Description
Technical field
The present invention relates to a kind of three-dimensional display of various visual angles, particularly a kind of three-dimensional display of various visual angles of the type of drive that does not change display floater.
Background technology
The main principle of stereo display technique is to make beholder's left eye receive different images respectively with right eye; And the image that left eye and right eye receive can be via brain analysis and overlapping and make the beholder perceive the stereovision and the degree of depth of image frame, and then produces third dimension.
3 d display device mainly can be distinguished time series formula (time-sequential) and two kinds of spatial multiplexing formulas (spatial-multiplexed) at present.Time series formula 3 d display device can be with scan mode Alternation Display confession in regular turn left eye left eye picture of watching and the right eye picture that supplies eye viewing.When watching picture; The beholder must wear shutter glasses (shutter glass); And shutter glasses can allow that in regular turn beholder's left eye only watches the left eye picture and can't watch the right eye picture according to present picture displayed; And the right eye of allowing the beholder only watches the right eye picture and can't watch the left eye picture, reaches the effect of stereo display by this.
Spatial multiplexing formula 3 d display device mainly comprises parallax shielding (parallax barrier) type 3 d display device.The utilization of parallax barrier type 3 d display device is arranged at the parallax shielding panel in display floater the place ahead, and left eye and the right eye that makes the beholder receives covering of disparity barrier because of the difference of viewing angle, and only can watch left eye picture and right eye picture respectively.Usually in order to carry out the switching of two-dimensional/three-dimensional (2D/3D) image; So be to utilize the liquid crystal panel of another sheet to be used as the parallax shielding, in the time will showing bidimensional image, second liquid crystal panel can present bright attitude (bright state); Let and to pass through through all light behind first liquid crystal panel; And will show 3-dimensional image the time, then the liquid crystal panel of this sheet then presents bright attitude and the dark alternate state of attitude (dark state), is equivalent to black and transparent alternate linear fringe.
Because the driving of delegation of the necessary delegation of parallax shielding panel; So the driving of display floater must cooperate the parallax shielding panel to change to the scan mode of delegation of delegation; But this kind type of drive is quite inconvenient, and the data of display floater and driving all need otherwise designed and can not use existing product.
Summary of the invention
