It is recommended to read the LCM ID register through MIPI when compatible design with other displays
is required. If several LCMs share the same IC, it is recommended that the LCM factory should burn an
OTP register to distinguish different screens. You can also connect the LCD_ID pin of LCM to the ADC
pin of the module, but you need to make sure that the output voltage of LCD_ID should not exceed the
voltage range of the ADC pin.
You can design the external backlight driving circuit for LCM according to actual requirements. A
reference circuit design is shown in the following figure, in which the PWM pin is used to adjust the
backlight brightness.
