Abstract

The present disclosure provides a display screen adjusting method, a display screen adjusting apparatus and a display device. The method comprises the steps of: acquiring visual angle information and fixation point position information of a user relative to a display screen; determining a reference point position to which the display screen needs to be adjusted according to the fixation point position information; and adjusting the angle and position of the display screen according to the visual angle information, the reference point position and the current position of the display screen in light of a predetermined rule. The display screen adjusting method, the display screen adjusting apparatus and the display device can automatically adjust the angle and position of the display screen simultaneously without manual operation, thereby improving the user'"'"'s viewing experience.

/or

adjusting the central position of the display screen to coincide with the reference point position according to the reference point position and the current position of the display screen.

3. The method according to claim 1, wherein the step of adjusting the angle and position of the display screen according to the visual angle information, the reference point position and the current position of the display screen in light of the predetermined rule comprises:

adjusting the angle of the display screen according to the visual angle information so as to make the plane of the adjusted display screen perpendicular to an bisector of an angle formed between the sight lines of the user'"'"'s two eyes; and

/or

adjusting the central position of the display screen to coincide with the reference point position according to the reference point position and the current position of the display screen.

4. The method according to claim 3, wherein the step of adjusting the angle and position of the display screen according to the visual angle information, the reference point position and the current position of the display screen in light of the predetermined rule also comprises:

when the fixation point position information is two positions where the sight lines of the user'"'"'s two eyes respectively intersect with the plane of the display screen, adjusting an edge of the display screen to be parallel to the line connecting the two positions where the sight lines of the user'"'"'s two eyes respectively intersect with the plane of the display screen.

5. The method according to claim 1, further comprising:

initiating a screen adjusting mode before acquiring the visual angle information and the fixation point position information; and

turning off the screen adjusting mode after adjusting the angle and position.

6. A display screen adjusting apparatus, comprising an eyeball detection arrangement, a processor and a motion controller connected with a display screen, wherein

the eyeball detection arrangement is configured to acquire visual angle information and fixation point position information of a user relative to the display screen, the visual angle information comprising an angle formed between the sight line of the user and a plane of the display screen, and the fixation point position information comprising the position where the sight line of the user intersects with the plane of the display screen;
