Title: Tsae-Pyng Janice Shen: Innovator in Liquid Crystal Display Technology
Introduction
Tsae-Pyng Janice Shen is a prominent inventor based in Thousand Oaks, CA (US). She has made significant contributions to the field of liquid crystal display (LCD) technology, holding a total of 4 patents. Her innovative work focuses on improving the perceptual quality of images displayed on LCDs.
Latest Patents
One of her latest patents is titled "Image coding for liquid crystal displays." This invention utilizes a source coder that exploits the spatial and temporal masking properties of an LCD flat panel display. It aims to enhance the perceptual quality over a limited bandwidth channel. The black matrix of the LCD generates a strong noise component centered at the Nyquist frequency, which masks parts of the signal spectrum. Additionally, the sluggish response times of liquid crystals create a temporal mask that reduces the spatial resolution of moving objects. To address these challenges, the source coder shifts bits from masked transform coefficients to unmasked coefficients, thereby improving the perceived visual quality of the reconstructed image. The image coder can also be designed to match the color depth associated with the LCD.
Another notable patent is the "Method and apparatus for driving a liquid crystal display." This invention provides a method and apparatus for driving a passive liquid crystal display to achieve a high contrast ratio for both still images and video modes. It includes driving some or all of the row lines simultaneously, with row voltage waveforms defined as a set of orthogonal functions. The column voltage waveforms are defined as a linear combination of the row voltages. The mean square voltage across each pixel and row is specified, and the corresponding column coefficient is calculated, allowing for the determination of all coefficients in a column.
