Current halo measurement methods mainly focus on the mini-LED partition backlit liquid crystal displays (LCDs) and are nearly all physical-based, limiting their application and generalization ability. In this paper, we propose a simulation-based halo measurement framework, which offers a more flexible evaluation scheme with scene-fused halo generation. Specifically, we first simulate the four existing categories of halo manifestation externally through code, i.e., regular ring-shaped halo, rectangular halo, irregular content-dependent halo, and localized surrounding halo. Then, we build a 3D indoor environment to simulate the laboratory measurement environment, where a micro-LED-based display with variable parameters is taken as the evaluation object. To demonstrate the usefulness of this new and unique halo measurement resource, we conduct both subjective and objective experiments. The high subjective and objective consistency achieved by a simple deep learning-based image quality assessment (IQA) model demonstrates its utility that broadens the scene limits of display design.</div></div>","PeriodicalId":50570,"journal":{"name":"Displays","volume":"88 ","pages":"Article 103006"},"PeriodicalIF":3.7,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous institutions have developed highly-optimized implementations for the mainstream video coding standards, such as x265 for HEVC, VVenC for VVC, and uAVS3e for AVS3. However, these implementations are still not capable of performing real-time encoding of 4K/8K UHD videos without significantly reducing compression complexity. This paper presents a parallel–serial hybrid neural network scheme, specifically tailored to expedite intra-frame block partitioning decisions. The parallel network is designed to extract effective features while minimizing the impact of network inference time. Simultaneously, the lightweight serial network effectively overcomes accuracy issue related to the data dependency introduced by the reconstructed pixels. The proposed enhancement scheme is integrated into the uAVS3 Real-Time encoder. The experimental results for CTC 4K UHD sequences demonstrate a significant increase in encoding speed (+30.2%) and an improvement in encoding quality, as evidenced by a 0.24% reduction in BD-BR. Compared to the previous work, we achieve the optimal trade-off in these two critical metrics.

All proposed circuits are fabricated with low-temperature polysilicon technology, which is compatible with mainstream display backplane manufacturing processes. The characteristics and positive bias stability of the implemented thin-film transistors have been validated. Additionally, a comparative analysis is conducted against existing pixel designs. The circuits’ performance was evaluated under varying Gate pulse widths and driving voltages to determine the optimal driving strategy. With the appropriate driving voltage, the SRAM structure is capable of achieving an output exceeding 20 V. Moreover, the holding time, long-term operational stability, and illumination stability of the circuits were evaluated and compared. Experimental results demonstrate that the SRAM structure outperforms in both output performance and stability. An active-matrix digital microfluidic chip with a 640 × 280 array was fabricated using the SRAM pixel structure, which highlights its scalability. The simplified circuit structure, coupled with an output voltage exceeding 20 V, addresses the limitations of conventional pixel circuits for digital microfluidic applications.
