Default What is LCD TV?

Quote:
A liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It is often utilized in battery-powered electronic devices because it uses very small amounts of electric power.
Important factors to consider when evaluating an LCD monitor:

Quote:
* Resolution: The horizontal and vertical size expressed in pixels (e.g., 1024x768). Unlike CRT monitors, LCD monitors have a native-supported resolution for best display effect.
* Dot pitch: The distance between the centers of two adjacent pixels. The smaller the dot pitch size, the less granularity is present, resulting in a sharper image. Dot pitch may be the same both vertically and horizontally, or different (less common).
* Viewable size: The size of an LCD panel measured on the diagonal (more specifically known as active display area).
* Response time: The minimum time necessary to change a pixel's color or brightness. Response time is also divided into rise and fall time.
* Matrix type: Active or Passive.
* Viewing angle: (coll., more specifically known as viewing direction).
* Color support: How many types of colors are supported (coll., more specifically known as color gamut).
* Brightness: The amount of light emitted from the display (coll., more specifically known as luminance).
* Contrast ratio: The ratio of the intensity of the brightest bright to the darkest dark.
* Aspect ratio: The ratio of the width to the height (for example, 4:3, 16:9 or 16:10).
* Input ports (e.g., DVI, VGA, LVDS, or even S-Video and HDMI).
