Electronic device and driving method of electronic device

An electronic device comprising:

• a display panel configured to display an image, and including a plurality of pixels connected with a plurality of data lines and a plurality of scan lines;
• a data driving circuit configured to drive the plurality of data lines;
• a scan driving circuit configured to drive the plurality of scan lines;
• and
• a driving controller configured to generate image data based on a received image signal and to control the data driving circuit and the scan driving circuit,
• wherein the driving controller is configured to determine a gray level of the image signal,
• wherein the driving controller is configured to determine a dither pattern of the image signal,
• wherein the driving controller is configured to determine a driving frequency of the image signal,
• wherein the driving controller is configured to determine whether the gray level is a predetermined value or less,
• wherein the driving controller is configured to determine whether dithering is applied to the image data when the gray level is the predetermined value or less,
• wherein the driving controller is configured to determine whether the display panel operates in a variable driving frequency mode when it is determined that the dithering is applied, and
• wherein the driving controller is configured to compensate for the image data based on the gray level, the dither pattern, and the driving frequency when it is determined that the display panel operates in the variable driving frequency mode.

A driving method of an electronic device, the method comprising:

• generating image data based on an image signal received for displaying an image in a display panel;
• determining a gray level of the image based on the image signal and whether the gray level is a predetermined value or less;
• determining a dither pattern of the image and whether dithering is applied to the image when the gray level is the predetermined value or less based on the image signal;
• determining a driving frequency of the image based on the image signal and, when it is determined that the dithering is applied, determining whether the driving frequency of the image signal is variable;
• and
• determining whether to compensate for the image data based on the gray level and at least one of the dither pattern and the driving frequency and compensating for the image data,
• wherein the compensating for the image data includes:
• when the gray level is the predetermined value or less, the dither pattern is applied to the image signal, and the display panel does not operate in a variable driving frequency, compensating for the image data only based on the gray level and the dither pattern.
