Title: The Innovations of Patrick M Dunn
Introduction
Patrick M Dunn is a notable inventor based in Coral Springs, FL (US). He has made significant contributions to the field of display technology, holding a total of 9 patents. His work primarily focuses on methods and systems for enhancing liquid crystal displays (LCDs).
Latest Patents
One of his latest patents is a method for multiplex driving a passive liquid crystal display (LCD). This innovative method produces a plurality of bi-level waveforms on the ROW/common lines and COLUMN/segment lines of a passive multiplexed LCD. The waveforms drive the LCD display using binary data from display memory locations. At periodic intervals, a counter is incremented, and its value is used to look up bi-level data for output on the ROW/commons, memory locations for active COLUMN/segments, and to provide inverted COLUMN/segments data before sending the bi-level data to the COLUMN/segment lines of the LCD. The counter increments from zero to four times the number of ROW/commons before being reset, allowing the waveforms to repeat. This algorithm produces one ON/select voltage and one OFF/non-select voltage for the LCD.
Another significant patent is for an active matrix display. This flat panel display utilizes active matrix addressing with two parallel substrates that contain an organic electroluminescent medium. This medium emits visible light in response to an electrical signal, and the top substrate is transparent to allow the emitted light to be visible. The bottom substrate does not need to be transparent, as the active matrix display operates in either emissive or reflective mode. An array of electrodes is situated on the inside face of the bottom substrate, while a corresponding transparent electrode is located on the inside face of the top substrate. This configuration defines an array of pixels, with switches located on the backside of the bottom substrate connected to respective electrodes.
