Abstract: A prefabricated substrate, a flexible substrate, a flexible module and a fabrication method, and a display device are provided. The prefabricated substrate includes a first film layer as a rigid film layer, and a second film layer as a flexible film layer. The second film layer at least partially wraps the first film layer. The first film layer includes a first surface and a second surface. The second film layer at least includes a first portion located on a side of the first surface away from the second surface, and a second portion and a third portion located on a side of the second surface away from the first surface. The second portion and the third portion are attached on the second surface through a first adhesive layer and a second adhesive layer, respectively. The second portion and the third portion are spaced apart by a gap.

Abstract: A scanning antenna is provided in the present disclosure. The scanning antenna includes a first substrate and a second substrate which are arranged oppositely; a liquid crystal layer between the first substrate and the second substrate; and a feed signal access terminal and a plurality of phase shift units, where the plurality of phase shift units is connected with each other, each phase shift unit is connected to the feed signal access terminal, and electrical lengths between at least two phase shift units and the feed signal access terminal are different. The present disclosure not only realizes one-dimensional wave beam scanning, but also has desirable scanning effect. The bias voltage is not needed to be independently applied to each phase shift unit, which can greatly simplify the bias voltage line configuration and be beneficial for reducing production cost and wiring difficulty.
