DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Various aspects of the present disclosure will be described more fully below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout the present disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure encompasses any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with other aspects of the present disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects described herein. In addition, the scope of the present disclosure is intended to encompass such an apparatus or method practiced using other structures, functions, or structures and functions in addition to or other than the various aspects of the present disclosure described herein. It will be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0013] The user device may include a display device for presenting visual content to the user. In some cases, the display device may include a rollable display panel that may be expanded and / or contracted between a first portion and a second portion to adjust (e.g., increase or decrease) a visible portion of the display panel. The visible portion of the display device may be a portion of the display device that extends from and / or is disposed outside of an internal housing of the user device.

[0014] Typically, a mechanical device (e.g., a motor, a set of rollers, etc.) may be used to expand and / or contract the rollable display panel. In some cases, the mechanical device may be calibrated to allow a controller of the user device to control the size of the visible portion of the rollable display panel, to allow the rollable display panel to be uniformly expanded and / or contracted (e.g., to allow the bottom and top edges of the rollable display panel to expand at the same rate), etc. However, over time, dust, temperature, shocks caused by dropping the user device, etc. may cause physical changes to the mechanical device, which may affect the operation of the mechanical device. For example, physical changes to the mechanical device may affect the calibration of the mechanical device, which may prevent the controller from accurately controlling and / or determining the size of the visible portion of the rollable display panel and / or may prevent the rollable display panel from being uniformly expanded and / or contracted. Furthermore, failure to accurately control and / or determine the size of the visible portion may lead to content being displayed on a portion of the rollable display panel disposed within the internal housing of the user device, which may result in undesirable power consumption.

[0015] Some implementations described herein enable a display device of a user device to accurately determine a current size of a visible portion of a rollable display panel and configure output settings for displayed content based on the current size of the visible portion. For example, the display device may receive distance measurements from a sensor. The distance measurements may indicate dimensions of the rollable display panel (e.g., the size of the visible portion). The display device may configure output settings for displayed content of the rollable display panel based on the distance measurements and / or the dimensions of the rollable display panel.

[0016] In this manner, the display device may accurately determine the size of the visible portion of the rollable display panel. Additionally, the display device may use the distance measurements to determine the accuracy of a mechanical device configured to expand and / or contract the rollable display panel. For example, the mechanical device may include a stepper motor that provides a count of a counter mechanism that indicates the number of revolutions of the motor relative to the display device. The display device may determine the accuracy of the motor based on comparing the size of the visible portion indicated by the number of revolutions of the motor with the size of the visible portion indicated by the distance measurements. The display device may cause the motor to be recalibrated when the accuracy meets a threshold value.

[0025] Input components 225 include components that enable device 200 to receive information, such as via user input (e.g., a touchscreen display, a keyboard, a keypad, a mouse, buttons, switches, and / or a microphone). Additionally or alternatively, input components 225 may include components for determining the position or location of device 200 (e.g., a Global Positioning System (GPS) component or a Global Navigation Satellite System (GNSS) component) and / or sensors for sensing information (e.g., an accelerometer, a gyroscope, an actuator, or another type of position or environmental sensor). Output components 230 include components that provide output information from device 200 (e.g., a display, a speaker, a haptic feedback component, and / or an audio or visual indicator).

[0026] The communications interface 235 includes transceiver-like components (e.g., a transceiver and / or a separate receiver and transmitter) that enable the device 200 to communicate with other devices, such as via a wired connection, a wireless connection, or a combination of wired and wireless connections. The communications interface 235 may enable the device 200 to receive information from and / or provide information to another device. For example, the communications interface 235 may include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency interface, a universal serial bus (USB) interface, a wireless local area interface (e.g., a Wi-Fi interface), and / or a cellular network interface.

[0027] Sensor 240 includes one or more devices capable of sensing a characteristic associated with device 200. Sensor 240 may include one or more integrated circuits (e.g., on a packaged silicon die) and / or one or more passive components of one or more flex circuits to enable communication with one or more components of device 200.

