    摘要： The present invention relates to a large-size bionic holographic three-dimensional dynamic display method with large field of view. The method includes: a computer generated hologram (CGH) is loaded on a spatial light modulator; a large field angle is formed by changing the optical path through a microlens array or a diffractive optical element having same optical property with the microlens array disposed on a light-emitting surface of pixel structure of the spatial light modulator. Each microlens of the microlens array has one-to-one correspondence with each pixel of the pixel structure of the spatial light modulator. The cost is saved and design of the system structure is simplified while field view of the three-dimensional holographic display is expanded and large size is reappeared. The pixels in the spatial light modulator are fully utilized to avoid loss of resolution, and the display precision is provided to meet the growing demand of people.

    摘要： An autostereoscopic display device uses an electroluminescent display. A set of pixels is provided beneath view forming elements (such as lenses), with a plurality of pixels across the view forming element width direction. The pixels are arranged with at least two different angular orientations with respect to the substrate. The out-coupling performance is improved by arranging for the light emission direction to be substantially perpendicular to the desired emitting surface of the view forming elements.

    摘要： Embodiments of the present application disclose a light field display control method and apparatus and a light field display device. The light field display control method comprises: determining at least one depth distribution sub-region of content according to a display depth of field (DoF) range of a light field display device and depth distribution information of the content, wherein each depth distribution sub-region of the at least one depth distribution sub-region is located outside the display DoF range; and tilting a first display unit at least with respect to an original plane of a display array of the light field display device according to the display DoF range of the light field display device and the depth distribution sub-region, wherein the first display unit is a display unit that is in the display array and affects display of a first object, and the first object is a part, which is located in the depth distribution sub-region, of the content. The present application can improve display quality of an object, which is located in a partial depth distribution sub-region, of content to be displayed or content being displayed.
