Embodiment 1
[0038] This embodiment records a display device 10, such as figure 1 As shown, the display device 10 described in this embodiment includes:
[0039] The image source 11 is configured to generate an initial beam 111 corresponding to each first image information in the first image information set, and each first image information corresponds to the initial beam 111 to form an initial beam set;
[0040] In practical application, the image source 11 realizes the function of the display unit, specifically, it may be a projection display unit; the image information collection may be a series of continuous frame images in the video to be displayed; it may also be a series of image combinations and Correspondingly, each initial beam 111 in the initial beam set independently carries image information (such as a frame image), and each initial beam 111 includes a series of rays to form an image information correspondingly (such as a frame image in a video) a frame of an image, or an ima...
Embodiment 2
[0056] This embodiment records a display device 10, such as figure 2 As shown, the display device 10 described in this embodiment includes:
[0057] The image source 11 is used to generate an initial light beam set corresponding to the first image information set. In practical applications, the image source 11 can be a display unit, specifically, a projector (such as the aforementioned laser projector, a projector using DLP, etc.) can be used. computer or a projector using a 3LCD) to convert the first image information set into an initial light beam set;
[0058] Optical unit 12, comprising:
[0059] The light guide medium 121 can be made of glass and other materials with light beam refraction characteristics. When the surface of the light guide medium 121 has a beam collection incident on it, the light guide medium 121 transmits the incident beam collection in the form of refraction inside itself;
[0060] The first diffractive element 122 is arranged in the first area of ...
Embodiment 3
[0075] Embodiment 3 The image source includes two sub-image sources
[0076] This embodiment is based on the first embodiment and the second embodiment, and the realization process of the display is described in combination with the structure of the image source 11 described in the foregoing embodiments.
[0077] like Figure 11 As shown, the image source 11 recorded in the foregoing embodiments may include:
[0078] The first sub-image source 111, the irradiation range of the first sub-image source 111 includes at least the first area, and is used to add the first initial beam set sequentially generated based on the second image information in the second image information set Each of the first initial beams 1111, each first initial beam 1111 corresponds to a second image information in the second image information set, the first sub-image source 111 puts the first initial beams 1111 in the order of first The projection direction is sequentially projected into the light guid...
