As shown in the figure, The BackLight Switch is used to control the backlight of the screen. When the backlight is turned ON, the backlight is always on, when the backlight is turned OFF, the backlight is always off.
If BL_JMP is shorted, the user can control the effect of the backlight by the program, flashing every 1 second, flashing every 0.5 seconds, and so on.
! ! ! Note: Once the BL_JMP is shorted, the BackLight Switch must be turned OFF. Otherwise, the module may be short-circuited. The display and the Raspberry Pi were burned out due to excessive current.
