A reference circuit for the LCM interface is shown below.
Figure 17: Reference Circuit Design for LCM Interface
MIPI is high-speed signal lines. It is recommended that common-mode filters should be added in series
near the LCM connector, so as 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 LCM models share the same IC, it is recommended that the LCM module factory
burn the OTP register to distinguish different screens. Customers can also select the LCD_ID pin of LCM
to connect the ADC pin of the SC200L module.
The external backlight driving circuit needs to be designed for LCM, and a reference circuit design is
shown in the following figure. The backlight brightness adjustment can be realized by the PWM pin of the
SC200L module by adjusting the duty ratio.
