DETAILED DESCRIPTION

FIG. 1 illustrates an exemplary electronic device.

Referring to FIG. 1, an electronic device 100 (e.g., an electronic device 901 of FIG. 9) may include a display 110 (e.g., a display module 960 of FIG. 9 or a display module 960 of FIG. 10). For example, the display 110 may display an image (e.g., an image 180 and/or an image 190) based on a current obtained from a power management integrated circuit (PMIC) (e.g., a power management module 988 of FIG. 9) of the electronic device 100 being driven based on a rated capacity.

For example, the image may be displayed at a brightness level within a first brightness range 160. For example, the first brightness range 160 may indicate a range from a first reference brightness level 161 to a second reference brightness level 162. For example, the first brightness range 160 may be higher than or equal to the first reference brightness level 161 and may be lower than or equal to the second reference brightness level 162.

For example, the second reference brightness level 162 may be a maximum brightness level that can be provided through the display 110, under the condition that on pixel ratio (OPR) of the image 180 is 100% (or 255), as in a state 170. The OPR may represent a ratio of at least one turned-on pixel versus a plurality of pixels in a display panel (e.g., a display panel 230 of FIG. 2) of the display 110. The OPR may represent an average value of a grayscale of the at least one pixel, but the disclosure is not limited thereto. For example, the second reference brightness level 162 may be the maximum brightness level that can be provided through the display 110 under the condition that a color of the entire area of the image 180 is white as in the state 170. For example, the second reference brightness level 162 may be a brightness level provided through the display 110 in a state in which the current I obtained from the PMIC, being driven based on the rated capacity, is the maximum current I_max.

For example, the image 190 displayed through the display 110 may have an OPR lower than the OPR of the image 180, as in the state 175. For example, when the image 180 is displayed on the display 110 at the second reference brightness level 162 which is the maximum brightness level of the first brightness range 160, the current I obtained from the PMIC may be the maximum current I_max, whereas when the image 190 is displayed on the display 110 at the second reference brightness level 162 which is the maximum brightness level of the first brightness range 160, the current I obtained from the PMIC may be less than the maximum current I_max. For example, the display 110 may cause, in displaying the image 190 at the second reference brightness level 162, heat lower than the heat generated from the display 110 when displaying the image 180 at the second reference brightness level 162. For example, the display 110 may have an ability to display the image 190 at a brightness level higher than the second reference brightness level 162.

For example, a second brightness range 165 may be used in the electronic device 100 to enhance the quality of the image 190 displayed through the display 110. For example, the second brightness range 165 may indicate a range from the first reference brightness level 161 up to the third reference brightness level 163, the third reference brightness level 163 being higher than the second reference brightness level 162. For example, the second brightness range 165 may indicate a range higher than or equal to the first reference brightness level 161 and lower than or equal to the third reference brightness level 163. For example, the maximum brightness level of the second brightness range 165 may be the third reference brightness level 163, unlike the first brightness range 160 having the second reference brightness level 162 as the maximum brightness level. For example, the second brightness range 165 may further include another range 166 reaching from the second reference brightness level 162 up to the third reference brightness level 163 in addition to the first brightness range 160.

For example, the second brightness range 165 (or the range 166) may be used when displaying an image having an OPR less than a maximum OPR (e.g., 100% or 255), such as the image 190. For example, the electronic device 100 may include components for providing the second brightness range 165. The above components may be illustrated referring to FIG. 2.

FIG. 2 is a simplified block diagram of an exemplary electronic device.

Referring to FIG. 2, the electronic device 100 may include a processor (e.g., including processing circuitry) 210 (e.g., a processor 920 of FIG. 9) and a display 110. For example, the electronic device 100 may further include an illuminance sensor 240 (e.g., a sensor module 976 of FIG. 9).

For example, the processor 210 may be operably or operatively coupled with the display 110 or the display driver circuit 220 in the display 110. For example, the processor 210 being operably or operatively coupled with the display 110 (or the display driver circuit 220) may indicate that the processor 210 is directly connected to the display 110 (or the display driver circuit 220). For example, the processor 210 being operatively coupled to the display 110 (or the display driver circuit 220) may indicate that the processor 210 is connected to the display 110 (or the display driver circuit 220) through another component of the electronic device 100. For example, the processor 210 being operably or operatively coupled with the display 110 (or the display driver circuit 220) may indicate that the state of the processor 210 is in a state capable of controlling the display 110 (or the display driver circuit 220). For example, the fact that the processor 210 being operably or operatively coupled with the display 110 (or the display driver circuit 220) may indicate that the operation of the display 110 (or the display driver circuit 220) is caused to perform based on information, data, signals, or instructions obtained from the processor 210. However, the disclosure is not limited thereto.

For example, the processor 210 may be operably or operatively coupled with the illuminance sensor 240.

For example, the display 110 may include a display driver circuit 220 (e.g., a display driver IC 1030 of FIG. 10) and a display panel 230 (e.g., a display 1010 of FIG. 10). For example, the display driver circuit 220 may be operably or operatively coupled with the display panel 230.

