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: The present disclosure discloses a driving circuit and a display panel. The driving circuit includes: a first wire; a second wire; and a plurality of third wires, spaced apart from each other, wherein one end of each third wire is electrically connected to the first wire, and an other end of the each third wire is electrically connected to the second wire. A current adjustment unit and at least one light-emitting unit are disposed on the each third wire. Each current adjustment unit has a different resistance value. The current adjustment unit on the each third wire that is farther away from a first signal input terminal of the first wire has a smaller resistance value.

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.

Abstract: The present disclosure provides an array substrate and a manufacturing method of the array substrate. In the manufacturing method of the array substrate, during performing a first wet etching and a second wet etching on a second metal layer, the wet etching is stopped when a copper conductive layer is merely etched completely. Because a wet etching speed of a liner layer is slow, an etching time of the wet etching and a CD loss of the copper conductive layer can be greatly reduced, and the CD loss is relatively small. Meanwhile, an entire CD loss of the second metal layer can be reduced, and an aperture ratio can be improved.

Abstract: The present invention provides a liquid crystal display panel and an alignment method of the liquid crystal display panel. By inputting a voltage equal to a pixel voltage into data black-matrix less (DBS) electrodes at a gray scale 255, rotation of liquid crystals at the DBS electrodes can be consistent with rotation of liquid crystals at the pixel electrodes during an alignment process. Therefore, the present invention improves brightness at the DBS electrodes of the liquid crystal display panel at the gray scale 255, and increases light transmittance of the liquid crystal display panel.
