Abstract
Disclosed is a display apparatus. The display apparatus includes: a transformer, voltage conversion modules, a feedback module and a light string group. The light string group includes a first light string and a second light string; a first secondary coil and a second secondary coil of the transformer are coupled with a primary coil of the transformer; the first secondary coil is configured to output a first voltage according to a power received by the primary coil. The second secondary coil is configured to output a second voltage from both ends of the second secondary coil alternately according to the power received by the primary coil. The voltage conversion module is configured to generate an additional voltage according to the first voltage, and superimpose the additional voltage onto a corresponding second voltage at both ends of the second secondary coil to output a superimposed third voltage.
