Depending on the implementation, the first plurality of light-emitting elements (352) may not be included in the first lens module (350) and the first display (360), but may be disposed on the back of the wearable electronic device (301).
[0073] According to one embodiment, at least one first lens (351) may be implemented as a lens assembly including a plurality of lenses. For example, the plurality of lenses may be arranged in a stacked manner. According to one embodiment, at least one first lens (351) may be implemented as a pancake lens structure.

According to one embodiment, the first display (360) may be implemented in a rectangular shape, and at least one first lens (351) may be implemented in a circular shape. According to one embodiment, the area of the first display (360) may be implemented to be the same as the area of at least one first lens (351). According to one embodiment, the first display (360) may be implemented in a circular shape. However, this is an example, and the area of the first display (360), the shape of the first display (360), and the shape of the at least one first lens (351) may not be limited thereto.

[0079] According to one embodiment, the processor (320) can identify multiple points formed by a plurality of invisible lights focused on one eye of the user through the first camera (330). According to one embodiment, the processor (320) can obtain an image captured by one eye of the user through the first camera (330). According to one embodiment, the processor (320) can identify a pattern of multiple points from the image. For example, the pattern of multiple points can indicate the arrangement of the multiple points.
[0080] According to one embodiment, the processor (320) may determine a first distance between at least one first lens (351) and one eye of the user based on a pattern of multiple points. According to one embodiment, the first distance may mean a lens-to-eye distance (eye relief; ER).
[0081] According to one embodiment, the first distance may mean a straight-line distance between a pupil of one eye and at least one first lens (351). According to one embodiment, when the at least one first lens (351) is implemented as a lens assembly including a plurality of lenses, the first distance may mean a straight-line distance between an outermost lens among the plurality of lenses arranged at the upper portion of the first display (360) and a pupil of one eye of the user.
[0082] According to one embodiment, the processor (320) can determine a second distance between a plurality of points. According to one embodiment, the second distance between the plurality of points may refer to a distance between two adjacent points. According to one embodiment, the processor (320) can determine the first distance based on the second distance between the plurality of points. For example, when the plurality of points exceeds two, the second distance between the plurality of points may include an average value of the distances between two adjacent points, a minimum value among the distances between two adjacent points, or a maximum value among the distances between two adjacent points.
[0083] In one embodiment, the processor (320) can determine the first distance based on the second distance between the plurality of points. For example, a lookup table indicating the relationship between the distances between the plurality of points and the distances between the lens-eye distance (ER) may be stored in the memory (340). For example, the processor (320) can determine the first distance using the lookup table indicating the relationship between the distances between the plurality of points and the distances between the lens-eye distance (ER).
[0084] According to one embodiment, the processor (320) can identify an area corresponding to a plurality of points. According to one embodiment, the area corresponding to the plurality of points may mean an area formed by the plurality of points. According to one embodiment, the processor (320) can identify a first distance based on an area of the area corresponding to the plurality of points. For example, a lookup table indicating a relationship between an area corresponding to the plurality of points and a distance between the lens-eye distance (ER) may be stored in the memory (340). For example, the processor (320) can identify the first distance using the lookup table indicating a relationship between an area corresponding to the plurality of points and a distance between the lens-eye distance (ER).
[0085] According to one embodiment, the wearable electronic device (301) may further include a depth sensor (317) (e.g., the depth sensor (317) of FIG. 4). According to one embodiment, the processor (320) may use the depth sensor (317) included in the wearable electronic device (301) to determine a first distance between at least one first lens (351) and one eye of the user. According to one embodiment, the processor (320) may transmit a signal to one eye of the user through the depth sensor (317) and determine the first distance using a signal reflected from one eye of the user. According to one embodiment, the depth sensor (317) may be implemented in the same or similar manner as the depth sensor (217) of FIG. 2A.
