Automatic adjusting type display device and adjusting method thereof

The invention discloses an automatic adjusting type display device and an adjusting method thereof. The adjusting method comprises the steps of: obtaining and identifying a facial image of a user at the current spatial position by a receiving camera and determining the coordinate of the facial image of the user at the current spatial position in a spatial coordinate system; calculating a rotation angle of a displayer needed to be adjusted, with respect to the face, based on the coordinate of the spatial coordinate system, and controlling a motor driving device to drive the displayer to rotate respectively around X-axis, Y-axis and Z-axis of a space rectangular coordinate system by utilizing rotation angle feedback; receiving a distance from the face of the user located at the current spatial position and acquired by a distance sensor to the displayer, adjusting a cambered surface bending deformation amount of a substrate made of an electro-active polymer and located on the displayer based on the distance feedback so as to adaptively drive a soft screen attached on the surface of the substrate to bend. As the rotation angle and the bending cambered surface of the displayer is driven to be adjusted, the display device is guaranteed to be adjusted to adapt to spatial position change of the user in a movement process, and the display effect is guaranteed.
