NOTE
The reference design of LCM1 interface is similar to LCM0 interface.
MIPI are high speed signal traces. It is recommended to add common-mode filters in series near the LCM
connector to improve protection against electromagnetic radiation interference.
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 LCM module 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 please note that the output voltage of LCD_ID should not exceed the voltage range
of the ADC pin.
Backlight driving circuits should be designed for LCMs. The module provides backlight driving output
which can be used to drive LCM backlight WLEDs directly. The features are listed below:
