Automatic adjusting type display device and adjusting method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the field of display device manufacturing, in particular to an automatic adjustment type display device and an adjustment method. Background technique [0002] In daily life, the current viewing angle adjustments of displays (such as computer display devices, televisions, etc.) are passive and require manual adjustment. To meet the requirements of the viewer's viewing angle. [0003] However, with the deepening of the humanized design of display devices, curved screens appear on display screens, which provide people with a better viewing angle. However, even this kind of curved screen only alleviates and adapts to the viewing angle of the viewer to a certain extent through the curved surface of the screen, and it still cannot automatically adjust the viewing angle (that is, the angle of this display with a curved screen structure needs to be adjusted by the user himself. change by hand), and the curvature of the curved screen...

However, even this kind of curved screen only alleviates and adapts to the viewing angle of the viewer to a certain extent through the curved surface of the screen, and it still cannot automatically adjust the viewing angle (that is, the angle of this display with a curved screen structure needs to be adjusted by the user himself. change by hand), and the curvature of the curved screen is fixed and cannot be adjusted automatically. As the distance between the person and the screen changes, the best viewing angle will also be affected (that is, when the user moves indoors, the current Some display devices cannot realize the automatic tracking and identification of the display, adjust to the best viewing angle and curved surface radian to adapt to the change of the viewer's position), and then affect the user's viewing experience of the display
