Quality and Parameters of Dedicated LED for Full Color Led Screen

1. Failure rate

One full color led display is composed by over ten thousands and even hundreds of thousands of pixels consisting of Red, blue and green three LEDs, and the failure of any color of led will influence the overall displaying effect. Generally speaking, according to the industrial experience, the failure rate of the led panel display from assembly to the aging process of 72 hours should be lower than 0.03%.

2. Anti-static ability

As a semiconductor device, the LED light is very sensitive to static electricity, and it can easily cause the static electricity to lose efficacy, for this reason, the anti-static ability is paramount for the service life of the led display rentals. Generally speaking, the failure voltage of the human body static mode test of the led light should be no lower than 2000V.

3. Fading feature

The brightness of the three color led lights will fade along with the increase of working time, and the quality of LED chip, quality of the supplemental material and the encapsulation technical level will decide the fading speed.

4. Brightness

The brightness of the LED is an important decisive factor of the brightness of the electronic message board signs, and the bigger the margin of the used current is, the more goodness it will bring to save electricity consumption and stabilize of the led display screen. LED lights have different angle values, and under certain chip brightness, the smaller the angle is, the brighter the LED will be, and smaller the visual angle of the led wall display will be.

5. Consistency

Since a full color led wall display is assembled by the pixels composed by many red, green and blue LED lights, the brightness of every color of LED light and the consistency of the wave length will decide the consistency of brightness, white balance and color scale of the whole video display wall.
