However, traditional multilayer thin-film simulations—based on the assumption of dipole emitters embedded in infinite planar layers—fail to capture the three-dimensional optical effects of microOLEDs. This is primarily due to their micrometer-scale pixel size, which becomes comparable to the vertical dimensions of the device, and the presence of a pixel define layer (PDL). To address these limitations, finite element methods (FEM) and finite-difference time-domain (FDTD) methods are commonly employed. However, these methods typically demand substantial computational resources, limiting their uses to the illustration of specific optical characteristics and trends rather than enabling a full quantitative analysis. This study introduces an optimized FEM-based simulation method for micro-scale OLEDs embedded with multiple dipole sources. By incorporating randomly distributed dipole sources with varied positions, orientations, and relative phases, the proposed approach enables accurate far-field radiation pattern calculations while significantly reducing computational burden and simulation time, offering a promising pathway toward comprehensive optical analysis of microOLEDs and thus improving the understanding of light extraction and propagation at the micro-pixel level.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 1","pages":"3-11"},"PeriodicalIF":2.2,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145993922","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 effectiveness of EPD technology relies on optimized driving waveform design to ensure display clarity and minimize response time. However, despite advancements, existing EPD techniques continue to face critical challenges such as ghost images, flicker, and long response times, all of which can detract from user experience. To address these issues, this paper proposes a novel EPD driving waveform design algorithm that integrates physical simulation and a dynamic programming approach. This algorithm is designed to identify the optimal driving path, thereby significantly reducing response time while effectively minimizing ghost images and flicker. Experimental results demonstrate that the proposed algorithm effectively mitigates ghost images and flicker, achieving shorter response time and higher display quality in 16-level grayscale print-style color EPD.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 12","pages":"1114-1122"},"PeriodicalIF":2.2,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145699028","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}

We developed a measurement setup to analyze far-field EL emission across various wavelengths and compared the results with 1D optical simulations. This approach allowed us to observe the well-known dependence of emission directivity and light extraction efficiency (LEE) on the structural parameters of flip-chip LEDs, particularly the thicknesses of p-GaN and n-GaN layers, and to quantify the impact of total thickness variation resulting from wafer thinning processes. Using larger LEDs, the test vehicle offers a valuable tool for designing micro-LEDs with the desired directivity and for process monitoring. We also observed that the angular dependence of far-field emission varies with the applied bias and demonstrated how this could affect wafer-level micro-LED characterizations. Finally, we showed that the far-field EL emission of micro-LEDs progressively deviates from the description by a 1D optical cavity alone, suggesting an increasing influence of the limited size and necessitating 3D-FDTD simulations to accurately model both vertical cavity and sidewall effects. However, for sizes down to 5 μm, the directivity predicted by a 1D model seems roughly preserved.</p>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 12","pages":"1123-1134"},"PeriodicalIF":2.2,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sid.onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.2114","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145698982","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}
