[0024] Figure 12 is a schematic diagram of an exemplary AI system.

[0025] Figure 1 illustrates an exemplary head-worn electronic device.

[0026] Referring to FIG. 1, a head-worn electronic device (100) may include a head-worn housing structure (110). The head-worn housing structure (110) may at least partially enclose at least a portion of one or more components of the head-worn electronic device (100) (as exemplified in the description of FIG. 3) for protection from debris and other degrading forces external to the head-worn electronic device (100). The head-worn housing structure (110) may include an eye frame (111), a left temple frame (112) extending from the eye frame (111), and a right temple frame (113) extending from the eye frame (111). For example, the head-worn housing structure (110) may be configured such that, when worn by a user (190), the eye frame (111) is positioned in front of the eyes (or at least one eye) of the user's (190) head, the left temple frame (112) is held against the left surface of the user's (190) head, and the right temple frame (113) is held against the right surface of the user's (190) head.

[0027] A head-worn electronic device (100) may include a display assembly (120). The display assembly (120) may be arranged relative to a head-worn structure (110) (or an eye frame (111)). The display assembly (120) may include a first display panel (121) positioned over a left eye of a user (190) wearing the head-worn structure (110) and a second display panel (122) positioned over a right eye of the user (190) wearing the head-worn structure (110). Each of the first display panel (121) and the second display panel (122) may include any suitable type of display for presenting visual data to a user wearing the head-worn structure (110) using visible light. As a non-limiting example, the first display panel (121) and the second display panel (122) may be usable (or configured) to display visual content as two separate images (e.g., including a first image and a second image) such that the visual content is displayed as a stereoscopic image. For example, the first image may be displayed on the first display panel (121) and the second image may be displayed on the second display panel (122). The head-worn electronic device (100) may include a display driving circuit used to display the first image on the first display panel (121) and to display the second image on the second display panel (122). As a non-limiting example, the display driving circuit may include a first display driving circuit for the first display panel (121) and a second display driving circuit for the second display panel (122).

[0028] FIG. 2 is a chart illustrating an exemplary method for reducing motion blur on a display panel.

[0029] Referring to FIG. 2, the head-worn electronic device (100) can at least partially change images displayed on each of the display panels (e.g., the first display panel (121) and the second display panel (122)) according to the movement of the head-worn electronic device (100) worn by the user (190). For example, when the speed of the motion of the head-worn electronic device (100) that causes the at least partial change of the images is not synchronized with the speed of displaying the images, motion blur may occur with respect to the display panels. The motion blur may cause motion sickness in the user (190) viewing the display panels.

[0030] For example, in order to reduce the motion blur, the length of the time interval between the emission periods of each of the light-emitting elements within each of the display panels of the head-worn electronic device (100) may be set relatively long. This setting may be expressed as in the chart (200).

[0031] The horizontal axis of the chart (200) represents time, and the vertical axis of the chart (200) represents peak brightness.

[0032] For example, the head-worn electronic device (100) can control each of the display panels to emit light during at least a portion of a time interval corresponding to a light emission period. For example, the head-worn electronic device (100) can control each of the display panels to emit light according to a duty cycle (or on duty) corresponding to a ratio of the length of at least a portion of the time interval to the length of the light emission period. For example, the head-worn electronic device (100) can control each of the display panels to emit light with a peak luminance L within a light emission period (211) that is at least a portion of a time interval (210) corresponding to the light emission period. For example, the head-worn electronic device (100) can emit light with a peak luminance L according to a duty cycle corresponding to a ratio of the length of the light emission period (211) to the length of the time interval (210). For example, the head-worn electronic device (100) can control each of the display panels to emit light with a peak luminance L within a light-emitting section (221) that is at least a portion of a time section (220) corresponding to the light-emitting cycle (e.g., after the time section (210). For example, the head-worn electronic device (100) can emit light with a peak luminance L according to a duty cycle corresponding to a ratio of a length of the light-emitting section (221) to a length of the time section (220).

[0033] For example, the motion blur can be reduced depending on the time interval (230) during which light is not emitted (or light is stopped from being emitted) (e.g., between the emission interval (211) and the emission interval (221). As a non-limiting example, as the length of the time interval (230) increases, the probability of occurrence of the motion blur can decrease. Increasing the length of the time interval (230) decreases the probability of occurrence of the motion blur, but increasing the length of the time interval (230) can decrease the luminous power per unit time of each of the display panels. For example, since the length of the emission interval (211) (or the length of the emission interval (221)) becomes shorter as the length of the time interval (230) increases, increasing the length of the time interval (230) can decrease the luminous power of each of the display panels. For example, increasing the length of the time interval (230) reduces the probability of motion blur occurring, but increasing the length of the time interval (230) may reduce the brightness level of each of the display panels.

[0034] For example, increasing the peak luminance L may be used to compensate for the brightness level of each of the display panels decreasing as the length of the time interval (230) increases. Increasing the peak luminance L may increase the brightness level of each of the display panels, but as the peak luminance L increases, the lifespan of each of the light-emitting elements within each of the display panels may decrease. For example, increasing the peak luminance L may increase the brightness level of each of the display panels, but as the peak luminance L increases, burn-in of the light-emitting elements (e.g., organic light emitting diodes (OLEDs)) within each of the display panels may occur.

[0035] The head-worn electronic device (100) described below can change (or switch) from emitting light with a first peak luminance according to a first duty cycle to emitting light with a second peak luminance higher than the first peak luminance according to a second duty cycle that is lower than the first duty cycle, and / or change (or switch) from emitting light with the second peak luminance according to the second duty cycle to emitting light with the first peak luminance according to the first duty cycle. For example, the head-worn electronic device (100) can reduce the occurrence of motion blur through this operation. For example, the head-worn electronic device (100) can relatively lengthen the lifespan of each of the light-emitting elements within each of the display panels through this operation.

[0036] Figure 3 is a schematic diagram of an exemplary head-worn electronic device.

[0037] Referring to FIG. 3, a head-worn electronic device (100) may include at least one processor (310), a memory (320), a display assembly (120), one or more first sensors (341), one or more second sensors (342), and one or more third sensors (343). The display assembly (120) may include a display driving circuit (331) and display panels (332).

[0038] At least one processor (310) may include any processing circuitry operative to control the performance and operations of one or more assemblies (e.g., display assembly (120)) of the head-worn electronic device (100). For example, at least one processor (310) may include a central processing unit (CPU) (e.g., including processing circuitry). For example, at least one processor (310) may include a graphics processing unit (GPU) (e.g., including processing circuitry) used to generate (or obtain) an image to be displayed on each of the display panels (332). For example, at least one processor (310) may include a display processing unit (DPU) (e.g., including processing circuitry) used to transmit data for an image to be displayed on each of the display panels (332). For example, at least one processor (310) may include an image signal processor (ISP) (e.g., including processing circuitry) used to process images acquired via a camera (e.g., one or more second sensors (342) and / or one or more third sensors (343)) of the head-worn electronic device (100). For example, at least one processor (310) may include a sensor interface (or sensor hub) (e.g., including processing circuitry) used to process sensing data acquired via one or more first sensors (341).

[0039] For example, at least one processor (310) may be implemented as a single chip or a single chipset, such as a system on chip (SoC). For example, at least one processor (310) may also be implemented as multiple chips or multiple chipsets. As a non-limiting example, a chip (or chipset) within the head-worn electronic device (100) that includes the sensor interface of at least one processor (310) may be separated from a chip (or chipset) (e.g., which may further include a GPU and / or a DPU) within the head-worn electronic device (100) that includes the CPU of at least one processor (310). For example, a chip (or chipset) within the head-worn electronic device (100) that includes the sensor interface of at least one processor (310) may be adjacent to one or more first sensors (341).

[0040] For example, at least one processor (310) may be used to execute or run one or more software applications, such as an operating system software application, a firmware software application, a media playback software application, a media editing software application, and / or any other suitable software applications.

[0041] The memory (320) may include one or more storage media. For example, the one or more storage media may include a hard drive, flash memory, permanent memory such as read-only memory (ROM), semi-permanent memory such as random access memory (RAM), any other suitable type of storage assembly, or any combination thereof. The memory (320) may include a cache memory, which is one or more different types of memory used to temporarily store data for the function or feature of the head-mounted electronic device (100). The memory (320) may be fixedly embedded within the head-worn electronic device (100) or incorporated into one or more suitable types of components (e.g., a subscriber identity module (SIM) card and / or a secure digital (SD) memory card) that can be repeatedly inserted into and removed from the head-worn electronic device (100).