[0086] According to one embodiment, the wearable electronic device (301) may include a dial (311) (e.g., the dial (311) of FIG. 4) that can adjust a distance between at least one first lens (351) and one eye of the user. According to one embodiment, when the dial (311) is rotated, a portion (540) of a housing of the wearable electronic device (301) (e.g., a portion (540) of the housing of FIG. 5B) may move. According to one embodiment, as the portion (540) of the housing moves, the portion (540) of the housing may come into contact with a portion of the user's face (e.g., the forehead). According to one embodiment, as the dial is rotated, the portion (540) of the housing may move. According to one embodiment, as the portion (540) of the housing moves, the distance between the at least one first lens (351) and one eye of the user may be adjusted. According to one embodiment, the processor (320) can determine a first distance between at least one first lens (351) and one eye of the user based on the number of rotations of the dial. For example, a lookup table indicating a relationship between the number of rotations of the dial and the distance between the lens-to-eye distance (ER) can be stored in the memory (340). For example, the processor (320) can determine the first distance using the lookup table indicating a relationship between the number of rotations of the dial and the distance between the lens-to-eye distance (ER).
[0087] However, this is an example, and embodiments of the present document can determine the distance between at least one first lens (351) and one eye of the user in various ways.
[0088] According to one embodiment, a first plurality of pixels included in a first display (360) may output light. According to one embodiment, light output from the first plurality of pixels included in the first display (360) may transmit at least one first lens (351). According to one embodiment, the luminance of the light transmitted through the at least one first lens (351) may be less than the luminance of the light output from the first plurality of pixels. According to one embodiment, the luminance of the light transmitted through the at least one first lens (351) may decrease as it moves away from a position corresponding to a third distance with respect to the center of the at least one first lens (351) toward the end of the at least one first lens (351). For example, the third distance may mean a point at which the luminance of the light transmitted through the at least one first lens (351) begins to decrease with respect to the center of the at least one first lens (351). For example, the third distance may mean a distance corresponding to 0.5 times the radius of at least one first lens (351). However, this is an example, and the third distance may not be limited thereto.
[0089] According to one embodiment, the processor (320) may adjust the brightness of light output from at least one pixel among the first plurality of pixels so that the brightness of light transmitted through at least one first lens (351) decreases as it moves away from a position corresponding to a first designated distance that is further than the third distance from the center of at least one first lens (351) toward the end of at least one first lens (351). At this time, according to one embodiment, the processor (320) may adjust the brightness of light output from at least one pixel among the first plurality of pixels so that a rate at which the brightness of light transmitted through at least one first lens (351) decreases becomes relatively small. For example, the processor (320) may adjust the brightness of light output from at least one pixel by adjusting the intensity of light output from the at least one pixel. For example, the first designated distance may mean a distance corresponding to 0.8 times the radius of at least one first lens (351). However, this is an example, and the first specified distance may not be limited thereto. For example, at least one pixel may mean at least one unit pixel.
[0090] According to one embodiment, the processor (320) may adjust the brightness of light output from at least one pixel among the first plurality of pixels so that the brightness of light transmitted through at least one first lens (351) has a constant value over the entire area of at least one first lens (351) regardless of the distance from the center of the at least one first lens (351).
[0091] According to one embodiment, the processor (320) may adjust the brightness of light output from at least one pixel among the first plurality of pixels based on the first distance. According to one embodiment, the processor (320) may adjust the brightness of light output from at least one pixel among the first plurality of pixels using a lookup table representing a relationship between the first distance, the brightness of light output from the first plurality of pixels, and a plurality of fields (fields; F) of at least one first lens (351). According to one embodiment, the lookup table may include an adjusted brightness value of light output from at least one pixel among the first plurality of pixels. According to one embodiment, the lookup table may be stored in the memory (340) or in a memory included in a display driver IC (not shown).
[0092] According to one embodiment, the lookup table can be obtained based on a first distance, a luminance map based on luminance values of light output from the first display (360), and a luminance map based on luminance values confirmed after passing through at least one first lens (351).
