For example, the sampling information may be history information about the display, and may include image data output through the display. The image data may include luminance data and/or color data corresponding to each pixel. The electronic device according to an embodiment may periodically update sampling information according to a specified period. For example, the electronic device may accumulate image data according to a specified period and store it in a memory (eg, the memory 1830 of FIG. 18 ).

In operation 430, the electronic device according to an embodiment may determine (or predict) the degree of deterioration of each of a plurality of pixels of the display based on the updated sampling information. For example, pixels of a display may include organic light emitting diodes (OLEDs), and the color reproducibility of the organic light emitting diodes may gradually deteriorate (eg, deteriorate pixels) as usage time increases. The degree of deterioration of the pixel may be determined (or predicted) based on the use time or brightness of one pixel. For example, the electronic device may determine, based on the image data, that the deterioration degree of the pixel increases as the cumulative emission time of the pixel increases. For another example, the electronic device according to an embodiment may determine the degree of deterioration of pixels in a specific area of the display based on the updated sampling information. For example, the larger the difference between the operation time of the first state (eg, the first state S1 of FIG. 3 ) and the operation time of the second state (eg, the second state S2 of FIG. 3 ) is, the greater the It may be determined that the degree of deterioration of pixels located in area 1 (eg, the first area A1 of FIG. 3 ) is large. According to an embodiment, the degree of degradation includes each sampling information (eg, sampling information of operation 510 of FIG. 5 and/or sampling information of operation 570 of FIG. 5 ) and a period in which each sampling information is acquired (eg, FIG. 5 ). may include an accumulated value based on the first period and/or the second period of .

Hereinafter, an operation in which the electronic device updates sampling information (operation 420 of FIG. 4 ) according to an embodiment will be described in detail with reference to FIG. 5 . 5 is a flowchart illustrating an operation configuration of an electronic device according to an exemplary embodiment.

In operation 510, the electronic device (eg, the electronic device 100 of FIG. 1 ) according to an embodiment may update sampling information repeatedly according to a first cycle. For example, the first period may be a preset initial value. As another example, the first period may be a period determined based on the first parameter information or the second parameter information. The electronic device may update sampling information by accumulating information acquired according to the first period, and may store the sampling information updated according to the first period in a memory (eg, the memory 1830 of FIG. 18 ).

In operation 520, the electronic device according to an embodiment may acquire usage pattern information. The usage pattern information may include information related to a first state (eg, a first state S1 of FIG. 3 ) and a second state (eg, a second state S2 of FIG. 3 ) of the electronic device. For example, the usage pattern information may include the accumulated operation time of the first state, the accumulated operation time of the second state, the difference between the accumulated operation time of the first state and the accumulated operation time of the second state, the number of operations of the first state, or the second state. It may include at least any one of the number of operations in the two states. For another example, the usage pattern information includes the accumulated output time of the first area of the display (eg, the first area A1 of FIG. 3 ), the second area of the display (eg, the second area A2 of FIG. 3 )) It may include at least one of the accumulated output time of , or the difference between the accumulated output time of the first area of the display and the accumulated output time of the second area of the display. The accumulated output time of the first area of the display may be calculated based on the accumulated operation time of the first state and the accumulated operation time of the second state, and the accumulated output time of the second area of the display is the accumulated operation time of the second state. can be calculated based on

In operation 530, the electronic device according to an embodiment may determine whether the usage pattern information satisfies a specified condition. For example, the electronic device may determine whether the accumulated output time of the first area of the display and the accumulated output time of the second area of the display are equal to or greater than a specified value. As another example, the electronic device may determine whether a difference between the accumulated operation time of the first state and the accumulated operation time of the second state is equal to or greater than a specified value. As another example, the electronic device may determine whether the number of operations in the first state or the number of operations in the second state is greater than or equal to a specified number.

If it is determined that the usage pattern information does not satisfy the specified condition, the electronic device may perform operation 510 .

If it is determined that the usage pattern information satisfies the specified condition, in operation 540, the electronic device compares the period based on the first parameter information with the period based on the second parameter information, and determines the period based on the first parameter information as the second parameter It can be determined whether the period is smaller than the information-based period.

The first parameter information may include at least a part of usage pattern information. For example, the first parameter information may include the accumulated operation time of the first state, the accumulated operation time of the second state, the difference between the accumulated operation time of the first state and the accumulated operation time of the second state, the number of operations of the first state, or It may include at least one of the number of operations in the second state. The electronic device may determine a period value based on usage pattern information (or first parameter information). For example, the period according to the first parameter information may be determined according to a difference value between the accumulated operation time of the first state and the accumulated operation time of the second state until the time point at which operation 540 is performed. As the difference between the accumulated operation time of the first state and the accumulated operation time of the second state increases, the period based on the first parameter information may be set longer.

When the user's usage ratio for any one of the first and second states is greater than or equal to a specified value, the user's usage pattern for the first or second state can be easily predicted, and the update cycle of the sampling information can be shortened. Even if it is long, it may be possible to determine the deterioration of the pixel. According to an embodiment, as the difference between the accumulated operation time of the first state and the accumulated operation time of the second state increases, the period based on the first parameter information may be set longer to minimize the update of the sampling information, and the sampling information may be minimized. Resources consumed for information update and current consumption can be reduced.

To determine the period based on the first parameter information, the electronic device may use first period information including update period values of sampling information corresponding to values of the first parameter information. For example, the first period information may include update period values of sampling information corresponding to difference values between the accumulated operation time of the first state and the accumulated operation time of the second state. The first period information may be stored in a memory of the electronic device (eg, the memory 1830 of FIG. 18 ) in the form of a lookup table (LUT).

The second parameter information may be information that can be used to determine whether the same or similar images are repeatedly output. For example, the second parameter information may include application usage time. The electronic device may determine a period value based on the second parameter information (or application usage time). For example, the period based on the second parameter information may be longer as the accumulated use time of a specific application increases until the time point at which operation 540 is performed. To determine the period based on the second parameter information, the electronic device may use second period information including update period values of sampling information corresponding to values of the second parameter information. For example, the second period information may include update period values of sampling information corresponding to application use time values. The second period information may be stored in a memory of the electronic device (eg, the memory 1830 of FIG. 18 ) in the form of a look-up table. When the user's usage time of the same application is equal to or greater than a specified value, image data output to the display may be easily predicted, and even if the update period of the sampling information is long, the degree of pixel deterioration may be determined.

If the period based on the first parameter information is smaller than the period based on the second parameter information, in operation 550, the electronic device according to an embodiment may set the period according to the first parameter information as the second period.

If the period according to the first parameter information is equal to or greater than the period according to the second parameter information, in operation 560, the electronic device according to an embodiment may set the period according to the second parameter information as the second period.

In operation 570, the electronic device according to an embodiment may update sampling information according to a set second period. The second period may have a value different from that of the first period, and may be longer than the first period. The electronic device may update sampling information by accumulating information acquired according to the second period, and may store the sampling information updated according to the second period in a memory (eg, the memory 1830 of FIG. 18 ). The electronic device according to an embodiment may reduce an excessively long update period of the sampling information by setting a value having a smaller period among the period based on the first parameter information and the period based on the second parameter information as the second period. and a degree of degradation and an output compensation value may be determined.
