New iPad’s Quality Color Consumes Up to 30% of Tablet’s Power

The third-generation iPad boasts of a 44 percent enhancement in color saturation over its predecessor. This comes, however, at the price of increasing the tablet’s power consumption for 20 to 30 percent.

Dot Color has discovered that this improvement in image and text quality is due to the advanced red, blue, and green color filters on the iPad’s famous Retina Display. These filters enabled Apple to maintain a similar brightness with the older iPad models while enhancing the vividness of the colors.

On LCD displays, a common issue is unwanted leakage of light. This causes the device to inaccurately reproduce colors and decrease saturation, resulting in dull colors. There are two solutions to this problem. The first is to improve the backlight LEDs, and the second is to install high quality color filters.

Both solutions work to create the purest red, green, and blue representations possible. All three are eventually combined to create the entire spectrum of colors available on the display.

Apple chose to enhance the filters, which also caused the device to be more power-hungry than its predecessor since these filters block unwanted light better than less-efficient filters.

This new technology is surmised to be one of the reasons why the new iPad has a 42.5-watt-hour battery.
