gm5110/20 Preliminary Data Sheet
June 2002

C5110-DAT-01C
4.8.3 Moiré Cancellation
The gamma curve and other non-linearities can affect the energy distribution of pixels when
scaled to different areas of the screen. This is an example of the Moiré effect. The
gm5110/20 has hardware features to negate the Moiré effect, improving the scaling quality.

The gm5110/20 has the capability to completely bypass internal processing. In this case,
captured input signals and data are passed, with a small register latency, straight through to
the display output.
The gm5110/20 is also able to bypass the zoom filter.

The gm5110/20 provides an 8 to 10-bit look-up table (LUT) for each input color channel
intended for Gamma correction and to compensate for a non-linear response of the LCD
panel. A 10-bit output results in an improved color depth control. The 10-bit output is then
dithered down to 8 bits (or 6 bits) per channel at the display (see section 4.11.3 below). The
LUT is user programmable to provide an arbitrary transfer function. Gamma correction
occurs after the zoom / shrink scaling block.
The LUT has bypass enable. If bypassed, the LUT does not require programming.

The Display Output Port provides data and control signals that permit the gm5110/20 to
connect to a variety of flat panel or CRT devices. The output interface is configurable for 18
or 24-bit RGB pixels, either single or double pixel wide. All display data and timing signals
are synchronous with the DCLK output clock.
4.11.1 Display Synchronization
Refer to section 4.1 for information regarding internal clock synthesis.
The gm5110/20 supports the following display synchronization modes:
Frame Sync Mode:
The display frame rate is synchronized to the input frame or
field rate. This mode is used for standard operation.
Free Run Mode:
No synchronization. This mode is used when there is no valid input
timing (i.e. to display OSD messages or a splash screen) or for testing purposes. In
