The embodiment of the invention provides a naked eye 3D display method and system. The system comprises a display screen, a control circuit and a grating plate. The display screen obtains the video frame and displays the video frame; Wherein the video frame comprises a type identifier, and the type identifier is an identifier for indicating that the video frame is a left-eye video frame or an identifier for indicating that the video frame is a right-eye video frame; The control circuit obtains the type identifier, generates a grating control signal according to the type identifier, and sends the grating control signal to the grating plate; And the grating plate changes a stripe opening state according to the grating control signal. Therefore, the control circuit can acquire the type identifier in the video frame in real time, thereby accurately extracting the synchronization signal of the video frame, and compared with the prior art, the 3D display effect is improved.
Description
technical field [0001] The present invention relates to the technical field of three-dimensional stereoscopic display, and in particular, to a naked-eye 3D (three-dimensional, three-dimensional) display method and system. Background technique [0002] In recent years, three-dimensional stereoscopic display technology has developed rapidly. Among them, the naked-eye 3D technology enables users to experience the stereoscopic effect of 3D images without wearing any auxiliary equipment. [0003] The key point of naked-eye 3D technology is to simulate the principle of human eye stereoscopic imaging, which involves two important principles: the principle of binocular parallax and the persistence of vision effect. The principle of binocular parallax of the human eye means that there is a certain degree of horizontal difference between the images on the retinas of the left and right eyes due to the difference in pupil distance and gaze angle. Persistence of vision of the human eye ...
