A kind of led packaging structure

Abstract

The invention relates to the field of LED packaging, and more particularly relates to an LED packaging structure capable of realizing static display. It includes at least one set of LED light-emitting chips, a PCB board, and a TFT control circuit module that controls at least one set of LED light-emitting chips. The TFT control circuit module and at least one set of LED light-emitting chips are packaged on the PCB to form a COB structure. The TFT control circuit The module is provided with electrodes connecting at least one group of LED light-emitting chips, and a sealant layer is formed on the TFT control circuit module and at least one group of LED light-emitting chips. In the present invention, the LED lamp bead or the TFT control circuit module in the LED module directly controls the LED light-emitting chip, and controls whether the LED light-emitting chip is lit through the TFT site selection, and ensures continuous power supply through the TFT control circuit module after the site selection is completed. Make the LED chip emit light continuously, and it can realize static display when applied to the display screen.

Description

technical field [0001] The invention relates to the field of LED packaging, and more particularly relates to an LED packaging structure capable of realizing static display. Background technique [0002] In recent years, LED displays have developed rapidly. From the initial large-pitch, low-definition outdoor display to the current small-pitch, ultra-high-definition indoor high-end display, the technical difficulty is constantly escalating, and customers' requirements for display performance are also increasing. The higher the LED, the smaller the LED has become its development trend. But small LED lamp beads are not the key to making high-density static screens. Although traditional discrete devices can be used in the prior art to achieve static display, this solution is point-to-point control through the driver IC, that is, one output channel only controls one LED light-emitting chip, so more driver ICs or increased output channels are required. At the same time, the wiri...

But small LED lamp beads are not the key to making high-density static screens

Although traditional discrete devices can be used in the prior art to achieve static display, this solution is point-to-point control through the driver IC, that is, one output channel only controls one LED light-emitting chip, so more driver ICs or increased output channels are required. At the same time, the wiring density and complexity of the PCB board will also increase. More ICs will increase the power consumption of the display screen, and the complex PCB board process will lead to poor yield and high cost, resulting in the entire display Increase in screen cost
