[0066] FIG. 2 is a block diagram of an example configuration of an electronic device according to various embodiments. FIG. 2 will be described with reference to FIGS. 3A, 3B, 3C, and 4. FIG. 3A is a diagram for explaining an example of changing the brightness level of a display according to various embodiments.

FIG. 3C is a diagram for explaining an example of power consumed according to the brightness of a screen provided through a display according to various embodiments. FIG. 4 is a diagram for explaining at least one sensor arranged in an electronic device according to various embodiments.

[0067] In one embodiment, the electronic device (101) may be the electronic device (101) of FIG. 1.

[0068] Referring to FIG. 2, in one embodiment, the electronic device (101) may include a display (210), at least one sensor (220), a camera (230), a memory (240), and / or a processor (e.g., including a processing circuit) (250).

[0069] In one embodiment, the display (210) may be included in the display module (160) of FIG. 1. A screen having a brightness level set by the processor (250) may be provided through the display (210). For example, in an environment where direct sunlight is incident on the electronic device (101) outdoors, the brightness level of the display (210) may be set to a set maximum brightness level (e.g., 1300 nit). Referring to FIG. 3A, the brightness level of the display (210) may be set to a high brightness level (e.g., 1300 nit) or a low brightness level (e.g., 400 nit). The brightness level of the display (210) may include various brightness levels in addition to the example of FIG. 3A, and an example in which the brightness level of the display (210) is controlled to an intermediate brightness level between 1300 nit and 400 nit will be described in more detail below. "nit" may represent, for example, a luminance of 1 cd per square meter. In one embodiment, when a screen (310) having a luminance level of 1300 nits is continuously displayed through the display (10), the consumed current may increase. When a screen (320) having a luminance level of 400 nits is displayed through the display (210), relatively less current may be consumed compared to when the luminance level of the display is set to 1300 nits. Referring to FIG. 3B, in one embodiment, the luminance of the display (210) (or panel) may be determined by the design of the panel and / or the supplied power. The display (210) may include an AMOLED (active-matrix organic light emitting diode) circuit. The luminance of the panel may be determined, for example, by the difference between the potential of the ELVDD(+) signal and the potential of the ELVDD(-) signal. The ELVDD(+) signal can be provided to the display (210) based on a value set corresponding to the type of panel.The potential of the ELVDD(+) signal may not depend on the luminance of the display (210) while the display (210) is driven. For example, the magnitude (311) of the voltage corresponding to the ELVDD(+) signal for a luminance level of 1300 nits may be the same as the magnitude (321) of the voltage corresponding to the ELVDD(+) signal for a luminance level of 400 nits. The potential of the ELVDD(-) signal may have a negative value. As the potential of the ELVDD(-) signal decreases, the luminance of the display (210) may increase. For example, the potential of the ELVDD(-) signal for a luminance level of 1300 nits may be lower than the potential of the ELVDD(-) signal for a luminance level of 400 nits. The magnitude (313) (or absolute value) of the voltage of the ELVDD(-) signal for a luminance level of 1300 nits may be greater than the magnitude (323) (or absolute value) of the voltage of the ELVDD(-) signal for a luminance level of 400 nits. The difference between the potential of the ELVDD(+) signal and the potential of the ELVDD(-) signal for a luminance level of 1300 nits may be greater than the difference between the potential of the ELVDD(+) signal and the potential of the ELVDD(-) signal for a luminance level of 400 nits. The sum of the magnitude of the voltage corresponding to the ELVDD(+) signal (311) and the magnitude of the voltage corresponding to the ELVDD(-) signal (313) for a luminance level of 1300 nit may be greater than the sum of the magnitude of the voltage corresponding to the ELVDD(+) signal (321) and the magnitude of the voltage corresponding to the ELVDD(-) signal (323) for a luminance level of 400 nit.

[0070] In one embodiment, the display (210) may be an AMOLED display. Referring to FIG. 3C, in one embodiment, the display (210) may require a very large amount of power to be driven under an OPR (on pixel ratio) condition of 100% (or full white). If the display (210) is driven for a long period of time at a set maximum brightness level (e.g., 1300 nits) under outdoor direct sunlight conditions, the display (210) may generate heat. The surface temperature of the electronic device (101) may continuously rise due to the heat generation of the display (210). The electronic device (101) may perform heat control based on determining that the surface temperature reaches a set threshold. For example, the electronic device (101) may control the brightness level of the display (210) to be below a set minimum value.

[0071] In one embodiment, the display (210) may be a foldable display comprising a plurality of regions separated by at least one folding line.

[0072] In one embodiment, at least one sensor (220) may be included in the sensor module (176) of FIG. 1.

[0073] In one embodiment, at least one sensor (220) may include at least one thermistor. The at least one thermistor may be disposed within the electronic device (101). The at least one thermistor may be configured to output information associated with the temperature of the electronic device (101). Referring to FIG. 4, a plurality of thermistors (411, 412, 413, 414, 415, 416, 417, 418, 419) may be disposed within the electronic device (101) (or the housing) to monitor the temperature of the electronic device (101). The electronic device (101) can check the temperature of at least one component disposed within the electronic device (101) by using each of the plurality of thermistors (411, 412, 413, 414, 415, 416, 417, 418, 419) for stable operation. Each of the plurality of thermistors (411, 412, 413, 414, 415, 416, 417, 418, 419) can be implemented as at least a part of each of the plurality of components disposed within the electronic device (101). Each of the plurality of thermistors (411, 412, 413, 414, 415, 416, 417, 418, 419) can also be disposed at a position adjacent to each of the plurality of components disposed within the electronic device (101). The electronic device (101) can control an operation corresponding to at least one component based on the temperature of the at least one component that has been identified. In one embodiment, the electronic device (101) can identify the temperature of the electronic device (101) using a plurality of thermistors (411, 412, 413, 414, 415, 416, 417, 418, 419). The electronic device (101) can also identify (or estimate) the current surface temperature of the electronic device (101) based on values ​​obtained from at least some of the plurality of thermistors (411, 412, 413, 414, 415, 416, 417, 418, 419).For example, the electronic device (101) can calculate the surface heating temperature based on matching (or combining) the temperature of the thermistor measured in advance for each use case with the current heating measurement result.

