  • Patent number: 11756462
    Abstract: The disclosure provides a display driving device and an operation method thereof. The display driving device includes a timing controller circuit and a driving circuit. The timing controller circuit performs oblique filter processing on an original image frame by an oblique filter with an oblique filter mask matrix to generate a processed image frame. The oblique filter comprises an oblique high-pass filter or a smoothing filter. 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. The driving circuit drives a display panel module according to the processed image frame. The display panel module includes a tilt lenticular lens layer having a first tilt angle. A second tilt angle of the oblique filter mask matrix of the oblique filter processing corresponds to the first tilt angle.
