understood that the following components associated with or forming the light source are shown for illustrative purposes only. Other components configured to pass light through the micro-perforation array 134 are contemplated in the present disclosure.

[0149] Referring to Figure 7A , a cross-sectional view of the input region 116 of Figure 1A taken along line A-A of Figure 1A is shown. As shown, the electronic device 104 includes a light source 136a positioned below the housing wall 112 and within the internal volume 109. The light source 136a may operate in a manner substantially similar to the light source 136 described above with reference to Figure 2A and Figure 2B . For example, the light source 136a may be configured to propagate light along an optical path L1 that extends from within the internal volume 109 through the micro-perforation array 134 and toward the outer surface 113 to define a symbol or glyph within the input region 116.

[0150] In Figure 7A embodiments, the light source 136a may be a light-emitting diode (LED). The light source 136a may project or generate light from a single location within the internal volume 109. This may illuminate all or substantially all of the micro-perforation array 134.

[0151] Referring to Figure 7B , a cross-sectional view of the input region 116 of Figure 1A taken along line A-A of Figure 1A is shown. As shown, the electronic device 104 includes a light source 136b positioned below the housing wall 112. The light source 136b may operate in a manner substantially similar to the light source 136 described above with reference to Figure 2A and Figure 2B . For example, the light source 136b may be configured to propagate light along an optical path L1 that extends through the micro-perforation array 134 and toward the outer surface 113 to define a symbol or glyph within the input region 116.

[0152] In Figure 7BIn an embodiment, the light source 136b may be a micro-LED array. The micro-LED array may be positioned on the thin film 151 and arranged relative to the micro-perforation array 134. For example, in one embodiment, the micro-LEDs of the micro-LED array may be positioned within corresponding micro-perforations in the micro-perforation array 134. Additionally or alternatively, the micro-LEDs of the micro-LED array may be positioned below or near a particular group of micro-perforations. The micro-LEDs of the micro-LED array may be selectively actuated to illuminate particular micro-perforations or groups of micro-perforations in the micro-perforation array 134. This may allow the electronic device 104 to display multiple different symbols or glyphs within the input area 116 and subsequently use the input area 116 to control various functions of the electronic device 104.

[0153] Reference Figure 7C , shows a cross-sectional view of the input area 116 taken along line A-A of Figure 1A . As shown, the electronic device 104 includes a light source 136c positioned below the housing wall 112 and within the internal volume 109. The light source 136c may operate in a manner substantially similar to the light source 136 described above with reference to Figure 1A and Figure 2A . For example, the light source 136c may be configured to propagate light along an optical path L1 that extends from within the internal volume 109 through the micro-perforation array 134 and toward the outer surface 113 to define a symbol or glyph within the input area 116. Figure 2B

[0154] In an Figure 7C embodiment, the light source 136c may be an optical waveguide. The optical waveguide may guide light through the internal volume 109. For example, the optical waveguide may be coupled to a light-emitting element (such as the light-emitting element 139) within the internal volume 109 and guide light from the light-emitting element to the input area 116. The optical waveguide may define one or more light extraction features that may direct light toward one or more of the micro-perforations in the micro-perforation array and thereby out of the optical waveguide. Accordingly, the optical waveguide may illuminate the micro-perforation array in various configurations.

[0155] Figure 8A and Figure 8BDepicts various optical characteristics of symbols, glyphs, or other markings illuminated on the housing wall 112. As described herein, the electronic device 104 can be configured to illuminate one or more symbols on the housing wall 112, and the one or more symbols can indicate functions, notifications, etc. of the electronic device 104. For example, a light source positioned below the housing wall 112 can propagate light from inside the electronic device 104 and through a micro-perforation array defined in an opaque shielding layer along the lower side of the housing wall 112, such that the housing wall 112 displays the illuminated symbols. The opaque shielding layer 132 and / or the light source can be configured such that the illuminated symbols on the housing wall 112 exhibit various optical characteristics, including specified clarity, contrast, brightness, color, optical viewing angle, etc.

