Abstract:
1. A three-dimensional (3D) television (TV) dimming system, comprising: a TV control board; a light bar load controlled by the TV control board; and a power board that supplies power to the light bar load, wherein the TV control board is directly coupled to the power board and outputs a 3D signal that is fed back to the power board; wherein the power board comprises a first comparator, a second comparator, a third comparator, and an output circuit; an output end of the first comparator and an output end of the second comparator are directly coupled to an input end of the third comparator; an input end of the first comparator is directly coupled to the TV control board, and an output end of the third comparator is directly coupled to an input end of the output circuit; wherein the output circuit comprises a fourth comparator directly coupled to the output end of the third comparator, and a trigger directly coupled to an output end of the fourth comparator; wherein the light bar load comprises a light bar and a converter; the converter is directly coupled to an output end of the TV control board, and the TV control board sends the 3D signal to the converter when the TV control board feeds back the 3D signal to the power board.