[0093] According to one embodiment, the processor (320) may obtain a luminance value of light output from the first display (360). At this time, the processor (320) may obtain a luminance value output from each of the first plurality of pixels included in the first display (360) and obtain a first luminance map based on the luminance value. According to one embodiment, the processor (320) may obtain a luminance value confirmed after passing through at least one first lens (351) when the distance between at least one first lens (351) and one eye of the user is a first distance. According to one embodiment, the processor (320) may obtain a second luminance map based on a luminance value confirmed after passing through at least one first lens (351). According to one embodiment, the processor (320) may determine an adjustment value of the luminance of light output from at least one pixel among the first plurality of pixels to obtain a third luminance map using the first luminance map and the second luminance map. For example, the third luminance map may mean a luminance map in which the luminance distribution of light transmitted through at least one first lens (351) is uniform in the entire area of the at least one first lens (351). According to one embodiment, the processor (320) may obtain a lookup table using the first distance, the first luminance map, the second luminance map, and the third luminance map.
[0094] In one embodiment, the plurality of fields may be defined based on a distance from the center of at least one first lens (351). In one embodiment, the center of at least one first lens (351) may coincide with the center of the first display (360). Each of the plurality of fields may refer to a set of positions that are the same distance from the center of at least one first lens (351). The plurality of fields may be defined as a value between 0 and 1. For example, 0F may refer to the center of at least one first lens (351). For example, 0.5F may refer to a set of positions that correspond to a distance of 0.5 times the radius of at least one first lens (351) from the center of at least one first lens (351). For example, 0.8F may refer to a set of positions that correspond to a distance of 0.8 times the radius of at least one first lens (351) from the center of at least one first lens (351). For example, 1F may mean a set of positions corresponding to a distance of the radius of at least one first lens (351) from the center of at least one first lens (351).
[0095] However, this is an example, and the center of at least one first lens (351) and the center of the first display (360) may not coincide. Even in this case, the plurality of fields may be defined in the same way as when the center of at least one first lens (351) and the center of the first display (360) coincide based on the distance from the center of at least one first lens (351).
[0096] According to one embodiment, the processor (320) can adjust the brightness of light by adjusting the intensity of light output from the first plurality of pixels. According to one embodiment, the processor (320) can adjust the intensity of light output from at least one pixel among the first plurality of pixels based on the positions of the first plurality of pixels corresponding to the plurality of fields of at least one first lens (351).
[0097] According to one embodiment, the processor (320) may adjust the intensity of a first light output from at least one first pixel corresponding to a first specified distance from the center of the first display (360) among the first plurality of pixels to be greater than the intensity of a second light output from at least one second pixel corresponding to a second specified distance that is closer than the first specified distance from the center of the first display (360). For example, the at least one first pixel corresponding to the first specified distance may refer to a pixel positioned at a position corresponding to 0.8F of at least one first lens (351). For example, the at least one second pixel corresponding to the second specified distance may refer to a pixel positioned at a position corresponding to 0.5F of at least one first lens (351).
[0098] Table 1 below is a table showing an example of a lookup table representing a relationship between a first distance, an adjusted brightness of light output from each of a first plurality of pixels, and a plurality of fields (fields; F) of at least one first lens (351). However, the lookup table may not be limited to the numerical values described in Table 1 below. For example, before the processor (320) performs an operation of adjusting the brightness of light output from the first display (360), the processor (320) may output light of about 1250 nits through the first display (360), regardless of the field of the first display (360).
