    Abstract: A connector assembly includes a connector and a flat cable. The connector includes a first terminal, a second terminal, a first body, a second body, a metal plate, a third body, and a shell. The first and second terminals electrically connect a first side and a second side of the flat cable respectively and are respectively contained in a first capacity slot and a first through-hole of the first body and in a second capacity slot and a second through-hole of the second body. The first and second bodies clamp the metal plate. The third body partly winds and fixes the first body and the second body, and protects a terminal conductive contact part of the flat cable connected by the first and second terminals to form the connector. The flat cable connects to the connector directly. There is no need for a fixed rigid printed circuit board.

  • Publication number: 20220025259
    Abstract: A quantum-dot light emitting diode includes, in sequential order from bottom to top, a LED light source, a quantum-dot photoresist layer and a barrier layer. The quantum-dot photoresist layer has a thickness lower than 20 ?m and is formed by specific material, so as to decrease a step difference between the quantum-dot photoresist layer and a light exit surface of the LED light source, to improve coating property of the barrier material and make sure that the coating of the barrier material can be implemented by dry coating or wet coating; the barrier material is not easy to crack to cause air leakage and oxidation because of thermal expansion and contraction, so as to increase the success rate of side packaging and the reliability of the process, and extend the reliability of the material.
