A display driving method for pixel display of pixel units of a display device, which comprises a pixel array including a first view pixel unit and a second view pixel unit alternately arranged in the row direction, said pixel array includes in each row sub-pixels corresponding to one color, each of the first and second view pixel units (12, 13) comprises a plurality of physical pixel units cyclically arranged in the column direction, and each physical pixel unit includes a plurality of sub-pixels, the method comprising: obtaining an input signal of each sub-pixel in each physical pixel unit of the first and second view pixel units (12, 13); setting a sampling region on the pixel array for each sub-pixel in the first and second view pixel units (12, 13); and determining an output signal of each sub-pixel based on the sampling region of each sub-pixel, the physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel, and the input signal of each sub-pixel, characterized in that: the step of setting the sampling region on the pixel array for each sub-pixel in the first and second view pixel units (12, 13) comprises setting the sampling region on the pixel array for each sub-pixel of the physical pixel units, which are located on boundaries of the pixel array of the display device, in the first and second view pixel units (12, 13); wherein the boundaries of the sampling region of said sub-pixel on the side of an adjacent sub-pixel of the same kind are on an axis vertically and equally dividing a line connecting the center of said sub-pixel and the center of the adjacent sub-pixel of the same kind, other boundaries of the sampling region are boundaries of pixel array of the display device; the sub-pixel of the same kind refers to a sub-pixel which belongs to the same kind of view pixel unit and has the same color as the sub-pixel; and the step of determining the output signal of each sub-pixel based on the sampling region of each sub-pixel, the physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel, and the input signal of each sub-pixel comprises: in the pixel array of the display device, obtaining the physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel; calculating the proportion of each physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel to the sampling region; and calculating to obtain the output signal of each sub-pixel based on the input signal of the sub-pixel and the proportion of each physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel to the sampling region. obtaining an input signal of each sub-pixel in each physical pixel unit of the first and second view pixel units (12, 13); setting a sampling region on the pixel array for each sub-pixel in the first and second view pixel units (12, 13); and determining an output signal of each sub-pixel based on the sampling region of each sub-pixel, the physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel, and the input signal of each sub-pixel, the step of setting the sampling region on the pixel array for each sub-pixel in the first and second view pixel units (12, 13) comprises setting the sampling region on the pixel array for each sub-pixel of the physical pixel units, which are located on boundaries of the pixel array of the display device, in the first and second view pixel units (12, 13); wherein the boundaries of the sampling region of said sub-pixel on the side of an adjacent sub-pixel of the same kind are on an axis vertically and equally dividing a line connecting the center of said sub-pixel and the center of the adjacent sub-pixel of the same kind, other boundaries of the sampling region are boundaries of pixel array of the display device; the sub-pixel of the same kind refers to a sub-pixel which belongs to the same kind of view pixel unit and has the same color as the sub-pixel; and the step of determining the output signal of each sub-pixel based on the sampling region of each sub-pixel, the physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel, and the input signal of each sub-pixel comprises: in the pixel array of the display device, obtaining the physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel; calculating the proportion of each physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel to the sampling region; and calculating to obtain the output signal of each sub-pixel based on the input signal of the sub-pixel and the proportion of each physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel to the sampling region. in the pixel array of the display device, obtaining the physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel; calculating the proportion of each physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel to the sampling region; and calculating to obtain the output signal of each sub-pixel based on the input signal of the sub-pixel and the proportion of each physical pixel unit overlapping the sampling region and belonging to the same view pixel unit as the sub-pixel to the sampling region.
