FIELD: electricity.
SUBSTANCE: inductive step-up circuit is proposed, used in different display modes to increase the input voltage to the operating voltage required for the operation of the LEDs in the current display mode, and the mentioned display modes include a two-dimensional display mode and a three-dimensional display mode, a detection circuit including the first resistor, one terminal of which is connected to earthing and the other terminal of which is connected to the source of the switching transistor of the inductive step-up circuit and the controller used for supplying PWM signal exciting the inductive step-up circuit, and for detecting whether the detected voltage corresponding to the detected current exceeds the value of the reference voltage.
EFFECT: implementation of the same circuit protection against overcurrent in different display modes to prevent the element from failing or to disrupt the protection circuit.