[0074] In one embodiment, at least one sensor (220) may include a light sensor. At least one sensor (220) may also include a grip sensor.

[0075] In one embodiment, the camera (230) may be included in the camera module (180) of FIG. 1. In one embodiment, the camera (230) may acquire images of objects outside the electronic device (101). The camera (230) may include, for example, a front camera.

[0076] In one embodiment, memory (240) may be included in memory (130) of FIG. 1. Memory (240) may store instructions. The instructions, when individually or collectively executed by processor (250), may cause the electronic device (101) to perform operations.

[0077] In one embodiment, the processor (250) may be included in the processor (120) of FIG. 1, and the description of the processor (120) as described above applies equally to the processor (250).

[0078] In one embodiment, the processor (250) may include various processing circuits and may control the overall operation for controlling the brightness level of the display (210). The processor (250) may include one or more processors for performing the operation for controlling the brightness level of the display (210). For example, the processor (250) may correspond to multiple processors that collectively perform multiple operations by dividing them among the processors. The processor (250) may include processing circuits (not shown). The operations performed by the processor (250) will be described below.

[0079] In one embodiment, the processor (250) may include a neural processing unit (NPU) for controlling the brightness level of the display (210). For example, the processor (250) may include a graphic processing unit (GPU) capable of performing the brightness control operation of the display (210) using a specified algorithm when the brightness control operation of the display (210) is performed using a specified algorithm.

[0080] FIG. 5 is a flowchart illustrating an example method for controlling a brightness level of a display of an electronic device according to various embodiments. FIG. 5 will be described with reference to FIGS. 6A, 6B, 6C, 7A, 7B, and 8. FIG. 6A is a diagram illustrating an example method for changing a brightness level of a display of an electronic device according to various embodiments. FIG. 6B is a diagram illustrating an example current consumed according to a brightness level of a display according to various embodiments. FIG. 6C is a graph illustrating a time period during which an electronic device can operate at high brightness according to a brightness level of a display according to various embodiments. FIG. 7A is a graph illustrating an example of a temperature change rate of an electronic device according to various embodiments. FIG. 7B is a graph illustrating an example of reducing a brightness level of a display of an electronic device according to various embodiments. FIG. 8 is a graph illustrating an example operation of reducing the brightness level of a display of an electronic device to an intermediate brightness level according to various embodiments.

[0081] Referring to FIG. 5, in operation 501, in one embodiment, when a brightness level of a display (e.g., a display 210 of FIG. 2) is set to a first level based on an ambient light level, the electronic device (101) (e.g., the processor 250 of FIG. 2) may determine, when a temperature of the electronic device (101) identified using at least one sensor (e.g., at least one sensor 220 of FIG. 2) reaches a first temperature, a temperature change rate within a specified time interval may be identified, and based on the identified temperature change rate, an intermediate temperature may be determined for reducing the brightness level of the display to an intermediate brightness level between the first level and a second level lower than the first level. The intermediate temperature may be a temperature between the first temperature and a second temperature higher than the first temperature. If the temperature change rate is greater than a threshold temperature change rate, the intermediate temperature may be set to a first value. If the temperature change rate is less than the threshold temperature change rate, the intermediate temperature may be set to a second value greater than the first value.

[0082] In one embodiment, the electronic device (101) can control the brightness level to a first level. Referring to FIG. 6A, in one embodiment, the display (210) can be controlled to a first level, a first intermediate brightness level, a second intermediate brightness level, or a second level. The first level can be a set maximum brightness level of the display (210) under outdoor natural light conditions. If a screen (310) having a brightness level corresponding to the first level is continuously displayed, the display (210) may overheat. The first level can be, for example, 1300 nit, and there is no limitation on the specific value. The electronic device (101) can control the brightness of the display (210) to the first level based on whether the conditions for operating in a high brightness mode are satisfied. The high brightness mode may be a setting for controlling the brightness level of the display (210) to a set maximum brightness level (or brightness exceeding 500 nit) under outdoor light conditions. Conditions for operating in the high brightness mode will be described later.

[0083] In one embodiment, the electronic device (101) may perform heat control to ensure the life of the electronic device (101) and the performance of a battery (e.g., battery (189) of FIG. 1). For example, the electronic device (101) may change the operating frequency of a processor (e.g., application processor) by referring to the clock of Table 1 based on measuring the temperature of the electronic device (101).

