    • A backlight apparatus and a display apparatus are provided. The backlight apparatus includes N first switch units to switch a plurality of currents flowing in respective N light emitting element arrays according to an input brightness control signal, N second switch units to switch a plurality of currents flowing in respective N capacitors according to the input brightness control signal, and a reference current generation unit to generate and output a reference current based on the input brightness control signal. An inverter unit adjusts a total current supplied to all of the light emitting element arrays in total to be equal to the reference current if the total current is different from the reference current.
    • 提供背光装置和显示装置。 背光装置包括N个第一开关单元,用于根据输入亮度控制信号切换在各N个发光元件阵列中流动的多个电流,N个第二开关单元,用于根据输入亮度切换流入各N个电容器中的多个电流 控制信号和参考电流产生单元,以基于输入亮度控制信号产生和输出参考电流。 如果总电流与参考电流不同,则逆变器单元将提供给所有发光元件阵列的总电流总计为等于参考电流。
