Description

Adaptive Display

The present disclosure relates to a display device, and in particular to an adaptive display device.

Conventionally, a display device used in a vehicle is assembled on a seat, and the screen and the bracket are relatively rotatably connected around a single axis. When the angle of the screen needs to be changed, the angle of the screen needs to be adjusted manually. However, this adjustment method requires additional manual adjustments. When encountering bumpy road conditions, frequent manual adjustments are required, which is quite inconvenient.

Therefore, the present disclosure proposes an adaptive display device, which can solve the problem of artificially adjusting the display device.

An embodiment of the disclosure provides an adaptive display device suitable for a seat. The adaptive display device includes a screen, a frame, an orientation sensor, a first motor and a controller. The bracket includes a first rod, a second rod and a third rod. The first rod is connected to the screen. The second rod is rotatably connected with the first rod around a first axis. The third rod is fixed on the seat, and the third rod is rotatably connected with the second rod around a second axis. The orientation sensor is arranged on the first bar or the screen, and is used for sensing an inclination angle of the screen. The first motor connects the first rod with the second rod, or connects the second rod with the third rod. The controller is electrically connected to the orientation sensor and the first motor, and is used to drive the first motor according to the tilt angle, so as to drive the bracket to move and keep the screen at a preset orientation.

In this way, the adaptive display device can automatically detect the current orientation of the screen, and accordingly automatically adjust the screen to maintain the default orientation.

In order to have a better understanding of the above and other aspects of the present disclosure, the following specific embodiments are described in detail in conjunction with the attached drawings as follows:
