Embodiment 1

[0035] figure 1 It shows the implementation flow chart of the method for automatically adjusting the orientation of the display device provided by Embodiment 1 of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0036] In step S101, the infrared signal corresponding to the body temperature of the viewer within the viewing angle range of the display device is collected, and a first infrared signal with a preset intensity is separated from the collected infrared signal.

[0037] In nature, all objects with a temperature higher than absolute zero are constantly emitting infrared radiation energy (that is, infrared signals) to the surrounding space. The normal temperature distribution of the human body has certain stability and symmetry. figure 2 It shows the distribution of the infrared signal radiated by the body temperature of the human body under different ...

Abstract

The invention provides automatic direction adjustment method and system for a display device as well as a display device, belonging to the technical field of display. The method comprises the following steps of: collecting infrared signals corresponding to the body temperature of an observer within the viewing angle of the display device, separating a first infrared signal with preset intensity from the collected infrared signals, determining the coordinates of the target corresponding to the first infrared signal in a preset plane coordinate system, determining one or more graphs formed by the object corresponding to the first infrared signal in the plane coordinate system, determining the transverse rotation direction and the longitudinal rotation direction of the display device according to the central position of each graph, and rotating the display device according to the transverse rotation direction and the longitudinal rotation direction. Therefore, the direction of the display device is automatically adjusted according to the position of the observer within the viewing angle of the display device, the problem that the direction of the traditional intelligent television display device can not be automatically adjusted to accommodate the movement of user position or watching by multiple users is solved, and the intelligence degree of the display device is increased.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a method, a system and a display device for automatically adjusting the orientation of a display device. Background technique [0002] With the continuous advancement of science and technology, users' demand for personalized information continues to increase. Smart TV has begun to become the third information access terminal after computers and mobile phones. It can realize network search, network news, network video calls, network Various application services such as TV (IP TV), video on demand and digital music. [0003] However, since the display device of the smart TV has its own viewing angle (viewing angle), users at different locations have different viewing effects. When the user moves the position while watching TV, or when many people watch TV programs, the display device of the smart TV cannot automatically adjust its orientation to adapt to the position ...
