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.
