Title: Innovations of James C Greeson, Jr.

Introduction

James C Greeson, Jr. is a notable inventor based in Woodstock, NY (US). He has made significant contributions to the field of thin film transistor liquid crystal display technology. With a total of 5 patents to his name, Greeson has demonstrated a commitment to innovation and advancement in display technologies.

Latest Patents

Greeson's latest patents include a TFT LCD device having a color filter layer decal. This invention employs decal technology to provide a color filter layer for a thin film transistor liquid crystal display device. The red, green, and blue color regions, along with an opaque surround, are printed on a suitable substrate using gravure printing techniques and colored glass frit materials. Once the printed decal is transferred to one of the glass panels, it can be heated to fuse it to the glass. Electrodes can then be deposited directly on this fused color filter layer.

Another significant patent is for a TFT LCD display having polychromatic glass color filters. This invention provides the color filters required for a thin film transistor liquid crystal display device by using polychromatic glass for either the front or rear glass panel. Through a series of masking, ultraviolet exposure, and heat treating steps, red, green, and blue color areas can be generated in the polychromatic glass. Each of the different colored areas is aligned with one of the individually-addressable pel electrodes in the device.
