DISPLAY DRIVING DEVICE, DISPLAY DEVICE, AND DISPLAY DRIVING METHOD

The invention discloses a display driving device, a display device and a display driving method.The display driving device comprises a time schedule controller and a gate driving circuit, and the time schedule controller is configured to control the refresh rate of a frame in a frame period when it is detected that the refresh rate of an image display state is smaller than or equal to a preset threshold value; controlling the gate driving circuit to scan pixel unit rows of the display panel in n time periods, and when the total row number N of the pixel unit rows can be exactly divided by n, scanning the (i + (j-1). N) th row of the pixel unit rows in the ith time period, i = 1, 2,..., n; j = 1, 2,..., N/n, when the total row number N of the pixel unit rows cannot be exactly divided by n, the (i + (j-1). N) th row of the pixel unit rows is scanned in the ith time period, and i = 1, 2,..., n; j is 1, 2,..., (N + n-i)/n, and the number of rows obtained after j is valued is smaller than or equal to N.
