  • Patent number: 11602057
    Abstract: A display device including a display panel, a shaft, a correcting sensor and a driving module is provided. The display panel has a display surface. The shaft has an axial end and a correcting end opposite the axial end. The correcting sensor is disposed on the correcting end. When the shaft is rotated relative to the axial end, the correcting sensor is moved to a second position from a first position and faces the display surface at the second position. The driving module is configured to translate the shaft when the correcting sensor is at the second position, such that the correcting sensor can be moved to a detecting position from the second position, wherein the distance of the second position relative to the display surface is greater than the distance of the detecting position relative to the display surface.

  • Publication number: 20080029668
    Abstract: A positioning device includes a fixing component including an arc slot with a first end, a positioning plate connected to the fixing component in a rotatable manner relative to the fixing component, and a first adjusting component positioned on the positioning plate in a slidable manner inside the arc slot. The first adjusting component includes a first-radius section and a second-radius section. A cross-sectional area of the first-radius section is larger than a cross-sectional area of the second-radius section. The first adjusting component can be positioned in a first location or a second location selectively. When the first adjusting component is positioned in the first location, the first-radius section contacts with the first end. When the first adjusting component is positioned in the second location, the second-radius section contacts with the first end.
