Display Devices and Power Consumption
Recently I have got a new laptop at work the battery lasts up to 3 hours and it purely depends on the screen brightness I am using it. I use it in moderate brightness even when power is on. Today I was discussing some FS of mine and have connected it to the projector. It was working in a mode that display is only on the projector and I was using the application in full screen mode. And its almost 3 hours when I remembered that the power have to be plugged in. I immediately switched to normal mode to check out what percentage of battery is still left. To my surprise it showed it can last for another 2 hour 44 mins. I just couldn’t believe that. Later I realized it was due to my display on laptop was off.
The processor and the entire hardware consumed only 40% for more than 3 hours so 60% of the power is used up by the display in the normal mode. Hmmmmm Now do if we can have more power efficient display devices the same batteries can give a long back up and in turn less recharge which leads to low total power consumption and in saving energy:) so start finding one now.
So Moral of the story is… Keeping the brightness of the display device low is not only good for eyes but also will consume less power.
Save Energy! Save Earth!
He he too much isn’t it?