For example, the illuminance sensor 240 may be used to obtain data on brightness around the electronic device 100. For example, the illuminance sensor 240 may be used to obtain data indicating an illuminance value around the electronic device 100. For example, the electronic device 100 may provide a first mode for automatically changing a brightness level of the display 110 depending on the illuminance value and a second mode for manually changing a brightness level of the display 110. For example, the first mode may indicate a mode in which an image is displayed through the display panel 230 at the brightness level corresponding to the illuminance value, without an explicit user input. For example, the second mode may indicate a mode in which the image is displayed through the display panel 230 at a brightness level of the display 110 indicated by an explicit user input. For example, the illuminance sensor 240 may be utilized while the first mode of the first mode and the second mode is provided or enabled. However, the disclosure is not limited thereto.

For example, the display driver circuit 220 may obtain information on an image from the processor 210. For example, the information may be provided from the processor 210 to display the image on the display panel 230. For example, the information may be provided from the processor 210 based on a refresh rate or a scan rate. However, the disclosure is not limited thereto.

For example, the display driver circuit 220 may identify an on pixel ratio (OPR) of the image. For example, the OPR may be used to identify a brightness range illustrated with reference to FIG. 1. For example, the OPR may represent an average OPR. As a non-limiting example, in case where OPR of a first frame (or a first frame data) is ‘a’, OPR of a second frame (or a second frame data) is ‘b’, and OPR of a third frame (or a third frame data) is ‘c’, the display driver circuit 220 may identify the OPR as (a+b+c)/3. For example, a period for identifying the OPR may be longer than a frame period. However, the disclosure is not limited thereto.

For example, the display driver circuit 220 may identify the brightness level of the display 110 within a first brightness range 160 based on the OPR. For example, the display driver circuit 220 may identify the brightness level of the display 110 within a second brightness range 165 based on the OPR. For example, the second reference brightness level 162, which is the maximum brightness level of the first brightness range 160, may be a fixed value (or level). For example, the third reference brightness level 163, which is the maximum brightness level of the second brightness range 160, may be adaptively changed depending on the OPR, as opposed to the second reference brightness level 162 which is the maximum brightness level of the first brightness range 160. For example, when the OPR is 30%, the third reference brightness level 163 may be a first value, and when the OPR is 70%, the third reference brightness level 163 may be a second value lower than the first value. However, the disclosure is not limited thereto. As a non-limiting example, the second reference brightness level 162, which is the maximum brightness level of the first brightness range 160, may be adaptively changed. For example, the second reference brightness level 162 may gradually increase. For example, the second reference brightness level 162 may gradually increase based on the brightness level of the display 110 exceeding a threshold value within the first brightness range 160.

For example, the display driver circuit 220 may identify the brightness range based on the OPR and display the image within the identified brightness range. The brightness range identified based on the OPR may be illustrated with reference to FIG. 3.

FIG. 3 shows an example of a brightness range changed depending on an on pixel ratio (OPR) of an image.

Referring to FIG. 3, based on identifying that the OPR of the image 300 is the maximum OPR, the display driver circuit 220 may identify the brightness range for displaying the image 300 as the first brightness range 160 from the first reference brightness level 161 to the second reference brightness level 162. For example, the display driver circuit 220 may display the image 300 through the display panel 230 within the first brightness range 160.

For example, the processor 210 may obtain data (e.g., a bar indicator 620 and/or a bar indicator 632 of FIG. 6) for displaying the bar indicator 360 indicating that the first brightness range 160 is applied. For example, the display driver circuit 220 may display the bar indicator 360 based on the data obtained from the processor 210. For example, the bar indicator 360 may be displayed in a user interface for a quick access panel (or a control center). For example, the bar indicator 360 may be displayed in a user interface for global settings. However, the disclosure is not limited thereto.

For example, based on identifying that the OPR of an image 310 is the first OPR lower than the maximum OPR, the display driver circuit 220 may identify the brightness range for displaying the image 310 as the second brightness range 165-1 from the first reference brightness level 161 to the third reference brightness level 163-1. For example, the display driver circuit 220 may display the image 310 through the display panel 230 within the second brightness range 165-1. For example, the image 310 may be displayed at a brightness level higher than that of the image 300. For example, the maximum brightness level for the image 300 may be the second reference brightness level 162. For example, since the OPR (e.g., the first OPR) of the image 310 is lower than the OPR (e.g., the maximum OPR) of the image 300, the maximum brightness level for the image 310 may be the third reference brightness level 163-1 higher than the second reference brightness level 162 which is the maximum brightness level for the image 300.

For example, the processor 210 may obtain data for displaying a bar indicator 370 (e.g., the bar indicator 620 and/or the bar indicator 632 of FIG. 6) indicating that the second brightness range 165-1 distinct from the first brightness range 160 is applied. For example, the display driver circuit 220 may display the bar indicator 370 based on the data obtained from the processor 210. For example, the bar indicator 370 may be displayed within a user interface for a quick access panel (or a control center). For example, the bar indicator 370 may be displayed within a user interface for global settings. However, the disclosure is not limited thereto.

