摘要： 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.

摘要： A method of preventing a backlight module from overheating and a display device are provided. The method can prevent backlight partitions from having a long-time high-brightness operation and causing the backlight module to overheat by obtaining a driving current of each backlight partition in the backlight module, judging whether a brightness of each backlight partition in the backlight module exceeds a reference brightness, and adjusting the brightness of each backlight partition that exceeds the reference brightness to a target brightness.

摘要： A timing controller is provided. A data enable signal in a timing control module is regenerated by a signal regenerating module. A number of vertical valid display rows is regenerated as a vertical valid display period. A total charge time of all rows of pixels in each frame can be increased effectively. A horizontal blanking period is changed sequentially in a row-by-row manner, thereby compensating charge effects of rows of pixels accurately.

摘要： A display apparatus and a mobile terminal are provided. The display apparatus includes a display panel, N2 data drives, and a timing controller. Video data can be transmitted to a plurality of input video interfaces corresponding to the data drives in a time-sharing manner using one output video interface of the timing controller. Therefore, a timing controller with relatively low resolution can be matched with a display panel with relatively high resolution, thereby reducing overall costs of the display apparatus.
