C2 SYMMETRIC LED ELEMENT AND METHOD FOR MANUFACTURING DISPLAY MODULE BY USING ARRANGEMENT OF C2 SYMMETRIC LED ELEMENT USING WAVE ENERGY

摘要

The present invention provides an LED element, in which the flat surface of a substrate is patterned in a C2 symmetric shape so that the top, bottomw, right, and left can be distinguished. In addition, with regard to the arrangement of electrodes, an electrode of one conductivity type is disposed at the center of the substrate and electrodes of a different conductivity type are arranged at positions spaced the same distance in opposite directions from the electrode, so that electrode matching is achieved in any case even if the electrode matching is attempted after rotation of 180 degrees. In addition, the present invention relates to arranging C2 symmetric LED elements by using wave energy and manufacturing a display module by using the arranged C2 symmetric LED elements. In the present invention, since the C2 symmetric LED element is an element capable of achieving 180-degree rotational symmetry, elements can be arranged highly precisely and in a manner enabling distinguishment between the top, bottom, right, and left.
