Abstract

The invention provides a touch control type miniature light emitting diode display which comprises a semiconductor lamination layer, a plurality of under-bump metallization layers and at least one first sensing pattern are arranged on the upper surface of the semiconductor lamination layer, the under-bump metallization layers and the at least one first sensing pattern have the same material and thickness, and the at least one first sensing pattern is arranged on the upper surface of the semiconductor lamination layer. The under bump metallization layers extend downwards into the semiconductor lamination layer and are electrically connected with a plurality of corresponding conductive structures under the under bump metallization layers respectively; the plurality of first conductive bumps are electrically connected with the corresponding under-bump metallization layers below the first conductive bumps respectively; the at least one bonding pad is configured on the at least one first sensing pattern and partially overlaps with the at least one first sensing pattern, and the at least one bonding pad and the first conductive bumps have the same material and thickness; the plurality of second conductive bumps are electrically connected with the corresponding first conductive bumps below respectively; and a plurality of micro light-emitting diodes disposed on the second conductive bumps.

Description

technical field [0001] The present invention relates to a display and a manufacturing method thereof, and more particularly, to a touch-sensitive micro light-emitting diode (micro LED) display and a manufacturing method thereof. Background technique [0002] Generally speaking, figure 1 The micro light emitting diode (micro LED) display 1 mainly includes a semiconductor substrate 10, a plurality of aluminum connection pads 20, a first protective layer 30, a second protective layer 40, and at least one redistribution layer (Redistribution Layer, RDL) 50 , at least one under-bump metallization layer 60 and at least one copper bump 70 . [0003] However, the micro LED display 1 has no touch function. [0004] Therefore, how to provide a touch-sensing circuit capable of configuring a micro LED display is an important issue for the industry to consider. SUMMARY OF THE INVENTION [0005] In view of the foregoing, one aspect of the present disclosure provides a touch-type micr...
