摘要:
A light output device and manufacturing method in which an array of LEDs (34) is embedded in an encapsulation layer (32). An array of cavities (30) (or regions of different refractive index) is formed in the encapsulation layer (32). The cavities/regions (30) have a density or size that is dependent on their proximity to the light emitting diode (34) locations, in order to reduce hot spots (local high light intensity areas) and thereby render the light output more uniform over the area of the device.

摘要:
A lighting device has an array of light emitting diodes (LEDs), an adhesion layer having portions with photo-activated electrical conductivity over the LEDs, and electrically charged scattering particles adhered by electrostatic attraction to the adhesion layer portions, thereby forming scattering regions that are self-aligned to the light emitting diodes. A method for manufacturing the lighting device includes photo-activating the adhesion layer using light output from the light emitting diodes to locally vary the conductivity of the adhesion layer; and attaching electrically charged scattering particles to the adhesion layer by electrostatic attraction.

A data processing method and system provided in this disclosure perform decoding spectrum modulation on the compressed data by using a decoding convolution kernel and perform a boundary adjustment, where the decoding convolution kernel corresponds to an encoding convolution kernel in data compression, so that an amplitude of decompressed data in a low-frequency to intermediate-frequency region is approximately equal to, or greater than or equal to an amplitude of an original frame, and the boundary adjustment can effectively eliminate a ringing effect after the decoding spectrum modulation and make the decompressed data clearer. The method and system can improve data compression efficiency, and improve transmission efficiency, while improving definition of the decompressed data.
摘要:
A data processing method and system provided in this disclosure can perform encoding spectrum modulation on original data, so that an amplitude of an original frame in a selected region is smoothly decreased, thereby reducing an amount of data information and improving data compression efficiency; during decompressing compressed data, decoding spectrum modulation is performed on the compressed data by using parameters corresponding to the encoding spectrum modulation, subtraction is performed between the compressed data and the data that has undergone the decoding spectrum modulation to obtain boundary information, and the boundary information is then superimposed on the compressed data, so that an amplitude of decompressed data is restored or enhanced in the selected region. The decoding spectrum modulation may effectively avoid a ringing effect. The method and system can improve the data compression efficiency, and improve transmission efficiency, while improving definition of the decompressed data.
摘要:
The data processing method and system provided in the present specification may use an encoding convolution kernel to perform an encoding spectrum-adjustment on an original frame in original data when compressing the original data, so that the amplitude of the intermediate-frequency to high-frequency region in the original frame may be smoothly reduced, thereby reducing the data information in the original frame and improve the encoding efficiency. Thus, the compressed data volume is reduced. When the method and system are employed to decompress a compressed frame, a decoding convolution kernel may be used to perform a decoding spectrum-adjustment on the compressed frame, where the decoding convolution kernel corresponds to the encoding convolution kernel, so as to restore the data in the compressed frame and obtain a decompressed frame. The method and system may improve data compression efficiency and transmission efficiency.
