Optical unit 12, comprising:

First diffraction part 122, be arranged on the first area of described light guide media 121, described first diffraction part 122 is positioned at least part of range of exposures of each first incipient beam of light 1111 of described incipient beam of light set, first diffraction part 122 can adopt optical grating construction to realize the diffraction process to light beam set, thus can form 1111 of each first incipient beam of light in corresponding described first incipient beam of light set in described light guide media 121 inside, 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, first visible beam is integrated into exit direction corresponding to described first visible beam set be formed and makes that eyes of user is complete perceives the second image information set (at least part of information of the first image information set, each second image information in second image information set is showing based on priority time sequencing, thus project the effect that human eye can have video playback, or the effect play of similar magic lantern) the first viewing area, described second visible beam is integrated into exit direction corresponding to described second visible beam set be formed and makes that eyes of user is complete perceives the 3rd image information set (at least part of information (at least part of information of the first image information set of the first image information set, each second image information in second image information set is showing based on priority time sequencing, thus project the effect that human eye can have video playback, or the effect play of similar magic lantern) the second viewing area 1244, each first light beam 1231 in first visible beam set is for carrying each second image information (each second image information can a corresponding two field picture) of carrying out showing at different time in the second image information set, the second visible beam 1242 in second visible beam set is for carrying in the 3rd image information set in each 3rd image information of not carrying out in the same time showing (each 3rd image information can a corresponding two field picture),

In figure 3, exemplarily, described first viewing area 1243 is identical with described second viewing area 1244 part, also just say that the first viewing area 1243 and the second viewing area 1244 can exist the region that partially overlaps, delta-shaped region in corresponding diagram 3 is also the 3rd viewing area, and the 3rd viewing area is the viewing areas (simultaneously can see the second image information set and the 3rd image information set) of the first image information set; Certainly, when the first visible beam set 1241 in Fig. 3 and second light beam set 1242 is perpendicular to light guide media 121 time, namely there is not overlapping region in the first viewing area 1243 and the second viewing area 1244.

Second image information set and the 3rd image information are the part in the first image information set, are described below in conjunction with the different relations of concrete example with regard to the first image information set, the second image information set and the 3rd image information set.

Example 1) each second image information is completely different from each 3rd image information in the 3rd image information set in the second image information set (there is not common factor, namely there is not overlapping image information yet), the union of the second image information set and the 3rd image information set 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 the respective card in one's hand information of viewing and can not be seen by the other side; As shown in Figure 4, when user 1 is positioned at the first viewing area 1243, carry each first visible beam 1241 sequential illumination access customer 1 eyes in the first visible beam set of the second image information set, user 1 is made to watch the second image information set, the 3rd image information wherein in the second image information set as shown in Figure 6, comprises the card in one's hand information of user 1; When user 2 is positioned at the second viewing area 1244, carry each 3rd visible beam 1242 sequential illumination access customer 2 eyes in the second visible beam set of the 3rd image information set, user 2 is made to watch the 3rd image information set, wherein the 3rd image information set as shown in Figure 5, comprises the card in one's hand information of user 2; Like this, user 1 and user 2 are positioned at the different viewing areas of display device 10, can watch different image informations, achieve and show different image informations to different user in interaction scenarios.

It is to be noted, when user 1 and user 2 are positioned at the 3rd viewing area, due to the existing first visible beam set outgoing in the 3rd viewing area, there is again the second visible beam set outgoing, therefore user 1 and user 2 can see the second image information set and the 3rd image information set (also i.e. the first image information set) simultaneously in the 3rd viewing area, and the schematic diagram of the first image information set that user 1 and user 2 see in the 3rd viewing area as shown in Figure 7.

Example 2) the first image information set identical with the second image information set part (exist and occur simultaneously, also namely there is overlapping 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 for above-mentioned snipsnapsnorum, user 1 and user 2 see respective card in one's hand information except needing, and need jointly to see the animation of dealing out the cards, correspondingly, the incipient beam of light set 111 that image source 11 projects the first diffraction part 122 carries the first image information set, a two field picture of the card in one's hand information of each first image information corresponding deal out the cards animation and user 1, correspondingly, the first visible beam set 1241 also carries deal out the cards animation and the first image information set; The incipient beam of light set 111 that image source 11 projects the second diffraction part 123 carries the second image information set, a two field picture of the card in one's hand information of each second image information corresponding deal out the cards animation and user 2, correspondingly, the second visible beam set 1242 also carries the card in one's hand information of deal out the cards animation and user 2;

As shown in Figure 3, when user 1 is positioned at the first viewing area 1243, carry each first visible beam 1241 sequential illumination access customer 1 eyes in the first visible beam set of the first image information set, user 1 is made to watch each second image information in the second image information set, second image information (such as a two field picture) wherein in the second image information set as shown in Figure 8, comprises the two field picture that the card in one's hand information of user 1 is corresponding with animation of dealing out the cards;

When user 2 is positioned at the second viewing area 1244, the the second visible beam set 1242 carrying the 3rd image information set is irradiated into user 2 eyes, user 2 is made to watch the 3rd image information set, wherein the 3rd image information set as shown in Figure 9, comprises the card in one's hand information of user 2 and animation of dealing out the cards; Like this, user 1 and user 2 are positioned at the different viewing areas of display device 10, jointly can see identical deal out the cards animation and each self-corresponding card in one's hand information, achieve and show different image informations to different user in interaction scenarios.

It is to be noted, when user 1 and user 2 are positioned at the 3rd viewing area 1245, due to existing first visible beam set 1241 outgoing in the 3rd viewing area, there is again the second visible beam set 1242 outgoing, therefore user 1 and user 2 can see the second image information set and the 3rd image information set (also i.e. the first image information set) simultaneously in the 3rd viewing area 1245, and the schematic diagram of the first image information set that user 1 and user 2 see in the 3rd viewing area 1245 as shown in Figure 10.

Example 3) the second image information set and the 3rd image information set all identical with the first image information set (the second image information set and the 3rd image information set are the maximal subset of the first image information set), that is, display device 10 can not only realize the differentiation display of the user of different viewing area, identical image information can also be presented to the user of different viewing area, consider in the scene of multi-user collaborative operation, user may need to see identical image information (the victory or defeat score information of game as shown during game over), therefore, can according to the scene demand of reality, display device 10 can switch between the first display mode (namely showing different image informations to the user of different viewing area) and the second display mode (namely showing same image information to the user of different viewing area).