[0156] Reference Figure 8A , shows the housing wall 112. Positioned below the housing wall 112 is an opaque shielding layer 132 (not shown), which defines a micro-perforation array 134 (shown in dashed lines). Light can propagate through the micro-perforation array 134 to display illuminated symbols on the housing wall 112. As Figure 8A shown, the housing wall 112 can include an illuminated symbol 828.

[0157] At different viewing angles, the illuminated symbol 828 can exhibit various optical characteristics at the housing wall 112. For example, the optical characteristics of the illuminated symbol 828 at an angle θ1 can be different from the optical characteristics of the illuminated symbol 828 at an angle θ2. For illustration, when observed at θ1, the illuminated symbol can have a first brightness, clarity, contrast, etc., while when observed at θ2, the illuminated symbol can have a second brightness, clarity, contrast, etc. This can be at least partially affected by the micro-perforation array located below the housing wall 112. For example, the micro-perforation array 134 can have dimensions, shapes, spacings, or other characteristics such that the illuminated symbol 828 has different optical characteristics at angles θ1, θ2. In addition or alternatively, light can propagate through the micro-perforation array 134 to produce different optical characteristics.

[0158] In some cases, the micro-perforation array 134 can be used to define a viewing cone. For example, the micro-perforation array 134 can cause the illuminated symbol 828 to exhibit optical characteristics such that the illuminated symbol 828 is visible within a specified region of three-dimensional space. In this regard, the viewing cone can extend from the illuminated symbol 828 and represents the region of three-dimensional space in which the symbol 828 is visible. As Figure 8AAs shown, each depicted viewing or incident angle θ1, θ2 can be separated from one another by a radial spacing φ. The radial spacing φ can define the boundaries of the viewing cone. In this way, the electronic device 104 can display the illuminated symbol 828 on the housing wall 112 in such a manner that it is visible within the radial spacing φ but not visible or, in other words, obscured outside of the viewing cone. In this regard, more generally, by having different optical characteristics at different viewing angles, the electronic device 104 can be configured to display the illuminated symbol on the housing wall 112 in such a way that it is visible to the user but not visible, obscured, or, in other words, unidentifiable to onlookers or other persons in the vicinity of the electronic device 104.

[0159] Reference Figure 8B , the housing wall 112 is shown. Located below the housing wall 112 is an opaque shielding layer 132 (not shown), which defines a micro-perforation array 134 (shown in dashed lines). Light can propagate through the micro-perforation array 134 to display the illuminated symbol on the housing wall 112. As Figure 8B shown, the housing wall 112 can include illuminated symbols 828a and 828b.

[0160] The electronic device 104 can be configured to propagate light along different optical paths through specific micro-perforations or groups of micro-perforations in the micro-perforation array 134. The light traveling on different optical paths can interfere constructively or destructively with one another and produce various optical effects, such as optical diffraction. For example, the illuminated symbol 828a can be illuminated by light traveling along the optical path L1, while the illuminated symbol 828b can be illuminated by light traveling along the optical path L2. For example, the optical paths L1, L2 can be calibrated to interfere with one another such that the light from each of the optical paths L1, L2 combines or cooperates to form a new optical path and a corresponding light wave. When viewed from an appropriate distance, the new optical path can exhibit a desired optical effect, including a desired contrast, brightness, and / or color.

[0161] The interference of the light propagating along the optical paths L1, L2 can be affected at least in part by the micro-perforation array 134 located below the housing wall 112. For example, the micro-perforation array 134 can have various different sizes, shapes, spacings, etc. such that light propagates through the micro-perforation array 134 along different optical paths. In addition or alternatively, light can be directed to specific micro-perforations in the micro-perforation array 134 in order to cause the light to travel along different optical paths. By creating an interference pattern between different optical paths, the electronic device 104 can be configured to display an illuminated symbol on the housing wall 112 that has a unique effect specific to the resulting interference optical path or light wave.