For example, the expression of the bar indicator 370 may be different from that of the bar indicator 360 in order to indicate that the second brightness range 165-1 is applied. For example, the bar indicator 370 may be visually highlighted with respect to the bar indicator 360. For example, the length of the bar indicator 370 may be longer than the length of the bar indicator 360. For example, the color of the visual element 371 in the bar indicator 370 may be different from the color of the visual element 361 in the bar indicator 360. Although not illustrated in FIG. 3, the color of a portion of the visual element 371 corresponding to the range from the second reference brightness level 162 to the third reference brightness level 163-1 may be visually highlighted with respect to each of the color of another portion of the visual element 371 corresponding to at least a portion of the range from the first reference brightness level 161 to the second reference brightness level 162 and the color of the visual element 361. However, the disclosure is not limited thereto. For example, the color of the visual element 372 in the bar indicator 370 for indicating the brightness level may be different from the color of the visual element 362 in the bar indicator 360 for indicating the brightness level. However, the disclosure is not limited thereto.

For example, based on identifying that the OPR of an image 320 is the second OPR lower than the first OPR, the display driver circuit 220 may identify the brightness range for displaying the image 320 as the second brightness range 165-2 from the first reference brightness level 161 to the third reference brightness level 163-2. For example, the display driver circuit 220 may display the image 320 through the display panel 230 within the second brightness range 165-2. For example, the image 320 may be displayed at a brightness level higher than that of the image 310. For example, the maximum brightness level for the image 310 may be the third reference brightness level 163-1. For example, since the OPR (e.g., the second OPR) of the image 320 is lower than the OPR (e.g., the first OPR) of the image 310, the maximum brightness level for the image 320 may be the third reference brightness level 163-2 higher than the third reference brightness level 163-1 which is the maximum brightness level for the image 310.

For example, the processor 210 may obtain data for displaying a bar indicator 380 (e.g., the bar indicator 620 and/or the bar indicator 632 of FIG. 6) indicating that the second brightness range 165-2 distinct from the first brightness range 160 is applied. For example, the display driver circuit 220 may display the bar indicator 380 based on the data obtained from the processor 210. For example, the bar indicator 380 may be displayed within a user interface for a quick access panel (or a control center). For example, the bar indicator 380 may be displayed within a user interface for global setting. However, the disclosure is not limited thereto.

For example, the expression of the bar indicator 380 may be different from that of the bar indicator 360 in order to indicate that the second brightness range 165-2 is applied. For example, the bar indicator 380 may be visually highlighted with respect to the bar indicator 360. For example, the length of the bar indicator 380 may be longer than the length of the bar indicator 360. For example, the color of the visual element 381 in the bar indicator 380 may be different from the color of the visual element 361 in the bar indicator 360. Although not illustrated in FIG. 3, the color of a portion of the visual element 381 corresponding to the range from the second reference brightness level 162 to the third reference brightness level 163-2 may be visually highlighted with respect to each of the color of another portion of the visual element 381 corresponding to at least a portion of the range from the first reference brightness level 161 to the second reference brightness level 162 and the color of the visual element 361. However, the disclosure is not limited thereto. For example, the color of the visual element 382 in the bar indicator 380 for indicating the brightness level may be different from the color of the visual element 362 in the bar indicator 360 for indicating the brightness level. However, the disclosure is not limited thereto.

For example, the expression of the bar indicator 380 may be different from that of the bar indicator 370 in order to indicate that the second brightness range 165-2 is applied. For example, the bar indicator 380 may be visually highlighted with respect to the bar indicator 370. For example, the length of the bar indicator 380 may be longer than the length of the bar indicator 370. For example, the color of the visual element 381 in the bar indicator 380 may be different from the color of the visual element 371 in the bar indicator 370. Although not illustrated in FIG. 3, the color of a portion of the visual element 381 corresponding to the range from the third reference brightness level 163-1 to the third reference brightness level 163-2 may be visually highlighted with respect to the color of another portion of the visual element 381 corresponding to at least a portion of the range from the second reference brightness level 162 to the third reference brightness level 163-1. However, the disclosure is not limited thereto. For example, the color of the visual element 382 in the bar indicator 380 for indicating the brightness level may be different from the color of the visual element 372 in the bar indicator 370 for indicating the brightness level. However, the disclosure is not limited thereto.

For example, based on identifying that the OPR of an image 330 is the third OPR lower than the second OPR, the display driver circuit 220 may identify the brightness range for displaying the image 330 as the second brightness range 165-3 from the first reference brightness level 161 to the third reference brightness level 163-3. For example, the display driver circuit 220 may display the image 330 through the display panel 230 within the second brightness range 165-3. For example, the image 330 may be displayed at a brightness level higher than that of the image 320. For example, the maximum brightness level for the image 320 may be the third reference brightness level 163-2. For example, since the OPR (e.g., the third OPR) of the image 330 is lower than the OPR (e.g., the second OPR) of the image 320, the maximum brightness level for the image 330 may be the third reference brightness level 163-3 higher than the third reference brightness level 163-2 which is the maximum brightness level for the image 320.

