[Question] Power saving mode and wakeup command for Dwin display

Hotter

Hi, I have screen DMG85480C050_03WN. Is there "Power off/Power save" command and "Wakeup" commands available to send with UART to display (To reduce power consuption when display is not needed)?

Hi Sir.
You can write the cfg configuration as below:
0x0C,0x0D,0x0E belong to the backlight setting address.
0x0C is the normal light level, the scope is 0x00-0x64
0x0D is the standby brightness. the scope is 0x00-0x64
0x0E is the required time to wake up the display. the scope is 0x0001-0xFFFF, the unit is 10mS.
For example, you wanna to wake up the display in 10 minutes, then
0x0E is 0x03E8(10*1000/10, turn to 16 hex.
0x0D can be set 0x32, half of the brightness, depends on you.
0x0C can be set 0x64, full brightness, depends on you.

You can also set the brightness via UART. The code example is as below:
5A A5 07 82 0082 64 32 03E8
82 means register
0082 is the system variable interface address
64 is the start brightness, 0x00-0x64
32 is the closure brightness,0x00-0x64
03E8 is the time.
