摘要： Light emitting systems are disclosed. The light emitting system emits an output light that has a first color. The light emitting system includes a first electroluminescent device that emits light at a first wavelength in response to a first signal. The first wavelength is substantially independent of the first signal. The intensity of the emitted first wavelength light is substantially proportional to the first signal. The light emitting system further includes a first luminescent element that includes a second electroluminescent device and a first light converting layer. The second electroluminescent device emits light at a second wavelength in response to a second signal. The first light converting layer includes a semiconductor potential well and converts at least a portion of light at the second wavelength to light at a third wavelength that is longer than the second wavelength. The light emitting system combines light at the first wavelength with light at the third wavelength to form the output light at the first color. When one of the first and second signals changes from about 50% of a maximum rating of the signal to about 100% of the maximum rating, but the ratio of the first signal to the second signal remains substantially unchanged, the first color of the output light remains substantially unchanged.

摘要： A system for generating and providing a simulated image. Based upon a source image and first parameters for a first display device, the system generates and displays a simulated image on second display device having second parameters. The first parameters are different from the second parameters, and the simulated image displayed on the second display device provides a visual indication of how the source image would appear when displayed on the first display device. The parameters can include a resolution in pixels per inch and a fill factor for the display device. The system can also be used to provide a visual indication of how the source image would appear when displayed on the second display device under varying lighting conditions and viewing angles.
