1.4.9 Panel
Interface
An alternative display to the standard CRT monitor is digital flat panel interfaces in which the color
of each pixel is digitally encoded. The panel data may be transferred in parallel where the color of
each pixel is transferred over a number of signal lines at rates up to 80MHz.
Lynx3DM supports both color dual scan STN (passive) and color TFT (active) panel interface. It
can also support color TFT panel with RGB analog interface. For color DSTN panel, Lynx3DM can
support 16-bit and 24-bit interfaces up to 1600x1200 resolution. For color TFT panel, Lynx3DM
can support single pixel per clock of 9-bit, 12-bit, 18-bit, 24-bit, or double-pixel per clock of 24-bit,
36-bit interfaces up to 1280x1024 resolution.
Lynx3DM supports two separate digital LCDs. Both LCDs need to be TFT interface. FP1 has to be
only 18-bit TFT interface and FP2 has to be 24-bit TFT interface. DSTN panel can not be supported
under dual digital LCD mode. Dual Digital LCD mode is supported through the Virtual Refresh
architecture. FP1 and FP2 must be in Virtual Refresh mode. FP1 clocks the data based on VRCLK
(Virtual Refresh Clock); whereas FP2 clocks the data based on FIFOCLK (based on Video Clock).
The parallel interface is only suitable for short distance (less than 50 cm) and is typically
implemented by using of ribbon cables. One should be careful in the EMC design of the box and
cabling when this interface is used.
It should also be noted that the signal level of this interface is 3.3V, but does comply with the TTL
signal levels. Some - most older displays require 5V signal level.