[0099] When Field(F)ER is 12mm, luminance(nit) When ER is 16mm, luminance(nit) When ER is 20mm, luminance(nit)01250125012500.11250125012500.21250125012500.31250125012500.41250125012600.51250125012700.61260128013000.71270132013800.81290145016600.91290145016601129014501660
[0100] For example, when the first distance is 12 mm, the processor (320) may not adjust the luminance of the light output from the first display (360) between 0F and about 0.5F. The processor (320) may increase the luminance value of the light output from the first display (360) between about 0.5F and 1F. The processor (320) may adjust the intensity of the light output from at least one pixel among a plurality of pixels arranged at a corresponding position between about 0.8F and 1F so that the adjusted luminance value of the light is the same between 0.8F and 1F. For example, when the first distance is 16 mm, the processor (320) may not adjust the luminance of the light output from the first display (360) between 0F and about 0.5F. The processor (320) may increase the luminance value of the light output from the first display (360) between about 0.5F and 1F. The processor (320) may adjust the intensity of light output from at least one pixel among the plurality of pixels arranged at positions corresponding to between about 0.8F and 1F so that the luminance value of light adjusted between about 0.8F and 1F is the same. For example, when the first distance is 20 mm, the processor (320) may not adjust the luminance of light output from the first display (360) between about 0F and about 0.3F. The processor (320) may increase the value of the luminance of light output from the first display (360) between about 0.3F and 1F. The processor (320) may adjust the intensity of light output from at least one pixel among the plurality of pixels arranged at positions corresponding to between about 0.8F and 1F so that the luminance value of light adjusted between about 0.8F and 1F is the same.
[0101] Through this, after the brightness of the light output from the first display (360) is adjusted, the brightness of the light transmitted through the first lens (351) may decrease from a field farther from the center of at least one first lens (351) relatively than the brightness of the light transmitted through the first lens (351) before the brightness of the light output from the first display (360) is adjusted. The rate at which the brightness of the light transmitted through the first lens (351) decreases after the brightness of the light output from the first display (360) is adjusted may be relatively less than the rate at which the brightness of the light transmitted through the first lens (351) decreases before the brightness of the light output from the first display (360) is adjusted. According to one embodiment, the processor (320) may adjust the brightness value of the light output from a plurality of pixels arranged at positions corresponding to between 0.8F and 1F to have a specific value and no longer increase, thereby reducing the current consumed for adjusting the brightness of the light. The processor (320) can provide a clear screen including a virtual object displayed through the first lens (351) by adjusting the luminance distribution of light output from the first display (360) to be uniform in a plurality of fields.
[0102] According to one embodiment, the processor (320) may include a main processor (e.g., the main processor (121) of FIG. 1) and an auxiliary processor (e.g., the auxiliary processor (123) of FIG. 1). According to one embodiment, the operation of checking the distance between at least one first lens (351) and one eye of the user may be performed by the auxiliary processor. According to one embodiment, the operation of adjusting the brightness of light output from the first display (360) may be performed by the main processor. However, this is an example, and the operations performed by the embodiments of the present disclosure may be performed by the main processor or the auxiliary processor.
[0103] According to one embodiment, the processor (320) may use a lookup table stored in the memory (340) to identify an adjustment value of the luminance of light output from at least one pixel among the first plurality of pixels and a field corresponding to the at least one pixel. According to one embodiment, the processor (320) may transmit the adjustment value and the field to a display driver IC (DDI). According to one embodiment, the display driver IC may adjust the intensity of light output from at least one pixel located in the field based on the adjustment value and the field.
[0104] The operations of the wearable electronic device (301) described in the drawings below may be performed by the processor (320). However, for convenience of explanation, the operations performed by the processor (320) will be described as being performed by the wearable electronic device (301).

[0109] According to one embodiment, when the dial (311) is rotated, the distance between at least one first lens (351) and one eye of the user and the distance between at least one second lens (371) and the other eye of the user can be adjusted.

[0123] According to one embodiment, in operation 615, the wearable electronic device (301) can determine a first distance between the first lens (351) and the eye based on a pattern of multiple dots. For example, the pattern of multiple dots may indicate an arrangement state of the multiple dots.
