Title: Innovations by Pubudu Thilanka Galwaduge
Introduction
Pubudu Thilanka Galwaduge is an accomplished inventor based in Fremont, CA. He has made significant contributions to the field of light-collimating technologies, holding a total of 3 patents. His work focuses on enhancing the functionality of display technologies, particularly in providing privacy and control over light direction.
Latest Patents
One of his latest patents is titled "Switchable light-collimating layer with reflector." This invention describes a method for collimating light using a film that includes elongated chambers filled with bistable electrophoretic fluids. The light-collimating films developed by Galwaduge are designed to control the amount and direction of light that passes through a transmissive substrate. These films can be integrated into devices such as LCD displays, allowing users to create a zone of privacy while viewing the screen. The switchable nature of the film enables users to adjust the collimation of emitted light on demand. Importantly, because the films are bistable, they do not require additional power once they have been switched to a display state.
Another notable patent is "Driving waveforms for switchable light-collimating layer including bistable electrophoretic fluid." This patent outlines methods and controllers for driving the light-collimating film, which also utilizes elongated chambers of bistable electrophoretic fluids. Similar to his previous invention, this technology is aimed at controlling light direction and amount, enhancing user experience in devices like LCD displays.
