ScreenTek is proud to provide you this glossary of common terms in the laptop LCD screen industry, and in the laptop notebook industry. Feel free to become more familiar with the terms we use throughout our site. If you notice any glaring omissions, we'd be glad to hear about those. Drop us a line at sales@screentekinc.com.
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 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.
(more Electronic terms)
Wattage
A measurement of power, typically electrical power, expressed in watts or kilowatts.
