However, the diffraction efficiency of LPIOs is very sensitive to the change of polarization state due to their strong polarization sensitivity, which may result in low diffraction efficiency and poor uniformity of diffraction efficiency over the field of view of an LPIO display system if the change of polarization state is not considered. Here, we developed an approach for polarization efficiency control of freeform LPIOs. The bandwidths of freeform LPIOs were considered, and the change in polarization state was calculated by use of a self-built rigorous coupled-wave analysis (RCWA) module. An optimal balance between aberration correction and efficiency control can be achieved by optimizing the flexible phase profiles of freeform LPIOs. The effectiveness of the proposed method was verified by an example. This work could promote the application of freeform LPIOs in optics and photonics.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 6","pages":"594-600"},"PeriodicalIF":2.2,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148160691","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}

Currently, most 3D display content is limited to virtual scenes, and the production of such content requires a huge amount of time for modeling. In contrast, the capture of real-world scene content relies on camera arrays, which not only involve a complex operation process but also face the problem of high equipment costs. This study proposes a method for generating multiview glasses-free 3D content using Gaussian splatting. The method to achieve a glasses-free 3D display is using lenticular lenses and LCD screens. Then, Gaussian splatting is used to reconstruct the real-world scene. Next, the method to generate off-axis cameras is introduced, and a virtual camera array is added to the reconstructed 3D scene to render multiview disparity images. Finally, multiview 3D images can be synthesized based on these disparity images. This work makes it more convenient and low-cost to obtain disparity images in real-world scenes, which will contribute to enriching the content of glasses-free 3D displays and boost the development of glasses-free 3D technology.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 6","pages":"601-607"},"PeriodicalIF":2.2,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148160743","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}

A temperature compensation mechanism and a dynamic voltage adjustment strategy are jointly integrated to adapt the waveform in real time based on ambient temperature and image content.

Conventional approaches often rely on complex electronic compensation, which offers limited efficacy as they do not address the physical root cause of the interference. This work presents a materials-science-based solution: a novel printhead design incorporating a physically engineered isolation architecture, realized with high-modulus ceramic materials to mechanically decouple adjacent nozzles. Using a validated multi-physics simulation framework that couples structural analysis with computational fluid dynamics (CFD), we systematically engineered the architecture and investigated the performance of various ceramic materials, including alumina and aluminum nitride (ALN). A direct correlation between the material's Young's modulus and crosstalk suppression was established. The optimized design, featuring a 1.0 mm thick isolation wall made of 99.8% alumina (Young's modulus: 370 GPa), achieves an unprecedented droplet volume deviation of less than 0.3%. This study demonstrates a paradigm shift toward passive, materials-based solutions for controlling complex microfluidic systems, offering a direct engineering pathway for the high-yield manufacturing of mura-free displays and other advanced printed electronic devices. A novel inkjet printhead design eliminates mura defects in OLED manufacturing. By incorporating a physical isolation wall made of high-modulus ceramic, mechanical cross-talk between adjacent nozzles is effectively suppressed. This materials-based solution achieves ultra-uniform droplet deposition (&lt;0.3% deviation), enabling the high-yield production of large-area, high-quality OLED displays.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 6","pages":"561-576"},"PeriodicalIF":2.2,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148160668","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}
