Abstract: The present application provides a display device driving control circuit assembly and a display device. In the present application, a frequency of the first timing control clock of the first timing controller and a frequency of the second timing control clock of the second timing controller are different, as a result, a radiation intensity generated by the first timing controller and the second timing controller during operation is greatly reduced, thereby greatly reducing an intensity of electromagnetic compatibility.

Abstract: An encoding method, a decoding method, an encoding device and a decoding device are provided. The encoding method includes: obtaining a first bit stream of an original encoded data; determining whether a number of the successive bits is greater than a predetermined number; if the number of the successive bits is greater than the predetermined number, then selecting at least one target bit from the successive bits; performing a logic NOT operation on the target bit to obtain a symbol bit; and inserting the symbol bit to the successive bits to obtain an encoded bit stream. The present disclosure could raise the encoding speed and reliability.

Abstract: A mini LED backlight module, a driving circuit and a display device are provided. Emitting units of the same row in the mini LED backlight module are divided into multiple sections that could be illuminated differently. This could avoid the issue of a high backlight current pulse when each row of light emitting units in different backlight sections is simultaneously illuminated and thus alleviate the issue of reducing the lifetime of light emitting units.
