Abstract: The present disclosure relates to a matrix transposition device and method, and a display device. The matrix transposition device includes a first counting unit, an input module, second counting units, and a first data selection unit. The first counting unit numbers a matrix element and outputs a first signal. The input module is coupled to the first counting unit, and is input with the matrix element after receiving the first signal. Each column of matrix elements corresponds to one of the second counting units, each of the second counting units outputs a set of second signals, and each set of the second signals includes number information of the matrix elements in a column corresponding to the second counting unit. The first data selection unit receives the second signals in an order of columns of a matrix, and orderly outputs column elements of the matrix as row elements of a transposed matrix.