[0124] According to one embodiment, the wearable electronic device (301) can check a second distance between a plurality of points, and check a first distance based on the second distance. According to one embodiment, the second distance between the plurality of points may refer to a distance between two adjacent points. For example, when the plurality of points exceeds two, the second distance between the plurality of points may include an average value of the distances between two adjacent points, a minimum value among the distances between two adjacent points, or a maximum value among the distances between two adjacent points. According to one embodiment, the wearable electronic device (301) can check the first distance using a lookup table representing a relationship between the distances between the plurality of points and the distances between the lens-eye distance (ER).
[0125] According to one embodiment, the wearable electronic device (301) may determine the area of a region corresponding to a plurality of points and determine a first distance based on the area. According to one embodiment, the wearable electronic device (301) may determine the first distance using a lookup table representing the relationship between the area corresponding to a plurality of points and the distance between the lens and the eye distance (ER).
[0126] According to one embodiment, in operation 617, the wearable electronic device (301) may adjust the luminance distribution of light output from the first display (360) based on the first distance. According to one embodiment, the wearable electronic device (301) may adjust the luminance distribution of light output from the first display (360) by adjusting the luminance of light output from at least one pixel among the first plurality of pixels included in the first display (360). According to one embodiment, the wearable electronic device (301) may adjust the luminance distribution of light output from the first display (360) by using a lookup table representing the relationship between the first distance, the luminance of light output from at least one pixel among the first plurality of pixels, and the plurality of fields (fields; F) of at least one first lens (351).
[0127] According to one embodiment, the plurality of fields may be defined based on a distance from a center of at least one first lens (351). Each of the plurality of fields may refer to a set of positions having the same distance from a center of at least one first lens (351). According to one embodiment, the lookup table may include a luminance value of adjusted light output from at least one pixel among the first plurality of pixels. According to one embodiment, the lookup table may be stored in the memory (340) or in a memory included in a display driver IC (not shown).
[0128] According to one embodiment, the wearable electronic device (301) can adjust the brightness of light by adjusting the intensity of light output from at least one pixel among the first plurality of pixels included in the first display (360). For example, the wearable electronic device (301) can adjust the intensity of light output from at least one pixel based on the position of at least one pixel among the first plurality of pixels corresponding to at least one field among the plurality of fields of at least one first lens (351).
[0129] According to one embodiment, the wearable electronic device (301) may adjust the intensity of light output from at least one first pixel corresponding to a first specified distance from the center of the first display (360) among the first plurality of pixels to be greater than the intensity of light output from at least one second pixel corresponding to a second specified distance (e.g., a distance of 0.5 times the radius) that is closer than the first specified distance (e.g., a distance of 0.8 times the radius) from the center of the first display (360). For example, the at least one first pixel corresponding to the first specified distance may mean a pixel positioned at a position corresponding to 0.8F of the at least one first lens (351), and 0.8F may mean a set of positions corresponding to a distance of 0.8 times the radius of the first lens (351) from the center of the at least one first lens (351). For example, at least one second pixel corresponding to the second specified distance may mean a pixel positioned at a position corresponding to 0.5F of at least one first lens (351), and 0.5F may mean a set of positions corresponding to a distance of 0.5 times the radius of the first lens (351) from the center of at least one first lens (351).
[0130] According to one embodiment, when the luminance of light output from at least one pixel among the first plurality of pixels is adjusted, the luminance of light transmitted through at least one first lens (351) may decrease as it moves away from a position corresponding to a first specified distance toward the end of the at least one first lens (351). The position corresponding to the first specified distance may be a distance further than a position corresponding to a third distance at which the luminance of light transmitted through the at least one first lens (351) decreases before the luminance of the light is adjusted. For example, the first specified distance may mean a distance corresponding to 0.8 times the radius of the at least one first lens (351). For example, the third distance may mean a point at which the luminance of light transmitted through the at least one first lens (351) begins to decrease with respect to the center of the at least one first lens (351). For example, the third distance may mean a distance corresponding to 0.5 times the radius of the at least one first lens (351). However, this is an example, and the first designated distance and the third distance may not be limited thereto.
