LED Driver Circuit, Light Source Device, And LCD Device

摘要: An LED driver circuit which provides a cost reduction is provided by employing configuration allows size reduction. In at least one example embodiment, the includes first switching element, second sense resistor, sensing unit, calculator, and driver. The plurality of LEDs, resistor are coupled to each other in series this order. unit receives voltage node between element generates data representing voltage. calculator calculates temporal average current flowing through LEDs based on data, corresponding average. drives data.