[0162] Figures 9A to 9J Depicts a cross-sectional view of the input region 116 taken along Figure 1A the line A-A of Figure 1A . Specifically, Figures 9A to 9JDepicts various sensing elements and haptic structures positioned below the housing wall 112. The sensing elements and haptic structures can be sensing elements and / or haptic structures configured to detect inputs received within the input area 116 and / or deliver haptic outputs, such as the haptic structure 140 and sensing element 144 described above with reference to Figures 2A to 2D As such, the sensing elements and haptic structures described with reference to Figures 9A to 9J can be, form, or include one or more of the haptic structure 140 and / or sensing element 144 described above with reference to Figures 2A to 2D It should be understood that, for illustrative purposes only, the sensing elements and haptic structures shown and described with reference to Figures 9A to 9J are shown; the electronic device 104 can include a variety of different combinations of the sensing elements and haptic structures described herein, including other sensing elements and haptic structures suitable for a given application configured to detect inputs within the input area 116 and / or deliver haptic outputs. As described below, at least some portions or segments of the sensing elements and haptic structures described with reference to Figures 9A to 9J can be translucent or, in other words, capable of allowing some light to pass through. In this regard, the sensing elements and haptic structures can support or, in other words, allow light from the light sources described herein to reach the outer surface 113 and display illuminated symbols or glyphs within the input area 116.

[0163] With reference to Figure 9A , the electronic device 104 is shown as having a haptic dome 942a. The haptic dome 942a can be configured to bend in response to an applied force. The haptic dome 942a can be positioned within the internal volume 109 below the housing wall 112 and the opaque shielding layer 132. In some cases, the top surface of the haptic dome 942a can contact or abut the opaque shielding layer 132, and in other cases, the opaque shielding layer 132 and the haptic dome 942a can be separated by a gap. The housing wall 112 can receive a force input that causes the housing wall 112 to bend or deform within the input area 116. This bending or deformation of the housing wall 112 can cause the housing wall 112 to impact the haptic dome 942a. When the bending or deformation exceeds a threshold amount, the haptic dome 942a may bend or collapse. For example, the haptic dome 942a can be formed of rubber, metal, and / or other materials that exhibit elastic deformation characteristics in response to an applied force. This can deliver a haptic output to the input area 116. In some cases, the collapse or bending of the haptic dome 942a can trigger a switch event. For example, the haptic dome 942a can contact one or more electrical contacts ( Figure 9A not shown in Figure 9AAs shown, the haptic membrane 942a can surround the light source 136. In this regard, the haptic membrane 942a can be a transparent structure, a perforated structure, or other structure that allows light from the light source 136 to propagate toward the outer surface 113.

[0164] Reference Figure 9B , the electronic device 104 is shown as having an electroactive polymer (EAP) or a piezoelectric stack, such as stack 942b. The stack 942b can be positioned within the internal volume 109 and extend between the internal support 111 and the opaque shielding layer 132 and / or the housing wall 112. Generally speaking, the stack 942b can be a series of alternating structures that stretch and / or contract in response to a signal. For example, the stack 942b can be a series of alternating electrodes separated by flexible members; in response to a signal, the electrodes can move relative to each other and then stretch and / or contract one or more flexible members. Such stretching and / or contraction can cause the housing wall 112 to translate or bend within the input region 116. In addition or alternatively, the stack 942b can be a series of alternating piezoelectric materials or piezoelectric strips that are arranged in a stack and configured to deflect or deform in response to a signal. The stack 942b can also be used to trigger a switching event. For example, a series of alternating electrodes and / or piezoelectric strips can exhibit a change in electrical properties (e.g., voltage, current, etc.) in response to strain or compression, which can be used to estimate the force input received within the input region 116.

[0165] Reference Figure 9C, the electronic device 104 is shown as having a magnetically based sensor 942c. The magnetically based sensor 942c can be an electromagnet or other device that uses magnetic field variations to convey a haptic output and / or trigger a switch event. In one embodiment, the magnetically based sensor 942c can include a first biasing element 952 positioned on an internal support 111 and a second biasing element 954 positioned on or below an opaque shielding layer 132 and / or a housing wall 112. The magnetically based sensor 942c can detect variations in the magnetic field between the first biasing element and the second biasing elements 952 and 954. This can be used to trigger a switch event. For example, the housing wall 112 can deform or partially bend into the internal volume 109 in response to a force input within the input region 116. This can cause a change in the spacing between the first biasing element and the second biasing elements 952 and 954. Such a change can be correlated with the bending of the housing wall 112 to estimate the force input received within the input region 116. The magnetically based sensor 942c can also be used to convey a haptic output to the input region 116. For example, the first biasing element and the second biasing elements 952 and 954 can be configured to move relative to each other in response to an input signal. Such relative movement of the first biasing element and the second biasing elements 952 and 954 can cause the housing wall 112 to temporarily vibrate or shift within the input region 116 in response to the input and thereby generate a haptic output. In some cases, the first biasing element and the second biasing elements 952 and 954 can be components of a voice coil or a magnetoresistive actuator.

