Introduction

Product Description
When updating images with high contrast and high density (such as sonar or dense
information data) the LCD’s brightness varies with the rate of updating. This
luminance variation, referred to as ‘LCD Flicker’, can cause eye-fatigue and affect the
interpretation of the displayed data. With the ISIS LFC kit here described, a unique set
of algorithms is integrated in the ISIS display that reside in the hardware interface of
the display (between the graphics generator and the LCD). This feature compensates
for LCD Flicker without affecting the displayed data.
