Abstract: The present disclosure provides a light-emitting diode (LED) touch panel and its driving method and preparation method. Under switching transistors of touch units controlled by touch addressing lines, electric charges accumulated in a touch conductive layer are extracted into a touch reading line to determine touch-point coordinates, thereby embedding the touch units into sub-pixels of the mini LED touch panel to form a mini LED-based embedded touch panel.

Abstract: A video encoding method is provided. The method includes decoding intra-frame prediction mode information corresponding to a current decoding unit, decoding first identification information corresponding to the current decoding unit when the intra-frame prediction mode information indicates that a block differential pulse code modulation (BDPCM) mode is applied to the current decoding unit, determining, when the first identification information indicates that a transform block (TB) corresponding to the current decoding unit does not include any non-zero transform coefficients, that a residual block corresponding to the current decoding unit is an all-zero residual block, and reconstructing the current decoding unit according to the residual block and a prediction block corresponding to the current decoding unit. The technical solutions provided in embodiments of this application improve the encoding and decoding efficiency of the decoding unit using the BDPCM mode.