[0166] Reference Figure 9D , the electronic device 104 is shown as having an optical sensor 942d. The optical sensor 942d can emit a signal along an optical path OP that extends towards an opaque shielding layer 132 and / or a housing wall 112. The optical sensor 942d can detect the reflection or propagation of the emitted signal along the optical path OP to estimate movement of the housing wall 112. For example, movement of the housing wall 112 can change the distance of the optical path OP, which can be detected by the optical sensor 942d. As described herein, the housing wall 112 can bend or at least partially deflect into the internal volume 109 in response to a force input. In this way, the optical sensor 942d can correlate the changed optical path OP with the bending of the housing wall 112 to estimate the force input received within the input region 116.

[0167] Reference Figure 9E, the electronic device 104 is shown as having a capacitance-based sensor 942e. The capacitance-based sensor 942e uses capacitance changes to detect inputs within the input region 116. In one embodiment, the capacitance-based sensor 942e may include a first capacitive element 962 positioned on an internal support 111 and a second capacitive element 964 positioned on or below an opaque shielding layer 132 and / or a housing wall 112. The second capacitive element 964 may include openings similar to the micro-perforation array 134 such that light can pass through the second capacitive element 964 and out of the internal volume of the electronic device 104. The capacitance-based sensor 942e may detect capacitance changes between the first capacitive element and the second capacitive elements 962, 964. This can be used to trigger a switching event. For example, the housing wall 112 may deform or partially bend into the internal volume 109 in response to a force input within the input region 116. This can cause a change in the spacing between the first capacitive element and the second capacitive elements 962, 964. This change can be correlated with the bending of the housing wall 112 to estimate the force input received within the input region 116. Additionally or alternatively, the capacitance-based sensor 942e may form a mutual capacitance or self-capacitance configuration where the capacitive elements of the actuator 942f can detect touch inputs (contacts) or the proximity of a user relative to the housing wall 112. For example, the capacitance-based sensor 942e may estimate a user's touch input or proximity by detecting changes in the capacitance measured at the capacitive elements.

[0168] Reference Figure 9F , the electronic device 104 is shown as having a shape memory alloy (“SMA”) component, such as the SMA component 942f. The SMA component 942f can be a wire or other metallic structure configured to deform in a pre-determined manner in response to a temperature change. The SMA component 942f may be positioned within the internal volume 109 and below the opaque shielding layer 132 and / or the housing wall 112. The SMA component 942f can be used to deliver a haptic effect to the housing wall 112 within the input region 116. By way of illustration, the SMA component 942f can be configured to return to its initial shape (from a deformed state) in response to heat. Thus, applying heat to the SMA component 942f can cause the SMA component 942f to apply a force on the housing wall 112 as the SMA component 942f attempts to return to its initial shape. This can cause the housing wall 112 to move and thereby provide a haptic or tactile output that can be perceived by the user.

[0169] Reference Figure 9G, the electronic device 104 is shown as having a strain gauge 942g. The strain gauge 942g can be positioned within the internal volume 109 and beneath the opaque shielding layer 132 and / or the housing wall 112. The strain gauge 942g can be used to deliver a haptic output to the housing wall 112. In one particular implementation, the strain gauge 942g can be formed of a piezoelectric material and positioned directly on or adjacent to a portion of the opaque shielding layer 132 and / or the housing wall 112. In a particular implementation, a voltage can be applied across the piezoelectric material such that the length of the piezoelectric material increases and / or decreases. To the extent that movement of the piezoelectric material is inhibited, the change in length of the piezoelectric material can cause the housing wall 112 to instantaneously bend or dent. The instantaneous bend or dent formed within the housing wall 112 can be haptically sensed by the user and thereby deliver haptic feedback to the user. In addition or alternatively, the strain gauge 942g can be used to measure a force input received at the housing wall 112 within the input region 116. For example, a force input received within the input region 116 can cause the housing wall 112 to bend or deflect into the internal volume and subsequently deform the strain gauge 942g. The strain gauge 942g can be configured to generate an electrical response in response to the deformation, and the electrical response can be used by the electronic device 104 to trigger a switching event.

