Description

The display methods and device of 3D television interfaces
The display methods and engineering device technique field of 3D television interfaces are the present invention relates to 3D TV domains, in particular to the display methods and device of a kind of 3D television interfaces.Background technology
3D technology passes through the development of decades, gradually moves to maturity.Three-dimensional picture makes spectators seemingly on the spot in person, is more nearly the impression of real world.3D technology turns into the hot spot technology of TV industry, and present user is home-confined can just to enjoy shocking 3D videos.At present, 3D TVs on the market are main based on active 3D TVs, and the relative 3D TVs using aberration principle, active 3D TVs can provide the display effect become apparent from.But overwhelming majority 3D TVs are all original 2D master chip schemes plus 3D display screens at present（3D conversion systems are in exhibition；), so, 2D master chip can not be to UI (User Interface, user interface on active 3D TVs）Handled, so that when opening 3D patterns, OSD (On-Screen Display, screen display）Entanglement occurs, causes user can not be interacted with TV.Most directly it is exactly to increase hardware to handle the OSD under 3D for this problem.However, it is found by the inventors that：According to prior art, in order to reach the effect of 3D processing, increase is required for for the 3D osd generators of 3D TVs, so as to add product cost, put off time that product emerges and missed listing good opportunity, and above-mentioned hardware handles process is complex, the Jiang Shi efficiency of processing.The content of the invention is it is a primary object of the present invention to provide the display methods and device of a kind of 3D television interfaces, to solve the problem of display methods of the prior art increases product cost.To achieve these goals, just it is blunt according to one aspect of the present invention there is provided a kind of display methods of 3D television interfaces, it includes：The exhibition obtained under 2D shows osd information；OSD information under acquired 2D is converted into the osd information under 3D, wherein, the osd information under the 3D includes left eye OSD information and right eye osd information；Osd information under the 3D is sent to display device and shown. To achieve these goals, just it is blunt according to another aspect of the present invention there is provided a kind of display device of 3D television interfaces, it includes：Acquiring unit, for obtaining the screen display osd information under 2D；Converting unit, for the osd information being converted into the osd information under acquired 2D under 3D, wherein, the osd information under the 3D includes left eye osd information and right eye osd information；Transmitting element, shows for the osd information under the 3D to be sent to display device.Pass through the present invention, the osd information that osd information under acquired 2D is converted under 3D by 3D algorithms is turned using 2D, the problem of solving display methods increase product cost of the prior art, has reached the technique effect of conversion and display that osd information is realized in the case where not increasing hardware.Brief description of the drawings accompanying drawing described herein is used for providing a further understanding of the present invention, constitutes the part of the application, and schematic description and description of the invention is used to explain the present invention, does not constitute inappropriate limitation of the present invention.In the accompanying drawings：Fig. 1 is the flow chart of the display methods of 3D television interfaces according to embodiments of the present invention；Fig. 2 is a kind of preferred structure chart of the display device for the 3D television interfaces for occupying the embodiment of the present invention；Fig. 3 is another preferred structure chart of the just display device of the blunt 3D television interfaces according to the embodiment of the present invention；Fig. 4 is another preferred structure chart of the display device for the 3D television interfaces for occupying the embodiment of the present invention；Fig. 5 is another preferred structure chart of the display device for the 3D television interfaces for occupying the embodiment of the present invention.Embodiment describes the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can be mutually combined.Before embodiments of the present invention are described, the basic concepts of the present invention will be described first. The general principle of stereotelevision is parallax, mainly binocular parallax（Binocular parallax), the eyes of people are at a distance of about 6.5cm, people with eyes when object is watched, right and left eyes watch two width to omit the different images of Kai respectively, imaging also has difference on the eyes retina of left and right, and the sensation of solid will be produced through corticocerebral combined reaction --- here it is parallax creates three-dimensional.Therefore, collection/making right and left eyes image and right and left eyes are inputed to respectively, it is possible to allow people to see stereoscopic picture plane.And active 3D TVs exactly utilize this principle：3D signals show the image of left and right two in turn with 120Hz (or 240hz) frequency on a display screen after processing of circuit.Beholder need to wear a secondary liquid crystal glasses.Glasses are controlled with a switch synchronous with transmitting terminal, and when left-eye image occurs, the liquid crystal printing opacity of left eye, the liquid crystal of right eye is light tight；On the contrary, when eye image occurs, the only liquid crystal printing opacity of right eye.Left and right two can only see image required everywhere.Active electric full HD can show depending on being mainly characterized by, high resolution；2D display brightness and resolution ratio do not change；The resolution ratio that 3D is shown is identical with 2D.Left eye and the information of right eye that one two field picture of the 3D videos of active 3D TVs is included, then output is mixed with OSD and is FRC to 3D display screens, therefore OSD must will also have a correct display when display in right and left eyes information, and this exactly core of the invention.The Fig. 1 of embodiment 1 is the flow chart of the display methods of 3D television interfaces according to embodiments of the present invention, and it includes following step 4 and gathered：
