V, W, X, Y, Z Terms ยป 19 definitions


Vcon Modulation

The PLL500-17 is a low cost, high performance and low phase noise VCXO for the 17 to 36MHz range, providing less than -130dBc at 10kHz offset at 35.328MHz. The very low jitter (2.5 ps RMS period jitter) makes this chip ideal for applications requiring voltage controlled frequency sources. Input crystal can range from 17 to 36MHz (fundamental resonant mode).


Vertical back porch

The amount of time between the end of a vertical sync and the start of the next vertical active time.


Vertical front porch

The amount of time between the end of the vertical active time and the start of the vertical sync pulse.


Vertical Interconnect Access

which is a vertical electrical connection between different layers of conductors in printed circuit board design.


Vertical Stripe Color Filter Arrangement

is a way to increase the apparent resolution of a computer's liquid crystal display (LCD) or Organic Light Emitting Diode (OLED) display by rendering pixels to take into account the screen type's physical properties. It takes advantage of the fact that each pixel on a color LCD is actually composed of individual red, green, and blue subpixel stripes to anti-alias text with greater detail or to increase the resolution of all image types on layouts which are specifically designed to be compatible with subpixel rendering.


Vertical sync

During the vertical blank time, the monitor receives the vertical sync pulse which is used for synchronizing the monitor to operate exactly synchronous to the PC graphics card. After receiving the vertical sync pulse, the monitor returns the beam to the upper left corner of the screen.


VGA

Refers to "video graphics array", a type of screen resolution. This resolution measures 640 x 480, creating a 1.33x aspect ratio (Standard). Related to the VGA connector used on many external displays of various resolutions.


Viewing angle

All of the angles in which a display may be viewed.


Viewing Angle

The range of angles over which the contrast ratio of a display exceeds 10:1.


Voltage

Electric potential or potential difference expressed in volts.


Wattage

A measurement of power, typically electrical power, expressed in watts or kilowatts.


Wavelength

The distance between one peak of a wave and another, both in the same wave pattern.


WSVGA

Refers to "wide super video graphics array," a type of screen resolution. This resolution measures 1024 x 600, creating a 1.71x aspect ratio (Wide).


WSXGA

Refers to "wide super extended graphics array," a type of screen resolution. This resolution measures 1280 x 854, creating a 1.50x aspect ratio (Wide).


WSXGA+

Refers to "wide super extended graphics array, plus," a type of screen resolution. This resolution measures 1680 x 1050, creating a 1.60x aspect ratio (Wide).


WUXGA

Refers to "wide ultra extended graphics array," a type of screen resolution. This resolution measures 1920 x 1200, creating a 1.60x apect ratio (Wide).


WXGA

Refers to "wide extended graphics array," a type of screen resolution. This resolution can measure 1152 x 768 (1.50x aspect ratio, Wide), 1280 x 768 (1.66x aspect ratio, Wide), 1280 x 800 (1.60x aspect ratio, Wide), or 1366 x 768 (1.78x aspect ratio, Wide).


WXGA+

Refers to "wide extended graphics array, plus," a type of screen resolution. This resolution measures 1440 x 900, creating a 1.60x aspect ratio (Wide).


XGA

Refers to "extended graphics array," a type of screen resolution. This resolution measures 1024 x 768, creating a 1.33x aspect ratio (Standard).
