    • PURPOSE: A light source apparatus and a display apparatus with the light source apparatus are provided to increase the voltage difference between an external voltage and a driving voltage. CONSTITUTION: A light source module comprises a light emitting group(210). A plurality of LED(Light Emitting Diode) strings are connected in parallel in the light emitting group. A plurality of LEDs is serially connected in one light emitting diode string. A voltage converting unit(250) boosts an external voltage to a driving voltage of a level higher than an initial driving voltage. A splitter(270) drops the driving voltage as much as a voltage difference between the initial driving voltage and the driving voltage. The splitter offers the dropped driving voltage to the light emitting group.
    • 目的:提供具有光源装置的光源装置和显示装置,以增加外部电压和驱动电压之间的电压差。 构成:光源模块包括发光组(210)。 多个LED(发光二极管)串在发光组中并联连接。 多个LED串联连接在一个发光二极管串中。 电压转换单元(250)将外部电压升高到高于初始驱动电压的电平。 分离器(270)将驱动电压降低到初始驱动电压和驱动电压之间的电压差。 分路器向发光组提供降低的驱动电压。
