Problems solved by technology
In the existing technology, SMD LEDs have been unable to break through the outdoor waterproof, moisture-proof and UV-proof packaging technology, so the traditional packaging structure of Lamp is still used in the outdoor display market.
At present, SMD materials adopt PLCC 6 and PLCC 4 structures. Among them, the hygroscopic characteristics of the PPA plastic used in PLCC lead to poor waterproof and moisture-proof effects of the product. LEDs used in outdoor displays often have bad phenomena such as dead lights, and the products are reliable. poor sex

The invention is suitable for the technical field of LEDs (light emitting diode) and discloses an LED packaging method, an LED packaging structure and a display screen. The packaging method comprises the steps of arranging a lead frame, respectively arranging an upper packaging shell and a lower packaging shell on the upper surface and the lower surface of the lead frame, filling lower packaging glue in the lower packaging shell, placing an LED chip in the upper packaging shell, connecting the LED chip on the lead frame, and filling upper packaging glue in the upper packaging shell. The packaging structure comprises the lead frame and the LED chip, wherein the upper side and the lower side of the lead frame are respectively provided with the upper packaging shell and the lower packaging shell, the LED chip is arranged in the upper packaging shell and is fixedly connected on the lead frame, the upper packaging shell is internally provided with the upper packaging glue which covers on the LED chip, and the lower packaging shell is internally provided with the lower packaging glue. The display screen is provided with the LED packaging structure. According to LED packaging method, the LED packaging structure and the display screen, the LED packaging structure adopts a double-layer packaging design, so that the product performance is high.
Description
technical field [0001] The invention belongs to the technical field of LEDs, and in particular relates to a packaging method of a chip type LED, an LED packaging structure and a display screen including the LED packaging structure. Background technique [0002] LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electricity into light. It changes the principle of incandescent lamp tungsten filament luminescence and energy-saving lamp three-based toner luminescence, and uses electric field luminescence. The characteristics of LED are very obvious: long life, high luminous efficiency, no radiation and low power consumption. [0003] The spectrum of LED is almost all concentrated in the visible light frequency band. The LED light source can use the principle of red, green and blue three primary colors. Under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily to produce 256×256×256= 1677...
