CLEARink Displays Corporation is a Vancouver technology start-up developing new display technology. Theirtechnology is an alternative to liquid crystal displays and organic light emitting diodes which operate withsignificant power consumption. CLEARink has developed a novel reflective display technology that offersvideo rate capability with ultra-low power consumption. Their technology is based on the use of chargedparticles in a fluid to control the reflectivity of ambient light from its novel reflector films. When chargedparticles are in the vicinity of the reflector film, reflectivity is hindered, providing image contrast. Control overof the charged particle location is achieved by applying small voltages to thin conductor and dielectric layers inthe display device stack. Fine control of particle location and mobility in response to the applied fields iscritical 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 andtheir connection to display performance. The fabrication and characterization capabilities available at SFU's 4DLABS in conjunction with our expertise in surface science and materials chemistry make this new partnershipwith CLEARink ideal. Using scanning electron microscopy, x-ray diffraction and atomic force microscopy, thequality of dielectric layers will be assessed in relation to device performance. Working closely with CLEARinktechnical staff, we will also investigate device performance with dielectric films deposited by differentmethods, and where dielectric films have been further modified through additional barrier layers deposited byphysical and chemical methods. The expected outcomes of this project are to provide CLEARink withimproved control over their display characteristics and to accelerate their path to commercial production. Thiswill provide broader benefits to Canada through enhanced employment opportunities, wealth generation, andpave the way for further high technology development opportunities.

Clearink Display Corporation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运行能耗很高。Clearink开发了一种新的反射式显示技术，可提供超低功耗的视频速率能力。他们的技术是基于在流体中使用带电粒子来控制来自其新型反射膜的环境光的反射率。当带电粒子在反射膜附近时，反射率会受到阻碍，从而提供图像对比度。通过向显示器件堆叠中的薄导体和介质层施加小电压来实现对带电粒子位置的过度控制。对粒子位置和迁移率的精细控制对显示性能至关重要，但会受到导体和介质层的属性的影响。Clearink正在寻求进一步优化这种控制，以改善对比度和器件响应时间。在此，我们建议通过检查介质薄膜的材料属性及其与显示性能的关系来解决这些问题。SFU的4DLABS提供的制造和表征能力，再加上我们在表面科学和材料化学方面的专业知识，使我们与Clearink的这种新的合作伙伴关系成为理想的选择。使用扫描电子显微镜、X射线衍射和原子力显微镜，将根据器件性能来评估介质层的质量。我们还将与CLEARINK技术人员密切合作，研究用不同方法沉积的介电薄膜的器件性能，以及通过物理和化学方法沉积的额外阻挡层对介电薄膜进行进一步改性的情况。该项目的预期结果是为CLEARink提供对其显示特性的改进控制，并加快其商业化生产的速度。这将通过增加就业机会和创造财富为加拿大带来更广泛的好处，并为进一步的高科技发展机会铺平道路。
