However, the display quality of degraded document images on E-paper often suffers from a lack of detail. To address this challenge, we introduce a mapping model that converts color images into E-paper display images. This model leverages U-Net++ as its backbone, integrating residual connectivity and dual attention modules. Given the presence of varying stroke thicknesses in document images, a fixed-size convolutional kernel is insufficient. Therefore, we propose multi-branch channels and spatial attention modules (MCSAM), which combines the selective kernel network (SKNet) with a spatial attention mechanism to adaptively select the appropriate convolutional kernel size based on font size. To demonstrate its effectiveness, we tested the mapped images on a custom E-paper display platform.

The perceived quality of images seen on displays can be affected by lighting, contrast, and spatial characteristics of the content. While past studies investigated the impact of display luminance and ambient illuminance on preference and discomfort, granular perceptual qualities, such as visual clarity, interest, and complexity, have been rarely investigated. This study investigates the potential use of lighting and image quality metrics to develop a computational model of viewers' response to images of indoor environments shown on a display. In a psychophysical experiment, 42 participants evaluated images of indoor environments under different display luminance (50 cd/m<sup>2</sup> and 250 cd/m<sup>2</sup>) and ambient illuminance (50 lx, 150 lx, 450 lx, and 900 lx) conditions. Ambient illuminance and display luminance had minimal impact on perceived qualities, implying optimal visual experiences can be achieved without resorting to high illuminance or luminance levels, thus offering potential energy-saving opportunities. The results also highlighted the interconnectedness of visual attributes, such as increased visual interest with visual clarity and colorfulness. Linear regression analysis leads to a computational model with a low predictive power, which highlights the challenges of developing an accurate model of visual perception.</p>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 7","pages":"815-832"},"PeriodicalIF":2.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsid.2042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144673037","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}

It is inferred that the weak interstitial oxygen bonds near the drain region would be easily broken by the impact of hot carriers. Thus, the acceptor-like interstitial oxygen trap states are generated, leading to the aggravated deterioration of DCD.

During the usage, stray light has been treated as a pivotal factor affecting the image display quality of this waveguide structure, leading to image ghosting or flipping problems. In this paper, we propose a stray-light-free waveguide near-eye display using a pin-mirror array and multiple thin plates. A two-step optimization method has been used to eliminate stray light. Firstly, the effects of the parameters of near-eye displays have been investigated, such as eye relief, pin-mirror size, and spacing size; further, the position and range of total reflection on the front and rear surfaces of the waveguide for the residual stray light are quantitatively analyzed. According to the position and range of the total reflection, multiple thin plates can be introduced to optimize the stray-light paths. To minimize the proportion of stray light in the eye box, the thickness and height of the plates can be optimized. Finally, a compact waveguide near-eye display with stray-light ratio below 0.1% across the eye box is obtained, which can effectively improve the display quality of virtual image. To verify the effectiveness of the method, image simulation was performed, and the results are consistent with the analysis. This method can also improve the vertical FOV while eliminating the stray light, which is very helpful to improve the performance of this kind of waveguide structure.</p>","PeriodicalId":49979,"journal":{"name":"Journal of the Society for Information Display","volume":"33 6","pages":"746-757"},"PeriodicalIF":2.2,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635464","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 sensitivity of perceived image quality to parallax variation was lower than other parameters. To be specific, an excessive increase in the depth led to the reduced perceived image quality and visual comfort due to the occurrence of 3D artifacts, which becomes a problem to be solved.
