1, STN LCD screen
STN is the abbreviation of "Super Teisted Nematic", which is a passive passive matrix LCD,
which is the material of almost all black and white screen mobile phones. The color STN
LCD screen is based on a monochrome STN liquid crystal screen with a color filter, and
each pixel in the monochrome display matrix is divided into three sub-pixels, respectively,
through the color filter to display red, green, blue Colors to achieve a color picture. Due to
technical limitations, the current STN LCD screen has a maximum of 65,536 colors. Most of
the products seen on the market are 4096-color STN products, so STN is also known as "
pseudo-color".
