Building on our previous work, we conducted a color-matching experiment using a simulation setup that optically merges a display and printed background via a half mirror. Fifteen observers matched the test colors to either printed targets or printed targets with AR overlays across four lightness levels and six hues, with precise geometric registration maintained throughout the experiment. We analyzed the results using perceptual weighting functions and distance-based metrics. The perceptual weighting coefficients were consistently close to unity, indicating minimal discounting between the virtual and physical components. The color differences between targets and the mean of the matched colors were generally small, and the matched colors clustered closely around their respective targets. The observed mean color difference from the mean (MCDM) was comparable to the previously reported observer variability, while the mean color difference from the target (MCDT) was approximately 1.2 times the MCDM. Although lightness and hue had statistically significant effects on matches, their absolute impacts remained minor. These findings demonstrate that accurate geometric alignment substantially mitigates color appearance shifts in OST AR, even under varying stimulus conditions.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 4","pages":"126-134"},"PeriodicalIF":2.2,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686923","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}

To achieve this goal, we replace the residual-in-residual dense block (RRDB) used in Real-ESRGAN with a novel residual-in-residual sparse block (RRSB) and further apply similarity-based pruning techniques to RRSB for lightweight optimization. Additionally, we introduce the Improved residual-in-residual sparse block (IRRSB), which reduces both the number of input variables and the number of modules within each block. Our approach achieves an 85% reduction in parameters and a 79% decrease in computational workload compared to the original architecture. The framework is specifically designed to upscale old film images, such as those from VCD sources, to HDTV resolution by processing low-resolution inputs and generating outputs with up to 9–16× pixel magnification while effectively minimizing artifacts and blurring. Objective evaluations utilize standard metrics including peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), and natural image quality evaluator (NIQE). Despite the significant reduction in computation, PSNR decreased by only 0.7% dB and SSIM by 3%, while NIQE improved by 13%, indicating an overall enhancement in natural image quality. These results demonstrate that the proposed IRRSB framework maintains strong performance while significantly reducing model size and computational complexity.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 4","pages":"164-179"},"PeriodicalIF":2.2,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686767","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}

Herein, we demonstrate air-cavity optics for the efficiently light-emissive light guide plate (LGP), giving the largest size for the FLU reported so far. Our LGP was composed of a transparent plate integrated with the functional film with internal air-cavities. A large difference in refractive index at the air-cavity interface lowers the critical angle, making it more efficient for light to be redirected to the reflective display by total internal reflection (TIR), leading to high efficiency of light extraction. Simulation suggests that light extraction efficiency of embedded air-cavity optics is much higher than that of conventional collimation optics, such as the LGPs reported so far. The effective extraction could also be attributed to a decrease in the size and/or distribution density of cavities, leading to high transparency. The optical design of the cavity shape could give a high contrast ratio in the field of view. A preliminary prototype of the LGP with an E-paper display showed excellent readability in both environments with and without ambient light. A high uniformity of brightness of the large-sized LGP was found.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 4","pages":"180-187"},"PeriodicalIF":2.2,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147687001","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}

However, when drivers turn their heads to observe road conditions, the brightness of existing HUD may reduce sharply. What is more, for a driver, the head movements in horizontal direction are usually much larger than movements in vertical direction. Therefore, the viewing angle of a HUD should be regulated to have larger horizontal angle. This paper designs an optical film with microstructures to regulate viewing angle of HUD based on digital light processing (DLP) projection. A simulation model is established in the optical design software LightTools. The simulation results show that the horizontal viewing angle of 50% maximum luminance increases from 14° without the optical film to 40° with the optical film. The optical film with the designed microstructures is prepared and measured. The practical measurement results indicate that the horizontal viewing angle of 50% maximum luminance increases from 14° without the optical film to 36° with the optical film, which proves the optical film can significantly expand the horizontal viewing angle. The proposed microstructure design method enables independent control of horizontal and vertical viewing angles, thereby accommodating a variety of application scenarios.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 4","pages":"135-144"},"PeriodicalIF":2.2,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686186","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}