[0042] The memory (320) may store one or more software applications, such as an operating system software application, a firmware software application, a media playback software application, a media editing software application, and / or any other suitable software applications. For example, the one or more software applications may include instructions executable by at least a portion of at least one processor (310).

[0043] The display assembly (120) may include any suitable circuit for displaying visual data (or visual information) generated or acquired by at least one processor (310) with visible light. The display assembly (120) may include display panels (332) including a first display panel (121) positioned above the left eye of a user (190) wearing the head-worn housing structure (110) and a second display panel (122) positioned above the right eye of the user wearing the head-worn housing structure (110). The first display panel (121) may include pixels. Each of the pixels in the first display panel (121) may include first sub-pixels. As a non-limiting example, the first sub-pixels may include a set of sub-pixels for emitting red light, a set of sub-pixels for emitting green light, a set of sub-pixels for emitting blue light, and / or sub-pixels for emitting white light. For example, each of the first sub-pixels may include a first light-emitting element (e.g., an organic light emitting diode (OLED), an OLED on silicon (OLEDoS), a micro LED, an LED on silicon (LEDoS), a liquid crystal display (LCD), or a liquid crystal on silicon (LCoS)) for emitting light and / or a color filter. The second display panel (122) may include pixels. Each of the pixels in the second display panel (122) may include second sub-pixels. As a non-limiting example, the second sub-pixels may include a set of sub-pixels for emitting red light, a set of sub-pixels for emitting green light, a set of sub-pixels for emitting blue light, and / or sub-pixels for emitting white light.For example, each of the second sub-pixels may include a second light-emitting element (e.g., OLED, OLEDoS, micro LED, LEDoS, LCD, or LCoS) for emitting light and / or a color filter.

[0044] The display driver circuit (331) (display driver circuitry or display driver integrated circuitry) within the display assembly (120) can control pixels within each of the display panels (332) to emit light through each of the display panels (332). As a non-limiting example, the display driver circuit (331) can include a first display driver circuit (not shown) connected to a first display panel (121) and a second display driver circuit (not shown) connected to a second display panel (122).

[0045] The display driving circuit (331) may be used to display visual information (e.g., data or information regarding the first image as exemplified in the description of FIG. 1) transmitted from at least one processor (310) on the first display panel (121). For example, the display driving circuit (331) may be configured to control the first display panel (121) for displaying the visual information. As a non-limiting example, the visual information may be transmitted to the display driving circuit (331) from the CPU within the at least one processor (310) via the DPU within the at least one processor (310). For example, the display driving circuit (331) may control the first display panel (121) under the control of the at least one processor (310). For example, the display driving circuit (331) may control the first display panel (121) according to a command received from the at least one processor (310). For example, the display driving circuit (332) can control the second display panel (122) under the control of at least one processor (310). For example, the display driving circuit (332) can control the second display panel (122) according to a command received from at least one processor (310).

[0046] One or more first sensors (341) may be used to identify the motion of the head-worn electronic device (100) (or the motion of the head-worn structure (110)). For example, the one or more first sensors (341) may include an acceleration sensor. For example, the one or more first sensors (341) may include a gyroscope sensor. For example, the one or more first sensors (341) may include a geomagnetic sensor. For example, the one or more first sensors (341) may be described as an inertial measurement unit (IMU) sensor. For example, the one or more first sensors (341) may provide sensing data regarding the motion of the head-worn electronic device (100) to at least one processor (310). For example, the movement of the head-worn electronic device (100) can be identified by at least one processor (310) using the sensing data.

[0047] One or more second sensors (342) may be used to track the gaze of the eyes of a user (190) wearing the head-mounted electronic device (100). For example, the one or more second sensors (342) may include one or more cameras (or one or more image sensors) directed toward the eyes of the user (190). For example, the one or more second sensors (342) may include a light-emitting circuit that emits light toward the eyes of the user (190). For example, the one or more second sensors (342) may provide sensing data regarding the gaze to at least one processor (310). For example, the gaze may be tracked by the at least one processor (310) using the sensing data.

[0048] One or more third sensors (343) may be used to acquire an image representing a scene around the head-worn electronic device (100) (e.g., a scene in front of the head-worn electronic device (100). For example, the one or more third sensors (343) may include one or more cameras facing in a direction corresponding to the direction of the user's eyes. As a non-limiting example, a field of view (FOV) of one or more of the one or more cameras may correspond to the FOV of the user's eyes. For example, the one or more third sensors (343) may provide an image of the scene to at least one processor (310).

[0049] As a non-limiting example, the head-worn electronic device (100) may be an AR glass device, unlike the illustration in FIG. 1. As an example, the display panels (332), including the first display panel (121) and the second display panel (122), and a portion of the head-worn structure (110) may be (substantially) transparent, such that a scene in front of the head-worn electronic device (100) is visible.

[0050] At least one processor (310) may control each of the display panels (332) to emit light at a first peak brightness according to a first duty cycle to maintain the quality (e.g., lifespan) of a light-emitting element included in each of the display panels (332). At least one processor (310) may control each of the display panels (332) to emit light at a second peak brightness higher than the first peak brightness according to a second duty cycle lower than the first duty cycle to reduce motion blur. Emitting light at the first peak brightness according to the first duty cycle and emitting light at the second peak brightness according to the second duty cycle are described with reference to FIG. 4.

[0051] FIG. 4 illustrates an exemplary method of emitting light with a first peak brightness according to a first duty cycle and an exemplary method of emitting light with a second peak brightness according to a second duty cycle.

[0052] Referring to Fig. 4, the horizontal axis of the chart (400) represents time, and the vertical axis of the chart (400) represents peak luminance. The horizontal axis of the chart (450) represents time, and the vertical axis of the chart (450) represents peak luminance.

[0053] As illustrated by the chart (400), at least one processor (310) can control each of the display panels (332) to emit light with the first peak luminance, peak luminance L1, within a light emission period (411), which is a portion of a time period (410) corresponding to a light emission cycle. For example, the at least one processor (310) can control each of the display panels (332) to emit light with the peak luminance L1 according to the first duty cycle, which corresponds to a ratio of the length of the time period (410) to the length of the light emission period (411). For example, the at least one processor (310) can control each of the display panels (332) to emit light with the peak luminance L1 according to the first duty cycle by transmitting one or more first commands to the display driving circuit (331) to emit light with the peak luminance L1 according to the first duty cycle.

[0054] As represented by the chart (450), at least one processor (310) can control each of the display panels (332) to emit light with the second peak luminance, peak luminance L2, within a light emission period (461), which is a part of a time period (460) corresponding to a light emission cycle. The length of the time period (460) can be the same as the length of the time period (410). For example, at least one processor (310) can control each of the display panels (332) to emit light with the peak luminance L2 according to the second duty cycle corresponding to a ratio of the length of the time period (460) to the length of the light emission period (461). For example, at least one processor (310) can control each of the display panels (332) to emit light at a peak luminance L2 according to the second duty cycle by transmitting one or more second commands to the display driving circuit (331) to emit light at a peak luminance L2 according to the second duty cycle.

[0055] For example, the luminous power per unit time caused by emitting light with peak luminance L1 according to the first duty cycle may correspond to the size of the area (420) within the chart (400). For example, the luminous power per unit time caused by emitting light with peak luminance L2 according to the second duty cycle may correspond to the size of the area (470) within the chart (450). For example, the brightness level of the display panels (332) provided by emitting light with peak luminance L1 according to the first duty cycle may correspond to the size of the area (420) within the chart (400). For example, the brightness level of the display panels (332) provided by emitting light with peak luminance L2 according to the second duty cycle may correspond to the size of the area (470) within the chart (450).

[0056] At least one processor (310) may identify whether a first state of the head-worn electronic device (100) in which the probability of occurrence of motion blur increases is detected while emitting light with peak luminance L1 according to the first duty cycle. For example, the at least one processor (310) may identify, through one or more first sensors (341), whether a movement of the head-worn electronic device (100) outside a threshold range is detected while emitting light with peak luminance L1 according to the first duty cycle. For example, the at least one processor (310) may identify, through one or more second sensors (342), whether a gaze movement speed faster than a reference movement speed (e.g., a gaze of an eye of a user wearing the head-worn electronic device (100)) is detected while emitting light with peak luminance L1 according to the first duty cycle. For example, at least one processor (310) can identify whether a movement speed of visual content (e.g., provided by an image (or images) generated by the at least one processor (310)) that is faster than a threshold movement speed is detected (e.g., provided by an image (or images) displayed on each of the display panels (332)) while emitting light with a peak luminance L1 according to the first duty cycle.