For example, the processor 210 may obtain data for displaying a bar indicator 390 (e.g., the bar indicator 620 and/or the bar indicator 632 of FIG. 6) indicating that the second brightness range 165-3 distinct from the first brightness range 160 is applied. For example, the display driver circuit 220 may display the bar indicator 390 based on the data obtained from the processor 210. For example, the bar indicator 390 may be displayed within the user interface for a quick access panel (or a control center). For example, the bar indicator 390 may be displayed within the user interface for global settings. However, the disclosure is not limited thereto.

For example, the expression of the bar indicator 390 may be different from that of the bar indicator 360 in order to indicate that the second brightness range 165-3 is applied. For example, the bar indicator 390 may be visually highlighted with respect to the bar indicator 360. For example, the length of the bar indicator 390 may be longer than the length of the bar indicator 360. For example, the color of the visual element 391 in the bar indicator 390 may be different from the color of the visual element 361 in the bar indicator 360. Although not illustrated in FIG. 3, the color of a portion of the visual element 391 corresponding to the range from the second reference brightness level 162 to the third reference brightness level 163-3 may be visually highlighted with respect to each of the color of another portion of the visual element 391 corresponding to at least a portion of the range from the first reference brightness level 161 to the second reference brightness level 162 and the color of the visual element 361. However, the disclosure is not limited thereto. For example, the color of the visual element 392 in the bar indicator 390 for indicating the brightness level may be different from the color of the visual element 362 in the bar indicator 360 for indicating the brightness level. However, the disclosure is not limited thereto.

For example, the expression of the bar indicator 390 may be different from that of the bar indicator 370 in order to indicate that the second brightness range 165-3 is applied. For example, the bar indicator 390 may be visually highlighted with respect to the bar indicator 370. For example, the length of the bar indicator 390 may be longer than the length of the bar indicator 370. For example, the color of the visual element 391 in the bar indicator 390 may be different from the color of the visual element 371 in the bar indicator 370. Although not illustrated in FIG. 3, the color of a portion of the visual element 391 corresponding to the range from the third reference brightness level 163-1 to the third reference brightness level 163-3 may be visually highlighted with respect to the color of another portion of the visual element 381 corresponding to at least a portion of the range from the second reference brightness level 162 to the third reference brightness level 163-1. However, the disclosure is not limited thereto. For example, the color of the visual element 392 in the bar indicator 390 for indicating the brightness level may be different from the color of the visual element 372 in the bar indicator 370 for indicating the brightness level. However, the disclosure is not limited thereto.

For example, the expression of the bar indicator 390 may be different from that of the bar indicator 380 in order to indicate that the second brightness range 165-3 is applied. For example, the bar indicator 390 may be visually highlighted with respect to the bar indicator 380. For example, the length of the bar indicator 390 may be longer than the length of the bar indicator 380.

Although not illustrated in FIG. 3, the color of a portion of the visual element 391 corresponding to the range from the third reference brightness level 163-2 to the third reference brightness level 163-3 may be visually highlighted with respect to the color of another portion of the visual element 381 corresponding to at least a portion of the range from the second reference brightness level 162 to the third reference brightness level 163-2. However, the disclosure is not limited thereto.

For example, the color of the visual element 392 in the bar indicator 390 for indicating the brightness level may be different from the color of the visual element 382 in the bar indicator 380 for indicating the brightness level. However, the disclosure is not limited thereto.

For example, the display driver circuit 220 may store a plurality of reference ranges for the OPR of an image. For example, the plurality of reference ranges may include a first reference range from a first value to a second value higher than the first value, a second reference range from the second value to a third value higher than the second value, and a third reference range from the third value to a fourth value higher than the third value. For example, the plurality of reference ranges may be associated with a plurality of brightness ranges, respectively. For example, the display driver circuit 220 may identify a brightness range for displaying the image as a second brightness range 165-3 associated with the first reference range, based on the OPR within the first reference range. For example, the display driver circuit 220 may identify a brightness range for displaying the image as a second brightness range 165-2 associated with the second reference range, based on the OPR within the second reference range. For example, the display driver circuit 220 may identify a brightness range for displaying the image as a second brightness range 165-1 associated with the third reference range, based on the OPR within the third reference range. For example, the display driver circuit 220 may identify a brightness range for displaying the image as the first brightness range 160, based on the OPR outside the first reference range, the second reference range, and the third reference range. However, the disclosure is not limited thereto.

As described above, the display driver circuit 220 may adaptively adjust or change the brightness range depending on the OPR of the image. The electronic device 100 can enhance the quality of the image displayed through the display panel 230, owing to adaptively adjusting the brightness range using the display driver circuit 220.

Referring back to FIG. 1, the second brightness range 165 may further include a range 166 in addition to the first brightness range 160. For example, various methods may be executed in the electronic device 100 to provide a brightness level within the range 166.

For example, the display driver circuit 220 may store reference data for a plurality of display brightness values for providing the first brightness range 160. For example, the reference data may include display brightness values for each of a plurality of brightness levels within the first brightness range 160. For example, the display brightness values may correspond to greyscales, respectively. For example, the reference data may be represented as shown in Table 1 below.

In Table 1 above, a1 to a49 represent the plurality of display brightness values, respectively. In the Table 1, the seventh brightness level may correspond to the second reference brightness level 162.

The display driver circuit 220 may provide a brightness level within the range 166, using the reference data for providing the first brightness range 160 as shown in Table 1 above. For example, the display driver circuit 220 may obtain from the processor 210 a control command indicating a brightness level outside the first brightness range 160. For example, the control command may be obtained based on a second cycle longer than a first cycle in which the information on the image is obtained. However, the disclosure is not limited thereto. For example, the control command may indicate a brightness level that is higher than the second reference brightness level 162 and lower than or equal to the third reference brightness level 163. For example, the control command may indicate the second reference brightness level 162 (e.g., the seventh brightness level in the Table 1), which is the maximum brightness level of the first brightness range 160. For example, the display driver circuit 220 may recognize the second reference brightness level 162 indicated by the control command as providing the maximum brightness level corresponding to the OPR of the image to be displayed through the display panel 230. However, the disclosure is not limited thereto.

For example, in response to the control command, the display driver circuit 220 may identify a display brightness value indicating the brightness level, by performing extrapolation method using at least some of the plurality of display brightness values in the reference data. For example, the extrapolation method may be performed by Equation 1 as follows:

Display Brightness Value=ai+(aj−ai)×(Brightness Level−ith Brightness Level)/(jth Brightness Level−ith Brightness Level) <Equation 1>

wherein the display brightness value of the Equation 1 represents the display brightness value for the brightness level when the grayscale is ‘c’ (where ‘c’ is a natural number of 1 to 255), which is identified by the display driver circuit 220, ‘ai’ of the Equation 1 represents the display brightness value for the ith brightness level (e.g., a brightness level lower than or equal to the second reference brightness level) when the grayscale is ‘c’ amongst the plurality of brightness levels in the reference data, ‘aj’ of the Equation 1 represents the display brightness value for the jth brightness level (a brightness level higher than the first reference brightness and lower than or equal to the second reference brightness level) when the grayscale is ‘c’ amongst the plurality of brightness levels in the reference data, the brightness level of Equation 1 is the brightness level indicated by the control command, indicating a brightness level higher than the second reference brightness level 162 and lower than or equal to the third reference brightness level 163, and ‘r’ of the Equation 1 is an additional correction value, indicating a predetermined value.

For example, when ‘i’ is 6 and T is 7, the above Equation 1 may be expressed as Equation 2 as follows:

Display Brightness Value=a48+(a49−a48)×(Brightness Level−6th Brightness Level)/(7th Brightness Level−6th Brightness Level) <Equation 2>

For example, the display driver circuit 220 may display the image on the display panel 230 at the brightness level indicated by the control command, based on the identified brightness value.

For example, the display driver circuit 220 may identify a current to be applied to each of a plurality of pixels in the display panel 230, using the reference data, and may display an image at the brightness level, based on providing the identified current to each of the plurality of pixels. For example, in response to the control command, the display driver circuit 220 may identify data on a difference between the second reference brightness level 162, which is the maximum brightness level of the first brightness range 160, and the brightness level indicated by the control command, based on at least some of the plurality of display brightness values in the reference data. For example, the display driver circuit 220 may identify a current to be applied to each of the plurality of pixels, based on the data. For example, the current may be identified based on gamma correction. For example, the display driver circuit 220 may display the image at the brightness level, based on providing the identified current to each of the plurality of pixels.

For example, the display driver circuit 220 may modulate or modify the image obtained from the processor 210, using the reference data, and may display the modified image at the brightness level. For example, in response to the control command, the display driver circuit 220 may identify data on a difference between the second reference brightness level 162, which is the maximum brightness level of the first brightness range 160, and the brightness level indicated by the control command, based on at least some of the plurality of brightness values in the reference data. For example, the display driver circuit 220 may display the image at the brightness level through the display panel 230 by modulating or modifying the image based on the data. For example, the modulation (or the modification) of the image may be performed for the gamma correction.

The above examples illustrate an example in which the reference data includes a plurality of display brightness values for providing the first brightness range 160, but the reference data may include a plurality of display brightness values for providing the second brightness range 165. For example, the display driver circuit 220 may store the reference data including the plurality of display brightness values for providing the second brightness range 165. The reference data may be represented as shown in Table 2 as follows.

In the Table 2 above, ‘a1’ to ‘a49’ and ‘b1’ to ‘b14’ represent the plurality of display brightness values. In the Table 2, each of the eighth brightness level and the ninth brightness level may correspond to a brightness level between the second reference brightness level 162 and the third reference brightness level 163.

