4.3.1 Connecting an LCD
The expansion board has two physical interfaces for Emerging Display Technologies (EDT)
LCDs:
●
J600
– for ET057010DHU
– 24 bpp
– direct 8:8:8 RGB signaling
Table 3 lists J600 configuration options.
See also ET057010DHU LCD interface connector (J600) on page 19
●
J601
– for devices that have EDT displays with a unified interface
– 16 bpp
One bpp is normally not used, but this pixel is still output. It can be used as a
bright bit to connect to the
least significant bit (LSB) of R, G, and B components of
a 6:6:6 TFT panel.
– direct 5:5:5 RGB
This interface can cover LCD screens from 3.5 to 7 inches (such as ET057090DHU
and ET070080DH6).
Table 4 on page 11 lists J601 configuration options.
