The block diagrams depicted in the figures are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, or in one or more software-hardened modules, or in different networks and/or processor devices and/or microcontroller devices.

In order to realize the full screen display technology, the front camera can be arranged below the display screen. For the purpose of the under-screen image capturing, as shown in fig. 1, an under-screen image capturing area 01, a transition area 02, and a normal display area 03 may be provided on the display screen, the transition area 02 being provided between the under-screen image capturing area 01 and the normal display area 03. The pixel density of the under-screen image pickup region 01 is smaller than that of the normal display region 03 and that of the transition region 02, and the pixel density of the transition region 02 is smaller than that of the normal display region 03.

The under-screen camera shooting area 01 can transmit light, and light enters a camera arranged under a display screen through the under-screen camera shooting area 01 to image. In the display screen, the pixel circuits are required to drive the corresponding pixel units to emit light, so that in order to avoid the influence of the pixel circuits on the light transmittance of the under-screen image pickup area 01, the pixel circuits corresponding to the under-screen image pickup area 01 can be arranged in the transition area 02.
