P.128 - An Auxiliary Diagnostic Method of Brain Atrophy Based on MRI Images
  • Ziyang Ruan, Bo Cheng, Chenhong Li
    South Central Minzu University Wuhan China


  • Brain atrophy is a structural change in the cerebral cortex, which is detected by means of imaging and clinically diagnosed by a doctor who reads the films. To solve the problem of automatic diagnosis of brain atrophy, a method of automatic segmentation of brain atrophy regions is designed. Under the condition of no human intervention, the widened sulcus region produced by brain atrophy in MRI images is automatically analyzed, and by calculating the ratio of the atrophied region of the posterior sulcus to the brain tissue, it is judged whether the patient has brain atrophy or not. Compared with a traditional diagnosis by reading the film, it is more efficient and clearer, and the degree of brain atrophy is quantified parametrically, which has practical application value.
P.129 - Black Spot Phenomenon and Improvement in QLED Devices
  • Fengjie Jin, Yuanming Zhang, Xiang Liu

  • Liang Su, Zhimin Yan, Fuxing Jiao
    Kunshan Govisionox Optoelectronics Co., Ltd. Kunshan China


  • The authors study the influence of the electron transporting layer (ETL) and cathode material type as well as their interface on the performance of quantum-dot light-emitting devices (QLEDs). Through their research, the authors find that the black spot phenomenon in QLED devices is strongly related to ETL material, and the number of black spots can be greatly reduced by improving ETL. In addition, the cathode material, such as Ag and Al, has an impact on black spots. Finally, one novel double-layer ETL structure device is developed to avoid black spots, which shows that the interaction between ETL and the electrode interface also plays an important role. The absence of black spots in inverted devices also proves this conclusion.

  • Using displays such as a smartphone, in-car TV, or even fusion information on the side windows of a moving vehicle may cause motion sickness. A visual-based pre-alert method is presented to solve the issue and an MSSQ method is applied to judge the sickness degree. A human factor experiment has been accomplished to show the effectiveness of the proposed method.
P.133 - Quantum Rod-Based Truly Random Number Generator (QR-TRNG)
  • Bibarys Mnaidar, Vigneshwaran Swaminathan, Debjyoti Bhadra, Jianxin Song, Maksym Prodanov, Abhishek Srivastava
    Hong Kong University of Science and Technology Hong Kong Hong Kong


  • A novel technology is proposed as a quantum rod-based truly random number generator. The objective is to construct a device array by stacking together five layers: 1) backlight unit; 2) thin-film transistor liquid-crystal display; 3) quarter waveplate; 4) and 5) quantum-rod films, red and green, respectively, aligned uniformly in-plane yet orthogonally to each other. QR's anisotropic absorption nature plays a key role in generating four different pixel outputs: 0 - pixel is off; 1 - excited pixel is predominantly green; 2 - yellowish; 3 - red. Further, TRNG is enabled by rotating excitation polarization direction
P.134 - Organic Buffer Layer Depresses Dark Current of Short-Wave Infrared PbS Quantum-Dot Photodetector

  • The incorporation of an organic buffer layer has proven effective in suppressing dark current in short-wave infrared PbS quantum-dot photodetectors. This innovative approach involves strategically depositing an organic material between the active PbS quantum dots and the electrode interface. The organic buffer layer acts as a barrier, mitigating charge carrier recombination and leakage, resulting in a substantial reduction in dark current. This breakthrough enhances the signal-to-noise ratio and overall device performance, showcasing its potential for improving the sensitivity and responsivity of short-wave infrared photodetectors with diverse applications in night vision and telecommunications.
P.135 - Toward Passing the Visual Turing Test with Field-of-Light Displays
  • Nicholas Wells, Amilcar Soares, Matthew Hamilton
    Memorial University St. John's NF Canada


  • Field-of-light displays (FoLDs) promise to allow further increase in realism beyond the limits of conventional 2D displays. While the question of how a conventional display can match the limits of the human visual system has been answered, the same question applied to FoLDs has been given much less attention. In this work, the authors review a recent acuity-limited viewer model of resolution at depth for a FoLD display. They validate this model using display simulation. They discuss how this model gives fewer conservative resolution guidelines than previous models, presenting resolution requirements for passing the visual Turing test.

  • In this study, the periodic nanostructures of various shapes are fabricated using a low-cost, low-power continuous wave laser. The nanostructures can be easily fabricated with a low-cost, simple process using a laser interference lithography technology. In addition, the authors demonstrate that various shapes such as spherical, hemispherical, and wavy shapes can be easily controlled by adjusting the surface energy of the substrate and process parameters.
P.245 Late-News Poster: High Ambient Contrast Ratio Transparent Front-Projection Film
  • Fung Hsu Wu, Chen-Kuan Kuo
    BenQ Materials Corp. Taoyuan Taiwan Roc


  • Transparent displays are realized by various approaches such as LCD, microLED display, OLED display, etc. The authors propose a high-image-quality transparent projection display in this paper. The projection film for such a display is composed of a micro-replication base film with an ambient light-reduction layer (absorptive black ink) to enhance the image qualities in the ambient condition. The ambient light is guided by a microlens to light-reduction material and thus enhances the contrast ratio of the image in the bright environment. A portion of the projection screen, an area of about 40%, is left blank intentionally for see-through purposes. Such a projection film increases the image contrast ratio ideally by 5 times compared to traditional matte-white projection screens. The projection film is proposed for see-through scenarios such as automobile entertainment or retail applications.