[0057] At least one processor (310) may control each of the display panels (332) to emit light with a peak luminance L2 according to the second duty cycle based on the first state of the head-worn electronic device (100) detected while emitting light with a peak luminance L1 according to the first duty cycle. For example, at least one processor (310) may control each of the display panels (332) to stop emitting light with a peak luminance L1 according to the first duty cycle based on the first state of the head-worn electronic device (100) detected while emitting light with a peak luminance L1 according to the first duty cycle. For example, at least one processor (310) may transmit the one or more second commands to the display driving circuit (331) based on the first state of the head-worn electronic device (100) detected while emitting light with peak luminance L1 according to the first duty cycle.

[0058] For example, a change in the brightness of the display panels (332) perceived by the user (190) from emitting light at a peak luminance L1 according to the first duty cycle to emitting light at a peak luminance L2 according to the second duty cycle may reduce the visual quality of the display panels (332). As a non-limiting example, emitting light at a peak luminance L2 according to the second duty cycle may be performed (or executed) to reduce motion blur, reduce dragging caused on the screen, and / or reduce the likelihood of motion sickness (e.g., virtual reality (VR) sickness) occurring to a user viewing the display panels (332). For example, the amount of light per unit time caused by emitting light with peak brightness L2 according to the second duty cycle after (or immediately after) the first state of the head-worn electronic device (100) may correspond to the amount of light per unit time caused by emitting light with peak brightness L1 according to the first duty cycle before (or immediately before) the first state of the head-worn electronic device (100) to maintain the brightness of the display panels (332) perceived by the user (190). For example, at least one processor (310) may determine the second duty cycle (or length of the light-emitting period (461)) and peak luminance L2 based on detection of the first state of the head-worn electronic device (100) such that the amount of light per unit time after (or immediately after) the first state of the head-worn electronic device (100) corresponds to the amount of light per unit time before (or immediately before) the first state of the head-worn electronic device (100). For example, the size of the region (470) may be substantially the same as the size of the region (420).

[0059] At least one processor (310) may identify whether a second state of the head-worn electronic device (100) in which the probability of occurrence of motion blur decreases is detected while emitting light with peak luminance L2 according to the second duty cycle. For example, the at least one processor (310) may identify, through one or more first sensors (341), whether movement of the head-worn electronic device (100) within the threshold range is detected while emitting light with peak luminance L2 according to the second duty cycle. For example, the at least one processor (310) may identify, through one or more second sensors (342), whether a movement speed of a gaze (e.g., a gaze of an eye of a user wearing the head-worn electronic device (100)) slower than the reference movement speed is detected while emitting light with peak luminance L2 according to the second duty cycle. For example, at least one processor (310) can identify whether a movement speed of visual content (e.g., provided by an image (or images) generated by the at least one processor (310)) that is slower than the threshold movement speed is detected (e.g., provided by an image (or images) displayed on each of the display panels (332)) while emitting light with a peak luminance L2 according to the second duty cycle.

[0060] At least one processor (310) may control each of the display panels (332) to emit light with a peak luminance L1 according to the first duty cycle based on the second state of the head-worn electronic device (100) detected while emitting light with a peak luminance L2 according to the second duty cycle. For example, at least one processor (310) may control each of the display panels (332) to stop emitting light with a peak luminance L2 according to the second duty cycle based on the second state of the head-worn electronic device (100) detected while emitting light with a peak luminance L2 according to the second duty cycle. For example, at least one processor (310) may transmit the one or more first commands to the display driving circuit (331) based on the second state of the head-worn electronic device (100) detected while emitting light with peak luminance L2 according to the second duty cycle.

[0061] For example, a change in the brightness of the display panels (332) perceived by the user (190) from emitting light at a peak brightness L2 according to the second duty cycle to emitting light at a peak brightness L1 according to the first duty cycle may reduce the visual quality of the display panels (332). For example, emitting light at a peak brightness L1 according to the first duty cycle may be performed (or executed) to extend the life of light-emitting elements (e.g., OLEDs) within the display panels (332). For example, the amount of light per unit time caused by emitting light with peak luminance L1 according to the first duty cycle after (or immediately after) the second state of the head-worn electronic device (100) may correspond to the amount of light per unit time caused by emitting light with peak luminance L2 according to the second duty cycle before (or immediately before) the second state of the head-worn electronic device (100) to maintain the brightness of the display panels (332) perceived by the user (190). For example, at least one processor (310) may determine the first duty cycle (or length of the light-emitting period (411)) and peak luminance L1 based on detection of the second state of the head-worn electronic device (100) such that the amount of light per unit time after (or immediately after) the second state of the head-worn electronic device (100) corresponds to the amount of light per unit time before (or immediately before) the second state of the head-worn electronic device (100). For example, the size of the region (420) may be substantially the same as the size of the region (470).

[0062] For example, even if the amount of light per unit time caused by emitting light with peak luminance L1 according to the first duty cycle after (or immediately after) the second state of the head-worn electronic device (100) corresponds to the amount of light per unit time caused by emitting light with peak luminance L2 according to the second duty cycle, the first characteristic of the light emitted with peak luminance L1 according to the first duty cycle may be different from the second characteristic of the light emitted with peak luminance L2 according to the second duty cycle. For example, at least one processor (210) may control the display assembly (120) to perform (or execute) gamma adjustment (or color adjustment) to reduce the difference between the first characteristic and the second characteristic. For example, at least one processor (210) may control the display assembly (120) to perform the gamma adjustment by transmitting one or more commands for the gamma adjustment to the display driving circuit (331).

[0063] As a non-limiting example, the image displayed on each of the display panels (332) may be maintained independently of the change from emitting light with a peak luminance L2 according to the second duty cycle to emitting light with a peak luminance L1 according to the first duty cycle, depending on the execution state of the at least one processor (310). For example, the at least one processor (310) may adjust a data voltage used to emit light with a peak luminance L1 according to the first duty cycle, independently of the image maintained on each of the display panels (332) before and after detection of the second state of the head-worn electronic device (100). For example, a data voltage applied to a subpixel within each of the display panels (332) to emit light with a peak luminance L1 according to the first duty cycle after detection of the second state of the head-worn electronic device (100) may be different from a data voltage applied to a subpixel within each of the display panels (332) to emit light with a peak luminance L2 according to the second duty cycle before detection of the second state of the head-worn electronic device (100), independently of the image maintained on each of the display panels (332) before and after detection of the second state of the electronic device (100), depending on the adjustment. For example, at least one processor (310) may control the display panels (332) to adjust the data voltage using second reference gamma data that is different from the first reference gamma data used to identify the data voltage corresponding to an image to be displayed on each of the display panels (332) based on emitting light with a peak luminance L2 according to the second duty cycle prior to detection of the second state of the head-worn electronic device (100).

[0064] As a non-limiting example, an image displayed on each of the display panels (332) may be maintained independently of a change from emitting light with a peak luminance L1 according to the first duty cycle to emitting light with a peak luminance L2 according to the second duty cycle, depending on the execution state of the at least one processor (310). For example, the at least one processor (310) may adjust a data voltage used to emit light with a peak luminance L2 according to the second duty cycle, independently of the image maintained on each of the display panels (332) before and after detection of the first state of the head-worn electronic device (100). For example, a data voltage applied to a subpixel within each of the display panels (332) to emit light with a peak luminance L2 according to the second duty cycle after detection of the first state of the head-worn electronic device (100) may be different from a data voltage applied to a subpixel within each of the display panels (332) to emit light with a peak luminance L1 according to the first duty cycle before detection of the first state of the head-worn electronic device (100), independently of the image maintained on each of the display panels (332) before and after detection of the first state of the electronic device (100), depending on the adjustment. For example, at least one processor (310) may control the display panels (332) to adjust the data voltage using the first reference gamma data that is different from the second reference gamma data used to identify the data voltage corresponding to the image displayed on each of the display panels (332) based on emitting light with a peak luminance L1 according to the first duty cycle prior to detection of the first state of the head-worn electronic device (100).

[0065] As a non-limiting example, directly switching (or changing) from emitting light at a peak luminance L1 according to the first duty cycle to emitting light at a peak luminance L2 according to the second duty cycle may cause flickering on the display panels (332). As a non-limiting example, directly switching (or changing) from emitting light at a peak luminance L2 according to the second duty cycle to emitting light at a peak luminance L1 according to the first duty cycle may cause flickering on the display panels (332). For example, at least one processor (310) may control the display assembly (120) to perform operations to reduce the flicker. The operations are described with reference to FIGS. 5 and 6.

[0066] Figures 5 and 6 illustrate an exemplary method of changing from emitting light with a first peak brightness according to a first duty cycle to emitting light with a second peak brightness according to a second duty cycle.

[0067] Referring to FIG. 5, the horizontal axis of the chart (500) represents time, and the vertical axis of the chart (500) represents duty cycle. The horizontal axis of the chart (550) represents time, and the vertical axis of the chart (550) represents peak brightness.

[0068] At least one processor (310) can control the display panels (332) to emit light with a first peak luminance L1 according to the first duty cycle, duty cycle D1, as represented by each of the charts (500) and (550). For example, at least one processor (310) can detect the first state of the head-worn electronic device (100) at a timing (501) within each of the charts (500) and (550) while emitting light with the first peak luminance L1 according to the first duty cycle, duty cycle D1. For example, at least one processor (310) can, in response to the detection at timing (501), directly change from emitting light with a peak luminance L1 according to a duty cycle D1 to emitting light with a peak luminance L3 according to a duty cycle D3, as represented by charts (500) and (550). As a non-limiting example, the duty cycle D3 can be a value between duty cycles D1 and D2 at which the probability of flickering occurring upon the change is relatively low. As a non-limiting example, the peak luminance L3 can be a value between peak luminance L1 and peak luminance L2 at which the probability of flickering occurring upon the change is relatively low. As a non-limiting example, the duty cycle D3 can be described as an intermediate duty cycle, and the peak luminance L3 can be described as an intermediate peak luminance. As a non-limiting example, at least one processor (310) can directly change from emitting light with a peak luminance L1 according to a duty cycle D1 to emitting light with a peak luminance L3 according to a duty cycle D3 to enhance the responsiveness of the head-worn electronic device (100) to the detection of the first state.

[0069] For example, at least one processor (310) can control each of the display panels (332) to gradually change from emitting light with a peak brightness L3 according to a duty cycle D3 to emitting light with a peak brightness L2 according to a duty cycle D2 within (or during) a time period (502) after the direct change in timing (501). For example, within the time period (502), the duty cycle for emitting light can be gradually changed (or decreased) from a duty cycle D3 to a duty cycle D2, as shown by the chart (500), under the control of the at least one processor (310). For example, within a time period (502), the peak luminance of light emitted through the display panels (332) may be gradually changed (or increased) from peak luminance L3 to peak luminance L2, as indicated by the chart (550), under the control of at least one processor (310).

[0070] For example, at least one processor (310) can control the display panels (332) to emit light with a peak brightness L2 according to a duty cycle D2, as represented by charts (500) and (550), at a timing (503) after a time period (502) from timing (501).

[0071] Referring to Fig. 6, the horizontal axis of the chart (600) represents time, and the vertical axis of the chart (600) represents duty cycle. The horizontal axis of the chart (650) represents time, and the vertical axis of the chart (650) represents peak brightness.

[0072] At least one processor (310) can control the display panels (332) to emit light with a first peak luminance L1 according to the first duty cycle, duty cycle D1, as represented by each of the charts (600) and (650). For example, at least one processor (310) can detect the first state of the head-worn electronic device (100) at a timing (601) within each of the charts (600) and (650) while emitting light with the first peak luminance L1 according to the first duty cycle, duty cycle D1. For example, at least one processor (310) may, in response to the detection at timing (601), control each of the display panels (332) to gradually change from emitting light with a peak luminance L1 according to a duty cycle D1 to emitting light with a peak luminance L2 according to a duty cycle D2 within (or during) a time period (602). For example, within the time period (602), the duty cycle for emitting light may be gradually changed (or decreased) from a duty cycle D1 to a duty cycle D2, as represented by the chart (600), under the control of the at least one processor (310). For example, within a time period (602), the peak luminance of light emitted through the display panels (332) may be gradually changed (or increased) from peak luminance L1 to peak luminance L2, as represented by the chart (650), under the control of at least one processor (310).

[0073] The gradual change in duty cycle represented by chart (500) of Fig. 5 being continuous and the gradual change in peak brightness represented by chart (550) of Fig. 5 being continuous are for convenience of explanation. The gradual change in duty cycle and the gradual change in peak brightness may be performed discontinuously.

[0074] As a non-limiting example, motion blur on the display panels (332) may be more visible when the brightness level of the display panels (332) is relatively low. For example, since the motion blur may be noticeable to the user (190) when the brightness level of the display panels (332) is relatively low, and may be unnoticeable to the user (190) when the brightness level of the display panels (332) is relatively high, at least one processor (310) may decrease the maximum value of the duty cycle used to emit light as the brightness of the display panels (332) is lower. For example, the range over which the duty cycle is changed depending on the first state of the head-worn electronic device (100) (or the second state of the head-worn electronic device (100)) may vary depending on the brightness level of the display panels (332). For example, when the brightness level of the display panels (332) is a first brightness level, the duty cycle D2 to be changed from the duty cycle D1 may be determined as one of the values ​​between a value a (e.g., 10%) and a value b (e.g., 30%). For example, when the brightness level of the display panels (332) is a second brightness level higher than the first brightness level, the duty cycle D2 to be changed from the duty cycle D1 may be determined as one of the values ​​between a value a (e.g., 10%) and a value c (e.g., higher than the value b) (e.g., 50%).

[0075] For example, at least one processor (310) may identify one of the values ​​within a first reference range as the duty cycle D2 based on detection of the first state of the head-worn electronic device (100) performed while the brightness level of the display panels (332) is a first brightness level lower than the reference brightness level. For example, at least one processor (310) may identify one of the values ​​within a second reference range wider than the first reference range as the duty cycle D2 based on detection of the first state of the head-worn electronic device (100) performed while the brightness level of the display panels (332) is a second brightness level higher than the reference brightness level. As a non-limiting example, the difference between duty cycle D1 and duty cycle D2 when the brightness level of the display panels (332) is the first brightness level may be smaller than the difference between duty cycle D1 and duty cycle D2 when the brightness level of the display panels (332) is the second brightness level higher than the first brightness level.

[0076] As a non-limiting example, motion blur on the display panels (332) may be more visible when the refresh rate of the display panels (332) is relatively low. For example, since the motion blur may be noticeable to the user (190) when the refresh rate of the display panels (332) is relatively low and may be unnoticeable to the user (190) when the refresh rate of the display panels (332) is relatively high, at least one processor (310) may decrease the maximum value of the duty cycle used to emit light as the refresh rate of the display panels (332) is lower. For example, the range of changing the duty cycle depending on the first state of the head-worn electronic device (100) (or the second state of the head-worn electronic device (100)) may vary depending on the refresh rate of the display panels (332). For example, when the refresh rate of the display panels (332) is the first refresh rate, the duty cycle D2 to be changed from the duty cycle D1 may be determined as one of the values ​​between a value a (e.g., 10%) and a value b (e.g., 30%). For example, when the refresh rate of the display panels (332) is the second refresh rate higher than the first refresh rate, the duty cycle D2 to be changed from the duty cycle D1 may be determined as one of the values ​​between a value a (e.g., 10%) and a value c (e.g., higher than value b) (e.g., 50%).

[0077] For example, at least one processor (310) may identify one of the values ​​within a first reference range as the duty cycle D2 based on detection of the first state of the head-worn electronic device (100) performed while the refresh rate of the display panels (332) is a first refresh rate lower than the reference refresh rate. For example, at least one processor (310) may identify one of the values ​​within a second reference range wider than the first reference range as the duty cycle D2 based on detection of the first state of the head-worn electronic device (100) performed while the refresh rate of the display panels (332) is a second refresh rate higher than the reference refresh rate. As a non-limiting example, the difference between the duty cycle D1 and the duty cycle D2 when the refresh rate of the display panels (332) is the first refresh rate may be smaller than the difference between the duty cycle D1 and the duty cycle D2 when the refresh rate of the display panels (332) is the second refresh rate higher than the first refresh rate.

