Abstract
A display device includes a casing, a display unit, an optical sensing unit, a driving unit and a processing unit. The processing unit controls the display unit to display a predetermined pattern corresponding to a predetermined range. The predetermined pattern includes a target area. The target area is adjacent to a target position and corresponds to a driving parameter of the driving unit. When the optical sensing unit is located within the target area, the driving unit drives the optical sensing unit to move to the target position by a predetermined manner. When the optical sensing unit is located beyond the target area, the driving unit drives the optical sensing unit to move towards the target position. When the optical sensing unit moves to a boundary of the target area, the driving unit drives the optical sensing unit to move to the target position by the driving parameter.
