Half Tone Display (FRC: Frame Rate Control Function)
The HD66520 incorporates an FRC function to display four-level grayscale half tone.
The FRC function utilizes liquid crystal characteristics whose brightness is changed by an effective value
of applied voltage. Different voltages are applied to each frame and half brightness is expressed in
addition to display on/off.
Since the HD66520 has two-bit grayscale data per one pixel, it can display four-level grayscale and
improve user interface (Figure 6). Figure 7 shows the relationships between voltage patterns applied to
each frame, the effective voltage value, and brightness obtained.
