With the rapid development of digital and intelligent information systems, the display of visual information on interfaces has become an important challenge in the field of human-computer interaction, as well as the human-computer interface of nuclear power plants. This paper examines effective factors affecting visual attention capture based on icons related to the human-computer interface of nuclear power plants. Experiments were conducted on multiple factors of visual search tasks with reference to information features to analyze information display factors affecting visual cognitive performance. The experimental results showed that the three factors, icon shape, feature display, and target position, have a great effect on information searching performance. The main effect of reaction time on three factors all reached a significance level congruent with the effect on fixation time and pupil response. Eye gaze indexes of feature display factors presented an increasing trend, which indicates that the information block spends more time on cognitive processing than icon features in the human-computer interface of nuclear power plants. Pupil diameter was dilated when searching icons under difficult visual cognition conditions, and when searching information blocks, pupils were dilated more than searching single icons. Therefore, shape highlighting of data icons in the human-computer interface of nuclear power plants can effectively improve the attention capture of the operator's visual search, and the ease of icon discrimination is an influential factor in visual attention capture.

In this paper, we propose a modified architecture aimed at reducing the computational demands of the generative adversarial network for super-resolution image generation. To achieve this, we embedded depth-wise and point-wise convolution into the convolution layer, effectively decreasing operational complexity and improving the overall network structure. For training and validation, we utilized a dataset consisting of 900 image pairs with resolutions of 480 × 270 and 1920 × 1080. Our experimental results demonstrated that the proposed method can reduce computational operators by 63% compared to the original network, while still maintaining the quality of super-resolution images. To enable real-time implementation, the architecture with light model subsequently deployed it on a GPU processor, allowing for efficient scaling of TV signals for 16× resolution expansion. Our experiments showed that the peak signal-to-noise ratio (PSNR) reached approximately 28 dB, and the processing rate ranged from 6 to 14 frames per second. The network effectively produced output with 16 times greater resolution without introducing any blurring and obvious artifact.

The representation of images on autostereoscopic 3D display often suffers from visual fatigue induced by stereoscopic images (VFSI) and visually induced motion sickness (VIMS), deriving from conflict between accommodation and convergence and from mismatches between vestibule system and visual system of viewers, respectively. In this study, a subjective experiment was conducted to investigate the implications of age and gender on the visual discomfort when watching the 3D video clips with four levels of parallax on autostereoscopic 3D display. This study found that the age of observers significantly affected both VFSI and VIMS symptoms. The young observers reported more serious VFSI and VIMS symptoms than the middle and elderly, while the three age groups had significantly pairwise difference for VIMS symptoms. Although gender differences did not exist in the ratio of VFSI symptoms, females had significant higher VIMS scores than males. The effect of parallax on symptom scores varied with age and gender. The elderly and male observers could endure larger parallax when compared to other groups. Furthermore, considering viewing safety for observers, it is recommended to limit parallax to a threshold of 40′.

Virtual-real fusion (VRF) technology plays a crucial role in the meta-universe by bridging the gap between virtual environments (VEs) and physical environments (PEs). However, the current VRF system has the problem of single function and fixed integration, limiting the popularization and application of VRF technology. Therefore, this paper proposes a framework named synchronous mixed reality (SMR) to personalize the VRF system and maintain the balance between interaction efficiency and environmental immersion. We combine an instance segmentation algorithm with an interaction prediction algorithm to achieve this balance. To evaluate the effectiveness of the SMR framework, we design three scenarios based on the interaction properties of physical objects and measure environmental immersion, systematic interaction efficiency, and user experience. Our results demonstrate that the SMR framework meets diverse needs in various PEs while balancing immersion and interaction efficiency. Additionally, our framework significantly reduces collisions and negative emotions experienced by users in VEs. We anticipate that this framework will serve as a guide for constructing virtual-real fusion systems in the future.

