3D display system 1 is such as the display system that is the purposes such as computer screen (monitor), TV, all-in-one computer (all-in-one computer) or public's display.3D display system 1 for example is spectacle 3D display system or bore hole formula 3D display system, wherein spectacle 3D display system is such as for color separation spectacle, polaroid glasses formula or shutter glass type 3D display system etc., and bore hole formula 3D display system for example is based on lens pillar or based on dual-view or many views bore hole formula 3D display system of disparity barrier.
Fig. 2 is the flow chart of the How It Works of the display chip of 3D display system according to an embodiment of the invention.Take 3D display system 1 shown in Figure 1 as example, please be simultaneously with reference to Fig. 1 and Fig. 2, the How It Works of the display chip 11 of 3D display system 1 comprises the following steps.
At step S20, display chip 11 receives input video S
INInput video S
INCan come from wireless or the wired broadcasting video frequency program, or pass through such as Video Graphics Array (Video Graphics Array, VGA) terminal, HDMI (High Definition Multimedia Interface) (High Definition Multimedia Interface, HDMI) vision signal that receives of the video terminal such as terminal, or by reading such as the stored video content of the Storage Medias such as CD, Portable disk.Input video S
INCan be 2D video or 3D video, arrange about wherein the form of 3D video can be, be arranged above and below, collections of pictures, be staggered, line interlacing is arranged, checkerboard type is staggered, the 2D view adds the depth of field or the 2D view adds the form of the depth of field, background and the background depth of field etc.
At step S21, display chip 11 is judged input video S
INForm be 2D video or 3D video.For example, for the input video S that includes video format information
IN, in its message box (InfoFrame), recording video format information such as the video that adopts the HDMI standard, display chip 11 can be by reading input video S
INThe video format information that includes learns that input video is 2D video or 3D video.Again for example, for the input video S that does not include video format information
IN, such as the analog rgb video that transmits by the VGA terminal, 11 of display chips can detect and learn that input video is 2D video or 3D video by input video being carried out the XOR computing.Again for example, the user can be by user interface (user interface) (not illustrating) inputting user command S
CMDInform that display chip 11 input videos are 2D video or 3D video.
In addition, display chip 11 is by internal integrated circuit (Inter-Integrated Circuit, I
2C) interface or applicable communication interface read the panel parameter that is stored in display floater 12.This panel parameter comprises type, the Pixel arrangement mode of display floater and can present the information such as view number (such as dual-view or many views).This panel parameter can be recorded in EDID, E-EDID or other the applicable data structure, and is stored in the memory in the display floater 12.
At step S22 or S27, display chip 11 reads the watching mode of user's setting and judges that watching mode is 2D pattern or 3D pattern.The user can pass through user interface inputting user command S at any time
CMDSet the watching mode of wanting and be stored in the memory of display chip 11 inside or external memory, so that display chip 11 reads when needing again.
At step S23, the panel parameter that reads by step S21 is judged that 3D display system 1 is whether changeable and is the 2D pattern.
When display chip 11 is judged input video S at step S21
INFor the 2D video and when step S22 judges that the watching mode read is the 2D pattern, namely through step S21 and S22 to step S23, display chip 11 according to panel parameter judge 3D display system 1 whether changeable be the 2D pattern.If judge 3D display system 1 changeable be the 2D pattern, then to step S24 3D display system 1 is made as the 2D pattern and with the 2D video as output video S
OUTCan not switch to the 2D pattern if judge 3D display system 1, then to step S25 the picture size of 2D video is adjusted into single 3D view size and get its as the 3D view of all viewpoints with generation output video S
OUT
When display chip 11 is judged input video S at step S21
INFor the 2D video and when step S22 judges that the watching mode that reads is the 3D pattern, namely arrive step S26 through step S21 and S22, display chip 11 converts the 2D video to specific 3D video at step S26 first, converts specific 3D video the 3D video of suitable display floater 12 to as output video S at step S29 according to panel parameter again
OUT
When display chip 11 is judged input video S at step S21
INFor the 3D video and when step S27 judges that the watching mode that reads is the 2D pattern, namely arrive step S28 through step S21 and S27, display chip 11 is adjusted into arbitrary 3D view of the picture of 3D video full frame and gets it as the picture of 2D video at step S28 first, enters step S23 again and produces output video S respectively at step S24 or S25 according to 3D display system 1 is whether changeable for the 2D pattern
OUT
When display chip 11 is judged input video S at step S21
INFor the 3D video and when step S27 judges that the watching mode that reads is the 3D pattern, namely arrive step S29 through step S21 and S27, display chip 11 converts the 3D video 3D video of suitable display floater 12 to as output video S according to panel parameter
OUT
At last, at step S30, display chip 11 is with output video S
OUT Export display floater 12 to and watch picture to present.
In sum, the present invention is because adopting display chip to pass through such as I
2C interface or applicable communication interface read the panel parameter that prestores in the display floater that connects, and be that the watching mode that 2D or 3D video and user set is 2D or 3D pattern according to input video, automatically to input video carry out necessity and in real time conversion process produce the output video that is fit to and export display floater to and watch picture to present, therefore can support all types of display floaters and different video input and output demands by one chip.System manufacturer no longer needs to hoard the display chip of various models and adopts corresponding display chip and peripheral circuit design for dissimilar display floaters and different video input and the output demands of different client, greatly saves required time and the funds of 3D display system exploitation.And, after dispatching from the factory, the 3D display system also can change dissimilar display floaters according to situation, and can improve display floater source elasticity, simplify the maintenance of 3D display system and reduce shutdown loss.
Although the present invention discloses as above with preferred embodiment; right its is not for limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim person of defining.