[0028] In some aspects, the sensor 240 may include an optical sensor capable of obtaining data indicative of a dimension of a rollable display panel of a display device, as described herein. The optical sensor may include an emitter capable of emitting a pulse of light and an optical receiver capable of receiving the pulse of light and / or a reflection of the pulse of light.

[0029] Sensor 240 may include an optical sensor having a field of view from which sensor 240 may determine one or more characteristics of device 200's environment. In some aspects, sensor 240 may include a camera. For example, sensor 240 may include a low-resolution camera (e.g., video flux array (VGA)) capable of capturing images of less than 1 megapixel, images of less than 1216×912 pixels, etc. Sensor 240 may be a low-power device (e.g., a device consuming less than 10 milliwatts of power) with always-on capabilities (e.g., to enable always-on face detection, always-on character recognition, always-on object detection, etc.) while device 200 is powered on.

[0030] Additionally or alternatively, the sensors 240 may include magnetometers (e.g., Hall effect sensors, anisotropic magnetoresistance (AMR) sensors, giant magnetoresistance sensors (GMR), etc.), location sensors (e.g., GPS receivers, local positioning system (LPS) devices (e.g., using triangulation and / or multilateration, among other examples), etc.), gyroscopes (e.g., microelectromechanical systems (MEMS) gyroscopes or similar type devices), accelerometers, speed sensors, motion sensors, infrared sensors, temperature sensors, pressure sensors, etc.

[0031] The rollable display panel 245 includes an output surface capable of using image projection technology (e.g., liquid crystal display (LCD), light emitting diode (LED), organic LED (OLED), gas plasma, etc.) to present content in a visual form. The rollable display panel 245 may include a flexible structure that allows at least a portion of the rollable display panel 245 to expand from and / or contract into a device (e.g., user device 110 and / or wireless communication device 120) to change the size of the output surface used to present content in a visual form, as described herein.

[0032] The device 200 may perform one or more processes described herein. The device 200 may perform these processes based on the processor 210 executing software instructions stored by a non-transitory computer-readable medium, such as the memory 215 and / or the storage component 220. A computer-readable medium is defined herein as a non-transitory memory device. A memory device includes memory space within a single physical storage device or memory space spread across multiple physical storage devices.

[0033] Software instructions may be read into memory 215 and / or storage component 220 from another computer-readable medium or another device via communications interface 235. When executed, the software instructions stored in memory 215 and / or storage component 220 may cause processor 210 to perform one or more processes described herein. Additionally or alternatively, hardwired circuitry may be used in place of or in combination with software instructions to perform one or more processes described herein.

[0036] 3A and 3B are diagrams illustrating an example 300 relating to managing a rollable display panel of a display device according to the present disclosure. As shown in FIGS. 3A and 3B, a display device 305 of a user device 110 (e.g., display device 112) includes a rollable display panel 310, a main housing section 315, a roller housing section 320, a chassis 325, a sensor 240 (e.g., light emitter 330 and light receiver 335, as shown), a controller 340, and an adjustment mechanism 345. The rollable display panel 310, the main housing section 315, the roller housing section 320, the chassis 325, the sensor 240, the controller 340, and the adjustment mechanism 345 are described in more detail below.

[0037] 3A by reference numeral 350, the display device 305 adjusts the rollable display panel 310. A user may provide input to the user device 110. The input may be associated with adjusting the size of the visible portion of the rollable display panel 310. For example, the user may provide input via input elements displayed via the rollable display panel 310, physical buttons included on the main housing section 315 and / or roller housing section 320, etc.

[0038] The controller 340 may receive an input and cause the adjustment mechanism 345 to adjust the rollable display panel 310 based on the input. In some aspects, the input indicates a size of the visible portion of the rollable display panel 310. For example, the input may include a distance between an edge of the main housing section 315 and an edge of the roller housing, a length of a side of the rollable display panel 310 (e.g., a side adjacent to the main housing section 315), etc.

