Abstract: 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.

Abstract: Provided are VR image processing method and apparatus. The method includes: rendering left-eye and right-eye viewpoint regions based on left-eye and right-eye view angles respectively, to obtain left-eye and right-eye viewpoint images; determining a candidate region based on positions of the left-eye and right-eye view angles, and selecting a point in the candidate region as a peripheral image view angle; rendering left-eye and right-eye viewpoint peripheral regions based on the peripheral image view angle, to obtain a same viewpoint peripheral image; and splicing the viewpoint peripheral image with the left-eye viewpoint image and with the right-eye viewpoint image to obtain a left-eye complete image and a right-eye complete image.

Abstract: A woofer speaker is provided, comprising a woofer speaker unit, a first sealing pad, a second sealing pad and a housing. The first sealing pad is fixed closely with the outer edge of the housing; the woofer speaker unit is fixed and sealed within the housing by the first sealing pad, and the second sealing pad is located between the woofer speaker unit and the housing; a sound hole is provided on the housing, and the shape and size of the sound hole correspond to those of the woofer speaker; and the terminal installation plane is the rear cover of the woofer speaker, and together with the housing forms the rear sound cavity of the woofer speaker through the first sealing pad. The cavity of the woofer speaker provided by the invention and the installation terminal applying the woofer speaker resolve the rear cover vibration problem of ultra-thin woofer speakers.
