Claim:
1. A display device comprising: a display main body; a base for supporting the display main body; at least three voice receiving devices, configured to receive voice information from outside of the display device, wherein the voice receiving devices are arranged on the display main body and/or on the base, and projections, on a horizontal plane, of the voice receiving devices are not located in a same straight line; a control device, configured for recording a time point when the control device receives the voice information inputted by each of the voice receiving devices, calculating time difference between time points when any two of the voice receiving devices receive the voice information, determining a location where the voice information is emitted according to the time difference and sending out a rotating instruction; and a rotation device, configured for rotating the display main body according to the rotating instruction; wherein: the control device is configured to calculate an angle θ between a connecting line, which is from a center point on a display surface of the display main body to the location where the voice information is emitted, and a line that passes the center point and extends in a horizontal direction on the display surface, and to determine whether the angle θ falls within an optimal viewing angle range; and if the angle θ is not within the optimal viewing angle range, the control device is configured to control the rotation device to rotate the display main body until the angle θ is rotated into the optimal viewing angle range.
