Document Type and Number:
Japanese Patent JP2023104353
Kind Code:
A
Abstract:
To provide an image display device, a signal processing method, and a signal processing program, which can display a high-quality image at a lower driving frequency while maintaining stability and high speed of digital driving using a pulse density driving method.SOLUTION: An image display device 1 comprises: a reference image creation section 121 that creates a reference image having a reference value as a pixel value; and a dither processing section 122 that converts a pixel value of an input video into 1 or 0 using a reference value of the same pixel as that of the input video as a threshold. The reference image creation section 121 creates a reference image group composed of a plurality of reference images in which any pixel does not have the same value, and sequentially provides the reference image from the reference image group to the dither processing section 122.SELECTED DRAWING: Figure 1
