Abstract
The present disclosure provides a display panel and preparing method thereof, and a display apparatus. In one or more embodiments, the display panel includes a substrate that includes an off-screen camera region including a plurality of opening regions, a flexible layer located at a side of the substrate, a backplate layer located at a side of the flexible layer away from the substrate and including a plurality of light-transmitting film layers, and a light-emitting device layer located at a side of the backplate layer away from the substrate and including a plurality of cathodes. An orthographic projection of the flexibly layer on the substrate is not overlapped with the opening regions. An orthographic project of at least one light-transmitting film layer on the substrate covers the opening regions. Orthographic projections of the cathodes on the substrate are not overlapped with the opening regions.
