Light-emitting diode displays with low latency and related methods

Patent published on the 2026-10-15 in US under Ref US20260323801 by CREELED INC [US] (Hussell Christopher P [us])

Abstract: [0000] Light-emitting diode (LED) packages and, more particularly, LED displays with low latency and related methods are disclosed. LED displays and related methods include reverse-pixel addressing that involves arranging data stream segments in reverse order so that an LED package that is farthest away in a serial string receives its data segment precedently or concurrently with that of an LED package positioned at the beginning of the serial string. LED packages form LED pixels of an array whe[...]


Our summary: LED displays utilize low latency techniques through reverse-pixel addressing. This method allows data segments to be arranged in reverse order for efficient data loading. The result is that all LED pixels receive their data simultaneously, enabling quick frame advancement.

Theory of spin qubits and the path to scalability

Published on 2026-08-21 by Z M McIntyre, Abhikbrata Sarkar and Daniel Loss @IOP SCIENCE

Abstract: Spin qubits have emerged as a leading platform for quantum information processing due to their long coherence times, small footprint, and compatibility with the existing semiconductor industry. We first provide an introduction to the different qubit implementations currently being investigated, including single electron-spin qubits, hole-spin qubits, donor qubits, and multispin encodings. We discuss how the confinement and strain present in semiconductor heterostructures produce addressable leve[...]
