Recently, LED Display is widely used in fields of indoor and outdoor media advertising, stage rental, hotel and restaurant, financial service, video reference, sports matching, entertainment and traffic etc. It could be divided into indoor and outdoor commercial advertising led display, stage rental led display, floor led display, stadium led display and traffic led display etc.

Facing the uneven quality as market developing, how customers choose qualified LED screen in a fast way? Jekaz Technology PROVIDE below points and hope can help.

1.Qualified Components

The key to LED signage 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 screen assemble to after aging more than 72 hours.

3.Antistatic Ability

LED 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 digital screen.

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

4.Flatness

LED Display 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 screen viewing angle.

5.Brightness and Viewing Angle

To guarantee the clear showing effect, outdoor LED screen brightness should be over 6500nits while indoor no more than 2000nits. Otherwise it can’t guarantee the good showing and watching effect. This is also why led display widely used in high brightness requirement outdoor environment. And brightness is mainly decided by led chip quality.

Viewing Angle directly decided led display visual area. To LED billboard viewing angle, much wider the better. Its wider or not matters tightly to led chip quality too.

6.White Balance Effect

The white balance effect is one of the most important indicators to led display. To LED signs , pure white only showed when red, green and blue color are with the proportion of 3:6 :1 and any proportion difference will affect white balance deviation which will influence LED Display play effect..

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

7.Color Reducibility

LED screen color reducibility refers to its color recovery. In another words, led billboard 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 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

The production process is the most intuitive and original way to evaluation led signage quality. For any process rough operation will increase its failure rate.

Jekaz Team hope above 10 tips can help you find the reliable LED screen producs and bring you more benefits than what you invested. If there any questions, you are always welcome to mail us at info@jekaz.com.
