For lighting, I think you need to use a chip MC34844. Do the signals from the pinch Bl_power (2..5),&nbsp; Brightness (8), Bklt_en (9) control the backlight? In the datasheet, I did not find any electrical characteristics anywhere...<BR />The backlight requires a constant current. Adjusting the brightness of PWM mc34844 will provide a constant current output?</P></BODY></HTML> Thu, 11 Apr 2019 11:41:06 GMT konstantin_alfi 2019-04-11T11:41:06Z Motherboad to display schematic https://community.nxp.com/t5/Other-NXP-Products/Motherboad-to-display-schematic/m-p/891787#M7197 <HTML><HEAD></HEAD><BODY><P>Please tell me how to connect this display to the motherboard?
