Latest Patents

One of Xiangtong Li's latest patents is titled "Electronic devices having antiglare films with transparent apertures." This invention involves an electronic device equipped with a display that is overlapped by an antiglare film. The film features a rough surface to diffuse incident light, effectively reducing glare. Additionally, it includes a smooth portion that forms a transparent window, allowing light to pass through undiffused. This design enables light-based components, such as cameras, to receive undiffused light, facilitating more accurate measurements. The display may also incorporate various layers, such as opaque masking layers or polarizers, with openings aligned with the transparent window to optimize light reception.

Another notable patent is "Displays with direct-lit backlight units." This invention describes a display where an array of pixels is illuminated by a backlight consisting of light-emitting diodes arranged in respective cells. A reflector is utilized to direct light from the diodes through the pixel array. The reflector's cross-sectional profiles are designed to distribute light effectively toward the edges of the cells. Furthermore, a light diffuser layer may include a partially reflective layer, such as a thin-film interference filter, which enhances the display's performance.
