Abstract
Organic light emitting display (OLED) devices and methods of rendering image of an OLED device. A pixel of the OLED device includes a first sub-pixel corresponding to a first color, comprising a first pixel electrode and a second sub-pixel corresponding to a second color, comprising a second pixel electrode. A portion of the second pixel electrode is operatively associated with a portion of the first sub-pixel, such that activation of second pixel electrode activates both the first sub-pixel and said portion of the first sub-pixel independent of activation of the first pixel electrode.
Claims17
A pixel structure for a color display device, comprising:
- a first sub-pixel corresponding to a first color, comprising a first pixel electrode;
- and
- a second sub-pixel corresponding to a second color, comprising a second pixel electrode, wherein a portion of the second pixel electrode is operatively associated with a portion of the first sub-pixel, such that activation of second pixel electrode activates both the second sub-pixel and said portion of the first sub-pixel independent of separate activation of the first pixel electrode.
A pixel structure for a color display device, comprising:
- a plurality of color filters, each corresponding to a different color;
- and
- a plurality of light emitting elements, each associated and positioned with respect to a color filter to render a colored light corresponding to the associated color filter when the associated light emitting element is activated, wherein a portion of at least one light emitting element is positioned with respect to at least another color filter, such that activation of said at least one light emitting element renders colored light corresponding to at least two color filters.
A pixel structure for a color display device, comprising:
- a substrate;
- a plurality of sub-pixel electrodes supported on the substrate;
- a plurality of light emitting elements supported on the substrate, each associated and positioned with respect to a sub-pixel electrode to render a white light;
- a plurality of color filters supported on the substrate, each corresponding to a different color and associated with a light emitting element, wherein a portion of at least one light emitting element is positioned operatively with respect to at least another color filter, such that activation of said at least one light emitting element renders colored light corresponding to at least two color filters.
A method of rendering color of a pixel in a display device, comprising:
- defining a first sub-pixel corresponding to a first color;
- defining a second sub-pixel corresponding to a second color;
- activating the first sub-pixel to render a first color;
- and
- activating the second sub-pixel to render a second color and a portion of the first sub-pixel to render the first color independent of separate activation of the first sub-pixel.