[0084] Table 1

[0085]

[0086] For example, the electronic device (101) may operate in a first mode (e.g., light mode) in a temperature range between 36 degrees and 38 degrees. The electronic device (101) may control the AP frequency based on the first clock control in the first mode. The electronic device (101) may not perform brightness control (or brightness change for heat control) in the first mode. The electronic device (101) may operate in a second mode (e.g., moderate mode) in a temperature range between 39 degrees and 40 degrees. The electronic device (101) may operate based on the second clock control in the second mode. The electronic device (101) may reduce the brightness of the display to 400 nits based on the temperature of the electronic device (101) reaching 40 degrees. If the electronic device (101) immediately reduces the brightness of the display to 400 nits, the brightness of the screen displayed through the display may be drastically reduced. The electronic device (101) may operate in a third mode (e.g., severe mode) in a temperature range of 41 degrees to 43 degrees. The electronic device (101) may operate in the third mode based on a third clock control. The electronic device (101) may operate in a fourth mode (e.g., critical mode) in a temperature range of 44 degrees to 47 degrees. The electronic device (101) may operate in the fourth mode based on the fourth clock control. The electronic device (101) may reduce the brightness of the display to 300 nits based on the temperature of the electronic device (101) reaching 41 degrees.

[0087] Referring back to FIG. 6A, the brightness of the screen (610) having a brightness level corresponding to the first intermediate brightness level may be lower than the brightness of the screen (310) having a brightness level corresponding to the first level. The first intermediate brightness level may be 1100 nits, without limitation thereto. The brightness of the screen (620) having a brightness level corresponding to the second intermediate brightness level may be lower than the brightness of the screen (610) having a brightness level corresponding to the first intermediate brightness level. The second intermediate brightness level may be 900 nits, without limitation thereto. The brightness of the screen (320) having a brightness level corresponding to the second level may be lower than the brightness of the screen (620) having a brightness level corresponding to the second intermediate brightness level. The second level may be 400 nits, without limitation thereto. Referring to FIG. 6B, in one embodiment, the current consumption of the display corresponding to the brightness may increase as the brightness increases. The amount of current consumed (603) when the display is controlled to the first intermediate brightness level may be less than the amount of current consumed (601) when the display is controlled to the first level. The amount of current consumed (605) when the display is controlled to the second intermediate brightness level may be less than the amount of current consumed (603) when the display is controlled to the first intermediate brightness level. The amount of current consumed (607) when the display is controlled to the second level may be less than the amount of current consumed (605) when the display is controlled to the second intermediate brightness level. When the display operates at the first level, a high voltage and a high amount of current (601) may be required. When the display operates at the first level for a long period of time, heat generation of the display may occur. Instead of directly reducing the brightness level of the display from the first level to the second level, the electronic device (101) may reduce the brightness level of the display from the first level to at least one intermediate brightness level to ensure readability.For example, the electronic device (101) may reduce the brightness level of the display from a first level to a first intermediate brightness level based on the occurrence of heat generation in the display (or the electronic device (101)). The electronic device (101) may also reduce the brightness level of the display from the first level to a second intermediate brightness level. The electronic device (101) may reduce the brightness level of the display to the second level if the temperature of the electronic device (101) continues to rise due to the display being continuously controlled to at least one intermediate brightness level.

[0088] In one embodiment, when the display is controlled to an intermediate brightness level, the current consumption may be less than the current consumption when the display is controlled to a first level. By controlling the brightness level of the display to an intermediate brightness level, the electronic device (101) can display a screen with a high brightness level for a long period of time. Referring to FIG. 6C, in one embodiment, the electronic device (101) can control the brightness level of the display to 1300 nits (631). When the display is driven at 1300 nits for a long period of time, the temperature of the electronic device (101) may rise. The electronic device (101) can abruptly reduce the brightness level of the display to 400 nits (635) at a point in time (630) when the temperature of the electronic device (101) reaches a threshold temperature for performing heat generation control. The electronic device (101) can rapidly increase (637) the brightness level of the display to 1300 nits based on the temperature of the electronic device (101) decreasing below the threshold temperature for performing heat control. In one embodiment, the electronic device (101) can control the brightness level of the display to 900 nits (641). If the display is driven at 900 nits for a long period of time, the temperature of the electronic device (101) may rise. The electronic device (101) can reduce the brightness level of the display to 400 nits at the point in time (640) when the temperature of the electronic device (101) reaches the threshold temperature for performing heat control. If the brightness of the display is controlled to be low, the point in time for entering heat control can be delayed. For example, when the brightness of the display is controlled to 900 nits, the time period (643) required to enter heat control may be longer than the time period (633) required to enter heat control when the brightness of the display is controlled to 1300 nits.

[0089] In one embodiment, the electronic device (101) may determine an intermediate temperature for reducing the brightness level of the display to an intermediate brightness between the first brightness and a second brightness lower than the first brightness when the temperature of the electronic device (101) reaches a first temperature. As described with reference to FIGS. 6A, 6B, and 6C, the electronic device (101) may reduce the brightness level of the display from the first level to the intermediate brightness level instead of directly reducing the brightness level of the display from the first level to the second level to ensure readability under outdoor lighting conditions, based on the fact that the time period required until entering heat control (or until the temperature of the electronic device reaches a temperature indicating that the electronic device is in a heat-generating state) may be relatively long when controlling the brightness of the display to the intermediate brightness. The electronic device (101) may determine an intermediate temperature for reducing the brightness level of the display to the intermediate brightness level, for example, based on the temperature of the electronic device (101) reaching the first temperature. For example, the electronic device (101) may reduce the brightness level of the display from a third temperature between the first temperature and the second temperature when the temperature change rate of the electronic device (101) is low. The first temperature, the second temperature, or the third temperature may be replaced with terms such as first threshold temperature, second threshold temperature, or third threshold temperature.

