How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 1 µW for the electrical draw of a digital wristwatch LCD; the recorded range is 0.1 µW–10 µW.
- The electrical draw of a digital wristwatch LCD: This is a representative comparison value; individual specimens or conditions can vary.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
Power is the rate of energy transfer or use, not the total energy.
