Display device and display driving method with grayscale compensation

An electronic device comprising:

• a display panel including pixels including first pixels having a first viewing angle and disposed in a first pixel row and second pixels having a second viewing angle and disposed in a second pixel row, a first display area where an image is displayed through first pixels, and a second display area where an image is displayed through second pixels;
• a gate driver that provides gate voltages to a first gate line connected to the first pixel row and a second gate line connected to the second pixel row;
• a data driver that provides data voltages to the pixels;
• and
• a driving controller that controls the gate driver and the data driver,
• wherein the driving controller compensates for a grayscale value of at least one first pixel among first pixels of the second display area, and
• wherein sub-pixels included in each of the second pixels are surrounded by a partition wall.

A method of driving a display device including a display panel including pixels including first pixels having a first viewing angle and disposed in a first pixel row and second pixels having a second viewing angle and disposed in a second pixel row, a first display area where an image is displayed through first pixels, and a second display area where an image is displayed through second pixels, comprising:

• determining mask values of a mask;
• performing a convolution operation on a grayscale value of any one first pixel among first pixels of the second display area and a grayscale value of at least one pixel among the pixels adjacent to the any one first pixel with the mask to generate a compensation grayscale value for the any one first pixel;
• and
• compensating for the grayscale value of the any one first pixel with the compensation grayscale value.