[0078] As a non-limiting example, since the user (190) is less sensitive to motion blur at relatively high refresh rates of the display panels (332), the at least one processor (310) may change the refresh rate of the display panels (332) based on detecting the first state of the head-worn electronic device (100) (or detecting the second state of the head-worn electronic device (100). For example, the at least one processor (310) may further control the display assembly (120) to change the refresh rate of the display panels (332) from the first refresh rate to a higher second refresh rate based on the first state of the head-worn electronic device (100) detected while emitting light with peak luminance L1 according to a duty cycle D1. For example, at least one processor (310) can further control the display assembly (120) to change the refresh rate of the display panels (332) from the second refresh rate to the first refresh rate based on the second state of the head-worn electronic device (100) detected while emitting light with peak luminance L2 according to a duty cycle D2.

[0079] As a non-limiting example, at least one processor (310) may determine a duty cycle for emitting light through each of the display panels (332) and a peak luminance of light to be emitted through each of the display panels (332) depending on the display mode.

[0080] For example, at least one processor (310) may control each of the display panels (332) to emit light with a peak luminance L1 according to a duty cycle D1, based on the head-worn electronic device (100) operating in a first display mode. The first display mode may be described as a display mode that maintains an image displayed on the display panels (332) independently of the movement of the head-worn electronic device (100). For example, the first display mode may be described as a mode that displays a background image on most of the display area of ​​each of the display panels (332). For example, within the first display mode, the display assembly (120) may be operating in a state for lower power consumption. For example, the first display mode may be described as an always on display (AoD) mode or an AoD state.

[0081] For example, at least one processor (310) may control each of the display panels (332) to emit light with a peak luminance L2 according to a duty cycle D2, based on the head-worn electronic device (100) operating in a second display mode. The second display mode may be described as a display mode that changes an image displayed on the display panels (332) according to the movement of the head-worn electronic device (100). For example, the second display mode may be described as a mode that displays one or more visual objects that are movable on most of the display area of ​​each of the display panels (332). For example, within the second display mode, the display assembly (120) may be displaying an image representing a scene in front of the head-worn electronic device (100), which is acquired through one or more third sensors (343). For example, the second display mode may be described as a PT (pass-through) mode or PT state.

[0082] As a non-limiting example, the head-worn electronic device (100) (e.g., AR glasses) may be in a state where a relatively high brightness level of the display panels (332) is required. For example, when the illuminance around the head-worn electronic device (100) is relatively high (or when a setting where the brightness level of the display panels (332) is higher than a threshold brightness level is enabled), at least one processor (310) may maintain a peak luminance of light emitted through each of the display panels (332) and change a duty cycle for emitting light through each of the display panels (332). As a non-limiting example, at least one processor (310) may control each of the display panels (332) to emit light at peak luminance L2 according to a duty cycle D1 under a condition where the illuminance is higher than a threshold illuminance, based on the second state of the head-worn electronic device (100) detected while emitting light at peak luminance L2 according to a duty cycle D2.

[0083] As a non-limiting example, a driving voltage (e.g., VSS and / or VDD) applied to the display assembly (120) (or the display panels (332)) for duty cycle D1 may be different from a driving voltage (e.g., VSS and / or VDD) applied to the display assembly (120) (or the display panels (332)) for duty cycle D2. For example, a difference between a first driving voltage (e.g., VSS) and a second driving voltage (e.g., VDD) applied while emitting light according to duty cycle D1 may be less than a difference between the first driving voltage and the second driving voltage applied while emitting light according to duty cycle D2. For example, at least one processor (310) may control a power management circuitry (PMIC) (not shown) of the display assembly (120) and / or the head-worn electronic device (100) such that the first driving voltage applied to emit light according to the duty cycle D1 is higher than the first driving voltage applied to emit light according to the duty cycle D2. For example, at least one processor (310) may control the PMIC of the display assembly (120) and / or the head-worn electronic device (100) such that the second driving voltage applied to emit light according to the duty cycle D1 is lower than the second driving voltage applied to emit light according to the duty cycle D2.

[0084] For example, at least one processor (310) may change, with respect to a portion of each of the display panels (332) (or a portion of a display area of ​​each of the display panels (332)), from emitting light at a peak luminance L1 according to a duty cycle D1 to emitting light at a peak luminance L2 according to a duty cycle D2. For example, at least one processor (310) may change, with respect to a portion of each of the display panels (332) (or a portion of a display area of ​​each of the display panels (332)), from emitting light at a peak luminance L2 according to a duty cycle D2 to emitting light at a peak luminance L1 according to a duty cycle D1. This operation may be performed to reduce power consumption due to the display of each of the display panels (332). This operation is described with reference to FIG. 7.

[0085] FIG. 7 illustrates an exemplary method of emitting light at a first peak brightness according to a first duty cycle through a second portion of the display panel while emitting light at a second peak brightness according to a second duty cycle through a first portion of the display panel.

[0086] Referring to FIG. 7, as in state (700), the speed of change of visual content provided on the first part (701) of each of the display panels (332) may be faster than the speed of change of visual content provided on the second part (702) of each of the display panels (332), depending on the running state of the head-worn electronic device (100). For example, the first part (701) of each of the display panels (332) may be used to display one or more contents that change more quickly with respect to the second part (702) of each of the display panels (332). For example, at least one processor (310) can control the display panels (332) to emit light with peak luminance L2 with duty cycle D2 through the first portion (701) of each of the display panels (332), and to emit light with peak luminance L1 with duty cycle D1 through the second portion (702) of each of the display panels (332), based on the first state of the head-worn electronic device (101) detected while emitting light with peak luminance L1 with duty cycle D1. For example, since the probability of motion blur occurring on the second portion (702) of each of the display panels (332) that provide content that changes at a relatively slow rate is relatively low, the at least one processor (310) can maintain emitting light with peak luminance L1 with duty cycle D1 with respect to the second portion (702) of each of the display panels (332).

[0087] As in state (750), the first part (751) of each of the display panels (332) may correspond to a foveated area recognized (or gazed upon) by the foveal vision of the user (190), and the second part (752) of each of the display panels (332) may correspond to a peripheral area recognized (or gazed upon) by the peripheral vision of the user (190). For example, the second part (752) of each of the display panels (332) may surround the first part (751) of the display panels (332). For example, at least one processor (310) can control the display panels (332) to emit light with peak luminance L2 with duty cycle D2 through the first portion (751) of each of the display panels (332), and to emit light with peak luminance L1 with duty cycle D1 through the second portion (752) of each of the display panels (332), based on the first state of the head-worn electronic device (101) detected while emitting light with peak luminance L1 with duty cycle D1. For example, since the probability that motion blur on the second portion (752) of each of the display panels (332) corresponding to the peripheral vision will be perceived by the user (190) is relatively low, the at least one processor (310) can maintain emitting light with peak luminance L1 with duty cycle D1 with respect to the second portion (752) of each of the display panels (332).

[0088] As a non-limiting example, the peak luminance L2 (and / or peak luminance L1) may be changed. For example, at least one processor (310) (or display driver circuit (331)) may collect and store data regarding the state (e.g., life state or burn-in state) of light-emitting elements (e.g., OLEDs) within the display panels (332). For example, at least one processor (310) (or display driver circuit (331)) may reduce the peak luminance L2 (and / or peak luminance L1) according to the burn-in progress state of the light-emitting elements indicated by the data. As a non-limiting example, the burn-in progress state of the OLEDs within the first display panel (121) may be different from the burn-in progress state of the OLEDs within the second display panel (122). For example, if at least some of the OLEDs in the second display panel (122) are burned-in earlier (or faster) (or more) than the OLEDs in the first display panel (122), at least one processor (310) (or display driving circuit (331)) can use the data to reduce the peak luminance L2 (and / or peak luminance L1) depending on the progress of the burn-in of at least some of the OLEDs in the second display panel (122).

[0089] Changing from emitting light with a peak luminance L2 according to a duty cycle D2 to emitting light with a peak luminance L1 according to a duty cycle D1, as described above, and / or changing from emitting light with a peak luminance L1 according to a duty cycle D1 to emitting light with a peak luminance L2 according to a duty cycle D2, can be performed at least in part using the AI ​​system illustrated in FIG. 12. For example, at least one processor (310) (and / or the display driving circuit (331)) can perform at least some of the operations described above in conjunction with the AI ​​system. For example, at least one processor (310) (and / or the display driving circuit (331)) can control the AI ​​system to perform at least some of the operations.

