Title: The Innovations of Paul M Alt
Introduction
Paul M Alt is a notable inventor based in Yorktown Heights, NY (US). He has made significant contributions to the field of display technology, holding a total of 4 patents. His work primarily focuses on enhancing the efficiency and reliability of thin film transistor (TFT) liquid crystal displays (LCDs).
Latest Patents
One of his latest patents is titled "TFT LCD Active Data Line Repair." This invention presents a matrix addressed display system that enables efficient and low-cost data line repair through electronic mechanisms, ultimately increasing yield. The active data line repair utilizes additional data driver outputs, a defect map memory in the TFT/LCD module, and modifications to the data stream by additional circuits between the display and the display adapter. The design incorporates a bus configuration on the display substrate that combines repair flexibility, low parasitic capacitance, and the ability to make necessary interconnections easily. The number of interconnections is minimized, ensuring reliability, and these connections can be made using conventional wire bond, laser bond, or disk bond technology.
Another significant patent is the "Method for Eliminating Crosstalk in a Thin Film Transistor/Liquid Crystal Display." This innovation addresses the issue of crosstalk between data lines and pixel cells in TFT/LCDs. It achieves this by applying a data signal to a specific data line for a duration shorter than the standard scan line period of the display, followed by a crosstalk compensation signal for the remainder of the scan line period.
