Description
Technical field
The present invention relates to a kind of display device, in particular to a kind of 3 d display device.
Background technique
In recent years, more true to nature closer to true image in order to pursue, display technology, which is constantly weeded out the old and bring forth the new, makes its fitting
The demand of observer.The pursuit for resolution ratio and color is shown from the plane at initial stage, until three-dimensional display apparatus in recent years more may be used
Further provide for three-dimensional sense of the observer other than image by.
The main action principle of stereoscopic display is the image of the viewing object for the angle that feeding right and left eyes are different respectively, according to
Two images of different parallaxes (parallax) are seen respectively depending on same image content but had to the visual characteristic of human eye in eyes
When, observer can feel that regarded object has stereovision and sense of depth, to experience a three-dimensional space stereopsis.
Using it is upper can be divided into generally need to additionally arrange in pairs or groups glasses viewing or directly naked view two ways, it is more main in recent years
Technology develops more based on the latter.It is different further in accordance with the mode of feeding, it is sub-divided into time domain multitask and spatial multiplexing
Mode.
Fig. 1 is schematic diagram of the prior art using the projection 3 d display device 1 of spatial multiplexing mode, as schemed institute
Show, the prior art using spatial multiplexing mode projection 3 d display device 1 include backlight 11, display device 12 and
Lens array 13.The pixel that the lens 14 of lens array 13 export pixel 15 ', 15 ", 15 " ' is directed toward three different space bits
Set 16 ', 16 ", 16 " '.In a similar manner, the pixel that the lens 14 ' of lens array 13 also export pixel 15 ', 15 ", 15 " '
It is directed toward three different spatial positions 17 ', 17 ", 17 " '.
