Lai Fan LAI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11003290
    Abstract: A flexible transparent sensing film with embedded electrodes is described in the present invention, which would greatly improve the optical transmittance, electrical conductivity and reliability. The present sensing film can also simultaneously enable multiple touches for distinct locations sensing and at least another set of electrical signal sensing. The present sensing film includes a top conductive electrode, a bottom conductive electrode (140) and a dielectric substrate or a functional substrate that would generate electrical signal response due to a specific input such as motion, light, chemical, or temperature. The present sensing film apparatus could be configured to have the top and bottom conductive electrodes which are partially or fully embedded onto the surfaces of the dielectric and/or functional substrates.
    Type: Grant

  • Patent number: 10329660
    Abstract: The present invention provides a transparent conductive thin film which is flexible for suiting substantially all kinds of electronic and optoelectronic devices or display panel. The present conductive thin film includes at least one transparent substrate, a deformable layer and a conductive network pattern having a high aspect ratio such that at least one surface of the conductive network being exposed out of the deformable layer or the transparent substrate for contacting with an external structure while a large proportion thereof stays firmly integrated into the substrate. The present invention also relates to methods of fabricating a transparent conductive thin film including the structural features of the transparent conductive thin film of the present invention. Various optimizations of the present methods are also provided in the present invention for facilitating large area thin film fabrication and large scale production.