[0039] The controller 340 may determine a new size of the visible portion of the rollable display panel 310 based on the size of the visible portion indicated by the input. The controller 340 may determine the current size of the visible portion based on accessing information stored in a memory associated with the display device 305. For example, the information stored in the memory may include information indicating the current size of the visible portion of the rollable display panel 310, the current distance between an end of the main housing section 315 and the roller housing section 320, etc. The controller may determine the current size of the visible portion based on the information indicating the current size of the visible portion of the rollable display panel 310, the current distance between an end of the main housing section 315 and the roller housing section 320, etc.

[0040] The controller 340 may determine a difference between the current size of the visible portion and the new size of the visible portion. The controller 340 may determine a size of a portion of the rollable display panel 310 to be extended from or retracted into the interior of the main housing section 315 based on the difference between the current size of the visible portion and the new size of the visible portion. The controller 340 may cause the adjustment mechanism 345 to adjust the rollable display panel 310 to account for the difference between the current size of the visible portion and the new size of the visible portion.

[0041] 3A, the controller 340 causes an adjustment mechanism 345 (shown in FIG. 3B) to transition the rollable display panel 310 from a fully retracted position to an extended position. In some aspects, the fully retracted position corresponds to a minimum size of a viewable portion of the rollable display panel 310. For example, in the fully retracted position, the roller housing section 320 may be disposed adjacent an end of the main housing section 315 and / or the distance between the light emitter 330 and the light receiver 335 may be a minimum distance (e.g., 0 cm, 0.1 cm, etc.).

[0042] In some aspects, the expanded position corresponds to a size of the visible portion of the rollable display panel 310 that is greater than a minimum size of the visible portion. For example, the expanded position may correspond to a fully expanded position (e.g., the size of the visible portion is a maximum size), a partially expanded position (e.g., the size of the visible portion is greater than a minimum size and / or less than a maximum size), etc.

[0043] As indicated by reference numeral 355, the controller 340 receives measurement data from the sensor 240 (e.g., the light emitter 330 and / or the light receiver 335 shown in FIG. 3A ). In some embodiments, the measurement data includes information identifying a distance between the main housing section 315 and the roller housing section 320. For example, the sensor 240 may obtain data indicative of the distance between the main housing section 315 and the roller housing section 320. The sensor 240 may determine the distance between the main housing section 315 and the roller housing section 320 based on the obtained data in a manner similar to that described below. The sensor 240 may provide information indicative of the distance between the main housing section 315 and the roller housing section 320 to the controller 340.

[0044] Alternatively or additionally, the controller 340 determines the distance between the main housing section 315 and the roller housing section 320 based on the measurement data. In some embodiments, the sensor 240 includes a light emitter 330 and a light receiver 335. The light emitter 330 may be disposed at an end of the main housing section 315 and the light receiver 335 may be disposed at an end of the roller housing section 320 opposite the light emitter 330. In some embodiments, the roller housing section 320 is slidable along the chassis 325 to adjust the size of the visible portion of the rollable display panel 310, as described below with respect to FIG. 4. The light emitter 330 may emit pulses of light that are received by the light receiver 335. The light receiver 335 may provide received light information associated with the light received by the light receiver 335 to the controller 340.

[0045] The received light information may include light wave measurements indicative of one or more characteristics associated with the light received by the receiver 335. For example, the received light information may include information indicative of the amount of light received by the receiver 335, the wavelength of the light waves received by the receiver 335, the frequency of the light waves received by the receiver 335, the amplitude of the light waves received by the receiver 335, etc.