[0131] According to one embodiment, when the luminance distribution of light output from the first display (360) is adjusted, the rate at which the luminance of light transmitted through at least one first lens (351) decreases may be smaller than the rate at which the luminance of light transmitted through at least one first lens (351) decreases before the luminance distribution of light output from the first display (360) is adjusted.
[0132] According to one embodiment, the wearable electronic device (301) can provide a clear screen including a virtual object displayed through at least one first lens (351) by adjusting the luminance distribution of light output from the first display (360) to be uniform in a plurality of fields.

[0140] FIG. 8 is a drawing for explaining at least one first lens and a first display according to one embodiment.
[0141] Referring to FIG. 8, according to one embodiment, a first display (360) (e.g., the first display (360) of FIG. 3) may be disposed at a lower portion of at least one first lens (351) (e.g., at least one first lens (351) of FIG. 3).

[0144] According to one embodiment, the area of the first display (360) may be implemented larger than the area of at least one first lens (351). According to one embodiment, the first display (360) may be implemented in a rectangular shape, and at least one first lens (351) may be implemented in a circular shape. According to one embodiment, the center of the first display (360) may coincide with the center (801) of at least one first lens (351). However, this is an example, and the area of the first display (360), the shape of the first display (360), and the shape of the first lens (351) may not be limited thereto. However, this is an example, and the center of the first display (360) may not coincide with the center (801) of at least one first lens (351).
[0145] According to one embodiment, the wearable electronic device (301) may adjust the brightness of light output from the first display (360) based on a first distance (e.g., ER distance). According to one embodiment, the wearable electronic device (301) may adjust the brightness of light output from at least one pixel among the first plurality of pixels by using a lookup table representing the relationship between the first distance, the brightness of light output from each of the first plurality of pixels, and the plurality of fields (fields; F) of the first display (360). For example, the wearable electronic device (301) may adjust the intensity of light output from at least one pixel located in any one of the plurality of fields.
[0146] According to one embodiment, the wearable electronic device (301) can adjust the brightness of light by adjusting the intensity of light output from at least one pixel among the first plurality of pixels. According to one embodiment, the wearable electronic device (301) can adjust the intensity of light output from at least one pixel based on the position of the at least one pixel among the first plurality of pixels.
[0147] According to one embodiment, the wearable electronic device (301) can adjust the intensity of light output from at least one pixel located in each of a plurality of fields (fields; F) of at least one first lens (351). According to one embodiment, the plurality of fields can be defined based on a distance from a center (801) of at least one first lens (351).
[0148] According to one embodiment, each of the plurality of fields may refer to a set of positions that are the same distance from the center (801) of at least one first lens (351). For example, 0.5F (810) may refer to a position corresponding to a distance of 0.5 times the radius of at least one first lens (351) from the center (801) of at least one first lens (351). For example, 0.8F (820) may refer to a position corresponding to a distance of 0.8 times the radius of at least one first lens (351) from the center (801) of at least one first lens (351). For example, 1F (830) may refer to a position corresponding to a distance of the radius of at least one first lens (351) from the center (801) of at least one first lens (351).
[0149] According to one embodiment, the wearable electronic device (301) may adjust the intensity of light output from at least one first pixel (821, 822) located at a first specified distance from the center of at least one first lens (351) among the first plurality of pixels to be greater than the intensity of light output from at least one second pixel (811, 812) located at a second specified distance closer than the first specified distance from the center of at least one first lens (351). For example, the at least one first pixel corresponding to the first specified distance may refer to a pixel positioned at a position corresponding to 0.8F (820) of the at least one first lens (351). For example, the at least one second pixel (811, 812) corresponding to the second specified distance may refer to a pixel positioned at a position corresponding to 0.5F (810) of the at least one first lens (351).

