Summary: Wide color gamut white light-emitting diodes (WLEDs) based on high-performance CdSe-based heterostructured nanoplatelets (NPLs) are reported. The NPLs, including CdSe/CdS and CdSe/ZnCdS, exhibit excellent photoluminescent properties and achieve an ultrawide color gamut covering 141.7% of the NTSC standard. This research demonstrates the huge potential of colloidal semiconductor NPLs for applications in new-generation lightings and displays.

Summary: A new process of crystallizing amorphous silicon without melting is proposed, which includes adding a molybdenum layer to control crystallite size and achieve high-quality crystallization at low temperature. Simulations show that the transfer of energy from the molybdenum layer to the silicon film can lead to crystallization of amorphous silicon at temperatures lower than its melting point.

Summary: This paper proposes a lightweight YOLO-ADPAM detection method based on an attention mechanism to solve the problem of unable to correctly evaluate the number and type of mura defects on the image in the field inspection of TFT-LCD panels. The proposed method utilizes a clustering algorithm and a parallel attention module to improve the accuracy and stability of bounding box regression and enhance the detection accuracy of the algorithm. Experimental results show that the proposed YOLO-ADPAM algorithm achieves a mAP of 98.20% and a detection speed of 83.23 FPS, meeting the accuracy and real-time requirements of TFT-LCD defect detection tasks.

Summary: This study examines the topological structure and COVID-19 related risk propagation in TFT-LCD supply networks. The results show that TFT-LCD supply networks have a 'hub and spoke' feature and a 'robust-yet-fragile' configuration. Additionally, hidden risky sources in the main TFT-LCD manufacturers and suppliers and in interfirm cooperations are revealed. These findings will help managers reduce vulnerability and create more robust and resilient networks.

Summary: Tetramethylammonium Hydroxide (TMAH) is widely used in the TFT-LCD industry, and this study evaluated the treatment of synthetic and real TMAH wastewater using combined hydrolysis acidification-aerobic and anaerobic batch reactors. The results showed stable TMAH degradation with high organic carbon removal efficiencies. Microbial community analysis indicated mixed microbes played a role in TMAH degradation, with anaerobic treatment being favored.

Summary: This study aimed to compare the amount of heavy metals deposited on CRTs and LCDs and their risk assessment. The average concentrations of heavy metals in the dust on CRTs were higher than LCD screens, and ingestion was found to be the main route of exposure in both types of monitors. Cancer risk of studied elements in dust can be ignored as the Risk Index was less than 10(-4).

Summary: A novel autostereoscopic display using inclined interleaved linear Fresnel lens arrays is designed and evaluated, providing different high-resolution stereoscopic image pairs to two viewers simultaneously through time-division quadruplexing. The lens array's inclination enlarges the viewing zone horizontally, enabling two viewers to have specific views without interference. This allows for direct manipulation style interaction and collaboration while maintaining eye contact, without the need for special goggles.

Summary: This study proposes two polarization interference filters (PIF1 and PIF2) for achieving a wide color gamut in liquid crystal displays (LCDs). The PIFs effectively eliminate unwanted parts of the output spectrum, improving the color gamut of LCDs. The PIFs have a higher color gamut enhancement ratio (CGER) compared to high-performance color filters.
