Abstract

A display control method, device and system are provided. The display control method comprises: displaying other sub-pixel views, except a 3D left-eye visual view and a 3D right-eye visual view, of a display module to be same 2D views; and obtaining corresponding 2D viewing position adjustment information capable of allowing both a left eye and a right eye of a 2D viewer to watch the 2D view according to eye position information of each 2D viewer, and outputting the 2D viewing position adjustment information. The proposal can achieve glasses-free 3D display and 2D display at the same time and satisfy the viewing requirements of different viewers at the same time.

First claim

The invention claimed is:

1. A display control method, comprising:
allowing sub-pixel views, other than a 3D left-eye visual view and a 3D right-eye visual view, of a display module to display a same 2D view;
obtaining corresponding 2D viewing position adjustment information capable of allowing both a left eye and a right eye of a 2D viewer to watch the 2D view according to eye position information of each 2D viewer, and outputting the 2D viewing position adjustment information;
determining a primary 3D viewer who is the nearest to the screen center according to eye position information of at least one 3D viewer; and
adjusting a position of a grating of a liquid crystal grating module according to the eye position information of the primary 3D viewer, so that a left eye and a right eye of the primary 3D viewer can respectively watch the 3D left-eye visual view and the 3D right-eye visual view with maximum brightness,
wherein the 2D viewing position adjustment information is: a minimum position adjustment distance from which both the left eye and the right eye of the 2D viewer can watch the 2D view,
there are at least two 3D viewers, as for each secondary 3D viewer except the primary 3D viewer, the method further comprises:
obtaining corresponding 3D viewing position adjustment information capable of allowing a left eye and a right eye of the secondary 3D viewer to respectively watch the 3D left-eye visual view and the 3D right-eye visual view according to eye position information of the secondary 3D viewer, and outputting the 3D viewing position adjustment information, and
wherein the 3D viewing position adjustment information is: a minimum position adjustment distance from which the left eye and the right eye of the secondary 3D viewer can respectively watch the 3D left-eye visual view and the 3D right-eye visual view.

2. The display control method according to claim 1 , wherein the 2D view and the 3D left-eye visual view or the 3D right-eye visual view display a same image.

3. A display control device, comprising:
a display operative to allow sub-pixel views, other than a 3D left-eye visual view and a 3D right-eye visual view, of a display panel to display a same 2D view;
a controller being in signal connection with the display and operative to:
obtain corresponding 2D viewing position adjustment information capable of allowing both a left eye and a right eye of a 2D viewer to watch the 2D view according to eye position information of each 2D viewer and output the 2D viewing position adjustment information;
determine a primary 3D viewer who is the nearest to a screen center according to eye position information of at least one 3D viewer;
adjust a position of a grating of a liquid crystal grating panel according to the eye position information of the primary 3D viewer, so that a left eye and a right eye of the primary 3D viewer can respectively watch the 3D left-eye visual view and the 3D right-eye visual view with maximum brightness; and
obtain corresponding 3D viewing position adjustment information capable of allowing a left eye and a right eye of a secondary 3D viewer to respectively watch the 3D left-eye visual view and the 3D right-eye visual view according to eye position information of the secondary 3D viewer and outputting the 3D viewing position adjustment information, as for each secondary 3D viewer except the primary 3D viewer when there are at least two 3D viewers,
wherein the 2D viewing position adjustment information is: a minimum position adjustment distance from which both the left eye and the right eye of the 2D viewer can watch the 2D view, and
wherein the 3D viewing position adjustment information is: a minimum position adjustment distance from which the left eye and the right eye of the secondary 3D viewer can respectively watch the 3D left-eye visual view and the 3D right-eye visual view.

4. The display control device according to claim 3 , wherein the 2D view and the 3D left-eye visual view or the 3D right-eye visual view display a same image.

5. A display control system, comprising:
a display panel;
a liquid crystal grating panel disposed in front of the display panel;
a signal receiver operative to receive view type selection signals of viewers; and
a human eye sensor operative to detect human eye position information;
a controller being in signal connection with the display panel, the liquid crystal grating panel, the signal receiver and the human eye sensor respectively and operative to
allow sub-pixel views, other than a 3D left-eye visual view and a 3D right-eye visual view, of the display panel to display a same 2D view;
obtain corresponding 2D viewing position adjustment information capable of allowing both a left eye and a right eye of a 2D viewer to watch the 2D view according to eye position information of each 2D viewer and output the 2D viewing position adjustment information;
determine a primary 3D viewer who is the nearest to a screen center according to eye position information of at least one 3D viewer;
adjust a position of a grating of a liquid crystal grating panel according to the eye position information of the primary 3D viewer, so that a left eye and a right eye of the primary 3D viewer can respectively watch the 3D left-eye visual view and the 3D right-eye visual view with maximum brightness; and
obtain corresponding 3D viewing position adjustment information capable of allowing a left eye and a right eye of a secondary 3D viewer to respectively watch the 3D left-eye visual view and the 3D right-eye visual view according to eye position information of the secondary 3D viewer and output the 3D viewing position adjustment information, as for each secondary 3D viewer except the primary 3D viewer when there are at least two 3D viewers,
wherein the 2D viewing position adjustment information is: a minimum position adjustment distance from which both the left eye and the right eye of the 2D viewer can watch the 2D view, and
wherein the 3D viewing position adjustment information is: a minimum position adjustment distance from which the left eye and the right eye of the secondary 3D viewer can respectively watch the 3D left-eye visual view and the 3D right-eye visual view.

6. The display control system according to claim 5 , wherein the 2D view and the 3D left-eye visual view or the 3D right-eye visual view display a same image.
