1.Qualified Components

The key to led display screen is components, so qualified components are required. And standards for choose are high brightness, lower power consumption, long life span, durability and stability.

2.Failure Rate

It means the components failure rate should be within 0.03% from led display assemble to after aging more than 72 hours.

3.Antistatic Ability

LED display screen antistatic ability matters much to its life span for LED is semiconductor device and sensitive to static electricity. Frequent static electricity failure will reduce life span of led display.

In General, the failure voltage test of human body electrostatic led pattern should NOT be less than 2000V.

4.Flatness

LED display screen flatness should be better within 0≤a≤1mm to ensure the showing image is not distorted. Or local convex or concave will lead blind space to led display viewing angle.

5.Brightness and Viewing Angle

LED display screen while balance effect is mainly decided by LED Chip, as well as led display screen color reducibility.

7.Color Reducibility

LED display screen color reducibility refers to its color recovery. In another words, led display screen showed color should maintain high consistent with color resource to ensure the sense reality of play image.

8.Mosaic and Dead Point

Mosaic is square parts on led display screen always light or black. Also called module broken and stop work. And quantity of dead points on modules also decided by led chip quality.

9.Color Pieces

Color pieces refers to small area lack of color, which mainly caused by quality of driving IC, power supply, circuit board and flat cables.

10.Production process
