Abstract
A display substrate, a manufacturing method thereof, and a display apparatus are provided. The display substrate includes a display region and a non-display region surrounding the display region, and the non-display region includes a bending region and a buffer structure. The bending region is coated with a rheological material, and the buffer structure is arranged in the bending region and configured to block the rheological material from flowing out of the bending region.
Claims17
A display substrate, comprising:
- a display region and a non-display region surrounding the display region;
- and
- a buffer structure;
- wherein the non-display region comprises a bending region, and the buffer structure is in the bending region and configured to block a rheological material from flowing out of the bending region,
- wherein the bending region comprises at least one curved edge and at least one non-curved edge;
- and the buffer structure comprises a wall along the at least one non-curved edge,
- wherein the number of the at least one non-curved edge is two, and the two non-curved edges are opposite to each other;
- and wherein the number of the wall is two, and the two walls are along the two non-curved edges respectively,
- the buffer structure comprises a plurality of barriers or a plurality of grooves between the two walls.
A method for manufacturing a display substrate, comprising:
- forming a buffer structure in a bending region of a non-display region surrounding a display region, the buffer structure being configured to block a rheological material from flowing out of the bending region,
- wherein the forming a buffer structure in a bending region of a non-display region surrounding a display region further comprises:
- forming an insulating material layer in the bending region, and applying a photoresist to the insulating material layer, wherein the bending region comprises at least one curved edge and at least one non-curved edge;
- forming a photoresist reserved region and a photoresist removal region after exposing and developing the photoresist, wherein the photoresist reserved region extends along the at least one non-curved edge;
- and
- removing the insulating material layer in the photoresist removal region, and stripping the photoresist of the photoresist reserved region, to form a wall extending along the at least one non-curved edge, wherein the buffer structure comprises the wall.
A method for manufacturing a display substrate, comprising:
- forming a buffer structure in a bending region of a non-display region surrounding a display region, the buffer structure being configured to block a rheological material from flowing out of the bending region,
- wherein forming the buffer structure in the bending region of the non-display region surrounding the display region:
- forming a wall extending along at least one non-curved edge of the bending region by an ink-jet printing process with an insulating material, wherein the bending region comprises at least one curved edge and the at least one non-curved edge, and the buffer structure comprises the wall.
