LED MODULE, LED PANEL AND LED SCREEN Russian patent published in 2019 - IPC H01L23/498 

FIELD: lighting engineering.

SUBSTANCE: present invention relates to the field of LED displays. Proposed are the LED module, LED panel and LED screen. LED module contains a composite layer, at least one set of LED chips, at least one driver integrated circuit (IC); while the specified composite layer contains a substrate located on the front side; LED chip and driver integrated circuit are installed on the front side of the composite layer, the cathode of the LED chip is connected to the driver integrated circuit with a glued gold wire, and many blind holes are made on the front side of the composite layer. Anode of the LED chip is connected to the positive electrode inside the composite layer through one of the blind holes. Wire from the VDD stem of the driver integrated circuit is connected to the positive electrode inside the composite layer through at least one of the blind holes. Wire coming from the GND leg of the driver integrated circuit is connected to the negative electrode inside the composite layer through one of the blind holes. At least one driver integrated circuit is connected to other driver integrated circuits via a signal line.

EFFECT: invention provides the ability to significantly reduce the complexity of the circuit pattern on the layer, the LED chip and the driver integrated circuit can be installed in the specified composite layer with high density, thus providing LED screen with perfect display, and since the dimensions of the unpackaged LED chip and unpackaged driver integrated circuit are extremely small and almost imperceptible to the human eye, the creation of a LED screen with high transparency is ensured.
