While VRR can reduce power consumption, it can cause flicker issues for users when the refresh rate is lowered below 60 Hz or when the refresh rate is changed even above 60 Hz. Since users can perceive both types of flicker as similar image artifacts, we developed the integrated flicker index to predict them. We introduced time-domain analysis using impulse response functions (IRFs) to capture the onset of aperiodic luminance fluctuations in the VRR waveform and interpret human response to these fluctuations. In addition, based on the previous studies that display characteristics (e.g., luminance and size) affect flicker experience, we need to incorporate both effects of brightness and size into IRF. For this purpose, we utilized the converted IRFs from the TCSF model, which can explain these two effects. To validate the integrated flicker index, we conducted three experiments: flicker when the refresh rate is reduced below 60 Hz flicker (Exp1 and 2) and VRR flicker when the refresh rate is changed (Exp3). The results demonstrate that IRF converted from the appropriate TCSF could offer a more accurate prediction of flicker experience of VRR displays.</p>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 11","pages":"1076-1091"},"PeriodicalIF":2.2,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sid.onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.2107","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145443087","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}

Although recent studies have primarily focused on image-level anomaly detection, pixel-level anomaly segmentation remains underexplored due to the lack of annotated defect data. In this paper, we propose <i>AnoSeg</i>, a novel anomaly segmentation framework designed to directly generate accurate anomaly maps without requiring real defective samples. AnoSeg integrates three key techniques: (1) a hard augmentation strategy for synthesizing defect-like anomalies from normal images, (2) self-supervised learning with combined pixel-wise and adversarial losses to enhance segmentation quality, and (3) coordinate channel concatenation to incorporate spatial priors relevant to defect localization in structured panel layouts. By training on only normal and synthetically augmented data, AnoSeg learns to segment anomalous regions robustly and generalizes well to unseen defects. Additionally, the resulting anomaly maps can be leveraged to improve conventional anomaly detection performance. Experimental results on the MVTec Anomaly Detection (MVTec-AD) benchmark demonstrate that AnoSeg outperforms existing state-of-the-art methods in both segmentation accuracy and detection performance, as measured by intersection over union (IoU) and AUROC metrics. These results suggest the practical applicability of AnoSeg for high-precision surface inspection in intelligent display manufacturing systems.</p>\u0000 </div>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 11","pages":"1059-1067"},"PeriodicalIF":2.2,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145442936","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}

Our previous work demonstrated rare-earth doped oxides are ideal channel layer materials for TFTs due to their superior mobility and stability. However, scaling up TFT production from pilot lines to mass manufacturing poses significant challenges, largely because of the complexity of multi-element composite materials and intricate processes. In this study, an end-to-end graph convolutional network (GCN) model is employed to optimize TFT production processes. By encoding process parameters as graph nodes and features, the GCN effectively predicts critical drain current–gate voltage (I–V) characteristics, enabling precise calculation of electron mobility, subthreshold slope, and threshold voltage. The model achieves a mean absolute percentage error of 19.9% on validation data. Based on the optimized parameters, a TFT device with properties including a mobility of 37.8 cm<sup>2</sup>/Vs, a threshold voltage of 0.9 V, and a subthreshold slope of 0.62 V/dec was successfully produced.

Therefore, a new multi-stage reset driving scheme based on a sawtooth function was proposed, which could effectively solve these defects. It consisted of a shrinking stage and a stabilizing stage. First, the proposed driving scheme was driven by a negative voltage by analyzing the voltage characteristic curve. Second, based on the splitting theory, an exponential function was applied to make the pixel's oil rupture quickly. Then, a sawtooth function was applied to enable oil to achieve secondary fusion during the cyclic driving process, effectively reducing the dispersed residual oil in pixels. Finally, a reset signal was introduced to release captured charges and suppress oil backflow.
