TFT Technology from Varitronix Boasts Widest Viewing Angle
Varitronix is launching the first in a new family of colour TFT displays, using HFFS technology to deliver exceptional image quality even when viewed at extreme angles. The first Varitronix HFFS TFT display to be released is a 3in WQVGA model (480 x 272 pixels) in 16:9 widescreen format.
HighHFFS works by optimising a screen printing treatment in the LCD cell which alters the alignment of the liquid crystals. The result is vastly improved viewing properties such as a contrast of 500:1, as well as higher light transmission with a 30-40% higher aperture ratio than conventional vertically aligned TFT displays. As a result, the backlight can be turned down for certain applications, saving power. HFFS also requires a much lower driving voltage than standard vertically aligned TFTs in this size.
A further significant feature of HFFS is its exceptional sunlight readability. The innovative design of the LCD increases inner reflectance while the modified polarizer reduces outer reflectance.
