Abstract

The invention provides an LED lamp bead board and a manufacturing method thereof, and a display panel. An upper substrate and a lower substrate are combined to form a substrate; through holes are independently formed in the upper substrate, blind holes are independently formed in the lower substrate, a mature process can be adopted, metal heat conduction columns are arranged in the through holes,the metal conducting layers are formed in the blind holes and the corresponding metal coatings are formed on the upper substrate and the substrate. the universality is good, implementation is easy, efficiency and yield are high, cost is low, and mass production, popularization and application are easy; compared with a single-layer substrate with the same thickness, the substrate formed by the upper substrate and the lower substrate has the advantages that the height of the metal heat conduction columns is only half of or even smaller than the height of the metal heat conduction columns, used for enabling heat generated by the LED chips to be generated everywhere, in the single-layer substrate, so that heat dissipation paths can be greatly reduced, and the heat dissipation performance is better.

Description

technical field [0001] The invention relates to the field of light-emitting diodes, in particular to an LED lamp bead board, a manufacturing method thereof, and a display panel. Background technique [0002] At present, mobile communication terminals such as laptops, tablets, and mobile phones have higher and higher color gamut and brightness requirements for backlight light sources, and the thickness is getting thinner and thinner. The original bracket-type LED light source has gradually been unable to meet this small size, high brightness requirements. Therefore, in order to reduce the size of the bracket-type LED bead light source, a substrate-type LED light source has been proposed in the industry. This technology requires forming blind holes on a single-layer substrate and forming through holes communicating with the blind holes at corresponding blind hole positions. Through holes and blind holes are drilled from the front and back of the single-layer substrate respec...
