International Classification:

C07D 333/74

US Classification:

549 41

Abstract:

Compounds containing bibenzochalcogenophene structures are provided in which the chalcogenide is sulfur, selenium, or tellurium. The compounds are characterized by planarity, rigid conjugation structure and high charge mobility making them useful as organic semiconductor in optical devices, electronic devices and integrated devices like organic field effect transistors (OFET) for thin film transistor liquid crystal display (LCD), electrophoretic display such as electronic paper, organic light emitting diode (OLED) for flat panel displays, organic radio frequency identification (ORFID) tags, organic photovoltaic (OPV), sensor devices, and analog and digital electronics.

International Classification:

H01J 146
H01J 102

US Classification:

313308

Abstract:

A method for forming a field emission flat panel display includes deposit a conductive patterned layer on a substrate, depositing an emitter material over the patterned layer, patterning the emitter material to provide a series of mask caps, etching the emitter material to provide arrays of emitter peaks with the mask caps thereon, depositing a dielective layer on the patterned layer and on the mask caps, depositing a conductive gate layer on the dielectric layer, depositing a high-resistivity dielectric layer on the gate layer, depositing a low-resistivity dielectric layer on the high-resistivity dielectric layer, and etching away portions of the dielectric layer, gate layer, high-resistivity dielectric layer and low-resistivity dielectric layer to expose the mask caps, and removing the mask caps to expose the emitter peaks to provide an emitter cathode panel, providing a transparent panel having a conductive coating thereon, and depositing a layer of thin film phosphors on the conductive coating to provide an anode screen, and attaching the anode screen to the cathode panel.
