For example, the resource manager 207 may manage the source code of the application 146 or the storage space of the memory 130. For example, the power manager 209 may manage the capacity, temperature, or power of the battery 189, and determine or provide relevant information for the operation of the electronic device 101 based at least in part on the corresponding information of the capacity, temperature, or power of the battery 189. According to an embodiment, the power manager 209 may interact with a basic input / output system (BIOS) (not shown) of the electronic device 101.

[0059] For example, the database manager 211 can generate, search or change the database to be used by the application 146. For example, the package manager 213 can manage the installation or update of applications distributed in the form of package files. For example, the connection manager 215 can manage the wireless connection or direct connection between the electronic device 101 and an external electronic device. For example, the notification manager 217 can provide a function of notifying the user of a specific event (e.g., an incoming call, message, or alarm). For example, the location manager 219 can manage the location information about the electronic device 101. For example, the graphic manager 221 can manage one or more graphic effects to be provided to the user or a user interface related to one or more graphic effects.

[0060] For example, the security manager 223 can provide system security or user authentication. For example, the phone manager 225 can manage the voice call function or video call function provided by the electronic device 101. For example, the voice recognition manager 227 can send the user's voice data to the server 108, and receive from the server 108 a command corresponding to a function executed on the electronic device 101 based at least in part on the voice data or at least in part on text data converted from the voice data. According to an embodiment, the middleware 244 can dynamically delete some existing components or add new components. According to an embodiment, at least a portion of the middleware 144 can be included as a part of the OS 142, or can be implemented as another software separated from the OS 142.

[0061] Applications 146 may include, for example, home 251, dialer 253, short message service (SMS) / multimedia message service (MMS) 255, instant messaging (IM) 257, browser 259, camera 261, alarm 263, contacts 265, voice dialing 267, email 269, calendar 271, media player 273, photo album 275, watch 277, health 279 (e.g., for measuring exercise level or bio-information, such as blood sugar) or environmental information 281 (e.g., for measuring air pressure, humidity or temperature information) applications. According to an embodiment, application 146 may further include an information exchange application (not shown) capable of supporting information exchange between electronic device 101 and an external electronic device. For example, the information exchange application may include a notification relay application suitable for transmitting specified information (e.g., call, message or alarm) to an external electronic device, or a device management application suitable for managing an external electronic device. The notification relay application can transmit notification information corresponding to the occurrence of a specified event (e.g., reception of an email) at another application (e.g., email application 269) of the electronic device 101 to the external electronic device. Additionally or alternatively, the notification relay application can receive notification information from the external electronic device and provide the notification information to the user of the electronic device 101.

[0062] The device management application may control the power (e.g., turning on or off) or function (e.g., adjustment of brightness, resolution, or focus) of the external electronic device or certain components thereof (e.g., a display device or camera module of the external electronic device). Additionally or alternatively, the device management application may support installation, deletion, or updating of applications running on the external electronic device.

[0065] refer to Figure 3 and Figure 4 , electronic devices (e.g. Figure 1 The electronic device 101 may include an activity manager 231, a codec manager 233, a display solution manager 235, and a power manager 209, each of which may include, for example, various executable program elements and may be included in a program stored in a memory (e.g., Figure 1 The electronic device (e.g., Figure 1 The electronic device 101 may further include a display driver 241, which may include, for example, various executable program elements and may be included in a program stored in a memory (eg, Figure 1 In the operating system 142 in the memory 130).

[0066] Electronic devices (e.g. Figure 1 A processor (eg, Figure 1 The processor 120 may include various processing circuits and may be read from a memory (e.g., Figure 1 The memory 130 of the electronic device may call at least one of one or more instructions stored in the activity manager 231, the codec manager 233, the display solution manager 235, the power manager 209, and the display driver 241, and may execute the called instructions. Hereinafter, a description of the instructions stored in the program will be described together with a description of an example operation of the electronic device.

[0067] The electronic device may determine whether a screen-off condition for turning off the screen of the electronic device is met. When a setting of the electronic device or a user's setting meets a specific condition, the electronic device may turn off the screen. According to an embodiment, when a first time passes without user input, the screen dims, and when a second time passes without user input, the screen turns off, and thus the electronic device enters a locked state. According to an embodiment, the electronic device may display a display setting menu for receiving a setting input for the display of the electronic device. The display setting menu may include, for example, a "screen auto-off time", and the screen-off condition of the electronic device may correspond to the setting value of the "screen auto-off time".

