Abstract
The present disclosure provides a display substrate, a method for preparing the same, and a display device. The display substrate includes: a base substrate; a display function layer located on the base substrate, a first groove arranged in the first surface, and a first connection sub-line located in the first groove and covering a bottom and each side wall of the first groove, the first connection sub-line being connected to a signal input terminal; an integrated circuit located on a second surface, a second groove arranged in the second surface, and a second connection sub-line located in the second groove, the second connection sub-line being connected to the first connection sub-line and a signal output terminal of the integrated circuit.
Claims20
A display substrate, comprising:
- a base substrate;
- a display function layer located on a first surface of the base substrate, a first groove arranged in the first surface and recessed from the first surface toward the base substrate, and a first connection sub-line located in the first groove and covering a bottom and each side wall of the first groove, wherein the first connection sub-line is connected to a signal input terminal of the display function layer;
- and
- an integrated circuit located on a second surface of the base substrate opposite to the first surface, a second groove arranged in the second surface and recessed from the second surface toward the base substrate to the first connection sub-line, and a second connection sub-line located in the second groove, wherein the second connection sub-line is connected to the first connection sub-line and a signal output terminal of the integrated circuit,
- wherein an orthogonal projection of the first groove on the base substrate at least partially overlaps an orthogonal projection of the second groove on the base substrate, and the first groove and the second groove communicate with each other and together penetrate the base substrate.
A method for preparing a display substrate, comprising:
- providing a base substrate;
- etching the base substrate to form a first groove in the first surface of the base substrate which recesses from a first surface to the base substrate;
- forming a first connection sub-line in the first groove which covers a bottom and each side wall of the first groove;
- forming a display function layer on the first surface, a signal input terminal of which is connected to the first connection sub-line;
- etching the base substrate from a second surface of the base substrate opposite to the first surface to form a second groove for exposing the first connection sub-line;
- and
- forming a second connection sub-line connected to the first connection sub-line in the second groove,
- wherein an orthogonal projection of the first groove on the base substrate at least partially overlaps an orthogonal projection of the second groove on the base substrate, and the first groove and the second groove communicate with each other and together penetrate the base substrate.
