Abstract: 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.

Abstract: An electrostatic ignition protection method of a source driver of a display device and a display device are provided. When a time controller detects that a source driver has static electricity, the time controller controls the source driver not to output a driving signal for a preset duration and the preset duration is greater than an ignition threshold duration. This prevents the source driver having static electricity from accumulating enough heat in a short time to burn and fire.

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 timing controller, a display panel and a driving method are proposed. The display panel includes a display sub-pixel and a virtual sub-pixel. The display sub-pixel includes first sub-pixels, second sub-pixels and third sub-pixels. If the grayscale information of the two adjacent first sub-pixels are the same, then a driving signal of the virtual sub-pixel is the same as a driving signal of a third sub-pixel close to the virtual sub-pixel; otherwise, the driving signal of the virtual sub-pixel is the same as a driving signal of the third sub-pixels, which are outnumbered in the histogram.

Abstract: 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.

Abstract: The present invention provides a test method and a device of data mischarging of a display panel. The test method includes: a personal computer (PC) controlling a pixel group to output a screen with a solid color; controlling a charging time of a master device to be constant and adjusting a charging time of a timing controller; determining whether a measurement data of an optical test instrument is greater than a first threshold and detecting whether an obvious boundary appears in a middle of the display panel, and determining a mischarging time if so.

Abstract: A method of V-By-One (VBO) signal processing for saving hardware resources, and a device and terminal thereof are provided. The method includes steps of: obtaining a plurality of VBO signals transmitted through data lanes respectively and having a same descrambling reset flag; resolving each of the VBO signals to obtain a valid data strobe signal; selecting one valid data strobe signal as a synchronization strobe signal and performing time-delay processing to obtain a delay strobe signal; and writing signals alternately into a first register and a second register under control of the synchronization strobe signal and reading signals alternately from the second register and the first register under control of the delay strobe signal based on the same descrambling reset flag.

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.