[0068] An instruction for determining whether the screen-off condition of the electronic device is satisfied may be stored in the display solution manager 235 , and the processor of the electronic device may determine whether the screen-off condition of the electronic device is satisfied through the display solution manager 235 .

[0069] When the screen off condition of the electronic device is met, the processor can perform a control operation to send a screen off instruction from the display solution manager 235 to the power manager 209, and can perform a control operation to send an instruction for the power manager 209 to set the screen brightness value to "0" to the display driver 241.

[0070] Even if the screen-off condition of the electronic device is satisfied, the electronic device may determine whether the screen of the electronic device is kept in the on state (401). According to an embodiment, an application (e.g., Figure 2 An application 146 of the electronic device may request the power manager 209 of the electronic device to keep the screen in the on state. According to an embodiment, an application (e.g., a moving image reproduction application, a game application, or a browser application) that may request the screen to be kept in the on state may send a wake-up lock request to the power manager 209 to keep the screen in the on state. Therefore, even if the screen off condition of the electronic device is met, the power manager 209 may perform a control operation so that the screen of the electronic device is kept in the on state.

[0071] Even if the screen off condition of the electronic device is met, the electronic device may determine whether a specific time 'a' has passed while the screen of the electronic device is kept on (402). According to an embodiment, the specific time 'a' may be determined by the setting of the electronic device. For example, but not limited to, the specific time 'a' may be 10 minutes.

[0072] Even if the screen off condition of the electronic device is satisfied, when a specific time 'a' elapses while the screen of the electronic device is maintained in the on state, the electronic device may determine whether the first screen code value is greater than a specific value 'b' ( 403 ).

[0073] Will refer to Figure 5 and Figure 7 Describe the first screen code value. According to an embodiment, the screen 501 of the display panel of the electronic device may display a bar (brightness adjustment bar) 502 for controlling the brightness of the screen 501. The brightness adjustment bar 502 may correspond to the first screen code. According to an embodiment, the first screen code may, for example, have a value in the range of 0 to 255, the left end of the brightness adjustment bar 502 may correspond to the first screen code value "0", and the code value may increase to the right, so the right end of the brightness adjustment bar 502 may correspond to the first screen code value "255". When the user 10 moves the cursor 503 of the brightness adjustment bar 502, the display solution manager 235 may send the first screen code value (for example, "128") corresponding to the cursor 503 to the power manager 209. The power manager 209 may use the value obtained by mapping the screen code value to the brightness value (nit) of the screen. Figure 6 The power manager 209 may identify the brightness value of the screen (screen brightness value) (e.g., 298 nits) corresponding to the first screen code value (e.g., 128) by using a graph of the power manager 209. The power manager 209 may send the identified screen brightness value (e.g., 298 nits) to the display driver 241, and the display driver 241 may change the brightness of the screen to the identified screen brightness value (e.g., 298 nits). In other words, the user 10 may change the brightness value of the screen to correspond to the first screen code by moving the cursor 503 of the brightness adjustment bar 502. Figure 6 The graph is provided for illustrative purposes, and it should be understood that the manner of mapping the code value to the brightness value of the real screen and the unit representing the screen brightness value are not limited to Figure 6 The method shown.

[0074] refer to Figure 3 and Figure 4 , even if the screen-off condition of the electronic device is met, when a specific time "a" has passed while the screen of the electronic device is kept turned on, the electronic device may determine whether the first screen code value is greater than a specific value "b" (403). According to an embodiment, the specific value "b" may be determined based on the code value, and when the first screen code value is reduced to be equal to or less than the specific value "b", the brightness change at the code value becomes meaningless because the screen has no brightness change or is not recognized by the user's naked eye. According to an embodiment, the specific value "b" may be "122", for example. When the first screen code value is equal to or less than the specific value "b", the process may be terminated without controlling the screen brightness value.

[0075] When the first screen code value is greater than a specific value "b" ("Yes" in operation 403), the electronic device may set the code value obtained by reducing the first screen code value by a decrement to a second screen code value (404). In this case, the minimum decrement may be, for example, but not limited to, 1%. The second screen code value is not a value identified and changed by the user through the brightness adjustment bar 502, which is different from the first screen code value, but may be a value for controlling the screen brightness of the electronic device, which is similar to the first screen code value. According to an embodiment, even if the screen off condition of the electronic device is met, when the screen of the electronic device is kept in an on state, the second screen code value may also be a value for controlling the screen brightness. The first screen code value and the second screen code value may be independent of each other, and the first screen code value may be maintained even if the second screen code value changes.

