Display device and method for driving the same

A method for driving a display device, the display device including a transparent layer disposed to correspond to a display area of a lens, a light source emitting near-infrared light, a display panel including normal pixels to display an image and sensor pixels including photodiodes, a number of sensor pixels being smaller than the number of the normal pixels, and a reflective member reflecting display light emitted from the display panel toward the transparent layer, the method comprising:

• controlling the light source to emit the near-infrared light;
• receiving information from the sensor pixels based on the near-infrared light reflected by an eye of a user;
• converting the information received from the sensor pixels into image data;
• generating eye feature models representing an eye area of the eye from the image data using a learning algorithm;
• determining an eye feature model among the generated eye feature models most similar to an eye area of the image data;
• tracking movement of a pupil center of the eye based on the determined eye feature model to determine spatial coordinates of the tracked pupil center;
• and
• displaying a first part of the image in high-resolution in a central vision area corresponding to a direction of a sight line of the user and displaying a second part of the image in low-resolution in a peripheral vision area excluding the central vision area, using the spatial coordinates.
