Title: The Innovations of Gary Parrett
Introduction
Gary Parrett is a notable inventor based in Rochester, NY (US), recognized for his contributions to the field of electroluminescent displays. With a total of 12 patents to his name, Parrett has made significant advancements in display technology, particularly in compensating for initial nonuniformity in electroluminescent panels.
Latest Patents
Among his latest patents is the "Electroluminescent display initial-nonuniformity-compensated drive signal." This invention addresses the issue of initial nonuniformity, commonly referred to as 'mura,' in electroluminescent (EL) panels with 2T1C subpixels. The technology involves measuring the current of each subpixel at a selected time to generate a status signal that reflects the characteristics of the subpixel. A compensator then adjusts the linear code value based on these status signals, allowing for improved performance of the display.
Another significant patent is the "Compensated drive signal for electroluminescent display." This innovation compensates for initial nonuniformity or aging of drive transistors and EL emitters in 3T1C EL subpixels, such as those found in organic light-emitting diode (OLED) displays. The invention utilizes a readout transistor connected to the EL emitter to measure the voltage of the emitter, allowing for compensation of variations in voltage and OLED efficiency loss. This process is performed individually for each subpixel, enhancing the overall display quality.
