Why are digital cameras different from mobile phones? Why doesn't the screen of a digital camera make the pixels higher?

Because digital cameras don't need screens with too high pixels.

The reason for this is the following：

1. High pixels lead to high cost, and finally users need to pay the bill.

2. Pixels are too expensive, who is willing to sacrifice standby time to improve pixels?

3. A camera usually doesn't need to look at the screen, but only at the viewfinder, while mobile phone photography depends on the screen.
