TWI290246B - Field emission display panel equipped with two cathodes and one anode - Google Patents

Abstract

This invention disclosed a field emission display (FED) panel, in which nano-scale tube emitters are used as electron sources. The electron sources are equipped with two cathodes, which are one main cathode and one auxiliary cathode, and one anode. These nano-scale tube emitters are made of nano-scale carbon, diamonds, or diamond-like hollow carbon tubes that are properly mixed with a base-adhesive polymer. These nano-scale tube emitters are formed on two paralleled and spaced rows that are disposed on one electrode layer made by a thick film printing technique. For example, the electrode layer can be formed on the top of a silver electrode layer. Because the main cathode and the anode are simultaneously formed on the glass substrate at the bottom, the operating voltage can be controlled by the thickness of the dielectric layer that is used to pile the nano-scale tube emitters. The auxiliary cathode is made of an electricity-conducting material that is coated on the inner surface of the glass substrate at the top in order to further downwardly expel electrons to the anode on the glass substrate at the bottom. As a result, the distance between the top and the bottom can be adjusted, so the panel can introduce high vacuum in a short time without changing the operating voltage of the device. The FED panel of this invention can be made into a large-size display panel with low cost.

Description

1290246 Ministry of Economic Affairs Intellectual Property Office Staff Consumer Cooperative Printed A7 B7 V. INSTRUCTIONS () Field of the Invention: The present invention relates to a field emission display (FED) device and a method of fabricating the same, and in particular to a device A cathode emission display device as a source of electron emission from a cathode, an anode, and a nanotube emitter, and a method of fabricating the device using a thick film printing technique. BACKGROUND OF THE INVENTION In recent years, flat panel display screen devices have been developed and widely used in electronic applications, such as applications on personal computers. A very common flat panel display screen device is an active matrix liquid crystal display (LCD) that enhances resolution. However, liquid crystal display devices have many inherent limitations that make them unsuitable for many applications. For example, liquid crystal displays have a number of fabrication constraints, including a slow deposition process that coats glass panels with amorphous germanium, high manufacturing complexity, and low yield manufacturing processes. Moreover, the liquid crystal display device requires a fluorescent backlight, which not only consumes a large amount of power but also generates a large amount of light. It is difficult to display the image of the screen in the state of strong light or wide viewing angles, which further limits the liquid crystal display screen in many application fields. The use of other flat panel display screen devices has been developed in recent years, 3 ---r---;--- — !^j^ loading -------- order ------ --- (Please read the notes on the back and fill out this page)

One of these lack of cheek devices is a field emission display device that overcomes some of the limitations of LCDs and sways.

City J and k offer several important advantages over LCD devices. For example, comparing a ceremony from μ-f to a traditional 溥 film transistor (TFT) liquid crystal display panel, the field emission display has a high contrast ratio (contrast rati0), a larger viewing angle, High maximum brightness, low power consumption and a wider temperature operating range. Between the FED Xiao LCD - the most extreme difference is that, unlike LCD, just apply colored phosphor powder to generate your own source of light. There is no need for complicated, power-hungry backlights, filters, and therefore, almost all of the light produced by the FED can be seen by the user. Further, the FED does not require a large number of thin film transistors, thus eliminating some of the main sources of high cost and yield issues for active array LCDs. In an FED, electrons are emitted from a cathode and collide with the phosphor powder coated on the back of the transparent cover to produce an image. This type of cathodoluminescence process has been known as one of the most efficient methods of producing light. In contrast to conventional cathode ray tube (CRT) devices, each pixel or emission unit in the FED has its own source of electrons, in other words a typical array of emitting microtips. A voltage difference exists between a cathode and a gate electrode that takes electrons from the cathode and accelerates electrons toward the phosphor powder. The emission current' and the brightness of the display screen are strongly dependent on the work function of the emission material.

Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperative printing 5, invention () (work function). In order to achieve the necessary efficacy of the FED, the cleanliness and uniformity of the source material of the emitter is very important. In order for electrons to travel in the fed, most of the FED is evacuated to a low voltage, such as 107 Torr, which not only provides a log mean free path for the emitted electrons, but also avoids contamination of the microtips. With degradation. Using a foeus grid to collimate (c〇Uimate) the electrons pulled from the microtips can increase the resolution of the display. The initial development of field emission cathodes was the use of molybdenum metal microtip emitters. In such devices, the germanium wafer is first oxidized to produce a thick tantalum oxide layer, followed by a metallic gate layer deposited over the oxide. This metallic barrier layer is then patterned to form a gate opening, and then the ruthenium oxide below the opening is etched, the lower portion of the gate is cut and a well is created. A sacrificial material layer such as nickel is deposited to avoid nickel deposition into the emitter well. The molybdenum is then deposited in a normal incidence such that a pointed cone grows in the groove until the upper opening is closed. When the sacrificial layer of nickel is removed, an emitter cone will remain. In another design, the 矽 microtip emitter first directs a thermal oxidation on the crucible, then shapes the oxide and selectively etches to form the stalk tip. Further oxidation or etching protects the crucible and sharpens the paper size for the Chinese National Standard (CNS) A4 specification (210 x 297 mm) --r--------1 ^--- -----^----I .

In the fabrication of such FED devices, a deposition-amorphous germanium film is required] The range of λ conductivity is between the micro-amorphous stone and the η + doped amorphous stone. The conductivity of the η + -doped amorphous stone can be controlled by adjusting the number of phosphorus atoms in the film. - In the production of FED t, the device is contained in a very low pressure groove so that electron emission is not hindered. For example, a low voltage of 107 Torr is generally required.

The Spindt-type electron emission source, the novel thick film printed fed panel of the present invention, requires substantially lower driving voltages during operation. Moreover, the fed panel of the present invention is more advantageous in comparison with a conventional VFD (Vacuum Fluorescent Display), which has a plurality of sources of hot electrons, and thus is difficult to apply to a place where a dynamic video drive is required.
