Abstract
The present disclosure provides a display driver module, a display apparatus and a voltage adjustment method. The display driver module comprises a source driving unit and a power supply unit. The source driving unit is configured to generate a voltage control signal according to an acquired brightness control factor, the power supply unit is configured to adjust an operating voltage output to a cathode of a light emitting device according to the voltage control signal, the operating voltage decreases or maintains unchanged as display brightness corresponding to the brightness control factor increases, and the operating voltage output by the power supply unit in response to the brightness control factor corresponding to minimum display brightness is greater than the operating voltage output by the power supply unit in response to the brightness control factor corresponding to maximum display brightness.
