Abstract ：
光刻法是一种制备微型发光二极管(Micro-LED)像素化色转换薄膜的可靠方案,但存在量子点与光刻胶兼容性的难题.本文开发了一种通过N-苯基马来酰亚胺(NPMI)侧链改性的丙烯酸树脂制备兼容量子点的光刻胶,侧链基团上C==O键能与量子点形成配位键从而钝化表面缺陷,并提高量子点分散性,使光刻胶溶液的量子产率(PLQY)达到76.1%(红色)和43.4%(绿色).最终制备色转换薄膜时钝化效果仍然存在,绿色和红色的PLQY分别达到了66.4%和36.4%,像素化图形最小尺寸可实现10 μm×10 μm的矩形阵列.本研究中的树脂侧链改性方法为开发兼容量子点的光刻胶提供了指导,为Micro-LED全彩化的商业化应用提供了一种简便且可行的解决方案.

Abstract ：
量子点(Quantum dots)凭借其尺寸可调控、卓越的光致发光量子产率(PLQY)以及宽光谱吸收等特性,展现出了卓越的光学性能,使其成为全彩广色域显示中LED色转换层的理想材料选择.特别是MAPbBr3钙钛矿量子点(PQDs),不仅制备工艺简单,并且还拥有优异的光电性能,因而被视为极具商业化潜力的材料.然而,MAPbBr3 PQDs在合成后其表面的配体极易脱落,导致表面缺陷态密度增加,这使得它们在水氧等环境因素下稳定性较差,最终导致其PLQY进一步降低.本研究提出了一种高效的一步合成MAPbBr3 PQDs策略:通过配体辅助再沉积技术(LARP),并创新性地使用2-己基癸酸(DA)配体替换传统的油酸(OA)配体,在室温条件下成功地合成了具有出色稳定性和高PLQY的MAPbBr3 PQDs.与单长碳链的OA配体相比,双短链的DA配体能与MAPbBr3 PQDs建立起更强的配位键.配体与PQDs之间的强相互作用有助于全面钝化晶格缺陷,从而减弱非辐射过程并提高材料的环境稳定性.因此,DA修饰后的MAPbBr3 PQDs不仅展现出高达 87.8%的PLQY,而且在水氧环境中也表现出更高的稳定性.室温环境下,使用DA配体修饰后的MAPbBr3 PQDs的PL峰值在放置半个月后仍保持在原来的68.3%,而OA配体修饰的PQDs表现出几乎完全的荧光猝灭.随后,将DA配体修饰后的绿色发射MAPbBr3 PQDs、红色发射CsPbBrI2 PQDs以及蓝色发射CsPbCl1.5Br1.5 PQDs置于聚苯乙烯(PS)环境中包覆固化成膜,替代传统荧光粉应用于显示器件发光二极管(LED)的色转换层,测试其色域范围达到了NTSC标准的137.09%.

Abstract ：
全无机钙钛矿量子点因其高光致发光量子产率(Photoluminescence Quantum Yield,PLQY)、带隙可调、高色纯度等特性,在宽色域显示上的应用十分广泛,但其表面缺陷与晶格不稳定限制了其进一步应用.通过热注入法将ZnI2作为掺杂剂成功合成了 Zn2+掺杂的CsPbI3量子点(Zn:CsPbI3量子点).试验表明,Zn部分取代了 Pb,钙钛矿晶格逐渐收缩但晶型保持不变,提高了辐射衰减率,有效消除量子点缺陷态.Zn:CsPbI3量子点相较于原始CsPbI3量子点具有更好的相稳定性,PLQY也从56％提升至98％,同时PLQY在10天后仍可保持在80％以上.选用窄发射的Zn:CsPbI3,CsPbBr3与CsPbCl3量子点作为LED颜色转换材料,在国家电视标准委员会(National Television Standards Committee,NTSC)标准下,其色域达到了135.22％,证明了其在直视型LED显示屏或者液晶显示器(Liquid Crystal Display,LCD)背光领域具有潜在应用前景.

文本到图像生成是一项极具挑战性的跨模态任务,目标是根据给定文本描述生成对应的图像.尽管现阶段相关研究在视觉呈现方面效果优异,但仍存在细节表达不够精细、语义一致性欠佳等问题.基于此,文章提出了一种基于语义增强的生成对抗模型,将文本进行编码后送入条件增强模块进行处理,丰富文本语义特征.在生成网络中,添加一个自适应块,在仿射变换前将上一层的输出和文本语义信息输入自适应块进行进一步的信息增强.并通过引入对比损失,提高文本与生成图像之间的语义一致性.将这一方法在MSCOCO和CUB birds 200 两个数据集上进行训练测试,实验结果表明,与其他模型相比,性能得到了较高提升.

