Referring to
Each of the plurality of display panels 110a, 110b, 110c may have a first viewing surface 130a, 130b, 130c on which a textual and/or graphical display may be provided. The viewings surfaces 130a, 130b, 130c may include display pixels configured to be selectively powered on by row and column drivers. Alternately, in some embodiments, the first viewing surface 130a, 130b, 130c may be configured to display a blank screen. In some embodiments, a display panel having a first viewing surface may also have a second viewing surface. The first viewing surface may be on a first side of the display panel and the second viewing surface may be on a second side of the same display panel. In some embodiments, the second side of the display panel may be opposite the first side of the display panel, on the reverse side of the display panel. Display panels 110a, 110b, 110c may be configured to provide a display on the first viewing surface 130a, 130b, 130c and/or the second viewing surface.
In various embodiments, the display panels may be any type of display panel allowing display of textual and/or graphical information. In one embodiment, the display panels 110a, 110b, 110c may be substantially identical in structure or functionality. By way of example, but not limitation, each of the display panels 110a, 110b, 110c may be an E-ink e-paper display (“EPD”) panel. In another embodiment, one or more of the display panels may differ in structure or functionality. By way of example, but not limitation, one or more of the display panels 110a, 110b, 110c may be an EPD display panel, a thin film transistor (“TFT”)-based display panel and/or a touch-enabled display panel. TFT-based display panels may enable fast navigation speed, and/or precise color and video display.
Touch-enabled display panels may provide for device navigation, keyboard or virtual keypad functionality. Any touch technology may be used including, but not limited to, resistive or capacitive technologies. The touch technology may be the same on each of display panels 110a, 110b, 110c or the technology may differ across display panels 110a, 110b, 110c. For example, the technology may differ to support more complex capabilities, such as multi-finger input or pen-based input, or less complex capabilities, which may result in lower cost and/or lower power consumption.
In various embodiments, touch sensors (not shown) may be placed in a display area other than on the first viewing surface 130a, 130b, 130c. In one embodiment, the touch sensors may be placed in the bezel area of the first viewing surface 130a, 130b, 130c. In some embodiments, touch capability may be implemented by identifying an interruption (by a user's finger or otherwise) of an infrared beam provided to or from one or more of the display panels 110a, 110b, 110c. In some embodiments, the device 100 may have infrared touch capability without the use of bezels.
In other embodiments, the back of any display panel may include a capacitive button that operates as a touch pad or a rocker switch. The button may be used to interact with a type of information content displayed on the first viewing surface 130a, 130b, 130c and/or the second viewing surface of one of display panels 110a, 110b, 110c.
In one embodiment, one or more of the display panels 110a, 110b, 110c may be configured to display a blank screen or be a bistable display panel configured to provide a static display of the last image provided on the display panel before power was removed from or reduced in the display panel. The last image may be displayed until the power is applied to or increased in the display panel, and the image refreshed. In some embodiments, the bistable display panel may be the display panel of the E-ink® e-paper device, the Bridgestone Corporation QR-LPD® e-paper device or the display panel of other similar technology. Controlling one or more display panels independent of the other display panels may provide for decreased power consumption and battery conservation.
In one embodiment, each display panel 110a, 110b, 110c may be sufficiently thin to allow the device 100 to be completely collapsed. The display panel 110a, 110b, 110c may alternately be partially or completely expanded. As used herein, the term “completely expanded” means a configuration of the device wherein the first viewing surface of the leftmost display panel and the first viewing surface of the rightmost display panel form an angle of approximately 180 degrees (e.g., 180 degrees±2 degrees). In one embodiment, the device may be planar.
The connectors 120a, 120b may be any flexible material allowing the device 100 to be manipulated into a completely expanded configuration, a partially expanded configuration and/or a completely collapsed configuration. By way of example, but not limitation, the connectors 120a, 120b may be mechanical hinges, flexible plastic and/or cloth.
Any two of the display panels 110a, 110b, 110c may be coupled to one of the connectors 120a, 120b thereby coupling the two display panels together. In some embodiments, three or more display panels 110a, 110b, 110c may be coupled to a single connector.
In one embodiment, connectors 120a, 120b may also include communication media configured to transport information across the connectors 120a, 120b from one display panel to one or more of the other display panels. In one embodiment, the communication media may be adapted to communicate information by electrical signals. The communication media may include, but is not limited to, electrical conductors such as wires or flexible printed circuit traces. In various embodiments, electrical signals may be communicated according to the low voltage differential signaling (“LVDS”) method or another low power, high bandwidth method. In other embodiments, the connectors 120a, 120b may include communication media for communicating information from one display panel to another display panel by optical or RF signals or by any other method that does not require the inclusion of electrical signal conductors. By way of example, but not limitation, short-range infrared power may be communicated through the communication media or through the air surrounding the device 100, to provide optical communication between display panels. By way of another example, very short range RF may be used for RF communication between display panels. The transmitter and/or the receiver providing the optical and RF communication may be communicatively coupled to the connectors 120a, 120b or to any location on the device 100.
Sensor 140a may be communicatively coupled to connector 120a and sensor 140b may be communicatively coupled to connector 120b. In the embodiment shown, the sensors 140a, 140b may he coupled to their respective connector; however, such physical connection may not be required.
