Abstract: An active matrix current source controlled gray level tunable FED. The inventive FED uses active devices to convert a voltage-controlled signal into an output current and a capacitor to record and hold the voltage-controlled signal, thereby producing a low control voltage and active current source driving FED. As such, adjustment and maintenance of the gray level brightness of the FED is achieved because the brightness fixed by the active devices and the capacitor can obtain a high transient brightness when the FED operates in a lower voltage and brightness, thereby producing a high average brightness and avoiding an arc from high-voltage operation or poor vacuum.

Abstract: An improved FED driving method, which uses a voltage control different from the prior FED, to turn an electron beam on/off and increase the resolution. The improved FED driving method is characterized in increasing a positive voltage applied to the FED's anode, grounding the FED's emitter and applying a negative voltage to the FED's gate. When driving the FED, the anode can pull electron beam out of the cathode with high accelerate voltage and the applied negative voltage on the gate can turn the electron beam on/off. As such, this allows a higher resolution because the electron beam is not influenced by the gate's lateral attraction and high lighting efficiency with high anode accelerate voltage.

According to above method, the capacity is substantially increased without extending the original bottom area of the capacitor electrode by using the surface area of the nanotube, nanowire, or nanobelt as the area of the capacitor electrode.

Abstract: A field emission display panel device that incorporates carbon nanotube emitter layers for emitting electrons wherein the carbon nanotube layers has a smaller width than the conductive paste layers it is deposited on is disclosed. The width of the carbon nanotube layer should be less than ¾ of the width of the conductive paste layer, or in a range between about ¼ and ¾ of the width of the conductive paste layer, i.e. such as a silver paste layer. The present invention novel structure prevents the overflow of the carbon nanotubes, after a curing process for the nanotubes is conducted, onto the sidewall of the conductive paste layer, and thus significantly improves the electron density projected toward the flourescent powder coating layer to produce an image with reduced electron scattering. As a result, image clarity, definition and contrast can be improved in the FED device.

Abstract: A field emission display panel that utilizes nanotube emitters as electron sources and is equipped with two cathodes i.e. a primary cathode and an auxiliary cathode, and an anode is provided. The nanotube emitters can be suitably formed by nanometer-dimensioned hollow tubes of carbon, diamond or diamond-like carbon mixed in a polymeric-based binder. The nanotube emitters are formed in two parallelly-positioned, spaced-apart rows on top of an electrode layer such as a silver paste by a thick film printing technique. Since both the primary cathode and the anode are formed on the bottom glass plate, the operating voltage can be controlled by the thickness of the dielectric layer that is used in forming the nanotube emitter stacks. An auxiliary cathode formed of an electrically conductive material is coated on the interior surface of a top glass plate to further repel electrons in a downward direction toward the anode on the bottom glass plate.

Abstract: The present invention disclose a method for measuring a thermal expansion coefficient of a thin film, in which the thin film is first deposited on two substrates having different thermal expansion coefficients under the same conditions. For each of the two deposited substrates, a relationship between the thin film stresses and the measuring temperatures is established by using a phase shifting interferometry technique, in which the stresses in the thin films are derived by comparing the deflections of the substrates prior to and after the deposition. Based on the two relationships the thermal expansion coefficient, and elastic modulus, E f ( 1 - v f ) , can be calculated, wherein Ef and &ngr;f are the Young's modulus and Poisson's ratio of the thin film, respectively.

Abstract: A diode structure field emission display panel that utilizes a nanotube emitter layer as the electron source and having a cathode and an anode formed on the same panel substrate is provided. The electron source of the nanotube emitter layer can be suitably formed by nanometer dimensioned hollow tubes of carbon, diamond or diamond-like carbon mixed with a polymeric-based binder. The nanotube emitter material can be advantageously applied on top of an electrode layer such as a silver paste by a low cost thick film printing technique. Since both the cathode and the anode are formed on the same bottom glass plate, the operating voltage is controlled by the thickness of a dielectric material layer that is used to form the nanotube emitter stacks. As a result, the distance between the top glass plate and the bottom glass plate can be suitably selected to allow a rapid evacuation of the panel cavity to form a high vacuum therein without affecting the operating voltage of the device.
