Abstract: A power reduced display includes a light source having an available space and configured to generate a backlight, a first display having multiple first pixels, wherein each first pixel is configured to selectively pass and block the backlight, a second display having multiple second pixels. The light source includes a first number of first packages each having a single light-emitting diode. The first number is a largest number of the first packages that fit in the available space of the light source. The first number of the first packages is configured to consume a first power to produce a particular luminance. A second number of second packages each having two light-emitting diodes alternatively fit in the available space and is configured to consume a second power to produce the particular luminance. The first number is greater than the second number. The first power is less than the second power.
