SVGA (Super Video Graphics Array)
Also referred to an exten-
sion of the VGA video standard. SVGA video adapters support
resolutions of 800 x 600 pixels and higher with up to 16.7 million
colors (known as true color).
TFT (Thin Film Transistor)
A technology used to make active
matrix LCD panels where each pixel has its own transistor
switch. This technology allows for sharper looking colors than
ColorStripe or TSTN.
TFT is used in Amorphous TFT and Polysilicon TFT.
Vertical Rate (Frequency)
The number of times the screen is
refreshed per second. Typically shown as a measure of hertz
(Hz).
VGA (Video Graphics Array)
Also referred to as Video Graph-
ics Adapter. Introduced by IBM in 1987. VGA is an analog signal
with TTL level separate horizontal and vertical sync. The video
outputs to a 15 inch HD connector, has a horizontal scan frequen-
cy of 31.5 kHz, and vertical frequency of 60 to 70 Hz non-inter-
laced. The signal has a Pixel by Line resolution of 640 x 480 with
a color palette of 16 from 256,000.
