Description

BACKGROUND

Field

The disclosure relates to an electronic device including an in-display optical sensor.

Description of Related Art

Organic light-emitting displays applied to electronic devices do not require separate light sources and thus are advantageous to lightweightness and compactness, and are widely utilized due to the advantages of higher response rates than other displays and excellent light-emitting efficiency, luminance, or field of view. By utilizing organic light-emitting displays, the screen display area on the front side of electronic devices are increasing, and optical sensors conventionally disposed on the front side of electronic devices are disposed on the periphery or back side of the display to be adjacent to the display.

When an under display camera (UDC) is applied to an electronic device, multiple pixels and a driving circuitry may be partially removed from the display area corresponding to disposition of the UDC so as to secure a light-transmitting area for the UDC. In this case, the pixel density of the display area corresponding to disposition of the UDC is smaller than the pixel density of other display areas, and the resolution of the display area corresponding to disposition of the UDC may thus be degraded.

Therefore, when data is output through the display, the visibility of the display area corresponding to disposition of the UDC may become noticeable according to the luminance value or gradation value of the data, thereby degrading the immersive experience of the user who watches the screen of the electronic device.

SUMMARY

An electronic device according to various example embodiments of the disclosure may include: a camera sensor, a display panel including a first area corresponding to an area in which the camera sensor is disposed, and a second area different from the first area, and a display driver IC (DDI) configured to drive the display panel, wherein the DDI is configured to: obtain at least one of a luminance value or a gradation value of a first image output to the first area, determine whether to control the first image output to the first area based on at least one of the luminance value or the gradation value of the first image, and control the first image output to the first area in response to the determination, wherein the first image is controlled such that, based on at least one of the luminance value of the first image or the gradation value of the first image, a plurality of pixels disposed in the first area are powered off, or a third image different from the first image is output to the first area.

A method of controlling an electronic device including a display panel including a first area corresponding to an area in which a camera sensor is disposed and a second area different from the first area according to various example embodiments of the disclosure may include: obtaining at least one of a luminance value of a first image output to the first area or a gradation value of the first image, determining whether to control the first image output to the first area based on at least one of the luminance value of the first image or the gradation value of the first image, and controlling the first image output to the first area in response to the determination, wherein the first image is controlled such that, based on at least one of the luminance value of the first image or the gradation value of the first image, a plurality of pixels disposed in the first area are powered off, or a third image different from the first image is output to the first area.

An electronic device according to various example embodiments of the disclosure may include: a camera sensor, a display panel including a first area corresponding to an area in which the camera sensor is disposed, and a second area different from the first area, a display driver IC (DDI) configured to drive the display panel, and a processor electrically connected to the camera sensor, the display panel, and the display driver IC, wherein the processor is configured to: obtain at least one of a luminance value of a first image output to the first area and a gradation value of the first image through the DDI, determine whether to control the first image output to the first area based on at least one of the luminance value of the first image and the gradation value of the first image, and control the first image output to the first area through the DDI in response to the determination, wherein the first image is controlled such that, based on at least one of the luminance value of the first image or the gradation value of the first image, a plurality of pixels disposed in the first area are powered off, or a third image different from the first image is output to the first area.

In an embodiment, the display driver IC 140 may output the first image through the first area 1211, when the luminance value of the first image output to the first area 1211 is less than the maximum brightness level controllable by a user input.

Various embodiments as set forth herein may be implemented as software (e.g., the program 1040) including one or more instructions that are stored in a storage medium (e.g., internal memory 1036 or external memory 1038) that is readable by a machine (e.g., the electronic device 1001). For example, a processor (e.g., the processor 1020) of the machine (e.g., the electronic device 1001) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the “non-transitory” storage medium is a tangible device, and may not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
