Hello,
My goal is to connect the Leopardboard DM365 to an LCD panel and I am having trouble understanding the hardware requirements for the LED backlight system.
Some specs on the LCD panel:
Model: LP156WH4-TLN2
Color depth: 18 bit
Signal Interface: LVDS (1 ch, 6-bit)
Lamp Type: WLED
I have attached the full datasheet for reference.
To connect to the LVDS interface I am using the SN75LVDS83B with the following configuration:

The module connector on the back of the LCD panel includes backlight connection pins, namely PWM, LED_EN, and VLED.
Is it possible to connect the PWM and LED_EN directly from the DM365 and a 12V signal to VLED?
If so, which pins do PWM and LED_EN connect to?
If not, can you please point me in the right direction? Would I need to include additional LED drivers?
Attached is the schematic for the Leopardboard 365 for your reference.
I sincerely appreciate your help,
Chris
