The invention relates to a true 3D display driving method aimed at a display card of a computer. The method comprises the following steps: an implanted rendering data interception technology is adopted between a 3D visualization program and the display card to capture an original single channel color signal, a depth signal, a 3D scene transformation matrix and a projection transformation matrix; rasterized 3D data is reconstructed by parsing the information; on the basis of the stereo vision principle, the scene is re-transformed to two different viewpoint positions in a self-adapting manner, so that a binocular vision stereopair to be displayed in a 3D form is formed, and the display card is driven to output the binocular vision stereopair in a 3D form; and polarization, a pair of red and green or blinking glasses, and the like are adopted for true 3D display and observation. The invention can realize true 3D scene display of the prior 3D visualization software without changing programs and operation modes.

The invention provides a display picture adjusting method and device of a rotary display screen and the rotary display screen, belongs to the technical field of display, and can at least partially solve the problem of color cast of an existing rotary display screen due to low gray scale pixels. The invention discloses a method for adjusting a display image of a rotary display screen, wherein the rotary display screen comprises a plurality of pixels distributed in an array and can rotate at a specific angular speed by taking a line which is parallel to the column pixels and passes through the rotary display screen as an axis, the rotary display screen displays different pictures in different phases, and the method comprises the following steps: determining a first gray-scale threshold valueaccording to the characteristics of the rotary display screen; comparing the gray value of the lightened pixel in the image of the current phase with a first gray scale threshold value; and if the gray value of the lightened pixel in the image of the current phase is smaller than the first gray scale threshold value, taking the pixel as a to-be-adjusted pixel, adjusting the gray scale value of the to-be-adjusted pixel to zero gray scale, and performing gray scale compensation on the pixel close to the to-be-adjusted pixel.

The invention relates to a true 3D display method oriented to Google Earth and Sketch Up. The method comprises the following steps: an implanted rendering data interception technology is adopted between invoking of a 3D API of software and display by a display card to capture an original single channel color signal, a depth signal, a 3D scene transformation matrix and a projection transformation matrix; rasterized 3D data is reconstructed by parsing the information; on the basis of the stereo vision principle, the scene is re-transformed to two different viewpoint positions in a self-adaptingmanner, so that a binocular vision stereopair to be displayed in a 3D form is formed, and the display card is driven to output the binocular vision stereopair in a 3D form; and polarization, a pair of red and green or blinking glasses, and the like are adopted for true 3D display and observation. The invention can realize true 3D scene display of the prior software such as Google Earth and SketchUp without changing programs and operation modes.

Higher definition three-dimensional display is easily realized. A lenticular lens (2) is disposed so that the lengthwise directions of individual cylindrical lenses (2A) become parallel to the longitudinal direction (Y) of a two-dimensional display section (1). A plurality of lights corresponding to a plurality of view angles are radiated in the space in a plane divisional manner, and the relative positional relation between the pixels of each cylindrical lens (2A) and the two-dimensional display section (1) is periodically changed to periodically change the radiation direction of the displayimage light from arbitrary pixel of each cylindrical lens (2A). An image corresponding to one frame of a three-dimensional video image is displayed in a time divisional manner for each pixel of the two-dimensional display section (1), and the timing of time divisional display in the two-dimensional display section (1) and the timing at which change means changes the relative positional relation are controlled synchronously. This provides three-dimensional display with the plane division manner combined with the time division manner, achieving higher definition three-dimensional display.