[0170] Reference Figure 9H , the electronic device 104 is shown as having an electrostatic feedback component 942h. The electrostatic feedback component 942h can be positioned within the internal volume 109 and beneath the opaque shielding layer 132 and / or the housing wall 112. Generally speaking, the electrostatic feedback component 942h can be configured to charge the outer surface 113 of the housing wall 112. The user can haptically sense the charge on the outer surface 113. For example, the charge can be sensed as a resistance or impediment to movement on the outer surface 113. This can be beneficial for providing an indication or a haptic output similar to a physical button or key defined on the outer surface 113. In one embodiment, the electronic device 104 can display a notation indicating a slider knob or control on the outer surface 113, and the electrostatic feedback component 942h can be configured to generate a haptic output indicative of operating a physical knob or slider control.

[0171] Reference Figure 9I , the electronic device 104 is shown as having a mechanical spring 942i. The mechanical spring 942i can be a mechanical biasing element that provides haptic feedback to the housing wall 112. The mechanical spring 942i can extend between the internal support 111 and the opaque shielding layer 132 and / or the housing wall 112. The mechanical spring 942i can apply a compressive force on the housing wall 112, and the compressive force can increase as the housing wall 112 bends or deflects within the input region 116. In some embodiments, the mechanical spring 942i can be coupled to a contact or non-contact sensing element that can be used to trigger a switching event in response to an input within the input region 116.

[0172] Reference Figure 9J , the electronic device 104 is shown as having a thinning region 942j. The thinning region 942j can be a physical structure forming the housing wall 112. As Figure 9J shown, the thinning region 942j can be a part of the housing wall 112 with a reduced thickness. Compared with other non-thinning regions of the housing wall 112, the thinning region of the housing wall 112 can exhibit a regional tactile response. This can be used to indicate the presence or boundary of the input region 116 to the user. For example, as Figure 9J shown, the opaque shielding layer 132 and / or other components of the electronic device 104 can be located within the thinning region.

[0173] Figures 10A to 13C Various electronic devices with concealed or hideable input regions are depicted. Generally speaking, the input region can be formed on any outer surface of the electronic device. This can be the device housing, case, lid, panel, display shielding region, or other surfaces of the electronic device. In the unilluminated state, the input region can resemble a surface of the electronic device without input functionality. For example, as described herein, an opaque shielding layer with a micro-perforation array can be located beneath the housing wall forming the outer surface of the electronic device. The housing wall can be formed of or include a translucent layer and / or a metal layer. When unilluminated, the micro-perforation array may not be visually perceptible, and thus can be used to conceal or hide the input functionality from the user. The electronic device can then illuminate the micro-perforation array to display the input functionality of the input region. In some cases, one or more sensing elements, tactile structures, etc. can be located beneath the input region and used to detect inputs within the input region and / or transmit a tactile response.

[0174] Figure 10A The electronic device 1004 is depicted. The electronic device 1004 can be a laptop computer. For illustrative purposes, the electronic device 1004 is shown as having a housing 1008, a display 1020, and a translucent layer 1012. It should be noted that the electronic device 1004 can also include various other components, such as one or more ports (e.g., charging ports, data transfer ports, etc.), additional input / output buttons, etc. Thus, the discussion of any electronic device (such as the electronic device 1004) is only intended for illustration.

