Optical unit 12, including：

First diffraction part 122, is arranged on the first area of the light guide media 121, and the first diffraction part 122 is located at institute State at least part of range of exposures of each first incipient beam of light 1111 of incipient beam of light set, the first diffraction part 122 can be adopted Processed with realizing the diffraction to light beam set with optical grating construction, it is thus possible to be internally formed correspondence institute in the light guide media 121 State in the first incipient beam of light set the 1111 of each first incipient beam of light, first refractive light beam set 1221；

As shown in figure 3, when the 3rd diffraction part 123 forms the first visible beam set based on the set of first refractive light beam, and When forming the second visible beam set based on the second deflecting light beams set, correspondingly, the first visible beam is integrated into described first Being formed with the corresponding exit direction of visible beam set makes eyes of user completely perceive second image information set (the first figure As at least part of information of information aggregate, each second image information in the second image information set is based on priority time sequencing Show, so as to project human eye can have video playback effect, or similar magic lantern play effect) the first visible area Domain, second visible beam is integrated into be formed with the corresponding exit direction of the second visible beam set makes eyes of user (at least part of information of the first image information set be (the first image information set completely to perceive the 3rd image information set At least part of information, each second image information in the second image information set is being shown based on priority time sequencing, so as to throw Be mapped to human eye can have video playback effect, or similar magic lantern play effect) the second viewing area 1244, first can Each first light beam 1231 in depending on light beam set be used for carry the second image information set in different time shown it is each Second image information (each second image information can correspond to a two field picture), individual second in the second visible beam set can It is used to carrying in the 3rd image information set that (each the in each 3rd image information not shown in the same time depending on light beam 1242 Three image informations can correspond to a two field picture)；

In figure 3, exemplarily, first viewing area 1243 is identical with the part of the second viewing area 1244, Also just say that the first viewing area 1243 and the second viewing area 1244 there may be the region that partially overlaps, the triangle in correspondence Fig. 3 Shape region namely the 3rd viewing area, the 3rd viewing area is that the viewing areas of the first image information set (can be while see Second image information set and the 3rd image information set)；Certainly, when the first visible beam set 1241 and second in Fig. 3 But light beam set 1242 perpendicular to light guide media 121 when, the first viewing area 1243 is not deposited with the second viewing area 1244 In overlapping region.

Second image information set and the 3rd image information are the part in the first image information set, with reference to tool Body example is said with regard to the different relations of the first image information set, the second image information set and the 3rd image information set It is bright.

Example 1) each 3rd figure in the second image information set in each second image information and the 3rd image information set As information it is entirely different (there is no commons factor, namely there is no the image information of overlap), the second image information set and the 3rd figure As the union of information aggregate is the first image information set.

User 1 and user 2 carry out snipsnapsnorum based on display device 10, and user 1 and user 2 need to watch respective bottom Board information and can not be seen by other side；As shown in figure 4, when user 1 is located at the first viewing area 1243, carrying the second figure As each eyes of first visible beam, 1241 sequential illumination access customer 1 in the first visible beam set of information aggregate, user 1 is made Watch the second image information set, wherein the 3rd image information in the second image information set as shown in fig. 6, including The card in one's hand information of user 1；When user 2 is located at the second viewing area 1244, carry the 3rd image information set second can Each eyes of 3rd visible beam, 1242 sequential illumination access customer 2 in depending on light beam set, make user 2 watch the 3rd image information Set, wherein the 3rd image information set is as shown in figure 5, including the card in one's hand information of user 2；So, user 1 and user 2 are located at The different viewing areas of display device 10, you can watch different image informations, realize in interaction scenarios to different use Family shows different image informations.

It is pointed out that when user 1 and user 2 are located at three viewing areas, due to the 3rd viewing area existing first Visible beam set outgoing, there is the second visible beam set outgoing again, therefore user 1 and user 2 can be in the 3rd viewing areas See the second image information set and the 3rd image information set (namely first image information set), user 1 and user 2 simultaneously The schematic diagram of the first image information set seen in the 3rd viewing area is as shown in Figure 7.

Example 2) the first image information set is identical with the second image information set part (there is common factor, namely there is weight Folded parts of images information), the union of the second image information set and the 3rd image information set is the first image information set.

Still by taking above-mentioned snipsnapsnorum as an example, user 1 and user 2 except needing to see respective card in one's hand information, and Need to see jointly the animation dealt out the cards, correspondingly, image source 11 projects the incipient beam of light set 111 of the first diffraction part 122 and holds The first image information set is loaded with, a frame of the card in one's hand information of each first image information corresponding deal out the cards animation and user 1 Image, correspondingly, the first visible beam set 1241 also carries deal out the cards animation and the first image information set；Image source 11 is thrown The incipient beam of light set 111 for being mapped to the second diffraction part 123 carries the second image information set, each the second image information correspondence Deal out the cards animation and user 2 card in one's hand information a two field picture, correspondingly, the second visible beam set 1242 also carry send out Board animation and the card in one's hand information of user 2；

As shown in figure 3, when user 1 is located at the first viewing area 1243, carrying the first of the first image information set Each eyes of first visible beam, 1241 sequential illumination access customer 1 in visible beam set, make user 1 watch the second image to believe Each second image information in breath set, wherein second image information (such as one frame in the second image information set Image) as shown in figure 8, the card in one's hand information and the corresponding two field picture of animation of dealing out the cards including user 1；

When user 2 is located at the second viewing area 1244, the second visible light constriction of the 3rd image information set is carried Close 1242 and irradiate the eyes of access customer 2, make user 2 watch the 3rd image information set, wherein the 3rd image information set such as Fig. 9 It is shown, including the card in one's hand information of user 2 and animation of dealing out the cards；So, user 1 and user 2 are located at the different displays of display device 10 Region, you can see that identical is dealt out the cards animation and each self-corresponding card in one's hand information, is realized in interaction scenarios to difference jointly User shows different image informations.

It is pointed out that when user 1 and user 2 are located at three viewing areas 1245, due to the 3rd viewing area it is existing The outgoing of first visible beam set 1241, there is an outgoing of the second visible beam set 1242 again, therefore user 1 and user 2 can be The second image information set and the 3rd image information set (namely the first image information sets are seen simultaneously in 3rd viewing area 1245 Close), the schematic diagram of the first image information set that user 1 and user 2 see in the 3rd viewing area 1245 is as shown in Figure 10.

Example 3) the second image information set and the 3rd image information set identical with the first image information set ( Two image information set are the maximal subset of the first image information set with the 3rd image information set), that is to say, that show Equipment 10 can not only realize that the differentiation of the user of different viewing areas shows, can also be in the user of different viewing areas Existing identical image information, it is contemplated that in the scene of multi-user collaborative operation, user may need to see that identical image is believed Breath (such as the victory or defeat score information of game shown during game over), therefore, it can according to actual scene demand, display device 10 can be in the first display pattern (showing different image informations to the user of different viewing areas) and the second display pattern Switch between (showing same image information to the user of different viewing areas).

The image source of embodiment three includes the situation of two sub- image sources
