To address chromatic wavefront noise issues commonly found in conventional half-waveplate-based SIDH systems, we explore a SIDH system incorporating a quarter-waveplate-based GPL (QW-GPL). In particular, we resolve angular polarization-dependent noise in QW-GPL wavefront modulation by utilizing circularly polarized Bragg reflection of CLC as a circular polarization filter. This approach ensures an ideal circularly polarized beam state across a wide range of incident angles and wavelengths. By effectively mitigating circular polarization distortion in QW-GPL, our method significantly improves the quality of reconstructed holographic images in full-color SIDH with a compact form factor, as demonstrated by reduced entropy values.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 5","pages":"553-565"},"PeriodicalIF":2.2,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.2078","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598496","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}

Here, we developed advanced inkjet printing processes for fabricating high-resolution 264-ppi QD-LED displays. The analysis and optimization of rheological properties of inks for printing charge transporting layers and QD emissive layers have been studied using a piezo axial vibrator (PAV) which provides useful rheological information for inkjet printing. In addition, post-inkjet processes, such as drying and thermal baking, are optimized to produce high-performance devices. This work demonstrates that the IJP is a promising technology for cost-effective large-scale production of high-quality QD-LED displays suitable for high-quality TVs, monitors, and IT products including tablets and laptops.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 5","pages":"566-575"},"PeriodicalIF":2.2,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598497","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}

During the MISF fabrication process, we could obtain conventional oxide TFTs (SW-TFTs) by etching out the bottom ferroelectric (FE) layer. This leads to the advantage of fabricating both FE-TFT and conventional oxide TFT simultaneously. The fabricated FE-TFTs exhibited a memory window of 9.1 V and showed stable operation under bending on a cylinder of 1 mm radius. The FE-TFTs were first fabricated on the PI substrate and cut and transferred onto a PDMS substrate to achieve a stretchable device. The devices maintained stable operation under biaxial stretching up to 30% and demonstrated reliable performance for 100 hrs. For display application, we proposed a 3T0C circuit with FE-TFTs without a capacitor for pulse-width modulation (PWM) mode in micro-LED displays.

The fundamental transformation is based on flexible display technology, and to achieve higher form factor innovation and variations, the development of stretchable displays is currently necessary. In this paper, we have demonstrated the first result of 200PPI stretchable display by applying serpentine-shaped bridge design with a micro-light emitting diode (micro-LED) based on the conventional display process, overcoming fundamental limitations of two existing development directions, pixel density and the stretchability. Methods like Kirigami remove portions of the substrate to implement structural stretchability, offering a high pixel resolution and maintaining image quality by using existing processes. Our new structure, which demonstrates high pixel resolution without any degradation of stretchability, is expected to play a key role in the realization of stretchable displays for the television, IT, and automotive markets, and to accelerate the innovation of display form factors in the near future.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 5","pages":"524-532"},"PeriodicalIF":2.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598207","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 display forms a high-resolution 3D image that is floating in mid-air. LeAIRR reduces image degradation caused by the micro-corner-cube prisms in the retro-reflector. The prisms cause ray shift and diffraction, which decrease the resolution. The edges of prisms also cause scattering, which decreases the contrast. LeAIRR reduces diffraction and scattering effects by employing a lens to make the aerial image and the retro-reflector optically conjugate, after which the retro-reflected light is focused by a convex lens. Furthermore, the convex lens performs optically reduced imaging of the corner-cube prisms on the aerial image position. Thus, the ray shifts caused by the prisms are reduced. Our prototype of the aerial 3D display provides the contrast transfer function (CTF) to be 2.5 times better than the conventional aerial 3D display based on the AIRR optical system.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 5","pages":"472-481"},"PeriodicalIF":2.2,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.2056","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598197","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}

However, it has been suffering from significant stability issues, particularly under photoirradiation. Previous studies have reported that zwitterionic ligands can enhance photostability via a chelate effect derived from specific substituents. However, the mechanism by which zwitterionic ligands improve photostability remains unclear.Therefore, we investigated the substituent spacing in zwitterionic ligands to elucidate how they improve the photostability of PeNCs. We found that the key factor is the proportion of zwitterionic ligands on the PeNC surface, acted by the chelate effect. SB3, the ligand bearing three carbon atoms between its substituents, achieved 87.4% surface coverage- significantly higher than that of ligands with other substituent spacings. Consequently, this high coverage critically enhanced the photostability, enabling PeNCs@SB3 to maintain their photoluminescence quantum yield (PLQY) for 30 hours under photoirradiation. We propose a novel perspective on ligand engineering strategies that focuses on the ligand proportions on the surface of PeNCs to improve their photostability.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 5","pages":"464-471"},"PeriodicalIF":2.2,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.2055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598196","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}
