The invention discloses a displayer lifting control device and method. The control device comprises a control table body, a lifting machine, a displayer connected with the lifting machine, a driving component for driving the lifting machine, a control table surface, a camera component, a distance sensor and a controller, wherein the camera component is arranged on an outer frame in the vertical direction of a datum point of the displayer and used for shooting a user image; the distance sensor is used for detecting the distance between a user and the displayer; the controller enables the displayer to rise to penetrate through the control table surface. User eyes in the user image are identified, and horizontal coordinates and vertical coordinates of the user eyes in a preset image coordinate system are determined, a horizontal coordinate and a vertical coordinate of a central point of the user eyes are calculated, the vertical distance between the center of the user eyes and the camera component as well as the deflection angle between the center of the user eyes and the optical axis of the camera component are determined according to the calculated vertical coordinate, the calculated horizontal coordinate and the distance, and the driving component is controlled according to the deflection angle and the vertical distance so as to adjust the height and the direction of the displayer to enable the displayer to reach an expected position. With the adoption of the displayer lifting control device and method, the height and the direction of the displayer can be adjusted automatically.