For example, the display driver circuit 220 may use the reference data represented as in the Table 2 to identify some of the plurality of display brightness values corresponding to the brightness level indicated by the control command, in response to the control command indicating the brightness level higher than the second reference brightness level 162 and lower than or equal to the third reference brightness level 163. For example, the display driver circuit 220 may display an image at the brightness level through the display panel 230, based on some of the plurality of display brightness values. For example, at least one display brightness value corresponding to a brightness level higher than the second reference brightness level 162 and lower than or equal to the third reference brightness level 163 amongst the plurality of display brightness values may be obtained by performing calibration (e.g., multi-time programmable (MTP) calibration) using an image having an OPR lower than a reference OPR. For example, the brightness level higher than the second reference brightness level 162 and lower than or equal to the third reference brightness level 163 cannot be obtained while displaying a full white image as in the image 180 of FIG. 1, and therefore, the at least one display brightness value may be included in the reference data by performing the calibration using the image having the OPR lower than the reference OPR. The image having the OPR lower than the reference OPR may be illustrated with reference to FIG. 4.

FIG. 4 illustrates an example of an image having an OPR lower than a reference OPR.

Referring to FIG. 4, the electronic device 100 may include the at least one display brightness value in the reference data, by performing the calibration based on displaying an image having an OPR lower than the reference OPR, such as the image 410, the image 420, and/or the image 430. For example, the image 410 may include an area 411 in which some of the plurality of pixels in the display panel 230 are turned on (or enabled) and another area 412 in which the other ones (or the remaining ones) of the plurality of pixels in the display panel 230 are turned off (or disabled). For example, the image 420 may include an area 421 in which some of the plurality of pixels in the display panel 230 are turned on (or enabled) and an area 422 in which the other ones (or the remaining ones) of the plurality of pixels in the display panel 230 are turned off (or disabled). For example, the image 430 may include an area 431 in which some of the plurality of pixels in the display panel 230 are turned on (or enabled) and an area 432 in which the other ones (or remaining ones) of the plurality of pixels in the display panel 230 are turned off (or disabled). However, the disclosure is not limited thereto.

Referring back to FIG. 2, the display driver circuit 220 may display the image at a brightness level higher than the second reference brightness level 162 and lower than or equal to the third reference brightness level 163, based on changing the grayscale value of the image based on the OPR of the image obtained from the processor 210. For example, the grayscale value may be reduced according to the change. For example, a difference between the grayscale value and the reduced grayscale value may be identified based on the OPR. For example, under the condition that the OPR of the image is a first OPR, the display driver circuit 220 may obtain a first image in which the grayscale value of the image is reduced by a first value, and may display the first image at the brightness level through the display panel 230. For example, under the condition that the OPR of the image is a second OPR lower than the first OPR, the display driver circuit 220 may obtain a second image in which the grayscale value of the image is reduced by a second value smaller than the first value, and may display the second image at the brightness level through the display panel 230. For example, each of the first value and the second value may be identified further based on gamma correction. Reducing the grayscale value by the first value and reducing the grayscale value by the second value may be illustrated with reference to FIG. 5.

FIG. 5 illustrates an example of a method of adaptively changing a grayscale value of an image according to an OPR of the image.

Referring to FIG. 5, the display driver circuit 220 may identify the OPR of the image obtained from the processor 210 and adjust the grayscale value of the image based on the identified OPR. For example, the processor 210 may display the first image by reducing the grayscale value of the image by the first value, based on the image having the first OPR, and may display the second image by reducing the grayscale value of the image by the second value smaller than the first value, based on the image having the second OPR lower than the first OPR. For example, a chart (e.g., graph) 500 indicates a relationship between an input grayscale value and an output grayscale value when an OPR is the first OPR, and a chart (e.g., graph) 550 indicates a relationship between an input grayscale value and an output grayscale value when an OPR is the second OPR lower than the first OPR. For example, a horizontal axis of each of the chart 500 and the chart 550 represents the input grayscale value, and a vertical axis of each of the chart 500 and the chart 550 represents the output grayscale value. For example, the input grayscale value may represent the grayscale value of the image obtained from the processor 210, and the output grayscale value may represent the grayscale value of the image displayed or to be displayed through the display panel 230. For example, the input grayscale value may indicate the grayscale value of the image before the adjustment, and the output grayscale value may indicate the grayscale value of the image after the adjustment.

In the chart 500, when the OPR is the first OPR, the output grayscale value may be obtained by multiplying the input grayscale value by an inclination ‘a’ (wherein ‘a’ is a real number greater than 0 and less than 1). For example, when the input grayscale value is ‘255’, the output grayscale value may be ‘255a’. For example, a difference 510 between the input grayscale value and the output grayscale value may be ‘225-255a’.

In the chart 550, when the OPR is the second OPR lower than the first OPR, the output grayscale value may be obtained by multiplying the input grayscale value by an inclination ‘b’ (wherein ‘b’ is a real number greater than 0 and less than 1). For example, since the second OPR is lower than the first OPR, the inclination ‘b’ may be greater than the inclination ‘a’. For example, when the input grayscale value is ‘255’, the output grayscale value may be ‘255b’, which is greater than ‘255a’. For example, a difference 560 between the input grayscale value and the output grayscale value may be ‘255-255b’ which is less than the difference 510.

Each of the chart 500 and the chart 550 illustrates that the relationship between the input grayscale value and the output grayscale value is of a linear relationship, but it is only for convenience of description. The relationship may be of a non-linear relationship. For example, each of the chart 500 and the chart 550 is to represent that the difference between the input grayscale value and the output grayscale value corresponds to the OPR. For example, as the OPR of the image goes lower, the difference may decrease. However, the disclosure is not limited thereto.

