Development of field emission displays

Abstract

High-voltage triode flat-panel display using field-emission nanotube-based thin films Field emission displays ͑FED͒ are drawing attention as one of the most promising flat panel displays. Currently, the development stage of Spindt-type FEDs with Mo emitter is close to an end. The monocolor Spindt-type FEDs are being supplied to the market, and the color FEDs are ready for mass production. FED is also expected as a low power consumed display device, because the power, in principle, is consuming at the light emitting part only. The present status of FEDs with Spindt type and nanocarbon emitters are reported in this article.

Low-energy Cathodoluminescence for (Oxy)Nitride Phosphors

“…To answer these society needs, energy production must be "greener" that means, reducing the energy consumption from traditional sources or developing new environmental-friendly materials. Light emitting diodes (LEDs) and field emission displays (FEDs) have got significant attention due to their compactness, improved performance and lower power consumption compared to the actual displays, such as mercury gas-discharge fluorescent lighting or plasma displays [1][2][3][4][5] . The key factor for light source of LED and FED is a high-efficient phosphor.…”

Field Emission Properties of Single-Walled Carbon Nanotubes with a Variety of Emitter Morphologies

“…uniformity of emission sites and high extractive ratio (anode current/cathode current) in a triode-configuration, have not achieved levels comparable to the Spindt-type FED. 4) Due to their large tip-curvature and metallic conductivity, excellent field emission properties of CNTs have been demonstrated by numerous groups, however their practical use has not yet been realized.…”

An Efficient Macromodeling Approach for Simulating Carbon-Nanotube Field-Emission Triode Devices in Display Applications

“…The 1-D piecewise linear (PWL) function in SPICE is used to describe the current sources through modeling the I ac -V G−C and I gc -V G−C characteristics by directly specifying the experimentally measured data points [5]. The syntax of using the PWL function is (1) Gxxx n + n − in + in − x1, y1 x2, y2, . .…”

“…F IELD-EMISSION DISPLAYS (FEDs) are characterized by superior display performances such as fast response time, wide viewing angles, wide operation temperatures, cathode-ray-tube-like colors, ultraslim features, low cost, and low-power consumption [1]. Carbon nanotubes (CNTs) have inherent advantages as a field emitter material due to their excellent field-emission (FE) characteristics, strong chemical stability, and high mechanical strength.…”

“…The triode structure with a gate electrode much closer to the cathode to extract electrons has high-emission current densities at low voltages and is therefore preferred for FEDs, which leads to lower driving voltage, high light efficiency, smooth gray scale imaging, and fast response for moving pictures [3]. In the past, much effort was expended on optimizing the process technologies and device structures to achieve higher emission current density, lower turn-on voltage, lower gate leakage for low power, and higher efficiency [1], [3]. To integrate a given FE triode device into a display system for desired performance, it is highly preferred to be able to timely and accurately evaluate the device's electrical behaviors in the early circuit and system design stage.…”
