When talking about LCD displays everyday, there will be a lot of parameter problems, one of which seems to be not the focus but is very important, is the "LCD display angle". The viewing angle range of the LCD display refers to the angle at which the customer observes the content displayed on the screen from different directions. When viewing beyond a certain range, color distortion or ghosting will occur.
The viewing angle of a monochrome LCD display is usually 3 o'clock, 6 o'clock, 9 o'clock, and 12 o'clock. At present, most monochromatic LCD screens use 6 o'clock and 12 o'clock. In terms of angles, there is an optimal visual angle at 6 o'clock or 12 o'clock. For example, for a common TN screen, although the viewing angle is not particularly good, it wins at a cheap price, which is more suitable for many occasions.
The viewing angle range of the LCD display of the following materials:
TN: 30 degrees; HTN: 45 degrees; STN: 60 degrees to 90 degrees; FSTN: 90 degrees to 120 degrees.
