Abstract
Herein disclosed are a micro-component transfer head, a micro-component transfer device, and a micro-component display. Said micro-component transfer head comprises a carrying surface that corresponds to a micro-component extraction area. Said extraction area conforms with a first geometric object, which comprises at least an acute angle. A second geometric object comprises at least a right angle and is constituted of n copies of the first geometric object, n being an integer greater than 1. The shape of the first geometric object differs from that of the second.
Claims16
A micro-component transfer head, comprising:
- a carrying surface corresponding to a micro-component extraction area;
- and
- a side when looked from the outside of the micro-component transfer head and that is opposite to and farthest from the carrying surface, wherein the shape of the side differs from the shape of the first geometric object, and an area of said other side is greater than an area of the carrying surface;
- wherein the micro-component extraction area conforms with a first geometric object, the first geometric object comprises at least an acute angle, and n copies of the first geometric object constitute a second geometric object, n being an integer greater than 1;
- wherein the second geometric object comprises at least a right angle, the first geometric object is dissimilar in shape to the second geometric object, the carrying surface is configured to extract, when coming into contact with a surface of a wafer, a plurality of micro-components situated at the surface of the wafer and within the micro-component extraction area, the orthogonal projection of the micro-component extraction area on the surface of the wafer is the first geometric object, and the orthogonal proj ection of the carrying surface on the surface of the wafer defines the micro-component extraction area.
A micro-component transfer device, configured to extract a plurality of micro-components in a wafer, and comprising:
- a platform configured to hold the wafer;
- and
- a micro-component transfer head positioned opposite the platform and comprising:
- a carrying surface corresponding to a micro-component extraction area;
- and
- a side when looked from the outside of the micro-component transfer head and that is opposite to and farthest from the carrying surface, wherein the shape of the side differs from the shape of the first geometric object, and an area of said other side is greater than an area of the carrying surface;
- wherein the micro-component extraction area conforms with a first geometric object, the carrying surface is configured to extract, when coming into contact with a surface of the wafer, the micro-components situated at the surface of the wafer and within the micro-component extraction area, the orthogonal projection of the micro-component extraction area on the surface of the wafer is the first geometric object, and the orthogonal projection of the carrying surface on the surface of the wafer defines the micro-component extraction area, and a first end of the first geometric object is generally aligned with the center of the wafer.
A micro-component display, comprising:
- a receiving substrate having a display surface, the display surface comprising a plurality of micro-component carriage areas;
- wherein each of the micro-component carriage areas conforms with a first geometric object;
- wherein the first geometric object comprises at least an acute angle, and within each of the micro-component carriage areas there are a plurality of micro-components;
- wherein every two adjacent micro-components within the same one of the micro-component carriage areas and arranged in a row/column direction are spaced a first distance apart, every two adjacent micro-components respectively within different ones of the micro-component carriage areas and arranged in the row/column direction are separated by at least a second distance, the first distance being unequal to the second distance, and the micro-component carriage areas fill up the display surface.
