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. 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.