[0076] When the initial value of the first screen code value is, for example, "230", the electronic device may set a code value, for example, "227.7", which is obtained by reducing the first screen code value "230" by 1%, as the second screen code value. The display solution manager 235 may send the set second screen code value "227.7" to the power manager 209. The power manager 209 may use Figure 6 The power manager 209 may identify a brightness value of the screen by using a graph of the screen code value, which corresponds to the second screen code value "227.7". The power manager 209 may send the identified screen brightness value to the display driver 241, and the display driver 241 may reduce the brightness of the screen to the identified screen brightness value. Although the second screen code value is changed to "227.7", the first screen code value may be maintained as "230".

[0077] When a certain time (eg, 1 minute) elapses after the brightness value of the screen is changed to correspond to the second screen code value ( 405 ), the electronic device may determine whether the decrement is less than the maximum decrement “C” ( 406 ).

[0078] In the following, reference will be made to Figure 7 Describe the maximum decrement "C". The first screen code value may have various maximum decrements "C" depending on the range. When the first screen code value corresponds to a value in the range of 110 to 118, the maximum decrement "C" may be, for example, 10%. When the first screen code value corresponds to a value in the range of 119 to 133, the maximum decrement "C" may be, for example, 15%. When the first screen code value corresponds to a value in the range of 134 to 255, the maximum decrement "C" may be, for example, 20%. For example, even if the screen-off condition of the electronic device is met, when the screen of the electronic device is kept on, the maximum decrement may also refer to the maximum value for reducing the brightness of the screen. Decrement based on the maximum decrement "C" for each screen code value Figure 7The mapping table is provided for illustration purposes and is not limited to Figure 7 In other words, according to the embodiment, modification is possible.

[0079] Reference again Figure 3 , Figure 4 and Figure 7 , the electronic device may determine whether the decrement is less than the maximum decrement "C" (406). When it is determined that the decrement is greater than or equal to the maximum decrement "C" ("No" in operation 406), the electronic device may terminate the process without controlling the screen brightness.

[0080] Assuming the first screen code value is "230", the electronic device can Figure 7 Table 700 is used to identify that the maximum decrement "C" is 20%. Since the initial decrement is 1%, the electronic device can determine that the decrement is less than the maximum decrement "C" of 20%.

[0081] When it is determined that the decrement is less than the maximum decrement “C” ( 407 ), the electronic device may determine whether an application running on the electronic device is switched or whether a hardware codec is used.

[0082] When the application running on the electronic device is switched, it is necessary to control the brightness of the screen according to the switched application. Therefore, the process of controlling the screen brightness according to the application before switching can be terminated. According to an embodiment, when the application running on the electronic device is switched, it can refer to when other applications are running, or when an input to the home key of the electronic device is received. When the application is switched, the activity manager 231 can broadcast information about the application switching, and the display solution manager 235 can receive information about the application switching to identify the switching of the application.

[0083] Alternatively, when the hardware codec of the electronic device is used, it is determined that a moving image is being reproduced on the application. Therefore, the brightness of the screen needs to be maintained, so the process of controlling the brightness of the screen can be terminated. According to an embodiment, the display solution manager 235 may request a response from the codec manager 233 as to whether the hardware codec is being used. In response to the request, the codec manager 233 may send a message to the display solution manager 235 as to whether the hardware codec is being used.

[0084] When the application running on the electronic device is not switched and the hardware codec is not used, the electronic device may increase the decrement by 1% (408), and may repeat the process starting from operation 404. According to an embodiment, the initial decrement is 1%, so the decrement is increased by 1% to become 2%, and the electronic device may update the second screen code value to a code value "225.4" obtained by reducing the first screen code value "230" by 2%.

[0085] The display solution manager 235 may send the updated second screen code value "225.4" to the power manager 209. The power manager 209 may use Figure 6 The power manager 209 may identify a screen brightness value corresponding to the second screen code value "225.4" by using a graph of the screen brightness value. The power manager 209 may send the identified screen brightness value to the display driver 241, and the display driver 241 may change the screen brightness to the identified screen brightness value. Although the second screen code value is changed to "225.4", the first screen code value may be maintained as "230".

