Abstract High‐quality backlit display puts forward urgent demand for color‐converting materials. Recently, metal halide perovskites (MHPs) with full spectral tunability, high photoluminescence quantum yields (PLQYs), and color purity have found potential application in wide‐color‐gamut display. Regrettably, naked MHPs suffer from long‐term instable issue cannot pass harsh stability tests. Herein, amorphous‐glass‐protected green/red CsPbX 3 dots (QDs) are prepared by elaborately optimizing...

Abstract Perovskite quantum dots (PeQDs) are seen as the credible alternative to traditional QDs ascolor converter in liquid crystal display (LCD). Unfortunately, PeQDs sufferfrom instability and color separation, prepared enhanced films(PQDFs) need protection of expensive barrier layers, which significantly increases price limits their application. Herein, large‐area yellow monolithic PQDF is fabricated with both green CsPbBr 3 red 1 I 2 encapsulated dual matrices inorganic glass...

Abstract Robust amorphous glass protected CsPbBr 3 (CsPbBr @glass) perovskite quantum dots (PeQDs) with ultra‐pure green emission and superior long‐term stability are highly desirable for developing wide‐color‐gamut liquid crystal displays. However, most of the reported @glass nanocomposites subject to low external efficiency (EQE). This work demonstrates that ZrO 2 additive has an “accumulation” effect on borosilicate network structure promote in situ nucleation/growth PeQDs inside rather...

A white LED backlit unit designed by coupling a CsPbBr 3 @glass@PDMS green film and Mn 4+ :K 2 SiF 6 red with home-made blue light guide panel endows liquid crystal display wide color gamut.

A comprehensive and comprehensible summary of existing deep neural networks (DNNs) helps practitioners understand the behaviour evolution DNNs, offers insights for architecture optimization, sheds light on working mechanisms DNNs. However, this is hard to obtain because complexity diversity DNN architectures. To address issue, we develop Genealogy, an interactive visualization tool, offer a visual representative DNNs their evolutionary relationships. Genealogy enables users learn from...

In this paper, two models of differential GPS, which are code GPS and real time kinematic (RTK), introduced, the effects multipath on RTK discussed. The data is collected by a Javad G80 receiver. By investigating stochastic characteristics data, calculated results show that principal causes influence positioning accuracy receiver noise.

Voice can be a powerful tool for use in humanoid teleoperation because it is the fundamental means of human communication. This paper puts forward system to control robot BHR-02 using voice.

Experiments are conducted confirm effectiveness novel technique.

Artificial intelligence has successfully integrated the frontier research in many fields, which is gradually mature. Among them, intelligent diagnosis of traditional Chinese medicine(TCM) entered initial stage. Tongue one methods clinical history collection TCM, as part "Four Diagnosis Traditional Medicine", playing an irreplaceable role diagnosing. Due to influence external environment such light and temperature, tongue lacks objective, quantitative standard evaluation application. Based on...

There has been much interest in improving gyroscope precision with quantum technology for realizing autonomous navigation. The laser light coherent state cannot reach higher under shot-noise limit (SNL) caused by vacuum zero energy fluctuation, which restricts the further improvement of optical precision. Quantum mechanics reckons that one unused port beam splitter (BS) is inputted vacuum, results while another gyroscope. In order to compress we design an experimental scheme, squeezed used...

Despite recent great progress on semantic segmentation, there still exist huge challenges in medical ultra-resolution image segmentation. The methods based multi-branch structure can make a good balance between computational burdens and segmentation accuracy. However, the fusion these require to be designed elaborately achieve desirable result, which leads model redundancy. In this paper, we propose Meta Segmentation Network (MSN) solve challenging problem. With help of meta-learning, module...
