Abstract
Provided is a display substrate, a preparation method thereof and a display apparatus. The display substrate includes a base substrate, which has a display area and an encapsulation area, the encapsulation area surrounds the display area, and a hydrophobic structure is arranged on the encapsulation area.
Claims18
A display substrate, comprising a base substrate, the base substrate having a display area and an encapsulation area, the encapsulation area surrounding the display area, and a hydrophobic structure being arranged on the encapsulation area,
- wherein the hydrophobic structure comprises a plurality of hydrophobic columns arrayed in the encapsulation area, and gaps are arranged between the hydrophobic columns;
- wherein height h of the hydrophobic columns and distance d between two adjacent hydrophobic columns satisfy:
- h/d>0.5, wherein 0.5 microns<h<5 microns;
- and
- wherein the distance d between two adjacent hydrophobic columns is smaller than a size of an ink drop, and the ink drop is separated from a side of the hydrophobic structure away from the base substrate.