[0086] Whenever a specific time (e.g., 1 minute) has passed after the brightness value of the screen has been changed to correspond to the second screen code value, the electronic device may update the second screen code value by applying a 1% decrement to the first screen code value. According to an embodiment, whenever a specific time (e.g., 1 minute) has passed, the electronic device may sequentially update the second screen code value to values ​​of "227.7", "225.4", "223.1", "220.8", ... and "184", which are obtained by reducing the first screen code value of "230" by 1%, 2%, 3%, 4%, ... and 20%. Whenever the second screen code value is sequentially updated to values ​​of "227.7", "225.4", "223.1", "220.8", ... and "184", the brightness of the screen may be gradually reduced.

[0087] According to an embodiment, when the decrement becomes 21% of the maximum decrement "C" greater than 20% as 21 minutes pass, the electronic device no longer updates the second screen code value and can terminate the process of controlling the screen brightness. Alternatively, when an application running on the electronic device is switched or a hardware codec is used in the electronic device, even if the decrement is not greater than the maximum decrement "C", the electronic device does not update the second screen code value and can terminate the process of controlling the screen brightness.

[0088] Figure 4 The flowcharts are provided for illustrative purposes, and according to embodiments, some operations may be omitted or some orders may be changed.

[0089] Although the embodiment is described under the assumption that the specific time in operation 405 is one minute, the specific time may be variously changed to one minute and 30 seconds, two minutes, and five minutes according to various embodiments. According to one embodiment, when the specific time in operation 405 is two minutes, the decrement may be reduced by 1% every two minutes.

[0090] Although the embodiment is described under the assumption that the decrement is 1%, according to various embodiments, the decrement may be increased by 2% or 3% differently. According to one embodiment, assuming that the specific time is two minutes and the decrement increases by 2%, the decrement may be increased by 2% every two minutes.

[0091] Will refer to Figure 8 Example effects according to the above-described embodiments are described.

[0092] refer to Figure 8 According to an embodiment, when the screen-off condition is that 10 minutes have passed without user input, and when the specific time "a" is 10 minutes, the electronic device can have a substantially constant power consumption of 20 minutes, which is the sum of the 10 minutes corresponding to the screen-off condition and the specific time "a" for keeping the screen in the on state when the screen-off condition is met.

[0093] When 20 minutes have passed, the electronic device may perform a process of controlling screen brightness. Assuming that the application is not switched or the hardware codec is not used, the electronic device may gradually reduce the screen brightness for 20 minutes before the reduction increases by 1% and is greater than the maximum reduction "C" of 20%. Therefore, the power consumption of the electronic device may gradually decrease over a duration of 20 to 40 minutes.

[0094] After the decrement increases to a maximum decrement "C" greater than 20%, the screen brightness may no longer be updated. Therefore, the power consumption of the electronic device may remain substantially constant for a duration after 40 minutes.

[0095] According to various embodiments of the present disclosure, even if the screen off condition of the electronic device is met, even if the screen of the electronic device remains on according to the request of the application, the electronic device can gradually reduce the brightness of the screen under certain conditions. Therefore, power consumption can be reduced, the user's eyesight can be protected, and the aging of the display can be prevented. In addition, such brightness of the screen can be performed gradually or substantially linearly, so that power consumption of the electronic device can be prevented, and the user will not feel uncomfortable with the change in screen brightness.

[0096] Reference Fig. 9 An example operation of the electronic device according to the embodiment is described.

[0097] Fig. 9 900 is a flowchart illustrating an example operation of an electronic device according to various embodiments. The same configuration and operation as described above are not repeated here.

[0098] refer to Fig. 9 Even if the screen-off condition of the electronic device is satisfied, the electronic device may determine whether the screen of the electronic device is maintained in the turned-on state (901).

[0099] Even if the screen-off condition of the electronic device is satisfied, the electronic device may determine whether a specific time 'a' has passed while the screen of the electronic device is kept turned on ( 902 ).

[0100] Even if the screen off condition of the electronic device is satisfied, when a specific time 'a' elapses while the screen of the electronic device is kept turned on, the electronic device may determine whether the first screen code value is greater than a specific value 'b' (903).

