1. A display device, comprising a management chip and a display screen and a display panel, the management chip and the display screen are disposed on the display panel, wherein the management chip is connected to the display screen through data connection lines, and the display screen comprises a plurality of display circuits and a plurality of first function circuits, and each of the display circuits comprises a plurality of display units, and each of the first function circuits comprises a plurality of first function units, and the plurality of first function units are arranged between adjacent display units, and each of the display circuits is provided with a driving circuit; wherein
the management chip is employed to determine initial pixel driving data of an image to be displayed according to the image to be displayed, which is received, and pack the initial pixel driving data into a plurality of pixel driving data blocks according to parameters of the display circuits, and write the pixel driving data blocks to the driving circuits of the corresponding display circuits through the data connection lines based on control signals;
the driving circuit of the display circuits is employed to drive pixels in the display circuits to work according to the pixel driving data block, which is received, wherein a peak value of a processing capability of the driving circuit is greater than or equal to processing parameters required for processing the pixel driving data block;
wherein the management chip comprises a function processing circuit, and the function processing circuit is configured to:
obtain a resolution of the display screen and arrangement parameters of the display circuits before the management chip is employed to determine initial pixel driving data of an image to be displayed according to the image to be displayed, which is received, wherein the resolution of the display screen is determined by resolutions of the display circuits and the arrangement parameters of the display circuits; and
under a condition that a resolution of the image to be displayed is higher than the resolution of the display screen, down-sample the image to be displayed so that a resolution of the image to be displayed, which is processed, is same as the resolution of the display screen, or under a condition that a resolution of the image to be displayed is lower than the resolution of the display screen, add redundant pixel rows and/or add redundant pixel columns to the image to be displayed, so that a resolution of the image to be displayed, which is processed, is same as the resolution of the display screen.
