Abstract

The invention relates to the technical field of semiconductors, and discloses a packaging structure and a display device. The packaging structure comprises a metal support, a driving chip, a light-emitting assembly, a packaging piece and a metal cover plate. Wherein the metal support comprises a plurality of pins, a first face and a second face, the first face and the second face are oppositely arranged, the driving chip is arranged on the first face of the metal support and used for controlling the light-emitting state of the light-emitting assembly, and the light-emitting assembly is arranged on the second face of the metal support and electrically connected with the driving chip through the metal support. The packaging piece is arranged on the metal support, the packaging piece fixes the metal support and wraps the driving chip and the light-emitting assembly, the pins surround the driving chip and are partially exposed out of the packaging piece, and the metal cover plate is arranged on the side, away from the light-emitting assembly, of the driving chip and covers the whole driving chip. According to the packaging structure and the display device provided by the invention, the signal interference problem of the driving chip in the prior art can be solved, so that the use performance of a product is greatly improved.

Description

technical field [0001] The present application relates to the field of semiconductor technology, and in particular, to a packaging structure and a display device. Background technique [0002] Light-emitting diode (LED) is a solid-state semiconductor device that can convert electrical energy into visible light. It uses a solid semiconductor chip as a light-emitting material, and releases energy through the recombination of carriers, causing photon emission and directly converting electrical energy. for light energy. [0003] LED light sources are widely used in the field of display technology due to their advantages of high brightness, small size, low energy consumption and high stability. Among them, the key to improving the resolution of the LED display is to reduce the size of the LED packaging unit. [0004] In the related art, in order to reduce the size of the LED packaging unit, a vertical packaging structure is designed, that is, the LED chip and the driving chip a...
