In these cases, remote skilled workers have to provide a step-by-step guide by observing the onsite situation around the large task spaces in three dimensions, instructing onsite unskilled workers on how to perform the tasks with the correct hand gestures at the right position, and switching between observation and instruction frequently during the remote support. In this study, we developed a Metaverse-based remote support system with a seamless user interface for switching between free viewpoint observation and hand gesture instruction. The proposed system enables remote skilled workers to observe the onsite field from any viewpoint, transfer hand gesture instruction to onsite workers, and seamlessly switch between free viewpoint observation and free hand gesture instruction without having to change devices. We compared the time efficiency of the proposed system and a conventional system through experiments with 28 users and found that our system improved the observation time efficiency by 65.7%, the instruction time efficiency by 27.9%, and the switching time efficiency between observation and instruction by 14.6%. These results indicate that the proposed system enables remote skilled workers to support onsite workers quickly and efficiently.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.1339","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141650665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The foveated rendering method significantly reduces the computational requirements during rendering by reducing image quality in peripheral regions. In this paper, we propose a scene-content-sensitive real-time adaptive foveated rendering method. First, we pre-render the three-dimensional (3D) scene at a low resolution. Then, we utilize the low-resolution pre-rendered image as input to extract edge, local contrast, and color features. Subsequently, we generate a screen-space region division map based on the gaze point position. Next, we calculate the visual importance of each 16 × 16 pixel tile based on edge, local contrast, color, and screen-space region. We then map the visual importance to the shading rate to generate a shading rate control map for the current frame. Finally, we complete the rendering of the current frame based on variable rate shading technology. Experimental results demonstrate that our method effectively enhances the visual quality of images near the foveal region while generating high quality foveal region images. Furthermore, our method can significantly improve performance compared to per-pixel shading method and existing scene-content-based foveated rendering methods.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141649817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High display resolution requires narrower signal line integration, intensifying the coupling effect. Traditional methods like Vcom feedback and increasing analog voltage drain-drain (AVDD) load are slower and less accurate, leading to increased power consumption. In response, we propose an advanced digital signal compensation method. In this study, we developed a predictive model and investigated the intricate relationships among AVDD, Vcom, and storage capacity (Cst) ripples on horizontal crosstalk. Optimizing the ripple change (∆G) by varying the compensation coefficient (a) and decay ratio (τ) significantly reduces crosstalk effects. The digital compensation method allows rapid and precise compensation without delays, reducing horizontal crosstalk in 8K LCD panels from 4% to below 0.9%. This surpasses the requirement of minimizing crosstalk to less than 2%, substantially enhancing the image quality of high-resolution displays.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141670497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasma etching shows great potential in making subwavelength antireflection structures for its advantage of scalable, low-cost, and applicable in flexible substrates. Here, we demonstrate an antireflection nanostructure by O2 plasma etching on poly (ethylene terephthalate) (PET) substrate without additional corrosive gas species or antireflective coatings. Nanopores on the surface were formed due to the different etching rates of the organic region and silica region of the surface. The solar weighted average transmittance was improved from 91.6% to 94.8% for single-side treated PET with silica antiblocking layer. The transmission increment was attributed to the gradient refractive index of the nanostructured surface due to the elimination of step discontinuity in refractive index. The result shows a highly efficient, eco-friendly, solvent-free, economical, and sputtering target-free method for reducing the reflection and increasing the transmittance of the substrates.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141584120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The OLED emitting is successfully survived. Deuterium atoms (isotopes of hydrogen) with heavier atomic weights can strengthen C-D bonds, slow down the kinetic rate for unwarranted chemical reactions, and improve the performance and stability of OLEDs. In this study, deuterated D-Ir (mppy)3 was employed as the dopant in the emitting layer of green OLED to replace the general Ir (mppy)3 to improve the optoelectronic properties and extend the lifetime of green OLED. At a constant voltage of 4 V, the initial luminance and half lifetime of general Ir (mppy)3 doped and deuterated D-Ir (mppy)3 doped OLEDs are 188.1 cd/m2, 7.2 h and 438.3 cd/m2, 42.8 h, respectively. It is shown that doping the deuterated D-Ir (mppy)3 material in the emitting layer has the effect of prolonging the lifetime of OLED.
