Image displayed is primarily a function of the user’s color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen.
Roberson et al, 2002.
Just have a look at the Demo to see how it looks:
How to Use
Using this script is damn simple just place following script tag anywhere in the page. It would be good if you place this script just before </body>
There are two configurable parameters:
- time : This is the amount of idle time before which the screen turn black. The time is in number of seconds and its value should be greater than 10.
- credit : This is boolean field to show / hide credits in Black Screen. Values could be 1 or 0
Hope this script saves some of the valuable world energy.
