Abstract: 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.

Abstract: A timing control (TCON) board and a display device are provided. The TCON board includes a TCON chip and a CB. A plurality of heat dissipating terminals are provided to commonly connect the TCON chip to the CB, increasing a total contact area of the TCON board and the CB. Therefore, heat dissipation efficiency of the TCON chip is improved. At the same time, the heat dissipating terminals greatly reduce a pseudo connection percentage. Hence, heat dissipation performance and electrical performance of the entire TCON chip are avoided to be impacted.

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: The present invention provides a timing controller and a controlling method thereof, and a display device with the timing controller. The timing controller includes a storage control module and a frame buffer module connected to each other, and a self-refresh interface connected to the front-end system chip. When the front-end system chip displays a static screen image, the timing controller provided by the present invention can only maintain internal essential modules working and suspend other modules on standby, which reduces power consumption of the timing controller and enhances an operation life of the display device with the timing controller.
