[0022] FIG. 2 is a flow chart showing a method of operating a display wafer of a 3D display system in accordance with an embodiment of the present invention. Taking the 3D display system shown in Figure 1 as an example, please also use «'«1 and Figure 2 to show the operation of Jingchuan including the following steps. The display wafer n receives the input video s at step S2 ’ '. Input view

IN sIN can be received from wireless or cable broadcast video programs, or through video terminals such as Video Graphics Array (VGA) terminals and High Definition Multimedia In_ terface (HDMI) terminals. Video signal, or by reading video content stored on a storage medium such as a disc or a flash drive. The input view silSIN can be 2D video or 3D video, wherein the format of the 3d video can be left and right, up and down, picture set, field staggered, line staggered, checkerboard staggered, 2D view plus depth of field or 2d view plus depth of field, Background and background depth of field format. 〇 In step S21, the display wafer 11 determines that the format of the input video s is

IN 2D video or 3D video. For example, for an input video SIN containing video format information, if video information using the HDMI standard is recorded in the information frame (InfoFrame), the display chip can be obtained by reading the video format information contained in the input video sIN. It is known that the input video is 2D video or 3D video. For example, for an input video SIN that does not include video format information, such as analog RGB video transmitted through the VGA terminal, the display chip 11 can detect that the input video is 2D video or 3D video by performing X0R operation on the input video. For another example, the user can input the user command s through the user 100117521 form number A0101 page 8 / page 161002029434-0 201249168 "user interface (not shown) _ CMD surgery D ° display wafer 11 input video is 2D video or 3D video. [0024] Furthermore, the display chip 11 reads the panel parameters stored in the display panel 12 through the internal integrated circuit Gnter-Integrated Circuit 'I2C' interface or a suitable communication interface. Information such as the type of display panel, the arrangement of pixels, and the number of views that can be rendered (such as dual view or multi view). This panel parameter can be recorded in kEDid, iedid or other applicable data structures and stored in display panel 12. In step S22 or S27, the display wafer 11 reads the user-set viewing mode and determines that the viewing mode is the 2D mode or the 3D mode. The user can input the user command sCMD through the user interface at any time to set the desired viewing mode and store it on the display chip. 11 internal memory or external memory for reading the wafer 11 as needed. [0026] Ο [0027] At step S2 3 'determining whether the 3D display system 1 can be switched to the 2d mode by the panel parameters read in step S21. When the display chip 11 determines in step S21 that the input video SIM is 2D video

When it is judged in step S22 that the read viewing mode is the 2D mode, that is, through steps S21 and S22 to step S23, the display wafer 11 judges whether or not the 3D display system 1 can be switched to the 2D mode based on the panel parameters. If it is judged that the 3D display system 1 can be switched to the 2D mode, the 3D display system 1 is set to the 2D mode and the 2D video is used as the output video S〇UT in step S24. If it is determined that the 3D display system 1 cannot be switched to the 2D mode, then the screen size of the 2D video is adjusted to a single 3D view size and taken as a 3D view of all viewpoints to produce 100117521 in the step S25. Form number A0101 Page 9 of 16 1000029434-0 201249168 [0028] [0032] [0032] The video is output. When the display wafer 11 determines in step S21 that the input video is 2D video and determines in step S22 that the read viewing mode is the 3D mode, that is, through steps S21 and S22 to step S26, the display wafer 11 first converts the 2D video in step S26. In a specific 3D video, a specific 3D video is converted into a 3D video suitable for the display panel 12 as an output video according to the panel parameters in step S29. When the display wafer 11 determines in step S21 that the input video S τ is 3D video IN and determines in step S27 that the read viewing mode is the 2D mode, that is, after steps S21 and S27 to step S28, the display wafer 11 is first in the step. S28 adjusts any 3D view of the 3D video screen to full screen and takes it as a 2D video screen, and proceeds to step S23 to generate an output video in step S24 or S25 according to whether the 3D display system 1 can be switched to the 2D mode. When the display wafer 11 determines in step S21 that the input video SIN is 3D video and determines in step S27 that the read viewing mode is the 3D mode, that is, through steps S21 and S27 to step S29, the display wafer 11 will be 根据3D according to the panel parameters. The video is converted into 3D video suitable for the display panel 12 as the output video S. Finally, in step S30, the display wafer 11 outputs the output video to the display panel 12 to present the viewing picture. In summary, the present invention employs a display chip. Read the pre-stored panel parameters in the connected display panel through the I2C interface or the applicable communication interface, and set the 2D or 3D video and user settings according to the input video. The viewing mode is 2D or 3D mode, and the input video is automatically converted and converted instantly. 100117521 Form No. A0101 Page 10/16 pages 1002029434-0 201249168 Processing produces a suitable output video output to the display panel to present the viewing picture, so it can be single The chip supports various types of display panels and different video input and output requirements. System manufacturers no longer need to hoard various types of display chips and different video input and output requirements for different types of display panels and different customers to adopt corresponding display chips. And the peripheral circuit design greatly saves the time and expense required for the development of the 3D display system. Moreover, after the 3D display system is shipped, different types of display panels can be changed according to the situation, which can improve the elasticity of the display panel and simplify the maintenance of the 3D display system.
