    • Disclosed are a method for driving a glasses-type stereoscopic display preventing visual fatigue and refractive index-variable shutter glasses. The method includes generating a plurality of left-eye viewing point images and a plurality of right-eye viewing point images. The plurality of left-eye viewing point images and right-eye viewing point images have viewing points different from each other. An initial left-eye viewing point image and a subsequent left-eye viewing point image of the plurality of left-eye viewing point images are output, and an initial right-eye viewing point image and a subsequent right-eye viewing point image of the plurality of right-eye viewing point images are output. Each of the plurality of left-eye viewing point images and right-eye viewing point images is inputted into a single pupil. The glasses include a refractive index control unit to control a strength of an electric field to vary a refractive index of the glasses.

    • Disclosed are a hinge assembly and a mobile device having the hinge assembly. In the mobile device, a rotation portion 14 slides and rotates on a base portion 10, so as to be inclined to the base portion 10. For this reason, the rotation portion 14 is connected to the base portion by means of the hinge assembly 20 so as to slide and rotate on the base portion 10. The rotation portion 14 slides on the base portion by a predetermined distance, and then rotates to be inclined at a desired angle with respect to the base portion 10. The rotation portion 14 easily rotates with respect to the base portion of the mobile device, so that the status of the mobile device can be easily converted. Further, when the status of the mobile device is converted, the front, rear, left and right of a display screen is not changed. As a result, the mobile device should not have a structure of changing a display direction of the display screen. Further, there is an advantage in that an electric connection between the base portion and the rotation portion by means of a connection link mechanism can be stably achieved.
    • 公开了具有铰链组件的铰链组件和移动装置。 在移动装置中,旋转部14在基部10上滑动旋转,从而与基部10倾斜。因此,旋转部14通过铰链组件20与基部连接 以便在基部10上滑动旋转。旋转部分14在基部上滑动预定距离,然后旋转以相对于基部10倾斜所需的角度。旋转部分14容易旋转 相对于移动设备的基础部分,使得可以容易地转换移动设备的状态。 此外,当移动设备的状态被转换时,显示屏幕的前,后,左,右不改变。 结果,移动设备不应该具有改变显示屏的显示方向的结构。 另外,通过连接机构,能够稳定地实现基部与旋转部之间的电连接。