[0090] The sub-pixels of each of the display panels (332) for making the duty cycle of light emitted through the first portion (e.g., the first portion (701) or the first portion (751)) of each of the display panels (332) different from the duty cycle of light emitted through the second portion (e.g., the second portion (702) or the second portion (752)) of each of the display panels (332) are described with reference to FIG. 8.

[0091] FIG. 8 illustrates an example of a sub-pixel for emitting light at a first peak brightness according to a first duty cycle through a second portion of the display panel while emitting light at a second peak brightness according to a second duty cycle through a first portion of the display panel.

[0092] Referring to FIG. 8, a sub-pixel (800) may include a first transistor (811), a second transistor (812), a third transistor (813), a fourth transistor (814), a fifth transistor (815), a sixth transistor (816), a capacitor (817), a capacitor (818), and a light-emitting diode (819). The electrical connection relationship between the first transistor (811), the second transistor (812), the third transistor (813), the fourth transistor (814), the fifth transistor (815), the sixth transistor (816), the capacitor (817), the capacitor (818), and the light-emitting diode (819) within the sub-pixel (800) is merely exemplary. Various design changes may be applied to the sub-pixel (800).

[0093] The first transistor (811) may be used to generate (or obtain) a current (820) provided to the light emitting element (819) based on a data voltage (Vdata). The first transistor (811) may be configured to receive a scan signal (803) via the second transistor (812).

[0094] The second transistor (812) may be configured to receive a scan signal (803). The second transistor (812) may be configured to apply a data voltage (Vdata) to a capacitor (817) electrically connected to the gate electrode of the first transistor (811) according to the scan signal (803).

[0095] The third transistor (813) may be configured to receive a control signal (804) for controlling a duty cycle. The third transistor (813) may be configured to provide the second light-emitting signal (802) to the gate electrode of the sixth transistor (816) according to the control signal (804).

[0096] The fourth transistor (814) may be configured to receive a scan signal (803). The fourth transistor (814) may be configured to apply an initialization voltage (VINT) to a capacitor (818) electrically connected to the gate electrode of the sixth transistor (816) according to the scan signal (803).

[0097] The fifth transistor (815) may be configured to receive a first light-emitting signal (801) having a duty cycle D1. The fifth transistor (815) may be configured to provide a current (820) to the light-emitting element (819) according to the first light-emitting signal (801).

[0098] The sixth transistor (816) may be configured to receive a second light-emitting signal (802) having a duty cycle D2 lower than the duty cycle D1. The sixth transistor (816) may be configured to provide a current (820) to the light-emitting element (819) according to the second light-emitting signal (802). The sixth transistor (816) may be configured to adjust a length of time for providing the current (820) to the light-emitting element (819) according to the second light-emitting signal (802) and the control signal (804).

[0099] Control of the sub-pixels (800) to make the duty cycle of light emitted through the first part (e.g., the first part (701) or the first part (751)) of each of the display panels (332) different from the duty cycle of light emitted through the second part (e.g., the second part (702) or the second part (752)) of each of the display panels (332) is described with reference to FIG. 9.

[0100] FIG. 9 illustrates an exemplary method for driving the subpixels of FIG. 8.

[0101] Referring to FIG. 9, the display driving circuit (331) can provide a scan signal (803) to each of the second transistor (812) and the fourth transistor (814), as in state (901). For example, the data voltage (Vdata) can be applied to the capacitor (817), as in state (902), by providing the scan signal (803) to the second transistor (812).

[0102] For example, the display driving circuit (331) can provide a first light emitting signal (801) to the fifth transistor (815) as in state (903) and a second light emitting signal (802) to the sixth transistor (816) as in state (904) after applying a data voltage (Vdata) to the capacitor (817).

[0103] For example, the display driving circuit (331) can maintain, at least for a time period (913) corresponding to the duty cycle D1 of the first light emitting signal (801), the control signal (804) provided to the third transistor (813) included in the sub-pixel within the second portion within each of the display panels (332), such as in state (905), to cause the light emitting element of the sub-pixel within the second portion within each of the display panels (332) to emit light according to the duty cycle D1. For example, by maintaining the control signal (804) provided to the third transistor (813) included in the sub-pixel within the second portion within each of the display panels (332), the light emitting element included in the sub-pixel within the second portion within each of the display panels (332) can emit light according to the duty cycle D1.

[0104] For example, the display driving circuit (331) can maintain, at least for a time period (914) corresponding to the duty cycle D2 of the second light emitting signal (802), the control signal (804) provided to the third transistor (813) included in the sub-pixel within the first portion within each of the display panels (332), such as in the state (906), to cause the light emitting element of the sub-pixel within the first portion within each of the display panels (332) to emit light according to the duty cycle D2. For example, by maintaining the control signal (804) provided to the third transistor (813) included in the sub-pixel within the first portion within each of the display panels (332), the light emitting element included in the sub-pixel within the first portion within each of the display panels (332) can emit light according to the duty cycle D2.

[0105] As a non-limiting example, the display driving circuit (331) may maintain providing the control signal (804) to the third transistor (813) included in the sub-pixel within the first portion within each of the display panels (332), such as state (907), for at least a time period (915) longer than the time period (914) corresponding to the duty cycle D2 of the second light emitting signal (802), for a margin of time for the state of the sixth transistor (816) to be switched (changed) to the off state.

[0106] As a non-limiting example, the head-worn electronic device (100) may perform a display according to the PT mode described above based on emitting light according to the duty cycle D1 (or duty cycle D2). For example, within the PT mode, an external display device (e.g., a monitor or a TV) positioned in front of the head-worn electronic device (100) (e.g., in a state of displaying an image) may be displayed on the display panels (332). As a non-limiting example, when the head-worn electronic device (100) is AR glasses, the external display device may be viewed through the display panels (332) while performing a display based on emitting light according to the duty cycle D1 (or duty cycle D2) through the transparent display panels (332). For example, a moire phenomenon may occur on the display panels (332) due to a duty cycle D1 (or duty cycle D2) that does not correspond to a refresh rate of the external display device (and / or a driving frequency of one or more third sensors (343)). For example, at least one processor (310) may control each of the display panels (332) to change a duty cycle for emitting light from duty cycle D1 (or duty cycle D2) to a duty cycle corresponding to the frequency component based on identifying that a frequency component induced on the display panel (332) by the external display device does not correspond to the duty cycle D1 (or duty cycle D2). For example, according to such control, a moire phenomenon induced by the external electronic device may be reduced.

[0107] The operations within the above description may be performed by the electronic devices exemplified within the description below.

[0108] FIG. 10 is a block diagram of an electronic device (1001) within a network environment (1000) according to various embodiments. Referring to FIG. 10, in the network environment (1000), the electronic device (1001) may communicate with the electronic device (1002) via a first network (1098) (e.g., a short-range wireless communication network), or may communicate with at least one of the electronic device (1004) or the server (1008) via a second network (1099) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1001) may communicate with the electronic device (1004) via the server (1008). According to one embodiment, the electronic device (1001) may include a processor (1020), a memory (1030), an input module (1050), an audio output module (1055), a display module (1060), an audio module (1070), a sensor module (1076), an interface (1077), a connection terminal (1078), a haptic module (1079), a camera module (1080), a power management module (1088), a battery (1089), a communication module (1090), a subscriber identification module (1096), or an antenna module (1097).

For example, when the electronic device (1001) includes the main processor (1021) and the auxiliary processor (1023), the auxiliary processor (1023) may be configured to use less power than the main processor (1021) or to be specialized for a given function.

[0110] The auxiliary processor (1023) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1060), the sensor module (1076), or the communication module (1090)) of the electronic device (1001), for example, on behalf of the main processor (1021) while the main processor (1021) is in an inactive (e.g., sleep) state, or together with the main processor (1021) while the main processor (1021) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1023) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1080) or a communication module (1090)). In one embodiment, the auxiliary processor (1023) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (1001) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1008)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above.

In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0115] The display module (1060) can visually provide information to an external party (e.g., a user) of the electronic device (1001).

[0117] The sensor module (1076) can detect the operating status (e.g., power or temperature) of the electronic device (1001) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status.

The communication module (1090) may operate independently from the processor (1020) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (1090) may include a wireless communication module (1092) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (1094) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (1004) via a first network (1098) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (1099) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (1092) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (1096) to verify or authenticate the electronic device (1001) within a communication network such as the first network (1098) or the second network (1099).

[0125] The wireless communication module (1092) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimizing terminal power and connecting multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (1092) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (1092) may support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (1092) may support various requirements specified in the electronic device (1001), an external electronic device (e.g., the electronic device (1004)), or a network system (e.g., the second network (1099)).

