When I first entered the
internet in 2000, the first G-Shock I found was a DW-9005V. It looked black
on the picture, but it was actually dark blue when I bought it a short while
later. The coolest feature on this watch was the reversed display. A black
background with white digits.
meanwhile I now have several G-Shocks with a reversed display, but how does
The LCD's of a
G-Shock contain a liquid that can act as a solid. The compounds having this
ability are called Liquid Crystals. The most used liquid crystals are
cholesterol derivates. One of most important abilities of a liquid
crystal is that it is able to turn polarized light when put on an electric
potential. The twist of the light depends on the voltage.
On a day I
discovered a student, making his homework with a Casio calculator with a
reversed display. He told me that it was really quit simple. You only had to
open up your calculator and turn around the protection of the LCD screen.