[0175] The housing 1108 can include various components that cooperate to form a laptop computer. As Figure 10AAs shown, the housing 1008 may include an upper portion 1008a and a lower portion 1008b. The first and second portions 1008a, 1008b may be pivotally coupled to each other about a hinge 1008c. The upper portion 1008a may include or define an opening. The display 1020 may be positioned within the opening. The lower portion 1008b may include or be partially formed by a housing wall 112. In this regard, a concealed or hideable input area may be defined on an outer surface of the lower portion 1008b. In some cases, the upper portion 1008a may also include a translucent layer or a translucent outer surface. This may allow the electronic device 1004 to define a concealed or hideable input area on a portion of the upper portion 1008a.

[0176] The electronic device 1004 may include a plurality of areas that may be defined on one or more surfaces of the housing 1008. As Figure 10A shown, the electronic device 1004 includes an input area 1016a, an input area 1016b, an input area 1016c, and an input area 1016d. When not illuminated, the input areas 1016a, 1016b, 1016c, 1016d may be substantially concealed or hidden from the user. When illuminated, the concealed input function of the input areas 1016a, 1016b, 1016c, 1016d may be displayed and used to control the functions of the electronic device 1004. The input areas 1016a, 1016b, 1016c, 1016d may be positioned or arranged on various surfaces formed by the housing 1008. As Figure 10A shown, the input areas 1016a, 1016b, and 1016c may be positioned on an outer surface of the electronic device 1004 defined by the lower portion 1008b, and the input area 1016d may be positioned on an outer surface of the electronic device 1004 defined by the upper portion 1008b. As described in more detail below with reference to Figure 10C different symbols may be illuminated on or within the input areas 1016a, 1016b, 1016c, 1016d, including functions and / or notifications related to a power button, a touchpad, a keyboard, and / or email or messaging related functions. In some cases, the input areas 1016a, 1016b, 1016c, 1016d may be configured to receive input for controlling the functions of the electronic device 1004 corresponding to the illuminated symbols.

[0177] Figure 10B Depicts a cross-sectional view of the input area taken along Figure 10A line B-B of Figure 10A The input area 1016a may be substantially similar to that described above with reference to Figures 1A to 9JThe input region 116 described. For example, the input region 1016a can be configured to display an illuminated symbol at the translucent layer 1012 and detect an input on the translucent layer 1012. In this regard, similar to the components described above with reference to Figures 1A to 9J The electronic device 1004 can include: a translucent layer 1012; an outer surface 1013; a lower surface 1014; an internal volume 1009; a support structure 1010; an internal support 1011; an opaque shielding layer 1032; a micro-perforation array 1034; and an optical path L1. The electronic device 1004 can also include one or more actuators, sensing elements, haptic structures, etc. positioned within the internal volume 1009 and below the translucent layer 1112. This can be used to detect an input within the input region 1016a and transmit a haptic effect to the translucent layer 1012.

[0178] Figure 10C Depicts an electronic device 1004 having input regions 1016a, 1016b, 1016c, 1016d in an illuminated state. Each of the input regions 1016a, 1016b, 1016c, 1016d can display a unique illuminated symbol and / or be used to control a unique function of the electronic device 1004. By way of illustration, the input region 1016a can include an illuminated symbol 1028a. The illuminated symbol 1028a can depict information related to a power button. The input region 1016a can be configured to detect an input that causes the electronic device 1004 to transition between various modes or power states (e.g., power on, power off, sleep, etc.). In some cases, the illuminated symbol 1028a is dark or invisible until the device receives an input, which can include a touch input or a force input along the input region 1016a or along another input region, key, or button of the device.

[0179] The input region 1016b may include an illuminated symbol 1028b. The illuminated symbol 1028b may depict information related to the boundary of the touchpad. The input region 1016b may be configured to detect an input that causes the electronic device 1004 to operate a cursor or other mark depicted at the display 1020 (e.g., such that the input region 1016b functions as a computer touchpad). The input region 1016c may include an illuminated symbol 1028c. The illuminated symbol 1028c may depict information related to one or more boundaries of a keyboard key. The input region 1016c may be configured to detect an input that causes the electronic device 1004 to generate an output corresponding to a keyboard key (e.g., such that the input region 1016c functions as a computer keyboard). The input region 1016d may include an illuminated symbol 1028d. The illuminated symbol 1028d may depict information related to an "email" notification or push. The input region 1016d may be configured to detect an input that causes the electronic device 1004 to access information associated with an email message.

