For example, the output brightness is determined by the processor 320 using at least one sensor (e.g., sensor module 176 in FIGS. 1 and 2) of the display 360 while the display 360 is activated. It may be part of a real time operating state. For example, the output brightness may be the average brightness of the entire area of the display 360. As another example, the output brightness may be the brightness of a partial area of the display 360.

For example, the processor 320 may determine whether to perform an operation to identify output brightness based on a setting state regarding whether the light leak improvement function is operating. For example, when the setting state regarding whether the light leak improvement function is operating is identified as ON, the processor 320 may identify the output brightness of the display 360 based on a designated cycle. As another example, the processor 320 may stop or not perform the identification of the output brightness of the display 360 when the setting state regarding whether the light leak improvement function operates is identified as OFF.

For example, processor 320 may calculate an average value of the identified output brightness. As an example, the processor 320 may calculate the average value of the output brightness of the display 360 using the output brightness and period value of the display 360 identified during a designated period.

For example, processor 320 may identify whether the average value is less than or equal to a threshold. As an example, the threshold may be a predefined value or a setting value that can be changed by the user.

For example, when the average value is below the threshold, the processor 320 may increase the black level of the display 360. The black level may be defined as the brightness level of the part with the lowest output brightness (or the darkest part) among the areas being output on the display 360. For example, when the average value of the processor 320 is below the threshold, the output brightness is relatively low, so usability may be reduced due to light leakage. Accordingly, the processor 320 may determine that the output brightness of the display 360 should be increased to improve light leakage. To increase output brightness, the processor 320 may increase the black level of the display 360.

For example, the processor 320 may control the amount of increase in the black level using a plurality of weights. As an example, the processor 320 may identify the luminance of the display 360 based on a designated cycle and identify the illuminance of an adjacent area of the electronic device 301 using the sensor 396. As an example, luminance may be a setting value related to the intensity of brightness of the display 360 set by the processor 320. As another example, illuminance may be the amount of light or light flow value generated within an area spaced apart from the electronic device 301 by a specified distance.

For example, the processor 320 may calculate the first weight and the second weight based on the identified luminance and illuminance, respectively. The processor 320 may increase the black level using predefined tuning strength, first weight, and second weight. For example, the processor 320 may calculate the final tuning strength by multiplying the predefined tuning strength, the first weight, and the second weight, and increase the black level based on the calculated final tuning strength. As an example, the processor 320 may calculate the first weight to be proportional to the identified luminance. As another example, the processor 320 may calculate the second weight to be inversely proportional to the identified illuminance.

For example, if the average value exceeds the threshold, the processor 320 may maintain the current output state of the display 360. For example, when the average value of the processor 320 exceeds the threshold, the output brightness is relatively high, so there is a low possibility of light leakage being visible and a decrease in usability. Accordingly, the processor 320 may determine that a change in the black level to improve light leakage is not required.

In one embodiment, memory 330 may store instructions or data.

For example, the memory 330 may store one or more instructions that, when executed by the processor 320, allow the electronic device 301 to perform various operations.

For example, the memory 330 may store various information related to the operation of the electronic device 301 to control the display 360. As an example, memory 330 may store a threshold value associated with the brightness of display 360. For example, the threshold may be defined as a reference value at which the output brightness of the display 360 is determined to cause a light leakage problem. As another example, the memory 330 may store a predefined tuning strength. The predefined tuning intensity may be defined as a reference intensity for adjusting the black level to improve light leakage. For example, the threshold and predefined tuning strength may be values set when manufacturing the electronic device 301. For another example, the threshold and predefined tuning strength may be setting values that can be changed by the user. As another example, the threshold and predefined tuning strength may be setting values received from an external electronic device (eg, a server).

In one embodiment, the display 360 can output various contents. For example, display 360 may include multiple output areas. As an example, the display 360 may include a first output area and a second output area surrounded by the first output area. The processor 320 may adjust the black level for only at least some of the plurality of output areas. Descriptions related to adjusting the black level for some output areas of the display 360 may be described in detail later in the description of FIGS. 4 and 5.

In one embodiment, the sensor 396 may obtain various information associated with the electronic device 301. For example, sensor 396 may include a light sensor. The processor 320 may identify the illuminance of an adjacent area of the electronic device 301 using the sensor 396. The processor 320 may determine a tuning intensity for increasing the black level using the identified illuminance.

The plurality of output areas of the display 460 shown in FIG. 4 may be logically divided areas. For example, the first output area 461 may be referred to as a border area of the display 460, and the second output area 462 may be referred to as a central area of the display 460. A relatively large amount of light leakage may occur in the first output area 461.

For example, when the display 460 is activated, the electronic device may identify the first output brightness of the first output area 461 based on a specified period and calculate a first average value of the identified first output brightness. there is.

For example, the electronic device may identify whether the calculated first average value exceeds a threshold.

For example, when the first average value is below the threshold, the electronic device may increase the first black level of the first output area 461 and maintain the second black level of the second output area 462.

For example, when the calculated first average value exceeds the threshold, the electronic device may maintain the output state of the display 460.

According to one embodiment, the electronic device may adjust the black level for only a partial area of the display 460 based on whether a specified standard is satisfied.

For example, the electronic device may adjust the black level only for some areas of the display 460 based on the setting state of brightness identification for the light leak improvement function of the display 460. As an example, based on the setting state being identified as being defined to perform brightness identification only for a portion of the display 460, the first output brightness of the first output area 461 is identified and identified with the threshold. The black level for the first output area 461 can be adjusted by comparing the first output brightness.

The electronic device can efficiently control the output contrast ratio of the display 460 and provide a high-quality output screen by adjusting the black level for only some of the plurality of output areas of the display 460.
