Abstract
The degradation of less than all of the pixels of a polymer display may be monitored and the uniformity of the display may be adjusted by either overdriving a given pixel or reducing the light output of other pixels in the display. In this way, the display's lifetime may be maximized without incurring pixel non-uniformity. In addition, the characteristics of the display may be monitored over time in order to provide the user with an early warning of imminent display failure.
Claims30
A method of controlling a polymer display comprising:
- identifying pixels in said display having reduced output light intensity relative to other pixels in said display;
- and
- adjusting the output light intensity of said display in view of the presence of pixels having reduced output light intensity.
An article comprising a medium for storing instructions that cause a processor-based system to:
- identify pixels in a polymer display having reduced output light intensity relative to other pixels in said display;
- and
- adjust the output light intensity of the polymer display in view of the presence of pixels having reduced output light intensity.
A method of controlling a polymer display comprising:
- monitoring a value indicative of imminent end of life;
- and
- when said value indicates imminent end of life, indicating to the user that the display is failing.
An article comprising a medium for storing instructions that cause a processor-based system to:
- monitor a value indicative of the imminent end of life of a polymer display;
- and
- when said value indicates imminent end of life, indicate to the user that the display is failing.
A polymer display comprising:
- a plurality of light emitting polymer elements;
- drive circuitry adapted to selectively operate said pixel elements in either a light emitting mode or a light detecting mode;
- and
- a device adapted to cause one of said elements to emit light and at least one of said other elements to detect the light emitted by said one element.
