Display device and electronic device including the display device

A display device comprising:

• a display panel including a plurality of pixels;
• a driving controller configured to generate output image data based on input image data;
• and
• a data driver configured to generate a data voltage based on the output image data,
• wherein the driving controller includes:
• a driving frequency determiner configured to determine a driving frequency of the display panel;
• a low grayscale range determiner configured to determine a first reference grayscale based on the driving frequency, determine a second reference grayscale based on the driving frequency, and determine a low grayscale range in which a minimum grayscale is the first reference grayscale and a maximum grayscale is the second reference grayscale;
• and
• an output ratio determiner configured to determine an output ratio and an output order of first reference output image data corresponding to the first reference grayscale and second reference output image data corresponding to the second reference grayscale.

An electronic device comprising:

• a processor configured to output input image data;
• a memory device configured to store data required for an operation of the processor;
• a display panel including a plurality of pixels;
• a driving controller configured to generate output image data based on the input image data;
• and
• a data driver configured to generate a data voltage based on the output image data,
• wherein the driving controller is configured to:
• determine a low grayscale range in which a minimum grayscale is a first reference grayscale and a maximum grayscale is a second reference grayscale based on a driving frequency;
• and
• determine an output ratio and an output order of first reference output image data corresponding to the first reference grayscale and second reference output image data corresponding to the second reference grayscale.