[0101] When the first screen code value is greater than a specific value "b" ("Yes" in operation 903), the electronic device may determine whether a browser application (eg, Figure 2 The browser application 259 of the electronic device and whether the hardware codec is used in the electronic device (904). When the browser application is executed, the activity manager 231 may broadcast that the browser application is executed. The display solution manager 235 may receive the broadcast and may recognize that the browser application is executed.

[0102] When it is determined that the browser application is executed in the electronic device and the hardware codec is used in the electronic device, the electronic device may terminate the process of controlling the screen brightness by determining that the moving image is reproduced on the browser application.

[0103] When it is determined that the browser application is executed in the electronic device and the hardware codec is not used in the electronic device, the electronic device may determine that the moving image is not reproduced in the browser application. The electronic device may set a code value obtained by reducing the first screen code value by a decrement as a second screen code value by determining that the browser application is executed in the electronic device and the hardware codec is not used in the electronic device (905).

[0104] When a certain time (e.g., 1 minute) has passed after the brightness value of the screen is changed to correspond to the second screen code value (906), the electronic device may determine whether the decrement is greater than or equal to the maximum decrement "C" (907). When the decrement is less than the maximum decrement "C" ("No" in operation 907), the electronic device may increase the decrement by 1% (operation 908), return to operation 904, and repeat the process from operation 904.

[0105] Fig. 9 The flowcharts are provided for illustrative purposes, and some operations may be omitted or the order may be changed according to embodiments.

[0106] Reference Fig.10 An example operation of the electronic device according to the embodiment is described.

[0107] Fig.101000 is a flowchart illustrating an example operation of an electronic device according to various embodiments. The same configuration and operation as described above are not repeated here.

[0108] exist Fig.10 In the embodiment, before determining whether the screen of the electronic device is turned on even if the screen-off condition of the electronic device is satisfied (1001), it is assumed that the second screen code value is adjusted to be smaller than the first screen code value according to other applications executed in the electronic device or specific conditions. According to the embodiment, it is assumed that the first screen code value is set to "230" and the second screen code value is set to "213.9", which is obtained by reducing the first screen code value by 7%.

[0109] refer to Fig.10 , even if the screen-off condition of the electronic device is satisfied, the electronic device may determine whether the screen of the electronic device is kept turned on ( 1001 ).

[0110] Even if the screen-off condition of the electronic device is satisfied, when the screen of the electronic device is turned on, the electronic device may determine whether a specific time “a” has passed while the screen of the electronic device remains turned on ( 1002 ).

[0111] Even if the screen-off condition of the electronic device is satisfied, when a specific time 'a' elapses while the screen of the electronic device remains on, the electronic device may determine whether the first screen code value is greater than a specific value 'b' ( 1003 ).

[0112] When the first screen code value is greater than a specific value "b" ("Yes" in operation 1003), the electronic device may determine that the browser application (eg, Figure 2 The browser application 259) is used in the electronic device and whether the hardware codec is not used (1004).

[0113] When a browser application is used in an electronic device and a hardware codec is not used, the electronic device may determine whether a value obtained by reducing a first screen code value by a decrement is equal to a second screen code value (1005). The minimum decrement may be 0%. According to an embodiment, it is assumed that the first screen code value is set to "230" and the second screen code value is set to "213.9" obtained by reducing the first screen code value by 7%. Therefore, the electronic device does not update the second screen code value (1007) for a certain time (e.g., 1 minute).

[0114] When a specific time (e.g., 1 minute) has passed, the electronic device may increase the decrement by 1% (1008), and may determine whether the decrement is greater than the maximum decrement "C" (1009). According to an embodiment, the electronic device may determine whether the decrement is less than the maximum decrement "C" because when the first screen code value is 230, the decrement increases from the minimum decrement 0% by 1% to 1%, and the maximum decrement "C" becomes 20%.

[0115] The electronic device may return to operation 1005, and may repeat the process starting from operation 1005 by determining that the decrement is less than the maximum decrement "C". According to an embodiment, when the decrement increases by 1% to 7% every certain time (e.g., 1 minute), the electronic device may determine that the code value "213.9" obtained by reducing the first screen code value "230" by 7% is equal to the second screen code value "213.9".

[0116] When it is determined that the code value obtained by reducing the first screen code value is equal to the second screen code value (1005), the electronic device may set the code value obtained by reducing the first screen code value to the second screen code value (1006). When the brightness of the screen changes to correspond to the set second screen code value and a specific time (e.g., 1 minute) has passed (1007), the electronic device may increase the decrement by 1% (1008), and may determine whether the decrement is greater than the maximum decrement "C" (1009). When the decrement is less than or equal to the maximum decrement "C", the electronic device returns to operation 1005 and repeats process operation 1005 until the decrement is greater than the maximum decrement "C".

