摘要： A near-eye display device and an eye tracking system for the near-eye display device are provided. The eye tracking system includes a processor, a control analysis device, an LED illuminating device, a DMD display device and an IR camera. The processor outputs a video signal corresponding to a video displayed on the near-eye display device to the control analysis device. The control analysis device generates an LED synchronization signal and a corresponding subfield display signal. The LED illuminating device drives an LED to emit light, and transmits the light emitted from the LED into the DMD display device. The DMD display device reflects the light into a lens to form an image, and projects the image onto an eye. The IR camera captures an eye image. The control analysis device acquires the eye image and analyzes the eye image to obtain gaze point information.
