Étape 5
The chip on the left is used to store data, whereas the chip on the right side acts just like a projector. We can see that there are thousands of dots arranged here. The infrared light is emitted from here. Since necessary power supply is needed for chip on the right side to work normally, once water damaged, circuits here are most likely to get short. Which can also result in Face ID not working.
Internal Structure Of The Dot Projector
  • The chip on the left is used to store data, whereas the chip on the right side acts just like a projector. We can see that there are thousands of dots arranged here. The infrared light is emitted from here.

  • Since necessary power supply is needed for chip on the right side to work normally, once water damaged, circuits here are most likely to get short. Which can also result in Face ID not working.

  • And please be noted that the chip is exposed without black adhesive seal. So it can be easily damaged once water-damaged or dropped. What’s more, it also can not be restored once damaged.

左边的芯片用于存储数据,而右边的芯片就像一个投影仪。 我们可以看到,这里排列了数千个点。 红外线从这里发出。

由于右侧芯片正常工作需要必要的电源,一旦进水,这里的电路很容易短路。 这也可能导致 Face ID 无法正常工作。

并且请注意,芯片是裸露的,没有黑色胶封。 因此,一旦进水或跌落,它很容易损坏。 更重要的是,它一旦损坏也无法恢复。
