Abstract: A display device includes: a first pixel, a second pixel, and a third pixel from which lights of different colors are respectively emitted; in the first pixel, a first light conversion layer overlapping a first color filter; in the second pixel, a second light conversion layer overlapping a second color filter; and in the third pixel, a third light conversion layer overlapping a third color filter. The first light conversion layer, the second light conversion layer, and the third light conversion layer respectively include a quantum dot, and an amount of the quantum dot included in the first light conversion layer is larger than each of amounts of the quantum dot respectively included in the second light conversion layer and the third light conversion layer.

Abstract: A driving unit of a display panel includes a control part, a gate driving part, a grayscale compensating part, and a data driving part. The control part provides a control signal and a grayscale signal. The gate driving part provides a gate signal to the display panel. The display panel is divided into a plurality of blocks according to a distance from a light source to each of the blocks. The grayscale compensating part outputs a compensating signal of an n-th frame using look-up tables, and the look-up tables respectively correspond to the blocks of the display panel. The data driving part converts the compensating signal of the n-th frame into a grayscale voltage and provides the grayscale voltage to the display panel. Accordingly, the driving unit of the display panel may improve a response speed of liquid crystals and display quality.

Abstract translation: 显示面板的驱动单元包括控制部分，门驱动部分，灰度补偿部分和数据驱动部分。 控制部分提供控制信号和灰阶信号。 门驱动部分向显示面板提供门信号。 根据从光源到每个块的距离，显示面板被分成多个块。 灰度补偿部分使用查找表输出第n帧的补偿信号，并且查找表分别对应于显示面板的块。 数据驱动部将第n帧的补偿信号转换为灰阶电压，并将灰度电压提供给显示面板。 因此，显示面板的驱动单元可以提高液晶的响应速度和显示质量。