[0046] As indicated by reference numeral 360, the controller 340 measures the distance and / or gap between the light emitter 330 and the light receiver 335 based on the light wave measurements included in the measurement data. The controller 340 may determine the distance between the light emitter 330 and the light receiver 335 based on the received light information. The controller 340 may determine the distance between the main housing section 315 and the roller housing section 320 based on the distance between the light emitter 330 and the light receiver 335. The controller 340 may determine a new size of the visible portion of the rollable display panel 310 based on the distance between the main housing section 315 and the roller housing section 320.

[0047] For example, controller 340 may determine the length of main housing section 315 and / or the length of roller housing section 320 based on accessing a data structure (e.g., a database, table, list, etc.) that stores information indicative of the length of main housing section 315 and / or the length of roller housing section 320. The controller may add the distance between main housing section 315 and roller housing section 320 to the length of main housing section 315 to calculate a dimension (e.g., the length of a side of the visible portion of rollable display panel 310). Controller 340 may calculate the size of the visible portion of rollable display panel 310 based on the length of the side of the visible portion and the length of roller housing section 320. For example, controller 340 may determine the size of the visible portion based on multiplying the length of the side of the visible portion by the length of roller housing section 320.

[0048] In some embodiments, the light emitter 330 is collocated with the light receiver 335 at an end of the main housing section 315. For example, the light emitter 330 and the light receiver 335 may be included in a radar device, a LIDAR device, or the like, disposed at an end of the main housing section 315. The light emitter 330 may emit pulses of light, and the light receiver 335 may receive the light reflected by the roller housing section 320. The controller 340 may receive information indicative of the amount of light emitted by the light emitter 330 and / or the amount of reflected light received by the light receiver 335. The controller 340 may determine a distance between the roller housing section 320 and the end of the main housing section 315 based on the amount of reflected light received by the light receiver 335. The controller 340 may determine a size of the visible portion of the rollable display panel 310 based on the distance between the roller housing section 320 and the end of the main housing section 315. In some embodiments, the controller 340 determines the size of the visible portion of the rollable display panel 310 in the same manner as described above.

[0049] In some aspects, the controller 340 determines an accuracy associated with the adjustment mechanism 345 based on determining a size of the visible portion of the rollable display panel 310. The adjustment mechanism 345 may include a motor, a counter, and a counter element (e.g., the counter 422 and / or the counter element 424 shown in FIG. 4). The counter may receive information from the counter element indicating a number of rotations of the motor. The counter may provide information to the controller 340 indicating the number of rotations. The controller 340 may determine an intended size of the visible portion of the rollable display panel 310 based on the number of rotations of the motor. The controller 340 may determine an accuracy associated with the adjustment mechanism 345 based on comparing the intended size of the visible portion to the size of the visible portion. For example, the controller 340 may determine an accuracy associated with the adjustment mechanism 345 based at least in part on a difference between the intended size of the visible portion and the size of the visible portion.

[0050] In some aspects, the controller 340 determines that the difference between the intended size of the visible portion and the size of the visible portion meets a difference threshold. The controller 340 may determine to recalibrate the adjustment mechanism 345 based on the difference between the intended size of the visible portion and the size of the visible portion meeting the threshold. In some aspects, the controller 340 recalibrates the adjustment mechanism 345 based at least in part on calibrating a counter of the adjustment mechanism 345 to account for the difference between the intended size of the visible portion and the size of the visible portion.

[0051] 3B by reference numeral 365. The display device 305 may configure the output settings of the content to cause the content to be displayed via the visible portion of the rollable display panel 310. For example, the display device 305 may configure dimensions of the displayed content to correspond to dimensions of the visible portion of the rollable display panel 310, an aspect ratio of the displayed content to correspond to an aspect ratio associated with the size of the visible portion of the rollable display panel 310, etc.

[0052] As indicated by reference numeral 370, the display device 305 causes the adjustment mechanism 345 to adjust the visible portion of the rollable display panel 310. In some aspects, the display device 305 (e.g., the controller 340) causes the adjustment mechanism 345 to adjust the visible portion of the rollable display panel 310 based on user input in a manner similar to that described above with respect to FIG.