[0180] In some embodiments, the input regions 1016a, 1016b, 1016c, 1016d do not need to receive input or be used to control the functions of the electronic device 1004; rather, the illuminated symbols may indicate notifications or status of the electronic device 1004. For example, the illuminated symbol 1028d may indicate a notification of an incoming email message and is not configured to receive input or be associated with a specific input function. Generally speaking, the illuminated symbols may be positioned along a surface of the device that is not configured to receive input and may be merely selectively illuminated visual indicators.

[0181] Each of the input regions 1016a, 1016b, 1016c, 1016d may be configured to manipulate the graphical output of the display 1020 in a different manner. For example, when the illuminated symbol 1028a is depicted, the input region 1016a may manipulate the graphical output of the display 1020 in a first manner. This may include presenting information at the display 1020 that corresponds to or is based on the illuminated symbol 1028a. Additionally, when the illuminated symbol 1028b is depicted, the input region 1016b may manipulate the graphical output of the display 1020 in a second manner. This may include presenting information at the display 1020 that corresponds to or is based on the illuminated symbol 1028b. Additionally, when the illuminated symbol 1028c is depicted, the input region 1016c may manipulate the graphical output of the display 1020 in a third manner. This may include presenting information at the display 1020 that corresponds to or is based on the illuminated symbol 1028c. Additionally, when the illuminated symbol 1028d is depicted, the input region 1016d may manipulate the graphical output of the display 1020 in a fourth manner. This may include presenting information at the display 1020 that corresponds to or is based on the illuminated symbol 1028d.

[0182] The electronic device 1004 can deliver haptic output to the input regions 1016a, 1016b, 1016c, 1016d. This can be used to simulate or mimic the feel of mechanical or physical buttons. For example, the electronic device 1004 can cause a haptic structure located within the housing 1008 to vibrate, translate, or in other words move the translucent layer 1112.

[0183] Figure 10D A side view of the electronic device 1004 in a closed position is depicted. For example, the first and second portions 1008a, 1008b can pivot relative to each other about the hinge 1008c such that the first and second portions 1008a, 1008b contact each other to define the closed position.

[0184] When the electronic device 1004 is in the reference Figure 10D closed position depicted, the input regions described herein can be used to control the functions of the electronic device 1004. For example, the input regions can be defined along the outer surface of the housing 1008 that is accessible to a user when the electronic device 1004 is in the closed position. As Figure 10D shown, the input region 1016a can be defined on the side surface of the lower portion 1008b. For example, the translucent layer 1112 can be or form the side wall of the lower portion 1008b. The input region 1016a defined on the side wall can be configured to receive an input that can be used to control the functions of the electronic device 1004. For example, as indicated by the illuminated symbol 1028a, this can be useful for controlling the power function of the electronic device 1004.

[0185] Figure 11A An electronic device 1104 is depicted. The electronic device 1104 can be a mobile phone. For illustrative purposes, the electronic device 1104 is shown as having a housing 1108, a display 1120, a translucent layer 1112, one or more input / output members 1106, and a speaker 1107.

The electronic device 1104 can include a translucent layer 1112 that forms the bottom surface of the housing 1108. As Figure 11B shown, the electronic device 1104 can include an input region 1116. When not illuminated, the input region 1116 can be substantially concealed or hidden from the user. When illuminated (as Figure 11DAs shown, the electronic device 1104 can display the hidden input function of the input area 1116. As described in more detail below, the input area 1116 can control various functions and / or provide various notifications associated with the electronic device 1104.

The input area 1016 can be configured to detect an input that causes the electronic device 1104 to access information associated with an email message. In some embodiments, the input area 1116 does not need to be configured to receive inputs or be used to control the functions of the electronic device 1104; instead, the illuminated symbol 1124 can simply indicate a notification or provide other visual information. For example, the illuminated symbol 1128 can be displayed along the outer surface of the device, which is not configured to receive inputs or provide a specific input function associated with the illuminated symbol 1128. The electronic device 1104 can deliver a haptic output to the input area 1116. This can be used to simulate or mimic the feel of a mechanical or physical button. For example, the electronic device 1104 can cause a haptic structure positioned within the housing 1108 to vibrate, translate, or in other words provide haptic feedback to the translucent layer 1112.

