摘要： A pixelated light emitting diode (LED) and a method for pixelating an LED are described. The pixelated LED includes two or more monolithically integrated electroluminescent elements disposed adjacent each other on a substrate, wherein at least a portion of each electroluminescent element immediately adjacent the substrate includes an inverted truncated pyramidal shape. The method for pixelating an LED includes selectively removing material from the major surface of an LED to a depth below the emissive region, thereby forming an array of inverted truncated pyramid shapes. The efficiency of the pixelated LEDs can be improved by incorporating the truncated pyramidal shape. Additionally, the crosstalk between adjacent LED pixels can be reduced by incorporating the truncated pyramidal shape.

摘要： A front reflector (610) in a hollow cavity backlight (600) has asymmetrically reflective properties due to a film of alternating polymer layers recycling the light. The backlight addresses the need for thinner, lighter, large-area devices with fewer components but defined output polarisation and adequate viewing angles. A uniform light distribution in the guide and a directed output light (662) distribution are necessary. A front reflector (610) has a partial reflectivity for one polarisation state (662a) and a high reflectivity for the orthogonal state (666), wherein the partial reflectivities of the desired output polarisation state differ according to according to incident s- and p- polarisation states. There is also an asymmetric front reflector reflecting all light of one incidence angle distribution but partially reflecting & transmitting other light. A conversion structure in the cavity converts light of the first distribution into the second distribution. Application: displays or general lighting.

摘要： An imager pixel array capable of separating and detecting the spectral components of an incident light without the use of a color filter array. The imager pixel array employs a grating layer which allows one or more spectral components of incident light to be transmitted therethrough, but diffracts other spectral components of the incident light. Both the transmitted and diffracted spectral components can be sensed by photosensors in the imager pixel array and used in subsequent data processing, thereby improving the quantum efficiency of the imager device. The grating layer can be formed of first and second materials each having a refractive index which are substantially the same at a predetermined wavelength.