[0053] Alternatively or additionally, the display device 305 may have the adjustment mechanism 345 adjust the visible portion of the rollable display panel 310 to reduce the risk of damage to the display device 305 (e.g., the rollable display panel 310). In some aspects, the controller 340 determines that the dimensions of the rollable display panel 310 (e.g., the size of the visible portion, the length of a side of the rollable display panel 310, etc.) meet a threshold value.

[0054] The controller 340 may monitor data obtained by another sensor 240 of the user device 110 based on the dimensions of the rollable display panel 310 meeting a threshold. For example, the controller 340 may monitor data obtained by an accelerometer, gyroscope, temperature sensor, etc. to determine if the user device 110 has been dropped, overheated, etc. The controller 340 may cause the adjustment mechanism 345 to reduce the size of the dimensions of the rollable display panel 310 when the data obtained by the other sensor 240 indicates that the user device 110 has been dropped, overheated, etc. In this manner, the controller 340 may reduce the risk of damage to the rollable display panel 310.

[0055] As noted above, Figures 3A and 3B are provided as an example, and other examples may differ from what has been described with respect to Figures 3A and 3B.

[0056] 4 is a diagram illustrating an example 400 relating to managing a rollable display panel of a display device in accordance with the present disclosure. FIG 4 is a top internal view of a display device 305 in an extended state.

[0057] As shown in FIG. 4 , the adjustment mechanism 345 is configured to allow the rollable display panel 310 to extend from and / or retract into the internal housing of the display device 305. The adjustment mechanism 345 may include a first set of slide rails 402, a first set of slide tracks 404, a second set of slide rails 406, a second set of slide tracks 408, and a set of gears 410. The first set of slide rails 402, which may extend from an inner surface of the roller housing section 320, may be configured to be slidably received by the first set of slide tracks 404, which may be provided (e.g., as a slot) within an inner surface of the user device 110. Each of the first set of slide rails 402 may include a first plurality of teeth 412 and a first stop element 414. The first plurality of teeth 412 may be configured to engage with gear teeth 416 of the set of gears 410. In some aspects, the set of gears 410 is provided within a hollow interior of the user device 110. Each of the sets of gears 410 can be configured to rotate about an axis of rotation perpendicular to the side of the user device 110. The first stop element 414 can be configured to prevent the first set of slide rails 402 from separating from the first set of slide tracks 404.

[0058] Similarly, a second set of slide rails 406, which may extend from an inner surface of the roller housing section 320 opposite the inner surface from which the first set of slide rails 402 extend, may be configured to be slidably received by a second set of slide tracks 408. The second set of slide tracks 408 may be provided in a hollow interior of the user device 110. Each of the second set of slide rails 406 may include a second plurality of teeth 418 and a second stop element 420. The second plurality of teeth 418 may be configured to engage with the gear teeth 416 of the set of gears 410. The second stop element 420 may be configured to prevent the second set of slide rails 406 from separating from the second set of slide tracks 408.

[0059] The rollable display panel 310 may be attached to the top surface of the first set of slide rails 402 and / or the second set of slide rails 406. For example, the rollable display panel 310 may be laminated, glued, etc. to the top surface of the first set of slide rails 402 and / or the second set of slide rails 406. The adjustment mechanism 345 may be configured to adjust the position of the first set of slide rails 402 and / or the second set of slide rails 406 by an equal distance within the first set of slide tracks 404 and / or the second set of slide tracks 408, respectively, to uniformly expand and / or contract the rollable display panel 310 from the internal housing of the user device 110. In this manner, the adjustment mechanism 345 may symmetrically expand and / or contract the rollable display panel 310 to change the size of the visible portion of the rollable display panel 310.

