Description

technical field [0001] The present invention relates to a self-luminous display, and more particularly to a self-luminous display with repair electrodes. Background technique [0002] With the advancement of semiconductor technology, today's light-emitting diodes have a high-brightness output. In addition, light-emitting diodes have the advantages of power saving, small size, low-voltage drive, and mercury-free. Therefore, light-emitting diodes have been widely used in displays and Lighting and other fields to form a self-luminous display. [0003] Generally speaking, the self-luminous display uses a mechanical device or a stamp (PDMS) transfer method to mount the light-emitting diodes on the substrate. However, alignment and accuracy problems may occur during the transfer printing process, resulting in the inability to connect the light emitting diodes to the correct electrodes and reducing the yield of the self-luminous display. Contents of the invention [0004] The i...
