However, developing high-efficiency QRLEDs faces several challenges, such as low quantum yield of the QRs and charge imbalance in the device. Recent advancements in QRLEDs have achieved an EQE of 22%, and the study focuses on red QRs only. Expanding QRLEDs for full-color displays is essential for producing highly efficient green QRs. In this work, we synthesized highly efficient green CdSe/Cd<sub>x</sub>Zn<sub>1-x</sub>S QRs at an emission wavelength of 518 nm, achieving a quantum yield of over 95%. We identified two pathways of electron leakage in QRLEDs at the organic/inorganic interface, ultimately limiting the device's efficiency. We improved the device efficiency by mitigating electron leakage and enhancing hole injection in QRLEDs using multi-stacked HTLs.

This paper extends the EQE equation and implements a LEE secondary optics factor (the secondary optics of light extraction efficiency). We consider four different optical effects on micro-LED displays, including refraction, reflection, black matrix, and focusing. The main purpose of this paper is to study how to enhance the display-level light extraction and LEE secondary optics parameters under different conditions. We conduct optical simulations for three different LED sizes and various structures, including glue, black matrix, white glue, and microlens array. Comparing the simulation results with real experiment results, our findings show that a combination of black and white glue structures resulted in a 20% enhancement in efficiency compared to using black glue alone.

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.

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.