[0060] In some embodiments, as shown in FIG. 4, the adjustment mechanism 345 includes a counter 422 and a counter element 424. The counter element 424 may be configured to acquire data associated with the rotation of the set of gears 410 and / or the rollers 426. The rollers 426 may be located inside the roller housing section 320. The rollable display panel 310 may advance around the rollers 426 as the rollable display panel 310 is expanded and / or contracted. The counter element 424 may be configured to determine the number of rotations of the set of gears 410, the number of rotations of the rollers 426, the rotational distance advanced by the set of gears 410, the rotational distance advanced by the rollers 426, the portion of the second plurality of teeth 418 engaged by the gear teeth 416, etc. The counter element 424 may provide the acquired data to the counter 422. The counter 422 may convert the obtained data into information indicative of the number of rotations associated with the set of gears 410, the number of rotations associated with the rollers 426, the size of the rollable display panel 310 extended from and / or retracted into the internal housing of the user device 110, etc. The counter 422 may provide that information to the controller 340 in a manner similar to that described above with respect to Figures 3A and 3B.

[0061] As noted above, Figure 4 is provided as an example. Other examples may differ from those described with respect to Figure 4.

[0062] 5 is a diagram illustrating an example 500 relating to managing a rollable display panel of a display device in accordance with the present disclosure. As shown in FIG. 5, the display device 305 modifies operation of the adjustment mechanism 345 based at least in part on detecting an obstruction that interferes with the movement of the rollable display panel 310 (shown in dashed lines in FIG. 5).

[0063] As shown at reference numeral 502, the display device 305 detects an obstruction (e.g., a user's finger in the path of the rollable display panel 305 as it extends from the internal housing of the user device 110). In some aspects, the sensor 240 includes a light emitter 330 and a light receiver 335. In some aspects, the light emitter 330 is located at an end of the main housing section 315 and the light receiver 335 is located on the roller housing section 320 in a manner similar to that described above.

[0064] The sensor 240 may detect an obstacle based on the amount of light received by the receiver 335. For example, the sensor 240 may determine that the amount of light received by the receiver 335 meets a threshold (e.g., is less than a threshold amount of light). The sensor 240 may detect an obstacle based on the amount of light received by the receiver 335 meeting the threshold.

[0065] In some embodiments, the light receiver 335 is collocated with the light emitter 330. For example, the light emitter 330 and the light receiver 335 may be disposed at an end of the main housing section 315 in a manner similar to that described above. The sensor 240 may detect the object based on the amount of light received by the light receiver 335. For example, the light emitter 330 and the light receiver 335 may be included in a LIDAR device. The light emitter 330 may emit pulses of light. The light receiver 335 may receive light reflected by the object. The sensor 240 may detect the object based on light reflected from the object and received by the light receiver 335.

[0066] In some embodiments, the sensor 240 determines distance data indicative of the location of the detected object based on the light and / or reflected light received by the optical receiver 335. In some embodiments, the sensor 240 determines distance data indicative of the location of the detected object in a manner similar to that described above with respect to FIG.

[0067] The sensor 240 may provide distance data to the controller 340. The controller may determine a location of the detected object relative to content displayed via the rollable display panel 310, an edge of the rollable display panel 310, the light emitters 330, etc. The controller may determine an adjusted size of the visible portion of the rollable display panel 310 based on the location of the detected object. The adjusted size of the visible portion may prevent the roller housing section 320 from contacting the detected object. For example, the adjusted size of the visible portion may correspond to a location of the roller housing section 320 closer to an edge of the main housing section 315 relative to the location of the detected object.

[0068] As indicated by reference numeral 504, the display device 305 (e.g., the controller 340) adjusts output settings according to the location of the obstruction (e.g., the location of the detected object). In some aspects, the controller 340 configures output settings of the displayed content based on the adjusted size of the visible portion of the rollable display panel 310. In some aspects, the output settings are configured to substantially align edges of the displayed content and / or edges of the rollable display panel 310 with the location of the detected object.

[0069] As noted above, Figure 5 is provided as an example. Other examples may differ from those described with respect to Figure 5.