Referring back to FIG. 2, the display driver circuit 220 may provide the brightness level within the range 166 by combining at least some of the above-described examples.

For example, the second brightness range 165 may be enabled or disabled based on a preset (e.g., specified) condition (e.g., a predetermined condition). For example, the set condition may include a condition that the remaining level of the rechargeable battery in the electronic device 100 is greater than or equal to a reference level. For example, the second brightness range 165 may be enabled under a condition that the remaining level is greater than or equal to the reference level, or may be disabled under a condition that the remaining level is less than the reference level. For example, the set condition may include a condition that an illuminance value around the electronic device 100 is greater than or equal to a threshold value. For example, the second brightness range 165 may be enabled under a condition that the illuminance value is equal to or greater than the threshold value, or may be disabled under a condition that the illuminance value is less than the threshold value. For example, the second brightness range 165 may be enabled under a condition that the illuminance value less than the threshold value is changed to be greater than or equal to the threshold value. For example, a first time interval in which the brightness level is increased within a portion of the second brightness range 165 between the second reference brightness level 162 and the third reference brightness level 163 may be longer than a second time interval in which the illuminance value is changed from a first value less than the threshold value to a second value greater than or equal to the threshold value. For example, the adjustment of the brightness level may be gradually performed within the portion of the second brightness range 165. However, the disclosure is not limited thereto.

For example, the set condition may be to receive a user input through a user interface displayed through the display panel 230. For example, the second brightness range 165 may be enabled based on the user input. The user interface and the user input may be illustrated in greater detail below with reference to FIG. 6.

FIG. 6 illustrates an example of a user interface for activating the second brightness range.

Referring to FIG. 6, as in a state 600, a bar indicator 620 for adjusting a brightness level may be displayed on the display panel 230. For example, the bar indicator 620 may be displayed within a quick panel 610. However, the disclosure is not limited thereto. For example, the bar indicator 620 may include a visual gauge element 622 for adjusting the brightness level within the brightness range and an executable object 621 for setting related to the brightness level. For example, the state 600 may be changed to a state 630 in response to a user input 623 to the executable object 621.

As in a state 630, a setting window 631 displayed in response to the user input 623 may include an executable object 634 for activating the second brightness range 165. For example, the setting window 631 may further include an executable object 633 for activating adaptive adjustment of the brightness level, based on the illuminance value (e.g., an illuminance value obtained through the illuminance sensor 240) around the electronic device 100, and a bar indicator 632 corresponding to the bar indicator 620. For example, the executable object 634 in the state 630 may indicate that the second brightness range 165 is disabled.

For example, the state 630 may be changed to a state 660 in response to a user input 635 to the executable object 634.

As in the state 660, the setting window 631 displayed in response to the user input 635 may include an executable object 634 indicating that the second brightness range 165 is enabled. For example, based on the executable object 634 activating the second brightness range 165 based on the user input 635, the executable object 634 may be displayed on the display panel 230, as in the state 660. For example, in the state 660, the executable object 633 and the bar indicator 632 may be maintained within the setting window 631. However, the disclosure is not limited thereto.

Referring back to FIG. 2, since the electronic device 100 is configured to adaptively adjusts the brightness range based on the OPR of the image, the electronic device 100 may change the brightness range according to the change in the OPR of the image. For example, the change in the brightness range may be gradually executed. However, the disclosure is not limited thereto.

For example, the display driver circuit 220 may display a first image through the display panel 230 at a first brightness level. For example, while the first image is displayed at the first brightness level, the display driver circuit 220 may obtain, from the processor 210, information about a second image having an OPR lower than that an OPR of the first image. For example, the display driver circuit 220 may display the second image changed from the first image at a second brightness level higher than the first brightness level, through the display panel 230, based on the obtaining. For example, the first image and the second image may be displayed while the illuminance value around the electronic device 100 is equal to or greater than a threshold value (or while the illuminance around the electronic device 100 is equal to or greater than a threshold illuminance). For example, the illuminance value being greater than or equal to the threshold value may indicate that it is appropriate to provide the maximum brightness level that can be provided through the display panel 230. The change in brightness level according to the change in the OPR may be illustrated with reference to FIG. 7.

FIG. 7 illustrates an example of changing a brightness level based on changing a first image having a first OPR to a second image having a second OPR.

Referring to FIG. 7, the display driver circuit 220 may display the image 180 at the first brightness level through the display panel 230, as in a state 700. For example, on condition that the illuminance value around the electronic device 100 is equal to or greater than the threshold value, adaptively adjusting the brightness level based on the illuminance value is enabled as indicated by the executable object 633 of FIG. 6, and the image 180 is of a full white image, the first brightness level may be a second reference brightness level 162 which is the maximum brightness level within the first brightness range 160.

The display driver circuit 220 may obtain, from the processor 210, information about the image 190 having an OPR lower than the OPR of the image 180, while the image 180 is displayed at the first brightness level. For example, the image 190 may be an image following the image 180. For example, the state 700 may be changed to a state 750 based on the obtaining.

