The i.MX processor’s LCDC can directly interface with Sharp HR-TFT panels that require Sharp dedicated
signals. Figure 7 shows how to connect the LCDC interface signals to a 18 bpp TFT panel. The two LSBs of the
blue (B0) and red (R0) component are tied to B1 and R1, respectively. The diagram shows a panel that does not
require Sharp dedicated signals, therefore, they are shown not connected (nc).
5.1
If the panel illustrated in Figure 7 required Sharp dedicated signals—that is, it was a Sharp panel and the timing
ASIC for the dedicated signals was not provided—the i.MX processor could be used to directly drive the panel by
making direct connections to those signals. The four signals dedicated to Sharp panels are identified in Table 5 on
page 10.
