    • A display apparatus includes a backlight unit which emits a light, and a display panel which receives the light to display an image. The backlight unit includes a driving circuit which outputs a driving voltage and a reference voltage; and p light source blocks connected to the driving circuit, p being a natural number greater than or equal to 2, where each light source block of the p light source blocks receives the driving voltage through a first terminal thereof and the reference voltage through a second terminal thereof to generate the light, and the p light source blocks are divided into a plurality of groups, each group including at least two light source blocks. The driving circuit includes a first switching section which applies the driving voltage to first terminals of the p light source blocks, and a second switching section which applies the reference voltage to the second terminal of at least one of the p light source blocks.

    • A backlight unit includes a driving circuit, a plurality of light source strings, and an error detector. The driving circuit outputs a driving voltage. Each of the light source strings includes a plurality of light sources and receives the driving voltage through input terminals of the light source strings to generate a light. The error detector is connected to output terminals of the light source strings and senses voltages between the input terminals and the output terminals of the light source strings to detect an error in the light sources using a first voltage and a second voltage. The first voltage is a voltage difference between a maximum and a minimum of the sensed voltages and the second voltage is obtained by dividing one sensed voltage of the sensed voltages by a number of the light sources of a light source string from which the one sensed voltage is sensed.
    • 背光单元包括驱动电路,多个光源串和误差检测器。 驱动电路输出驱动电压。 每个光源串包括多个光源,并且通过光源串的输入端接收驱动电压以产生光。 误差检测器连接到光源串的输出端,并感测输入端和光源串的输出端之间的电压,以使用第一电压和第二电压来检测光源中的误差。 第一电压是感测电压的最大值和最小值之间的电压差,并且第二电压是通过将感测电压的一个感测电压除以光源串的光源数量而获得的, 被感测。