The stylus can be used to provide input to an associated electronic device (such as a tablet or a smart phone) by interacting with a touch-sensitive surface of the associated electronic device. For illustrative purposes, the electronic device 1204 is shown as having a body 1208 and a tip 1206. For example, a user can manipulate the body 1208 to provide information to the associated electronic device by moving the tip 1206 relative to the touch-sensitive surface of the associated electronic device. It should be noted that the electronic device 1204 can also include various other components, such as one or more ports (e.g., a charging port, a data transfer port, etc.), additional input / output buttons, etc. Thus, the discussion of any electronic device (such as the electronic device 1204) is only intended for illustration.

[0190] As ​ shown, the electronic device 1204 can include an input area 1216. When not illuminated, the input area 1216 can be substantially concealed or hidden from the user.

The input area 1216a can be substantially similar to the input area 116 described above with reference to Figures 1A to 9J . For example, the input area 1216 can be configured to display illuminated symbols at the translucent layer 1212 and detect input on the translucent layer 1212. In this regard, similar to the components described above with reference to Figures 1A to 9J , the electronic device 1204 can include: a translucent layer 1212; an outer surface 1213; a lower surface 1214; an internal volume 1209; a support structure 1210; an internal support 1211; an opaque shielding layer 1232; a micro-perforation array 1234; and an optical path L1.

[0192] Figure 12CDepicts an electronic device 1204 having an input region 1216 in an illuminated state. The input region 1216 can display one or more different illuminated symbols and / or be used to control various different functions of the electronic device 1204. For illustration, the input region 1216 can include an illuminated symbol 1228. The illuminated symbol 1228 can depict information related to an "email" notification or command. The input region 1216 can be configured to detect an input that causes the electronic device 1204 to access information associated with an email message. However, it should be understood that the input region 1216 does not need to be configured to receive an input or be used to control the functions of the electronic device 1204; rather, the illuminated symbol 1228 can indicate a notification. For example, an illuminated symbol 1228 displayed along the outer surface of the device can indicate a notification of an incoming email message, and the surface may not be configured to receive an input or be associated with a specific input function (e.g., the surface can be touch-sensitive but not configured as a dedicated button or input region). The electronic device 1204 can deliver a haptic output to the input region 1216. This can be used to simulate or mimic the feel of a mechanical or physical button. For example, the electronic device 1204 can cause a haptic structure located within the body 1208 to vibrate, translate, or in other words provide haptic feedback to the translucent layer 1212.

For purposes of illustration, the watch is shown as having a watch body 1308, a crown 1306, a display 1312, and a watch band 1324. The display 1312 can be positioned in a first opening defined by the housing 1308, and the crown 1306 can be at least partially positioned in a second opening defined by the housing 1308. The display 1312 can respond to translational and rotational movements of the crown 1306.

[0196] Figure 13C Depicts the electronic device 1304 with the input region 1316 in an illuminated state. The input region 1316 can display one or more different illuminated symbols and / or be used to control various different functions of the electronic device 1304. For illustration, the input region 1316 can include an illuminated symbol 1328. The illuminated symbol 1328 can depict information related to an "email" notification or command. The input region 1316 can be configured to detect an input that causes the electronic device 1304 to access information associated with an email message. However, it should be understood that the input region 1316 does not need to be configured to receive inputs or be used to control the functions of the electronic device 1304; rather, the illuminated symbol 1328 can indicate a notification. For example, the illuminated symbol 1328 can indicate a notification of an incoming email message and may not be configured to receive inputs or be associated with a specific input function. The electronic device 1304 can deliver a haptic output to the input region 1316. This can be used to simulate or mimic the feel of a mechanical or physical button. For example, the electronic device 1304 can cause a haptic structure positioned within the body 1308 to vibrate, translate, or in other words provide haptic feedback to the translucent layer 1312.
