    • A scanning beam display system includes an optical module (10; 110), an image control module (320), and a display screen (1; 101) on which optical beams (12; 120) are scanned. The optical module (10; 110) includes a vertical adjuster (340) placed in the optical paths of the beams (12; 120) to control and adjust positions of the optical beams (12; 120) along a generally vertical direction on the display screen (1; 101), and a control unit (380) configured to receive control instructions for the vertical adjuster (340) and to control the vertical adjuster (340) to be at one of a predetermined number of orientations to place the scanning optical beams (12; 120) at a corresponding distinct position on the display screen (1; 101). The control unit (380) is further configured to apply an adjustment offset to each orientation of the vertical adjuster (340) such that each immediately vertically adjacent pair of beam footprints (412) projected on the display screen (1; 101) resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.
    • 扫描光束显示系统包括其上扫描光束(12; 120)的光学模块(10; 110),图像控制模块(320)和显示屏幕(1; 101)。 光学模块(10; 110)包括放置在光束(12; 120)的光路中的垂直调节器(340),以在显示器上沿大致垂直方向控制和调节光束(12; 120)的位置 (1; 101);以及控制单元(380),其被配置为接收用于所述垂直调节器(340)的控制指令并且控制所述垂直调节器(340)处于预定数量的方位中的一个以将所述扫描光学 在所述显示屏(1; 101)上的相应不同位置处的光束(12; 120)。 控制单元(380)进一步被配置为向垂直调节器(340)的每个方位施加调节偏移量,使得投影在显示屏(1; 101)上的每个直接垂直相邻的光束覆盖区(412) 多个位置具有大于第一阈值的垂直重叠。
