The current detection circuitry and the holding elements consist of thin-film devices using the metal-oxide semiconductor amorphous indium gallium zinc oxide (a-IGZO). Moreover, the array control and readout circuitry is also realized by a-IGZO thin-film transistors (TFTs), creating decoders and multiplexers. This makes the sensor arrays easy to combine with display backplanes using a-IGZO TFTs. An example is the low-temperature polycrystalline oxid (LTPO) backplane used in OLED displays.

However, instabilities in the manufacturing process often result in luminance nonuniformities, commonly known as Mura. As an effective approach to enhancing display performance, Demura compensation algorithms are typically integrated into the driver IC to eliminate such defects. In this work, a boundary-aware strong/weak filtering framework operating in the luminance error domain is proposed for Demura compensation. The proposed method performs multistep processing on the acquired luminance error data, evaluates local luminance discontinuities according to Mura characteristics and the target correction luminance, and selectively applies strong or weak filtering to optimize the spatial distribution of luminance errors while preserving intrinsic luminance structures. Experimental results demonstrate that the proposed method significantly improves luminance uniformity: For the green channel at a gray level of 32, the uniformity of brightness (UOB) reduces from 0.0818 to 0.0516, corresponding to a 37% improvement; at gray levels of 64 and 192, the UOB decreases by 35% (from 0.0556 to 0.0359) and 24% (from 0.0275 to 0.0210), respectively. Visual comparisons before and after Demura compensation further confirm that the proposed strong/weak filtering–based Demura algorithm effectively suppresses luminance nonuniformity.\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 10","pages":"814-825"},"PeriodicalIF":2.0,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149125930","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}

This study explores the color range of real-world scenes and examines the extent to which real-world colors fall outside the sRGB and even the more modern DCI-P3 color gamut. It further evaluates the capability of OLED displays with ultra-Wide Color Gamut (ultra-WCG—referring to a gamut larger than DCI-P3) to accurately reproduce these colors and identifies which color areas remain unproducible on such displays. The results show that a significant number of real-world images fall within the boundaries of the sRGB and mostly DCI-P3 color spaces. However, certain colors, such as cyan, pure green, or highly saturated reds and yellows, fall outside these gamuts, which suggests that some ultra-WCG displays, such as our test vehicle (a QD-OLED television) enable more accurate reproduction of a larger, more impactful portion of the colors we encounter in real life, without needing the full gamut of BT.2020.\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 9","pages":"735-745"},"PeriodicalIF":2.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148903973","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 μFE is the highest among metal–oxide semiconductor (OS) TFTs using common semiconductor materials and mature production processes. Moreover, the subthreshold swing (S) is 0.13 V/dec, and the threshold voltage (Vth) is 0.0 V, which are also superior. These excellent characteristics are accomplished by inherent features of the polycrystalline phase and IGO material. The mobility modeling is executed by the modeling procedure once we developed and clarifies that due to a behavior of potential barriers at grain boundaries, the intrinsic mobility (μ) positively depends on the carrier density (n), which enhances the μFE. The μ-n dependence can be a universal curve and is indispensable to design devices and circuits in the future. Moreover, the self-heating simulation is executed by implementing the T-dependent μ-n dependence and clarifies that the μ slightly but also positively depends on the temperature (T), which also enhances μFE.

This study investigates how cognitive load modulates color saliency in guiding children's visual search. Using a visual search paradigm, color saliency was manipulated through color difference (ΔE*₀₀) between targets and distractors, and cognitive load was manipulated through task difficulty (simple detection vs. localization) and amount of information (set sizes: 6–21). Results showed cognitive load moderated color saliency: large color differences (ΔE*₀₀ ≥ 72.69) became more beneficial under high task difficulty. Target hue further modulated saliency under high load: Red and green targets facilitated the fastest searches, whereas blue and purple incurred a 50- to 60-ms cost. Notably, task difficulty reversed the effect of information load: Increasing set size prolonged reaction times under low difficulty but shortened them under high difficulty by 35 ms, suggesting context-dependent strategy switching. These findings suggest that color saliency dynamically interacts with cognitive load, offering three preliminary design implications. First, high-load tasks may benefit from high-contrast color combinations (e.g., red-green, ΔE*₀₀ > 70). Second, critical information may favor red or green hues over blue or purple. Third, information density should be calibrated to task demands rather than minimized indiscriminately.\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 9","pages":"754-768"},"PeriodicalIF":2.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904097","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}

Switchable privacy displays (SPDs) can electronically change between multiple viewers (public) and a single on-axis (private) user. This technology gained worldwide attention by the introduction of the first smartphone equipped with an SPD in March 2026. Applications of SPDs are introduced with a focus on automotive codriver displays, as these are the most demanding use case in terms of driver distraction (safety) and high image quality for the codriver. The associated optical measurements to judge on the performance of SPDs (most important are the horizontal viewing angle characteristics) can easily be transferred to other applications with respect to their geometric and ambient light conditions. The evaluation of switchable privacy for codriver displays was performed with 20 participants. Additionally, an efficient proposal for standardization of switchable privacy mode displays is presented on the basis of easy-to-measure luminance values.","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"34 9","pages":"769-785"},"PeriodicalIF":2.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.70091","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148903791","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}