For example, at least one third pixel (831, 832) corresponding to the third specified distance may mean a pixel positioned at a position corresponding to 1F (830) of at least one first lens (351). However, the third specified distance may not be limited to the above example.
[0150] According to one embodiment, the wearable electronic device (301) may adjust pixels positioned at positions corresponding to between 0.8F (820) and 1F (830) of at least one first lens (351) to output light with the same light intensity. According to one embodiment, the wearable electronic device (301) may not adjust the luminance of light of a plurality of pixels corresponding to positions at a distance less than a second specified distance from the center of at least one first lens (351) among the first plurality of pixels. According to one embodiment, the wearable electronic device (301) may adjust the luminance of light of a plurality of pixels corresponding to positions at a distance greater than the second specified distance from the center of at least one first lens (351).

For example, the wearable electronic device (301) can adjust the light intensity of pixels positioned at a relatively far distance from the center of at least one first lens (351) among the plurality of pixels positioned between the second specified distance and the first specified distance to be relatively greater. Through this, the wearable electronic device (301) can have a luminance of light output from at least one first lens (351) that is constant between the center of at least one first lens (351) and the first specified distance.
[0152] According to one embodiment, the wearable electronic device (301) can adjust the luminance of light of a plurality of pixels located between a first designated distance and a third designated distance from a center of at least one first lens (351) to have the same value. Through this, the wearable electronic device (301) can have a reduction ratio of the luminance of light output from at least one first lens (351) between the first designated distance and the third designated distance from the center of at least one first lens (351) be relatively smaller than a ratio of the luminance of light output from at least one first lens (351) before adjustment.
[0153] According to one embodiment, the wearable electronic device (301) may adjust the brightness of light output from each of the first plurality of pixels so that the brightness of light transmitted through at least one first lens (351) is constant between the center (801) of the at least one first lens (351) and a position corresponding to a first designated distance from the center, and may decrease as the distance increases from the position corresponding to the first designated distance to a position corresponding to a third designated distance.

[0163] Referring to (a) of FIG. 10, the y-axis of the graph may mean the luminance value of light output from the first display (360) (e.g., the first display (360) of FIG. 3), and the x-axis of the graph may mean a field (F).
[0164] According to one embodiment, when the ER is 12 mm, the luminance (1030) of light output from the first display (360) may be constant at about 1250 nit between 0F and about 0.5F, and may increase between about 0.6F and 1F.
[0165] According to one embodiment, when ER is 16 mm, the luminance (1020) of light output from the first display (360) is constant at about 1250 nit between OF and about 0.5F, and may increase between about 0.5F and 1F.
[0166] According to one embodiment, when ER is 20 mm, the luminance (1030) of light output from the first display (360) is constant at about 1250 nit between OF and about 0.4F, and may increase between about 0.4F and 1F.

The luminance distribution of light transmitted through at least one first lens (351) may be uniform across multiple fields. Through this, the wearable electronic device (301) may provide a relatively improved visual experience to a user wearing the wearable electronic device (301) through the at least one first lens (351).
[0169] FIG. 11 is a diagram illustrating a graph related to the adjusted brightness of light output from a first display and the brightness of light transmitted through a first lens according to one embodiment.

[0171] In one embodiment, when the ER is 12 mm, the luminance (1130) of the light output from the first display (360) may be constant at about 1250 nit between OF and about 0.5F, and may increase between about 0.5F and about 0.8F.

In one embodiment, the luminance (1120) of the light output from the first display (360) may be constant between about 0.8F and 1F.
[0173] In one embodiment, when the ER is 20 mm, the luminance (1110) of the light output from the first display (360) may be constant at about 1250 nit between OF and about 0.3F, and may increase between about 0.3F and about 0.8F. In one embodiment, the luminance (1110) of the light output from the first display (360) may be constant between about 0.8F and 1F.
