Title: Innovations of Gerald T Harder
Introduction
Gerald T Harder is a notable inventor based in Gilbert, AZ (US). He has made significant contributions to the field of liquid crystal display technology. With a total of 3 patents, his work focuses on power-saving methods and integrated circuits.
Latest Patents
One of his latest patents is a power-saving circuit and method for driving liquid crystal displays. This invention includes a power-saving column driver integrated circuit that utilizes a series of multiplexers. These multiplexers are coupled to the columns of the display, selectively connecting each column to a common external storage capacitor during specific portions of the row drive period. This process discharges each pixel in the selected row to a median bias voltage. During the remaining portion of the row drive period, the multiplexers connect voltage drivers to the columns of the LCD pixel array, applying the desired driving voltage. The polarity of the driving voltages alternates on succeeding row drive periods, resulting in a voltage that averages to the median bias voltage on the storage capacitor. For active matrix liquid crystal display panels, a multiplexer connects the backplane of the display panel to either an external storage capacitor or an alternating-polarity backplane driving voltage during each row drive period.
