Conventional displays as used in bicycle computers, smart phones, smartwatches, GPS navigation devices, fitness trackers, etc. utilize display modules to provide a user interface to users of the electronic devices. These electronic devices may or may not employ a touchscreen. Where a touchscreen is not provided, buttons and other user input devices are used to receive user input. Battery life is important for these devices as it is aggravating for users to stop wearing a device for recharging. Some attempts have been made to equip smartwatches with semitransparent solar panels such as by using a discrete solar cell positioned on top of (or over) the watch's display. However, the presence of such a solar cell overlay degrades visibility of the display module. Accordingly, there is a need for an integrated energy-collecting display module that collects solar energy without substantially obscuring its display.
Techniques are disclosed to enable an energy-collecting display module having a base substrate with a plurality of sub-pixels, which are laid out in a substantially regular sub-pixel pattern. The sub-pixels are dispersed along the base substrate with sub-pixel spacing regions between individual sub-pixels. The modules also include a top substrate disposed opposite to and above the base substrate and a photovoltaic region disposed between the base substrate and the top substrate within the sub-pixel spacing regions.
The figures described below depict various aspects of the articles of manufacture disclosed herein. It is understood that these figures depict exemplary embodiments and particular aspects of the disclosed articles of manufacture. The exemplary features illustrated in the figures are intended to represent these aspects of the various disclosed embodiments and not intended to limit the claimed scope to any particular feature. Further, whenever possible, the following description refers to the reference numerals included in the figures, in which features depicted in multiple figures are designated with consistent reference numerals.
The following text sets forth a detailed description of numerous different embodiments. However, it is understood that the detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical. In light of the teachings and disclosures herein, numerous alternative embodiments may be implemented.
It is understood that, unless a term is expressly defined in this patent application using the sentence “As used herein, the term ‘______’ is hereby defined to mean . . . ” or a similar sentence, there is no intent to limit the meaning of that term, either expressly or by implication, beyond its plain or ordinary meaning, and such term should not be interpreted to be limited in scope based on any statement made in any section of this patent application.
A single pixel on a color sub-pixelated display is made of several color primaries, typically three colored elements—ordered (on various displays) either as blue, green, and red (BGR), or as red, green, and blue (RGB). Some displays have more than three primaries, often called MultiPrimary, such as the combination of red, green, blue, and yellow (RGBY), or red, green, blue and white (RGBW), or even red, green, blue, yellow, and cyan (RGBYC).
These pixel components, sometimes called sub-pixels, appear as a single color to the human eye because of blurring by the optics and spatial integration by nerve cells in the eye. The components are easily visible, however, when viewed with a small magnifying glass, such as a loupe. Over a certain resolution threshold the colors in the subpixels are not visible, but the relative intensity of the components shifts the apparent position or orientation of a line.

Functions of the watch 10 may be associated with a location determining component 142 (of
The location determining component 142 may be a GPS receiver that is configured to provide geographic location information of the watch. The location determining component 142 may be, for example, a GPS receiver such as those provided in various products by GARMIN®. Generally, GPS is a satellite-based radio navigation system capable of determining continuous position, velocity, time, and direction information. Multiple users may simultaneously utilize GPS. GPS incorporates a plurality of GPS satellites that orbit the earth. Based on these orbits, GPS satellites can relay their location to a GPS receiver. For example, upon receiving a GPS signal, e.g., a radio signal, from a GPS satellite, the watch disclosed herein can determine a location of that satellite. The watch can continue scanning for GPS signals until it has acquired a number, e.g., at least three, of different GPS satellite signals. The watch may employ geometrical triangulation, e.g., where the watch utilizes the known GPS satellite positions to determine a position of the watch relative to the GPS satellites. Geographic location information and/or velocity information can be updated, e.g., in real time on a continuous basis, for the watch.
The location determining component 142 may also be configured to provide a variety of other position-determining functionality. Location determining functionality, for purposes of discussion herein, may relate to a variety of different navigation techniques and other techniques that may be supported by “knowing” one or more positions. For instance, location determining functionality may be employed to provide position/location information, timing information, speed information, and a variety of other navigation-related data. Accordingly, the location determining component 142 may be configured in a variety of ways to perform a wide variety of functions. For example, the location determining component 142 may be configured for outdoor navigation, vehicle navigation, aerial navigation (e.g., for airplanes, helicopters), marine navigation, personal use (e.g., as a part of fitness-related equipment), and so forth. Accordingly, the location determining component 142 may include a variety of devices to determine position using one or more of the techniques previously described.
