LED packaging structure capable of driving string lights and display screen through carrier waves and drive unit of LED packaging structure

Abstract

The invention provides an LED packaging structure capable of driving string lights and a display screen through carrier waves and a drive unit of the LED packaging structure. An LED is a three-primary-color (RGB) LED. Only the power input (output) end and loop end pins are arranged outside a shell, and an extension part is formed inwards. The drive unit, a red ray (R) LED dice, a green ray (G) LED dice and a blue ray (B) LED dice can be directly arranged in the shell in a solid-phase crystallization manner. All the light-emitting dices can be directly connected with an external power supply, and a drive mechanism is arranged in the drive unit and used for controlling the LED dices of the three primary colors; and meanwhile through the arrangement configuration of all the components in the structure, the LED with the high compactness, good light mixing effect and high resolution can be formed, the use space is reduced effectively, the number of the pins is reduced, and accordingly the production cost is lowered.

Description

technical field [0001] The present invention is an LED package structure, and the LED is more particularly a package structure of a three-primary-color LED that uses a carrier to drive a light string and a display screen and contains a drive unit inside and its drive unit, which can be applied to various LED displays The display effect of screen or light string and special light and shadow. Background technique [0002] Known full-color LEDs, in order to achieve various color presentations, each full-color LED package structure includes red (R) LED chips, green (G) LED chips and blue (B) LED chips. Use the three primary colors of red light (R), green light (G) and blue light (B) to mix ever-changing light colors, but because the ratios of RGB three primary colors required by various light colors are different, so full-color light-emitting diodes 10 Both need an external connection with a limited current group and a drive unit to effectively and accurately control the light ...

AI Technical Summary

Problems solved by technology

[0004] As mentioned above, although the existing technology discloses the technology of encapsulating the driving unit into the full-color LED, it can effectively solve the shortcomings of the aforementioned conventional technology using printed circuit boards, and effectively reduce the space and increase the density of the full-color LED. In this full-color LED structure, there are still many working components inside and there are too many pins, so the production yield and work efficiency are not good. In view of this, in order to further improve, the present invention discloses a method that uses a carrier wave to drive The LED packaging structure of the light string and the display screen and its drive unit are aimed at achieving the unique characteristics of various colors of the LED while maintaining its mass production method using automated machinery and tools. The various effects of signal transmission control lighting changes can be realized by means of signal transmission, and at the same time, the problems of too many components and complicated pins in the conventional full-color LED packaging structure can be reduced.