[0117] Fig.10 The flowcharts are provided for illustrative purposes, and some operations may be omitted or the order may be changed according to embodiments.

[0118] According to an exemplary embodiment of the present disclosure, an electronic device includes: a display device, a processor operably connected to the display device, and a memory operably connected to the processor. The memory stores one or more instructions, which, when executed, cause the processor to: during a first specific time after a screen-off condition of the display device is satisfied, based on the screen being kept in an on state, determine a code value obtained by reducing a first screen code value relative to a brightness value of a screen of the display device as a second screen code value, and change the brightness value of the screen to correspond to the determined second screen code value.

[0119] The memory may also store one or more instructions that, when executed, cause the processor to change the decrement to increase the decrement until the decrement is equal to a specific value, and based on the decrement being changed, update the second screen code value to a code value obtained by reducing the first screen code value by the changed decrement.

[0120] The memory may also store one or more instructions that, when executed, cause the processor to maintain the first screen code value based on the brightness value of the screen being updated according to the second screen code value.

[0121] The memory may also store one or more instructions that, when executed, cause the processor to determine a specific value based on the first screen code value.

[0122] The condition for turning off the screen may include a second specific time passing without user input.

[0123] The memory may also store one or more instructions that, when executed, cause the processor to determine, as a changed decrement, a value obtained by increasing the decrement in proportion to the time elapsed after the brightness value of the screen is changed to correspond to the updated second screen code value.

[0124] The memory may also store one or more instructions that, when executed, cause the processor to determine a value obtained by increasing the decrement by 1% as a changed decrement based on a third specific time elapsed after the brightness value of the screen is changed to correspond to the updated second screen code value.

[0125] The memory may also store one or more instructions that, when executed, cause the processor to determine whether the browser application is being executed before updating the second screen code value.

[0126] The memory may also store one or more instructions that, when executed, cause the processor to determine whether a hardware codec is being used based on the browser application being executed.

[0127] The memory may also store one or more instructions which, when executed, cause the processor to: based on the first screen code value being different from the second screen code value at a point in time when the screen is kept in the on state during a first specific time after the screen-off condition is met, increase or decrease the second screen code value without updating the second screen code value until a code value obtained by decreasing the first screen code value by the decrement is equal to the second screen code value.

[0128] According to an example embodiment of the present disclosure, a method for controlling the brightness of a screen of an electronic device includes: determining a code value obtained by reducing or decrementing a first screen code value corresponding to a brightness value of the screen as a second screen code value based on the screen being kept in an on state during a first specific time after a screen-off condition is met; and changing the brightness value of the screen to correspond to the determined second screen code value.

[0129] The decrement may be changed to increase the decrement until the decrement is equal to a specific value, and based on the decrement being changed, the second screen code value is updated based on a code value obtained by reducing the first screen code value by the changed decrement.

[0130] The screen-based brightness value is updated according to the second screen code value, and the first screen code value may be maintained.

[0131] The specific value may be determined based on the first screen code value.

[0132] The screen-off condition may include a second specific time that has passed without user input.

[0133] A value obtained by increasing the decrement in proportion to the time elapsed after the brightness value of the screen is changed to correspond to the updated second screen code value may be determined as the changed decrement.

[0134] Based on the lapse of the third specific time after the brightness value of the screen is changed to correspond to the updated second screen code value, a value obtained by increasing the decrement by 1% may be determined as the changed decrement.

[0135] It may be determined whether the browser application is executed before the second screen code value is updated.

[0136] Based on the browser application being executed, it may be further determined whether a hardware codec is being used.

[0137] Based on the fact that the first screen code value is different from the second screen code value at a point in time when the screen is kept in the on state during a first specific time after the screen-off condition is met, the decrement can be increased without updating the second screen code value until the code value obtained by reducing the first screen code value by the decrement is equal to the second screen code value.

[0138] According to various exemplary embodiments of the present disclosure, in response to a request from an application running on an electronic device, the electronic device can be provided with the ability to reduce power consumption of the electronic device, prevent display burn-in, and protect the user's eyesight by controlling the brightness of the screen even if the electronic device keeps the screen on.
