LCD with Capacitive Touch
The RZ/G1H Qseven carrier board supports 7inch, 18bpp RGB
LCD “
ETM070001ADH6
” from
Emerging Display
Technologies Corporation (EDT) with capacitive touch panel. RZ/G1H
CPU’s
LVDS0 port is connected to primary LVDS
channel of Qseven MXM connector. This primary LVDS interface signals are directly connected to LVDS transmitter
(DS90CF384A) in carrier board which converts LVDS Interface signals to RGB and connects to RGB LCD connector (J8).
This RGB LCD connector (J8) is physically located at the top of board as shown below.
This RGB
LCD’s power enable and backlight enable is connected from
LVDS_PPEN (111
th
pin) & LVDS_BLEN (112
th
pin)
of Qseven MXM connector which is RZ/G1H CPU’s GPIO pins “
GP5_28
” and “
GP3_11
” respectively.
Also,
RGB LCD’s
brightness is controlled from LVDS_BLT_CTRL (123
rd
pin)
of Qseven MXM connector which is RZ/G1H CPU’s
TPU0TO2(GP0_22).
Note In RZ/G1H carrier board, LVDS brightness control GPIO from Qseven MXM connector (123
rd
Pin) is shared to both
primary & secondary LCD’s brightness control.