[0174] According to one embodiment, the wearable electronic device (301) (e.g., the wearable electronic device (301) of FIG. 3) can adjust the luminance of light so that the value of the luminance of light output from the first display (360) becomes relatively larger as the ER is farther away. For example, the luminance (1130) of light confirmed between about 0.8F and 1F may be 1290 nit. For example, the luminance (1120) of light confirmed between about 0.8F and 1F may be 1450 nit. For example, the luminance (1110) of light confirmed between about 0.8F and 1F may be 1660 nit.
[0175] Referring to (b) of FIG. 11, the y-axis of the graph may mean the luminance value of light transmitted through at least one first lens (351) (e.g., at least one first lens (351) of FIG. 3), and the x-axis of the graph may mean a field (F).
[0176] In one embodiment, when the ER is 12 mm, the luminance (1140) of light transmitted through at least one first lens (351) may be constant at about 100 nit between OF and about 0.8F, and may decrease between about 0.8F and 1F. In one embodiment, the luminance (1140) of light transmitted through at least one first lens (351) may decrease from about 100 nit to about 60 nit.
[0177] In one embodiment, when the ER is 16 mm, the luminance (1150) of light transmitted through at least one first lens (351) may be constant at about 100 nit between OF and about 0.8F, and may decrease between about 0.8F and 1F. In one embodiment, the luminance (1150) of light transmitted through at least one first lens (351) may decrease from about 100 nit to about 60 nit.
[0178] In one embodiment, when the ER is 20 mm, the luminance (1160) of light transmitted through at least one first lens (351) may be constant at about 100 nit between OF and about 0.8F, and may decrease between about 0.8F and 1F. In one embodiment, the luminance (1160) of light transmitted through at least one first lens (351) may decrease from about 100 nit to about 60 nit.
[0179] According to one embodiment, in 1F, the luminance (1140, 1150, 1160) of light transmitted through at least one first lens (351) may be the same regardless of the ER value.
[0180] In one embodiment, the rate at which the luminance of light (1140) identified between about 0.8F and about 0.9F decreases may be relatively smaller than the rate at which the luminance of light (1150) identified between about 0.8F and about 0.9F decreases and the rate at which the luminance of light (1160) identified between about 0.8F and about 0.9F decreases. In one embodiment, the rate at which the luminance of light (1150) identified between about 0.8F and about 0.9F decreases may be relatively smaller than the rate at which the luminance of light (1160) identified between about 0.8F and about 0.9F decreases.
[0181] In one embodiment, the rate at which the luminance of light (1160) observed between about 0.9F and 1F decreases may be relatively smaller than the rate at which the luminance of light (1150) observed between about 0.9F and 1F decreases and the rate at which the luminance of light (1140) observed between about 0.9F and 1F decreases. In one embodiment, the rate at which the luminance of light (1150) observed between about 0.9F and 1F decreases may be relatively smaller than the rate at which the luminance of light (1140) observed between about 0.9F and 1F decreases.
[0182] According to one embodiment, a rate at which the luminance (1140) of light transmitted through at least one first lens (351) is reduced may be relatively smaller than a rate at which the luminance (920) of light transmitted through at least one first lens (351) (e.g., luminance (920) of FIG. 9) is reduced. A distribution of the luminance (1140) of light transmitted through at least one first lens (351) may be relatively more uniform than a distribution of the luminance (920) of light transmitted through at least one first lens (351).
[0183] According to one embodiment, since the luminance (1130) of light output from the first display (360) is constant between about 0.8F and 1F, the current consumed to output the luminance (1130) of light may be relatively smaller than the current consumed to output the luminance (1030) of light (e.g., the luminance (1030) of FIG. 10).
[0184] According to one embodiment, a wearable electronic device (301) may include a camera (330, 331), a display (360, 380) including a plurality of pixels, a lens module (350, 370) including at least one lens (351, 371) and a plurality of light-emitting elements (352, 372), a processor (320), and a memory (340) storing instructions.
