1. A display driving device, comprising:
a timing controller circuit, configured to perform oblique filter processing on an original image frame by an oblique filter with an oblique filter mask matrix to generate a processed image frame, wherein the oblique filter comprises an oblique high-pass filter or a smoothing filter, and original pixel data of a current pixel in the original image frame is replaced with new pixel data when the oblique filter mask matrix is configured for the current pixel; and
a driving circuit, coupled to the timing controller circuit to receive the processed image frame, configured to drive a display panel module according to the processed image frame,
wherein the display panel module comprises a tilt lenticular lens layer having a first tilt angle, and a second tilt angle of the oblique filter mask matrix of the oblique filter processing corresponds to the first tilt angle, wherein coordinates of a pixel in the original image frame corresponding to an element in the oblique filter mask matrix are [cos(θ2)*x1−sin(θ2)*y1, sin(θ2)*x1+cos(θ2)*y1], wherein θ2 is the second tilt angle, x1 is x0+s, y1 is y0+t, x0 is an x component of coordinates of the current pixel in the original image frame, y0 is a y component of the coordinates of the current pixel, s is an integer in a range of −a to a, t is an integer in a range of −b to b, a is a radius of the oblique filter mask matrix in an X-axis direction, and s is a radius of the oblique filter mask matrix in a Y-axis direction.
