Latest Patents

Among his latest patents is a technology titled "Displays controlled by MIM switches of small capacitance." This invention involves a matrix multiplexed field effect display that utilizes switch devices at matrix crosspoints to establish a turn-on threshold for the field effect material. The switch devices are thin film metal-insulator-metal (MIM) switches, which allow the display to operate at low current, ensuring that the MIM switches, potentially deposited on glass, do not degrade rapidly during use. Another significant patent is the "Addressing scheme for switch controlled liquid crystal displays." This innovation addresses the transient behavior of switches controlling matrix multiplexed liquid crystal displays (LCDs). By applying a series of unipolar pulses followed by corresponding pulses of opposite polarity, the invention ensures that selected pels are fully turned on while maintaining a net DC current of zero to prevent irreversible electrochemical degradation of the liquid crystal.