[0126] The antenna module (1097) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (1097) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (1097) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (1098) or the second network (1099), may be selected from the plurality of antennas, for example, by the communication module (1090). A signal or power may be transmitted or received between the communication module (1090) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (1097).

[0127] According to various embodiments, the antenna module (1097) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0128] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0129] According to one embodiment, commands or data may be transmitted or received between the electronic device (1001) and an external electronic device (1004) via a server (1008) connected to a second network (1099). Each of the external electronic devices (1002 or 1004) may be the same or a different type of device as the electronic device (1001). According to one embodiment, all or part of the operations executed in the electronic device (1001) may be executed in one or more of the external electronic devices (1002, 1004, or 1008). For example, when the electronic device (1001) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (1001) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (1001).

[0130] FIG. 11 is a block diagram (1100) of a display module (1060) according to various embodiments. Referring to FIG. 11, the display module (1060) may include a display (1110) and a display driver IC (DDI) (1130) for controlling the display (1110). The DDI (1130) may include an interface module (1131), a memory (1133) (e.g., a buffer memory), an image processing module (1135), or a mapping module (1137). The DDI (1130) may receive image information including, for example, image data or an image control signal corresponding to a command for controlling the image data, from another component of the electronic device (1001) through the interface module (1131). For example, according to one embodiment, image information may be received from a processor (1020) (e.g., a main processor (1021) (e.g., an application processor) or an auxiliary processor (1023) (e.g., a graphics processing unit) that operates independently of the function of the main processor (1021). The DDI (1130) may communicate with a touch circuit (1150) or a sensor module (1076) through the interface module (1131). In addition, the DDI (1130) may store at least a part of the received image information in the memory (1133), for example, in units of frames. The image processing module (1135) may, for example, perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a part of the image data based on at least a characteristic of the image data or a characteristic of the display (1110). The mapping module (1137) may output a voltage value or a value corresponding to the image data preprocessed or postprocessed through the image processing module (1135). Current values ​​can be generated.According to one embodiment, the generation of the voltage value or current value may be performed at least in part based on, for example, properties of pixels of the display (1110) (e.g., arrangement of pixels (RGB stripe or pentile structure), or size of each sub-pixel). At least some pixels of the display (1110) may be driven at least in part based on, for example, the voltage value or current value, so that visual information (e.g., text, image, or icon) corresponding to the image data may be displayed through the display (1110).

[0131] According to one embodiment, the display module (1060) may further include a touch circuit (1150). The touch circuit (1150) may include a touch sensor (1151) and a touch sensor IC (1153) for controlling the same. The touch sensor IC (1153) may control the touch sensor (1151) to detect, for example, a touch input or a hovering input for a specific location of the display (1110). For example, the touch sensor IC (1153) may detect a touch input or a hovering input by measuring a change in a signal (e.g., voltage, light quantity, resistance, or charge quantity) for a specific location of the display (1110). The touch sensor IC (1153) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (1020). According to one embodiment, at least a portion of the touch circuit (1150) (e.g., touch sensor IC (1153)) may be included as part of the display driver IC (1130), or as part of the display (1110), or as part of another component (e.g., auxiliary processor (1023)) disposed external to the display module (1060).

[0132] According to one embodiment, the display module (1060) may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module (1076), or a control circuit therefor. In this case, the at least one sensor or the control circuit therefor may be embedded in a part of the display module (1060) (e.g., the display (1110) or the DDI (1130)) or a part of the touch circuit (1150). For example, when the sensor module (1076) embedded in the display module (1060) includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) associated with a touch input through a part of the display (1110). For another example, if the sensor module (1076) embedded in the display module (1060) includes a pressure sensor, the pressure sensor may obtain pressure information associated with a touch input through a portion or the entire area of ​​the display (1110). According to one embodiment, the touch sensor (1151) or the sensor module (1076) may be disposed between pixels of a pixel layer of the display (1110), or above or below the pixel layer.

[0133] Some of the operations described above may be executed (or performed) by an AI (artificial intelligence) system as described with reference to FIG. 12.

[0134] Figure 12 is a schematic diagram of an exemplary AI system.

[0135] Referring to FIG. 12, the AI ​​system (1200) may include an input / output interface (1210), an AI (artificial intelligence) framework (1220), a generative AI model (1230), an application / service component (1280), and / or a knowledge repository (1290).

[0136] The input / output interface (1210) can receive input. The input can include user input and / or data acquired or generated by an electronic device (e.g., the head-worn electronic device (100) or the electronic device (1001) described above). The data can include images, videos, and / or sensor data generated by at least one processor (e.g., at least one processor (310) or processor (1020)) of the electronic device (e.g., illuminance data around the electronic device acquired from a sensor or sensor hub (e.g., a coprocessor (1023), posture data (or orientation data) of the electronic device, temperature inside the electronic device (e.g., temperature of the display (120) or temperature of the at least one processor (310)), size information of a display area of ​​the display (120), and / or images acquired through an image sensor (e.g., included in a camera module (1080)) of the electronic device). The user input may include natural language, touch data obtained through touch circuitry included within the display panels (332) (e.g., used to identify input from a finger and / or a stylus), images displayed (and / or to be displayed) on the display panels (332), and / or video. As a non-limiting example, the user input may be received by the input / output interface (1210) together with context information. The context information may be described as additional information obtained in connection with the user input. The context information may relate to a state when the user input is received (e.g., including a state of the electronic device and / or a state surrounding the electronic device (e.g., a user state)). For example, the context information may include information about one or more software applications running within the electronic device when the user input is received.For example, the contextual information may include information about the location of the electronic device (or the location of the user of the electronic device) at the time the user input is received. For example, the user input may be integrated with the contextual information. For example, the user input integrated with the contextual information may be received by the input / output interface (1210).

[0137] The input / output interface (1210) can transmit (or provide) output. The output may include a result (or result information) generated or acquired by the AI ​​system (1200) based at least in part on the input. The format of the output may vary. For example, the output may include natural language. For example, the output may include content (e.g., including media content and / or multimedia content). For example, the output may include an action related to a user of the electronic device. For example, the output may have a format according to a user setting of the electronic device.

[0138] The input / output interface (1210) can be described as a user query / response interface (1210).

[0139] The AI ​​framework (1220) can be used to obtain information (or data) about the input from the input / output interface (1210) and control one or more components related to the AI ​​system (1200) using the obtained information.

[0140] For example, the prompt design component (1221) within the AI ​​framework (1220) can use the acquired information to generate or obtain a prompt for a generative AI model (1230) (e.g., including a large language model (LLM) or a large multimodal model (LMM)). For example, the prompt design component (1221) can be described as an AI component that uses a learning algorithm and / or a neural network to provide enhanced prompts over time. For example, the prompt design component (1221) can use the acquired information to access a knowledge component (e.g., a knowledge repository (1290)) that includes user preference data, a prompt library, and / or prompt examples to generate or obtain a prompt. The generated prompt can be provided to the generative AI model (1230) (e.g., including an LLM or LMM).

[0141] For example, the API / plugin management component (1222) within the AI ​​framework (1220) may be utilized to support communication for additional information requested (or induced) in connection with the prompt provided (or to be provided) to the generative AI model (1230). For example, the API / plugin management component (1222) may be utilized to create or establish channels for communication with various data sources (e.g., knowledge repositories (1290)). For example, the API / plugin management component (1222) may support access to at least some of the data sources. For example, the API / plugin management component (1222) may be utilized to request another component (e.g., an application / service component (1280)) to perform feedback (or response) according to the prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1222) may be provided to the prompt design component (1221) for generating a prompt. As a non-limiting example, information obtained (or generated) through the API / plugin management component (1222) may be provided to the generative AI model (1230).

[0142] For example, the improvement component (1223) within the AI ​​framework (1220) can at least partially tune (or adjust) (or change) the result (e.g., content) obtained (or output) from the generative AI model (1230). For example, the improvement component (1223) can determine or verify whether the content obtained from the generative AI model (1230) is related to the input. For example, the improvement component (1223) can determine or verify whether the content obtained from the generative AI model (1230) contains biased content. For example, the improvement component (1223) can determine or verify whether the content obtained from the generative AI model (1230) contains harmful content. For example, the improvement component (1223) can support or assist in performing additional processing to improve the content obtained from the generative AI model (1230). For example, the improvement component (1223) may support providing hints to the user to improve the content.