[0090] In one embodiment, the electronic device (101) can check the temperature change rate within a specified time interval and, based on the checked temperature change rate, determine an intermediate temperature for reducing the brightness of the display to an intermediate brightness. The temperature change rate can represent the amount of temperature change during the set time interval. Referring to FIG. 7A, the electronic device (101) can check the amount of temperature change of the electronic device (101) during the set time interval (701). While the electronic device (101) controls the brightness level of the display to a maximum brightness level set for an outdoor light environment, the temperature change rate of the electronic device (101) can vary depending on the operating conditions of the electronic device (101). For example, when the electronic device (101) performs an operation requiring high power, the temperature change rate (711) of the electronic device (101) can be greater than a threshold temperature change rate (703). When the electronic device (101) performs an operation requiring low power, the temperature change rate (721) of the electronic device (101) may be less than a threshold temperature change rate (703). If the temperature change rate is greater than the threshold temperature change rate, the intermediate temperature may be determined as a first value. The first value may be a first temperature, without limitation thereto. If the temperature change rate is less than the threshold temperature change rate, the intermediate temperature for reducing the brightness level of the display to an intermediate brightness may be set to a second value greater than the first value. The second value may be, for example, a third temperature, without limitation thereto.

[0091] Referring again to FIG. 5, at operation 503, in one embodiment, the electronic device (101) may reduce the brightness level of the display to a medium brightness level when the current temperature of the electronic device (101) reaches a medium temperature.

[0092] Referring to FIG. 7B, in one embodiment, the electronic device (101) may initiate brightness control at an early point in time based on whether the temperature change rate of the electronic device (101) is greater than a threshold temperature change rate. For example, the electronic device (101) may reduce the brightness level of the display from 1300 nits to 1100 nits after the time point (741) when the electronic device (101) reaches a first temperature (or, at the time the first temperature is reached). The electronic device (101) may reduce the brightness level of the display to a first intermediate brightness level (733) that is less than the first level (731) based on whether the temperature change rate is greater than the threshold temperature change rate. The temperature change rate may be a temperature change rate measured after the temperature of the electronic device (101) reaches the first temperature. The temperature change rate may also be a temperature change rate measured immediately before the temperature of the electronic device (101) reaches the first temperature. The temperature change rate may be a temperature change rate measured when the temperature of the electronic device (101) is lower than a first temperature. In one embodiment, the electronic device (101) may determine a policy for reducing the brightness level of the display using the temperature change rate determined based on the temperature of the electronic device (101) reaching the first temperature. In one embodiment, the electronic device (101) may determine a policy for reducing the brightness level of the display using one or more temperature change rates that are periodically determined while the temperature of the electronic device (101) sequentially increases after the temperature of the electronic device (101) reaches the first temperature. The electronic device (101) may reduce the brightness of the display to a second intermediate brightness level (735) at a time point (743) when the electronic device (101) reaches a third temperature based on the temperature change rate being greater than a threshold temperature change rate. The electronic device (101) can reduce the brightness level of the display to a second level (737) at a point (745) when the electronic device (101) reaches a second temperature based on the temperature change rate being greater than a threshold temperature change rate.

[0093] Continuing with reference to FIG. 7B, in one embodiment, the electronic device (101) may reduce the brightness level of the display to a first intermediate brightness level (733) when the temperature of the electronic device (101) reaches a third threshold temperature higher than the first temperature (751) based on the temperature change rate being less than the threshold temperature change rate. The electronic device (101) may reduce the brightness level of the display to a second level (737) when the electronic device (101) reaches a second temperature (753) based on the temperature change rate being less than the threshold temperature change rate.

[0094] In one embodiment, a change pattern of a luminance level when the temperature change rate of the electronic device (101) is lower than a threshold change rate may be different from a change pattern of a luminance level when the temperature change rate of the electronic device (101) is higher than the threshold change rate. For example, a time period (755) during which the electronic device (101) can operate at a high luminance level (e.g., the first level (731) and the first intermediate luminance level (733)) when the temperature change rate of the electronic device (101) is lower than the threshold change rate may be longer than a time period (747) during which the electronic device (101) can operate at a high luminance level (e.g., the first level (731), the first intermediate luminance level (733), and the second intermediate luminance level (755)) when the temperature change rate of the electronic device (101) is higher than the threshold change rate. The electronic device (101) can secure visibility in a high-brightness mode and increase the time period in which the display can operate at a high brightness level based on reducing the brightness level of the display to an intermediate brightness level (e.g., a first intermediate brightness level (733) or a second intermediate brightness level (735)) before the temperature of the electronic device (101) reaches a second temperature. The number of intermediate brightness levels for securing visibility in a high-brightness mode is not limited to the example of FIG. 7B. For example, the electronic device (101) can control the brightness level of the display so that the brightness of the display appears to change at a slow rate based on sequentially reducing the brightness level of the display to three or more intermediate brightness levels between the first level (731) and the second level (737). The electronic device (101) can reduce the possibility of deterioration of the user experience due to rapid brightness changes based on reducing the brightness level of the display to an intermediate brightness level.