The location determining component 142, for instance, may use signal data received via a GPS receiver in combination with map data that is stored in the memory to generate navigation instructions (e.g., turn-by-turn instructions to an input destination or point of interest), show a current position on a map, and so on. Location determining component 142 may include one or more antennas 111 to receive signal data as well as to perform other communications, such as communication via one or more networks. The location determining component 142 may also provide other positioning functionality, such as to determine an average speed, calculate an arrival time, and so on.
The location determining component 142 may include one or more processors, controllers, and/or other computing devices as well as a memory 108, e.g., for storing information accessed and/or generated by the processors or other computing devices. The processor may be electrically coupled with a printed circuit board and operable to process position determining signals received by the antenna 111. The location determining component 142, e.g., the antenna 111, is configured to receive position determining signals, such as GPS signals from GPS satellites, to determine a current geographic location of the watch. The location determining component 142 may also be configured to calculate a route to a desired location, provide instructions, e.g., directions, to navigate to the desired location, display maps and other information on the display, and to execute other functions, such as, but not limited to, those functions described herein.
The memory may store cartographic data and routing used by or generated by the location determining component 142. The memory may be integral with the location determining component 142, stand-alone memory, or a combination of both. The memory 108 may include, for example, a removable nonvolatile memory card, such as a TransFlash card. The memory is an example of device-readable storage media that provides storage functionality to store various data associated with the operation of the watch 10, such as the software program and code segments mentioned above, or other data to instruct the processor and other elements of the watch 10 to perform the techniques described herein. A wide variety of types and combinations of memory may be employed. The memory may be integral with the processor, stand-alone memory, or a combination of both. The memory may include, for example, removable and non-removable memory elements such as RAM, ROM, Flash (e.g., SD Card, mini-SD card, micro-SD Card), magnetic, optical, USB memory devices, and so forth.
The antenna 111, for example, may be configured to receive and/or transmit a signal, such as a GPS signal. Antenna 111 may be any antenna capable of receiving wireless signals from a remote source, including directional antennas and omnidirectional antennas. Antenna 111 may include any type of antennas in which the length of the ground plane affects the efficiency of the antenna. In accordance with one or more embodiments of the present disclosure, the antenna 111 is an omnidirectional antenna having a ground plane. An omnidirectional antenna may receive and/or transmit in both orthogonal polarizations, depending upon direction. In other words, omnidirectional antennas do not have a predominant direction of reception and/or transmission. Examples of omnidirectional antennas include, but are not limited to, inverted-F antennas (IFAs) and planar inverted-F antennas (PIFAs). In contrast to omnidirectional antennas, directional antennas have a primary lobe of reception and/or transmission over an approximate 70 by 70 degree sector in a direction away from the ground plane. Examples of directional antennas include, but are not limited to, microstrip antennas and patch antennas.
In accordance with one or more embodiments of the present disclosure, the antenna 111 may be an embedded antenna. As used herein, an embedded antenna refers to an antenna that is positioned completely within a device housing. For example, the antenna 111 may be positioned completely within the housing 102. In some embodiments, the antenna 111 may be an external antenna with all or a portion of the antenna 111 exposed from the housing 102.
As discussed, the location determining component 142 includes the antenna 111. The antenna 111 may be associated with, e.g., formed on and/or within, an antenna support assembly. Alternatively, the antenna 111 may be positioned on a top portion or one or more side portions of the antenna support assembly.
The printed circuit board may support a number of processors (such as processor 106), microprocessors, controllers, microcontrollers, programmable intelligent computers (PIC), field-programmable gate arrays (FPGA), other processing components, other field logic devices, application specific integrated circuits (ASIC), and/or a memory that is configured to access and/or store information that is received or generated by the watch. The watch 10 may implement one or more software programs to control text and/or graphical information on the display, as discussed herein. As an example, the printed circuit board may support the bottom portion of the antenna support assembly. In some embodiments, the antenna support assembly and antenna 111 may be positioned in the center of the top surface, bottom surface, or to a side of the of the printed circuit board.
