Description

A kind of display control chip and stereoscopic display device

Technical field

The present invention relates to stereo display field, relate in particular to a kind of display control chip and stereoscopic display device.

Background technology

Stereoscopic display device is the parallax feature of utilizing human eye, presents the stereopsis with spatial depth information, normally after synthetic by Pixel arrangement algorithm multiple views with parallax, outputs on three-dimensional display.This disparity map is directly delivered to beholder's right and left eyes, and then synthetic stereo image.

Naked-eye stereoscopic display device has not the additional peripheral devices such as wear a pair of spectacles, allows the advantages such as user watches under environment more freely; But, in current bore hole stereo display technique, have two phenomenons not meet human vision characteristics: 1, spectators move forward and backward stereoeffect variation and can produce the distortion of the Depth Distortion(degree of depth), 2, spectators' level or move up and down forever only sees that the stereo display effect of an angle can produce Motion Distortion(and move distortion).Fig. 1 is the schematic diagram about two kinds of distortions:

In Fig. 1 (a), in the time that spectators 105 move from original position to the position of the stereo display panel 103 away from tracking means 104 (moving to dotted line position from solid line position figure), the object object1 that is visually arranged in stereo display panel 103 front sides (approaching this side of spectators 105) spectators moves to dotted line position by more close spectators 105(figure from solid line position), the object object2 that is arranged in stereo display panel 103 rear sides (i.e. the side away from from spectators 105) will move to dotted line position from solid line position further from spectators 105(figure).

In Fig. 1 (b), when spectators 105 (moving to dotted line position from solid line position figure) when original position moves to the left, position after movement, it is identical that the angle of object object1, object2 that spectators 105 see in stereo display panel 103 is seen also and in situ time.

Fig. 1 (a) and (b) in two kinds of distortions all do not meet human eye vision custom, because in real life, when spectators are away from a scene time, it is large that the degree of depth of scene should be able to reduce instead of become, in the time approaching a scene, the degree of depth of scene can become large instead of diminish; When spectators are in the time that different angles is watched a scene, be can see blocking and remove the variation of blocking simultaneously, thereby see the different angles of scene, instead of only see an angle.

In the present embodiment, the parameter of described light-splitting device can comprise the width P of light-splitting device;

Described command process module indicates described spectral array drive control module that the width P of light-splitting device is updated to:

$P=(1-\frac{f}{D+f}).M;$

Wherein, D is the distance of current viewing location and described light-splitting device; M forms the width of the display unit that stereo-picture will cover for controlled light-splitting device; F is the distance between described light-splitting device and pixel planes; Described display unit represents a pixel, and a pixel comprises at least one sub-pixel.

In the present embodiment, the parameter of described light-splitting device can comprise side-play amount offset;

Described command process module indicates described spectral array drive control module that the side-play amount offset of light-splitting device is updated to:

offset=(D+f)/OFFSET。

Wherein, the side-play amount that OFFSET is current viewing location.

After Fig. 4 has shown that the light-splitting device as an example of LC-Lens example is combined with display floater, the Computing Principle of viewing distance; Wherein on display floater, pixel planes comprises pixel (also can be described as sub-pixel) some groups times, and every group has m time pixel, and m is positive number.