We clarified that a ferroelectric liquid crystal (FLC) has high resolution display capability as small as 1 × 1 μm pixel pitch using an FLC pixel array with a two-layer electrode, which has a 1 × 1-μm-checkered apertured electrode and a plane electrode separated by an insulation layer. By applying +2 V to the apertured electrode and −10 V to the plane electrode in the two-layer electrode and 0 V to the transparent common electrode, a checkered pattern was clearly observed, which indicates the successful individual pixel driving with a pixel pitch of 1 × 1 μm. When fabricating 1 × 2-μm-pitch rectangular FLC pixels, we elucidated that the liquid crystal alignment direction should be along the shorter side of the pixels to avoid asymmetric transmittance distribution in each pixel. Moreover, we successfully reconstructed a 3D holographic image using 10 × 10 k FLC pixel array with a pitch of 1 × 1 μm driven by the two-layer electrode with hologram-patterned apertures. We showed that FLC is a strong candidate material for realizing spatial light modulator with extremely small pixel pitches, which is essential for holographic displays with wide-viewing-zone angles.

We present a focal surface projection to solve the narrow depth-of-field problem in projection mapping applications. We apply a phase-only spatial light modulator to realize nonuniform focusing distances, whereby the projected contents appear focused on a surface with considerable depth variations. The feasibility of the proposed technique was validated through a physical experiment.

Electronic paper (e-paper) is a reflective display technology with unique advantages, such as bistability, low-power consumption, and high ambient contrast ratio. These features make e-paper a promising candidate for future Internet of Things applications. Among different technologies of e-paper, electrophoretic display (EPD) is the most successful one for commercialization. However, the edge ghosting (also known as the fringing effect) still limits the performance of EPD. Herein, we established a model of particle dynamics of electrophoresis, simulated the edge ghosting of microcapsule EPD, analyzed the edge ghosting effect, and revealed the relationship between thicknesses, dielectric constants of the back binder layer, and the edge ghosting. Two EPD panels with different thicknesses of back binder layer were demonstrated, which verifies the accuracy of this simulation model. With the proposed model, many device mechanisms and product issues can be analyzed and illustrated, which is supposed to guide the researchers in optimizing the device structure design of EPD.

In this article, novel n-FFS liquid crystal material from Slichem was used in order to elevate the anti-backlight long aging effect; a trace amount of free radical trap HALS-like additive was added, the principle of which can be expressed via Denisov cycle, confirmed by measuring the temporal VHR changes in test cells; three different resolution (FHD ~ QHD) models paired with N19 and N21 were selected for testing by comparing the actual panel. It is verified that the optimized material greatly improves the image sticking performance of the panel and keeping optical performance.

We report a 0.39-in. quantum dot light-emitting diode (QLED) microdisplay with full high-definition (FHD, 1920 × 1080) resolution by integrating a red top-emitting QLED on a complementary metal–oxide–semiconductor (CMOS) backplane. By optimizing the microcavity structure and constructing a suitable energy-level structure for the QLED devices, the performance of the large-area (4.9 × 8.7 mm²) top-emitting device with normal structure reached 13,936 cd/m² of brightness at 5-V bias with 13.3% external quantum efficiency (EQE). Notably, the optimal device showed a low turn-on voltage of 1.7 V, which matched well the voltage output of the CMOS backplane. Our work demonstrates the great promise of QLED microdisplays for applications in head-mounted augmented reality/virtual reality (AR/VR).

A set of direct current (DC) analytical equations is formulated for the analysis and design of a single-layer thin-film transistor (TFT). For a specified TFT structure, drain current is calculated as a function of drain and gate voltage (taking the source as ground) according to the Enz, Krummenacher, Vittoz (EKV) compact model. One model parameter function is required to implement this EKV-based equation, that is, drift mobility as a function of gate voltage. Drift mobility is evaluated as a consequence of accumulation layer electrostatics assessment of the TFT structure specified. In order to implement the model, three semiconductor properties (low-frequency (static) relative dielectric constant, free electron concentration, and maximum (no trapping) mobility), two structure properties (insulator capacitance density and TFT width-to-length ratio), and one physical operating parameter (temperature) must be specified. Optimal TFT mobility performance is achieved when the thickness of the semiconductor channel layer is constrained to be less than 2.22 times the channel layer Debye length such that “short-base” TFT operation obtains. Additionally, higher mobility TFT performance is obtained by selecting a channel layer with a small electron effective mass, reducing channel layer trap density, reducing channel layer thickness, reducing the free electron concentration, and/or increasing gate capacitance density.
