According to various embodiments of the present invention, the processor 430 may be, for example, a power management system (PMS) of FIG. The processor 430 may calculate the illuminance brightness value (platform code) between the illuminance sensor 410 and the driver 450.

The display panel 490 may be a display device such as a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, or a microelectromechanical systems (MEMS) paper display, and the like. Further, the display panel 490 may have a flat shape, or may have a shape having at least some curved surfaces.

Hereinafter, the operation of the processor 430 will be described in more detail.

The processor 430 may obtain the ambient brightness information using the ambient light sensor 410. [ The obtained peripheral brightness information is referred to as first peripheral brightness information. The processor 430 may select one basic brightness information corresponding to the current surrounding brightness among the plurality of surrounding brightness information stored in the memory based at least on the first surrounding brightness information.

The processor 430 may calculate a first brightness offset value corresponding to the first peripheral brightness information when the peripheral brightness information is the first peripheral brightness information and a second brightness offset value corresponding to the second peripheral brightness information when the peripheral brightness information is the second peripheral brightness information The second brightness offset value corresponding to the surrounding brightness information can be determined. The first brightness offset value may be a value corresponding to a brightness level selected through the brightness control bar UI in the first surrounding brightness information. For example, the first brightness offset value may be a difference between a brightness corresponding to the brightness level selected through the brightness control bar UI and a basic brightness selected based at least on the first surrounding brightness information.

The processor 430 may determine the first output brightness information or the second output brightness information by considering the corresponding offset value and the selected basic brightness information among the first brightness offset value and the second brightness offset value.

The processor 430 may adjust the brightness of the display panel 490 using the determined output brightness information.

According to various embodiments of the present invention, the processor 430 may generate illuminance output brightness information including the first output brightness information and the second output brightness information. The processor 430 may adjust the brightness of the display panel 490 based on the output brightness information by the illuminance. At this time, the processor 430 may display the corresponding output brightness value on the display panel 490 based on the illuminance input through the illuminance sensor 410, without the user's brightness adjustment request through the user input, .

According to various embodiments of the present invention, if the second ambient brightness information is higher than the first ambient brightness information, the second output brightness information may have a higher value than the first output brightness information. For example, it is assumed that the third brightness offset is obtained through the user input circuit in the third ambient brightness information that is higher than the second ambient brightness information. The processor 430 may determine the third output brightness information value using the third ambient brightness information and the third brightness offset. If the determined third output brightness information value is lower than the second output brightness information value, the processor 430 may modify the third output brightness information to a value equal to or greater than the second output brightness information.

For example, it is assumed that the fourth brightness offset is obtained through the user input circuit in the fourth surrounding brightness information. The processor 430 may determine the fourth output brightness information value using the fourth surrounding brightness information and the fourth brightness offset. If the first ambient brightness information value has a value within a predetermined range from the fourth ambient brightness information value, the first output brightness information may be deleted. For example, the preset range is assumed to be 1 / 2.5 to 2.5 times. If the first ambient brightness information is 100 lux and the newly input fourth ambient brightness information is 300 lux, the processor 430 may maintain the first output brightness information and store the fourth output brightness information . On the other hand, when the second ambient brightness information is 200 lux, the processor 430 may delete the second output brightness information and store the fourth output brightness information. If the first ambient brightness information is 100 lux, the second ambient brightness information is 200 lux, and the fourth ambient brightness information is 150 lux, the processor 430 outputs the first output brightness information and the second output brightness information, 2 output brightness information and store the fourth output brightness information. In this way, the processor 430 can reduce the complexity of the output brightness information to be reflected on the display panel 490 from time to time as the illuminance changes by deleting a plurality of offset information for each of the adjacent ambient brightness information.

According to various exemplary embodiments of the present invention, when the processor 430 receives a brightness value greater than a predetermined brightness value through the brightness sensor 410 and receives a brightness value less than a preset brightness value through the user input circuit 420, The brightness value corresponding to the brightness value and the brightness offset value may not be applied to the display panel 490. For example, when a too low offset value is input in the bright light of the outdoor, the user can prevent the display panel 490 from seeing anything, which can be prevented. In this case, the processor 430 may provide notification through the display panel 490 that the corresponding brightness level can not be selected in the brightness control bar UI.

However, for example, if the ambient illuminance value is 100 and the user has lowered the second brightness level 515 to the first brightness level 513 through the brightness adjustment bar UI 510, And may be a value when the ambient illuminance value is 100 in the illuminance level graph 523. In this case, since the output brightness value is lower than the basic brightness value, the brightness offset may have a negative value (negative value). If the ambient illuminance value is 1000 and the user has lowered the second brightness level 515 to the third brightness level 517 through the brightness adjustment bar UI 510, And may be a value when the ambient illuminance value is 100 in the graph 523. In this case, since the output brightness value is higher than the basic brightness value, the brightness offset may have a positive value (positive value).
