Abstract
The invention discloses a display panel, a manufacturing method of the display panel and a display device. The display panel comprises a substrate and a micro light-emitting device fixed to the substrate. A circuit board electrode is arranged on the substrate, and conductive photoresist is arranged at the position, corresponding to the micro light-emitting device, of the circuit board electrode; an electrode is arranged on the side, close to the underlayer substrate, of the micro light-emitting device, and the electrode is fixed to a circuit board electrode of the underlayer substrate throughthe conductive photoresist and electrically connected with the underlayer substrate. The conductive photoresist can be removed through exposure, development and the like, and heating treatment is notneeded in the exposure and development treatment process, so that the damage of the heating treatment to the solder and the electrode in the prior art is avoided.
Description
technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In the prior art, the metal circuit is made on the substrate, and most of the welding materials on the metal circuit are indium (In) and tin (Sn) at present, but these two materials need to be heated and melted before they can be welded, and multiple times of heating It will cause doubts about the oxidation of the soldering material, and more seriously, for the substrate, excessive heating times may also damage the metal circuit of the substrate. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a display panel, its manufacturing method, and a display device for the above-mentioned defects of the prior art, aiming at solving the p...
