    摘要: An electronic device includes a display panel, a display driver IC (DDI), a gate driver, a light-emission driver, and a processor. The display panel includes multiple data lines, multiple gate signal lines, and light-emission signal lines. The DDI drives the display panel. The gate driver applies gate scan signals to the multiple gate signal lines, based on control of the DDI. The light-emission driver applies light-emission signals to the multiple light-emission signal lines, based on control of the DDI. The processor controls the DDI. The processor controls a first scan speed of the gate scan signals to be different from a second scan speed of the light-emission signals.

    摘要: An electronic device and a method for providing information of a foreign substance adsorbed from the outside of a camera are provided. The electronic device includes a transparent member formed with a first medium, a light emitter disposed under the transparent member and configured to emit light, a camera disposed under the transparent member and configured to obtain an image of an external object, and a processor. The processor may be configured to obtain a first image of the external object by using a difference of light refracting angles between the first medium and the second medium formed at an outer part of the transparent member by using the camera while at least one part of the light emitted by the light emitter is transmitted through an inner part of a second medium, obtain a second image of the external object by using the camera, and provide foreign substance information of a third medium adsorbed on at least one part of an outer surface of the transparent member by using a color difference between at least one partial area of the first image and at least one partial area of the second image.
