Title: Innovations by Bhadrinarayana L Visweswaran
Introduction
Bhadrinarayana L Visweswaran is an accomplished inventor based in Santa Clara, CA. He has made significant contributions to the field of display technology, holding 2 patents that showcase his innovative approach to enhancing display devices.
Latest Patents
One of his latest patents focuses on applying gain and offset correction factors for pixel uniformity compensation in display panels. This invention involves a processor that receives image data, including gray level data and display brightness value (DBV) data for a pixel. The processor determines gain and offset compensation factors based on a correction spatial map and a brightness adaptation lookup table (LUT). It then generates compensated gray level data to improve the pixel's performance.
Another notable patent by Visweswaran is related to encapsulation layers with improved reliability. This invention describes an electronic device featuring a display with an array of organic light-emitting diodes (OLEDs) protected by an encapsulation layer. The layer consists of a transparent sheet interposed between upper and lower inorganic films, which are divided into multiple sub-layers to enhance reliability. Additional moisture protection is provided by a conformal thin-film coating, such as an aluminum oxide layer formed using atomic layer deposition techniques.