[0095] Referring back to FIG. 5, in operation 505, in one embodiment, the electronic device (101) may reduce the brightness level of the display to a second level when the current temperature of the electronic device (101) reaches a second temperature. The second level may have no numerical limitation as long as it is a brightness level set to control heat generation of the electronic device (101). Referring to FIG. 8, in one embodiment, the electronic device (101) may reduce the brightness level of the display according to a plurality of time intervals (813) such that the brightness level of the display is controlled equally during one or more adjacent time points (821, 822, 823, 824, 825, 826, 827, 828, 829, 830, 831, 832) among the plurality of time intervals (813) based on the temperature of the electronic device (101) reaching the first temperature. For example, the electronic device (101) may reduce the brightness level of the display to an intermediate brightness level (811) based on the temperature of the electronic device (101) reaching an intermediate temperature set to ensure visibility in a high brightness mode. The electronic device (101) may control the brightness level of the display so that the brightness level of the display remains the same at the intermediate brightness level (811) for adjacent points in time. The electronic device (101) may control the display to be driven at a high brightness level for a long time period (813) based on reducing the brightness level of the display to the intermediate brightness level as the temperature of the electronic device (101) increases. For example, the time period (801) during which the display can be operated at a high brightness level when continuously operating at a set maximum brightness level without going through an intermediate brightness level may be shorter than the time period (813) when going through an intermediate brightness level.

[0096] FIG. 9 is a flowchart illustrating an example method for controlling a brightness level of a display of an electronic device according to various embodiments.

[0097] Referring to FIG. 9, in operation 901, in one embodiment, the electronic device (101) (e.g., the processor (250) of FIG. 2) can check the temperature of the electronic device (101).

[0098] In operation 903, in one embodiment, the electronic device (101) may determine whether the temperature is below a first temperature. The first temperature may be, for example, 36 degrees, but there is no limitation on the specific numerical value. Based on determining that the temperature is below the first temperature (operation 903 - Yes), the electronic device (101) may set the brightness of the display to 1300 nits in operation 905.

[0099] In one embodiment, based on determining that the temperature is greater than or equal to the first temperature (operation 903 - No), in operation 907, the electronic device (101) may determine whether the temperature is less than a third temperature that is higher than the first temperature. The third temperature may be, for example, 37 degrees, and there is no limitation on the specific numerical value. Based on determining that the temperature is less than the third temperature (operation 907 - Yes), the electronic device (101) may determine a case corresponding to the temperature change rate of the electronic device (101) in operation 909. For example, the electronic device (101) may determine a case corresponding to the temperature change rate according to Table 2.

[0102] In one embodiment, the temperature change rate may be measured in a cycle of 20 seconds. In one embodiment, the electronic device (101) may determine a policy for changing the brightness level based on the determined temperature change rate based on the temperature of the electronic device (101) reaching 36 degrees. For example, the electronic device (101) may set the brightness of the display to 1300 nits in operation 905 based on the temperature change rate being less than 1 degree at a temperature greater than or equal to 36 degrees and less than or equal to 37 degrees (the first case, the second case, and the third case). The electronic device (101) may set the brightness of the display to 1100 nits in operation 911 based on the temperature change rate exceeding 1 degree at a temperature greater than or equal to 36 degrees and less than or equal to 37 degrees. In one embodiment, the electronic device (101) may determine a brightness level change policy based on one or more temperature change rates measured periodically while the temperature of the electronic device (101) is rising.

[0103] In one embodiment, based on determining that the temperature is greater than or equal to a third temperature (operation 907-No), the electronic device (101) may determine, in operation 913, whether the temperature is less than or equal to a fourth temperature that is greater than the third temperature. The fourth temperature may be, for example, 38 degrees, and there is no limitation on the specific numerical value. Based on determining that the temperature is less than the fourth temperature (operation 913-Yes), the electronic device (101) may determine, in operation 915, a case corresponding to a temperature change rate of the electronic device (101). For example, based on determining that the temperature change rate is less than 0.6 degrees (case 1, case 2) at a temperature greater than or equal to 37 degrees and less than or equal to 38 degrees, the electronic device (101) may set the brightness level of the display to 1300 nits in operation 905. The electronic device (101) can set the brightness level of the display to 1100 nits at operation 911 based on a temperature change rate of between 0.6 and 1.0 degrees at a temperature of 37 degrees or more and less than 38 degrees (third case). The electronic device (101) can set the brightness level of the display to 900 nits at operation 917 based on a temperature change rate of more than 1.0 degrees at a temperature of 37 degrees or more and less than 38 degrees.

[0104] In one embodiment, based on determining that the temperature is greater than or equal to a fourth temperature (operation 913-No), the electronic device (101) may determine, in operation 919, whether the temperature is less than or equal to a fifth temperature that is greater than the fourth temperature. The fifth temperature may be, for example, 39 degrees, and there is no limitation on the specific numerical value. Based on determining that the temperature is less than or equal to the fifth temperature (operation 919-Yes), the electronic device (101) may determine, in operation 921, a case corresponding to a temperature change rate of the electronic device (101). For example, based on determining that the temperature change rate is less than or equal to 0.2 degrees (first case) at a temperature greater than or equal to 38 degrees and less than or equal to 39 degrees, the electronic device (101) may set the brightness level of the display to 1300 nits in operation 905. The electronic device (101) can set the brightness level of the display to 1100 nits in operation 911 based on a temperature change rate of between 0.2 and 0.6 degrees at a temperature of 38 degrees or more and less than 39 degrees (second case). The electronic device (101) can set the brightness level of the display to 900 nits in operation 917 based on a temperature change rate of more than 0.6 degrees at a temperature of 38 degrees or more and less than 39 degrees (third case, fourth case).

