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： In various embodiments, the invention is directed to aperture mask deposition techniques for use in creating integrated circuits or integrated circuit elements. In other embodiments, the invention is directed to different apparatuses that facilitate the deposition techniques. The techniques generally involve sequentially depositing material through a number of aperture masks formed with patterns that define layers or portions of various layers of a circuit. In this manner, circuits can be created using aperture mask deposition techniques, without requiring any etching or photolithography, which is particularly useful when organic semiconductors are involved. The techniques can be useful in creating circuit elements for electronic displays, low-cost integrated circuits such as radio frequency identification (RFID) circuits, and other circuits.

摘要： A method for making full color display panel pixels is described. One aspect of the method relates to simultaneously depositing red, green, and blue dopants such that the blue dopant is dispersed in at least one non-blue subpixel. Another aspect of the method relates to using an integrated or removable mask to deposit components. In an angled evaporation method, the mask can correct for parallax.

摘要： Light emitting systems are disclosed. The light emitting system includes an LED that emits light at a first wavelength. A primary portion of the emitted first wavelength light exits the LED from a top surface of the LED that has a minimum lateral dimension Wmin. The remaining portion of the emitted first wavelength light exits the LED from one or more sides of the LED that has a maximum edge thickness Tmax (122, 124). The ratio Wmin/Tmax is at least 30. The ligth emitting system further includes a re-emitting semiconductor construction that includes a semiconductor potential well. The re-emitting semiconductor construction receives the first wavelength light that exits the LED from the top surface and converts at least a portion of the received light to light of a second wavelength. The integrated emission intensity of all light at the second wavelength that exit the light emitting system is at least 4 times the integrated emission intensity of all light at the first wavelength that exit the light emitting system.

摘要： An electroluminescent device emits light at a pump wavelength. A first photoluminescent element covers first and second regions of the electroluminescent device and converts at least some of the pump light from the first region of the electroluminescent device to light at a first wavelength. A second photoluminescent element covers the second region of the electroluminescent device without covering the first region of the electroluminescent device and converts at least some of the light of the pump wavelength to light at a second wavelength different from the first wavelength. In some embodiments the first and second photoluminescent elements convert substantially all of the pump light incident from the first and second regions of the electroluminescent device respectively. An etch-stop layer may separate the first and second photoluminescent elements.
