Abstract: A display device and a controlling method thereof are provided. The display device includes a display panel, a backlight unit, and a time schedule controller. The display panel is configured to display images. Areas where afterimages of dynamic images occur are identified according to comparison results of dither values. Tailing phenomenon of the dynamic images may be relieved by transmitting backlight data without brightness to a second backlight sub-area corresponding to where the afterimages occur. Furthermore, because frequency multiplication is not applied, risks of display instability will not increase.

Abstract: A QLED light-emitting device is provided, including a first electrode layer, an electron injection layer, an electron transport layer, a light-emitting layer, a hole transport layer, a hole injection layer, and a second electrode layer. Wherein, the light-emitting layer includes a plurality of quantum dot layers disposed in a stack, and insulating layers are disposed among the quantum dot layers adjacent to one side of the electron injection layer. Through disposing the insulating layers among the quantum dot layers adjacent to the one side of the electron injection layer, an electron transmission rate is reduced, thereby balancing the electron transmission rate and a hole transmission rate and improving luminous efficiency of QLEDs.

Abstract: Please replace Abstract with the following amended Abstract: A reference voltage generation circuit is provided. The reference voltage generation circuit reduces a potential difference between a reference voltage less than a first data driving voltage and a data driving voltage, namely, the potential difference between a lower reference voltage and the data driving voltage is reduced. Therefore, the power loss of a voltage dividing module is reduced to prevent the problems of reduced reliability and reduced service life of a drive circuit board due to excessive internal temperature.
