1 is a block diagram of an electronic device according to one embodiment.

In the outdoor environment, when external light such as the sun is reflected on the display 170, interference may occur due to the reflected light, so that the contents output to the display 170 may not be visible. Accordingly, the electronic device 100 can improve the visibility of the content output to the display 170 by increasing the luminance of the display 170 when the luminance value is equal to or greater than the designated size (for example, 40,000 lux) have. However, since the current consumed by the display 170 also increases as the brightness of the display 170 increases, the power consumed by the display 170 is increased to supply power to the components of the electronic device 100 The consumption of the battery can also be increased.

In order to reduce the power consumed by the display 170 in a situation where the brightness of the display 170 needs to be increased, such as in an outdoor environment, the electronic device 100 may consume less power than the sub- The power consumed by the display 170 can be lowered without lowering the overall luminance of the display 170 by lowering the power consumption in the current-rich subpixel.

The electronic device 100 for performing the functions described above may include a processor 110, a memory 130, a sensor 150, and a display 170, with reference to FIG. However, the configuration of the electronic device 100 is not limited thereto. According to various embodiments, electronic device 100 may omit at least one of the components described above, and may further include at least one other component.

The processor 110 may perform operations and data processing relating to control and / or communication of at least one other component of the electronic device 100. [ Processor 110 may load or process instructions or data received from at least one of the other components (e.g., inactive memory) into volatile memory and store the various data in non-volatile memory . Processor 110 may load a program (or instruction set) and data associated with control of display 170 into memory 130 and process it according to a designated program routine.

According to one embodiment, the processor 110 may change the gamma setting value delivered to the display 170 if the measured illumination value based on the sensor 150 is greater than or equal to the specified magnitude. For example, the processor 110 may change the gamma setting value for at least one of the gamma setting values (e.g., red pixel, green pixel, or blue pixel). In this regard, the gamma setting value may include data defining a gamma voltage reflecting the gamma characteristic of the display 170 for each gradation of the image data. In addition, each data voltage applied to the sub-pixels of the display 170 may be generated based on the gamma voltage defined for each gray-scale. That is, the gradation voltage corresponding to the gradation value of the image data to be outputted to the display 170 is output as the data voltage, and the gradation voltage can be generated based on the gamma voltage.

According to one embodiment, the processor 110 may change the gamma setting value for a sub-pixel (e.g., a blue pixel) having a high consumption current despite the low luminance among the sub-pixels of the display 170 to be smaller than a predetermined value have. For example, the processor 110 may change the gamma setting value for the subpixel of the display 170 to a predetermined value or less and the consumption current for the subpixel of the specified size or larger to a value smaller than a predetermined value. When the gamma setting value is set to a small value, the corresponding gamma voltage is changed to be high, so that the data voltage applied to the subpixel is outputted at a high level. As a result, the driving voltage applied to the light emitting device The voltage consumed by the sub-pixel may be lowered.

Although a blue pixel is exemplified as a sub pixel having a high consumption current despite the low luminance among the sub pixels of the display 170, the present invention is not limited thereto. However, in the case of a blue pixel, the amount of energy required may be large because a band gap for emitting light is relatively larger than a red pixel and a green pixel. Accordingly, the blue pixel may consume a large amount of current even though the luminance is lower than that of the red pixel and the green pixel.

According to one embodiment, the processor 110 may change the image data delivered to the display 170 if the measured illumination value based on the sensor 150 is greater than or equal to the specified magnitude. For example, the processor 110 may change the tone value to be output to each subpixel of the display 170. In this regard, the image data may be converted to analog data, i. E., The data voltage, and delivered to each subpixel of display 170.

According to one embodiment, the processor 110 may change the tone value for at least one color (e.g., blue color) of the image data to a smaller value. When the gray level value is changed to a small value, the data voltage corresponding to the gray level value is converted high, so that the power consumed by the subpixel can be lowered.

According to one embodiment, in order to prevent a reduction in the overall luminance of the display 170 that may occur by setting a low gamma setting for any one subpixel of the display 170, The gamma setting value for the other subpixels of the display unit 170 may be set high. For example, the processor 110 may set the gamma setting value for at least one of the red pixel and the green pixel to be higher than a predetermined value, while setting the gamma setting value for the blue pixel to be lower than a predetermined value.

According to one embodiment, in order to prevent a decrease in the overall luminance of the display 170, which may be caused by a small change in the tone value for any one color of the image data, Can be adjusted. For example, the processor 110 may change the tone value for at least one of the red color and the green color to a large value while changing the tone value for the blue color in the image data to a small value. In this case, the processor 110 may apply the same or a similar rate of change of the tone value for each color.

The memory 130 may store instructions or data related to at least one other component of the electronic device 100. For example, the memory 130 may store software and / or programs. According to one embodiment, the memory 130 may store a program (or set of instructions) associated with control of the display 170. The program (or set of instructions) associated with the control of display 170 may include, for example, instructions to measure illumination based on sensor 150, a gamma setting A command to change the value or an instruction to change the image data transferred to the display 170 when the measured illuminance value is equal to or larger than the specified magnitude. As another example, the memory 130 may store data related to the control of the display 170. The memory 130 may store data defining the gamma voltage reflecting the gamma characteristic of the display 170 for each gradation of the image data, that is, the gamma setting value. According to one embodiment, the memory 130 may store the gamma setting values in the form of a lookup table.

The sensor 150 may measure a physical quantity or sense an operating state of the electronic device 100 and convert the measured or sensed information into an electrical signal. The sensor 150 may, for example, include an illuminance sensor capable of measuring ambient illuminance.
