15 LCM
15.1 Schematic
eDP screen power consumption is big, a big current backlight IC should be used as shown
in Fig 15-1.
9.7'' big screen should chose 2-cell battery solution with R5002 SMT; 7.85'' smaller
screen can chose 1-cell battery solution with R5003 SMT.
Fig 15-1
Place pull-up and pull-down resistors R5000, R5001, and coupling capacitor C5000,
C5001 (which is on AUXN, AUXP auxiliary channel of eDP screen) close to screen base, as
shown in Fig 15-2.

If single MIPI screen is in use, please connect it to MIPI_TX channel as output channel.
MIPI_TX/RX cannot be taken as the default output channel.