For example, as in the state 750, the display driver circuit 220 may display the image 190 changed from the image 180 through the display panel 230 at a second brightness level higher than the first brightness level, based on the obtaining. For example, on condition that the illuminance value is maintained no less than the threshold value, adaptively adjusting of the brightness level based on the illuminance value is enabled, and the image 190 has an OPR lower than the OPR of the image 180, the second brightness level may be a third reference brightness level 163, which is the maximum brightness level within the second brightness range 165.

As described above, the electronic device 100 can identify the OPR of the image and adaptively identify the brightness level based on the identified OPR, thereby enhancing the quality of the service provided by displaying the image through the display panel 230. For example, the display driver circuit 220 may include a component for identifying an OPR, a component for performing gamma correction for providing a brightness level, and a component for providing current (or voltage) to pixels in the display panel 230 for the brightness level. The above components may be illustrated with reference to FIG. 8.

FIG. 8 illustrates an example of components of a display driver circuit in an exemplary electronic device.

Referring to FIG. 8, the display driver circuit 220 may include an OPR identification module (e.g. including OPR identification circuitry and/or executable program instructions) 810, a gamma correction module (e.g., including gamma correction circuitry and/or executable program instructions) 820, and a decoder 830.

For example, the OPR identification module 810 may include various circuitry used to identify an OPR of an image obtained from the processor 210. For example, the OPR identification module 810 may identify the OPR by obtaining data on the OPR of the image from the processor 210 or analyzing the image obtained from the processor 210. For example, the OPR identified by the OPR identification module 810 may be provided to the gamma correction module 820.

For example, the gamma correction module 820 may include various circuitry, including, for example, and without limitation, a gamma voltage generation module (e.g., including gamma voltage generation circuitry and/or executable program instructions) 821 and/or an image modulation module (e.g., including various image modulation circuitry and/or executable program instructions) 822.

For example, the gamma voltage generation module 821 may obtain a plurality of gamma voltages based on at least some of preset (or predetermined) gamma curves and provide the plurality of gamma voltages. For example, the gamma voltage generation module 821 may change at least some of the gamma curves by changing the maximum gamma voltage and/or the minimum gamma voltage. For example, the gamma voltage generation module 821 may provide information on the plurality of gamma voltages to the decoder 830, based on the OPR obtained from the OPR identification module 821 or an offset (or the difference) identified based on the OPR.

For example, the image modulation module 822 may modulate or modify the image obtained from the processor 210, based on the OPR obtained from the OPR identification module 810 or an offset (or the difference) identified based on the OPR. For example, the image modulation module 822 may provide information on the modulated or modified image to the decoder 830.

For example, the decoder 830 may generate image signals, based at least in part on the information obtained from the gamma voltage generation module 821 and/or the information obtained from the image modulation module 822. For example, the image signals may be obtained from converting the information obtained from the gamma voltage generation module 821 and/or the information obtained from the image modulation module 822. Although not illustrated in FIG. 8, the image signals obtained through the decoder 830 may be output from the display panel 230 via a plurality of amplifiers. However, the disclosure is not limited thereto.

At least some of the operations of the display driver circuit 220 described above may be executed by other components of the electronic device 100. For example, the at least some of the operations of the display driver circuit 220 may be executed by the processor 210.

FIG. 9 is a block diagram of an electronic device in a network environment according to an example of the disclosure. Referring to FIG. 9, an electronic device 901 in a network environment 900 may communicate with an electronic device 902 via a first network 998 (e.g., a short-range wireless communication network), or at least one of an electronic device 904 or a server 908 via a second network 999 (e.g., a long-range wireless communication network). According to an example, the electronic device 901 may communicate with the electronic device 904 via the server 908. According to an example, the electronic device 901 may include a processor 920, a memory 930, an input module 950, a sound output module 955, a display module 960, an audio module 970, a sensor module 976, an interface 977, a connecting terminal 978, a haptic module 979, a camera module 980, a power management module 988, a battery 989, a communication module 990, a subscriber identification module (SIM) 996, or an antenna module 997. In some embodiments, at least one of the components (e.g., the connecting terminal 978) may be omitted from the electronic device 901, or one or more other components may be added in the electronic device 901. In some embodiments, some of the components (e.g., the sensor module 976, the camera module 980, or the antenna module 997) may be implemented as a single component (e.g., the display module 960).

The processor 920 may execute, for example, software (e.g., a program 940) to control at least one other component (e.g., a hardware or software component) of the electronic device 901 coupled with the processor 920, and may perform various data processing or computation. According to an example, as at least part of the data processing or computation, the processor 920 may store a command or data received from another component (e.g., the sensor module 976 or the communication module 990) in a volatile memory 932, process the command or the data stored in the volatile memory 932, and store resulting data in a non-volatile memory 934. According to an example, the processor 920 may include a main processor 921 (e.g., a central processing unit (CPU) or an application processor (AP)), or an auxiliary processor 923 (e.g., a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operable independently from, or in conjunction with, the main processor 921.
