A hardware accelerator for improving the decompression performance when decompressing data in Lempel-Ziv-Huffman compressed data format. The use of a Huffman encoding second stage in the popular and widely-used Lempel-Ziv-Huffman standard improves the compression ratio but complicates the decompression, because the Huffman encoding is applied selectively only to certain parts of the Lempel-Ziv tokens, and thus Huffman decoding must also be applied selectively during decompression. The present invention features a variable-length token decoder which is able to selectively decode the Huffman-encoded portions of the compressed data, and therefore enables high-performance decompression for compressed data having a very good compression ratio. Such an accelerator is well-suited for use in data processors which are to be loaded with pre-compressed data and software applications, particularly those employing flash memory.

Provided are a baseplate and a preparation method thereof, a display panel and a display device. The baseplate includes a substrate including a bendable region, an intermediate layer located on the substrate and in the bendable region, and at least one signal line located on one side of the intermediate layer far away from the intermediate layer, wherein an orthographic projection of the at leastone signal line on the substrate is located in an orthographic projection of the intermediate layer on the substrate, and at least part of the signal line is a curve, and at least one side of the partof the intermediate layer corresponding to the at least one signal line is provided with at least one groove.

The use of a Huffman encoding second stage in the popular and widely-used Lempel-Ziv-Huffman standard improves the compression ratio but complicates the decompression, because the Huffman encoding is applied selectively only to certain pails of the Lempel-Ziv tokens, and thus Huffman decoding must also be applied selectively during decompression. The present invention features a variable-length token decoder which is able to selectively decode the Huffman-encoded portions of the compressed data, and therefore enables high-performance decompression for compressed data having a very good compression ratio.
