Abstract
A mini LED television control system and method to reduce loss includes a power supply used for supplying power to a backlight board after a voltage is adjusted; a control board connected to the power supply, the control board including an FPGA used for detecting a current value and controlling a power supply output voltage, an analog-to-digital conversion chip used for collecting the voltages of sampling circuits, and a plurality of sampling circuits connected to a plurality of light boards and used for collecting voltages of the light boards; constant current ICs disposed on the light boards and used for providing light bar voltages and sending brightness information; and a mainboard connected to the control board and used for enabling and synchronizing backlight brightness signals. The control board converts brightness information sent by the mainboard and then sends the information to the constant current ICs on corresponding light boards.
