Abstract
A method for making a micro LED display panel not requiring high-accuracy or individual positioning includes providing a carrier substrate with micro LEDs, providing a TFT substrate including a driving circuit, and forming a conductive connecting element, an insulating layer, and a contact electrode layer on the TFT substrate. The insulating layer and the contact electrode layer are patterned to define a through hole, the first electrode is placed against the contact electrode layer, and different voltages Vref and Vdd are applied to the contact electrode layer and to the conductive connecting element respectively, creating an electrostatic attraction. The micro LEDs and the first electrode are transferred from the carrier substrate onto the TFT substrate; and the conductive connecting element is bonded to the first electrode. The method of making is simple. A micro LED display panel made by the method is also provided.