The processor 106 may provide processing functionality for the watch 10 and may include any number of processors, micro-controllers, or other processing systems, and resident or external memory for storing data and other information accessed or generated by the watch 10. The processor may execute one or more software programs that implement the techniques and modules described herein. The processor is not limited by the materials from which it is formed or the processing mechanisms employed therein and, as such, may be implemented via semiconductor(s) and/or transistors (e.g., electronic integrated circuits (ICs)), and so forth.
In accordance with one or more embodiments of the present disclosure, functions of the portable electronic device may be associated with the location determining component 142 and/or an associated performance monitoring component (not shown). For example, the location determining component 142 is configured to receive signals, e.g. position determining signals, such as GPS signals, to determine a position of the watch as a function of the signals. The location determining component 142 may also be configured to calculate a route to a desired location, provide instructions to navigate to the desired location, display maps and/or other information in the viewing area 104, to execute other functions described herein, among other things.
The performance monitoring component may be positioned within the housing 102 and be coupled to the location determining component 142 and the viewing area 104 of
In embodiments, the watch 10 includes a user interface, which is storable in memory and executable by the processor. The user interface is representative of functionality to control the display of information and data to the user of the watch 10 in the viewing area 104. In some implementations, a display module within the viewing area 104 may not be integrated into the smartwatch and may instead be connected externally using universal serial bus (USB), Ethernet, serial connections, and so forth. The user interface may provide functionality to allow the user to interact with one or more applications of the watch 10 by providing inputs via the touch screen and/or the I/O devices. For example, the user interface may cause an application programming interface (API) to be generated to expose functionality to an application to configure the application for display in the viewing area 104 or in combination with another display. In embodiments, the API may further expose functionality to configure the application to allow the user to interact with an application by providing inputs via the touch screen and/or the I/O devices. Applications may comprise software, which is storable in memory and executable by the processor, to perform a specific operation or group of operations to furnish functionality to the watch 10. Example applications may include fitness application, exercise applications, health applications, diet applications, cellular telephone applications, instant messaging applications, email applications, photograph sharing applications, calendar applications, address book applications, and so forth.
In various embodiments, the user interface may include a browser (not shown). The browser enables the watch 10 to display and interact with content such as a webpage within the World Wide Web, a webpage provided by a web server in a private network, and so forth. The browser may be configured in a variety of ways. For example, the browser may be configured as an application accessed by the user interface. The browser may be a web browser suitable for use by a full resource device with substantial memory and processor resources (e.g., a smart phone, a personal digital assistant (PDA), etc.). However, in one or more implementations, the browser may be a mobile browser suitable for use by a low-resource device with limited memory and/or processing resources (e.g., a mobile telephone, a portable music device, a transportable entertainment device, etc.). Such mobile browsers typically conserve battery energy, memory and processor resources, but may offer fewer browser functions than web browsers.
In various embodiments, the watch 10 includes an energy storage device such as a battery 110. It is understood that this energy storage device could employ any conventional or later developed energy storage or chemical battery technology, such as a supercapacitor, for example employing electrostatic double-layer capacitance and electrochemical pseudocapacitance. In various embodiments the energy storage device or battery 110 includes a lithium polymer battery.

In an embodiment the photovoltaic material 240 is isolated from the electrode(s) by photovoltaic insulating layer 241. In various embodiments, the photovoltaic material 240 is formed from one or more layers of doped amorphous silicon which has the advantages of low cost as well as low toxicity compared to some other photovoltaic materials, but it is understood that other photovoltaic materials may be employed without departing from the present teachings. For example, silicon and/or micro (nano) crystalline silicon, oxidic silicon, thin film silicon, combinations thereof, and the like may be employed in addition to, or as an alternative to, amorphous silicon. Similarly, perovskite and combinations of perovskite and silicone may be employed by embodiments of the present invention. In various embodiments a pattern associated with the photovoltaic material 240 is formed by first depositing a substantially uniform layer or layers of photovoltaic material and then removing desired portions of the material by way of photoetching.
In various embodiments, photovoltaic energy is transmitted through the display module 20 into the photovoltaic layer made up of photovoltaic material 240 thus generating electrical current and, therefore, energy in the photovoltaic layer which is then collected by way of conductors eventually through power conditioning module 105 and into the battery 110 of
