Abstract
A method for making an OLED device, comprising: providing a plurality of subpixels of different colors, including at least three gamut-defining subpixels, each subpixel requiring an operating voltage which is based on the maximum current density required by that subpixel; selecting the display operating voltage to be equal to or greater than the maximum required subpixel operating voltage; and selecting the area of the subpixels to reduce the maximum required subpixel operating voltage, thereby reducing the display operating voltage so as to reduce power consumption in the device.

A method for making an OLED device, comprising:
- (a) providing a plurality of subpixels of different colors, including at least three gamut-defining subpixels, each subpixel requiring an operating voltage which is based on the maximum current density required by that subpixel;
- (b) selecting the display operating voltage to be equal to or greater than the maximum required subpixel operating voltage;
- and
- (c) selecting the area of the subpixels to reduce the maximum required subpixel operating voltage, thereby reducing the display operating voltage so as to reduce power consumption in the device.
A method for making an OLED device, comprising:
- (a) providing a plurality of subpixels of different colors, including at least three gamut-defining subpixels and one within-gamut subpixel, each subpixel requiring an operating voltage which is based on the maximum current density required by that subpixel;
- (b) selecting the display operating voltage to be equal to or greater than the maximum required subpixel operating voltage;
- and
- (c) selecting the area of the subpixels to reduce the maximum required subpixel operating voltage, thereby reducing the display operating voltage so as to reduce power consumption in the device.
An OLED device comprising,
- (a) a plurality of gamut-defining subpixels of different colors and at least one within-gamut subpixel;
- and
- (b) the areas of the gamut-defining subpixels being selected so that they have similar lifetimes, and the within-gamut subpixel having an area selected to reduce the maximum required subpixel operating voltage, thereby reducing the display operating voltage so as to reduce power consumption in the device.
