6-1-1 Angle of View
Angle of view means the normal visible range (angle) of a screen.
In an LCD display, the angle of view is narrow compared with a CRT or PDP (Plasma Display Panel). The
viewing angle of the typical TN type LCD display is about 100º. However with the new improved technolo-
gy that has been developed the angle of view for LCD display has increased to 160º or 170º. This
improved system will be described later. (The angle of view for a CRT or PDP is 180º.)

6-1-2 Response Characteristic
The response characteristic of the LCD display is the speed at which the display is refreshed by the input
signal (video data signal).
If this response characteristic is slow, an afterimage will appear on the screen. Therefore, in large screen
LCD television, improving this response characteristic becomes very important.