The sensors 140a, 140b may be any type of device adapted to sense whether, and/or the degree to which, one or more of the connectors 120a, 120b is flexed. By way of example, but not limitation, the sensors 140a, 140b may be adapted to sense the degree to which one or more connectors 120a, 120b are flexed. The sensing may be used to determine whether the first viewing surfaces 130a, 130b, 130c of the display panels 110a, 110b, 110c are substantially parallel to one another, thereby causing the connector to be flexed at an angle of zero degrees. By way of another example, but not limitation, the sensor may be adapted to sense the degree to which one or more connectors 120a, 120b are flexed. The sensing may be used to determine whether the first viewing surfaces 130a, 130b, 130c of the display panels 110a, 110b, 110 are not substantially parallel to one another, thereby causing the connector to be flexed at an angle other than zero degrees. Accordingly, the one or more sensors 140a, 140b may be adapted to sense a selected one of the possible arrangements of the display panels 110a, 110b, 110c.
The sensors 140a, 140b may operate based on electrical, optical or RF technology. In various embodiments, the one or more sensors 140a, 140b may be electromechanical contacts, optical sensors, proximity sensors, camera arrays and/or strain gauges. In one embodiment, one or more of the sensors 140a, 140b may be the thin film Bend Sensor® manufactured by Flexpoint Flexible Sensor Systems of Draper, Utah, the optical HiTechnic NXT Color Sensor manufactured by HiTechnic and/or the Cypress Semiconductor proximity sensor such as that of the Cypress Semiconductor CY3235 kit.
The circuitry 300 may be adapted to receive from one or more of the sensors 140a, 140b sensed information regarding the arrangement of the display panels 110a, 110b, 110c, and determine the configuration of the device 100 based on the sensed information. The circuitry 300 may also be configured to control one or more of the display panels 110a, 110b, 110c to provide a display of a type of information content from the first viewing surface 130a, 130b, 130c, and/or the second viewing surface (not shown) of the respective display panel 110a, 110b, 110c. The circuitry 300 may also control a display panel to display a type of information content that is a single image on a selected one or more of the display panels, or a composite image across a plurality of the display panels. The control information may be communicated between one or more display panels via the connectors 120a, 120b, which may be communicatively coupled to the controller 310.
In one embodiment of the operation, the I/O device may receive information sensed by one or more of the sensors 140a, 140b and output the information to the sensor signal processor 320 of the controller 310. The sensor signal processor 320 may be adapted to determine whether and/or the degree to which one or more of the controllers 120a, 120b is flexed. The sensor signal processor 320 may output information indicative of the configuration of the device 100 to the display controller 340. The display controller 340 may output control information through the I/O device 360 to one or more row and/or column drivers that may be communicatively coupled to pixels (not shown) associated with display panels 110a, 110b, 110c. The control information may control one or more row and/or column drivers to display a type of information content indicative of the determination made by the sensor signal processor 320 and/or cause the power to the display panel 110a, 110b, 110c to be reduced or modified. Accordingly, in some embodiments, the device 100 may conserve power by having one or more display panels selectively turned off.
In one embodiment, circuitry 300 may be communicatively coupled to each of the display panels 110a, 110b, 110c and may control each of the display panels 110a, 110b, 110c. In another embodiment, circuitry 300 may be communicatively coupled to a single display panel for controlling only the display of a single display panel. In the latter embodiment, each display panel 110a, 110b, 110c may be controlled by individual circuitry 300. For example, each of display panels 110a, 110b, 110c may be controlled by a circuit similar in connectivity and/or function of circuitry 300.
In operation, the type of information content displayed may be selected according to the arrangement of the display panels 110a, 110b, 110c relative to one another. A user of the device 100 may arrange the display panels 110a, 110b, 110c in a selected one of a plurality of possible arrangements, which result in a selected configuration of the device. The configuration may be a partially or completely expanded configuration or a completely collapsed configuration.
As shown in
As shown in
In other embodiments, when the device 500 is in a completely collapsed configuration, the device 500 may provide a bistable display or a blank screen on one or more of the display panels 510a, 510b, 510c.
With reference to
The power provided to the devices 100, 200, 400, 500 or the controller 300, which may be communicatively coupled to or provided within the devices 100, 200, 400, 500, may be provided by way of various different embodiments. In one embodiment, the power may be provided by electrical signal conductors such as wires, or by flexible printed circuit traces coupled to a battery subsystem. In some embodiments, the battery subsystem may include individual batteries respectively coupled to each display panel of the device 100, 200, 400, 500. In another embodiment, power may be provided by operably coupling the device 100, 200, 400, 500 to a power plug that may be connected to an electrical socket, and/or operably coupling the device 100, 200, 400, 500 to a solar cell.
In another embodiment, power may be provided via surface contacts that provide an electrical path when the device 100, 200, 400, 500 is completely collapsed, but are not connected to the device 100, 200, 400, 500 when the device 100, 200, 400, 500 is completely or partially expanded. In yet another embodiment, the power may be provided inductively. The latter two aforementioned embodiments may advantageously enable the outer surface of the device 100, 200, 400, 500 to be sealed to improve the protection of the device from moisture and dust, and enable less complex and slimmer connectors.
