Approaches to robust encoding and decoding of escape-coded pixels in a palette mode are described.

Methods of encoding and decoding for video data are described in which multi-level significance maps are used in the encoding and decoding processes. The significant-coefficient flags that form the significance map are grouped into contiguous groups, and a significant-coefficient-group flag signifies for each group whether that group contains no non-zero significant-coefficient flags. If there are no non-zero significant-coefficient flags in the group, then the significant-coefficient-group flag is set to zero. The set of significant-coefficient-group flags is encoded in the bitstream. Any significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is non-zero are encoded in the bitstream, whereas significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is zero are not encoded in the bitstream. |

Making semiconductor devices by stacking strata of micro LEDs
A stack of strata containing LEDs is fabricated by repeatedly bonding unpatterned epitaxial structures. Because the epitaxial structures are unpatterned (e.g., not patterned into individual micro LEDs), requirements on alignment are significantly relaxed. One example is an integrated multi-color LED display panel, in which arrays of micro LEDs are integrated with corresponding driver circuitry. Multiple strata of micro LEDs are stacked on top of a base substrate that includes the driver circuitry. In this process, each stratum is fabricated as follows. An unpatterned epitaxial structure is bonded on top of the existing device. The epitaxial structure is then patterned to form micro LEDs. The stratum is filled and planarized to allow the unpatterned epitaxial structure of the next stratum to be bonded. This is repeated to build up the stack of strata. |
