Appendix E: Connecting LCD to NOVA-8890
NOVA-8890 can support both one-channel and two-channel LVDS LCD through
connector J3. We use the LCD–LTM15C423S (two-channel) for an example to
explain the signal mapping and data format.
The pixel data of LTM15C423S is 48-bit wide. To use 36-bit LCD, please neglect
the third pair of signals–(DATA3+, DATA3-). In other words, only the data of
MSB (R2 ~ R7, G2 ~ G7, B2 ~ B7) are left. On the other hand, if the one-
channel LCD is used, only the first channel (CH1) is necessary. The way to deal
with 18-bit data is the same as that of 36-. For different types of LCD, you
should refer to the data sheet for more detailed information to make the right
connection.
