Comparison of VATN displays to displays with the OLED technology is intentional… Naturally, VATN (vertically aligned twisted nematic) displays are not the same as OLED ones but by their (perceptual) features they significantly overcome classic STN and FSTN displays thus creating a very interesting alternative if you´re searching for something better and at the same time you´re not willing to invest to OLED displays.
What´s the key advantage of VATN displays?
It can be said, that mainly a great contrast of 1:100 up to 1:1000 (FSTN has typically 1:10 to 1:15) and excellent viewing angles which really significantly overcome STN/FSTN displays.
VATN displays are typically available as character displays or also custom made with various icons.
Last big benefit advantage of VATN displays is only about 15-25% higher price in comparison to standard types, what´s significantly less than in case of OLED displays. Perhaps the only small limitation is the fact that majority of available types is with a viewing direction of “12:00“ i.e. slightly from the top, but in respect to wide viewing angles this doesn´t matter in praxis.
available backlight: white, green, yellow-green, red, blue
