Motherboad to display schematic

Please tell me how to connect this display to the motherboard? For lighting, I think you need to use a chip MC34844. Do the signals from the pinch Bl_power (2..5),  Brightness (8), Bklt_en (9) control the backlight? In the datasheet, I did not find any electrical characteristics anywhere...
The backlight requires a constant current. Adjusting the brightness of PWM mc34844 will provide a constant current output?
