  • Patent number: 10727874
    Abstract: A decoder performs forward error correction based on quasi-cyclic regular column-partition low density parity check codes. A method for designing the parity check matrix reduces the number of short-cycles of the matrix to increase performance. An adaptive quantization post-processing technique further improves performance by eliminating error floors associated with the decoding. A parallel decoder architecture performs iterative decoding using a parallel pipelined architecture.

  • Patent number: 10690808
    Abstract: Aspects disclosed herein relate to color filters for display devices, and more specifically to color filters for transmitting or reflecting and recycling colors of light in liquid crystal display devices. In one aspect, a metasurface is formed between two polarizers in an LCD device. In another aspect, a metasurface is formed on a white light guide of an LCD device. The metasurface is formed to transmit desired color(s) of light and to reflect undesired color(s) of light back into the light guide to be recycled and passed through the LCD device elsewhere. Using the color filter to recycle reflected colors of light increases the efficiency of the display device, such as the LCD device.
