Description

technical field [0001] The invention relates to a manufacturing method of a micro-LED display panel and a micro-LED display panel. Background technique [0002] The production process of the micro LED (miniature light emitting diode) panel in the prior art is as follows: firstly, micro LEDs are respectively installed on the backplane, and a first insulating layer, a conductive layer and a second insulating layer are deposited. Wherein, the above-mentioned first insulating layer, conductive layer and second insulating layer are all completed by masks. When installing micro-LEDs, special attention should be paid to the accuracy of the installation position of micro-LEDs, otherwise, errors in the alignment of micro-LEDs will cause deviations in the micro-LED array as a whole, which will further affect each deposition layer (mainly including the first misalignment of an insulating layer, a conductive layer and a second insulating layer). [0003] Specifically, the alignment er...

Problems solved by technology

[0003] Specifically, the alignment error of the above-mentioned micro-LEDs will, on the one hand, cause a short circuit in the conductive layer; Moreover, the deviation of the micro-LED in the direction perpendicular to the backplane will also cause the thickness control of the first insulating layer, the conductive layer and the second insulating layer to be difficult; and, because the deposition of the first insulating layer, the conductive layer In the process of forming and second insulating layer, it is necessary to rely on the light-shielding plate to make patterns, thus adding extra time and reducing work efficiency; and because in the production process of the prior art, the conductive layer is completely connected to every micro-LED on the backplane, When it is necessary to control some micro-LEDs individually, it cannot be realized because it will affect other micro-LEDs

According to the above situation, it can be seen that the production method in the prior art has a lot of inconvenient operation, which not only affects the quality of the product, but also causes a decrease in work efficiency, affects output, and has poor user experience.
