Flexible inorganic electroluminescent devices exhibit high luminous efficiency, rapid response, low production costs and stable luminescence. These devices can be employed for flexible displays, intelligent sensing and other functions, making them promising candidates for applications in smartphones, electronic skin and smart wearables. Textile materials, with their flexibility, wearability, and well-established processing techniques, serve as excellent substrates for these flexible electroluminescent devices. In recent years, the structural design of flexible inorganic electroluminescent devices has matured significantly, driving research and development efforts across a wide range of applications, particularly in wearable electronics, displays and bionic robots. Electroluminescence primarily arises when a current passes through a substance, causing it to emit light under a strong electric field. Two main types of electroluminescence exist: injection electroluminescence and intrinsic electroluminescence. In the case of injection electroluminescence (also known as low-field electroluminescence), electrons and holes are directly injected from the electrodes into the crystal. When these charge carriers recombine within the crystal, excess energy is released in the form of light. Intrinsic electroluminescence (or high-field electroluminescence) is akin to an in vivo luminescence effect. In inorganic electroluminescent materials, electrons gain energy and collide with and excite luminescent centers under high electric fields. Consequently, the excited electrons in the luminescent centers transition to lower energy states, emitting light. Currently, the most widely used inorganic electroluminescent materials included zinc sulfide-based compounds and perovskite materials. Zinc sulfide exhibits excellent thermal stability, mechanical strength and high carrier mobility, making it a common choice for thin-film transistors and other electronic devices. Doping zinc sulfide with metal elements (such as copper, aluminum or manganese) allows for the creation of different variants, such as zinc sulfide: copper (green) and zinc sulfide: manganese (orange), enabling tunable emission colors by adjusting the frequency of the AC electric field. However, localized electric field breakdown remains a challenge, leading to device damage. Perovskite materials offer adjustable band gaps, narrow half-peak widths, high carrier mobility and efficient fluorescence. When used as the light- emitting layer in perovskite light-emitting diodes, they exhibit high color purity, brightness and a wide color gamut. By modifying the composition of halide ions and adjusting cation proportions, the optical and electrical properties of perovskite can be tailored, showing promise in lighting and display applications. Nevertheless, challenges related to stability, mechanical properties, toxicity, and large-scale manufacturing persist for flexible perovskite electroluminescent materials As demand grows for convenient solutions, electroluminescent devices are expected to serve additional functions, including health monitoring, electronic communication and aerospace applications. Among these, textile displays play a crucial role in transmitting information anytime and anywhere. Wearable electronic products integrated into shoes, clothing and watches enhance human convenience. The acquisition and display of textile electroluminescent devices rely on luminous fabrics and fibers, utilizing printing, coating, lamination and fiber weaving technologies. These methods impose stringent requirements on brightness and device lifespan, necessitating improved device structures and combination modes to achieve stable and durable performance in textile applications. At present, large-scale continuous production of flexible inorganic electroluminescent devices remains a challenge. As new display applications emerge, stricter demands are placed on flexible electroluminescent devices. In flexible inorganic electroluminescent devices, the development and application of electroluminescent devices need to be combined with other disciplines to develop a multifunctional device to meet people's needs.

An efficient inter layer up-sampling filtering algorithm in scalable video coding （SVC） was proposed. Based on different component-sensitive of the human vision system,scheme assigns up-sampling filters depending on the sensi-tivity priority of the image component in order to increase the coding efficiency was proposed. Particularly,a 6-tap filter is assigned for luminance component and a bilinear filter is for chrominance components. The experiment results show that our proposed scheme maintains the performances of coded bit-rate and PSNR value without any noticeable loss,and provides significant reduction in computational complexity. As a result,it can be applied in the inter layer spatial inter-polation of SVC.

An experimental study on low hazard electric plating process is conducted, in view of the disadvantages of the existing system for cyanide plating, which include containing toxic cyanide of the plating solution, the environment pollution, difficulties in disposing and so on. The gold potassium citrate is used as the main salt in the solution for gold electrical plating, to reduce the free-state cyanide ions ionized from the solution in the experimental process. Based on the established solution, experiments are carried out on the copper substrate. Influences of the electric field, flow field, the style of the flush and the distance between anode and cathode on the plating performance are studied experimentally. With the optimized parameters, rather bright surfaces with smaller crystalline grain size and higher bonding strength are obtained. The microstructure of the surface and the substrate are tested by atomic force microscope (AFM), demonstrating that the gold-plated layer is effectively copied and even the roughness of the substrate surface is reduced. Furthermore, the composition of the plating is tested using scanning election mircroscope (SEM) and the plating adhesion is tested by the WS-97 coating adhesion testing instrument, which indicates that the plating performances meet the industry standard.

Epidemiological studies found that the incidence of myopia was increasing year by year and the age of onset of myopia was showing a trend of affecting increasingly younger children. Reducing the occurrence of myopia and controlling the increase of myopia diopter have always been the focus of research on the prevention and control of myopia. Large randomized controlled clinical trials have found that outdoor activities can effectively reduce the incidence of myopia and delay the progression of myopia. Basic experiments also revealed that there were certain connections between light exposure and myopia. We herein review the research progress, limitations and future directions of research on light exposure and myopia. From the perspective of light properties, increasing the intensity of light can slow the progression of myopia and reduce the occurrence of experimentally induced myopia. However, the actual mechanism of action is still unclear. The rhythmic changes of light exposure caused by the light/dark cycle may cause abnormalities in the secretion of melatonin and dopamine, and changes in the circadian rhythm of intraocular pressure and choroidal thickness, thus affecting myopia. The red light, with relatively longer wavelength and forming images behind the retina, tends to induce myopia more easily, while the blue light, with medium and short wavelength and forming images before the retina, tends to delay myopia progression. However, different species respond differently to lights of different wavelengths, and the relationship between light wavelength and myopia needs further investigation. Future research can be done to further explore the mechanism of action of how light exposure changes the progression of myopia, including the following aspects: how light changes dopamine levels, causing changes in downstream signal pathways, and thus controlling the growth of the axial length of the eye; how retinal photoreceptor cells receive light signals of different wavelengths in order to adjust the refractive power of the eyes; and how to design artificial lighting of reasonable intensity, composition and properties, and apply the design in myopia prevention and control., (Copyright© by Editorial Board of Journal of Sichuan University (Medical Sciences).)
