To read the turning of the bezel, the Galaxy Watch uses a different approach than the optical encoder of the Apple Watch. There are three hall sensors (Seiko Instruments) on the small PCB, at the same distance from each other as the grooves on the bezel. And every third groove has a small magnet inside.
  • To read the turning of the bezel, the Galaxy Watch uses a different approach than the optical encoder of the Apple Watch.

  • There are three hall sensors (Seiko Instruments) on the small PCB, at the same distance from each other as the grooves on the bezel.

  • And every third groove has a small magnet inside.

  • When the bezel is turned, two of the three sensors read a change in their magnetic field (either on/off or off/on). The third sensor does not read a change. With this method, it can be clearly determined in which direction the bezel is rotated.

Galaxy Watch 用了一个和 Apple Watch 使用的光学编码器不一样的装置来读取表圈的转动。

在小小的 PCB 上又三个霍尔传感器,和表圈上的凹槽一样每个之间的距离相同。

每三个凹槽里就有一个小磁铁。

当表圈倍转动,三个传感器中的两个救护读取到磁场的变化(开/关或关/开)。第三个传感器则不会读取到变化。在这种模式下,可以清楚的直到表圈转动的方向。
