Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to figure 1, the utility model multi-user comprises according to the liquid crystal television system better embodiment of sequential observation: LCD TV 10, the first switch glasses 20 and second switch glasses 30, described LCD TV 10 comprise image processing module 12, image display 14, audio frequency transmitter module 16 and glasses switching signal transmitter module 18.Described image processing module 12 is used to handle vision signal, described display module 14 is used for the screen display image in LCD TV 10, described audio frequency transmitter module 16 is used for the audio-frequency signal coding emission with vision signal, described glasses switching signal transmitter module 18 is used to launch the glasses switching signal of the first switch glasses 20 and second switch glasses 30, controlling the eyeglass of the first switch glasses 20 and second switch glasses 30 opens or closes, described first glasses comprise eyeglass switch 22 and earphone 24, described second glasses comprise eyeglass switch 32 and earphone 34, the eyeglass switch 22 of described first glasses and the eyeglass switch 32 of second glasses are used to receive the glasses switching signal, and described earphone 24 and 34 is used for receiving and decoded audio signal.
In better embodiment of the present utility model, the image processing module 12 of described LCD TV 10 is used to receive the two-path video signal 1 and the vision signal 2 of input, above-mentioned vision signal 1 and 2 can be TV programme or from the vision signal of other information source (for example DVD), image in 12 pairs of vision signals 1 of image processing module and 2 is handled, the image of vision signal 1 and 2 is carried out picture to intersect and sends to image display 14 after the stack and carry out image and show, with reference to figure 2, the time sequencing that concrete is according to the picture frame of vision signal, picture frame A1～the A4 of vision signal 1 is intersected stack with the picture frame B1～B4 of vision signal 2 successively, thereby make the image display 14 of LCD TV 10 obtain A1 successively, B1, A2, B2, A3, B3, A4, the picture frame of B4, therefore in screen every the image of frame display video signal 1 and vision signal 2, and then handle by the audio signal of 16 pairs of vision signals 1 of audio frequency transmitter module and 2, respectively with the transmission of encoding of different coded formats.It should be noted that, the frame frequency of supposing vision signal 1 and 2 all is F, the output frequency of graphics processing unit 14 then is 2F so, usually, in order to guarantee that the picture that the switch glasses are watched does not glimmer, the frame frequency of picture generally is not less than 60Hz, so the output frequency of graphics processing unit 14 just is not less than 120Hz.
Described glasses switching signal transmitter module 18 is according to the picture display timing generator (needing certain at interval vertical blanking period between the adjacent picture frame) of LCD TV 10 screens at this moment, output and the glasses switching signal sequential of vision signal 1 coupling and the glasses switching signal of mating respectively with vision signal 2, promptly export the glasses switching signal of the first switch glasses 20 and second switch glasses 30 respectively, the sequential chart of above-mentioned signal is with reference to figure 3.By this, the eyeglass of the first switch glasses 20 and second switch glasses 30 is opened when glasses television 10 display video signals 1 and vision signal 2 respectively, and by earphone 24 and 34 decode respectively acquisition vision signal 1 and 2 audio signal, thereby the content that makes two users watch vision signal 1 and 2 by first glasses 20 and second glasses 30 respectively.
Adopt above-mentioned principle can realize also that three users, four users even more users watch the display screen of a LCD TV 10 simultaneously and obtain different images and sound effect and non-interference.In order to obtain good display effect, the refresh rate of screen also needs corresponding raising, if three users watch, just the picture of three information sources need be intersected stack, the frame frequency of screen generally will be higher than 1 80Hz so, and four users watch simultaneously, just the picture of four information sources need be intersected stack, and then the frame frequency of screen will be higher than 240Hz.
Continuation is with reference to figure 4, it is the sequential chart of four users control timing of picture display timing generator and switch glasses when watching simultaneously, according to the sequential shown in the figure, can control glasses 1～4 respectively by the switching signal of glasses 1～4 and open successively, watch the picture of vision signal 1～4 respectively.
Should be understood that; the above only is a better embodiment of the present utility model; not in order to limit protection range of the present utility model; for those of ordinary skills; any modification of being done according to the above description, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