[0143] A generative AI model (1230) can be described as an artificial intelligence neural network that generates feedback in response to a prompt. For example, the feedback may include additional data and / or information related to the prompt, but relative to the prompt. For example, the feedback may include new content related to the prompt. For example, the generative AI model (1230) may include a model that generates images and / or a model that generates language. For example, the model that generates images may include a generative adversarial network (GAN) and / or a variational autoencoder (VAE). For example, the model that generates images may include a diffusion-based generative model (e.g., a transformer VAE). For example, the model that generates language may include CHAT-GPT 3 and / or CHAT-GPT 4. For example, a generative AI model (1230) may include an LMM that generates the feedback by recognizing text, images, and / or speech.

[0144] As a non-limiting example, the AI ​​framework (1220) and / or the generative AI model (1230) may be included within an AI module (e.g., including a processing circuit) within the electronic device. For example, the AI ​​module may be operatively coupled with at least one processor (e.g., at least one processor (310) or processor (1020)) of the electronic device. For example, the AI ​​module may be operatively coupled with a display driving circuit (e.g., a display driving circuit (331) or a DDI (1130)) of the electronic device. For example, the AI ​​module may be operatively coupled with a sensor hub of the electronic device for one or more sensors within the electronic device.

[0145] The technical problems to be achieved in the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary knowledge in the technical field to which the present disclosure pertains.

[0146] As described above, a head-wearable electronic device (e.g., head-wearable electronic device (100)) may include a head-wearable housing structure (e.g., head-wearable housing structure (110)), display panels (e.g., display panels (332)) each positioned over the eyes of a user wearing the head-wearable structure, one or more sensors (e.g., one or more first sensors (341)), at least one processor (e.g., at least one processor (310)) including a processing circuit, and a memory (e.g., memory (320)) storing instructions and including one or more storage media. When executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to control each of the display panels to emit light at a first peak brightness according to a first duty cycle, detect, via the one or more sensors, a movement of the head-worn electronic device outside a threshold range while emitting light at the first peak brightness according to the first duty cycle, and control, based on the detection, each of the display panels to emit light at a second peak brightness higher than the first peak brightness according to a second duty cycle lower than the first duty cycle.

[0147] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to further control each of the display panels to adjust a data voltage applied to each of the sub-pixels within each of the display panels based on the detection, independently of the image maintained on each of the display panels before and after the detection.

[0148] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to control each of the display panels to adjust the data voltage using second reference gamma data that is different from the first reference gamma data used to identify the data voltage corresponding to the image to be displayed on each of the display panels based on light emitted at the first peak luminance according to the first duty cycle prior to the detection.

[0149] For example, the brightness level of the display panels provided by emitting light with the first peak brightness according to the first duty cycle may correspond to the brightness level of the display panels provided by emitting light with the second peak brightness according to the second duty cycle.

[0150] For example, the luminous power per unit time caused by emitting light at the first peak luminance according to the first duty cycle may correspond to the luminous power per unit time caused by emitting light at the second peak luminance according to the second duty cycle.

[0151] For example, the head-worn electronic device may include a display driving circuit (e.g., display driving circuit (331)) configured to control the display panels. For example, when individually or collectively executed by the at least one processor, the instructions may cause the head-worn electronic device to control each of the display panels to emit light at the second peak brightness according to the second duty cycle by sending one or more commands to the display driving circuit to emit light at the second peak brightness according to the second duty cycle, based on the detection.

[0152] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to control each of the display panels to directly change from emitting light at the first peak luminance according to the first duty cycle to emitting light at a third peak luminance between the first peak luminance and the second peak luminance according to a third duty cycle between the first duty cycle and the second duty cycle, and to gradually change from emitting light at the third peak luminance according to the third duty cycle to emitting light at the second peak luminance according to the second duty cycle.

[0153] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to identify one of the values ​​within a first reference range as the second duty cycle based on the detection performed while the brightness level of the display panels is at a first brightness level lower than the reference brightness level, and to identify one of the values ​​within a second reference range wider than the first reference range as the second duty cycle based on the detection performed while the brightness level of the display panels is at a second brightness level higher than the reference brightness level.

[0154] For example, when the brightness level of the display panels is a first brightness level, the difference between the first duty cycle and the second duty cycle may be smaller than the difference between the first duty cycle and the second duty cycle when the brightness level of the display panels is a second brightness level higher than the first brightness level.

[0155] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to identify one of the values ​​within a first reference range as the second duty cycle based on the detection performed while the refresh rate of the display panels is a first refresh rate lower than the reference refresh rate, and to identify one of the values ​​within a second reference range wider than the first reference range as the second duty cycle based on the detection performed while the refresh rate of the display panels is a second refresh rate higher than the reference refresh rate.

[0156] For example, when the refresh rate of the display panels is a first refresh rate, the difference between the first duty cycle and the second duty cycle may be smaller than the difference between the first duty cycle and the second duty cycle when the refresh rate of the display panels is a second refresh rate higher than the first refresh rate.

[0157] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to further control each of the display panels to change a refresh rate of the display panels from a first refresh rate to a second refresh rate higher than the first refresh rate, based on the detection.

[0158] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to detect that a movement speed of visual content provided by an image displayed on each of the display panels is higher than a threshold movement speed while emitting light according to the first duty cycle at the first peak brightness, and to control each of the display panels to emit light according to a second duty cycle that is lower than the first duty cycle at a second peak brightness that is higher than the first peak brightness based on the movement speed being higher than the threshold movement speed.

[0159] For example, the head-worn electronic device may include one or more other sensors (e.g., one or more second sensors (342)) used to track the gaze of the eyes of the user wearing the head-worn structure. For example, the instructions, when executed individually or collectively by the at least one processor, may further cause the head-worn electronic device to detect, via the one or more other sensors, that a moving speed of the gaze is faster than a reference moving speed while emitting light according to the first duty cycle at the first peak brightness, and to control each of the display panels to emit light at a second peak brightness higher than the first peak brightness according to a second duty cycle lower than the first duty cycle, based on the moving speed of the gaze being faster than the reference moving speed.

[0160] For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to control each of the display panels to emit light at the second peak brightness according to the second duty cycle through the first portion of each of the display panels, based on the detection, and to emit light at the first peak brightness according to the first duty cycle through the second portion of each of the display panels.

[0161] For example, the first portion of each of the display panels may be used to display one or more contents that change more quickly than one or more contents provided on the second portion of each of the display panels.

[0162] For example, the head-mounted electronic device may include one or more other sensors (e.g., one or more second sensors (342)) used to track the gaze of the eyes of the user wearing the head-mounted structure. For example, the first portion of each of the display panels may correspond to a foveated area determined based on data acquired via the one or more other sensors. For example, the second portion of each of the display panels may correspond to a peripheral area surrounding the foveated area determined based on the data.

[0163] For example, the difference between the first driving voltage and the second driving voltage applied to the display panel while emitting light according to the second duty cycle may be greater than the difference between the first driving voltage and the second driving voltage applied to the display panel while emitting light according to the first duty cycle.

[0164] For example, the head-worn electronic device may include one or more cameras (e.g., one or more third sensors (343)) configured to acquire an image of an environment surrounding the head-worn electronic device. For example, the instructions, when executed individually or collectively by the at least one processor, may cause the head-worn electronic device to: identify, while emitting light according to the first duty cycle at the first peak brightness, that a frequency component induced on the display panel does not correspond to the first duty cycle; and, based on the identification, control each of the display panels to change a duty cycle for emitting light from the first duty cycle to a third duty cycle corresponding to the frequency component.

[0165] As described above, a head-wearable electronic device (e.g., head-wearable electronic device (100)) may include a head-wearable housing structure (e.g., head-wearable housing structure (110)), display panels (e.g., display panels (332)) each positioned over the eyes of a user wearing the head-wearable structure, one or more sensors (e.g., one or more second sensors (342)), at least one processor (e.g., at least one processor (310)) including a processing circuit, and a memory (e.g., memory (320)) storing instructions and including one or more storage media. For example, when executed individually or collectively by the at least one processor, the instructions may cause the head-worn electronic device to control each of the display panels to emit light at a first peak brightness according to a first duty cycle, detect, via the one or more other sensors, that a movement speed of the gaze is faster than a reference movement speed while emitting light at the first peak brightness according to the first duty cycle, and control, based on the detection, each of the display panels to emit light at a second peak brightness higher than the first peak brightness according to a second duty cycle lower than the first duty cycle.