Abstract ：
手物体交互图像的生成是计算机视觉和人机交互领域的一个重要挑战.准确生成这类图像对于理解物体可供性、改进人机交互系统以及增强虚拟现实体验至关重要.然而,现有方法在处理复杂物体、罕见姿势和遮挡关系时仍面临诸多困难,常常导致生成的手部形状、位置和姿态存在不自然或失真的情况.鉴于此,文章提出了一种基于扩散模型的两阶段方法,用于从单一RGB物体图像生成手物体交互图像.该方法包括两个关键组件:MaskNet和FusionNet.其中,MaskNet负责预测手物体交互的空间布局;FusionNet则基于预测的布局生成详细的交互图像.文章利用扩散模型的强大生成能力,在潜在空间中进行高效的图像生成.实验结果表明,该方法在生成真实、多样化的手物交互图像方面表现出色,在FID、LPIPS和UPR等指标上均表现良好.此外,该方法还展现出良好的泛化能力,能够处理未见过的物体类别和复杂场景.

Abstract ：
The pancake structure is the mainstream optical solution for virtual reality (VR) displays due to its compact, folded optical path. However, only a small portion of the light can pass through the pancake optical engine because the incident light has to be polarized and directed to the half mirror (HM) twice. In order to improve the optical efficiency, a new pancake optical engine is proposed for VR display, which employs a diffractive deflection film (DDF) with different focal lengths in three regions and two cholesteric liquid crystal (CLC) lenses that respond to circularly polarized light. The CLC lenses are modeled, and their polarization response characteristics are verified. The pancake system is simulated and optimized in terms of image quality and evaluated for optical efficiency, achieving 2.86 times the optical efficiency of the conventional pancake system, and the root mean square (RMS) radius of the system is controlled within 19 mu m, and the modulation transfer function (MTF) at the cut-off frequency is greater than 0.2. The results indicate that this structure has great potential in the VR display field.

Abstract ：
This study introduces a multi-layer grating device aimed at enhancing color stability in tunable structural color and optical encryption. The device ensures both transmission efficiency and stability within the microfluidic tuning system by incorporating transition and protective layers, along with an amplified grating period. Analytical results demonstrate that the combined effect of surface plasmon waves (SPW) between the multi-layer films generates the full color spectrum solely by altering the grating period. This grating period has been effectively expanded to approximate the intended color band. Compared to single-layer gratings, the period has increased by 238%, and for multi-layer gratings, it has increased by 147%. Nanometal gratings with periods of 400, 500, and 600 nm successfully produce primary colors, with respective transmittance rates of 75.8%, 75.9%, and 71.8%. Additionally, we propose an FDTD simulation method using two orthogonally polarized Gaussian light sources to model more scenarios. The dynamic structural color capabilities of these devices in the context of microfluidics hold promising potential for applications in optical encryption and could be easier to manufacture due to the larger grating period, making the process more cost-effective compared to existing devices.

Abstract ：
Electrophoretic display technology is a reflective display technology characterized by low energy consumption, eye protection, and good visibility, making it one of the most promising new display technologies. Due to their extremely small size, cadmium selenide quantum dots(CdSe QDs) exhibit poor electrophoretic stability when used as electrophoretic particles. To address this issue, this study employs grafting polymerization to load CdSe QDs onto TiO2 particles, resulting in white fluorescence electrophoretic particles with excellent electrophoretic performance. Additionally, the pigment green 7 particles were modified using surface modification techniques with octadecylamine (ODA), producing green electrophoretic particles with good dispersibility and fast electrophoretic speed. Under dual-mode (electric field drive and UV light photoluminescence), the technology achieves multi-modal electrophoretic displays of white, green, and fluorescent colors. © 2025, John Wiley and Sons Inc.

Abstract ：
The technology of combining waveguides and collimation provides more optimization space for near-eye display systems. It not only enhances display performance (such as brightness, clarity, eye box range, etc.), but also enables a more compact and efficient design. This combination has become one of the most important technologies in VR and AR devices, continuously driving innovation in display technology. Experimental results show that 80% of the collimated light is concentrated within a±10° range, and the waveguide greatly increases the eyebox range while maintaining over 75% global uniformity. © 2025, John Wiley and Sons Inc.
