摘要： A near-eye display apparatus is configured to be disposed in front of at least one eye of a user and includes an illumination system, a display device, and a micro-lens array. The illumination system is configured to provide an illumination beam including sub-illumination beams. The display device is located on a transmission path of the illumination beam. The sub-illumination beams form corresponding sub-illumination regions on the display device, and the display device is configured to convert the sub-illumination beams irradiating the display device and corresponding to the sub-illumination regions into sub-image beams. An exit angle of each sub-image beam emitted from the display device is less than or equal to 20 degrees. The near-eye display apparatus provided herein is capable of eliminating stray light and characterized by good quality.

摘要： An HMD apparatus includes an image source, a light guiding element, a first modulating element, and a second modulating element. The image source provides an image beam. The light guiding element is arranged on a transmission path of the image beam to transmit the image beam. The light guiding element has a first surface and a second surface opposite to each other. The image beam undergoes total internal reflection at the first surface and is emitted from the second surface. The first modulating element is arranged on one side of the first surface of the light guiding element and configured to adjust a transmittance of an ambient beam. The light guiding element is arranged between the first and second modulating elements, and the second modulating element is configured to adjust a focus position of the image beam. The HMD apparatus may improve wearing comfort and achieve good display effects.

摘要： A wavelength conversion module (200) including an isolation structure layer (210), multiple wavelength conversion patterns (WCP1, WCP2), a dichroic filter film (220), and at least one dichroic filter layer (230) is provided. The isolation structure layer has multiple openings (OP). The wavelength conversion patterns are disposed in a part of the openings, and configured to absorb a first part of multiple excitation light beams (LBe) to generate multiple converted light beams (LBc). The dichroic filter film is disposed on one side of the isolation structure layer. The at least one dichroic filter layer is disposed on another side of the isolation structure layer or disposed in the openings. A part of the converted light beams are reflected back to the wavelength conversion patterns by the dichroic filter film. A second part of the excitation light beams, passing through the wavelength conversion patterns, are reflected back to the wavelength conversion patterns by the at least one dichroic filter layer.
