Glossary
Erase voltage :
Erase pulse voltage required for erasing cells from AC plasma panel.[symbol : Ve]
Evacuating (Interchangeable terms : evacuation, exhaust) :
Process where unwanted gas is rid from device.
Exhaust tubulation (Interchangeable terms: exhaust tube, exhaust pipe) :
Tube shaped hole in device connected to external vacuum pump, for controlling the initiation from device
during process. This is usually glass tube that prevents with flannelet after filling proper gas
Filling gas (Refer to gas mixture) :
After removing air, plasma panel goes through filling with proper electric and optical gas. Therefore, panel
gas composition is commonly called "filling gas".
Firing voltage :
Minimum voltage where triggers discharge in plasma device[symbol : Vf]
Flicker :
Fast and instant changes in luminance, perceivable in almost regular luminance experiment pattern.
Front substrate :
Substrates closer to the viewers, made of transparent material such as glass
Full color display :
Full color image (for example, image with more than 8 bit color tone) realizable display
Fpc(Flexible Printed Curcuit) :
Flexible substrates with circuited copper foil on polyimide
Gas mixing ratio (Interchangeable terms: gas mixture, gas composition) :
Gas composition within plasma device. It is usually expressed with ratio of the constituent gas.
Gas voltage (Interchangeable terms: gas break down voltage) :
Voltage where electrode and ion within plasma device can generate additional electrodes and ions.
-Thus, increasing the electric current within the device sharply. (break down or overflowing)
Glass substrate :
Substrates consisted of glass
Glow discharge :
Plasma discharge taking place under pressure of tens of millimeter. This is defined by ionization generated
by activated electrons in discharge space and electron release in cathode by ion bombardment.
Gradation :
Gradual change in characteristics such as luminance and chromaticity
Gray scale :
The range of luminance acquired when displayed from black to white.
High strain point glass :
Glass of which strain point (temperature with viscosity of 1014.5 poise) is relatively high
Image retention :
Continuous existence of image after the stimulation is removed.
