Flat Panel LCD
The Common Terminologies In LCD TVs (2)
Like the first article about the common terminologies in Flat Panel LCD, here you can find another terminologies that related to Image Quality.
Luminous efficiency
The luminous efficiency is expressed by the amount of light per watt produced by the light source. The higher the luminous efficiency, the brighter the Flat Panel LCD displayed images
Number of pixels
The number of pixels indicates the resolution of the image. The number of pixels of digital image is expressed by the product of the number of pixels (dots) in the horizontal direction and the number of pixels (dots) in the vertical direction. The higher the number of pixels, the better the image quality. For Plasma TV, and Flat Panel LCD, the number of pixels is sometimes expressed by the following equation: number of pixels in horizontal direction x number of pixels in vertical direction x 3 (R/G/B, Red Green Blue)
Pixel
A pixel is a tiny dot that forms the smallest basic unit of a displayed image. Digital images are composed of pixels, with all of the text and images displayed on the screen consisting of Dots. Digital images are usually rendered by square pixels arranged vertically and horizontally in orderly manner.
Resolution
Resolution is a combination of values that express the quality of displayed images. A display’s resolution is indicated by the number of dots in the horizontal and vertical directions of the screen, such as 1024 x 768 dots. Higher values indicate clearer, sharper image reproduction. The larger of some Flat Panel LCD screen size, the higher the required resolution.
Gradation
Gradation renders to the smoothness of color expression.
