VATN LCD is a type of LCD display mode with high contrast, VATN (Vertically Aligned Twisted Nematic ) lcd, it is wider viewing angle than
the regular TN LCD display mode, it is widely used in the industrial display
domain because of its outstanding display effect, such as White goods electronics ,Security control system, Automotive,
Audio, Medical devices, POS machine, Dash board applications. VATN displays work in a negative display
mode with a transmissive polarizer and easier to read in dark environments. Maclight display is the specialist on VATN LCD display and

About VATN LCD display: When the VATN lcd in non-display status, there
is no electric current is running through the lcd cells, the liquid crystal materials
naturally align vertically direction between two ITO glass substrate panes, combine
with the directions of top polarizer and bottom polarizer, the VANT LCD blocks
the transmission of light from the backlight. This make the crystals to opaque
and lead to a black display effect. When an electric current is applied, the liquid crystal materials shift to a
horizontal position arrayment between the ITO glass substrates, combine the
polarizer’s directions, this would allow light to pass through VA TN LCD resulting
in a white display screen.
Becausetheliquid crystal
alignment direction inside the ITO substrate for VATN LCD display, it is not
easy to leak the light through the VA TN liquid crystal alignment, because its
liquid crystal alignment only in 0° or 180° instead of the twist 110°in the regular TN lcd display, that is
the reason VATN lcd could provide the high contrast and wider viewing angle than
regular TN LCD.
VATN display effect:
VATN lcd Display is an good alternative for traditional TN lcd
or alphanumeric LCD display.
