    摘要: An organic light emitting diode includes a display substrate assembly including an organic light emitting element; an encapsulation substrate assembly (210) disposed on the display substrate assembly (110) with a space therebetween and sealed with the display substrate assembly in a vacuum-tight manner; and a filling agent (300) filling the space between the display substrate assembly (110) and the encapsulation substrate assembly (210). The filling agent is adapted to selectively absorb external light entering through the encapsulation substrate assembly (210) and incident on the organic light emitting element as a function of wavelength in a wavelength band of the external light to control transmittance.

    摘要: A composition comprising a polymer backbone and at least one side group, wherein the side group comprises a benzene ring-based chromophore comprising a ketone at the 1-position, a substituted or unsubstituted amino group at the 2-position, and an oxygen atom at the 3-position of the benzene ring having the following formula: wherein R1 is H, an alkyl group, or comprises an amino acid moiety or derivative thereof; R2 and R3 are individually H, alkyl, or any moiety with a vinyl functionality; R4 is an alkyl group, any moiety with a vinyl functionality, a counterpart alkyl²ne group, or a sugar moiety; and X is an optional electron-donating group linked to the benzene ring at the 4, 5, or 6 position. The chromophore is a kynurenine-based compound. Methods of making and using the composition are also provided. The composition can be used in an ophthalmic lens or device for protecting the retina by blocking UV rays and filtering violet rays.
