CLEARink Displays Corporation is a Vancouver technology start-up developing new display technology. Their**technology is an alternative to liquid crystal displays and organic light emitting diodes which operate with**significant power consumption. CLEARink has developed a novel reflective display technology that offers**video rate capability with ultra-low power consumption. Their technology is based on the use of charged**particles in a fluid to control the reflectivity of ambient light from its novel reflector films. When charged**particles are in the vicinity of the reflector film, reflectivity is hindered, providing image contrast. Control over**of the charged particle location is achieved by applying small voltages to thin conductor and dielectric layers**deposited onto their proprietary reflectors. Fine control of particle location and mobility in response to the**applied fields is critical for display performance, but can be affected by the properties of the conductor and**dielectric layers. CLEARink is seeking to further optimize this control in order to improve contrast, and device**response time. Here, we propose to address these issues by examining the materials properties of the dielectric**thin films and their connection to display performance. The fabrication and characterization capabilities**available at SFU's 4D LABS in conjunction with our expertise in surface science and materials chemistry make**this partnership with CLEARink ideal. Using scanning electron microscopy, x-ray diffraction, x-ray**photoelectron spectroscopy, atomic force microscopy, and contact angle measurements, the quality of dielectric**layers will be assessed in relation to device performance. Working closely with CLEARink technical staff, we**will investigate device performance with dielectric films of different thickness, and where the dielectric films**have been further modified through further chemical modification. The expected outcomes of this project are to**provide CLEARink with improved control over their display characteristics and to accelerate their path to**commercial production. This will provide broader benefits to Canada through enhanced employment**opportunities, wealth generation, and pave the way for further high technology development opportunities.

CLEARink显示器公司是一家温哥华技术初创公司，开发新的显示技术。他们的技术是液晶显示器和有机发光二极管的替代品，这些显示器和有机发光二极管的工作功耗很大。CLEARink开发了一种新颖的反射式显示技术，以超低功耗提供 ** 视频速率能力。他们的技术是基于使用流体中的带电粒子来控制其新型反射膜对环境光的反射率。当带电 ** 粒子在反射膜附近时，反射率被阻碍，提供图像对比度。对带电粒子位置 ** 的控制是通过向沉积在其专有反射器上的薄导体和介电层 ** 施加小电压来实现的。响应于施加的场而对颗粒位置和迁移率的精细控制对于显示器性能是至关重要的，但是可能受到导体和介电层的性质的影响。CLEARink正在寻求进一步优化这种控制，以提高对比度和设备 ** 响应时间。在这里，我们建议通过检查介电薄膜的材料特性及其与显示性能的关系来解决这些问题。SFU 4D实验室的制造和表征能力 ** 与我们在表面科学和材料化学方面的专业知识相结合，使 ** 与CLEARink的合作成为理想的选择。使用扫描电子显微镜、X射线衍射、X射线光电子能谱、原子力显微镜和接触角测量，将评估介电层的质量与器件性能的关系。我们将与CLEARink技术人员密切合作，研究不同厚度的电介质薄膜的器件性能，以及电介质薄膜 ** 通过进一步的化学改性进行进一步改性的情况。该项目的预期成果是 ** 使CLEARink能够更好地控制其显示特性，并加快其商业化生产的进程。这将通过增加就业机会、创造财富为加拿大带来更广泛的利益，并为进一步的高科技发展机会铺平道路。
