  • Patent number: 7948164
    Abstract: An organic electro luminescence device includes: a display region and a non-display region defined in first and second substrates, sub-pixels defined in the display region; an array element including at least one TFT in the display region of the first substrate in each sub-pixel; a first electrode in an inner surface of the second substrate; a buffer in a predetermined region to partition an emission region of each sub-pixel on the first electrode, and an electrode separator on the buffer; an insulating layer in the emission region of each sub-pixel, and a spacer formed on the insulating layer; an organic electro luminescent layer in the emission region of each sub-pixel, the emission region including the insulating layer and the spacer; and a second electrode on the second substrate where the organic electro luminescent layer is formed.

  • Patent number: 7759854
    Abstract: A white-light electro-luminescent lamp having an adjustable spectral power distribution, including a first light-emitting element which emits light within each of three wavelength bands, 1) between 440 and 520 nm, 2) between 520 and 600 nm, and 3) between 600 and 680 nm. A second light-emitting element emits light within each of three wavelength bands, 1) between 440 and 520 nm, 2) between 520 and 600 nm, and 3) between 600 and 680 nm. A controller modulates the integrated spectral power of the light produced by the first and the second light-emitting elements such that the spectral power distribution of the light formed by combining the light produced by the modulated first and second light-emitting elements is substantially equal to a CIE standard daylight spectral power distribution for correlated color temperatures between 4000K-9500K.
