Description
Technical field
It the utility model is related to LED encapsulation technologies field, and in particular to a kind of indoor display LED wrappers of high-contrast
Part.
Background technology
Surface-adhered type RGB LED are widely used in indoor display screen, and indoor display packaging is main in the market
The problem of in the presence of two aspects.First, contrast is relatively low.The functional areas cavity of the common LED packagings of in the market is larger, work(
The top horizontal size of energy area cavity is 1.6mm, bottom 1.35mm.Therefore, cavity top-surface area in functional areas is larger, makes
After the packaging plastic sealing of white, product surface colours white accounting is larger, and contrast is not high after upper screen.If in packaging plastic
Add black dose, the brightness to product has a great influence, can not meet terminal market with requiring.Second, poor air-tightness, product can
It is not high by property.According to terminal feedback, the common LED packagings of in the market are more than more than 100PPM using failure ratio,
Industry 5PPM requirement can not be met.For encapsulating factory, 100PPM crash rate can produce huge reimbursement of damages.Therefore,
To meet the needs of market, the contrast and reliability of lifting light-emitting diode display part are the directions that LED packagings are made great efforts.
Utility model content
In order to solve the above technical problems, we have proposed a kind of indoor display LED packagings of high-contrast, the wrapper
The piece optimization angle and size of functional areas cavitys, substantially increases contrast, brightness and reliability, and it is indoor aobvious to meet high definition
The requirement shown.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of indoor display LED packagings of high-contrast, including cup, support, chip, bonding line, pin and encapsulation
Glue；The cup is arranged on the support, and the color of the cup is black, 2.0 ± 0.3mm of the cup length, width
2.0 ± 0.3mm, height 0.8-2.0mm, the cup inner space are functional areas cavity, the top water of the functional areas cavity
Leveling ruler cun is 1.0 ± 0.3mm, and bottom level size is 0.7 ± 0.15mm, and the frame upper is Copper base material, in the function
In being provided with the chip in the Copper base material in area's cavity, the chip passes through the weldering on the bonding line and the Copper base material
Disk connects, and the pin extends to the Copper base material back side by the Copper base material front, and the packaging plastic is filled in the function
In area's cavity.
Preferably, the chip includes red light chips, green glow chip and blue chip.
Preferably, the material of the cup is PPA, PCT and EMC one kind therein.
Pass through above-mentioned technical proposal, the utility model are adopted by optimizing design to LED packagings size and structure
With black cup, while the volume of reduction capability area cavity, so as to reduce the LED packagings functional areas positive surface of cavity
Product, greatly improves the contrast of LED display, and the packaging adds the thickness of cup surrounding, improves LED wrappers
The air-tightness of part, the reliability of LED packagings utilization is improved, meets the requirement of the indoor display screen of high definition.
