Display equipment and method for automatically regulating display direction

Abstract

The invention provides a display device capable of automatically adjusting display direction, which comprises a display screen, a rotary mechanism and a fixing stand. The display screen connected with the fixing stand through the rotary mechanism is provided with an optimum viewing angle. The rotary mechanism is used for rotating the display screen corresponding to the fixing stand. The display device further comprises an automatic adjusting system which comprises an image acquiring unit, a detecting unit, an analyzing unit and a rotation control unit, wherein the image acquiring unit is used to shoot image data of scenes at the front of the display screen, the detecting unit is used to detect position of human eyes in the scene image data, the analyzing unit is used to obtain an needed angle to be adjusted for the display screen according to the position of human eyes and the optimum viewing angle of the display screen, the rotation control unit is used to drive the rotary mechanism to adjust the direction of the display screen according to the needed angle to be adjusted for the display screen obtained in the analyzing unit, and enables human eyes to be arranged in the optimum viewing angle of the display screen. The display device further provides an automatic adjusting method for the display direction.

Description

technical field [0001] The invention relates to a display device, in particular to a display device and a method for automatically adjusting the display direction. Background technique [0002] The viewing angle refers to the angle at which the user can clearly observe all the content on the screen from different directions, which is a very important parameter of the LCD display. The viewing angle is caused by the refraction and reflection of the light source that provides the LCD display screen, the output direction changes, and a certain angle is generated. When viewing beyond this angle, color distortion will occur. For example: if you sit in front of the LCD and can see the image clearly at 70 degrees on the left and right sides, then the horizontal viewing angle of the display screen is 140 degrees, and the same is true for the vertical viewing angle. However, when you look at the display screen beyond this angle You may not be able to see clearly or the color of the i...

Problems solved by technology

For example: if you sit in front of the LCD and can see the image clearly at 70 degrees on the left and right sides, then the horizontal viewing angle of the display screen is 140 degrees, and the same is true for the vertical viewing angle. However, when you look at the display screen beyond this angle You may not be able to see clearly or the color of the image you see is abnormal

[0003] For the existing LCD display screens, there is almost a viewing angle problem. When viewing the display screen image beyond the viewing angle, in order to make the image clearer, the user must manually adjust the angle of the LCD display screen up and down or left and right to achieve Optimal Viewing, Extremely Inconvenient
