In the present embodiment, the input unit 4 is a button. The present invention is not limited thereto. The input unit 4 can be disposed on the base 6 or on the keyboard on the base 6. Any one button (not shown) is provided to provide the user user with the request r for adjusting the elevation angle by pressing the input unit 4, and the adjustment angle of the display plane 71 is adjusted. When the user user inputs the request r for adjusting the elevation angle from the input unit 4 and issues the second control signal S3, the processing unit 3 generates the fifth control signal S5 to the detecting unit 相对 corresponding to the third control signal S3 to start the detection. The measuring unit detects the two eye positions of the user user in the manner described above. When the user user inputs the request R for adjusting the elevation angle from the input unit 4, and the third control signal S3 B is issued, the processing unit 3 generates the fourth control signal S4 corresponding to the third control signal and is received by the rotating unit 2. To adjust the elevation angle of the display plane 71 of the display 7 to the initial elevation angle 0, as shown in FIG. In other embodiments, the processing unit 3 will again determine the initial elevation angle Θ and the money elevation angle θ based on the results obtained by the following calculation formula. Yc =lcsin0 zc = lc cos6> where L is the height of the center of the curtain; s = {ye-ycf +(ze-zcf +ic if / differs from the number of g in the limit number) The initial elevation angle 201024958 相 is similar to the rectilinear elevation angle 0 ', which represents the user's user's second eye line of sight l is perpendicular to the display screen plane 71 of the display 7, and does not need to adjust the display screen plane 71 elevation angle of the display 7; otherwise, the processing unit 3 issues the first The control signal S2 is controlled so that the rotation unit 2 adjusts the elevation angle of the display screen plane 71 of the display 7 to the elevation angle 0. However, in other embodiments, the electronic device 100 may further have the sensing unit 5. The sensing unit 5 may be grouped. When the external obstructing object (not shown) which may hinder the rotation of the display 7 is sensed on the display screen plane 71 of the display 7, the sixth control signal S6 may be issued to the processing unit 3. At this time, the processing is performed. The unit 3 generates the seventh control signal S7 corresponding to the sixth control signal S6 to the rotating unit 2, and stops or further adjusts the elevation angle of the display screen plane 71 of the display 7 to prevent the display 7 from colliding with the external obstructing object.