[0105] In one embodiment, based on determining that the temperature is greater than or equal to a fifth temperature (operation 919-No), the electronic device (101) may determine, in operation 923, whether the temperature is less than a second temperature that is higher than the fifth temperature. The second temperature may be, for example, 40 degrees, and there is no limitation on the specific numerical value. Based on determining that the temperature is less than the second temperature (operation 923-Yes), the electronic device (101) may determine, in operation 925, a case corresponding to a temperature change rate of the electronic device (101). For example, based on determining that the temperature change rate is less than or equal to 0.2 degrees (first case) at a temperature greater than or equal to 39 degrees and less than or equal to 40 degrees, the electronic device (101) may set the brightness level of the display to 1100 nits in operation 911. The electronic device (101) can set the brightness level of the display to 900 nits in operation 917 based on a temperature change rate exceeding 0.2 degrees at a temperature of 39 degrees or more and less than 40 degrees (second case, third case, fourth case).

[0106] In one embodiment, based on determining that the temperature is greater than or equal to the second temperature (operation 923-No), the electronic device (101) may, in operation 927, set the brightness level of the display to 400 nits.

The condition for operating in the high-brightness mode may also include that a high-brightness mode function is set to be activated.

[0109] In operation 1003, in one embodiment, the electronic device (101) may control the brightness level of the display (210) to a first level based on confirmation that the condition for operating in the high brightness mode is satisfied.

[0110] In operation 1005, in one embodiment, the electronic device (101) can determine the current surface temperature of the display (210) based on a temperature acquired using at least one sensor (220) while controlling the brightness level of the display (210) to a first level.

[0111] In operation 1007, in one embodiment, the electronic device (101) may determine an intermediate temperature for reducing the brightness level of the display (210) to an intermediate brightness level based on the current surface temperature reaching a first temperature and the temperature change rate exceeding a threshold temperature change rate.

The electronic device (101) may initiate brightness control at the time point (1123) when the current surface temperature reaches the first temperature. The electronic device (101) may also utilize the temperature change rate determined before the current surface temperature reaches the first temperature to reduce the brightness level of the display at the time point (1123) when the current surface temperature reaches the first temperature. The electronic device (101) may, for example, reduce the brightness level of the display to a first intermediate brightness level. The electronic device (101) may reduce the brightness level of the display to a second intermediate brightness level at a time point (1125) when it is determined that the temperature change rate (1111) exceeds the threshold temperature change rate (1101) and the current surface temperature reaches a third temperature (T_th3). The electronic device (101) may reduce the brightness level of the display to a second level at a time point (1127) when it is determined that the temperature change rate (1111) exceeds the threshold temperature change rate (1101) and the current surface temperature reaches a second temperature (T_th2).

FIG. 13 is a graph illustrating an example method for controlling the brightness level of a display of an electronic device according to various embodiments.

[0113] In operation 1201, in one embodiment, the electronic device (101) (e.g., the processor (250) of FIG. 2) may control the brightness level of the display to a first level. The electronic device (101) may set the brightness level of the display to a maximum brightness level, for example, based on ambient light exceeding a threshold illuminance in a high brightness mode.

[0114] In operation 1203, in one embodiment, the electronic device (101) may reduce the brightness level of the display to a first intermediate brightness level set to ensure the visibility of the display (210) in a high brightness mode based on the current surface temperature reaching a first temperature and the temperature change rate exceeding a threshold temperature change rate. Referring to FIG. 13, the electronic device (101) may reduce the brightness level of the display to the first intermediate brightness level based on the temperature change rate exceeding the threshold temperature change rate at a time point (1311) when the current surface temperature reaches the first temperature. In one embodiment, the temperature change rate may be a temperature change rate measured at a time point (1311) when the current surface temperature reaches the first temperature. The temperature change rate may also be a temperature change rate measured before the current surface temperature reaches the first temperature. The temperature change rate may also be any one of one or more temperature change rates measured based on a set cycle while the surface temperature of the electronic device (101) is rising.

[0115] In operation 1205, in one embodiment, the electronic device (101) may reduce the brightness level of the display (210) to a second intermediate brightness level lower than the first intermediate brightness level based on the current surface temperature reaching a third temperature higher than the first temperature.

[0116] In one embodiment, the electronic device (101) may reduce the brightness level of the display (210) to a second intermediate brightness level based on the current surface temperature and the temperature change rate. Referring to FIG. 13, the electronic device (101) may reduce the brightness of the display to the second intermediate brightness based on the temperature change rate exceeding a threshold temperature change rate at a time point (1313) when the current surface temperature reaches a third temperature. In one embodiment, the temperature change rate that the electronic device (101) refers to to control the brightness level of the display may be the temperature change rate measured at a time point (1311) when the surface temperature of the electronic device (101) reaches the first temperature. The temperature change rate may also be the temperature change rate measured at a time point when the surface temperature reaches the third temperature. The temperature change rate may be any one of one or more temperature change rates measured based on a set cycle while the surface temperature of the electronic device (101) sequentially increases to the third temperature.

[0117] In operation 1207, in one embodiment, the electronic device (101) may reduce the brightness level of the display (210) to a second level based on the current surface temperature reaching the second temperature.

[0120] Referring to FIG. 14, in operation 1401, in one embodiment, the electronic device (101) (e.g., the processor (250) of FIG. 2) may determine whether the temperature and the temperature change rate of the electronic device (101) satisfy a condition for reducing the brightness level of the display (210) based on a time interval set to periodically check the temperature change rate. The electronic device (101) may determine whether to reduce the brightness level of the display based on, for example, checking the brightness level set in response to the temperature and the temperature change rate of the electronic device (101).

[0121] In operation 1403, in one embodiment, the electronic device (101) may reduce the brightness level of the display (210) based on determining that the temperature and temperature change rate satisfy the above conditions.

[0122] In operation 1405, in one embodiment, the electronic device (101) may maintain the brightness level of the display (210) based on determining that the temperature and the temperature change rate do not satisfy the above conditions. At least some of operations 1401 to 1405 may be performed at set intervals to determine the temperature change rate. In one embodiment, the electronic device (101) may control the brightness level of the display to brightness levels corresponding to specified temperatures based on a temperature change rate measured based on the temperature of the electronic device (101) reaching a first temperature, instead of one or more temperature change rates that are determined periodically. For example, the electronic device (101) may determine a policy for decreasing the brightness level of the display when the temperature of the electronic device (101) reaches the first temperature, and control the brightness level of the display based on the determined policy until the temperature of the electronic device (101) reaches the second temperature.

[0123] FIG. 15 is a flowchart illustrating an example method for controlling the brightness level of a display of an electronic device according to various embodiments. FIG. 15 will be described with reference to FIG. 16. FIG. 16 is a graph illustrating an example method for controlling the brightness level of a display of an electronic device according to various embodiments.

[0124] Referring to FIG. 15, in operation 1501, in one embodiment, the electronic device (101) (e.g., the processor (250) of FIG. 2) may control the brightness level of the display to a first level.

[0125] In operation 1503, in one embodiment, the electronic device (101) may reduce the brightness level of the display to an intermediate level. Referring to FIG. 16, the electronic device (101) may reduce the brightness level of the display from a first level (1601) to a first intermediate brightness level (1603) based on a temperature change rate being less than a threshold temperature change rate at a time point (1611) when the temperature of the electronic device (101) reaches a third temperature higher than the first temperature.

[0126] In operation 1505, in one embodiment, the electronic device (101) may reduce the brightness level of the display to a second level. The electronic device (101) may reduce the brightness level of the display to the second level (1605) based on a temperature change rate being less than a threshold temperature change rate at a time point (1613) when the temperature of the electronic device (101) reaches the second temperature.

[0127] In operation 1507, in one embodiment, the electronic device (101) may determine whether the temperature decreases below the second temperature after reducing the brightness level of the display (210) to the second level.

[0128] In one embodiment, based on determining that the temperature does not decrease below the second temperature (operation 1507-No), the electronic device (101) may, in operation 1509, set the brightness level of the display to a brightness level for heat control. The electronic device (101) may, for example, maintain the brightness level of the display at the second level.

[0129] In one embodiment, based on determining that the temperature decreases below the second temperature (operation 1507 - Yes), the electronic device (101) may, in operation 1511, change the brightness level of the display (210) to a brightness level set in response to the temperature and the temperature change rate. Referring to FIG. 16 , the electronic device (101) may increase the brightness level of the display to a first intermediate brightness level (1603) at the point in time (1615) when the temperature decreases below the second temperature.

[0130] FIG. 17A is a flowchart illustrating an example method for setting an intermediate temperature for controlling the brightness level of a display of an electronic device according to various embodiments. FIG. 17A will be described with reference to FIG. 17B. FIG. 17B is a diagram illustrating a prediction method for identifying a grip event of an electronic device according to various embodiments.

[0131] Referring to FIG. 17A, in operation 1701, in one embodiment, the electronic device (101) (e.g., the processor (250) of FIG. 2) may determine a temperature change rate of the electronic device (101). The electronic device (101) may determine the temperature change rate of the electronic device, for example, based on the temperature of the electronic device (101) reaching a first temperature. In one embodiment, the electronic device (101) may determine information associated with a grip event of the electronic device (101) based on a sensing value obtained through a grip sensor (e.g., the grip sensor (176)) in operation 1703. In one embodiment, the electronic device (101) may determine that the electronic device (101) is gripped by a user as a grip event of the electronic device (101). The electronic device (101) may determine that the electronic device (101) is gripped, for example, based on a sensing value of the grip sensor.

[0132] In one embodiment, the electronic device (101) may determine an intermediate temperature based on the identified temperature change rate and information associated with the grip event at operation 1705. If the temperature change rate is greater than the threshold temperature change rate and no grip event occurs, the intermediate temperature may be set to a third value greater than the first value. For example, the electronic device (101) may determine the intermediate temperature as a temperature higher than the set intermediate temperature (e.g., 37 degrees, 38 degrees, or 39 degrees).

[0133] Referring to FIG. 17B, in one embodiment, the electronic device (101) can improve usability by changing the setting of the threshold temperature based on the usage environment of the electronic device (101) (e.g., whether the electronic device (101) is gripped). Referring to reference numeral 1710, the electronic device (101) can change the setting of the temperature so that the temperature for reducing the brightness level of the display to the second level is higher than the second temperature (e.g., 40 degrees) when the electronic device (101) is not gripped. The electronic device (101) can also use the front camera (1711) to determine the occurrence of an event for changing the setting of the threshold temperature. Referring to reference numeral 1720, the electronic device (101) can maintain the setting of the threshold temperature based on determining that the electronic device (101) is in contact with the user's body (1721).

[0134] FIG. 18A is a flowchart illustrating an example method for setting an intermediate temperature for controlling the brightness level of a display of an electronic device according to various embodiments. FIG. 18A will be described with reference to FIG. 18B. FIG. 18B is a graph illustrating an example current consumption according to the operation of an electronic device according to various embodiments.

