Title: Michael Geoffrey Pitt: Innovator in Electrophoretic and Liquid Crystal Display Technologies

Introduction

Michael Geoffrey Pitt is a notable inventor based in Heerlen, Netherlands. He has made significant contributions to the field of display technologies, holding a total of three patents. His work primarily focuses on electrophoretic display devices and liquid crystal display devices.

Latest Patents

One of his latest patents is for an electrophoretic display device and driving means for restoring the brightness level. This invention comprises a pixel with an electrophoretic medium and electrodes, along with drive means that allow the pixels to be brought into different optical states. After the application of an addressing pulse for setting the brightness level of a pixel, a restore pulse voltage is applied to restore the brightness level to the set level. This restore pulse may consist of consecutive pulses to bring the brightness level back to its original state more smoothly.

Another significant patent involves a liquid crystal display device with reflective material that hides switching material. This method of manufacturing a liquid crystal device includes a layer with a fixed cholesteric order. The patterned layer is created by providing a layer of polymerizable cholesterically ordered material and a compound that can be converted by radiation. The pitch of the cholesterically ordered material is influenced by the compound in its converted state, leading to regions of different pitch after irradiation and polymerization.
