摘要: A display driving circuit includes a temperature compensation adjustment circuit, a control circuit, a full bridge circuit, and a transformation circuit. The temperature compensation adjustment circuit provides a current signal for the control circuit. The value of the current signal changes along with environment temperature changes. The control circuit controls the full bridge circuit based on the current signal. An output voltage signal of the full bridge circuit decreases as the current signal increases, and when the environment temperature decreases. The transformation circuit amplifies the output voltage signal of the full bridge circuit to drive a display.

摘要: A light source driving device includes a power stage circuit, a first transformer circuit, a second transformer circuit, and a feedback control circuit. The power stage circuit converts a received signal to an alternating current (AC) signal, which includes a synchronizing switching bridge arm, a first bridge arm, and a second bridge arm. The synchronizing switching bridge arm has a Soft-Switching function, and forms a first full-bridge circuit with the first bridge arm and forms a second full-bridge circuit with the second bridge arm. The first transformer circuit is connected to the first full-bridge circuit, for converting the AC signal. The second transformer circuit is connected to the second full-bridge circuit, for converting the AC signal. The feedback control circuit is connected between the light source module and the power stage circuit, for controlling output of the power stage circuit.

摘要: A power system for driving plural or multiple lamps includes a transformer circuit, a filter and steady-flow circuit, and a light source. The transformer circuit transforms a voltage level of an input AC signal, and includes a first output end for outputting a first AC signal, and a second output end for outputting a second AC signal. The first and second AC signals are opposite in phase. The filter and steady-flow circuit includes a first plurality of filter and steady-flow units connected to the first output end for suppressing harmonic signals of the first AC signal and outputting a plurality of third AC signals. The light source has a first plurality of lamps, each of which having one end connected to one of a respective one of the first plurality of filter and steady-flow units so as to be driven by a respective one of the third AC signals.
