Abstract:
1. A driving circuit of a matrix device, which is applied to the matrix device having a plurality of functional elements arranged in a matrix, which is connected to the functional elements via data lines, and which has a plurality of blocks, comprising: a shift register which has a plurality of register sections, each of the register sections being corresponding to one of the plurality of blocks; a data signal line; a first data latch circuit connected to an output terminal of the shift register and the data signal line; and a second data latch circuit connected to the output terminal of the shift register and an output terminal of the first data latch circuit, and connected to the data line directly or via another circuit, wherein the first and second data latch circuits are respectively divided into multistage operation units, each of the operation units being corresponding to the one data line or the plurality of data lines and being corresponding to one of the plurality of blocks, and wherein a first output terminal outputting from the shift register section corresponding to a block B is connected to transfer a signal to the operation unit of the first data latch circuit corresponding to the block B, a second, distinct output terminal outputting from the shift register section corresponding to a block A is directly connected to transfer a signal to the operation unit of the second data latch circuit corresponding to the block B, and each of the block A and block B is one of the plurality of blocks.
