摘要： A display device include a lens, a light source, a display panel including normal pixels and sensor pixels numbering less than the normal pixels to display an image, a reflective member reflecting display light emitted from the display panel toward the lens, and a processor. The processor controls the light source to emit near-infrared light, receive the near-infrared light reflected by a user's eye, converts information input to the sensor pixels into image data, generates eye feature models similar to the image data using a learning algorithm, determines an eye feature model most similar to an eye area of the image data among the generated eye feature models, tracks movement of a pupil center based on the determined eye feature model, and displays the image in high-resolution in a central vision area and the image in low-resolution in a peripheral vision area, using spatial coordinates of the tracked pupil center.
