19.4: A Novel AC PDP with Shadow Mask

A newly developed AC PDP with shadow mask (SM-PDP) is presented in this paper. Using shadow mask made of invar will cut down the manufacture cost of PDP and improve the performance instead of normal rib walls made of dielectric materials significantly. A 14″ monochromatic SM-PDP (240×200) and a 14″ color SM-PDP (80×RGB×200) have been made and video display have been realized.

11.4: A Novel Shadow Mask PDP with High Luminance and Contrast

An improved AC PDP with shadow mask SMPDP is presented in this paper. The manufacture cost of SMPDP can be reduced significantly by replacing the normal dielectric rib with shadow mask. A 14″ full color SM-PDP 240×RGB×180 prototype TV set has been made. High luminance with 550cd/m2 and high contrast over 5000:1 have been achieved by applying high Xe content and True Black driving scheme.

A study of the optimum field emitter shape for vacuum electronics applications

A summary of a study on optimum field emitter models is introduced in this paper. Ten models of field emitter are presented and the electric field on the top of these field emitters in the given structure of triode are calculated using EMAS software. It is seen that sharp pyramid-on-post is the best shape of field emitter due to high field enhancement, reasonable mechanical stability and thermal contact, low capacitance and high transconductance.

P-54: Three-Dimensional Investigation of a Novel Plasma Display Panel with Metal Barrier Plate

The discharge characteristic of a novel color plasma display panel with metal barrier plate (SM-PDP) has been studied by 3D simulation. Compared with the conventional coplanar PDP (ACC PDP), the novel structure has advantages of lower cost, lower ignition voltage, higher response frequency and higher brightness substantially. The luminous effiacy of the SM-PDP experimental panel with novel structure is about 0.8–0.9lm/W without energy recovery circuit.

Two-dimensional simulation of the effects of the driving waveforms on the shadow mask PDP cell discharge

A new type of ac plasma display panel (PDP) with shadow mask (SM-PDP) is presented for its effective structures with lower cost. A two-dimensional self-consistent fluid model is used to analyse the discharge characteristics of the SM-PDP cell in a simplified driving scheme. The effects of the addressing time, the sustaining frequency, the duty ratio of the sustain voltage and the rise time of the voltage pulse on the discharge efficiency are investigated in this paper. The simulation results can help us optimize the driving scheme of SM-PDP.

25.3: Concept of a Carbon‐Nanotube FED with a Normally on Driving Under‐Gate Structure

The structure and working principle of a normally on driving under-gate FED are presented in this paper. Different from traditional under-gate driving scheme, field emission electrons are pulled out from cathode by anode voltage, and restrained by negative gate voltage. The electric field inside the emission region was calculated by finite element method. The emission property of the cathode was also studied by numerical calculation method. The results indicated that a uniform and large emission area could be obtained in this new under-gate FED. The study may provide a powerful theoretic support for the feasibility of this new kind under-gate FED. This normally on driving under-gate FED achieves large emission area, notable emission uniformity, high luminance efficacy and high anode voltage.

Novel Method for Simulating Optical Properties of Reflective Cholesteric Liquid Crystal Displays

In this study, a new method is used, which is much simpler than the layered numerical calculation method, to simulate the reflectivity of a multidomain reflective cholesteric liquid-crystal display (LCD). The theoretical calculation results are in good agreement with the experimental results. These simulations also show that the distribution of the helical axis of the liquid crystal has a pronounced effect on the viewing angle and colorimetric properties.

P‐109: Three‐Dimensional Simulation and ICCD Experiment in 25 inch SVGA Shadow Mask PDP

A new type of AC PDP with shadow mask (SM-PDP) has been presented for its effective structures with lower cost. A three dimensional self-consistent fluid model is used to analyze the discharge characteristics of the SM-PDP cell. The discharge process also can be observed by ICCD(Intensified Charge Coupled Device). The simulation results and the experimental results with ICCD accord nicely with each other. The simulation software is also used to investigate the driving scheme of SM-PDP.

Study of the atomic and molecular radiation in shadow mask PDP

The discharge process in a discharge cell of shadow mask plasma display panel (SM-PDP) has been calculated by means of fluid model. The relation between content of xenon in Ne-Xe mixture gas, pressure and efficiency has been investigated for SM-PDP. Simulation results show that the resonance xenon responsible for 147nm UV decreases with the increasing of the content of xenon and pressure, while the molecular xenon, radiating 173nm UV, increases. The efficacy of SM-PDP could be enhanced further if the phosphor is selected carefully considering of this conclusion.

P-66: Simulation Study of High Resolution SM-PDP

The discharge characteristics of novel high resolution Shadow Mask type AC PDP SM-PDP have been studied by Fluid-Monte Carlo Method. Compared with AC Coplanar PDP ACC PDP, the influence of discharge cell size on discharge process of SM-PDP is smaller than ACC PDP in a certain range. Therefore SM-PDP is easy to realize high resolution.
