A foldable AMOLED display capable of enduring very severe folding and environmental impact was obtained using symmetric panel stacking (SPS) with an innovative design of color filter structure. The display was subjected to in-situ folding cycle under an ambient test condition of 60° C/90% RH and no performance degradation was found for the display and the touch function during and after the test. In addition, 95% coverage of BT. 2020 color space was obtained without additional power consumption compared to that of the panel with NTSC color space.

A foldable active-matrix organic light-emitting diode display capable of enduring very severe folding and environmental impact was obtained using symmetric panel stacking with an innovative design of color filter structure. The display was subjected to in situ folding cycle under an ambient test condition of 60°C/90% relative humidity, and no performance degradation was found for the display and the touch function during and after the test. In addition, 95% coverage of BT.2020 color space was obtained without additional power consumption compared with that of the panel with National Television System Committee (NTSC) color space.

Quantum entanglement is a phenomenon available only at nanometer scale. In this paper, we show how quantum entanglement can be used to build cryptographic primitives such as oblivious transfer. In addition to studying the protocol itself, we also show how to realize some applications based on our proposal. These include typical e-Business applications such as contract signing, certified mail, simultaneous secret exchange, secure transaction and remote coin flip. Unlike classical oblivious transfer, the security of this protocol is based on physical laws, instead of any unproven mathematic conjecture. As a result, our proposal provides unconditional security for e-Business.
