Abstract
The invention relates to a welding method for a circuit board and a light-emitting device, a display module, a panel and solder. A mixed structure of three-dimensional ordered colloidal crystals and nano-silver is set on the first pad of the circuit board, and the nano-silver is filled in the gap of the three-dimensional ordered colloidal crystal; the first pad is bonded to the second pad of the light-emitting device ; The mixed structure of three-dimensional ordered colloidal crystals and nano-silver is sintered. After the mixed structure of three-dimensional ordered colloidal crystals and nano-silver is sintered, the three-dimensional ordered colloidal crystals are ablated to form a three-dimensional ordered hole structure, and nano-silver is formed. The three-dimensional ordered nano-silver structure, the three-dimensional ordered nano-silver structure realizes the connection between the first pad and the second pad, thereby reducing the reflectivity and refractive index of the first pad on the circuit board to light; further, The three-dimensional ordered hole structure formed by the ablation of the three-dimensional ordered colloidal crystal can effectively dissipate heat from the circuit board and the light-emitting device, thereby reducing the power consumption of the display module.
Description
technical field [0001] The invention relates to the field of display screens, in particular to a welding method for a circuit board and a light-emitting device, a display module, a panel and solder. Background technique [0002] Mini Light Emitting Diode (Mini-LED) display is a new display technology based on inorganic semiconductor light-emitting diode (Light-emitting diode, LED), and the distance between lamp beads is between 0.6-1.2mm. Mini-LED display is used in Large-screen high-definition display, such as monitoring and command, high-definition studio, high-end cinema, medical testing and other professional fields or outdoor advertising, conferences and exhibitions, office display and other commercial fields. In the related technology, the Mini-LED display module uses a printed circuit board (Printed Circuit Board, PCB) as the circuit board, and the pads on the PCB will reflect and refract light, thereby affecting the vision of the Mini-LED display module. display eff...
