1. A full-screen display device, comprising:
a display substrate having a light emitting side and comprising:
a first display sub-region comprising a first pixel unit and a second pixel unit, wherein the first pixel unit comprises a first sub-pixel and a second sub-pixel, and the second pixel unit comprises a second sub-pixel and a third sub-pixel; and
a second display sub-region comprising a repeating unit comprising a third pixel unit and a first transparent pixel, wherein the third pixel unit comprises a first sub-pixel, a second sub-pixel, and a third sub-pixel, and wherein the first transparent pixel is not provided with a light emitting functional layer and allows ambient light to transmit; and
an under-screen camera attached onto a side of the display substrate opposite to the light emitting side and configured to receive ambient light passing through the second display sub-region for imaging, wherein an orthographic projection of the under-screen camera on the display substrate falls within the second display sub-region and has an overlap with the first transparent pixel,
wherein the first transparent pixel is configured such that a pixel density of the second display sub-region is smaller than that of the first display sub-region, and a light transmittance of ambient light of the second display sub-region is greater than that of the first display sub-region,
wherein an area of the first transparent pixel is greater than or equal to a sum of areas of the first sub-pixel, the second sub-pixel, and the third sub-pixel in the third pixel unit,
wherein the first pixel unit and the second pixel unit disposed adjacently in the first display sub-region constitutes a first repeating unit, and the first repeating unit is configured to be driven in a sub-pixel borrowing manner,
the third pixel unit and the first transparent pixel disposed adjacently in the second display sub-region constitutes a second repeating unit, and the second repeating unit is configured to be driven in a manner in which no sub-pixel is borrowed,
the first sub-pixel, the second sub-pixel, and the third sub-pixel in the third pixel unit have substantially the same first shape, and the first sub-pixel, the second sub-pixel, and the third sub-pixel in the first pixel unit and the second pixel unit have substantially the same second shape, and
the first shape is different from the second shape.