[0135] Referring to FIG. 18A, in operation 1801, in one embodiment, the electronic device (101) (e.g., the processor (250) of FIG. 2) may determine a temperature change rate of the electronic device (101). The electronic device (101) may determine the temperature change rate of the electronic device, for example, based on the temperature of the electronic device (101) reaching a first temperature.

[0136] In one embodiment, the electronic device (101) may, in operation 1803, identify information associated with the currently running application. In one embodiment, the electronic device (101) may identify identification information of the currently running application. For example, the electronic device (101) may identify the package name of the application running in the foreground. The electronic device (101) may also identify the type of the currently running application. For example, the type of application may include an Internet browser, a streaming application, or a navigation application.

[0137] In one embodiment, the electronic device (101) may determine an intermediate temperature based on information associated with a currently running application and the identified temperature change rate at operation 1805. If the temperature change rate is greater than a threshold temperature change rate and the currently running application is a designated application, the intermediate temperature may be set to a third value greater than the first value. For example, if the currently running application is a navigation application, the electronic device (101) may determine the intermediate temperature as a temperature higher than the set intermediate temperature (e.g., 37 degrees, 38 degrees, or 39 degrees).

[0138] Referring to FIG. 18B, the current consumption (1811) when providing a navigation service may be greater than the current consumption (1813) when the electronic device (101) is in an idle state. The idle state may include a state in which the electronic device (101) provides a home screen. The electronic device (101) may change the setting of the threshold temperature based on the fact that heat generation may occur in an environment in which the navigation service is used (e.g., when a grip event of the electronic device (101) does not occur). The electronic device (101) may also increase each of the first temperature, the third temperature, the fourth temperature, the fifth temperature, and the second temperature by 1 degree.

[0139] FIG. 19 is a flowchart illustrating an example method for setting a threshold temperature for controlling a brightness level of a display of an electronic device according to various embodiments.

[0140] Referring to FIG. 19, in operation 1901, in one embodiment, the electronic device (101) (e.g., the processor (250) of FIG. 2) may determine whether a shape of a user of the electronic device (101) is recognized in an image acquired through a camera (230) of the electronic device (101). The electronic device (101) may determine whether a facial shape is identified in a preview image acquired using, for example, a front camera. The electronic device (101) may also determine whether a touch event is identified.

[0141] In one embodiment, based on determining that the user's shape is recognized (operation 1901 - Yes), the electronic device (101) may, in operation 1903, maintain a setting of a threshold temperature for determining that the state of the electronic device is overheated.

[0142] In one embodiment, based on determining that the user's shape is not recognized within the image (operation 1901-No), the electronic device (101) may, at operation 1905, change the setting of the threshold temperature for determining that the electronic device (101) is overheated to a temperature higher than the second threshold temperature.

[0146] In one embodiment, based on determining that the display is folded (operation 2003-Yes), the electronic device (101) may, in operation 2005, set a luminance level corresponding to each of the plurality of regions of the display (210) such that a luminance level of a first region among the plurality of regions is different from a luminance level of a second region among the plurality of regions, which is different from the first region. The first region may be, for example, a region in which an amount of light incident on the first region exceeds a set threshold illuminance.

[0147] In one embodiment, upon determining that the display is not folded (operation 2003-No), the electronic device (101) may, at operation 2007, set the brightness level of the display (210) such that the brightness level corresponding to each of the plurality of regions is the same.

The electronic device (101) may include a display (e.g., the display (210) of FIG. 2). The electronic device (101) may include at least one processor (e.g., the processor (250)) including a processing circuit. The electronic device (101) may include a memory (e.g., the memory (240) of FIG. 2) that stores instructions. The instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to: determine a temperature change rate within a specified time interval based on a temperature of the electronic device (101) reached by the at least one sensor (220) based on an ambient light level where the brightness level of the display (210) is set to a first level; and determine an intermediate temperature between the first temperature and a second temperature higher than the first temperature based on the determined temperature change rate to reduce the brightness level of the display (210) to an intermediate brightness level between the first level and a second level lower than the first level. The intermediate temperature may be set to a first value based on the temperature change rate being greater than a threshold temperature change rate. The intermediate temperature may be set to a second value greater than the first value based on the temperature change rate being less than the threshold temperature change rate. The above instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to reduce the brightness level of the display to the intermediate brightness level based on the current temperature of the electronic device (101) reaching the intermediate temperature.The above instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to reduce the brightness level of the display (210) to the second level based on the current temperature reaching the second temperature.

[0151] In an example embodiment, the instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to determine whether a condition for operating in a high brightness mode is satisfied based on an illuminance obtained through an illuminance sensor (176) of the electronic device (101) configured to measure an amount of light incident on the electronic device (101). The instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to control a brightness level of the display (210) to the first brightness level based on determining that the condition for operating in the high brightness mode is satisfied. The instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to determine a current surface temperature of the display (210) based on the temperature acquired using the at least one sensor (220) while controlling the brightness level of the display (210) to the first brightness level. The instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to determine an intermediate temperature as a first value for reducing the brightness level of the display (210) to the intermediate brightness level based on the current surface temperature reaching the first temperature and the temperature change rate exceeding the threshold temperature change rate.

[0152] In an example embodiment, the instructions, when individually or collectively executed by the at least one processor (250), may cause the electronic device (101) to reduce a brightness level of the display to a first intermediate brightness level set to ensure visibility of the display (210) in the high brightness mode based on the current surface temperature reaching the first temperature and the temperature change rate exceeding the threshold temperature change rate.
