Claims12
A display apparatus, comprising:
- a display panel;
- a needle module on the display panel, the needle module including an indicator needle rotatable with respect to a rotation axis;
- and
- a driving module to rotate the indicator needle via magnetic force, the indicator needle being rotatable by the magnetic force,
- wherein:
- the display panel is between the needle module and the driving module, a region of the display panel overlapping the rotation axis of the indicator needle including no holes,
- the needle module includes a first rotating part, a first magnet in the first rotating part, a second rotating part, and a second magnet in the second rotating part, and the indicator needle includes first and second needles which rotate in accordance with rotation of the first and second rotating parts, respectively,
- driving module on a surface of the display panel includes a first rotating driving part, a first driving magnet in the first rotating driving part, a second rotating driving part, and a second driving magnet in the second rotating driving part,
- the first magnet has a first-pole and a second-pole, and the second magnet has a first-pole and a second-pole,
- the first driving magnet has a first-pole and a second-pole, and the second driving magnet has a first-pole and a second-pole, and
- a net attractive force is applied between the first-pole of the first magnet and the second-pole of the first driving magnet, a net attractive force is applied between the first-pole of the second magnet and the second-pole of the second driving magnet, such that the first rotating part rotates when the first rotating driving part rotates, and the second rotating part rotates when the second rotating driving part rotates.
